In the following description, a detailed structure will be presented for a thorough understanding of the embodiments of the present invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

First embodiment

The present embodiment provides a rack type container. Referring to fig. 2 and 3, the rack container includes a bottom frame 120 and an end frame 110. The end frame 110 includes corner posts 111 and end beams 112. The free ends of the corner posts 111 are fixedly connected to the end beams 112.

The lower end of the end frame 110 remote from the end beam 112 (the connecting end of the corner post 111) has a first connecting assembly 130. The first connection assembly 130 may include a connection arm. The connecting arm may be configured as a plate. The thickness direction of the connection arm extends in the width direction Y of the chassis 120. The first connection assembly 130 is for connection to the connection end of the corner post 111. The first connection member 130 includes a first connection hole and a first locking hole.

The chassis 120 has a second connection assembly 140. The second connection assembly 140 is located at a corner of the chassis 120. The second connection assembly 140 may include a connection member 143 and a semi-open corner member 141. The connecting member 143 is a plate member. The thickness direction of the connector 143 extends in the width direction Y of the chassis 120. The connector 143 is for attachment (e.g., a welded connection) to the chassis 120. The link 143 is provided with a second coupling hole and a second locking hole.

The axis of the first coupling hole, the axis of the first locking hole, the axis of the second coupling hole, and the axis of the second locking hole all extend in the width direction Y of the chassis 120.

The rack container further includes a connecting shaft 150. The axial direction of the connecting shaft 150 extends in the width direction Y of the base frame 120. The connecting shaft 150 is inserted through the first and second connecting holes. Thus, the first and second connecting

members

130 and 140 are pivotally connected by the connecting shaft 150. In this way, the end stile 110 can be flipped between the erected position and the folded position in the directions C and D. With the end stile 110 in an upright position (the position of the end stile 110 shown in fig. 2 and 3), the end stile 110 and the chassis 120 are substantially perpendicular. With the end frame 110 in the folded position, the end frame 110 overlies the base frame 120.

The end frame 110 also has a stacking assembly 160. The stacking assembly 160 may be a plate. The thickness direction of the stacker assembly 160 extends in the height direction of the base chassis 120. The stacking assembly 160 is connected to the corner posts 111. In this manner, the stacking assembly 160, the first coupling assembly 130, and the end frame 110 may move together.

Preferably, the stacking assembly 160 is fixedly attached (e.g., welded) to the first connection assembly 130.

The stacking member 160 is located at a side of the first coupling member 130 along the width direction Y of the bottom chassis 120. With the end frame 110 in the upright position, the stacking assembly 160 is positioned above the second connecting assembly 140 and overlaps the second connecting assembly 140. With the end frame 110 in the collapsed position, the stacking assembly 160 is moved away from the second connecting assembly 140.

The free end of the end stile 110 (the end of the end stile 110 distal from its lower end) when in the erected condition is subjected to a first force. The direction of the first force extends in the width direction Y of the chassis 120. The first acting force can cause the free end of the end bell 110 to have a tendency to move in the width direction Y of the bottom chassis 120. At this time, the end frame 110 can press the stacking assembly 160 against the semi-open corner member 141 of the second connecting assembly 140 to overcome the first force acting on the end frame 110.

It is to be understood that the first force may not be applied to the free end of the end bell 110. As long as the point of action of the first force is above the second connecting member 140 with the end frame 110 in the upright position.

It will be appreciated that in one embodiment, not shown, portions of the free ends of the corner posts may constitute a stacking assembly. In another embodiment, not shown, a portion of the first coupling member may extend and protrude in the width direction Y of the base frame to constitute a stacking member.

Preferably, the number of the connecting members 143 is two. The two connectors 143 are spaced apart in the width direction Y of the chassis 120. The semi-open corner member 141 is connected to the upper end of the connection member 143. The semi-open corner fitting 141 has an open notch. There is a positioning space between the link 143 and the first link assembly 130 in the width direction Y of the base frame 120. The connector 143 is located outside the opening notch and on a side of the opening notch in the width direction Y of the chassis 120.

With the end stile 110 in the upright position, a portion of the first linkage assembly 130 is positioned within the open gap and between the linkage arms. When the free end of the end frame 110 in the upright position is subjected to a first force, the first connecting component 130 may abut against the portion of the semi-open corner member 141 surrounding the open notch, thereby overcoming the action of the first force on the end frame 110.

The stacking assembly 160 includes a first stacking member 161 and a second stacking member 162. The first stacking member 161 is located on an inner side of the first link assembly 130 in the width direction Y of the bottom chassis 120 (a side of the first link assembly 130 close to the center of the bottom chassis 120 in the width direction Y of the bottom chassis 120). Thus, when the first force is directed toward the center of the bottom chassis 120 along the width direction Y of the bottom chassis 120, the first stacking member 161 may overcome the effect of the first force on the end frame 110.

The second stacking member 162 is located at an outer side of the first coupling member 130 in the width direction Y of the bottom chassis 120 (a side of the first coupling member 130 away from the center of the bottom chassis 120 in the width direction Y of the bottom chassis 120). Thus, when the first force is applied away from the center of the bottom chassis 120 along the width direction Y of the bottom chassis 120, the second stacking member 162 can overcome the effect of the first force on the end frame 110.

The rack container further includes a locking shaft 170. The axis of the locking shaft 170 extends in the width direction Y of the chassis 120. The locking shaft 170 is inserted into the first locking hole and the second locking hole when the end frame 110 is in the upright state. Thus, the locking shaft 170 and the connecting shaft 150 cooperate to fix the relative position between the first connecting member 130 and the second connecting member 140 and prevent relative movement between the first connecting member 130 and the second connecting member 140.

The stacker assembly 160, which is overlapped to the semi-open corner member 141, enables the first locking hole and the second locking hole to be coaxially disposed with the end frame 110 in the erected state. In this way, the first connection assembly 130 can be positioned to facilitate installation of the locking shaft 170.

Preferably, the stacking assembly 160 is located at an outer side of the connecting shaft 150 along the length direction X of the bottom chassis 120 (a side of the connecting shaft 150 away from the center of the bottom chassis 120 along the length direction X of the bottom chassis 120, a side indicated by an arrow "out" in fig. 3). Thus, when the end stile 110 in the erected position is subjected to a second force that causes the end stile 110 to flip in the direction C away from the folded position, the end stile 110 can cause the stacking assembly 160 to press against the semi-open corner member 141 of the second connector assembly 140 to overcome the second force acting on the end stile 110. The second force is along the length direction X of the chassis 120 and near the center of the chassis 120. The second acting force acts on the end stile 110 in the erected state at a position above the connecting shaft 150.

Further, the arrangement of the stacking assembly 160 outside the connecting shaft 150 in the length direction X of the base frame 120 enables the end frame 110 to be turned between the erected state and the folded state.

In this embodiment, when the end frame 110 in the upright state receives a first acting force in the direction along the width direction Y of the bottom frame 120, and no matter the direction of the first acting force is toward or away from the center of the bottom frame 120, the end frame 110 can press the stacking assembly 160 against the second connecting assembly 140 to overcome the effect of the first acting force on the end frame 110, and when the end frame 110 in the upright state receives a second acting force in the direction along the length direction X of the bottom frame 120 away from the center of the bottom frame 120, the arrangement of the stacking assembly 160 against the second connecting assembly 140 can overcome the effect of the second acting force on the end frame 110, so that the end frame 110 can be stably in the upright state.

Four corners of the bottom chassis 120 are each provided with one first coupling assembly 130, one second coupling assembly 140, and one coupling shaft 150. At each corner of the bottom chassis 120, a connection shaft 150 connects the first connection assembly 130 and the second connection assembly 140.

Preferably, the stacking assembly 160 is positioned between the end frame 110 and the second connecting assembly 140 with the end frame 110 in an upright position. In this way, when the platform container is stacked and transported with the end frame 110 in the upright state, the corner posts 111 can transmit the acting force in the height direction of the bottom frame 120 to the bottom frame 120 via the stacking assembly 160, so as to achieve stacking.

Second embodiment

In the second embodiment, as shown in fig. 4 and 5, the end frame of the rack type container includes corner posts 211, end beams 212, and a disassembly shaft 213. The corner post 211 has a first mounting hole. The end beam 212 has a second disassembly hole. The mounting shaft 213 is detachably inserted into the first mounting hole and the second mounting hole, thereby connecting the corner post 211 and the end beam 212. In this way, the end beam 212 is detachably connected to the corner post 211.

In the second embodiment, each end of the underframe of the rack type container is provided with two first connection assemblies 230, two second connection assemblies 240, and one connection shaft 250.

In each end of the chassis, two first connection members 230 are provided to correspond to two second connection members 240. The first connection assembly 230 is connected to the corresponding second connection assembly 240. A connecting shaft 250 extends from one side end of the bottom frame to the other side end, such that the connecting shaft 250 is inserted through the two first connecting members 230 and the two second connecting members 240.

Specifically, the connecting shaft 250 includes a connecting sleeve 251 and a connecting shaft center 252. There are two connection axes 252. A connecting shaft 252 is inserted through one end of the connecting sleeve 251. The other connecting axis 252 passes through the other end of the connecting sleeve 251. The connection hub 252 and the connection sleeve 251 are fixedly connected (e.g., welded).

A connecting shaft 252 is inserted through and fixedly connected (e.g., welded) to a first connecting hole of a first connecting element 230. The other connecting shaft 252 is inserted through and fixedly connected (e.g., welded) to the first connecting hole of the other first connecting element 230.

The rack container also includes a sleeve 290. Portions of the sleeve 290 are disposed through the second coupling holes. The boss 290 has a central bore. There are two bushings 290. A bushing 290 is coupled to the second coupling aperture of a second coupling assembly 240. The other bushing 290 is coupled to the second coupling hole of the other second coupling assembly 240.

A connecting shaft core 252 of the connecting shaft 250 is rotatably inserted through a central hole of a bushing 290. The other connecting hub 252 is rotatably disposed through the central bore of the other sleeve 290.

Further, the sleeve 290 has a positioning portion. The positioning portion is located in a positioning space between the link 243 and the first connection assembly 230. The positioning surface 246 of the positioning part is substantially flush with the inner surface 247 of the opening notch 242 of the half-open corner fitting 241 (the side surface of the opening notch 242 closer to the center of the chassis in the width direction Y of the chassis). The first coupling member 230 and the positioning surface 246 substantially conform (e.g., a distance between the first coupling member 230 and the positioning surface 246 is small (e.g., 0.5mm to 2mm) in the width direction Y of the base frame so that the first coupling member 230 can rotate relative to the coupling sleeve 251).

In this way, the positioning portion may position the first connection assembly 230 so that the first connection assembly 230 is located at the opening gap 242, and thus the opening gap 242 can be accessed. Therefore, the connecting component is convenient to mount.

It will be appreciated that in an embodiment not shown, the locating surface is located on the side of the inner side facing away from the centre of the chassis in the width direction Y of the chassis.

Other configurations of the second embodiment are substantially the same as those of the first embodiment, and are not described herein.

Third embodiment

In the third embodiment, as shown in fig. 6 and 7, the rack type container further includes a positioning part 344. The positioning part 344 may be a plate. The thickness direction of the positioning portion 344 extends in the width direction Y of the chassis. Positioning portion 344 is fixedly coupled (e.g., welded) to coupling member 343. Positioning part 344 is located in the positioning space between connecting piece 343 and first connecting assembly 330. The positioning surface 346 of the positioning portion 344 is substantially flush with the inner side surface 347 of the open notch 342 (the side surface of the open notch 342 closer to the center of the bottom chassis 320 in the width direction Y of the bottom chassis).

The first coupling member 330 and the positioning surface 346 generally conform [ along the width direction Y of the chassis, the distance between the first coupling member 330 and the positioning surface 346 is small (e.g., 0.5mm to 2mm) to enable the first coupling member 330 to rotate relative to the link 343 ].

In this way, the positioning portion 344 may position the first connection assembly 330 such that the first connection assembly 330 is located at the open notch 342 of the semi-open corner member 341, thereby enabling the open notch 342 to be accessed. Therefore, the connecting assembly is convenient to mount.

It will be appreciated that in an embodiment not shown, portions of the connector may extend and protrude in the width direction Y of the chassis to constitute the positioning portions.

The corner post 311, the first locking hole 331, the second connecting assembly 340, the semi-open corner fitting 341, the second locking hole 345, the connecting shaft 350, the second stacking member 362, and the locking shaft 370 of the third embodiment are substantially the same as the corner post 111, the first locking hole, the second connecting assembly 140, the semi-open corner fitting 141, the second locking hole, the connecting shaft 150, the second stacking member 162, and the locking shaft 170 of the first embodiment.

Other configurations of the third embodiment are substantially the same as those of the first embodiment, and are not described herein again.

Fourth embodiment

In the fourth embodiment, as shown in fig. 8 and 9, the rack container further includes a reinforcement 480. The reinforcement 480 may be a plate. The thickness direction of the reinforcement 480 extends in the width direction Y of the chassis. The reinforcement 480 is fixedly connected (e.g., welded) to the first connection member 430. The reinforcement 480 is located at a side of the first connection module 430 in the width direction Y of the chassis. As such, the reinforcement 480 may increase a local thickness of the first connection member 430, thereby increasing the strength of the first connection member 430. The reinforcement 480 exits the second connection assembly 440. In this way, interference between the reinforcement 480 and the second connection assembly 440 during the flipping of the end stile may be avoided.

It will be appreciated that in an embodiment not shown, a portion of the first connection assembly may extend to protrude in the width direction Y of the chassis to constitute a reinforcement.

The corner post 411, the semi-open corner member 441, the open notch 442, the connecting member 443, the connecting shaft 450, and the second stacking member 462 of the fourth embodiment are substantially the same as the corner post 111, the semi-open corner member 141, the open notch, the connecting member 143, the connecting shaft 150, and the second stacking member 162 of the first embodiment.

Other configurations of the fourth embodiment are substantially the same as those of the first embodiment, and are not described herein again.
