Description

[Detailed Description of the Invention] This invention relates to a suspension structure of a box body formed of a combination of bent steel plates and the like.

Conventionally, the structure of the hanging part of this type of box body is as shown in Fig. 1 and Fig. 2.
There was something shown in the figure.

FIGS. 1 and 2 show a suspension structure at a corner of a part of the box.

In the figure, 1 is a combination member formed by cutting out and bending the corners of a steel plate, etc., and forming the frame of the box, and the butted combination parts 11 of this combination member 1 are welded, 2 is an eye bolt for lifting the box; 3 is a cover that closes one side after the combination members 1 are assembled, and is fixed by welding.

In such a suspension structure of the box, the combined parts 11 are welded as necessary to increase the strength of the bent portions, thereby preventing deformation when suspended by the eye bolts 2.

Since the structure of the hanging part of a conventional box body is constructed as described above, it is necessary to increase the bending strength by welding, etc., and in order to improve the appearance, the combined part must be processed after welding to give it a curved surface finish. Since this method requires a number of procedures, it has disadvantages such as a large number of steps and a long schedule.

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above. By making the combination part an inset type and tightening the cover with screws, it is possible to suspend the box body by increasing the strength of the bent part. The purpose is to provide a partial structure.

An embodiment of this invention will be described below based on the drawings.

As shown in FIGS. 3 and 4, the hanging portions of the combination portion 11 of the combination member 1 made of bent steel plates are formed in a fitting manner and assembled.

Hanging with eye bolt 2 r) To prevent deformation when lifted, combine part 1
1 is a built-in type to prevent it.

Further, by screwing the cover 3 to the combination part 11, there is no deviation in the plate thickness direction of the combination part 11, and even if welding is omitted, the suspension load can be sufficiently coped with.

In the above embodiment, the fitting corresponds only to the load in the eye bolt direction, but if it is formed as shown in FIG. 5, it can also correspond to the load in the lateral direction.

As described above, according to this invention, since the suspension structure of the box body is formed by an inset type, the box body can be made at low cost.
It also has the effect of reducing the number of steps and speeding up the schedule.

[Brief explanation of drawings]

Figure 1 is a front view of a conventional box, Figure 2 is a side view of Figure 1, Figure 3 is a front view of a box according to an embodiment of this invention, and Figure 4 is a side view of Figure 3. Figure 5 shows a modification of this invention. In the figure, 1 is a combination member, 11 is a combination part, 2 is an eye bolt, 3 is a cover, and 4 is a screw. Note that the same reference numerals in the figures indicate the same or equivalent parts.
