It is to be understood that, although directional terms, such as "front", "rear", "upper", "lower", "left", "right", etc., may be used in this application to describe various example structural components and elements of the present application, these terms are used herein for convenience of description only and are determined based on the exemplary orientations shown in the drawings. Because the embodiments disclosed herein may be arranged in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting.
Ordinal numbers such as "first" and "second" used in this application are used merely for distinguishing and identifying, and do not have any other meaning, and do not denote a particular order, nor have particular relevance, unless otherwise indicated. For example, the term "first clamping surface" does not itself imply the presence of "second clamping surface", nor does the term "second clamping surface" itself imply the presence of "first clamping surface".
Fig. 1A is a perspective view of the fastener 100, fig. 1B is a vertical sectional view of the fastener 100 shown in fig. 1A, and fig. 1C is a bottom view of the fastener 100 shown in fig. 1A. As shown in fig. 1A-1C, the fastener 100 includes a body 102, four clamp arms 104, and four abutment arms 106. The body 102 is annular. Four clamping arms 104 and four abutment arms 106 are formed extending from the body 102, respectively. Wherein four clamping arms 104 are configured to clamp a first piece 201 (see fig. 2A). The four abutment arms 106 are configured to grip the second piece 202 (see fig. 2A).
As shown in fig. 1A-1C, the body 102 is generally circular. Having a central axis X. In the radial direction of the main body 102, the middle portion of the main body 102 is upwardly arched, thereby forming an operation portion 122. When an operator uses the fastener 100 to connect the first piece 201 and the second piece 202, the operator can press the operating portion 122, thereby moving the fastener 100 toward the second piece 202.
As shown in fig. 1A to 1C, four clamp arms 104 are uniformly arranged in the circumferential direction of the main body 102. Each of the clamp arms 104 extends inwardly and obliquely upwardly from an inner edge of the body 102. For each gripping arm 104, it has oppositely disposed connecting end 132 and free end 134. Wherein the connecting end 132 is connected to the body 102. The four free ends 134 define therebetween an receiving cavity 108 for receiving a first member 201 (see fig. 2A).
As shown in fig. 1B, in an embodiment of the present application, the free end 134 includes a first gripping surface 141 and a second gripping surface 142. The first clamping surface 141 and the second clamping surface 142 are located at opposite ends of the free end 134 in the circumferential direction of the main body 102. The distance of the first clamping surface 141 and the second clamping surface 142 from the central axis X is slightly smaller than the radius of the second piece 202. The first 141 and second 142 clamping surfaces of the four clamping arms 104 are helically arranged so that the four clamping arms 104 can clamp on different heights of the post 214 of the first piece 201 when the first 141 and second 142 clamping surfaces clamp the first piece 201. When the four gripping arms 104 grip the first piece 201, the gripping arms 104 grip the first piece 201 from the first direction. As one example, the first direction is a radial direction of the body 102.
Further, as shown in fig. 1B, the cross-sectional shape of the four clamp arms 104 is substantially bowl-shaped. Each clamping arm 104 is further provided with a through hole 136. The through-hole 136 can enhance the deformability of the clamp arm 104, thereby enabling the fastener 100 to accommodate different sized first pieces 201.
Although the first clamping surface 141 and the second clamping surface 142 of the free end 134 are used to clamp the first member 201 in the embodiment of the present application, at least a portion of the free end 134 may be used to clamp the first member 201 in other embodiments. It should be further noted that, although the first clamping surface 141 and the second clamping surface 142 are located at opposite ends of the free end 134 in the circumferential direction of the main body 102 in the embodiment of the present application, at least a portion of the free end 134 for clamping the first member 201 may be located at any position of the free end 134.
As shown in fig. 1A to 1C, four abutment arms 106 are uniformly arranged in the circumferential direction of the main body 102 and are disposed between two adjacent clamp arms 104. In other words, the four clamp arms 104 and the four abutment arms 106 are disposed at intervals in the circumferential direction of the body 102. The abutment arm 106 is located below the clamping arm 104. Specifically, each abutment arm 106 extends upwardly after extending inwardly and downwardly a distance from the inner edge of the body 102. When the fastener 100 connects the first piece 201 and the second piece 202 in place, the second piece 202 is positioned below the fastener 100. Thus, in other words, each abutment arm 106 extends a distance inwardly from the inner edge of the body 102 and toward the second member 202 and then away from the second member 202.
Specifically, each abutment arm 106 includes a root 151, an extension 152, and a bend 153. The expansion portion 152 is disposed between the root portion 151 and the bending portion 153, and is connected to the root portion 151 and the bending portion 153. The root 151 is for connection with the inner edge of the body 102. In the circumferential direction of the body 102, the maximum circumferential length L1 of the expansion 152 is greater than the maximum circumferential length L2 of the root 151, so that the abutment arm 106 has a greater deformability, so that the abutment arm 106 can exert a greater abutment force on the second piece 202 when the abutment arm 106 abuts the second piece 202. The bottom surface of the bent portion 153 is lower than the bottom surface of the main body 102 for abutting against the second member 202. In other words, the bottom surface of the bent portion 153 is closer to the upper surface of the second member 202 than the bottom surface of the main body 102. When the bending portion 153 abuts against the second member 202, the bending portion 153 abuts against the second member 202 from the second direction. As an embodiment, the second direction is the direction of the central axis X. Wherein the second direction is substantially perpendicular to the first direction.
Further, as shown in fig. 1C, in the circumferential direction of the same main body 102, the circumferential length of the abutment arm 106 is longer than the interval length between the adjacent two clamp arms 104, thereby preventing the abutment arm 106 from moving above the clamp arms 104 by the interval between the adjacent two clamp arms 104 under the external force.
Fig. 2A is a perspective view of a first embodiment of the fastener assembly of the present application connected in place, fig. 2B is an exploded view of the fastener assembly shown in fig. 2A, and fig. 2C is a cross-sectional view of the fastener assembly shown in fig. 2A. As shown in fig. 2A-2C, the first piece 201 includes a base portion 212 and a post portion 214. The base 212 is substantially plate-shaped, and the column 214 is provided above the base 212 and connected to the base 212. The second member 202 is substantially plate-shaped. The second member 202 is provided with a second member through hole 222. As one example, the first piece 201 and the fastener 100 are made of metal. The second piece 202 is made of plastic.
As shown in fig. 2A-2C, when an operator desires to attach the first piece 201 and the second piece 202 with the fastener 100, the operator first places the second piece 202 over the post 214 of the first piece 201. The operator then installs the fastener 100 over the post 214 of the first member 201. When installing the fastener 100, the operator may align the central axis X of the body 102 with the central axis of the post 214 and then press the operating portion 122 of the fastener 100 to bring the post 214 into the receiving cavity 108. The post 214 contacts the first and second clamping surfaces 141, 142 of the free end 134 of the fastener 100 and moves the free end 134 away from each other to enlarge the receiving cavity 108 until the receiving cavity 108 is able to receive the post 214. In other words, the clamp arm 104 deflects about the connecting end 132 during abutment of the post 214 against the first and second clamp surfaces 141, 142 and moving the free ends 134 away from one another. Deflection of the clamp arm 104 about the connecting end 132 enables the first and second clamp surfaces 141, 142 of the free end 134 to continuously apply a clamping force to the post 214. After the post 214 passes through the receiving cavity 108, the operator continues to press the operating portion 122 until the bent portion 153 of the fastener 100 contacts the upper surface of the second member 202. The upper surface of the second member 202 abuts against the bottom surface of the bent portion 153, thereby deflecting the abutment arm 106 about the root 151. The deflection of the abutment arm 106 about the root 151 can cause the bottom surface of the fold 153 to continuously apply an abutment force against the upper surface of the second member 202, thereby compressing the first and second members 201, 202 together. After the bottom surface of the bending portion 153 abuts against the upper surface of the second member 202, the operator continues to press the operating portion 122 until the bottom surface of the main body 102 contacts the upper surface of the second member 202. Thus, the fastener 100 connects the first piece 201 and the second piece 202 in place.
Fig. 3A is a perspective view of a second embodiment of the fastener assembly of the present application connected in place, fig. 3B is an exploded view of the fastener assembly shown in fig. 3A, and fig. 3C is a cross-sectional view of the fastener assembly shown in fig. 3A. The fastener assembly shown in fig. 3A-3C is identical to the fastener assembly shown in fig. 2A-2C and will not be described in detail, the fastener assembly shown in fig. 3A-3C differs from the fastener assembly shown in fig. 2A-2C mainly in that: the fastener assembly of fig. 3A-3C is provided with threads 324 on the post 214 and the portion of the fastener 100 that is used to grip the free end 134 of the first member 201 is in a helical arrangement. The screw arrangement can mate with the screw threads 324. In one embodiment, threads 324 are M6 threads, with portions of free end 134 in a helical arrangement capable of mating with the M6 threads.
When it is desired to connect the first piece 201 and the second piece 202 with the fastener 100, an operator may operate as described in the first embodiment of fig. 2A-2C. When the fastener 100 connects the first piece 201 and the second piece 202 in place, the free end 134 can extend between two turns of the thread 324, and at least a portion of the free end 134 can abut the thread 324.
It should be noted that, although the fastener 100 of the present application includes four clamping arms 104 and four abutting arms 106, at least two clamping arms 104 and at least two abutting arms 106 are within the scope of the present application.
In the prior art, a fastener clamps a post portion of a first member by a clamp arm, thereby connecting the first member and a second member. However, the prior art clamp arms are prone to breakage. The inventors of the present application found that since the fastening of the first member and the second member is held by the clamp arm, the first member and the second member easily move therebetween. In other words, the second member is susceptible to relative movement in a horizontal direction (e.g., in a radial direction of the body 102) with respect to the first member, resulting in breakage of the clamp arms due to excessive force (e.g., radial force in the radial direction of the body 102).
The first piece 201 and the second piece 202 in the fastener assembly of the present application can be stably connected by the fastener 100. Specifically, the fastener 100 of the present application includes an abutment arm 106. Which is capable of compressing the base 212 of the first member 201 and the second member 202 to thereby hinder relative movement of the first member 201 and the second member 202 in a horizontal direction (e.g., in a radial direction of the body 102) to thereby avoid breakage of the clamp arm 104.
While the present disclosure has been described in conjunction with the examples of embodiments outlined above, various alternatives, modifications, variations, improvements, and/or substantial equivalents, whether known or that are or may be presently or later be envisioned, may be apparent to those of ordinary skill in the art. Further, the technical effects and/or technical problems described in the present specification are exemplary rather than limiting; the disclosure in this specification may be used to solve other technical problems and to have other technical effects and/or may solve other technical problems. Accordingly, the examples of embodiments of the disclosure as set forth above are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit or scope of the disclosure. Accordingly, the present disclosure is intended to embrace all known or earlier developed alternatives, modifications, variations, improvements and/or substantial equivalents.
