If not specifically specified, they do not indicate a specific order or have a specific association. For example, the term "first clamping surface" itself does not imply the existence of a "second clamping surface", and the term "second clamping surface" itself does not imply the existence of a "first clamping surface".
[0027] Figure 1A is a perspective view of the fastener 100, Figure 1B yes Figure 1A A vertical cross-sectional view of the fastener 100 is shown, Figure 1C yes Figure 1A FIG. 1 is a bottom view of the fastener 100 shown. Figures 1A-1C As shown, the fastener 100 includes a main body 102, four clamping arms 104 and four abutting arms 106. The main body 102 is annular. The four clamping arms 104 and the four abutting arms 106 are respectively extended from the main body 102. Among them, the four clamping arms 104 are configured to clamp the first piece 201 (see Figure 2A The four abutment arms 106 are configured to clamp the second piece 202 (see Figure 2A ).
[0028] like Figures 1A-1C As shown, the main body 102 is generally a circular ring having a central axis X. In the radial direction of the main body 102, the middle portion of the main body 102 is arched upward to form an operating 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 to move the fastener 100 toward the second piece 202.
[0029] like Figures 1A-1CAs shown, the four clamping arms 104 are evenly arranged along the circumferential direction of the main body 102. Each clamping arm 104 extends inwardly and obliquely upwardly from the inner edge of the main body 102. Each clamping arm 104 has a connecting end 132 and a free end 134 that are oppositely arranged. The connecting end 132 is connected to the main body 102. A receiving cavity 108 is formed between the four free ends 134 for receiving the first piece 201 (see Figure 2A ).
[0030] like Figure 1B As shown, in the embodiment of the present application, the free end portion 134 includes a first clamping surface 141 and a second clamping surface 142. In the circumferential direction of the main body 102, the first clamping surface 141 and the second clamping surface 142 are located at opposite ends of the free end portion 134. The distance between the first clamping surface 141 and the second clamping surface 142 and the central axis X is slightly smaller than the radius of the second piece 202. The first clamping surface 141 and the second clamping surface 142 of the four clamping arms 104 are arranged in a spiral shape, so that when the first clamping surface 141 and the second clamping surface 142 clamp the first piece 201, the four clamping arms 104 can clamp at different heights of the column 214 of the first piece 201. When the four clamping arms 104 clamp the first piece 201, the clamping arms 104 clamp the first piece 201 from the first direction. As an embodiment, the first direction is the radial direction of the main body 102.
[0031] In addition, if Figure 1B As shown, the cross-sectional shape of the four clamping arms 104 is substantially bowl-shaped. Each clamping arm 104 is also provided with a through hole 136. The through hole 136 can improve the deformation capacity of the clamping arm 104, so that the fastener 100 can adapt to first pieces 201 of different sizes.
[0032] It should be noted that, although the first clamping surface 141 and the second clamping surface 142 of the free end portion 134 in the embodiment of the present application are used to clamp the first piece 201, in other embodiments, at least a portion of the free end portion 134 can be used to clamp the first piece 201. It should also be noted that, although the first clamping surface 141 and the second clamping surface 142 in the embodiment of the present application are located at opposite ends of the free end portion 134 in the circumferential direction of the main body 102, at least a portion of the free end portion 134 used to clamp the first piece 201 can be located at any position of the free end portion 134.
[0033] like Figures 1A-1CAs shown, four abutment arms 106 are evenly arranged along the circumferential direction of the main body 102, and are arranged between two adjacent clamping arms 104. In other words, the four clamping arms 104 and the four abutment arms 106 are arranged at intervals along the circumferential direction of the main body 102. The abutment arms 106 are located below the clamping arms 104. Specifically, each abutment arm 106 extends inwardly and downwardly from the inner edge of the main body 102 for a distance, and then extends upward. When the fastener 100 connects the first piece 201 and the second piece 202 in place, the second piece 202 is located below the fastener 100. Therefore, in other words, each abutment arm 106 extends inwardly and toward the second piece 202 from the inner edge of the main body 102 for a distance, and then extends away from the second piece 202.
[0034] Specifically, each abutment arm 106 includes a root 151, an extension 152 and a bend 153. The extension 152 is disposed between the root 151 and the bend 153, and is connected to the root 151 and the bend 153. The root 151 is used to connect with the inner edge of the main body 102. In the circumferential direction of the main body 102, the maximum circumferential length L1 of the extension 152 is greater than the maximum circumferential length L2 of the root 151, so that the abutment arm 106 has a greater deformation capacity, so that when the abutment arm 106 abuts against the second piece 202, the abutment arm 106 can apply a greater abutment force to the second piece 202. The bottom surface of the bend 153 is lower than the bottom surface of the main body 102, and is used to abut against the second piece 202. In other words, the bottom surface of the bend 153 is closer to the upper surface of the second piece 202 than the bottom surface of the main body 102. When the bent portion 153 abuts against the second piece 202, the bent portion 153 abuts against the second piece 202 from a second direction. As an embodiment, the second direction is the direction of the central axis X. The second direction is substantially perpendicular to the first direction.
[0035] In addition, if Figure 1C As shown, in the circumferential direction of the same main body 102, the circumferential length of the abutment arm 106 is greater than the interval length between two adjacent clamping arms 104, thereby preventing the abutment arm 106 from moving through the interval between two adjacent clamping arms 104 to above the clamping arms 104 under the action of external force.
[0036] Figure 2A is a perspective view of a first embodiment of a fastener assembly of the present application connected in place, Figure 2B Yes Figure 2A An exploded view of the fastener assembly is shown. Figure 2C Yes Figure 2A A cross-sectional view of a fastener assembly is shown. Figures 2A-2CAs shown, the first piece 201 includes a base 212 and a column 214. The base 212 is generally plate-shaped, and the column 214 is disposed above the base 212 and connected to the base 212. The second piece 202 is generally plate-shaped. The second piece through hole 222 is provided on the second piece 202. As an embodiment, the first piece 201 and the fastener 100 are made of metal. The second piece 202 is made of plastic.
[0037] like Figures 2A-2C As shown, when the operator needs to use the fastener 100 to connect the first piece 201 and the second piece 202, the operator first sets the second piece 202 on the column 214 of the first piece 201. Then, the operator sets the fastener 100 on the column 214 of the first piece 201. When setting the fastener 100, the operator can align the central axis X of the body 102 with the central axis of the column 214, and then press the operating part 122 of the fastener 100 to make the column 214 enter the receiving cavity 108. The column 214 contacts the first clamping surface 141 and the second clamping surface 142 of the free end 134 of the fastener 100, and the free end 134 moves away from each other to expand the receiving cavity 108 until the receiving cavity 108 can receive the column 214. In other words, in the process that the column 214 abuts against the first clamping surface 141 and the second clamping surface 142 and moves the free end 134 away from each other, the clamping arm 104 deflects around the connecting end 132. The deflection of the clamping arm 104 around the connecting end 132 enables the first clamping surface 141 and the second clamping surface 142 of the free end 134 to continuously apply a clamping force to the column 214. After the column 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 piece 202. The upper surface of the second piece 202 abuts against the bottom surface of the bent portion 153, thereby deflecting the abutting arm 106 around the root 151. The deflection of the abutting arm 106 around the root 151 enables the bottom surface of the bent portion 153 to continuously apply abutting force to the upper surface of the second piece 202, thereby pressing the first piece 201 and the second piece 202 together. After the bottom surface of the bent portion 153 abuts against the upper surface of the second piece 202, the operator continues to press the operating portion 122 until the bottom surface of the body 102 contacts the upper surface of the second piece 202. Thus, the fastener 100 connects the first piece 201 and the second piece 202 in place.
[0038] Figure 3A is a perspective view of a second embodiment of a fastener assembly of the present application connected in place, Figure 3B Yes Figure 3A An exploded view of the fastener assembly is shown. Figure 3C Yes Figure 3A A cross-sectional view of a fastener assembly is shown. Figures 3A-3C The fastener assembly shown is Figures 2A-2CThe same parts of the fastener components shown are not repeated. Figures 3A-3C The fastener assembly shown is Figures 2A-2C The fastener assemblies shown differ primarily in that: Figures 3A-3C The fastener assembly shown has a thread 324 on its column 214, and a portion of the free end 134 of the fastener 100 for clamping the first piece 201 is in a spiral arrangement. The spiral arrangement can match the thread 324. In one embodiment, the thread 324 is an M6 thread, and the portion of the free end 134 is in a spiral arrangement that can match the M6 thread.
[0039] When the fastener 100 is required to connect the first piece 201 to the second piece 202, the operator can Figures 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 circles of the thread 324, and at least a portion of the free end 134 can abut against the thread 324.
[0040] 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 protection scope of the present application.
[0041] In the prior art, the fastener clamps the column of the first piece through the clamping arm, thereby connecting the first piece and the second piece. However, the clamping arm in the prior art is easy to break. The inventor of the present application found that since the fastening of the first piece and the second piece is maintained by the clamping arm, the first piece and the second piece are easy to move. In other words, the second piece is easy to move relative to the first piece in the horizontal direction (for example, along the radial direction of the body 102), resulting in the clamping arm being subjected to excessive force (for example, radial force along the radial direction of the body 102) and breaking.
[0042] 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 abutment arms 106. The abutment arms 106 can press the base 212 of the first piece 201 and the second piece 202, thereby hindering the relative movement of the first piece 201 and the second piece 202 in the horizontal direction (e.g., along the radial direction of the body 102), thereby preventing the clamping arms 104 from breaking.

In addition, the technical effects and / or technical problems described in this specification are exemplary rather than restrictive; so the disclosure in this specification may be used to solve other technical problems and have other technical effects and / or may solve other technical problems. Therefore, the examples of the embodiments of the present disclosure as stated above are intended to be illustrative rather than restrictive.

Therefore, the present disclosure is intended to include all known or earlier developed alternatives, modifications, changes, improvements and / or substantially equivalent solutions.
