The following describes the implementation of the present invention based on its overall structure.

[0038] Reference Figure 1 As shown, an embodiment of the present application provides a connecting fastener, comprising:

[0039] The clamping member 1 includes a first connecting portion 11 and a second connecting portion 12. The first connecting portion 11 has a protruding portion 111, and the second connecting portion 12 has an inner cavity 121. The protruding portion 111 is inserted into the inner cavity 121.

[0040] The second connecting portion 12 has a first side 122 and a second side 123 disposed opposite to each other. The first side 122 is recessed in a direction away from the first connecting portion 11 and is used to form a clamping groove 3 with a side wall of the first connecting portion 11 for fixing the mounting card 4.

[0041] The first connecting portion 11 is in contact with the second connecting portion 12, and the contact portion is movably connected, so that the first connecting portion 11 moves relative to the second connecting portion 12;

[0042] A connecting post 124 is fixedly provided on one side of the second connecting portion 12 away from the first connecting portion 11 , and the connecting post 124 passes through the plate 5 ;

[0043] Among them, the connecting column 124 includes a first column 1241 and a second column 1242 separated from each other, and a blocking portion 1243 is provided on the end side of the first column 1241 and the second column 1242 away from the first connecting portion 11. The blocking portion 1243 is in contact with the wall surface of the plate 5 away from the first connecting portion 11, and the side of the second connecting portion 12 facing the plate 5 is in contact with the plate 5 for connection with the plate 5.

[0044] according to Figure 1 and Figure 2 The technology in this field can set a clamping part 1 to fix the installation card 4, and then connect the clamping part 1 with the installation card 4 to the plate 5, thereby completing the mutual connection between the installation card 4 and the plate 5.

[0045] In the arrangement of the clip 1, the clip 1 may be formed by connecting the first connecting portion 11 and the second connecting portion 12. It is understood that a clamping groove 3 may be formed between the first connecting portion 11 and the second connecting portion 12 so that the mounting card 4 can be installed in the clamping groove 3.

[0046] Specifically, the connection between the first connecting portion 11 and the second connecting portion 12 is achieved by the cooperation between the protrusion 111 on the first connecting portion 11 and the inner cavity 121 of the second connecting portion 12. That is, the protrusion 111 extends into the inner cavity 121, the outer edge of the wall of the first connecting portion 11 and the outer edge of the wall of the second connecting portion 12 are in contact with each other, and the first connecting portion 11 and the second connecting portion 12 can slide relative to each other.

[0047] In the above process, the clamping slot 3 can be installed and removed from the mounting card 4 by the relative sliding between the first connecting portion 11 and the second connecting portion 12. That is, when the first connecting portion 11 slides relative to the second connecting portion 12, the clamping slot can be opened and locked.

[0048] Furthermore, a connecting column 124 is fixedly provided on one side of the second connecting portion 12 away from the first connecting portion 11. Those skilled in the art can realize the installation of the plate and the clamping member by setting the connecting column 124 to pass through the plate 5.

[0049] In the above arrangement, the connecting post 124 may specifically include a first column 1241 and a second column 1242 that are separated from each other, with a stopper 1243 provided at the ends of the first column 1241 and the second column 1242 that extend beyond the plate. After the connecting post 124 is connected to the plate 5, the stopper 1243 contacts the wall of the plate 5 away from the first connecting portion 11, and the second connecting portion 12 contacts the plate 5 on the side facing the plate 5.

[0050] With the above structure, the two opposite side surfaces of the plate 5 respectively contact the stop portion 1243 and the side wall of the second connection portion 12 , thereby achieving the fixation of the relative position of the plate 5 .

[0051] Through the above structure, the mounting card 4 and the plate 5 can be connected through the clamping member 1. The clamping member is connected to the mounting card 4 and the plate 5 respectively, and the mounting card 4 can be installed and removed by the relative movement of the first connecting portion 11 and the second connecting portion 12 in the clamping member.

[0052] Based on the relative movement between the first connecting portion 11 and the second connecting portion 12 described above, it can be understood that the sidewalls of the first connecting portion 11 and the sidewalls of the second connecting portion 12 contact each other and can slide relative to each other. Preferably, an elastic member 125 is installed on one side of the inner cavity 121, and the end of the elastic member 125 is fixedly mounted on the raised portion 111 to reset the first connecting portion 11 relative to the second connecting portion 12.

[0053] That is, an elastic member is provided between the side wall of the inner cavity and the raised portion. When the first connecting portion 11 and the second connecting portion 12 move to open the clamping groove, the raised portion 111 can compress the elastic member. When the force acting on the first connecting portion 11 disappears, the elastic member recovers its deformation, allowing the first connecting portion 11 to return to its original position.

[0054] Through the above arrangement, the movement between the first connecting member 11 and the second connecting member 12 can be restored in time, thereby achieving the closed state of the clamping groove in the absence of external force.

[0055] In one embodiment, the elastic member can be a spring, and a guide post is provided on the side of the protrusion 111 facing the spring. The guide post is passed through the interior of the spring, thereby ensuring that the spring can be stably compressed and restored.

[0056] In the above arrangement, the connecting column 124 passes through the plate 5 . Preferably, the plate 5 has a connecting hole 51 , and the middle position between the first column 1241 and the second column 1242 contacts the wall surface of the connecting hole 51 of the plate 5 .

[0057] In the structure where the connecting column 124 passes through the plate 5, specifically, the first column 1241 and the second column 1242 pass through the connecting hole 51. In the aforementioned structure, the middle position of the first column 1241 and the second column 1242 abuts against the wall surface of the connecting hole 51 of the plate 5, thereby making the connection between the second connecting portion 12 and the plate 5 more stable.

[0058] More preferably, the maximum distance between the first column 1241 and the second column 1242 is greater than the maximum diameter of the connection hole 51, and the first column 1241 and the second column 1242 are elastic. In other words, those skilled in the art can use elastic first and second columns 1241, 1242 and, during installation, bring them closer together so that the distance between them is less than the maximum diameter of the connection hole 51, allowing them to pass through the connection hole 51. After connection is complete, the first and second columns 1241, 1242 need to recover their deformation. Because the maximum distance between the first column 1241 and the second column 1242 is greater than the maximum aperture of the connecting hole 51 , the outer walls of the first column 1241 and the second column 1242 can contact the inner wall of the connecting hole 51 after the first column 1241 and the second column 1242 recover their deformation.

[0059] Preferably, the outer diameter of the stopper 1243 increases linearly from the end away from the plate 5 to the end contacting the plate 5, thereby making the process of drilling the connecting hole 51 in the first column 1241 and the second column 1242 more stable.

[0060] Specifically, the outer diameter of the end of the stopper 1243 away from the plate 5 is smaller than the outer diameter of the end that contacts the plate 5 , so that the end of the stopper 1243 away from the plate 5 can more easily pass through the connecting hole 51 .

[0061] More preferably, the connection between the first column 1241 and the second column 1242 is arc-shaped, thereby avoiding stress concentration between the first column 1241 and the second column 1242 when the first column 1241 and the second column 1242 are close to each other, thereby making the structure of the first column 1241 and the second column 1242 more stable.

[0062] Preferably, a limiting portion 126 that interferes with the plate 5 is fixedly connected to the side of the second connecting portion 12 close to the plate 5, and the limiting portion 126 is bent toward the position where the plate 5 is located and has elasticity. That is, a limiting portion that can interfere with the plate 5 is provided on the side of the second connecting portion 12 close to the plate 5. After the second connecting portion 12 is connected to the plate 5, the limiting portion 126 can interfere with the plate 5. From the above embodiment, it can be seen that after the second connecting portion 12 is connected to the plate 5, the blocking portion 1243 and the plate are in a positional relationship of interference. Therefore, the relative position of the plate 5 can be made more stable by the interference between the blocking portion 1243 and the plate, and the interference between the limiting portion 126 and the plate 5.

[0063] More preferably, the minimum distance between the limiting portion 126 and the stop portion 1243 is less than the thickness of the plate. This ensures that after the second connecting portion 12 is connected to the plate 5, the limiting portion 126 remains deformed. While remaining deformed, the limiting portion 126 can continue to have the force to recover the deformation, thereby pressing the plate 5 tightly.

[0064] In an optional embodiment, those skilled in the art may set a contact point on the side of the connecting column 124 corresponding to the limiting portion 126. Figure 9 When the stopper 126 contacts the plate 5, the contact point faces the plate and maintains contact with the plate. This allows the stopper 126 to be spaced away from the connecting post 124 to form a structure that presses against the plate, effectively making the installation position of the plate more stable.

[0065] In summary, the maximum distance between the first column 1241 and the second column 1242 is greater than the maximum aperture of the connecting hole 51, and the minimum distance between the limiting portion 126 and the blocking portion 1243 is less than the thickness of the plate, so that the relative position of the plate can be fixed from two directions perpendicular to each other.

[0066] In one embodiment, preferably, the second side 123 of the second connecting portion 12 extends toward the position of the plate to form a positioning column 127, and a positioning hole 52 is opened on the plate 5, and the positioning column 127 is inserted into the positioning hole 52 for positioning the installation of the clip 1.

[0067] With the above structure, the positioning post 127 and the connecting post 124 are arranged on the same side. When the connecting post 124 is connected to the connecting hole 51, the positioning post 127 is connected to the positioning hole 52. The above process can realize the positioning of the clamping member 1 during the connection process of the plate, thereby making the connection between the clamping member 1 and the plate 5 more convenient.

[0068] More preferably, the positioning post 127 is inserted into the positioning hole 52 and does not protrude from the side wall of the plate 5 away from the connector 1. This ensures that the side of the connected plate away from the connector 1 does not interfere with the installation of other parts.

[0069] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification.

[0070] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
