Description

Technical Field

[0001] This utility model relates to the field of rivets, and in particular to a rivet with a locking cap. Background Technology

[0002] Rivets are a common type of connector in the hardware industry. They can quickly and easily connect two parts together. However, traditional rivets are prone to loosening after riveting, and may even fall off in complex environments such as high vibration. Therefore, it is necessary to ensure that the rivet core does not loosen or fall off under low tension. Thus, it is essential to propose rivets with locking caps to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a rivet with a locking cap to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rivet with a locking cap, comprising a rivet body, a rivet locking cap, a rivet connector, and a rivet mounting component;

[0005] The rivet body includes a rivet head end, and a one-way limiting rod is provided near the rivet head end. A threaded rod is connected to the bottom of the one-way limiting rod. The rivet mounting part has a rivet through hole for the threaded rod to pass through. A locking cap mounting groove for assembling a rivet locking cap is provided at the upper end of the rivet through hole. The rivet connector has an internal threaded hole and is threaded to the bottom of the threaded rod. A second limiting extension is integrally formed at the bottom end of the rivet connector. The second limiting extension is in close contact with the lower surface of the rivet mounting part. A ratchet annular spring is provided inside the rivet locking cap. Several ratchet limiting strips are integrally formed on the outer wall of the one-way limiting rod.

[0006] Furthermore, each side of the second limiting extension is integrally formed with a second limiting pin, and the lower surface of the rivet mounting part is provided with a second positioning pin hole corresponding to the position of a pair of second limiting pins.

[0007] Furthermore, the top of the rivet locking cap is integrally formed with a first limiting extension, and each side of the first limiting extension is integrally formed with a first limiting pin. The upper surface of the rivet mounting part is provided with a first positioning pin hole corresponding to the position of a pair of first limiting pins.

[0008] Furthermore, the bottom of the rivet locking cap is integrally formed with an elastic expansion portion, which fits against the side wall of the locking cap mounting groove.

[0009] Furthermore, the elastic expansion part is an annular elastic body with a "V" shaped cross-section, and several deformation grooves are opened on the outer periphery of the elastic expansion part.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. During assembly, the rivet locking cap is first placed in the locking cap assembly slot, and the first limiting pins on both sides of the first limiting extension are respectively inserted into the first positioning pin holes on the upper surface of the rivet mounting part to limit the rivet locking cap and prevent rotation. Then, the rivet body is inserted through the rivet locking cap into the rivet through hole and threadedly connected to the bottom of the threaded rod through the rivet connector. The second limiting pins on both sides of the second limiting extension on the rivet connector are respectively inserted into the second positioning pin holes at the bottom of the rivet mounting part to limit the rivet connector and prevent rotation. Then, during the tightening process of the rivet body, the ratchet limiting strip on the one-way limiting rod cooperates with the ratchet ring spring group inside the rivet locking cap, so that the rivet body can only rotate and tighten in one direction, thereby effectively preventing the rivet body from turning backward and loosening.

[0012] 2. In the tightening process of the rivet body, the elastic expansion part is compressed, causing the outer edge of the elastic expansion part to push outward, so that the elastic expansion part fits against the side wall of the locking cap assembly groove, effectively preventing the rivet locking cap from falling out of the locking cap assembly groove, and further improving the assembly stability of the rivet body.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figures 1-5 The rivet with a locking cap shown includes a rivet body 1, a rivet locking cap 2, a rivet connector 3, and a rivet mounting component 4. The rivet body 1 includes a rivet head end 101, and a one-way limiting rod 102 is provided near the rivet head end 101. A threaded rod 103 is connected to the bottom of the one-way limiting rod 102. The rivet mounting component 4 has a rivet through hole 401 for the threaded rod 103 to pass through. The upper end of the rivet through hole 401 has a locking cap mounting groove 402 for assembling the rivet locking cap 2. The rivet connector 3 has an internal threaded hole. The bottom end of the rivet connector 3 is integrally formed with a second limiting extension 301, which is in close contact with the lower surface of the rivet mounting component 4. During assembly, the rivet locking cap 2 is first placed in the locking cap assembly slot 402, and then the rivet body 1 is inserted through the rivet locking cap 2 into the rivet through hole 401. The rivet connector 3 is then threadedly connected to the bottom of the threaded rod 103 to complete the installation.

[0022] The top of the rivet locking cap 2 is integrally formed with a first limiting extension 202, and each side of the first limiting extension 202 is integrally formed with a first limiting pin 203. The upper surface of the rivet mounting part 4 is provided with a first positioning pin hole 403 corresponding to the position of a pair of first limiting pins 203. When the rivet locking cap 2 is assembled in the locking cap assembly groove 402, the first limiting pins 203 on both sides of the first limiting extension 202 are respectively inserted into the first positioning pin holes 403 provided on the upper surface of the rivet mounting part 4 to limit the rivet locking cap 2 and prevent it from rotating. The rivet locking cap 2 has a ratchet ring spring assembly 201 inside, and the outer wall of the one-way limiting rod 102 is integrally formed with several ratchet limiting strips 1021. During the tightening process of the rivet body 1, the ratchet limiting strips 1021 on the one-way limiting rod 102 cooperate with the ratchet ring spring assembly 201 inside the rivet locking cap 2, so that the rivet body 1 can only rotate and tighten in one direction, thereby effectively preventing the rivet body 1 from turning in reverse and becoming loose.

[0023] Each side of the second limiting extension 301 is integrally formed with a second limiting pin 302. The lower surface of the rivet mounting part 4 is provided with a second positioning pin hole 404 corresponding to the position of a pair of second limiting pins 302. When the rivet connector 3 is assembled, the second limiting pins 302 on both sides of the second limiting extension 301 are respectively inserted into the second positioning pin holes 404 at the bottom of the rivet mounting part 4 to limit the rivet connector 3 and prevent it from rotating.

[0024] like Figure 5 As shown, the bottom of the rivet locking cap 2 is integrally formed with an elastic expansion part 204. The elastic expansion part 204 is an annular elastic body with a "V" shaped cross-section. During the tightening process of the rivet body 1, the elastic expansion part 204 is compressed, causing the outer edge of the elastic expansion part 204 to push outward, so that the elastic expansion part 204 fits against the side wall of the locking cap assembly groove 402, effectively preventing the rivet locking cap 2 from falling out of the locking cap assembly groove 402. Several deformation slots are opened on the outer periphery of the elastic expansion part 204, which is conducive to the deformation of the elastic expansion part 204 and makes the compression of the elastic expansion part 204 easier.

[0025] Working principle: During assembly, the rivet locking cap 2 is first placed in the locking cap assembly groove 402, and the first limiting pins 203 on both sides of the first limiting extension 202 are respectively inserted into the first positioning pin holes 403 provided on the upper surface of the rivet mounting part 4 to limit the rivet locking cap 2 and prevent rotation. Then, the rivet body 1 is inserted along the rivet locking cap 2 into the rivet through hole 401, and is threadedly connected to the bottom of the threaded rod part 103 through the rivet connector 3. The second limiting pins 302 on both sides of the upper second limiting extension 301 are respectively inserted into the second positioning pin holes 404 at the bottom of the rivet mounting part 4 to limit the rivet connector 3 and prevent rotation. Then, during the tightening process of the rivet body 1, the ratchet limiting strip 1021 on the one-way limiting rod 102 cooperates with the ratchet ring spring piece group 201 inside the rivet locking cap 2, so that the rivet body 1 can only be tightened by rotating in one direction, thereby effectively preventing the rivet body 1 from turning backward and becoming loose.
