Description

Technical Field

[0001] The utility model belongs to the technical field of rivet nuts, and in particular relates to an anti-loosening rivet nut. Background Art

[0002] The development of rivet nuts is to solve the problem of installing parts on thin plates. Rivet nuts combine the functions of rivets and nuts. When assembling, do not tap the internal threads or weld the nuts. Riveting is firm, convenient and fast. As a new type of fastener, rivet nuts are widely used in the assembly of various products. In order to solve the problem of loose assembly caused by vibration and impact after the rivet nut is assembled, a locking part needs to be designed on the rivet nut product so that the bolt will not loosen even if it encounters vibration and impact after being screwed into the rivet nut, so as to ensure that there will be no safety accidents in the equipment.

[0003] The Chinese utility model patent with publication number CN214578250U discloses an anti-loosening rivet nut structure. Through the cooperation of the rivet nut, the screw, the annular groove and the nylon locking ring, when the screw is screwed into the nylon locking ring, a thread is formed on the nylon locking ring and tightly engaged with the screw thread, eliminating the gap between the screw and the rivet nut and increasing the friction between the thread contact surfaces. In addition, nylon has good elasticity and mechanical properties, and is fatigue-resistant and shock-absorbing. Even under the impact of lateral loads, the screw thread and the screw thread extruded on the nylon locking ring are tightly engaged, which controls the swing of the screw and prevents its relative movement. The device has the characteristics of simple structure and improved anti-seismic and anti-loosening performance. However, the device still has some other problems. For example, the device only adds a nylon locking ring to the connection between the screw and the rivet nut to increase the friction, but this method still has a certain possibility of loosening the connection between the rivet nut and the screw.

[0054] Embodiment 3:

[0055] This embodiment provides an anti-loosening rivet nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] like Figure 1-Figure 5 As shown, in this embodiment, the locking assembly 370 further includes:

[0057] A second spring 371, one end of which is fixedly connected to the bottom of the groove 110;

[0058] A fixing plate 372 fixedly connected to the other end of the second spring 371;

[0059] The clamping block 373 is disposed on the fixing plate 372 .

[0060] In the present technical solution, in order to enable the locking assembly 370 to be locked with the rivet nut body 100 and the screw rod 200, one end of a second spring 371 is fixedly connected to the grooves 110 on both sides of the fixing block 310, and the other end of the second spring 371 is fixedly connected to a fixing plate 372, one side of the fixing plate 372 is arranged on the lower side of the baffle 360, and a clamping block 373 is arranged on the upper surface of the other side of the fixing plate 372.

[0064] In the present technical solution, in order to enable the screw rod 200 and the opening 220 on the rivet nut body 100 to be used in conjunction with the clamping block 373, the size and shape of the opening 220 are set to match the size and shape of the clamping block 373, so that after the clamping block 373 is inserted into the interior of the opening 220, the screw rod 200 and the rivet nut body 100 will not be loose because the opening 220 is clamped by the clamping block 373.

[0065] Embodiment 5:

[0066] This embodiment provides an anti-loosening rivet nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] like Figure 1-Figure 5 As shown, in this embodiment, the control block 340 is designed as a frustum.

[0068] In the present technical solution, in order to facilitate the baffles 360 on both sides of the control block 340 to retract toward the middle, the control console is set to be a truncated cone shape. In this way, when the control block 340 is pressed down by the screw 200, the control block 340 can make the baffles 360 on both sides move closer to the middle so that the fixed block 310 blocked by the baffle 360 ​​loses its blocking force, thereby allowing the blocking block 373 to be stuck in the opening 220.

[0069] Embodiment 6:

[0070] This embodiment provides an anti-loosening rivet nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] like Figure 1-Figure 5 As shown, in this embodiment, the baffles 360 on the left and right sides of the control block 340 are connected by a spring rope 361.

When the control block 340 is pressed by the screw 200, because the control block 340 in the middle of the baffle plates 360 becomes smaller, the spring ropes 361 pull the two baffle plates 360 toward the center, thereby removing the force that blocks the fixing plate 372 from being bounced upward by the spring.

[0073] Embodiment 7:

[0074] This embodiment provides an anti-loosening rivet nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] like Figure 1-Figure 5 As shown, in this embodiment, the baffle 360 ​​is telescopically installed above the fixing block 310 .

[0076] In the present technical solution, in order to enable the baffle 360 ​​to change its position, the baffle 360 ​​is configured to be retractable, which facilitates the control of the state of the fixed plate 372. When the baffle 360 ​​is extended to the top of the fixed plate 372, the fixed plate 372 is compressed by the baffle 360. When the baffle 360 ​​is shortened to the inside of the control block 340, the fixed plate 372 is bounced up by the spring.

[0077] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
