[0022] Example 1:

[0023] like Figures 1 to 4 As shown, a car anti-loosening nut is applied to a nut body 1. The top surface of the nut body 1 is connected to a braking mechanism 3 through a positioning mechanism 2, and the braking mechanism 3 is symmetrically arranged on the top surface of the nut body 1. A reinforcement mechanism 4 is arranged on the opposite side of the braking mechanism 3. Adjustment mechanisms 5 are symmetrically arranged on both sides of the reinforcement mechanism 4 located on the right side, and an engaging mechanism 6 is arranged on the left side of the adjusting mechanism 5. Connecting mechanisms 7 are symmetrically arranged on both sides of the reinforcement mechanism 4 located on the left side, and the connecting mechanism 7 is connected to the engaging mechanism 6.

[0024] In this embodiment, first, the anti-loosening structure in this case is connected to the nut body 1 by snapping in the positioning mechanism 2, which is convenient for assembly and disassembly. Then, the components in the braking mechanism 3 are adjusted, and the reinforcement mechanism 4 is fitted to the threaded rod. Then, the components in the adjusting mechanism 5 are extended to the connecting mechanism 7 with the engaging mechanism 6, so that multiple reinforcement mechanisms 4 fitted to the threaded rod are limited on the threaded rod. After the connection between the nut body 1 and the threaded rod, a structure for stabilizing and loosening the threaded rod and the nut body 1 is added, which improves practicality.

[0025] Example 2:

[0026] Furthermore, Figures 1 to 4 As shown, the positioning mechanism 2 includes a positioning block 8 and a positioning groove 9. The positioning groove 9 is symmetrically dug on the left and right sides of the top surface of the nut body 1. The positioning block 8 is engaged with the positioning groove 9.

[0027] The brake mechanism 3 includes a recessed frame 10, a brake shaft 11 and a brake rod 12. The recessed frame 10 is arranged in the middle of the top surface of the positioning block 8. The brake shaft 11 is arranged on the front surface of the inner cavity of the recessed frame 10, and the brake rod 12 is sleeved on the outer wall of the brake shaft 11.

[0028] The reinforcement mechanism 4 includes a reinforcement block 13 and a reinforcement opening 14. The reinforcement block 13 is arranged on the opposite side of the brake rod 12, and a reinforcement opening 14 is dug on one side of the reinforcement block.

[0029] In this embodiment, the brake rod 12 sleeved on the outer wall of the brake shaft 11 is adjusted with the reinforcement block 13 thereon, so that the reinforcement opening 14 dug in the reinforcement block 13 fits with the threaded rod.

[0030] Example 3:

[0031] Furthermore, Figures 1 to 4 As shown, the adjustment mechanism 5 includes a mounting block 15, an adjustment shaft 16, a sleeve 17, a spring 18 and an adjustment plate 19. The mounting block 15 is arranged on the front and rear sides of the reinforcement block located on the right side. The adjustment shafts 16 are symmetrically arranged on the upper and lower sides of the mounting block 15. The outer wall of the adjustment shaft 16 is sleeved with a sleeve 17. The left side of the sleeve 17 is fixedly connected to the spring 18, and the left side of the spring 18 is connected to the adjustment plate 19.

[0032] The engaging mechanism 6 includes an engaging rod 20 and an engaging block 21. The engaging rod 20 is fixedly arranged on the left side of the adjustment plate 19, and the rear surface of the engaging rod 20 is fixedly connected to the engaging block 21.

The connection block 22 is symmetrically arranged on the front and rear sides of the reinforcement block 13 on the left side. The connection opening 23 is dug on one side of the connection block 22, and the engaging block 21 extends into the connection opening 23.

[0034] In this embodiment, the adjusting plate 19 is pulled, and the pulling of the adjusting plate 19 causes the spring 18 connected to its right side to deform, and the adjusting plate 19 moves to the left with the engaging rod 20 fixedly connected on the left side, so that the engaging block 21 fixedly connected to the rear surface of the engaging rod 20 extends into the connecting port 23, and the adjusting plate 19 is loosened to reset the spring 18. Under this operation, the engaging block 21 abuts against the connecting port 23, and multiple fixed blocks 13 are limited on the surface of the threaded rod, providing a loosening effect for the connection between the nut body 1 and the threaded rod.

[0035] In summary, with the help of the above-mentioned technical solution of the present invention, when this device is in use, the positioning block 8 is first engaged into the positioning groove 9, so that the positioning block 8 and the anti-loosening structure on it are connected with the nut body 1, and then the brake rod 12 sleeved on the outer wall of the brake shaft 11 is adjusted with the reinforcement block 13 thereon, so that the reinforcement opening 14 dug in the reinforcement block 13 is fitted with the threaded rod, and then the adjusting plate 19 is pulled. The pulling of the adjusting plate 19 causes the spring 18 connected to its right side to deform, and the adjusting plate 19 moves to the left with the fixed engagement rod 20 on the left side, so that the engagement block 21 fixedly connected to the rear surface of the engagement rod 20 extends into the connecting opening 23, and the adjusting plate 19 is released to reset the spring 18. Under this operation, the engagement block 21 abuts against the connecting opening 23, and multiple fixed blocks 13 are limited on the surface of the threaded rod, providing a loosening effect for the connection between the nut body 1 and the threaded rod.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
