[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0032] Please see Figure 1-3 A type of anti-loosening screw includes a screw assembly 1, an anti-loosening component 2 and a buffer component 3 mounted on the screw assembly 1. The cooperation between the anti-loosening component 2 and the buffer component 3 on the screw assembly 1 facilitates buffering and shock absorption of the screw, thereby preventing the screw from loosening and falling off. The screw assembly 1 includes a screw body 9, and a screwdriver bit 10 is fixedly connected to the top outer wall of the screw body 9. The screwdriver bit 10 is set to facilitate blocking the installation of the screw body 9. The anti-loosening component 2 includes an anti-loosening sleeve 4 sleeved on the screw body 9. The anti-slip sleeve 4 is made of aluminum alloy, which improves the stability of the anti-slip sleeve 4. The inner wall of the anti-loosening sleeve 4 is fixedly connected with multiple equally spaced anti-slip teeth 5. The anti-slip teeth 5 in the anti-loosening sleeve 4 facilitates fixing the anti-loosening sleeve 4 to the screw body 9 and assists in fixing the anti-loosening sleeve 4 to the screw body 9.
[0033] In use, the anti-loosening component 2 is provided on the screw assembly 1, thereby improving the stability of screw fixing. The buffer component 3 is provided to buffer the vibration of the screw, thereby preventing the screw from falling off due to vibration. The anti-slip teeth 5 in the anti-loosening sleeve 4 make it easy to fix it on the screw body 9.
[0034] Reference Figure 1-2The anti-loosening sleeve 4 has a conical structure, and the outer wall of the anti-loosening sleeve 4 is provided with external threads 6. The conical structure of the anti-loosening sleeve 4 facilitates the fixing of the auxiliary screw. By setting the anti-loosening sleeve 4 to a conical structure, it is convenient to connect the anti-loosening sleeve 4 to the fixed part. The external threads 6 facilitate the fixing of the fixed part. The external threads 6 of the anti-loosening sleeve 4 facilitate direct connection with the fixed part, thereby improving the stability of the screw.
[0035] Reference Figure 3 The buffer assembly 3 includes a mounting sleeve 7 that is fitted onto the screw body 9, and a buffer rubber sleeve 8 is fixedly connected to the bottom outer wall of the mounting sleeve 7. The buffer rubber sleeve 8 is designed to facilitate the fixing of the screw. The buffer rubber sleeve 8 is fitted onto the outer wall of the screw body 9. The buffer rubber sleeve 8 in the buffer assembly 3 facilitates the buffering of the screw body 9. The mounting sleeve 7 is designed to facilitate the fixed installation of the buffer rubber sleeve 8.
[0036] Reference Figure 4-5 The bottom outer wall of the bit 10 has an annular groove 11, and the inner wall of the annular groove 11 is slidably connected to a clamping ring 13. The opening of the annular groove 11 facilitates the installation of the clamping ring 13. The clamping ring 13 is slidably connected in the annular groove 11. The clamping ring 13 slidably connected on the bit 10 facilitates the buffer assembly 3 for buffering assistance. The top of the bit 10 has a cross groove to facilitate the disassembly and assembly of the screw.
[0037] Reference Figure 5-6 Multiple support components 12 are fixedly connected to the top inner wall of the annular groove 11, and the support component 12 includes a support seat 14 fixedly connected to the inner wall of the annular groove 11. The support seat 14 is provided to provide elastic support for the clamping ring 13, and the support component 12 is provided to provide support for the clamping ring 13.
[0038] Reference Figure 6The support base 14 has a rectangular groove on its bottom outer wall, and the same mounting rod 15 is fixedly connected to the inner walls of both sides of the rectangular groove. The rectangular groove in the support base 14 facilitates the fixed installation of the mounting rod 15. Two symmetrically arranged sliding sleeves 16 are slidably connected to the outer wall of the mounting rod 15, and the outer walls of the two sliding sleeves 16 are rotatably connected to connecting plates 18. The mounting rod 15 facilitates the sliding installation of the two sliding sleeves 16. When the sliding sleeves 16 move, they directly drive the connecting plates 18 to move. One end of each of the two connecting plates 18 is rotatably connected to the clamping ring 13. Two symmetrically arranged springs 17 are sleeved on the outer wall of the mounting rod 15. At the midpoint of the mounting rod 15 The fixed connection has a limiting sleeve, which separates the two springs 17 to prevent them from interfering with each other. This ensures that the clamping ring 13 provides stable support for the buffer assembly 3. The springs 17 push the two sliding sleeves 16 to move apart, which facilitates the clamping ring 13 to press down. The springs 17 on the mounting rod 15 provide support for the sliding sleeves 16, thus facilitating the buffering of the screw's vibration. When the anti-loosening assembly 2 is installed, the clamping ring 13 provides clamping support for the buffer assembly 3. The springs 17 in the support assembly 12 drive the two sliding sleeves 16 to move apart, thus facilitating stable support for the buffer assembly 3.
[0039] The implementation principle of this application is as follows: In use, the buffer assembly 3 is first sleeved on the screw body 9, and then the anti-loosening sleeve 4 is screwed onto the outer wall of the screw body 9. The anti-slip teeth 5 in the anti-loosening sleeve 4 cooperate with the thread groove on the screw body 9, so as to facilitate the fixation of the anti-loosening sleeve 4 on the screw body 9. When the anti-loosening sleeve 4 is screwed onto the outer wall of the screw body 9, it will press the clamping ring 13 through the buffer assembly 3. When the clamping ring 13 is squeezed, it directly pushes the two sliding sleeves 16 to move towards each other through the connecting plate 18. When the two sliding sleeves 16 move towards each other, they directly compress the spring 17, so as to facilitate the buffering of the screw from vibration.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
