Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts technology, specifically an anti-loosening screw fixing structure. Background Technology

[0002] Screws are tools that use the physical and mathematical principles of the inclined plane, circular rotation, and friction of an object to gradually tighten objects and machine parts.

[0003] In existing technologies, screws are often prone to loosening due to vibrations generated during equipment operation during installation, which reduces the effectiveness of screw fastening. This paper proposes an anti-loosening screw fastening structure to solve the above problems. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides an anti-loosening screw fixing structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening screw fixing structure, including a screw rod, a washer assembly sleeved on the screw rod, and an anti-loosening assembly slidably disposed inside the screw rod; wherein, the washer assembly includes a washer, an adhesive layer, and a first retaining tooth, the bottom of the washer is provided with an adhesive layer, and the top side of the washer is provided with a first retaining tooth in a circular array; the anti-loosening assembly includes an adsorption ring, a connecting rod, and a second retaining tooth, the bottom of the adsorption ring is provided with an adsorption ring in a circular array, and the bottom of the adsorption ring is fixedly connected with a second retaining tooth.

[0006] Preferably, a limiting ring is provided between the adsorption ring and the screw, and the inner ring array of the limiting ring has a groove adapted to the connecting rod. The limiting ring is an unclosed circular ring made of plastic.

[0007] Preferably, a magnet is provided on the bottom side of the adsorption ring.

[0008] Preferably, the first tooth is a right-angled trapezoidal structure, and the number of the first tooth and the second tooth are the same.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention prevents screws from loosening by using a combination of a screw, a washer assembly, an anti-loosening component, and a limiting ring. The screw is tightened into the installation position, and once tightened, the adhesive layer adheres to the installation surface. Pulling out the limiting ring disengages it from the connecting rod, causing the suction ring to move downwards and engage with the screw. The second locking tooth moves downwards and abuts against the right-angled edge of the first locking tooth, thus preventing the screw from rotating in the opposite direction and preventing it from loosening.

[0017] 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.

[0018] like Figures 1 to 5 As shown, this utility model provides an anti-loosening screw fixing structure, including a screw 1, a washer assembly 2 sleeved on the screw 1, and an anti-loosening assembly 3 slidably disposed inside the screw 1;

[0019] The gasket assembly 2 includes a gasket 201, an adhesive layer 202, and a first locking tooth 203. The adhesive layer 202 is provided at the bottom of the gasket 201, and the first locking tooth 203 is arranged in a ring array on the top side of the gasket 201. The anti-loosening assembly 3 includes an adsorption ring 301, a connecting rod 302, and a second locking tooth 303. The adsorption ring 301 is arranged in a ring array at the bottom, and the second locking tooth 303 is fixedly connected to the bottom of the adsorption ring 301.

[0020] As shown in the figure, a limiting ring 4 is engaged between the adsorption ring 301 and the screw 1. The inner ring array of the limiting ring 4 has slots that are compatible with the connecting rod 302. The limiting ring 4 is an unclosed circular ring made of plastic. The bottom side of the adsorption ring 301 is provided with a magnet. The first locking tooth 203 is a right-angled trapezoidal structure. The number of the first locking tooth 203 and the second locking tooth 303 is the same. The limiting ring 4 can separate the screw 1 from the adsorption ring 301, so that the second locking tooth 303 does not contact the first locking tooth 203 when the screw 1 is screwed. When it is necessary to remove the screw, the adsorption ring 301 is fastened so that the second locking tooth 303 does not abut against the first locking tooth 203, and then the screw 1 is rotated in the opposite direction to complete the removal.

[0021] Working principle and usage process of this utility model:

[0022] The gasket assembly 2 is fitted onto the screw 1. The screw 1 is screwed into the installation position. After tightening, the adhesive layer 202 is adhered and fixed to the installation object. The limiting ring 4 is pulled out, and the limiting ring 4 is disconnected from the connecting rod 302. The adsorption ring 301 moves downward and adsorbs and connects with the screw 1. The second retaining tooth 303 moves downward and abuts against the right angle side of the first retaining tooth 203, thereby preventing the screw 1 from rotating in the opposite direction and preventing the screw from loosening.
