Description

Technical Field

[0001] The utility model relates to the technical field of single-sided tooth lock washers, in particular to a special single-sided tooth lock washer for automobiles. Background Technique

[0002] The lock washer is an important fastener for cooperating with screws, etc. to fix mechanical components. Currently, the commonly used lock washers are generally in a flat state (with a hole in the middle).

[0003] For example, the published document with the application number 202220552989.7 discloses a lock washer with anti-slip teeth of different heights. This utility model is used in pairs of two. Between the washer body and the washer body, between the washer body and the nut and the fastened part, due to the anti-slip teeth on the washer body, it can increase the friction force between the washer and the bolt, washer, and fastened part, and the anti-slip teeth at the upper and lower ends of the two washer bodies can effectively embed between the fastened part and the nut, preventing loosening between the nut and the fastened part and achieving a better fastening effect for the fastened part. Based on the above, this utility model has a good application prospect. However, for this special single-sided tooth lock washer for automobiles, during use, the diameter of the hole in the middle of the washer is larger than the diameter of the nut. During use, the position of the washer may shift, resulting in the exposure of one side of the hole of the washer and being unable to be completely and effectively squeezed by the nut, making it difficult for the whole washer to fully fit on the surface of the fastener.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a special single-sided tooth lock washer for automobiles is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a special single-sided tooth lock washer for automobiles to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A special single-sided tooth lock washer for automobiles, including a washer body. Anti-slip teeth are evenly distributed and annularly arranged above the surface of the washer body. A connecting piece is fixedly installed inside the surface of the washer body, and a positioning ring is fixedly installed at one end of the connecting piece close to the middle of the washer body.

[0007] Preferably, the anti-slip teeth are obliquely arranged, and the thickness of the connecting piece is 2 mm - 4 mm.

[0008] Preferably, a rubber pad is fixedly installed below the surface of the washer body, and the rubber pad has its own elastic force and friction force.

[0009] Preferably, a thin film is coated below the surface of the rubber pad, and the thin film is a PET film.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Through the settings of the gasket body, anti-slip teeth, connecting piece and positioning ring, during use, the nut passes through the positioning ring, which can ensure the centered assembly of the gasket body and the nut, reduce the offset difference of the gasket body. At the same time, the anti-slip teeth can be embedded on the nut to prevent the nut from loosening and achieve a good fixing effect. After being pushed by the nut, the connecting piece will absorb stress and break after reverse screwing, so as to judge whether the nut at this place has been disassembled;

[0012] 2. Through the settings of the rubber pad and the film, the smooth surface of the film makes the whole gasket body and the nut easier to screw. When the film is close to the surface of the fastener, continuous rotation will cause frictional damage. At this time, the rubber pad is exposed and directly contacts the fastener, increasing the friction force of the contact surface and improving the stability of the gasket body fitting. And the elastic force of the rubber pad itself can also reduce vibration, further avoiding the loosening of the gasket body. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] As Figure 1 - Figure 3 shown, a special single-sided tooth anti-loosening gasket for automobiles includes a gasket body 1. Anti-slip teeth 2 are evenly distributed and annularly arranged above the surface of the gasket body 1. A connecting piece 3 is fixedly installed inside the surface of the gasket body 1, and a positioning ring 4 is fixedly installed at one end of the connecting piece 3 close to the middle of the gasket body 1.

[0019] By adopting the above technical solution, the nut passes through the positioning ring 4, which can ensure the centered assembly of the gasket body 1 and the nut, reducing the offset difference of the gasket body 1; the anti-slip teeth 2 can be embedded on the nut, preventing the nut from loosening and achieving a good fixing effect; after being pushed by the nut, the connecting piece 3 will absorb stress and break after reverse screwing, so as to determine whether the nut at this place has been disassembled.

[0020] Furthermore, the anti-slip teeth 2 are obliquely arranged, and the thickness of the connecting piece 3 is 2 mm - 4 mm.

[0021] By adopting the above technical solution, the obliquely arranged anti-slip teeth 2 can be well meshed with each other when the anti-slip teeth 2 of the two gasket bodies 1 are assembled oppositely; the extremely thin connecting piece 3 is more likely to break under force.

[0022] Furthermore, a rubber pad 5 is fixedly installed below the surface of the gasket body 1, and the rubber pad 5 has its own elastic force and frictional force.

[0023] By adopting the above technical solution, the rubber pad 5 increases the frictional force of the contact surface, improving the stability of the gasket body 1 in fitting, and the elastic force of the rubber pad 5 itself can also reduce vibration.

[0024] Furthermore, a thin film 6 is coated below the surface of the rubber pad 5, and the thin film 6 is a PET film.

[0025] By adopting the above technical solution, the smooth surface of the thin film 6 makes the entire gasket body 1 and the nut easier to screw.

[0026] Working principle: When using this special single-sided tooth anti-loosening gasket for automobiles, first:

[0027] Embodiment 1: During use, the nut passes through the positioning ring 4, which can ensure the centered assembly of the gasket body 1 and the nut, reducing the offset difference of the gasket body 1. At the same time, the anti-slip teeth 2 can be embedded on the nut, preventing the nut from loosening and achieving a good fixing effect. At the same time, after being pushed by the nut, the connecting piece 3 will absorb stress and break after reverse screwing, so as to determine whether the nut at this place has been disassembled. The smooth surface of the thin film 6 makes the entire gasket body 1 and the nut easier to screw. When the thin film 6 is in close contact with the surface of the fastener, continued rotation will cause frictional damage, and at this time, the rubber pad 5 is exposed and comes into direct contact with the fastener, increasing the frictional force of the contact surface and improving the stability of the gasket body 1 in fitting.

[0028] Embodiment 2: Two gasket bodies 1 are adopted, and the anti-slip tooth 2 surfaces are engaged with each other. At this time, the nut still passes through the positioning ring 4, which can ensure the centered assembly of the gasket body 1 and the nut, reducing the offset difference of the gasket body 1. However, the upper and lower sides are both changed to the film 6. The smooth surface of the film 6 makes the whole gasket body 1 and the nut easier to screw. When the film 6 is in close contact with the surface of the fastener and the nut, continued rotation will cause frictional damage. At this time, the rubber pad 5 is exposed and directly contacts the surfaces of the fastener and the nut to increase the screwing friction, and the elastic force is used to make the gasket body 1 and the nut more stable;

[0029] Embodiment 3: Two gasket bodies 1 are adopted, and the opposite sides of the anti-slip teeth 2 are attached. At this time, the nut still passes through the positioning ring 4, which can ensure the centered assembly of the gasket body 1 and the nut, reducing the offset difference of the gasket body 1. However, the upper and lower sides are changed to the anti-slip teeth 2. The anti-slip teeth 2 embedded in the fastener and the nut can prevent loosening between the nut and the fastened part, achieving a good fixing effect. And the two gasket bodies 1 are evenly attached with the rubber pad 5 to increase the friction between the gasket bodies 1 and avoid loosening of the gasket bodies 1. Moreover, the elastic force of the rubber pad 5 itself can also reduce vibration. This is the working principle of the special single-sided tooth anti-loosening gasket for automobiles.
