Description

Technical Field

[0001] This utility model relates to the field of gasket technology, and more specifically, to a gasket that is resistant to deformation and prevents loosening. Background Technology

[0002] Washers are parts placed between connected parts and nuts. There are many types of washers and they have a wide range of uses. Washers are also used in automobile assembly.

[0003] Currently, commonly used washers incorporate rubber components to improve their deformation resistance. However, under excessive compression, these rubber components lose their elasticity, thus reducing the washer's deformation resistance and ability to prevent loosening. For example, CN213628450U discloses a deformation-resistant washer comprising a structural body, which includes a washer and an elastic element. The washer has a first through hole at its center for connecting the elastic element, and the elastic element has a second through hole at its center. Both the upper and lower end faces of the washer have a set of internal grooves, with a gasket fixedly connected to each groove. The washer surface is coated with a wear-resistant coating. The elastic element is detachably connected to the washer. The elastic element includes a snap-fit ​​portion and elastic portions formed at the upper and lower ends of the snap-fit ​​portion. The snap-fit ​​portion is a hollow cylindrical structure with a diameter smaller than that of the elastic portions. An annular groove is formed between the elastic portions, with a groove diameter smaller than that of the first through hole.

[0004] As can be seen from the above-disclosed scheme, the gasket and the elastic element are made of rubber material. However, when the gasket is used, excessive compression of the gasket by the gasket will cause the gasket to break and be damaged. When the nut is tightened with the connected part, it will compress the elastic element. When the thickness of the elastic element is the same as the thickness of the gasket, the elastic element will lose its elasticity, thereby greatly reducing the anti-deformation and anti-loosening effect of the gasket. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a deformation-resistant and loosening-preventing washer. This deformation-resistant and loosening-preventing washer has a washer body made of elastic, compression-resistant rubber material. When subjected to compression, the first and second wear-resistant sheets come into contact with the extruded material, which not only improves the washer's anti-loosening effect but also increases its surface wear resistance. Furthermore, the support plate positioned between the first and second wear-resistant sheets ensures that the washer's elasticity is not affected when compressed, and also prevents the washer from being damaged by excessive compression, greatly improving the washer's deformation resistance.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A deformation-resistant and loosening-preventing washer includes a washer body with a central hole at its center. An anti-deformation component is fixedly integrated inside the washer body. The anti-deformation component includes a first wear-resistant sheet, a support plate fixedly connected to the surface of the first wear-resistant sheet, and a second wear-resistant sheet fixedly connected to the other end of the support plate. Both the first and second wear-resistant sheets have through holes at their centers, coaxial with the central hole. The washer body is made of elastic, compression-resistant rubber. When compressed, the first and second wear-resistant sheets contact the extruded material, improving both the anti-loosening effect and surface wear resistance. Furthermore, the support plate between the first and second wear-resistant sheets prevents damage from excessive compression, significantly enhancing the washer's deformation resistance.

[0008] Furthermore, the support plate is arc-shaped, and the support plate is arranged in a ring with equal spacing around the through hole. The support plate is made of elastic metal and is fixedly integrated inside the gasket body. When the support plate is squeezed by the first wear-resistant sheet and the second wear-resistant sheet, it has the function of compressive elasticity and can limit the spacing between the first wear-resistant sheet and the second wear-resistant sheet, thus preventing the gasket body from being excessively squeezed.

[0009] Furthermore, the support plate is provided with a first support part and a second support part at both ends, respectively. A first positioning block is fixedly connected to the surface of the first support part, and a second positioning block is fixedly connected to the surface of the second support part. The first support part is fixedly connected to the surface of the first wear-resistant sheet, and the second support part is fixedly connected to the surface of the second wear-resistant sheet, which can increase the connection firmness of the support plate.

[0010] Furthermore, both the first and second wear-resistant sheets are made of wear-resistant metal, and weight-reducing holes are opened on the surface of both the first and second wear-resistant sheets, which can reduce the amount of material used in the first and second wear-resistant sheets, reduce costs, and at the same time reduce the weight of the gasket.

[0011] Furthermore, both the first and second wear-resistant sheets have annularly spaced positioning grooves on their surfaces. The positioning grooves have a rectangular cross-sectional shape. The positioning grooves on the first and second wear-resistant sheets are respectively inserted into the first and second positioning blocks, which facilitates pre-positioning during the assembly of the support plate and improves the support stability of the support plate.

[0012] Furthermore, the surface of the washer body has buffer holes, which are distributed in a ring with equal spacing around the central hole. The buffer holes can prevent the washer body from bursting when it is squeezed, and can also reduce the amount of material used in the washer body, thus reducing costs.

[0013] Furthermore, the washer body is made of elastic, compression-resistant rubber, and grooves are provided on both surfaces of the washer body. The first wear-resistant plate and the second wear-resistant plate are both located in the grooves, so that when the washer body is compressed, the first wear-resistant plate and the second wear-resistant plate protrude and contact the nut and the connected parts.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) The gasket body of this solution is made of elastic and extrusion-resistant rubber material. When it is compressed, the first wear-resistant sheet and the second wear-resistant sheet come into contact with the extruded material, which not only improves the anti-loosening effect of the gasket, but also increases the wear resistance of its surface.

[0016] (2) The support plate set between the first wear-resistant plate and the second wear-resistant plate in this solution will not affect the elastic effect of the gasket when the gasket is squeezed, and at the same time, it can avoid the gasket being damaged by excessive compression, which greatly improves the deformation resistance of the gasket.

[0024] 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.

[0025] Example 1: Please refer to Figure 1-5 A deformation-resistant and loosening-preventing washer includes a washer body 1 with a central hole 11 for fitting a screw, facilitating the washer's fit on the screw surface. An anti-deformation component 2 is fixedly integrated inside the washer body 1. When the two ends of the washer body 1 are compressed and contract towards the center, a first wear-resistant plate 3 and a second wear-resistant plate 4 protrude from the surfaces of the two ends of the washer body 1, thus contacting the compressed material and preventing damage to the surfaces of the two ends of the washer body 1, extending its service life. The anti-deformation component 2 includes a first wear-resistant plate 3, with a support plate 5 fixedly connected to its surface. The support plate 5 prevents excessive compression of the first wear-resistant plate 3 and the second wear-resistant plate 4 towards the center. The support plate 5 is arc-shaped and forms a ring around a through hole 31. The support plate 5 is made of elastic metal and is fixedly integrated inside the washer body 1. When the support plate 5 is squeezed by the first wear-resistant plate 3 and the second wear-resistant plate 4, it has the function of compressive elasticity and can limit the spacing between the first wear-resistant plate 3 and the second wear-resistant plate 4 to avoid excessive compression of the washer body 1. The other end of the support plate 5 is fixedly connected to the second wear-resistant plate 4. Both the first wear-resistant plate 3 and the second wear-resistant plate 4 are made of wear-resistant metal. The surfaces of the first wear-resistant plate 3 and the second wear-resistant plate 4 are provided with weight-reducing holes 32, which can reduce the amount of material used for the first wear-resistant plate 3 and the second wear-resistant plate 4, reduce costs, and reduce the weight of the washer. The center positions of the first wear-resistant plate 3 and the second wear-resistant plate 4 are provided with through holes 31, which are coaxial with the center hole 11.

[0026] The support plate 5 has a first support part 51 and a second support part 53 at both ends. A first positioning block 52 is fixedly connected to the surface of the first support part 51, and a second positioning block 54 is fixedly connected to the surface of the second support part 53. The first support part 51 is fixedly connected to the surface of the first wear-resistant sheet 3, and the second support part 53 is fixedly connected to the surface of the second wear-resistant sheet 4, which can increase the connection firmness of the support plate 5. The surfaces of the first wear-resistant sheet 3 and the second wear-resistant sheet 4 are both provided with annularly spaced positioning grooves 33. The cross-sectional shape of the positioning grooves 33 is rectangular. The positioning grooves 33 of the first wear-resistant sheet 3 and the second wear-resistant sheet 4 are respectively inserted into the first positioning block 52 and the second positioning block 54, which facilitates the pre-positioning of the support plate 5 during assembly and improves the support stability of the support plate 5.

[0027] The surface of the washer body 1 has buffer holes 12. The buffer holes 12 are distributed in a ring with equal spacing around the central hole 11. The buffer holes 12 can prevent the washer body 1 from bursting when it is squeezed, and can also reduce the amount of material used in the washer body 1, thus reducing the cost. The washer body 1 is made of elastic compression-resistant rubber. Both surfaces of the washer body 1 are provided with grooves. The first wear-resistant plate 3 and the second wear-resistant plate 4 are both located in the grooves, so that when the washer body 1 is squeezed, the first wear-resistant plate 3 and the second wear-resistant plate 4 can protrude and contact the nut and the connected parts.

[0028] When using this anti-deformation and anti-loosening washer, first place the washer on the screw, then tighten the nut clockwise. The tightening of the nut first compresses one end face of the washer body 1, while the other end face of the washer contacts and is compressed against the connected component, causing damage to both ends of the washer body 1. At this time, the surfaces of the nut and the connected component contact the surfaces of the first wear-resistant plate 3 and the second wear-resistant plate 4, respectively. As the nut continues to tighten, the first wear-resistant plate 3 and the second wear-resistant plate 4 are pressed towards the center of the washer. Simultaneously, the support plate 5 is compressed and bent, limiting the spacing between the first wear-resistant plate 3 and the second wear-resistant plate 4, preventing the washer from shifting. The washer body 1 is compressed and generates compressive elasticity to prevent the nut from loosening. The washer body 1 is made of elastic and compression-resistant rubber. When compressed, the first wear-resistant plate 3 and the second wear-resistant plate 4 come into contact with the extruded material, which not only improves the anti-loosening effect of the washer, but also increases the wear resistance of its surface. Furthermore, the support plate 5 set between the first wear-resistant plate 3 and the second wear-resistant plate 4 ensures that the elastic effect of the washer is not affected when the washer is compressed, and also prevents the washer from being damaged by excessive compression, thus greatly improving the deformation resistance of the washer.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
