Description

Technical Field

[0001] The utility model relates to the field of rubber gaskets, in particular to a waterproof high-density polymerized automobile shock absorber rubber gasket. Background Art

[0002] Automobile shock absorber washers play an important role in vehicles. They are mainly used to reduce vibrations caused by uneven road surfaces and improve the stability and comfort of the vehicle.

[0003] For example, a waterproof high-density polymer automobile shock absorber rubber gasket disclosed in a Chinese utility model with publication number CN218118577U includes a bottom ring, an outer ring is fixedly connected to the outer side of the bottom ring, and the vertical section of the outer ring is semicircular; since the end face of the rubber gasket in the utility model is flat, the moisture on it is not easy to drain away, so the moisture on the shock absorber is easy to gather on the gasket and penetrate into the shock absorber due to vibration.

[0004] Therefore, it is necessary to design a waterproof high-density polymer automobile shock absorber rubber gasket to alleviate the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a waterproof high-density polymer automobile shock absorber rubber gasket, which is used to overcome the above-mentioned defects in the prior art.

[0006] According to the utility model, a waterproof high-density polymer automobile shock absorber rubber gasket includes a gasket body, a plurality of circles of outward ridges are arranged on the outer periphery of the gasket body, the cross-section of the ridges is triangular, water guide edges are fixedly arranged on the upper and lower end surfaces of the gasket body, a drainage thin layer is fixedly arranged between the water guide edge and the adjacent ridges, and the drainage thin layer is inclined from the inside to the outside toward the ridge direction.

[0007] Through the above technical solution, the moisture on the automobile shock absorber flows along the water guiding edge to the drainage thin layer, and the drainage thin layer vibrates with the vibration of the shock absorber. Since the thickness of the drainage thin layer is thin, the vibration amplitude of the drainage thin layer is large, and the moisture on the upper side of the drainage thin layer is quickly drained along its surface, reducing the moisture accumulation and infiltrating into the shock absorber along the gap between the gasket and the shock absorber.

[0008] The utility model is further configured as follows: the surface of the drainage thin layer is coated with a hydrophobic layer.

[0009] Through the above technical solution, the hydrophobic layer can accelerate the flow of water in the drainage thin layer, which is conducive to the drainage of water from the drainage thin layer.

[0010] The utility model is further configured as follows: the upper and lower ends of the water guide edge are inclined surfaces inclined from the inside to the outside in the direction of the drainage thin layer, and the inner edge of the drainage thin layer is fixed at the outer edge of the inclined surface at the end of the water guide edge.

[0011] Through the above technical solution, the moisture on the shock-absorbing column can easily flow to the drainage thin layer through the end of the water-guiding edge and be discharged through the drainage thin layer.

[0012] The utility model is further configured as follows: support rings are fixed to both upper and lower end surfaces of the gasket body, the height of the support ring is higher than the height of the water guide edge, a plurality of drainage openings are opened in the support ring, and a side wall of the drainage opening close to the gasket body is flush with the outer edge and the inner edge of the convex ridge.

[0013] Through the above technical solution, the support ring abuts against the shock absorber, which can reduce the shock absorber from squeezing the drainage thin layer and causing it to rupture.

[0014] The utility model is further configured as follows: the support ring is made of high-density polymer rubber.

[0015] Through the above technical solution, the support ring made of high-density polymer rubber has high strength and high wear resistance, ensuring the support strength of the support ring.

[0016] The utility model is further configured as follows: the gasket body is made of styrene-butadiene rubber, and the surface is coated with a hydrophobic layer.

[0017] Through the above technical solution, the gasket body made of styrene-butadiene rubber has good wear resistance and crack resistance, and can resist various impacts and frictions on the road surface.

[0018] The utility model is further configured as follows: a plurality of cavities located inside the convex ridges are provided in the gasket body.

[0019] Through the above technical solution, the opening of the cavity enables the gasket body to have a better deformation amount, thereby ensuring the elasticity of the gasket body.

[0020] The beneficial effects of the utility model are as follows: moisture on the automobile shock absorber flows along the water guiding edge to the drainage thin layer, and the drainage thin layer vibrates with the vibration of the shock absorber. Since the thickness of the drainage thin layer is thin, the vibration amplitude of the drainage thin layer is large, so the moisture on the upper side of the drainage thin layer is quickly drained along its surface, reducing the accumulation of moisture and infiltrating into the shock absorber along the gap between the gasket and the shock absorber. By abutting the support ring with the shock absorber, the shock absorber can be reduced from squeezing the drainage thin layer and causing it to rupture. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] An embodiment of the utility model:

[0030] Reference Figure 1-Figure 3The utility model provides a waterproof high-density polymer automobile shock absorber rubber gasket, including a gasket body 10, the outer periphery of the gasket body 10 is provided with a plurality of outward convex ridges, the cross section of the convex ridge is triangular, the upper and lower end surfaces of the gasket body 10 are fixed with water guide edges 11, and a drainage thin layer 12 is fixed between the water guide edge 11 and the adjacent convex ridges. The drainage thin layer 12 is inclined from the inside to the outside toward the convex ridge. The surface of the drainage thin layer 12 is coated with fluorocarbon compounds to form a hydrophobic layer, which effectively resists the erosion of water, oil and other liquids. The fluorocarbon coating also has good wear resistance and scratch resistance, and can protect the surface of the drainage thin layer 12 from mechanical damage. The upper and lower ends of the water edge 11 are inclined surfaces inclined from the inside to the outside toward the drainage thin layer 12. The inner edge of the drainage thin layer 12 is fixed at the outer edge of the inclined surface at the end of the water guide edge 11. Support rings 13 are fixed to the upper and lower end surfaces of the gasket body 10. The height of the support ring 13 is higher than the height of the water guide edge 11. A number of drainage ports 15 are opened in the support ring 13. The side wall of the drainage port 15 close to the gasket body 10 is flush with the outer edge 23 and the inner edge of the convex ridge. The support ring 13 is made of high-density polymer rubber, and the gasket body 10 is made of styrene-butadiene rubber. The surface is coated with a hydrophobic layer. The gasket body 10 is provided with a number of circles of cavities 14 located on the inner side of the convex ridge.

[0031] During operation, the gasket vibrates due to the vibration of the shock absorber, which in turn causes the drainage layer 12 to vibrate greatly. The moisture on the surface of the drainage layer 12 flows along its surface to the drain port 15, and is discharged along the ridge surface through the drain port 15, thereby reducing the accumulation of moisture on the surface of the drainage layer 12, and further reducing the moisture from penetrating into the shock absorber due to vibration.

[0032] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
