[0002] A rubber sealing ring is a common sealing structure connected to a shaft. The rubber sealing ring of the prior art is ring-shaped. Although it can meet the general use requirements, its dust-proof performance is relatively limited, so some dust and other impurities can easily enter the interior, affecting the stability of the internal structure. Moreover, it is sealed through a single extrusion, and the sealing effect is also limited, making it difficult to meet market demand. Utility Model Content

[0003] The purpose of the utility model is to provide a dustproof rubber ring with reasonable structure and strong sealing performance.

[0004] The technical solution for achieving the purpose of the utility model is a dustproof rubber ring, comprising a rubber ring body, wherein the inner ring of the rubber ring body is integrally formed with a plurality of convex rings with a V-shaped cross section;

[0005] Both ends of the rubber ring body are inlaid with circular ribs;

[0006] A cylindrical retaining ring is integrally formed on the inner ring edges of the two convex rings in the middle, and a buffer gap is provided between the cylindrical retaining ring and the inner wall of the rubber ring body.

[0007] It is further preferred that the number of the convex rings is four, and the cylindrical retaining ring is located between the two convex rings in the middle.

[0008] Further preferably, both ends of the rubber ring body are provided with an annular groove;

[0009] The annular rib is located between the annular groove and the inner cavity of the rubber ring body.

[0010] More preferably, the rubber ring body is a rubber structure.

[0011] More preferably, the annular ribs are plastic ribs or rubber ribs.

[0012] Further preferably, the outer surface of the rubber ring body is provided with a wear-resistant layer.

[0013] The utility model has positive effects: the structure of the utility model is reasonably set up, and it is provided with several convex rings with V-shaped cross-sections, and circular ribs are inlaid at both ends of the rubber ring body, and there is a cylindrical retaining ring between the two convex rings in the middle. Therefore, during installation, not only can the convex rings at both ends be used for retaining and sealing, but also the cylindrical retaining ring can be used for attachment to achieve multi-point retaining and sealing, which is beneficial to improving the sealing and dustproof performance and improving the stability of use.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example

[0020] See Figures 1 to 2 As shown, a dustproof rubber ring comprises a rubber ring body 1, the inner ring of which is integrally formed with several V-shaped raised rings 2. In this embodiment, the rubber ring body is a rubber structure. The raised rings allow it to abut against the surface of a component such as a shaft during connection, achieving multi-point abutment and improving dustproof sealing performance. Furthermore, circular ribs 3 are embedded at both ends of the rubber ring body; these ribs can be plastic or rubber. These ribs ensure a stable connection between the two ends of the rubber ring body and prevent deformation.

[0021] Furthermore, in actual use, a cylindrical retaining ring 4 is integrally formed on the inner ring edge of the two central convex rings, with a buffer gap 5 between the cylindrical retaining ring and the inner wall of the rubber ring body. The cylindrical retaining ring can increase the connection contact area, and the buffer gap is provided in the middle to facilitate buffering, ensure the effectiveness of the retaining, and effectively improve dustproof performance.

[0022] In this embodiment, the number of the protruding rings is four, and the cylindrical retaining ring is located between the two protruding rings in the middle.

[0023] In this embodiment, annular grooves 6 are formed at both ends of the rubber ring body; the annular ribs are located between the annular grooves and the inner cavity of the rubber ring body. The annular grooves provide a slight cushioning effect, improving stability and reliability. The outer surface of the rubber ring body is provided with a wear-resistant layer 7. This structure improves wear resistance. The wear-resistant layer is prior art, specifically described in Chinese Patent No. 202322753596.X, and therefore is not described in detail.

[0024] The utility model has positive effects: the structure of the utility model is reasonably set up, and it is provided with several convex rings with V-shaped cross-sections, and circular ribs are inlaid at both ends of the rubber ring body, and there is a cylindrical retaining ring between the two convex rings in the middle. Therefore, during installation, not only can the convex rings at both ends be used for retaining and sealing, but also the cylindrical retaining ring can be used for attachment to achieve multi-point retaining and sealing, which is beneficial to improving the sealing and dustproof performance and improving the stability of use.

[0025] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0026] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
