[0017] 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.

[0018] Example

[0019] See Figures 1 to 2 As shown, a shock-absorbing rubber ring comprises an outer ring body 1 and an inner ring body 2. The outer ring body has a truncated cone-shaped inner cavity 3, and the ends of the truncated cone-shaped inner cavity have integrally formed limiting protrusions 4. In this embodiment, the outer and inner ring bodies are both integrally molded from rubber and can be assembled together during use. The outer shape of the inner ring body is a truncated cone-shaped outer wall, and the inner wall of the inner ring body has a plurality of integrally formed protrusions 5. During assembly, the inner ring body is located within the outer ring body, and the limiting protrusions respectively abut against the end surfaces of the inner ring body. This structure improves the ease and stability of assembly of the inner ring body and also facilitates replacement or maintenance of the inner or outer ring body.

[0020] Moreover, in actual application, a plurality of protrusions 6 are integrally formed on the inner surface of the limiting convex ring; circular holes 7 are provided on both end surfaces of the inner ring body; during assembly, the protrusions are inserted into the circular holes. The above structure can improve the assembly stability and reliability of the inner ring body.

[0021] In actual use, the sidewalls of the inner and outer rings are each provided with a plurality of buffer holes 8, which are staggered. The inner diameter of the inner ring is smaller than that of the retaining ring. By staggering the buffer holes, the shock absorption performance can be improved while ensuring sealing.

[0022] The utility model has positive effects: the structure of the utility model is reasonably set up, and its shock-absorbing rubber ring is composed of an outer ring body and an inner ring body, and the outer wall of the inner ring body and the inner wall of the outer ring body are both frustum-shaped, which is beneficial to improving the effectiveness and stability of sealing and shock absorption when used in combination, and also facilitates the replacement or maintenance operation of the local structure, making it more convenient to use.

[0023] 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.

[0024] 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.
