Rubber shock absorber with spring wrapped inside

Abstract

The utility model discloses a rubber shock absorber with a spring inside and belongs to the technical field of rubber shock absorbers. The first rubber body wraps the outer wall face and the bottom face of the upper copper sleeve in a surrounding mode, the second rubber body wraps the top face and the outer wall face of the lower copper sleeve in a surrounding mode, and the spring is arranged in a cavity formed by the first rubber body and the second rubber body, wrapped by the first rubber body and the second rubber body and located between the upper copper sleeve and the lower copper sleeve. The spring is additionally arranged and is designed to be of an inner wrapping structure, the problem that the rubber body cracks when bearing too large impact force and cannot be better buffered is solved, the spring is used for assisting in force unloading, the long-time strong and hard impact force is relieved, and the damping device is more stable in use and better in damping effect during use; the rubber body is designed to be of an internally-wrapped spring structure, the problems that the spring pops up and moves can be solved, meanwhile, by adding the spring, part of force needing to be borne by the rubber body is dispersed, the risk that impact force is concentrated in the rubber body and cannot be well dispersed out, and consequently cracks occur is avoided, and the service life is prolonged.

Description

Technical Field

[0001] This utility model belongs to the technical field of rubber shock absorbers, specifically relating to an internally wrapped spring rubber shock absorber. Background Technology

[0002] The damping effect, stability, and service life of rubber shock absorbers are very important. The existing structure of rubber shock absorbers is an all-rubber structure, which ultimately leads to the risk of cracks in the rubber body when the shock absorber is used under complex working conditions, resulting in poor stability. Utility Model Content

[0003] In order to solve the problems of cracking and lack of good cushioning in rubber shock absorbers under complex working conditions, this utility model provides an internally wrapped spring rubber shock absorber.

[0004] The technical solution adopted by this utility model is:

[0005] An internally wrapped spring rubber shock absorber includes an upper copper sleeve, a lower copper sleeve, a first rubber body, a second rubber body, and a spring; the first rubber body surrounds and wraps the outer wall and bottom surface of the upper copper sleeve, the second rubber body surrounds and wraps the top surface and outer wall surface of the lower copper sleeve, the first rubber body and the second rubber body are connected, and the spring is disposed in the cavity formed by the first rubber body and the second rubber body, and is wrapped by the first rubber body and the second rubber body, and is located between the upper copper sleeve and the lower copper sleeve.

[0006] Compared with the prior art, the present invention has the following advantages:

[0007] This utility model's rubber shock absorber incorporates a spring with an internally enclosed structure. This enclosed spring structure prevents the rubber from cracking due to insufficient cushioning under excessive impact. The spring assists in dissipating and mitigating strong impacts, making it more stable and improving shock absorption during use. Furthermore, the internal spring design prevents the spring from popping out or shifting. The addition of the spring also disperses some of the force borne by the rubber, preventing impact from concentrating inside the rubber and causing cracks. This also extends the lifespan. Experimental use has shown a significant improvement in shock absorption, and no minor cracks have appeared even under complex operating conditions. Attached Figure Description
