Automatic abnormal-sound-free wear-resistant shock absorber for dust-proof device

Abstract

The invention discloses an automatic abnormal-sound-free wear-resistant shock absorber for a dust-proof device. The automatic abnormal-sound-free wear-resistant shock absorber comprises a shock absorption bottom plate, a shock absorption top plate, a shock absorption column and a piston, wherein guide structures are mounted on the two sides of the top end of the shock absorption bottom plate correspondingly, and a lubricating structure is mounted at one end of a shock absorption cylinder. Pressure resistance of the shock absorber is improved through the guide structures, the shock absorption column and a second telescopic spring are pressed downwards through the shock absorption top plate, the shock absorption column drives the piston to slide in the shock absorption cylinder; and meanwhile, the shock absorption top plate can drive a slide rod to slide in a slide hole, the slide rod can drive a connecting block to extrude the spring and move downwards, and a connecting block can drivepulleys on the two sides to slide on a slide rail; guide performance of the connecting block can be enhanced when the pulleys slide on the slide rail, then the guide performance of the piston in the shock absorption cylinder can be enhanced, the two sets of first telescopic springs work at the same time, pressure resistance of the shock absorber is improved, and then the service life of the shockabsorber is prolonged.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to an automatic dust-proof shock absorber without abnormal noise and wear resistance. Background technique [0002] With the rapid development of the national economy and the continuous improvement of the level of science and technology, the development of my country's machinery manufacturing industry is getting better and better. The shock absorber is used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. The shock absorber is widely used. Used in the automotive field, in order to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the car, when passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock-absorbing The shock absorber is used to suppress the jump of this spring...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an automatic dust-proof device shock absorber with no abnormal noise and wear resistance, so as to solve the problem of poor compression resistance in the above-mentioned background technology, and it is not convenient to guide and limit the shock absorber during shock absorption. In turn, the shock absorber is seriously damaged, shortening the service life of the shock absorber, and affecting the overall use of the shock absorber.
