Vertical shock absorber structure with lifting function

Abstract

The invention discloses a vertical shock absorber structure with a lifting function. The vertical shock absorber structure with the lifting function comprises a lifting ring seat assembly, wherein a connection rod is installed on the lower part of the lifting ring seat assembly, a downward telescopic dustproof cover is installed on the outer circumferential surface of the connection rod, guide seat assemblies of two groups of adjustment valves which are symmetrically arranged are installed on the connection rod located at the lower end of the telescopic dustproof cover, a piston assembly is installed at the bottom of the connection rod, steps are arranged on the connection rod located on the upper part of the piston assembly, and a stopper is fixed at each step through a steel cable baffle ring; and each guide seat assembly structurally comprises a guide seat fixed on the connection rod through a sealing device, an adjustment hole is formed in each guide seat, an adjustment seat is installed in each adjustment hole through an O-shaped sealing ring, an adjustment nut is installed at the top of each adjustment seat, a spring seat is arranged at the bottom of each adjustment seat, an adjustment spring is installed in each spring seat, a valve element is further installed at the bottom of each adjustment hole, and an oil return tube is further comprised, and connected with an oil return hole of the corresponding guide seat. The vertical shock absorber structure with the lifting function plays a role of protecting a shock absorber.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a vertical shock absorber structure with a lifting function. Background technique [0002] At present, shock absorbers have been widely used. According to the needs of customers, in many applications, shock absorbers with lifting function requirements are required. [0003] The shock absorber in the prior art does not have a hoisting function. When hoisting, the shock absorber is stretched, and the piston assembly will be damaged due to the force generated by the hoisting weight. Contents of the invention [0004] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a vertical shock absorber structure with a reasonable structure and a lifting function, so as to improve the reliability of use and protect the piston assembly. [0005] The technical scheme adopted in the present invention is as follows: [0006] A vert...
