Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber detection, in particular to an air tightness detection structure of a shock absorber. Background Art

[0002] Shock absorbers are an important component in a car's suspension system, also known as shock absorbers. Their main function is to reduce vibrations and bumps caused by uneven road surfaces when the vehicle is driving, and to improve ride comfort and driving stability. A typical shock absorber consists of a cylinder and a piston, which are filled with a special oil. When the vehicle passes over a bumpy road, the piston moves up and down, and the vibration of the vehicle body is reduced through the damping effect of the oil. Common types of shock absorbers include hydraulic shock absorbers, pneumatic shock absorbers, and electronically controlled shock absorbers. Different types of shock absorbers have different working principles and adjustment methods, and are suitable for different vehicles and driving environments.

[0003] The Chinese utility model patent with application number 202320955684.5 discloses an air tightness detection structure for a shock absorber. Although the utility model drives a dual-axis motor to make the left and right screws start to rotate, since the thread directions of the left and right screws are opposite, and the upper surfaces of the two movable sleeves are respectively fixed with positioning blocks slidably connected to the positioning grooves, the two movable sleeves are positioned so that the two movable sleeves can only move horizontally relative to each other or move away from each other, and the shock absorber to be tested is clamped, thereby achieving the purpose of clamping the shock absorber to be tested. However, the two clamping plates of the utility model are respectively fixed on the opposite sides of the two movable plates, which makes it inconvenient to replace the clamping plates.
