Problems solved by technology

Generally, there will be a gap between the damping piston and the cylinder. When the piston rod is compressed and retracted, the damping piston will deviate to one side and rub against the inner wall of the cylinder, causing the damping force to change and the damping force to be unstable. , affecting the damping buffer effect

Embodiment Construction

[0009] Such as figure 1 , 2 As shown, a damper includes a cylinder barrel 1 with a liquid storage cylinder section 1.1 and a hydraulic cylinder section 1.2, a plug cover 2 fixed on the mouth of the cylinder barrel 1, a sealing ring plug 3 on the liquid storage cylinder section 1.1, and a plug on the hydraulic cylinder section 1.1. The damping piston 4 of the hydraulic cylinder section 1.2, the piston rod 5 that is fixed to the damping piston 4 and slides through the sealing ring plug 3 and passes through the plug cover 2, and the spring 6 that keeps the sealing ring plug 3 sliding towards the hydraulic cylinder section 1.2 . In the present invention, the inner peripheral wall of the hydraulic cylinder section 1.2 of the cylinder 1 forms several axially extending ribs 1.3.

[0010] The cylinder barrel 1 is divided into two sections by a retaining ring 1.3, the inner section is a hydraulic cylinder 1.2, and the outer section is a fluid storage cylinder 1.1. The sealing ring p...

Abstract

The invention discloses a damper. The damper comprises a cylinder barrel which is provided with a liquid storing cylinder section and a hydraulic cylinder section, a plug lid which is fixed to an opening of the cylinder barrel, a sealing ring plug which is arranged on the liquid storing cylinder section, a damping piston which is disposed on the hydraulic cylinder section, a piston rod which is fixed to the damping piston, penetrates through the sealing ring plug in a sealing sliding mode and penetrates out of the plug lid and a spring which keeps the sealing ring plug in a tendency to slidingtowards the hydraulic cylinder section. The damper is characterized in that a plurality of axially-extending protruding ribs which are formed on the inner circumference wall of the hydraulic cylindersection of the cylinder barrel. As the multiple protruding ribs are formed on the inner circumference wall of the hydraulic cylinder section of the cylinder barrel, sliding of the damping piston is limited through the protruding ribs, side friction between the damping piston and the inner wall of the cylinder barrel is prevented, change of the damping degree is prevented, and thus the constant damping degree of the damper is ensured.

Description

technical field [0001] The invention relates to the technical field of hydraulic dampers. Background technique [0002] In the furniture industry, the self-closing device often uses a damper with a long stroke to buffer the self-closing. The damper is mainly composed of a cylinder with a liquid storage cylinder section and a hydraulic cylinder section, a plug cap fixed at the mouth of the cylinder barrel, a sealing ring plug at the liquid storage cylinder section, a damping piston at the hydraulic cylinder section, and a fixed damping piston. And the sealing slides through the piston rod of the sealing ring plug and passes through the plug cover, and the spring that keeps the sealing ring plug sliding towards the hydraulic cylinder section. A retaining ring inside the cylinder is divided into two sections, the inner section is the hydraulic cylinder, and the outer section is the fluid storage cylinder. Generally, there will be a gap between the damping piston and the cylin...
