Abstract

The invention relates to a damper, in particular to a shrinkage power-assisted damper. The shrinkage power-assisted damper comprises a cylinder barrel and a piston rod component arranged inside the cylinder barrel, wherein a sealing component is fixed at a specified position of the middle of the cylinder barrel and is used for sealing and separating a first cavity and a second cavity; the piston rod component comprises a piston rod, a gasket, a piston ring and a piston, and the gasket, the piston ring and the piston are fixed at the tail end; the piston end of the piston rod is arranged in thefirst cavity; the middle of the piston rod is a stepped step surface; the stepped step surface is arranged in the second cavity; the sealing component is in large diameter sealing with the inner wallof the cylinder barrel and the piston rod; a hole-slot structure is arranged at a connecting part of the gasket and the piston rod; the tail end of the second cavity is sealed by an air seal; and a guide block is further arranged on the exterior of the air seal to perform revolving-riveting and sealing. The shrinkage power-assisted damper effectively solves the dilemma that the existing damper itself cannot stabilize the force assisting.

Description

technical field [0001] The invention relates to a damper, in particular to a contraction booster damper. Background technique [0002] With the development of industrial technology, the functional requirements of gas springs are getting higher and higher. Many existing downward turning mechanisms are provided with dampers, so as to achieve the effect of slow down. But because all existing dampers do not have the function of assisting in the direction of contraction. Therefore, in order to reduce the hand feeling force when the flip-down mechanism is closed, the existing methods are usually: 1. Increase stage clips inside the damper, thereby producing a resistance effect when the damper is stretched. 2. An extension spring is added to the downward turning mechanism to be used in conjunction with the damper. So as to achieve the effect of damping and assisting. The problem that above-mentioned practice exists is as follows: (1) the assisting effect that stage clip produces...
