Description

Seat gas spring

Technical Field

The utility model relates to the technical field of springs, in particular to a seat gas spring.

Background

The gas spring (gas spring) is an industrial fitting which can play the roles of supporting, buffering, braking, height adjustment, angle adjustment and the like. It is composed of the following parts: a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, a filler (inert gas or oil-gas mixture), an in-cylinder control element, an out-cylinder control element (referred to as a controllable gas spring), a joint and the like. The principle is that inert gas or oil-gas mixture is filled in a closed pressure cylinder to make the pressure in the cavity be several times or tens times higher than the atmospheric pressure, and the piston rod is moved by the pressure difference generated by the fact that the cross section area of the piston rod is smaller than that of the piston. Due to the fundamental differences in principle, gas springs have significant advantages over conventional springs: the speed is relatively slow, the dynamic force is not changed greatly (generally within 1:1.2), the control is easy, and the swivel chair gas spring is widely used for office chairs, working chairs, bar chairs and the like.

Such as Chinese patent: "CN204300212U", the technical scheme disclosed in this patent is as follows: the seat gas spring is characterized by comprising a tube body, a sleeve head and a piston rod, wherein the piston rod is inserted into the sleeve head, a clamping recess is arranged on the tube body, and the clamping recess is clamped with a clamp on the sleeve head; the sleeve head is provided with a reinforcing rib, and the strength of the sleeve head is increased through the reinforcing rib; the tail of the tube body is a trapezoid shrinkage tube and is provided with a plurality of compression holes.

The gas spring on the seat mainly provides certain thrust for the lifting adjustment of the seat, and after the gas spring is installed, the stroke cannot be changed, but in practice, the compression amount of the gas spring may need to be adjusted to obtain different thrust and strokes, and the gas spring with the stroke incapable of being adjusted causes great inconvenience to a user.
