Problems solved by technology

Due to the fundamental difference in principle, gas springs have significant advantages over ordinary springs: relatively slow speed, little change in dynamic force (generally within 1:1.2), and easy control; The gas spring is used to realize the elastic support function through the gas spring, but because the traditional gas spring can only realize the function of elastic linear expansion and contraction, there are many auxiliary parts when installing the gas spring, which increases the complexity of installation and the cost of manufacturing. It also limits the scope of use of gas springs

Abstract

The invention discloses a torsion gas spring which comprises a cylinder body, wherein a base is fixed at one inner end of the cylinder body; a threaded rod is fixed at the center of the base; a threaded sleeve is arranged on the threaded rod and connected with a piston body; the piston body is arranged in the cylinder body in a sliding manner; the other end of the piston body is movably connected with a rotating body; the rotating body is movably arranged at the other end of the cylinder body; connecting arms are arranged at the outer ends of both the rotating body and the base; and a gap between the piston body and the base is fully filled with compressed air. According to the above technical scheme, a linear telescopic gas spring can be transformed into the torsion gas spring, and the functions and the advantages of a gas spring can be kept. Therefore, the gas spring application range is greatly expanded, gas spring mounting accessories are greatly simplified, and the gas spring can be more flexible and convenient to use.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a torsion gas spring. Background technique [0002] Gas spring is an industrial accessory that can perform functions such as support, buffer, brake, height adjustment and angle adjustment. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler ( inert gas or oil-air mixture), in-cylinder control elements and out-of-cylinder control elements (referring to controllable gas springs) and joints, etc. The principle is to fill the airtight pressure cylinder with an inert gas or an oil-gas mixture, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure. cross-sectional area The movement of the piston rod is achieved by a pressure difference smaller than the cross-sectional area of ​​the piston. Due to the fundamental difference in principle, gas springs have significant advantages o...
