Problems solved by technology

After using this balanced gas spring for a period of time, the elastic force of the internal spring will become smaller. If you need to adjust the compression of the spring (or adjust the speed of the gas spring) to change the elastic effect of the entire gas spring, It is necessary to take the piston and piston rod out of the cylinder to adjust, and the adjustment efficiency is low

Abstract

The invention belongs to the technical field of gas springs, and particularly relates to a balanced gas spring. The balanced gas spring comprises a cylinder barrel, a front seal, a rear seal, a piston and a piston rod; the front seal and the rear seal are located at two ends of the cylinder barrel correspondingly, and the piston rod is sleeved with the front seal; the piston is located in the cylinder barrel and is in threaded connection with the piston rod, and the end, penetrating through the piston, of the piston rod is in threaded connection with a nut; an outer edge ring groove is concavely formed in the middle of the outer circumferential face of the piston; a sealing ring is arranged in the outer edge ring groove; and an end face ring groove is formed in the end face of the end, facing the front seal, of the piston. According to the invention, under the condition that the gas spring is not disassembled, a working spring can be rapidly adjusted, the adjusting efficiency is high, and the process is convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of gas springs, in particular to a balanced 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. The Chinese patent with the application number CN2019203468505 discloses a balanced gas spring, which includes a barrel, a piston, a front plug, a rear plug, a piston rod, a compression ring, a spring and a sealing ring, and the outer wall of the piston is provided with a ring along the circumferential direction. groove, the sealing ring is placed in the ring groove, the ring groove isolates the front ring platform and the rear ring platform on the piston, and the front end of the piston rod is fixedly connected with the piston so that the piston connects the cylinder The internal isolation is a front cavity and a rear cavity, and the piston is provided with at least one through overflow ...
