Description

Technical Field

[0001] The utility model relates to the technical field of gas springs, in particular to a low temperature resistant structure of a gas spring. Background Art

[0002] A gas spring is an elastic element that uses gas and liquid as working media. It is mainly composed of a cylinder, a piston in the cylinder, a piston rod and a guide sleeve. Gas and part of the oil are stored in the cylinder. Since the piston occupies the volume in the cylinder, the piston rod is pressed into the cylinder during operation. The piston moves axially in the cylinder to squeeze the oil in the cavity, and the oil compresses the gas to make the piston reach the working position. When the external force loaded on the piston rod disappears, the gas recovers and expands. The expanded gas pushes the oil to reset the piston and move the piston rod out, so that the gas spring can achieve compression movement and recovery damping movement.

[0003] The low-temperature resistant structure of the existing gas spring has the following disadvantages when used. Most of the existing gas springs cannot be used normally in a low temperature environment. The low temperature in the air can easily cause damage to the inside of the gas spring, thereby reducing the service life of the gas spring, thereby increasing the use cost of the staff, and at the same time having a certain impact on the work of the staff, thereby reducing the work efficiency of the staff, and is therefore not conducive to the use of the staff.
