Embodiment Construction

[0014] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] Such as figure 1 As shown, an auxiliary return type gas spring of the present invention has a cylinder 1 and a piston assembly, the piston assembly includes a piston 2 and a piston rod 3, the piston 2 is fixed on one end of the piston rod 3, and one end of the piston rod 3 extends Into the cylinder 1 and the piston 2 is located inside the cylinder 1, the side wall of the piston 2 is in clearance fit with the cylinder 1, and the end of the cylinder 1 extending into the piston rod 3 is provided with a vibration-damping sealing structure, so The vibration-damping sealing structure includes a buffer ring 4 and three seal rings 5, the inner ring of the buff...

Abstract

The invention relates to an auxiliary resetting gas spring which is provided with a cylinder barrel, a piston and a piston rod, wherein the cylinder barrel is internally provided with a damping seal structure so that not only can the piston rod be sealed, but also a damping effect on the piston can be achieved; a triangular apex angle part of a seal ring is in contact with the piston rod, so that the seal effect is further improved; and the cylinder barrel is internally provided with a compression spring, and the compression spring is capable of not only achieving a buffering effect on the piston, but also providing pull force and push force, assisting the back-and-forth movement of the piston and preventing excessively high or low resetting speed of the gas spring.

Description

technical field [0001] The invention relates to an auxiliary return type gas spring. Background technique [0002] The gas spring is mainly composed of a cylinder, a piston in the cylinder, a piston rod and a valve core, etc., and gas and oil are stored in the cylinder. Since the piston occupies the volume of the cylinder, the piston rod is pressed into the cylinder during work, and the piston moves axially in the cylinder to squeeze the oil, and the oil compresses the gas to make the piston reach the working position; when loaded on the piston After the external force on the rod disappears, the gas recovers and expands, and the expanded gas pushes the oil to reset the piston, and the piston rod is moved out, so that the gas spring realizes compression motion and recovery damping motion. For the locking gas spring, the oil passage is quickly opened or closed through the axial movement of the spool set in the piston rod. However, during the reset process of the gas spring, ...
