Problems solved by technology

[0002]At present, when processing various parts of the gas spring, it is necessary to use a high-power riveting press to rivet the valve body. Poor pressure resistance, so it is easy to cause deformation of the end face of the valve body, which affects the subsequent processing procedures, thereby reducing work efficiency

Embodiment Construction

[0010] As shown in the figure, a gas spring device includes a steel pipe (1). One end of the steel pipe (1) is provided with a valve body assembly (2) and a piston assembly (3) from the inside to the outside, and a tail plug is provided at the port at the other end. There is also a partition piston inside the steel pipe (1), which is characterized in that: the valve body assembly (2) has a valve body (21), a valve needle (22) inserted into the valve body (21) and a gasket, Two V-shaped grooves (211) are formed on the end surface of the body (21), and the valve needle (22) is arranged between the two V-shaped grooves (211).

[0011] Preferably, the V-shaped groove (211) is stamped and formed. Further, the first fixing portion extends obliquely upward from the slope of the first body.

Abstract

The invention discloses a gas spring device. The gas spring device is characterized by being capable of facilitating machining of each part and comprising a steel tube, one end of the steel tube is provided with a valve assembly and a piston assembly from inside to outside, the end opening of the other end of the steel tube is provided with an end plug, a separation piston is arranged in the steel tube, the valve assembly comprises a valve body, a valve needle and a gasket, one end of the valve needle extends into the valve body, the end surface opposite to the separation piston in direction, of the valve body is provided with two V-shaped grooves, the head of the other end of the valve needle is arranged between the two V-shaped grooves. The gas spring device is simple in structure and is provided with the V-shaped grooves in the end surface of the valve body for improving the compressive strength of the end surface of the valve body and increasing the working efficiency.

Description

technical field [0001] The invention relates to the technical field of gas springs, in particular to a gas spring which is easy to process and easy to process. Background technique [0002] At present, when processing various parts of the gas spring, it is necessary to use a high-power riveting press to rivet the valve body. Due to the poor pressure resistance of the valve body end face of the valve body assembly, it is easy to cause deformation of the end face of the valve body. Thereby affecting subsequent processing procedures, thereby reducing work efficiency. Contents of the invention [0003] The object of the present invention is to provide a gas spring device with simple structure. [0004] A gas spring device, comprising a steel pipe (1), one end of the steel pipe (1) is provided with a valve body assembly (2) and a piston assembly (3) from the inside to the outside, and a tail plug is provided at the port of the other end of the steel pipe (1). 1) There is also...
