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
the present invention relates to the technical field of air spring, especially a kind of easy to process air spring being convenient to process.
Background technique
at present, all parts of air spring carries out adding man-hour, needs to carry out riveting with powerful riveter to valve body, because the crushing resistance of the valve body end face of valve component is poor, so be just easy to the face deformation causing valve body, thus affect follow-up manufacturing procedure, thus reduce working efficiency.
Summary of the invention
the object of the present invention is to provide a kind of structure simple, and there is gas spring device.
a kind of gas spring device, comprise steel pipe (1), one end of steel pipe (1) is provided with valve component (2) and piston assembly (3) from inside to outside, the port of its other end is provided with tail and blocks up, also piston separator is provided with in steel pipe (1), it is characterized in that: described valve component (2) has valve body (21), inserts the inner needle (22) of valve body (21) and packing ring, the end face of valve body (21) has two V-type grooves (211), and needle (22) is arranged between two V-type grooves (211).
further, described V-type groove (211) impact briquetting.Further, described first fixing part extends obliquely from the inclined-plane of the first main body.
advantage of the present invention:
structure of the present invention is simple, the end face of valve body is offered V-type groove, can improve the compressive strength of valve body end face, and improve working efficiency.
Accompanying drawing explanation
below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
fig. 1 is gas spring device structural representation.
Embodiment
as figure, a kind of gas spring device, comprise steel pipe (1), one end of steel pipe (1) is provided with valve component (2) and piston assembly (3) from inside to outside, the port of its other end is provided with tail and blocks up, also piston separator is provided with in steel pipe (1), it is characterized in that: described valve component (2) has valve body (21), inserts the inner needle (22) of valve body (21) and packing ring, the end face of valve body (21) has two V-type grooves (211), and needle (22) is arranged between two V-type grooves (211).
as preferably described V-type groove (211) impact briquetting.Further, described first fixing part extends obliquely from the inclined-plane of the first main body.
Claims (2)
1. a gas spring device, comprise steel pipe (1), one end of steel pipe (1) is provided with valve component (2) and piston assembly (3) from inside to outside, the port of its other end is provided with tail and blocks up, also piston separator is provided with in steel pipe (1), it is characterized in that: described valve component (2) has valve body (21), inserts the inner needle (22) of valve body (21) and packing ring, the end face of valve body (21) has two V-type grooves (211), and needle (22) is arranged between two V-type grooves (211).
