Abstract

The utility model relates to the technical field of automobile parts, in particular to a firm piston type spring cylinder. The spring cylinder comprises a front cylinder, a rear cylinder, a diaphragm, an energy storage spring, an energy storage plate, a return spring, a return plate and a push rod, wherein the front cylinder is connected with the rear cylinder; the diaphragm is located between the front cylinder and the rear cylinder; the energy storage spring is mounted in the rear cylinder; two ends of the energy storage spring are sleeved with the energy storage plate; the return spring is mounted in the front cylinder and arranged on the push rod in a sleeving manner; the return plate is located at the tail part of the return spring and connected with the push rod; and fixing rings are arranged between the front cylinder and the rear cylinder. The front cylinder and the rear cylinder are connected at two ends of each fixing ring; the spring cylinder is simple in structure, convenient to assemble, firmer and more stable in connection, and the overall performance of the spring cylinder is improved greatly; and further, the diaphragm is independently embedded in clamping grooves in the center of the inner walls of the fixing rings and not contacted with the front cylinder and the rear cylinder, so that mutual influence and damage are avoided, the performance of the diaphragm is improved, and the service life is prolonged.

Description

Firm type piston type spring cylinder
Technical field
The utility model relates to auto parts machinery technical field, especially a kind of firm type piston type spring cylinder.
Background technique
Existing piston type spring cylinder housing is to adopt clip by integral clamping after the superimposed crimping of outer rim flange of front cylinder, diaphragm and rear cylinder, this structure makes housing metal cross limit of elasticity to deform, it is not firm not only to connect, easily generation cracking leakage, and the assembling magnitude of interference of diaphragm is difficult to constant, has shortened the working life of diaphragm and spring cylinder, greatly reduce the reliability of spring cylinder, assemble in addition difficulty also large, inefficiency, affects the overall performance of spring cylinder.
Model utility content
Not firm in order to overcome existing spring cylinder structure, leakage easy to crack, the deficiency that working life is short, the utility model provides a kind of firm type piston type spring cylinder.
The utility model solves the technological scheme that its technical problem adopts: a kind of firm type piston type spring cylinder, comprise front cylinder, rear cylinder, diaphragm, energy storage spring, energy storage plate, return spring, return plate and push rod, front cylinder is connected with rear cylinder, diaphragm is between front cylinder and rear cylinder, energy storage spring is arranged in rear cylinder, energy storage plate is enclosed within the two ends of energy storage spring, return spring is arranged in front cylinder, be enclosed within on push rod, return plate is positioned at the afterbody of return spring, be connected with push rod, between front cylinder and rear cylinder, be provided with retaining ring, the two ends of retaining ring are provided with screw channel, front cylinder and rear cylinder are threaded integral by retaining ring, diaphragm is independently arranged on retaining ring.
According to another embodiment of the present utility model, further comprise on two inwalls up and down of screw channel and be all provided with screw thread, form two bung flange structures.
According to another embodiment of the present utility model, further comprise and in screw channel, be provided with preloading spring.
According to another embodiment of the present utility model, further comprise that front cylinder and rear cylinder are inserted in screw channel, are connected to the two ends of retaining ring.
According to another embodiment of the present utility model, further comprise that diaphragm is embedded in the draw-in groove of retaining ring inwall central authorities.
The beneficial effects of the utility model are, design a retaining ring with two bung flange structure screw channels, front cylinder and rear cylinder are connected to the two ends of retaining ring, form integrative-structure, not only simple in structure, easy to assembly, and under the interlock of two-sided screw thread, connect firm stable more, and under the effect of preloading spring, effectively prevent from becoming flexible, greatly improved the overall performance of spring cylinder, stop cracking and leak.Diaphragm is independently embedded in the draw-in groove of retaining ring inwall central authorities, does not contact with rear cylinder with front cylinder, and the damage of avoiding influencing each other, has improved the performance of diaphragm, has extended working life.
