Embodiment Construction

[0010] Such as figure 1 A kind of spring cylinder shown, comprises cylinder body 1, and described cylinder body 1 two ends are respectively provided with cylinder body end cover 2 and spring end cover 3, and described cylinder body 1 inner left end is provided with spring seat 4, and described spring The right end of the seat 4 is affixed to the piston rod 5, and the outer layer of the spring seat 4 is provided with a return spring 6; there are two return springs 6, and the two return springs 6 are arranged in the opposite direction of rotation; the cylinder end The cover 2 and the spring end cover 3 are sealed and welded to the cylinder body 1 respectively.

[0011] The structure of the present invention is simple, and the two return springs 6 are arranged in the opposite direction of rotation, and are arranged in the spring seat 4; The limited circumferential displacement effectively prevents the rotation of the piston rod 5 and the deviation of the return spring during the...

Abstract

The invention discloses a spring cylinder which comprises a cylinder body. Two ends of the cylinder body are respectively provided with a cylinder body end cover and a spring end cover; a spring seat is arranged at a left end inside the cylinder body; a right end of the spring seat is fixedly connected with a piston rod; an external layer of the spring seat is provided with reset springs; the number of the reset springs which are arranged in a reversing rotating direction mode is two; and the cylinder end cover and the spring end cover are respectively welded with the cylinder body in a sealing mode. The spring cylinder has the advantages of being simple in structure, avoiding rotating direction disability of spring materials in a compression process due to the fact that the two reset springs which are arranged in the reversing turning direction mode are arranged inside the spring seat, effectively preventing rotation of a piston rod and deflection of the reset springs in the compression process of the reset springs due to the fact that the spring seat limits the circumferential displacement, being reliable of the mechanism and rapid and stable in automatic resetting and enabling the bearing capability and service life to be greatly improved due to the utilization of the double springs.

Description

technical field [0001] The invention belongs to the field of automation equipment, in particular to a spring cylinder. Background technique [0002] There is only one spring in the traditional spring cylinder, and the pressure it bears is relatively large, resulting in a short service life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a spring cylinder with long service life. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] A spring cylinder, comprising a cylinder body, cylinder end caps and spring end caps are respectively provided at both ends of the cylinder body, a spring seat is provided at the left end inside the cylinder body, and a piston rod is fixedly connected to the right end of the spring seat, the The outer layer of the spring seat is provided with a return spring. [0006] Preferably, there are two return springs, and the two return s...
