Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0014] Participate figure 1 As shown, the hydraulic cylinder includes a cylinder block 1, a piston 2, a piston rod 3, a front cylinder head 4, and a rear cylinder head 5. The cylinder block 1 has a communicating cavity in the axial direction, and the piston 2 slides in the cavity. One end of the piston rod 3 is fixed to the piston 2, and the other end extends out of the cavity. The rear cylinder head 5 is sealed and fixed to one end of the cylinder block 1, and th...

Abstract

The invention discloses a hydraulic device. A hydraulic cylinder includes a cylinder body, a piston, a piston rod, a front cylinder cover and a back cylinder cover; the cylinder body is provided with an axially communicated cavity; the piston slides in the cavity; one end of the piston rod is fixed with the piston, and the other end extends to the external of the cavity; the back cylinder cover is fixedly sealed at one end of the cylinder body; the front cylinder cover coats the piston rod, and is fixed at the other end of the cylinder body; an annular first cylinder body sleeve is projected on one side, facing to the cylinder body, of the front cylinder cover; and the first cylinder body sleeve coats the outer side of a second cylinder body. The hydraulic device is convenient for installation of the hydraulic cylinder, low in manufacturing cost and excellent in sealing performance.

Description

Technical field [0001] This application relates to a hydraulic device. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable work. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable. Therefore, it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference between its two sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. [0003] The traditional hydraulic cylinder has technical problems of inconvenient assembly and poor sealing. Summary of the invention [0004] The ...
