Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic cylinders, and in particular relates to a double-pressure hydraulic rod. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is smooth, so it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both 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. The buffer device and the exhaust device depend on the specific application, and other devices are indispensable.

[0003] The authorization publication number "CN218062903U" records "a bidirectional hydraulic push rod, including a main body component and two sets of dustproof components, wherein the main body component includes a cylinder, two end covers, two piston rods and two pistons, wherein two second through holes are symmetrically opened on the outer wall of the cylinder, and a first through hole is opened on the outer wall of the cylinder; the two end covers are detachably connected to the two ends of the cylinder; the two pistons are symmetrically and slidably arranged inside the cylinder; one end of the piston rod is fixed to the piston, and the other end of the piston rod passes through the corresponding end cover, and the piston rod and the end cover are slidably connected; the dustproof component includes a first groove, a fixed cover and a dustproof ring, wherein the first groove is opened on the end cover; the dustproof ring is sleeved on the outside of the piston rod, and the dustproof ring is fitted with the end cover. As a result, the operation is simple when replacing the dustproof ring, which avoids the workers from disassembling the hydraulic push rod as a whole, thereby improving the workers' work efficiency."
