Hydraulic oil cylinder with protective structure and using method

Abstract

The hydraulic oil cylinder with the protection structure comprises a cylinder barrel, an upper sealing cover, a lower sealing cover, a piston, a hydraulic rod, an oil outlet pipe head, an adjustable mounting seat structure, an oil filtering treatment barrel structure, an exhaust pressure relief protection pipe structure and a buffer connection protection barrel structure, one end of the cylinder barrel is in threaded connection with the upper sealing cover, and the other end of the cylinder barrel is in threaded connection with the lower sealing cover; a piston is arranged in the cylinder barrel; the middle part in the piston is in threaded connection with a hydraulic rod; and the hydraulic rod penetrates through the middle part in the upper sealing cover. Through the arrangement of the butt joint lining, the connecting sleeve, the fixed disc, the buffer spring, the outer sheath, the movable disc and the movable connecting sleeve, buffer protection can be carried out, and damage is avoided; through the arrangement of the exhaust pipe, the protective cover, the pressure relief screw rod, the pressure relief plug, the rotating handle and the pressure relief hole, air and pressure can be released, so that the pushing stability is ensured, and empty pushing force release is avoided.

Description

technical field [0001] The invention belongs to the technical field of hydraulic cylinders, and in particular relates to a hydraulic cylinder with a protective structure and a use method. Background technique [0002] A 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 operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. [0003] At present, hydraulic cylinders are widely used. [0004] However, the existing hydraulic oil cylinders have the problems of inconvenient use and operation, inability to install and adjust, not having the function of pressure relief and exhaust protection, not having the function of filtering oil, and being inconvenient for buffer connec...
