Description
Technical Field
The utility model relates to a sole processing technology field especially relates to a right side that sealing performance is excellent plays to rise hydro-cylinder.
Background
The lifting oil cylinder is a hydraulic actuating element which converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or swinging motion). It has simple structure and reliable operation. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The output force of the lifting oil cylinder is in direct proportion to the effective area of the piston and the pressure difference between the two sides of the piston; the lifting oil cylinder basically comprises a cylinder barrel, a cylinder cover, a piston rod, a sealing device, a buffering device and an exhaust device.
The sealing performance of a lifting oil cylinder commonly used in the prior art is poor, so that the service life of the lifting oil cylinder is short.
SUMMERY OF THE UTILITY MODEL
To prior art's defect and not enough, the utility model aims to provide a right side that sealing performance is excellent plays to rise hydro-cylinder.
The utility model provides a following technical scheme:
the utility model provides a right side that sealing performance is excellent plays to rise hydro-cylinder, includes the cylinder body, the inside piston assembly that is provided with of cylinder body, piston assembly's output is provided with the piston rod, piston assembly's the other end is provided with explosion-proof stopper, the left side bottom of cylinder body is provided with the dust ring, the right side of dust ring is provided with the uide bushing, still be provided with the steel backing bearing on the piston rod, piston assembly's the output is provided with the steel wire retaining ring with the inside contact position of piston rod, piston assembly's periphery still is provided with the support ring, piston assembly's outside still is provided with separation blade and first U type sealing washer.
As a further proposal, the contact part of the guide sleeve and the piston rod is provided with a second U-shaped sealing ring.
As a further proposal, the contact position between the steel back bearing and the inside of the cylinder body is provided with an O-shaped sealing ring.
The utility model provides a pair of right side that sealing performance is excellent plays to rise hydro-cylinder, beneficial effect lies in:
the utility model discloses simple structure facilitates the use, through the reasonable setting of dust ring and various sealing washers, can effectual promotion piston rod sealing performance at the in-process of motion, and then the effectual life who plays to rise the hydro-cylinder that has prolonged.
