Abstract
The utility model discloses a master piston, which comprises a cylindrical piston body, wherein annular sealing rings are arranged at one end of the piston body, and a step hole is arranged at the other end of the piston body; and a sealing ring groove is arranged between the adjacent annular sealing rings. The master piston has the advantages of reasonable structural design, low working noise and prolonged service life, and the master piston is matched with a cylinder body more flexibly.
Description
Technical field
The utility model relates generally to a kind of main piston.
Background technique
Hydraulic jack is made up of cylinder barrel, piston rod (cylinder rod), piston, several parts of end cap.The quality of its quality of processing directly influences the life-span and the reliability of entire product.Piston rod processing request height, its surface roughness require to be Ra0.4～0.8um, and be strict to coaxality, wear resistance.The essential characteristic of cylinder rod is the slender axles processing, and its difficulty of processing is big, perplexs the processing personnel always.
The model utility content
The purpose of this utility model provides a kind of main piston, and reasonable in design cooperates more flexibly with cylinder body, and operational noise is little, and prolong working life.
The technical solution adopted in the utility model is as follows:
A kind of main piston includes the piston body of tubular, and an end of piston body is provided with O-ring seal, and the other end offers step hole, has closure gasket groove between the adjacent O-ring seal.
The end of described piston body is provided with strut.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Reasonable in design of the present utility model cooperates more flexibly with cylinder body, operational noise is little, and prolong working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
