Abstract
The utility model discloses a piston rod which comprises a hollow column. A mounting cavity is formed in the column; internal threads are formed at the outer end of the mounting cavity; a spherical groove is formed at one end of the column; internal threaded holes are formed on the inner side of the groove; and an annular groove is formed at the other end of the column. The piston rod has the advantages of reasonable structural design, low noise and prolonged service life, and is more flexibly matched with a cylinder.
Description
Technical field
The utility model relates generally to a kind of piston rod.
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 piston rod, 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 piston rod includes the cylinder of hollow, has the installation cavity in the cylinder, and the outer end that cavity is installed is provided with internal thread, and an end of cylinder is provided with the groove of sphere, and the inboard of groove is provided with interior threaded hole, and the other end is provided with annular groove.
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.
