Abstract
The invention provides a piston rod. A ventilation hole is formed in the bottom of a hollow containing cavity in a piston rod body and inflated with high-pressure gas, so that a spaced gas field is formed between the rod and a base, and it is guaranteed that the friction coefficient between the rod and the base is reduced, and the service life of products is prolonged. The rod body is sleeved with a fixed plate. The fixed plate is provided with a bolt. The bolt penetrates a movable plate. The movable plate and the bolt are in threaded connection. The movable plate is provided with an installing hole and can be connected with other parts. The distance between the movable plate and the fixed plate can be adjusted by rotating the bolt.
Description
Technical field
The present invention relates to a kind of piston rod.
Background technology
Prior art is connected by bar-hole between piston rod and piston seat and coordinates.Piston rod inserts seat mechanical movement in piston seat.Owing to the rigidity friction between piston rod and piston seat causes noise abnormal and rub detracting the service life of product.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of piston rod, its objective is to provide a kind of service life long, and the parts driving other parts to move together can be installed.
A kind of piston rod, it is provided with the hollow host cavity for matching with piston seat in including the piston body of rod body described in piston body of rod body of column, the bottom of described hollow host cavity is provided with passage, gases at high pressure can be filled with in hollow host cavity by this passage, the middle part of described piston body of rod body is provided with connecting portion, the bottom of described connecting portion is the body of rod, and the described body of rod is arranged with fixed plate.
Preferably, described fixed plate being provided with bolt, described bolt passes a portable plate, and described portable plate is threaded connection with described bolt.
Preferably, described portable plate is provided with installing hole.
A kind of piston rod that the present invention provides, it has the beneficial effects that: the bottom of the hollow host cavity on piston rod body is provided with passage, being filled with gases at high pressure in passage, the gas field so forming interval between bar and seat ensures that between bar and pedestal, coefficient of friction reduces the service life extending product.Being arranged with fixed plate on the described body of rod, described fixed plate is provided with bolt, described bolt passes a portable plate, and described portable plate is threaded connection with described bolt, and described portable plate is provided with installing hole, can be connected with miscellaneous part.Rotating bolt can be with the distance of regulation portable plate with fixed plate.
