Abstract

A single-acting cylinder relates to a driving part utilizing air as the power source and comprises a cylinder sleeve and a piston arranged in the cylinder sleeve. An end cover is arranged at one end of the cylinder sleeve, and the other end of the cylinder sleeve is provided with air inlet holes. A driving rod is arranged between the end cover and the piston, one end of the driving rod is connected with the piston, and the other end of the driving rod penetrates through a central hole of the end cover. The diameter of the driving rod is smaller than that of the piston, and a returning spring is arranged between the end cover and the piston and wound on the outer circumferential face of the driving rod. The single-acting cylinder is simple in structure, low in cost and easy to maintain, drives the piston to move by compressing an air source and then drives the driving rod to move vertically. When the air source is closed, a preset spring with pre-tightening force automatically resets the piston, thereby being very convenient to use.

Description

A kind of single-acting cylinder

Technical field

The utility model relates to a kind of driver part that adopts gas as power source, a kind of single-acting cylinder specifically.

Technical background

At present; The cylinder that sell in market mainly is made up of cylinder liner and the piston that is arranged in the cylinder liner, and through the compressed gas-driven piston assembly, the cylinder of the type is equipped with two suction ports; Change the movement direction of piston through the position that changes air inlet; Therefore this driver part pipeline is comparatively complicated, and it is bigger to take up room, comparatively narrow and small then inapplicable this series products in place in some spaces.

The model utility content

The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of single-acting cylinder is provided, and it is simple in structure, and using effect is better.

The utility model is the deficiency that solves the problems of the technologies described above, and the technological scheme that is adopted is: a kind of single-acting cylinder comprises cylinder liner and the piston that is arranged in the cylinder liner; End in cylinder liner is provided with end cap, and the other end is provided with inlet hole, on end cap, is provided with exhaust port; Be provided with driveshaft between end cap and the piston; One end of driveshaft is connected with piston, and the other end passes the center hole of end cap, and the diameter of driveshaft is less than the diameter of piston; Between end cap and piston, be provided with Returnning spring, Returnning spring is looped around on the outer peripheral surface of driveshaft.

Be provided with seal ring between the outer peripheral surface of described piston and the cylinder liner internal wall, seal ring is fixed on the piston.

Also be provided with spring seat on the described end cap, Returnning spring one end is positioned at spring seat, and the other end withstands on the piston end face.

Described end cap is that internal and external threads is connected with Placement between the cylinder liner.

Also be provided with two interior threaded holes on the described end cap.

Be provided with filtrating equipment in the described exhaust port.

Described driveshaft and piston are structure as a whole.

The beneficial effect of the utility model is:

The utility model, simple in structure, the low and easy-maintaining of price through the motion of compressed gas source driven plunger, drives driveshaft and moves up and down, and when source of the gas was closed, the spring that is provided with pretightening force in advance is automatically with piston reset, and was very easy to use.
