Abstract

The utility model relates to an air cylinder capable of preventing the rotation of a piston mandril. The air cylinder comprises an air cylinder body, a piston rod and a piston, wherein the rear end ofthe piston rod is fixedly connected with the piston; the piston and the rear end of the piston rod are hermetically placed in a cylinder body of the air cylinder body; both ends of the cylinder bodyare respectively provided with oil-gas inlets and outlets; the two oil-gas inlets and outlets are arranged at both sides of the piston; the front end of the piston rod extends out from a piston rod hole at the front end of the cylinder body; the front end of the piston rod is connected with a square mandril which is placed in a square bushing; and the square bushing is fixed on the air cylinder body. The utility model can prevent the rotation of the piston mandril when the air cylinder works.

Description

A kind of cylinder that prevents the piston mandril rotation
Technical field
The utility model relates to a kind of ejecting rod of cylinder, specifically is a kind of cylinder that prevents the piston mandril rotation.
Background technique
Present cylinder is mainly by cylinder body, piston rod and piston, one end of the piston rod piston that is connected, the one end sealing of piston and piston rod is placed in the cylinder body of cylinder body, the two ends of cylinder body are equipped with Import and Export of Oil and Gas, two above-mentioned Import and Export of Oil and Gas are positioned at the both sides of piston, for easy to process and maintenance good sealing property, present this cylinder piston rod is generally cylindrical, and piston mandril is directly to be connected with piston rod, and piston mandril self is easy to produce rotation when operation like this.
The model utility content
The purpose of this utility model is to provide a kind of cylinder that prevents the piston mandril rotation, adopts square piston mandril to be connected with piston rod, makes cylinder piston mandril when work can not produce rotation.
The utility model is achieved in that
A kind of cylinder that prevents the piston mandril rotation, comprise cylinder body, piston rod and piston, the rear end of the piston rod piston that is connected, the rear portion of piston rod and piston are placed in the cylinder body of cylinder body together, the two ends of cylinder body are equipped with Import and Export of Oil and Gas, two above-mentioned Import and Export of Oil and Gas are positioned at the both sides of piston, the piston rod front end stretches out from the piston rod hole of cylinder body front end, it is characterized in that: the front end of described piston rod is connected with square push rod, in the square push rod side of the being placed in lining, square lining is fixedly on the cylinder body.
The utility model is at the fixing square lining of the front end of cylinder body, in the square push rod side of the being placed in lining, square push rod is connected the front end of piston rod, and piston mandril produces rotation owing to cooperatively interacting of square lining and square push rod can effectively prevent piston mandril when work like this.
Description of drawings
Fig. 1, structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of cylinder that prevents the piston mandril rotation, comprise cylinder body 1, piston rod 2 and piston 3, the rear end of piston rod 2 piston 3 that is connected, the rear portion of piston rod 2 and piston 3 are placed in the cylinder body of cylinder body 1 together, and piston rod 2 front ends stretch out from the piston rod hole of cylinder body front end, and the front end of described piston rod 2 is connected with square push rod 4, in square push rod 4 side's of being placed in linings 5, square lining 5 is fixed on the cylinder body 1.
The utility model is connected the front end of piston rod at described square piston push rod, there is side's lining to be fixed on the cylinder body, the square piston push rod side of being placed in bush inside, piston mandril is when driving the to-and-fro motion of square piston push rod like this, the square piston push rod can not produce rotation in square lining, thereby effectively prevents piston mandril and piston rod rotation.
