First anti-skidding projection is positioned at first annular sealing lip away from annular seal body side；Second annular seal lip leans on
The side of nearly first annular sealing lip is provided with the second anti-skidding projection, and the second anti-skidding projection is positioned at the second ring packing
Lip is away from annular seal body side.
This utility model uses polyurethane material to produce, first annular sealing lip and the second annular during use
There is between sealing lip enough spaces deform upon for first annular sealing lip and the second annular seal lip, have
It is beneficial to reduce the requirement of this utility model machining accuracy and improve sealing effectiveness of the present utility model, utilizes and reset
The elastic tension force increasing product of the reset capability compounding ingredient of part itself, increases its seal and pressure bearing power.This reality
Simple with new structure, easy to use and good sealing effect.
Accompanying drawing explanation
Fig. 1 is a kind of oil cylinder high pressure reciprocating seal ring sectional view that the utility model proposes.
Detailed description of the invention
With reference to shown in Fig. 1, a kind of oil cylinder high pressure reciprocating seal ring that the utility model proposes, including annular
Sealed body 1 and return unit 2；
First annular sealing lip 3 and the second annular seal lip 4 are installed in annular seal body 1, first annular
Sealing lip 3 and the second annular seal lip 4 be positioned at annular seal body 1 axially on the same side, first annular
Sealing lip 3 is gradually distance from annular seal body 1 axis along the direction away from annular seal body 1, and second
Annular seal lip 4 is positioned at first annular sealing lip 3, and the second annular seal lip 4 is along away from ring packing
The direction of main body 1 moves closer to annular seal body 1 axis；
Return unit 2 is arranged in annular seal body 1, and is positioned at first annular sealing lip 3 and the second annular
Between sealing lip 4.
This utility model uses polyurethane material to produce, first annular sealing lip 3 and the second ring during use
There is between shape sealing lip 4 enough spaces occur for first annular sealing lip 3 and the second annular seal lip 4
Deformation, advantageously reduces the requirement of this utility model machining accuracy and improves sealing effectiveness of the present utility model,
Utilize the elastic tension force increasing product of the reset capability compounding ingredient of return unit 2 itself, increase its sealing and hold
Pressure.This utility model simple in construction, easy to use and good sealing effect.
In present embodiment, return unit 2 is spring, and spring not only production cost is low, has sufficient deformation
Space, and be conveniently replaceable.
In present embodiment, annular seal body 1 is also equipped with the first sealing and strengthens ring 5 and the second sealing
Strengthening ring 6, the first sealing strengthens ring 5 and the second sealing strengthens ring 6 and is separately mounted to annular seal body 1
Inner periphery and the outer periphery, further sealing effectiveness of the present utility model.
In present embodiment, annular seal body 1, first annular sealing lip the 3, second annular seal lip 4,
First sealing strengthens ring 5 and the second sealing strengthens ring 6 and is wholely set, and is conducive to the heavily fortified point of raising present configuration
Solidity.
In present embodiment, annular seal body 1 is internally installed reinforcing annular pipe 7, it is to avoid this utility model
