Description

Cylinder piston structure-improved
Technical field
The utility model relates to a kind of cylinder piston structure-improved.
Background technique
Often piston structure is combined with on cylinder uses, piston structure comprises a piston, a piston ring, piston ring is except the effective sealing that need keep between piston and cylinder, also must do the motion in three directions, i.e. axial motion, radial motion and circular movement, so load and frictional loss are quite large, cause its working life not long, have much room for improvement part really.
Summary of the invention
In order to overcome defect of the prior art, the utility model provides a kind of cylinder piston structure-improved.
The utility model solves the technological scheme that its technical problem adopts: the utility model provides a kind of cylinder piston structure-improved, comprises a piston, piston ring, seal ring, pad and piston rod.
Piston has the first relative end face and the second end face, and having circumferential surface in first and second end face periphery with fillet linking, this circumferential surface is arranged with an outer groove, and the center of first and second end face is run through axis hole, be arranged with a tank in the first end face, tank coaxially connects with axis hole; Piston ring is installed on outer groove, and the just symmetrical outstanding piston circumferential surface of external diameter; Seal ring is installed on tank, and the proper symmetry of seal ring internal diameter charges into axis hole scope; Pad is connected to the first end face, and pad has the jack relative with axis hole, and makes the first class being formed with clitellum shape between pad periphery and piston first end face; Piston rod coaxially extends one and inserts axle, slotting axle penetrates jack, seal ring internal diameter and axis hole, insert axle the inner and form the shoulder that can abut pad, and be provided with in slotting axle outer end the block edge that is connected to piston second end face, make between this block edge periphery and piston second end face and be formed with clitellum shape second class.
The beneficial effects of the utility model are: reduce the stressed and abrasion situation of piston ring, effectively extend the working life of piston ring, reduce user cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is exploded pictorial Fig. 1 of the present utility model.
Fig. 2 is exploded pictorial Fig. 2 of the present utility model.
Fig. 3 is overall schematic of the present utility model.
Fig. 4 is generalized section of the present utility model.
1. pistons, 2. piston ring, 3. seal ring, 4. pad, 5. piston rod in figure, 6. the first end face, 7. the second end face, 8. circumferential surface, 9. outer groove, 10. axis hole, 11. tanks, 12. jacks, 13. insert axle, 14. shoulders, 15. block edges.
Embodiment
As shown in Figures 1 to 4, the utility model provides a kind of cylinder piston structure-improved, and comprise a piston 1, piston ring 2, seal ring 3, pad 4 and piston rod 5, concrete structure is as follows.
Piston 1 has the first relative end face 6 and the second end face 7, and have circumferential surface 8 in first and second end face periphery with fillet linking, this circumferential surface 8 is arranged with an outer groove 9, the center of first and second end face is run through axis hole 10, be arranged with the large tank 11 of an aperture axis hole 10 in the first end face 6, tank 11 coaxially connects with axis hole 10.
Piston ring 2 is installed on outer groove 9, and external diameter symmetrically be able to give prominence to piston 1 circumferential surface 8, and can do axial motion along outer groove 9.
Seal ring 3 is installed on tank 11, makes seal ring 3 internal diameter symmetry be able to charge into axis hole 10 scope.
Pad 4 is connected to the first end face 6, and in order to locating sealing ring 3, make seal ring 3 cannot deviate from tank 11, pad 4 has the jack 12 relative with axis hole 10, and makes the first class being formed with clitellum shape between pad 4 periphery and piston 1 first end face 6.
Piston rod 5 coaxially extends one and inserts axle 13, insert axle 13 and penetrate jack 12, seal ring 3 internal diameter and axis hole 10, insert axle 13 the inner and form the shoulder 14 that can abut pad, and be provided with in slotting axle 13 outer end the block edge 15 that is connected to piston 1 second end face 7, make between this block edge 15 periphery and piston 1 second end face 7 and be formed with clitellum shape second class.
In use, piston 1 is when moving along cylinder as axial linear, and first and second class of clitellum shape can produce corresponding turbulent flow further, and this turbulent flow can reduce the stressed and abrasion situation of piston ring 2, so just effectively can extend the working life of piston ring 2, reduce user cost.
