Abstract
The utility model discloses a sliding hydraulic cylinder end cover which comprises a cover body, wherein the center of the cover body is provided with a center hole, the inner side of the center hole is provided with a guide hole, the outer side of the cover body is fixedly connected with a location block, and the location block is provided with a plurality of location screw holes; and the cover body positioned on the outer side of the guide hole is provided with an annular groove. The sliding hydraulic cylinder end cover has the beneficial effects that the annular groove is formed in the position close to the center hole, thus the stability of connecting the sliding hydraulic cylinder end cover with a sliding cylinder body is favorably improved when the sealing ring is sleeved as required; and through arranging the location block, the sliding hydraulic cylinder end cover is conveniently assembled with the end part of a piston rod so that the sealing property of the end part of the piston rod is greatly improved, and the sliding hydraulic cylinder end cover is durable.
Description
Technical field
The utility model relates to cylinder component, relates in particular to a kind of slip oil hydraulic cylinder end cap.
Background technique
Hydraulic cylinder structure generally is made up of cylinder barrel, cylinder cap, piston, piston rod, seal arrangement, damping device etc.Protecgulum wherein is the sealing of closed piston rod end head position to guarantee that it is basic, so major applications is in oil cylinder, cylinder moving power unit.Front cover portion should possess good sealing property and can combine common activity performance and the sealability that improves piston body with remaining component; Existing similar protecgulum lacks the groove of sealing configurations such as being used for setting sleeve, packing ring or seal ring, therefore need make improvements.
The model utility content
To above defective, the purpose of the utility model provide a kind ofly improve the whole tightness of oil cylinder, be convenient to assemble with the position, piston rod end, durable, the slip oil hydraulic cylinder end cap being convenient to safeguard, to solve many deficiencies of existing technology.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of slip oil hydraulic cylinder end cap comprises lid, and said lid center position is provided with center hole, and this center hole inboard is provided with bullport, and the said lid outside is fixedly connected positioning block, and this positioning block is provided with some positioning screw holes; Be positioned on the lid in the bullport outside and offer an annular groove.
The beneficial effect of the described slip oil hydraulic cylinder of the utility model end cap is: through in offering an annular groove near the central hole location place, help when needed improving itself and slippage cylinder body connection stability through being inserted in seal ring; Through positioning block is set, be convenient to assemble that the sealability that makes the piston rod end improves greatly, durable with the position, piston rod end.
