Abstract
The utility model relates to the technical field of hydraulic lift, particularly relates to a kind of piston of hydraulic lift.The piston of this hydraulic lift comprises guide ring, seal ring and piston, is provided with seal ring in piston, and described seal ring is provided with 3, structure triangular in shape, is provided with guide ring between two seal rings of top.The piston structure of this hydraulic lift is simple, can fully seal, and does not reveal, ensure that stationarity and correctness when ensureing hydraulic transmission.
Description
Technical field
The utility model relates to a kind of piston, particularly relates to a kind of piston of hydraulic lift.
Background technique
Oil hydraulic cylinder is the device pressure energy of hydraulic system being converted into mechanical energy, and in elevating system, the fore and aft motion of piston rod is converted into the lifting of platform by oil hydraulic cylinder by a series of mechanical structure combination, realize lift lifting.In practical operation structure, be provided with piston, mainly play seal action, its sealing effect of existing piston is poor, after the time is long, easily be worn, cause hydraulic transmission easily to be revealed, not only pollute work-yard, limit its application area, may fire casualty be caused, and affect robust motion and the correctness of do-part.
Model utility content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of piston of hydraulic lift.
In order to overcome the defect existed in background technique, the utility model solves the technological scheme that its technical problem adopts: the piston of this hydraulic lift comprises guide ring, seal ring and piston, seal ring is provided with in piston, described seal ring is provided with 3, structure triangular in shape, is provided with guide ring between two seal rings of top.
The beneficial effects of the utility model are: the piston structure of this hydraulic lift is simple, can fully seal, and does not reveal, ensure that stationarity and correctness when ensureing hydraulic transmission.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, guide ring, 2, seal ring, 3, piston.
Embodiment
Fig. 1 is structural representation of the present utility model, and figure comprises guide ring 1, seal ring 2 and piston 3, is provided with seal ring 2 in piston 3, and described seal ring 2 is provided with 3, structure triangular in shape, is provided with guide ring 1 between two seal rings 2 of top.
The inner side of piston 3 has seal ring 2, for sealing, its upper end is provided with 2 seal rings 2, and lower end is provided with 1 seal ring 2, ensures that its sealing is oil-proof, between 2 seal rings 2 of upper end, places guide ring 1, and overall structure is simple, good sealing effect.
The piston structure of this hydraulic lift is simple, can fully seal, and does not reveal, ensure that stationarity and correctness when ensureing hydraulic transmission.
