Abstract

The utility model discloses a kind of band X sealing configuration oil cylinder, comprise cylinder body (2), piston rod (1), seal ring, end cap seat and end cap, it is characterized in that: seal ring (5) is X-shaped structure, inside X-shaped seal ring lip limit, lips limit and piston rod (1) cylindrical are close to, X-shaped sealing ring one side end face is close on end cap seat (3), and opposite side end face is close on end cap (4).Band X sealing configuration oil cylinder usability is better, long service life, greatly can extend oil cylinder working life.

Description

A kind of band X sealing configuration oil cylinder
Technical field
The utility model relates to a kind of hydraulic jack component, especially a kind of oil cylinder with X sealing configuration.
Background technique
Oil cylinder is the vitals of hydraulic system.Promote piston by hydraulic oil to move axially and implement linkage and enter and the action such as to move back, because hydraulic jack moves reciprocatingly for a long time, frequency of utilization is very high, very easily cause piston rod and ring wear serious, when after piston rod wearing and tearing to a certain degree, will leakage of oil, cause whole hydraulic parts to work, whole hydraulic parts can only scrap process.Due to the uncompensated sealing function of existing cylinder seal, cause whole hydraulic parts shorter for working life, especially in bad working environments environment, working life is shorter, has the hydraulic jack repairing remedial measure to be very necessary after therefore developing a kind of effective adaptation bad working environments environment, piston rod wearing and tearing.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of with compensation sealing function, the oil cylinder improving hydraulic parts working life, band X sealing configuration.The purpose of this utility model is realized by following technical proposals: the utility model comprises oil cylinder, piston rod, seal ring, end cap seat and end cap, it is characterized in that: seal ring is X-shaped structure, inside X-shaped seal ring lip limit, lips limit and piston rod cylindrical are close to, X-shaped sealing ring one side end face is close on end cap seat, and opposite side end face is close on end cap.
The utility model adopts X structure, after installing, piston rod cylindrical is close in bottom, medial lip limit, X-shaped seal ring lip limit, good seal performance, grease can not flow out, and X seal ring axial vane surface is compressed, after end face compresses by end cap seat and end cap, after medial lip limit, X-shaped seal ring lip limit is stressed, to piston rod extruding, no matter whether diameter of piston rod diminishes and is close to all the time inside such X-shaped seal ring lip limit, can not leakage of oil.The utility model band X sealing configuration cylinder seal performance is good, although piston rod wearing and tearing, because this X-shaped seal ring is by after axial force, medial lip limit, lip limit (lips limit) is close to above piston rod, stops hydraulic fluid leak.Compared with prior art, band X sealing configuration oil cylinder performance is better, has stronger sealing compensation function, long service life, greatly can extend the working life of hydraulic jack.From above-mentioned situation, the purpose of this utility model can realize.
Accompanying drawing explanation
Fig. 1 is the utility model structure, mounting point schematic diagram.
Embodiment
As shown in Figure 1, the utility model comprises cylinder body (2), piston rod (1), seal ring, end cap seat and end cap, it is characterized in that: seal ring (5) is X-shaped structure, inside X-shaped seal ring lip limit, lips limit and piston rod (1) cylindrical are close to, X-shaped sealing ring one side end face is close on end cap seat (3), and opposite side end face is close on end cap (4).

Claims (1)
