The inside of hydraulic cylinder is located at, the upper and lower ends of the bushing are respectively arranged with non-abutting end and abutting end, and the bushing is by damping
Layer, wearing layer and blotter coat are constituted, and blotter coat is located between buffer layer and wearing layer, and the inside of the wearing layer, which is offered, matches somebody with somebody
Cavity is closed, the top of the cooperation cavity is fixed with the first oil-scraping ring and the second oil-scraping ring, and the first oil-scraping ring is fixed on second
The upper end of oil-scraping ring.
It is preferred that, the top of the hydraulic cylinder is closely connected with end cap by screw thread.
It is preferred that, the bottom of the movable cylinder is provided with rodless cavity, and rodless cavity is arranged on the inside of hydraulic cylinder.
It is preferred that, the right-hand member of the hydraulic cylinder offers hydraulic cylinder hydraulic fluid port.
It is preferred that, the bottom of the non-abutting end is bonded with seal washer.
It is preferred that, the outer surface of the buffer layer is provided with external screw thread.
It is preferred that, it is described to coordinate cavity and the bottom gap of damper connecting rod to coordinate.
Compared with prior art, the beneficial effects of the utility model are：The design of the equipment wearing layer, adds bushing
Anti-wear performance, both ensure that prolonged cooperation was required, service life is added again, use cost is reduced；Buffer layer is set
Meter, the vibrations occurred when can be worked with absorption plant, it is ensured that the normal operation of mechanism；The design of blotter coat is used, to wearing layer
Certain lubrication is played, set of service life is improved；First oil-scraping ring and the second oil-scraping ring can connect damper
The unnecessary hydraulic oil in extension bar end is scraped can be in hydraulic cavities, it is to avoid the leakage of hydraulic oil or spilling；Equipment overall structure design is closed
Reason, cost are low, service life is longer, with higher practicality.
