Abstract
The utility model discloses a sheath of a front lifting hydraulic cylinder, which belongs to a shock-absorbing and regulating mechanism, and solves the defects in the prior art that the front lifting hydraulic cylinder is easy to damage and is lack of a protection mechanism. The sheath comprises a guard shield, wherein a top tray is arranged at one end of the guard shield while two ball sockets are arranged at the other end thereof, and the top tray and the ball sockets are respectively fixed on the guard shield; a piston rod jack is formed on the top tray; an upper hinge shaft is arranged on and matched with each ball socket through the spherical surface and can swing at will; a baffle disc is arranged on one side of each upper hinge shaft, fixed on the guard shield, and provided with a groove; and a rubber ring is arranged in each groove. The utility model is mainly used for front lifting mechanisms of various machines.
Description
Technical field
The utility model belongs to a kind of damping controlling mechanism, specifically, relates in particular to a kind of preceding lifting hydraulic cylinder sheath.
Background technique
Preceding lifting hydraulic cylinder in use because stroke is long, belongs to multistage cylinder, has slight vibrations when the oil hydraulic cylinder reducing, and preceding lifting hydraulic cylinder under the situation of unbalance loading, very easily is damaged in installing and using process; Simultaneously, lifting hydraulic cylinder in use broke down before the various error components of existence also can cause.At present, also do not have a kind of damper mechanism to can be good at protecting before lifting hydraulic cylinder make its in the course of the work can be steadily, safety, failsafe.
Summary of the invention
For lifting hydraulic cylinder before solving in the prior art be damaged easily and do not have the defective of protection mechanism, the utility model provide a kind of before the lifting hydraulic cylinder sheath.
The utility model is achieved through the following technical solutions:
Lifting hydraulic cylinder sheath before a kind of comprises guard shield, and an end of guard shield is provided with, and the other end is provided with two ball seats, takes over a business with ball seat to be separately fixed on the guard shield; Take over a business to be provided with the piston rod jack; Ball seat is provided with hinge, and last hinge matches with ball seat by sphere, can swing arbitrarily.
A described side that goes up hinge can be provided with block plate, and block plate is fixed on the guard shield and groove is set, and is provided with rubber ring in the groove.
Compared with prior art, the beneficial effects of the utility model are: preceding lifting hydraulic cylinder has been installed and used the utility model, last hinge can be swung in the certain amplitude scope, rubber ring has compressibility, because the regulating action of last hinge and rubber ring, avoid the contact of rigidity part, thereby reached the effect of buffering and absorbing vibration impact.
