| description | A hydraulic locking cylinder capable of regulating locking force belongs to the hydraulic locking technical field. The technical problem to solve is to provide a hydraulic locking cylinder which has the conveniently adjustable locking force, can easily achieve biggest locking force and releases the pre-tension force of a spring when repaired. The structure of the utility model comprises a cylinder body, pistons, the spring; the improvement of the utility model is as follows: the spring is arranged between the two pistons, an adjusting pad is arranged at the end of a piston rod, the two ends of the adjusting pad contact with the piston rob and a baffle holder respectively, oil holes are arranged at two ends of the cylinder body. On the premise of reserving the advantages of the prior locking device, the utility model overcomes the shortcoming that the locking force is not easy to adjust and to gain biggest locking force, can be locked on needed number after adjusting the locking force and can improve the using performance of the locking device. The utility model can eliminate the pre-tension force basically without the effect of liquid force, can disassemble, detect and repair an oil cylinder without special facilities, is convenient to repair and use for the users; and the utility model is applicable to the working places where various sorts of locking are needed, in particular for locking device of a rolling mill. |
