ABSTRACT:
Herein disclosed is a cylinder locking device for locking and stopping the piston rod of a hydraulic cylinder in a desired position. There are fitted rotatably in a housing, a pair of thick, semicylindrical halves which are formed by dividing a thick cylinder having eccentric outer and inner circumferential portions axially into two halves at the thickest and thinnest portions. The piston rod of the hydraulic cylinder is inserted slidably into the inner circumferential portions of the two semicylindrical halves. The piston rod is locked in the desired position by turning the two semicylindrical halves in the opposite directions through a pair of leaves which are attached to the two halves.
