"Lock Device For Linear Motion Rod"

Abstract: [Problem] To simplify the construction and reduce the size of a lock device that locks a linear motion rod by devising a more rational design structure. [Solution] A lock device having: a brake member that clamps and thereby locks the rod; a piston that releases the locked state by pressing against and opening a pair of pressure receiving parts of the brake member with an expansion member; and an operation element for manually operating the piston. The operating element has a shaft section that is screwed into a screw hole on the main body of the lock device; a pressing plate section formed on one end of the shaft section and positioned inside a pressure chamber; and a seal member provided on the pressing plate section. When the shaft member is screwed into the unlocked position the operating end of the operating element does not protrude from the screw hole and the pressing plate section shifts the piston to the unlocked position. When the shaft section is screwed back to the locked position the operating end protrudes from the screw hole and the seal member of the pressing plate section seals the screw hole and blocks the screw hole from the pressure chamber.
