A hand wheel locking device for an actuator

Abstract

The utility model relates to the field of actuator, concretely relates to a hand wheel locking device of actuator, including a hand wheel seat, and with the cooperation of hand wheel seat, the clamping block of hand wheel axle forms the clamping effect, still including screw, and with the spring of screw is supported, screw passes through hand wheel seat, spring, clamping block in proper order, will hand wheel seat with clamping block fixed, make spring set up between hand wheel seat and clamping block, for the tensioning force of continuously exerting between hand wheel seat and clamping block, to control the clearance size of hand wheel seat and clamping block. The device can lock the hand wheel axle in the non -use state, prevent the displacement due to the false touch, realize simple, convenient operation while possessing easy processing, easy installation's characteristics, can be quickly added to the actuator hand wheel of existing not equipped locking device, thereby reduce the cost of equipment safety upgrade.
