The invention relates to a triple selecting control locking mechanism for drawer, comprising independence mechanical control mechanism, electrical control mechanism, no-wire remote control mechanism and locking actuator mechanism in common use. The lock bar in mechanical control mechanism is connected with the end of lock core, of which the top end is bending. There are strip hole, R-shaped tappet and kink plate with waist-shaped hole on the unlocking plate. There is limited tappet on the support of unlocking plate and there are control sliding head on the electromagnetic valve fitting in electrical control and no-wire remote control mechanisms. Locking hook and limited chimb are set on the locking hook plate in the locking actuator mechanism. Locking hook member and installing support for spring are set on the installing support for locking hook. Eccentric rotating shaft and limited rotating plate are set between upper and lower seat plate for rotating shaft with limited break at the edge. The limited locking status between locking hook and drawer lock latch is determined by the limited condition of limited break and rotating plate. Triple selecting control method all can control the action of locking actuator mechanism. So it is favor of improving the convenience and safety of operation.
