The invention relates to an improved locking device for the closure of doors on cabinets, of boxes or compartments, which offers high resistance to unauthorized attack and, in particular, can take up high torques. For this purpose, use is made of a coupling arrangement having a manually or electronically movable actuating member, a driver (), which interacts with the actuating member, and a blocking member (). The blocking member () has the form of a cylinder, the cylinder axis of which runs parallel to the rotor axis (). The blocking member () in its blocking position engages in a depression () on the outer side of the rotor () or in a depression () on the inner side of the wall () of the stator () and is held in this blocking position by spring force.

Locking device

The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle () is connected to the rotor () so as to transmit a torque and is held on the rotor () by a clamping spring (). The clamping spring () has a receiving area for a magnet (). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle () and the rotor () is triggered by an external influence on the magnet () (FIG.).
