An electric lock includes a housing, a manual control member rotatably affixed to the housing, and a clutch mechanism. The clutch mechanism includes a clutch base rotatably affixed to the housing; a retractable plug arranged on the clutch base, wherein the retractable plug is radially movable relative to the clutch base; a driving member abutting against a first end of the retractable plug; and a motor configured to drive the driving member to move relative to the clutch base toward the shaft of the manual control member.

An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

A locking device including: a locking pin movable in a linear direction; a tappet movable in the linear direction; and a clamping device connecting the tappet to the locking pin. Wherein the clamping device having an inner spring and an outer spring arranged coaxially relative to each other in the linear direction, and the inner spring is at least partially surrounded by the outer spring in a radial direction orthogonal to the linear direction.

An electronic cabinet lock includes a lock housing, a lock body, a limiting member, a motor, and a main control board. The lock body and the limiting member are rotatably disposed in the lock housing, respectively. The motor is electrically connected to the main control board. The limiting member is driven by the motor through a transmission mechanism. The transmission mechanism includes a screw rod driven by the motor and a slider threadedly connected to the screw rod. The slider is slidably disposed in the lock housing, and is movably connected to the limiting member. The transmission mechanism has few components, which is a simple structure and convenient for assembly.

A lock with replaceable modules includes a first part and a second part which is connected to the first part. The lock has a latch bolt recess, a restriction recess and a deadbolt recess so as to selectively install a latch bolt, a restriction bolt and a deadbolt. A lock block is selectively installed in the restriction recess. The lock includes an installation slot which can be selectively oriented in different directions, and a core recess for receiving the deadbolt. The lock is selectively installed with different components by features of modularization and normalization so as to reduce inventory pressure. The customers may install the lock to entrance doors, gate doors, storage room doors, emergency doors, room doors, bathroom doors or the like.

Provided are a lock tongue module and a modular lockset, relating to the technical field of modular locksets. The lock tongue module includes a base, a lock tongue, a lock block, a first elastic member and a second elastic member. The lock tongue is pivotally connected to the base and has a locking position in which the lock tongue is capable of locking a lock catch and an unlocking position in which the lock tongue is capable of releasing the lock catch. The lock block is movably connected to the base.

A latch assembly is provided with a child lock mechanism having a spring system including a first spring member and a separate second spring member that requires a first force to move the child lock mechanism from an off position to an on position and a second force to move the child lock mechanism from the on position to the off position, wherein the required second force is greater than the required first force, thereby indicating to a user by tactile feedback the relative position (on/off) the child lock mechanism is in, thereby assuring intended movement of the child lock mechanism from one of the on/off positions to the other.

The disclosed technology includes a door locking apparatus. In some implementations, the door locking apparatus includes a door stop. In some implementations, the door locking apparatus includes a door block. In some implementations, the door locking apparatus includes a door lock. In some implementations, the door locking apparatus is multi-functional and includes at least one of a door stop, block, and a lock. In some implementations, the door locking apparatus may be operated by a user's foot, although other methods of operation are contemplated. In some implementations, the door locking apparatus may be affixed to either an inside opening door or an outside opening door.

Closing device (1) with a pusher (17), a closing and opening mechanism (7) comprising at least one locking element (9), wherein the at least one locking element (9) movable by means of a latch spring (19) from an open position into a closed is characterized in that the locking spring (19) to assist the closing movement of the at least one locking element (9) in the open position has a first bias voltage by turning the pusher (17) can be generated.
