An electric strike lock is disclosed. The electric strike lock cooperates with a lock when in use. The lock has a lock tongue. The electric strike lock includes a base. The base has an opening for accommodating the lock tongue. The base has a pair of grooves corresponding to two opposite sides of the opening. Two sliding members are slidably disposed in the respective grooves. The sliding members are connected with at least one driving unit for the sliding members to slide closer to each other so that the lock tongue is engaged in the opening, or for the sliding members to gradually slide away from each other so that the lock tongue is disengaged from the opening, thereby performing locking and unlocking operations on a door in a sliding manner.

This document discloses a storage device for theft-proof storage of valuable articles, comprising a cabinet, having at least one drawer space, a safe drawer, which is received in the drawer space, a safe housing, comprising side walls and a top wall connecting the side walls, wherein the safe drawer is slidably connected to the safe housing and wherein the safe housing is mounted to the cabinet in the drawer space, a locking member, which is movably connected to the safe drawer or to the safe housing, an actuator, which is operatively connected to the locking member, for controlling a movement of the locking member, and a controller, which is operatively connected to the actuator, and which is configured to control the actuator. The controller is configured for receiving a control signal, based on which the controller is configured to control the actuator. The locking member is movable between a first position, in which the locking member locks safe drawer relative to the cabinet, and a second position, wherein the safe drawer is unlocked relative to the cabinet.

An intelligent door lock system is coupled to a door at a dwelling. A first sensor is at the dwelling. The first sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. The lock device is coupled to the first sensor and the lock device includes a bolt. An engine, an energy source and a memory are coupled together. A magnetic sensor provides a reading or measurement used to determine a door open or closed status.

Security systems and methods are provided. In one example, a security system includes at least one lock configured to protect one or more items from theft from the fixture, wherein the lock comprises a plunger pin configured to be moved between a latched position and an unlatched position, and wherein the fixture is configured to be accessed in the unlatched position. The lock comprises a cam configured to be moved between a locked state and an unlocked state for allowing the plunger pin to be moved between the latched position and the unlatched position when in the unlocked state, wherein the cam is configured to be moved in response to receiving a wireless authorization signal to transition the lock between the locked state and the unlocked state.

The present disclosure relates to an auto-open door lock apparatus including a main body cover having a space therein, and a motor installed inside the main body cover to provide a driving force, the auto-open door lock apparatus comprising: a locker which is coupled to or separates from a hook that is introduced from the outside through rotation; a locker shaft having one end connected to the locker, and formed in the center of rotation of the locker; a clutch gear connected to the other end of the locker shaft to induce rotation of the locker; a locker spring connected to one side of the locker to provide a rotational restoring force to the locker; a rack slide which provides a rotational force of the motor to the locker through the clutch gear; and a pinion gear which transmits the rotational force of the motor to the rack slide.

A door lock apparatus according to an embodiment of the present invention is mounted in a door and moves a deadbolt to a locked position or a released position as a motor is driven. The door lock apparatus may include a main gear rotated by the motor, a damping clutch part engaged and rotated by rotation of the main gear, a shaft which is engaged and rotated by rotation of the damping clutch part and moves the deadbolt as the shaft is rotated, and a knob which is manually operable by a user and is connected to the shaft. An emergency rotation operation of the shaft may be enabled by disengaging the main gear and the damping clutch part through the knob.

A transmission mechanism of an electromechanical lock includes a first rotating wheel and a rotatable structure. The first rotating wheel has a recessed portion and two first protruding portions. The recessed portion is arranged in a center of the first rotating wheel, and the two first protruding portions are separated from each other and protrude from a side surface of the recessed portion. The rotatable structure is arranged in the recessed portion. The rotatable structure includes a rotatable portion and two elastic members. The rotatable portion is rotatably arranged in the recessed portion. The two elastic members are separated from each other and connected to the rotatable portion, in which each of the elastic members has a second protruding portion close to the side surface of the recessed portion and is configured to interfere with each of the first protruding portions.

A locking module for selectively coupling a first component and a second component of a lockable device includes a locking member rotatable about an axis between a rest position and an actuated position. An engagement member is movable between a locked position and an unlocked position. The engagement member is configured to cooperate with the locking member to selectively release the second component.

An intelligent lock guard device, including a box body, the box body includes an upper box cover and a lower box body being buckled to form a hollow box body; the protection lock, including a lock catch and a lock body mechanism; the lock catch includes a fixing crossbeam and a locking rod, the fixing crossbeam is fixed on the upper box cover, and the locking rod is provided with a locking hole; the locking body mechanism, including a lock shaft, a toothed belt and a motor; the locking body mechanism is fixed on the lower box body; the lock shaft is provided with a lock cylinder convex bar, and the track of the toothed belt is parallel to the direction in which the lock cylinder convex bar is inserted or removed from the locking hole.
