A cabinet lock for securing a door panel to a cabinet housing comprising a latching component, an electromechanical component, and a communications module. The latching component has a latch housing and latch member reciprocally translatable between locked and unlocked orientations to selectively secure the door panel to the cabinet housing. The electromechanical component includes an actuator operably coupled to a drive member that is coupled to the latch member whereby powering of the actuator translates the latch member to at least one of the unlocked or locked orientations. The communications module is configured for communication with a remote device of a municipal traffic control agency and/or a utilities worker. The communications module is configured to receive a control signal from the remote device for moving the latch member to the at least one of the unlocked orientation or the locked orientation.

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 illustrative motor drive assembly is configured for use in a lockset comprising a case, a longitudinally movable link, and a catch configured to move among a locking position and an unlocking position in response to longitudinal movement of the link. The illustrative motor drive assembly includes a longitudinally extending shaft comprising a worm, a motor operable to rotate the shaft, a driver engaged with the worm, and a longitudinally extending spring. The spring is not directly engaged with the worm, and includes a first end coupled with the driver and a second end connectable with the link. Engagement between the worm and driver is configured to longitudinally move the driver in response to rotation of the shaft.

A telescopic electromechanical dual-control smart lock includes: a lock cylinder mechanism, a transmission mechanism and a power supply control mechanism; wherein the lock cylinder mechanism comprises a bolt, a lock core PCB (printed circuit board), a positive electrode sheet, a negative electrode sheet and a first spring; the power supply control mechanism comprises a main control PCB and a detachable battery; wherein the positive electrode sheet, the negative electrode sheet and the transmission mechanism are electrically connected with the lock core PCB respectively; wherein a first end of the transmission mechanism is pressed against an end of the first spring; a second end of the transmission mechanism is fixedly connected with the bolt; is the lock cylinder mechanism and the transmission mechanism are provided side by side, and the main control PCB is electrically connected with the lock core PCB and the detachable battery respectively.

An electronic lock includes a latch member and a clutch mechanism mounted on the outside of the lock cylinder and including a clutch unit, a driving unit and a control module. The clutch unit includes a rotatable seat having a first engaging portion, an accessible knob, and a clutch seat having a second engaging portion. The clutch seat is movable relative to the rotatable seat between an unlock position and a lock position, where the second engaging portion engages and disengages the first engaging portion, respectively.

A motorized latch retraction system for transitioning a latch of an exit device from a latched position to an unlatched position is provided. The motorized latch retraction system includes a lock indicator indicating the latched or unlatched position of the latch and a floating motor.

An illustrative motor drive assembly is configured for use in a lockset comprising a case, a longitudinally movable link, and a catch configured to move among a locking position and an unlocking position in response to longitudinal movement of the link. The illustrative motor drive assembly includes a longitudinally extending shaft comprising a worm, a motor operable to rotate the shaft, a driver engaged with the worm, and a longitudinally extending spring. The spring is not directly engaged with the worm, and includes a first end coupled with the driver and a second end connectable with the link. Engagement between the worm and driver is configured to longitudinally move the driver in response to rotation of the shaft.

A screw-driven control system includes a driving mechanism fixed in a cross beam, a guide locking piece and a limiting mechanism. The driving mechanism includes a screw rod and a motor driven nut assembly having a transmission frame, a nut sleeved in the screw rod, and a follow-up member fixed in the nut; the nut is mounted in the transmission frame, and the transmission frame is connected with a controlled object; the screw rod drives the nut assembly to reciprocate axially along the screw rod.

An arrangement (10) for a lock device (88a, 88b), the arrangement (10) comprising an input member (12, 106); a coupling member (26) movable between an uncoupled position (34) and a coupled position (80); an electromechanical actuator (28) comprising an actuating member (42) linearly movable between an uncoupling actuating position (44) and a coupling actuating position (78); and a torsion spring (30) having a first leg (62) and a second leg (64) movable away from each other against a deformation of the torsion spring (30), wherein the actuating member (42) is arranged to engage the first leg (62) and the second leg (64) is arranged to engage the coupling member (26) when the coupling member (26) is in the uncoupled position (34) and the actuating member (42) moves from the uncoupling actuating position (44) to the coupling actuating position (78). A lock device (88a, 88b) comprising an arrangement (10) is also provided.

A wirelessly controlled blocking apparatus to enable a single-point locking system for securing multiple access points on a cabinet panel. Certain aspects of the present disclosure provide for a wirelessly controlled blocking apparatus to enable a single-point locking system for securing multiple access points. In accordance with certain embodiments, the wirelessly controlled blocking apparatus is utilized to secure an access panel of an enclosure, such as an electronics cabinet. In accordance with certain preferred embodiments, an electronics cabinet comprises a plurality of quarter-turn cam latches being installed on the access panel and configured to selectively secure the access panel to an opening of the enclosure.
