An electronic lock cylinder that may be a direct replacement for a European-style standard cylinder is disclosed. The lock cylinder may include a core, a first shaft rotatably mounted in the core, and a second shaft rotatably mounted in the core and coaxial with the first shaft. A first cam and a second cam may be each rotatably mounted in the core and coaxial with the first shaft. The first cam may include a first lug and the second cam may include a second lug, where the first lug and the second lug may each be coupled to a deadbolt. A clutch may be disposed on the first shaft and shiftable from a first position to a second position, and a motor may be disposed in the core and operatively coupled to the clutch and configured to shift the clutch from the first position to the second position. When the clutch is in the first position, the first shaft is operatively coupled to the first cam, and the second shaft is decoupled from both the first cam and the second cam, when the clutch is in the second position, both the first shaft and the second shaft are operatively coupled to the second cam.

A clutch assembly of an electronic cabinet lock includes a cam, a camshaft, a gear disc, a sleeve, a snap ring, and a steel ball. The cam includes a sleeve ring at its inner end and a swing arm at its outer end. The camshaft is sleeved within the sleeve ring by clearance fit, and the sleeve ring is sleeved within the sleeve by clearance fit. The gear disc is sleeved on the outer wall of the sleeve. The steel ball is mounted in a through groove of the side wall of the cam. The steel ball is located between the sleeve and the cam and is tangent to the camshaft. The camshaft is provided with a groove, and the groove allows the steel ball to fall in. The snap ring is engaged in an annular groove of the lower end of the camshaft for restricting the sleeve.

A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.

A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

Disclosed is a Bluetooth smart padlock, including a lock housing, a lock beam, a lock tab assembly, a power assembly and a sensing switch. The lock housing is provided with a Bluetooth module for establishing a communication with a mobile terminal and a controller electrically connected with the Bluetooth module; the lock beam is partially provided in the lock housing, and provided with a lock tab groove; a lock tab assembly and a power assembly are both provided in the lock housing, wherein the lock tab assembly comprises a lock tab piece, and the power assembly is in transmission connection with the lock tab piece to drive the lock tab piece to extend into or separate from the lock tab groove, to unlock or lock the lock beam; and the sensing switch is provided on the lock housing for controlling the power assembly.

A cylindrical door lock including a latch bolt, a cam assembly operable to move the latch bolt from a first position to a second position, a support at least partially surrounding the cam assembly, an operator actuatable input device operatively coupled to the latch bolt through the cam assembly, a retainer coupling the operator actuatable input device to the support and being moveable between a hold position and a remove position, a removable lock core positioned at least partially within the operator actuatable input device, a throw member operatively coupled with the lock core and the cam assembly to actuate the cam assembly based on a position of the operator actuatable input device, and a stabilizer positioned at least partially within the support and posterior to the lock core.

A cooler and freezer access control system locks a cooler or freezer when occurrence of an event is detected that requires limiting access to the inside of the cooler or freezer. Examples of such events include the loss of power to the cooler or freezer for a predetermined period of time, the opening of the cooler or freezer door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler or freezer door open while stocking the cooler or freezer with product.

A smart lock for securing a door is provided comprising: an actuator configured to actuate a lock mechanism between a locked and an unlocked position; a housing attachable to a first side of the door, retaining the lock mechanism and the actuator; a receiver configured to wirelessly receive a signal to control operation of the actuator; a key mechanism engageable with the lock mechanism so as to actuate the lock mechanism, the key mechanism for receiving a tail piece of a key cylinder; a handle mechanism engageable with the lock mechanism so as to actuate the lock mechanism; and a handle arranged to control operation of the handle mechanism extending from the housing on the first side of the door. The key mechanism and the handle mechanism are disengageable from the lock mechanism.
