A laminated padlock comprises a laminated padlock body formed by laminating a plurality of lock sheets, a lock core assembly, and a lock beam connected with the top of the laminated padlock body. The lock core assembly comprises a first lock tongue, a second lock tongue, a large frame, a small frame, a lock core shaft and cipher wheels; the large frame is provided with a positioning resilient piece, and the lower end of the large frame is provided with a limiting plate with a limiting chuck; shaft holes; the small frame is provided with a small resilient piece, and a branch plate is arranged below. The laminated padlock achieves dual guarantee, perfectly solves the defect that the ciphers can be changed by a cipher adjusting rod under the condition of not knowing the ciphers when the lock beam is opened and greatly enhances the safety performance of the laminated padlock.

Systems and methods for controlling access to a secured space are disclosed. The system includes a locking device fastenable to an access point of the secured space, a server, and a network for communication between the locking device and server. The locking device includes an actuator, a memory, and a processing unit for generating a control signal for the actuator to move the locking device into a locked state or a closed state. The server includes a storage unit to store authorization data for the locking device, and a processing unit which can receive a security request for the locking device from a user computing device; determine whether the security request includes requesting data that corresponds to the authorization data stored for the locking device; generate a security command based on the security request; and communicate the security command to the locking device.

An electric lock system, includes an electric lock and an electric key. The electric lock includes a lock body and a lock core, and the lock body has a key limit slot and a key limit slide. The lock core includes a T-shaped magnet, a solenoid and a lock pin. The T-shaped magnet is fixed to the lock core, and the lock pin is connected to the solenoid, the solenoid can generate a magnet field when energized, and the magnet field generate a force with the T-shaped magnet, and drives the lock pin to stop limiting the lock body. The electric key includes a lithium battery and a metal housing, and the metal housing has a key limit head corresponding to a shape of the key limit slot. The electric key provides electric power to the lock core by contacting the key limit head to the key limit slot.

Moto-controlled lock apparatus/mechanism that deploys locking pins to retain the shackle when the lock apparatus/mechanism is in the closed position. Generally, when the lock apparatus/mechanism is in the closed position, the locking pins are prevented from moving by a blocking cam. In various embodiments, the blocking cam is actuated by a motor that rotates the blocking cam, thereby forcing the locking pins into and holding the locking pins in compatibly-shaped cutouts in the shackle.

An electronic sensor and key operated lock is disclosed which provides users with the option to use at least one of a manually operated mechanism or for example a biometric sensor to unlock the lock. The lock integrates both the manually operated mechanism and a biometric sensor into one device. The manually operated mechanism and a biometric sensor are coupled to a common toggle switch so that operation of at least one of the manually operated mechanism and the biometric sensor moves the toggle switch and a shackle from locked and unlocked positions.

An electronic straight shackle lock apparatus and system. Aspects of the present disclosure provide for a keyless, electronic straight shackle lock that provides a high level of security at a relatively low cost and without any opening for a physical mechanical key. Certain embodiments provide for an easy-to-use and compact adapter for a keyless, electronic straight shackle lock and the ability to manually override the electronic lock. Certain benefits and advantages of the present disclosure include a compact and flexible locking system that can be installed on many different enclosures and doors that can be locked and unlocked using an electronic device via a wireless signal.

An electronic lock includes a lock body and a shackle selectively securable via one or more ball bearings. An asymmetric cam can be rotated by a key or an electric motor to: a locked state in which the ball bearing secures the shackle within the lock body via at least one lock notch in the shackle, an unlocked state in which the ball bearing is released from the lock notch to unlock the shackle and subsequently engages a revolved notch on a distal end of the shackle to prevent removal of the shackle from the lock body, and a removal state in which the ball bearing is released from the lock notch and the revolved notch to allow the shackle to be removed from the lock body. A shackle detector can detect a shackle in the locked state. Externally accessible electrical contacts allow for jumpstarting a discharged battery.
