A dual padlock includes a shell, a bolt, a button, a combination lock core, a key lock core, and a linking element supported on the shell. The key lock core is inserted in the button, rotatable relative to the button, and moveable linearly along the button. The linking element is moveable by the key lock core when the key lock core is rotated relative to the button and when the key lock core moves linearly with the button. The bolt is moved by the linking element when the linking element is moved. The bolt shuts the first opening of the shell when the bolt is in a closing position. The bolt opens the first opening of the shell when the bolt is in an opening position.

A USB combination lock for an electronic device may include a lock rod, a shell body, a USB connector, a push button, and a lock piece. The USB connector can be directly inserted into the USB port of the electronic the electronic device, and the blocking portion of the USB connector can be engaged with the USB port. When the push button is in a released position, the lock piece will block a bottom portion of the hooking member of the USB connector, and the lock piece will not be pressed inwardly by the blocking portion. Thus, by shifting the numeral wheels, the connecting piece can be turned into the lock position, leading to the combination lock of present invention achieving the burglarproof effect.

A combination lock has a body formed from a stack of plates each having various openings to form some of the channels or holes such as the locking hole to receive the short leg of the shackle, the long-leg channel, the spindle hole, the dial slots, the ratchet-pin holder slot and the bolt slots. The short leg and the long leg of the shackle each has a cutout to receive a locking bolt. The spindle has a locking surface to engage the locking bolts with the cutouts when the lock is in locked mode. The spindle also has a neck to release the locking bolts from the cutouts when the lock is in opened mode. The lock has a directional plate and a reset button near the lock's bottom end to control the rotation and the downward movement of the spindle in the reset mode.

The disclosure generally relates to a system and method for managing distributed encrypted combination over-locks from a remote location. In an exemplary embodiment, the invention is a distributed management system for self-storage facilities that allow for vacant units to be secured with over-locks, and which allow the over-locks to be removed by customers without human or manual intervention from the self-storage facility, where an API is used to facilitate communications between a lock management system and a property management system.

A lock for securing a computer with a computer slot, is disclosed. The lock includes a locking head with a fixed locking arm, a rotatable locking arm, a control link operably connected to the rotatable locking arm and configured to translate along a longitudinal axis of the locking head, and a biasing element that provides a resistive force or torque against the rotatable locking arm when the lock is in a locked configuration.

A lock has a cable engageable with a lock body. The cable has two ends, each of which has a cable neck. The lock has a shaft operatively engaged with a stack of clutches and a plurality of dials. The shaft has a top portion with a shaft slot engageable with the cable neck on the first cable end. The first cable end can be released from the lock body with a combination mechanism. The lock has a fixed cam having a cam slot engageable with the cable neck of the second cable end. The lock further comprises a blocking plate slideably engaged with the fixed cam, and a rotatable cam configured to control the positions of the blocking plate. The rotatable cam is connected to a cylinder operable with a key to rotate the rotatable cam to release the second cable end from the fixed cam slot.

A lock has a hook and a locking finger to form a locking loop. The hook is fixedly attached to the lock body, whereas the locking finger can be pivoted to disengage from the hook to open the lock. The pivotal movement of the locking finger is controlled by a latch and an extended edge. The latch has a tip and the locking finger has a cut-out to receive the tip when the lock is locked. When the lock is locked, a spindle prevents the extended edge from moving toward the latch for releasing the tip from the cut-out. When the lock is opened by the combination mechanism, the spindle is moved away to allow the extended edge to move toward the latch to release the tip from the cut-out. When the lock is opened by the key mechanism, turning the cylinder causes the extended edge to move the latch downward.

The present disclosure provides an alarming code lock, including a lock head and a steel wire rope. A warning device, a circuit board, and a trigger switch are disposed inside the lock head. The warning device and the trigger switch are electrically connected with the circuit board. One end of the steel wire rope is fixedly connected with the lock head and is electrically connected with the circuit board. A plug is disposed on another end of the steel wire rope. The plug is inserted into the lock head and then makes contact with the trigger switch. The steel wire rope and the circuit board form a protection circuit, and the warning device is configured to raise an alarm when the plug keeps in contact with the trigger switch and the protection circuit is disconnected.

A joint lock comprises a lock body that accommodates a combination locking mechanism; and a jointed bar hoop. The combination locking mechanism has a plurality of code rings rotatable about an axis of rotation and a latch that is preloaded along the axis of rotation in the direction of a locked position. The lock body has an introduction opening through which the locking bar of the jointed bar hoop can be introduced into the lock body along an introduction direction that is oriented transversely to the axis of rotation of the code rings, with the locking bar introduced into the lock body being locked to the lock body when the latch is in the locked position and is blocked. The latch and/or the locking bar of the jointed bar hoop has/have at least one slope that is configured to effect an urging back of the preloaded latch from the locked position into a release position on a removal of the locking bar from the introduction opening of the lock body and/or on an introduction of the locking bar into the introduction opening of the lock body.

A lock assembly includes a box composed of two parts, and a room is defined between the two parts. Keys and key chains are stored in the room. A number wheel unit is connected to the box and includes multiple number wheels partially exposed beyond the box for convenience of operation. A shackle unit is connected to the box so as to lock or unlock the lock assembly. A light-emitting unit is located within the room and powered by a power source. The light-emitting unit illuminates the number wheels of the number wheel unit for convenience of operating the number wheels at night. The two parts can be opened to access the keys and the key chains by operating the number wheels correctly.
