A lock is provided, the lock having: a lock mechanism having a first member and a second member, the first member and the second member each being slidably mounted to a housing of the combination lock, wherein the first member is capable of movement between a first position and a second position and the second member is capable of movement between a first position and a second position and wherein movement of the first member from the first position to the second position causes the second member to move from the first position to the second position; a bolt configured for movement between a locking position and an unlocking position, the bolt preventing the second member from moving from the second position to the first position when the bolt is in the locking position.

An electronic combination lock has a touch panel for combination code entry. If the combination code matches a preset code, a solenoid in energized to unlock the lock, allowing a user to pull up the shackle to open the lock. The user can be a master user, a regular user or a temporary user with each type of users having different level of access. For example, the master user can have unlimited number of times to use the master combination code, while a temporary user has only a limited number of times to use its temporary code as designated by the master user. In one embodiment, the lock can be opened with a key. In another embodiment, the user can enter the combination code from a detached electronic device.

A thin padlock with simple and convenient operation includes a lock hook, a lock buckle and a lock cylinder module capable of locking the padlock. The lock cylinder module is embedded into a box; a small portion of the lock cylinder module is protruded from the outer surface of the box, so that the thickness of the padlock protruding to the outside of the box is reduced, and the padlock will not be damage by external forces easily. In an unlock process, the lock cylinder module slides with respect to the box and drives the lock hook to move and be separated from the lock buckle. The lock cylinder module integrates a pressing unlock function to skip the pressing action, thus not just reducing the thickness of the padlock protruding to the outside of the box only, but also allowing users to operate the lock cylinder module by a finger to unlock the padlock and improve the convenience of operating the padlock.

A combination lock can be operated manually via the manipulation of rotatable dials and by way of a key, such as an electronic key. The lock includes one or more rotatable dials each having multiple indicia disposed thereon. Rotation of the rotatable dials to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a latched position and a second position in which the lock is in an unlatched position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.

A dual-code lock core is provided, including a first unlocking component, a code wheel, and a second unlocking component. When the code wheel rotates to a first unlocking position, the first unlocking component may move to unlock the dual-code lock core; and when the code wheel rotates to a second unlocking position, the second unlocking component may move to unlock the dual-code lock core.

A lock includes a housing having a plurality of apertures receiving buttons. A biasing member biases each button towards an un-pressed position. A plurality of spools includes circumferential grooves. Each circumferential groove has a notch that is angularly displaced relative to each of the other notches on that spool. A plurality of legs is in communication with one of the buttons and contacts one of the circumferential grooves. A locking plate includes apertures receiving the spools. An actuator is associated with the locking plate and a latch. Pressing and releasing the buttons causes translation of the spool rotationally orienting a notch to be adjacent to the locking plate. The locking plate only moves into an unlocked position, when driven by the actuator disengaging the latch and unlocking the lock if all of the notches which are adjacent to the locking plate are in a unlocked rotational orientation.

The invention refers to a bolt to pin lock with interchangeable combination to be used mainly in gates, cold storage rooms, commercial vehicles, containers, wagons manufacturing facilities, and doors.

Disclosed is a combination lock, comprising a rotatable knob capable of relative rotation, a panel, a bolt, and a dial assembly. The dial assembly comprises a base having a movement chamber, a dial shaft, multiple sets of bushings and dials, a position resetting mechanism, a positioning member, and a protection frame The rotatable knob can be rotated relative to the panel to a first position, second position, third position, or fourth position, so as to achieve locking, automatic password resetting, automatic dial position resetting, and manual password setting. The combination lock uses one-time temporary passwords, thereby achieving superior security performance.
