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.

A code changing structure for a key coded lock, including a lock base, a push rod, locking pieces, a knob, a linkage assembly, a position resetting assembly, and corresponding key springs, password keys, button springs and buttons. A press-rotating mechanism operable below a code changing height is provided between the buttons and key slots. When a correct password is entered, the knob rotate to a first angle or a second angle. When the knob rotates to the first angle, the key coded lock is in an unlocked state, the lock pieces move away from the knob and prevent the buttons to reach the code changing height. When the knob rotates to the second angle, the lock pieces move towards the knob and allow the buttons to be pressed down to the code changing height so as to drive the password keys to rotate to change the password.

The present invention discloses a combination lock mechanism for a lock, it includes a plurality of dials and an elastic member, each dial has a plurality of blocks and a plurality of grooves, each block has an identification element respectively, each groove is located between two adjacent blocks, the elastic member is located beside the combination mechanism and having a basic sheet and plurality of elastic sheets, each elastic sheet is connected to a side of the basic sheet, and each elastic sheet has a protruding portion on both ends respectively, each protruding portion can be lodged into each groove of the dial.

An object padlock comprising, an object looking cover/body shape, at least one dial to control the opening of the lock as a primary control mechanism which is said to be a combination mode, a locking means such as a cable with one end always in the padlock and the other end such as a flexible-end can be locked and opened via a combination dial control, and at least a cylinder to control the opening of the lock as a secondary control mechanism which is said to be unlock by key mode.

An electronic storage cabinet lock includes a lock housing, a lock core, a circuit board, a motor assembly, a clutch mechanism and a battery assembly that are installed in an outer shell. A button assembly and a handle are mounted on the outer side of the outer shell. A cam is mounted on the motor assembly. One end of the lock core is secured in a shaft hole of the handle. When a password is correctly inputted, the button assembly transmits information to the circuit board to control the motor assembly to operate. The cam is driven to rotate to control the open state or closed state of the clutch mechanism. The handle can rotate to drive the lock core to rotate, thereby rotating a lock tongue to open the lock.

The disclosure relates to a lock structure. The combination lock mechanism includes multiple number wheels, multiple wheel cylinders, multiple wheel cylinder springs and a wheel rod. The wheel cylinder springs press between the wheel cylinders. The wheel cylinder has a plane portion and a round tab. The key lock mechanism has a lock seat and a lock core. The control sheet assembly has a lock core control sheet with multiple protrusive shafts, a support spring and multiple shaft wheels. The lock core control sheet touches the plane portion or the round tab. The support spring elastically presses the lock core control sheet. The lock core control sheet rotates about the protrusive shafts to engage with the lock seat when touching the round tab.

Disclosed in the present invention is a novel code wheel combination lock, comprising a knob and a face plate that can rotate with respect to each other, a lock tongue, and a code wheel assembly. The code wheel assembly comprises a base having an accommodation cavity, a code wheel shaft, several sets of bushings and code wheels, a reset mechanism, a positioning member, and a protection frame; the base is mounted on the face plate; the code wheel shaft passes through a movement cavity and can axially moves; the bushings are sleeved on the code wheel shaft and can rotate together with the code wheel shaft or with respect to the code wheel shaft; the code wheels are sleeved on the bushings and can rotate together with the bushings or with respect to the bushings; the reset mechanism is used for resetting the code wheels; the positioning member is used for limiting reset of the code wheels; the protection frame is used for changing the matching mode between the code wheels and the bushings; in the rotation of the knob and the face plate with respect to each other, there are a first position, a second position and a third position to respectively implement the functions of locking, automatic code wheel reset, and manual password setting. The present invention has a function of automatically resetting the code wheels after unlocking and before locking, thereby improving the product safety and preventing password exposure.

A zipper lock has two locking members to secure two zipper pulls of a suitcase and a control plate to cause the locking member to disengage from the zipper pulls. The lock has a latch engaged with the control plate, the latch positionable in a first latch position when the lock is in a locked mode or in a second latch position to open the lock. The lock has a combination mechanism using dials and clutches to control the movement of a spindle which allows the latch to move the second latch position when the arrangement of the dials matches the correct combination code. The lock also has a key-overriding mechanism using a cylinder to cause the movement of the latch when a correct key is used to turn the cylinder to open the lock. A recovery mechanism allows a user to recover the lost combination code.

A lockset comprises an upper shell and a bottom plate which are fixedly connected to each other. An accommodating space is formed between the upper shell and the bottom plate. A jack is provided on the surface of the upper shell. A locking mechanism is provided within the accommodating space. The locking mechanism comprises a locking hook fitted with the jack and a control device for controlling the locking hook to move. The locking hook comprises a hook portion accessible to the underneath of the jack and a connection portion controlled by the control device. When a code is correct, the hook portion may move toward one side of the jack; and, when the code is wrong, the connection portion is limited by the control device, and the hook portion is limited underneath the jack.

A locking device that can be mounted into a rotating or swinging door is disclosed. The locking device can have a deadbolt. The locking device can detect the position of the deadbolt and/or whether the door is closed. The locking device can have a camera, microphone and speaker. The locking device can send images detected by the camera and audio detected by the microphones to a remote computer.
