The present invention is a lock system that can be used in the entire sector of white appliances and characterized by comprising a lock bolt (4) that fits into its seat through the stretching of the lock bolt housing (6) by means of the spring (3) located on the body (1) and a mechanism that allows the machine hatch to be closed by restoring the lock bolt housing (2) back to its former position even if the lock bolt housing (2) is in closed position.

The electronic actuator of an electronic padlock according to the invention is arranged to turn the cam piece (5) to release the latch parts (7) from a locking state and to turn the cam piece (5) to hold the latch parts (7) in the locking state. The cam piece (5) comprises a cover part (5A) and a shaft part (5B). The cover part has a central hole (12) for the shaft part. The shaft part (5B) has a shaft pin (15), which is set into the central hole (12). The shaft part also has a connecting part 19, which is arranged to be in contact with the electronic actuator 4. The cam piece further comprises a spring (9) which is between the shaft pin (15) and the cover part (5A). The spring comprises a first end (9A) and a second end (9B). The first end 9A is arranged to be in contact with the cover part 5A. The second end 9B is arranged to be in contact with the shaft part 5B. The spring is arranged to transmit turning force of the electronic actuator from the shaft pin 15 to the cover part 5A in the direction of said locking state.

A door lock system that adjusts to doors of different thicknesses. The door lock system may include self-adjusting spindles that engage and center a lock body in a door. The spindles may exert equal and opposing forces that center the lock body within the door and align the lock body with a latch.

A handle-locking mechanism for a door comprises a sliding bar, a locking member and a rotatable member all inside a lock body, wherein the rotary motion of the rotatable member drives an upper latch and a lower latch to a locking position and unlocking position; the sliding bar is slidably arranged inside the lock body and one end of the sliding bar abuts against the bolt, and the sliding bar is provided with a first elastic element, and the sliding bar is pushed against the elastic force from the first elastic element when the bolt retracts; the locking member is coupled with the sliding bar, and when the bolt stretches out, the locking member is brought by the sliding bar to a position to block the rotary motion of the rotatable member.

A latch structure according to an embodiment includes a body, a locking body, a latch head, a plunger, and a latch stopper. The body is disposed inside a door. The locking body moves in response to an external operation. The latch head protrudes from the body to maintain the door in a closed position, and rotates when the locking body is spaced apart at least a predetermined distance. The plunger retracts into the body to prevent the latch head from rotating while the door is being closed. The latch stopper prevents the protruding latch head from retracting into the body when the plunger is maintained within the body.

A motor vehicle door lock which is equipped with a locking mechanism substantially comprising a catch and pawl. Furthermore, a locking pin is provided for interaction with the locking mechanism. Furthermore, there is a damping element for a locking mechanism component and/or the locking pin. Finally, the configuration includes at least one spring which is assigned to the locking mechanism. According to the invention, the spring at least partially abuts the damping element.

An illustrative motor drive assembly is configured for use in a lockset comprising a case, a longitudinally movable link, and a catch configured to move among a locking position and an unlocking position in response to longitudinal movement of the link. The illustrative motor drive assembly includes a longitudinally extending shaft comprising a worm, a motor operable to rotate the shaft, a driver engaged with the worm, and a longitudinally extending spring. The spring is not directly engaged with the worm, and includes a first end coupled with the driver and a second end connectable with the link. Engagement between the worm and driver is configured to longitudinally move the driver in response to rotation of the shaft.

An anti-unlocked mechanism comprises a transmission gear, a sliding rod, a locking member and a first elastic member. The transmission gear includes an arc surface. An end of the sliding rod contacts the deadbolt of the lock body. The sliding rod is provided with a fixed stopper and a second elastic member. When the deadbolt is retracted, the sliding rod moves with the deadbolt against the elastic force of the second elastic member. When the deadbolt extends, the locking member moves with the sliding rod to block the rotation of the rotating part. The first elastic member comprises first and second protrusions. The second protrusion will not hinder the fixed stopper of the slide rod unless the first protrusion contacts with the circular arc surface, which will block the movement of the locking member to block rotation of the rotating part.
