A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

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.

A method of an optical sensor apparatus which is to be used with a controlling device arranged for controlling an object having a long shape and flexible form of a material, includes: using a light emitting circuit to generate and output a light ray to a surface of a portion of the object; sensing the light ray reflected from the surface for multiple times to generate multiple images; detecting at least one motion image in the generated multiple images; and, determining a motion, an offset, or a rotation angle of the object, which is controlled by the thread controlling device, according to the detected at least one motion image.

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 dial ring assembly for an electromechanical combination lock includes a housing configured to be mounted on an exterior of a securable enclosure, a dial rotatably disposed on the housing, the dial being rotatable about a dial axis for use in connection with entry of a combination, a lever rotatably disposed on the housing, the lever being rotatable about a lever axis, an external generator disposed in the housing, the external generator being configured to generate electrical energy through rotation of an external generator shaft of the external generator, and a gear train disposed in the housing and operatively connecting the dial, the lever, and the external generator shaft such that rotation of the dial rotates the external generator shaft to produce electrical energy and rotation of the lever rotates the external generator shaft to produce electrical energy.

A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

A locking module includes: a storage unit in which a password is saved; an input unit which receives a number as an input; a locking unit which restrains a zipper and thereby restricts the sliding of the zipper in a state in which two housings are coupled through the zipper; and a control unit which, when the saved password matches the input number, transmits a lock release signal to the locking unit and controls to release the zipper restrained by the locking unit.
