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 securing device is provided. The securing device includes a body, a cover, a lock core, and a fastener. The cover is pivotally connected to the body. The cover is capable of rotating to a closed position or an open position with respect to the body. The lock core is disposed in the body or on the cover. When the lock core is in a locked state, at least a portion of the fastener is capable of inserting into the body from a side of the body, and the lock core restricts the fastener from leaving the body.

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.

An example lock apparatus includes a shackle including an engagement portion, and a lock head operable to selectively engage the engagement portion to thereby retain the lock apparatus in a closed condition. The lock head includes a housing, a slider, and a detent mechanism. The slider is mounted for sliding movement relative to the housing between a first position and a second position. One of the first position or the second position is a closed position in which the slider prevents removal of the engagement portion from the lock head, and the other of the first position or the second position is an open position in which the slider permits removal of the engagement portion from the lock head. The detent mechanism is configured to selectively resist movement of the slider from the first position.

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 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.

A lock has improved protection against lock picking. The lock comprises plural tumblers, each generally cylindrical in form with outer and inner circumferential edges, all the tumbles arranged on a common axis. The outer circumferential edge of each tumbler having a single true gate, including a void extending a predetermined distance toward the axis and plural false gates, each having a void of lesser extent. Ridges separates the true gate from adjacent false gates, and separate adjacent false gated from each other. The lock also includes a sheath contacting the inner circumferential edges of the tumblers. The sheath includes ridges located to maintain the tumblers in contact with each other.
