A latch assembly having a latch buckle and a latch tongue. The latch buckle includes: a buckle housing; a first lateral aperture disposed along a first side of the buckle housing; a second lateral aperture disposed along a second side of the buckle housing; a pair of h-shaped levers, each pivotally coupled to an interior of the buckle housing; a spring ring disposed between the pair of h-shaped levers; a pair of springs, each spring being coupled to an interior of the buckle housing and an h-shaped lever; and a buckle aperture disposed along a top of the buckle housing and between the pair of h-shaped levers. The latch tongue includes: a tongue plate; a plate spacer, coupled to the tongue plate; and a latch flange, coupled to the plate spacer, configured to be received by the buckle aperture. The latch tongue is selectably coupled to the latch base.

An adjustable buckle lock has a hook unit, a fixing unit, a wrench unit, an adjustment assembly, and a buckling ring unit. The hook unit can be securely mounted on a first locked object, and the fixing unit can be securely mounted on a second locked object. A pivotal end of the wrench unit is pivotally mounted on the fixing unit. The adjustment assembly is mounted on the wrench unit, and the buckling ring unit is pivotally mounted on the adjustment assembly and selectively hooks on the hook unit. With the moving of the buckling ring unit controlled by the adjustment assembly, the distance between the buckling ring unit and the hook unit is changed, and thus the pulling force for the buckling ring unit hooking on the buckling ring unit is adjusted, which ensures the first locked object and the second locked object are sealed together by a suitable force.

A hand bag having providing an open top has a zipper for closing the open top and has a tab for connecting to a fingerprint lock mounted on the hand bag.

The present invention is referred to as a theft prevention strap operable to secure one or more zipper sliders. In embodiments, the strap may include at least two strap ends and a tag end, wherein each strap end includes an opening. A first strap end may be passed underneath a handle of a piece of luggage, a second strap end may be passed over the top of the handle, and a padlock shackle may be passed through both openings and one or more openings associated with one or more zipper sliders. Thereby, the strap may be held in place by the handle, and the zipper sliders may be held in place along a corresponding zipper track such that the zipper sliders cannot be moved along the zipper track to cover up an attempted theft.

An opening and closing device is provided, including a fixing device and a limiting device. The fixing device includes a fixing portion and a fixing member, and the limiting device includes a driving device, a limiting portion, and a limiting member. The fixing member may rotate to be engaged with the fixing portion. The driving device is disposed on a first shell. The limiting portion is disposed on an inner side of the first shell. The limiting member is disposed on an inner side of a second shell. When the first shell approaches the second shell, the limiting member end portion may be engaged with the limiting portion. The driving device may be subjected to an external force to release the engagement between the fixing member and the fixing portion and the engagement between the limiting member end portion and the limiting portion.

The present application discloses a combination lock including a lock body and a lock hook controlled by the lock body so as to be locked into or separated from the lock body; the lock body includes a base, an upper cover connected to the base, and a latch mechanism and a control circuit board disposed in a cavity enclosed by the base and the upper cover, the control circuit board receives an external trigger signal and controls the latch mechanism to move, achieving locking into or separation from the lock hook. Compared with the prior art, a combination lock and a notebook using the same of the present application uses fingerprint or digital touch control to perform identification, and has the control circuit board to control the movement of the motor, which automatically drives the latch piece to unlock and lock the lock body and lock hook.

Locking device having first and second combined connection carriers for establishing a detachable connection. A rotation element is rotatably attached at the first connection carrier and is provided in an inner region thereof. The inner region is centered with respect to a center axis and has a full radius. Elastic blocking heads are attached at the first connection carrier at the inner region, and are movable from a blocking to a release position. The rotation element includes segments extending up to the full radius and segments extending at a maximum up to a smaller inner radius. The segments extending up to the full radius move blocking heads into the release position and the segments extending up to the inner radius leave blocking heads in the blocking position. Key tongues move bordering ones of the blocking heads into the release position and allow rotation of the rotation element.

Provided is a luggage lock including a zipper tab and a lock body. The lock body includes a housing, a lock hook mechanism and a drive mechanism. The housing is provided with at least one lock hole capable of being in fit with the zipper tab. The lock hook mechanism is disposed in the housing and includes a snap hook assembly, the snap hook assembly is movable between a locking position and an unlocking position, the locking position is aligned with one lock hole, and the unlocking position is located outside the one lock hole. The drive mechanism is disposed in the housing and is capable of driving the snap hook assembly to move between the locking position and the unlocking position.
