Abstract: A multiple-latch-locking lock structure includes a casing in which a lock tongue control unit and a lock latch control unit are arranged. The lock tongue control unit includes an operation-linking member, a positioning member, an arresting member, a swinging member, and a slide block. When a lock core is rotated, the rectangular lock tongue and the triangular lock tongue are driven to get pushed out and retracted back for latch-locking and unlocking. The lock latch control unit includes a rotating member, a slide plate, and a slide bar. When a handle is rotated, the lock latch is driven to get pushed out and retracted back, thereby achieving security latch-locking and the slide plate is caused to move up and down to achieve a function of controlling a vertical latch. As such, multiple latch locking can be achieved to provide the lock with better security and better burglary resistance.

Abstract: The anti-theft device is configured in a door lock, and contains a first blocking piece, a second blocking device, a positioning piece, and a lever. The first blocking piece contains a first section and a second section bended and extended perpendicularly from the first section. The first section has a first through hole and a second through hole. The lever is engaged by a lock heart of the door lock. When the door lock is locked, the lock heart is turned to engage the lever so that the lever drives the first blocking piece downward by its first through hole. The second section of the first blocking piece as such blocks a lock tongue of the door lock so that the door lock cannot be opened without using key.

Abstract: A lock structure suitable for various lock cores includes an engagement arranged at one side of a lock core axle of a lock device. The engagement member includes a rod section such that the engagement member is coupled to a link bar. A handle axle includes an arrestor member, such that the arrestor member is coupled to a stop plate and a push bar. A retention member is arranged under the push bar. When the lock core axle is rotated by means of a key, the engagement member and the link bar are driven to achieve locking, or a handle is operated to achieve unlocking. When the lock core is damaged, the damaged lock core is replaceable with one of various types of lock core without the need to replace the entire lock thereby improving the utilization of the lock.

Abstract: A structure of lock includes a core shaft, a swing arm, a push bar, and a keeper plate that are arranged in a lock. The swing arm is arranged at one side of the core shaft to selectively push or separate from a bolt. The push bar is arranged on an axle and has a top edge forming a notch. The keeper plate includes an elongate slide hole formed therein and an elongate positioning hole also formed therein and located below the slide hole. The slide hole is slidably fit over the axle and the positioning hole is slidably fit over a bar in such a way that the keeper plate is movable up and down along a curved path.

Abstract: A lockset assembly with selective opening and closing, which primarily includes a press component, a linking component, a positioning component, a braking component, a sliding component, a connecting rod, a sliding rod, and an arresting rod. The press component is connected to the arresting rod using the linking component and the positioning component. The braking component is installed on one side of a handle shaft of the lockset, and the sliding component is installed on an upper edge of the handle shaft. The sliding component is able to slide along the handle shaft. Accordingly, pressing of the press component causes switching, which causes a displacement of the positioning component and a corresponding arrestment or disengagement of the arresting rod, thereby enabling the lockset to form a state which can be opened with a handle both from inside and outside a room.
