Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a compact lift-type luggage lock. Background Technology

[0002] A bag lock is a type of lock accessory installed on bags. Its function is to lock closed bags to prevent them from being accidentally opened or stolen.

[0003] The bag has a frame on both sides of the opening. The outer side of the frame is rounded and raised. The frame can increase the strength of the edge of the bag opening and facilitate the installation of the bag lock. The bag lock currently used includes a first mounting base, a second mounting base, and a lock plate. One end of the lock plate is hinged to the first mounting base, and the other end of the lock plate is the locking end. The second mounting base is provided with a locking structure for locking the locking end of the lock plate.

[0004] The existing technology has a hinged structure at the end of the lock plate that is not compact enough. It relies on the lock plate's hook to be inserted into the lock hole for locking. In the event of a collision or heavy drop of the bag, the lock hook is prone to breakage, which affects safety.

[0005] The inventor has developed a lifting-type bag lock, Chinese patent application number 202422985533.1, which is not yet publicly disclosed. The lock comprises a lock housing, a locking mechanism, an unlocking component, a lock plate, and a swing block. The lower end of the swing block is hinged to the lock housing, and the upper end is hinged to the middle of the lock plate. The front end of the lock plate has a hook portion. When unlocking, the lock plate swings forward about the swing block as a pivot to lift relative to the lock housing. When locking, the lock plate swings backward about the swing block as a pivot and rests downward against the lock housing. The locking mechanism holds the lock plate in place. After the correct command is input into the locking mechanism, external force can release the lock plate. In use, the lock housing is fixed to one side of the bag's opening / closing side, and the hook portion of the lock plate is used to hook onto the other side of the bag's opening / closing side to achieve locking. When the lock plate moves downwards towards the lock case from its raised position, it can move backwards with the swing block as the pivot. Therefore, it can hook the two sides of the bag close together, making the two sides of the bag fit together more tightly and making it less likely to be maliciously unlocked.

[0006] However, some consumers are not used to manipulating the horizontally arranged combination wheels at the end of the lock case, so this type of luggage lock needs further improvement. Summary of the Invention

[0007] In view of the above-mentioned technical problems, the present invention provides a compact lifting-type luggage lock.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

The cipher wheels are longitudinally positioned and partially protrude from the top of the assembly table. The multiple code adjustment wheels are coaxially installed inside the cipher wheels, and the code adjustment wheels rotate together with their corresponding cipher wheels. The central rod passes through the multiple code adjustment wheels, and the central rod can only move axially after the multiple cipher wheels have rotated to the correct cipher.

[0015] The arched section is equipped with a lock core and a strip-shaped lock block. The bottom of the lock core is equipped with a linkage protrusion, and the lock block has a strip-shaped hole. The linkage protrusion is inserted into the strip-shaped hole so that the lock core and the lock block can rotate together, while the lock block can slide relative to the lock core.

[0016] In the locked state, the locking blocks press against the center rod and the push knob respectively;

[0017] When unlocking with a combination, after the combination wheel turns to the correct combination, the push knob, lock block, and center rod move together to unlock;
