Description

Technical Field

[0001] The utility model relates to the technical field of luggage locks, and particularly relates to a double-button multi-layer luggage lock. Background Art

[0002] With the development of society, two-layer luggage can no longer meet the needs of some people, so multi-layer luggage with three or more layers has gradually emerged on the market. At present, for these multi-layer luggage, generally a password lock is installed between every two adjacent layers. That is to say, at least two independent password locks need to be installed for multi-layer luggage. For luggage merchants, the cost is high, and for users, it is not very convenient to use.

[0003] Subsequently, the Chinese patent document with the publication number of CN110230439A discloses a password lock for multi-layer luggage. The key technical points of its technical solution are that it includes a first limiting component and a second limiting component; after the password lock is locked, the first limiting component and the second limiting component respectively limit and lock different layers of the multi-layer luggage. Through the setting of the first limiting component and the second limiting component, it is realized that different layers of the multi-layer luggage can be limited and locked at the same time, and this password lock is an integral lock. Compared with the prior art that requires at least two sets of locks to be installed, the cost is lower and it is also more convenient to use. When the above prior art password lock is unlocked through the key component, the key component moves to release the locking of the three-layer luggage, and the password unlocking and key unlocking are used to unlock different layers of the luggage. Its structure is relatively complex and the manufacturing cost is relatively high.

[0004] Subsequently, there appears a simple multi-layer luggage lock disclosed in the Chinese patent document with the publication number of CN220790913U, which includes a front cover lock body and a main lock body. The front cover lock body includes a support shell, a sub-lock catch and a linkage rod. The sub-lock catch is movably installed in the support shell; the linkage rod is slidably installed in the support shell; the main lock body includes a lock shell, a key component, a main lock catch and a transmission rod. The main lock catch is movably installed in the lock shell; the transmission rod is slidably installed in the lock shell. The transmission rod is connected with an operating member extending out of the lock shell, and the operating member extends and connects the linkage rod; the key component includes a lock core and a strip-shaped unlocking block. The transmission rod is provided with a strip-shaped unlocking hole, and the length of the unlocking hole matches the length of the unlocking block. The unlocking block is located in the unlocking hole; in the locked state, both ends of the unlocking block abut against the inner wall of the unlocking hole to limit the sliding of the transmission rod; in the unlocked state, the unlocking block rotates with the lock core to release the limit on the transmission rod. The structure of the key component is simple, reducing the manufacturing cost.

[0005] The above-mentioned unlocking by the operating member that slides left and right requires the user to apply a certain lateral thrust to drive the operating member; moreover, the above prior art only has the functions of locking and unlocking, and the functions are slightly single.

[0006] In addition, the secondary lock catch of the front cover lock body is rotatably installed, occupying a large space, making the support shell large in volume, affecting the aesthetics and requiring a large installation space to be reserved in the luggage. Summary of the Invention
