Description

A kind of thin luggage combination lock

technical field

The invention relates to the technical field of locks, in particular to a thin combination lock for luggage suitable for being installed in a shallow recess of a box body.

Background technique

For the convenience and safety of traveling, luggage coded locks are generally provided on luggage, and luggage coded locks generally use digital codes or keys to control the movement of the inner lock of the coded lock, so that the lock buckle and the lock hook on the luggage are buckled or disengaged. , so as to realize the locking or unlocking of the luggage, the password lock of the luggage is easy to operate, safe and reliable, and has a wide range of applications.

Since the combination lock is a precision part, it is easy to be damaged, and it is difficult to repair after damage, thereby reducing the safety performance of the bag. Therefore, the bag is generally provided with a recessed part, and the combination lock is set in the recessed part. During the use of the bag, The concave part provides certain protection for the combination lock inside, thereby improving the service life of the combination lock. Because the thickness of the existing combination lock is relatively thick, when the combination lock is installed in the recessed part of the box body, the recessed part must have sufficient depth, so that the combination lock can be completely hidden in the concave part, and then the effective However, if the depth of the concave part is designed to be deep, it will inevitably occupy the space in the bag, thereby reducing the storage space in the bag, and will also weaken the structural strength of the concave part, thereby weakening the structural strength of the entire bag. To solve the above problems, it is necessary to design the recessed part of the case and bag shallower, which brings another problem. When the existing coded lock is installed in the shallow recessed part, the recessed part cannot completely hide the coded lock, that is, the coded lock. A part is exposed in the recessed part, so that the shallower recessed part cannot protect the function of the combination lock, and the existing combination lock generally realizes the automatic unlocking of the combination lock by pressing the pushed side part, and the shallower recess The part reduces the contact area between the push system and the fingers, which is very inconvenient to operate the push system.

Therefore, it is necessary to improve the structure of the existing combination lock to make the overall thickness of the combination lock thinner, so that the combination lock can be installed in a shallower recessed portion, and provide certain security for the combination lock.
