Description

Technical Field

[0001] The present invention relates to a luggage lock, and in particular to a zipper lock and a luggage case. Background Art

[0002] Currently, existing luggage locks offer both password unlocking and key unlocking, both of which can be used to unlock the lock. However, these existing locks have relatively complex internal structures, making them prone to malfunctions such as jamming, and are also relatively expensive to manufacture. Another drawback is that when the combination wheel is unlocked, the button's rigidity prevents the movable plate from moving. When the movable plate is immobilized, the combination wheel is prone to code skipping. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a zipper lock.

[0004] The objectives of the present invention are achieved through the following technical solution: a zipper lock comprising a housing, wherein a lock core assembly, a combination wheel assembly, a lock hook assembly, a movable piece, a button, and a code adjustment switch are disposed within the housing; the combination wheel assembly and the lock core assembly are both capable of controlling the movement of the movable piece; the button comprises a push knob and a movable block, the push knob and the movable block being movably connected, the push knob moving in a longitudinal direction, and the movable block moving in a transverse direction. When the combination wheel assembly is unlocked, the movable piece, having a movable piece spring, can move the movable block laterally by simply overcoming the elastic force of the movable block, thereby preventing the combination wheel assembly from jumping codes when unlocked.

[0005] In the locked state, the movable block presses against the movable plate, the button cannot be pushed vertically, and the code adjustment switch also presses against the movable plate, so code adjustment cannot be achieved. The code adjustment switch can only adjust the code of the code wheel when the code entered on the code wheel is correct.

[0006] As an improvement to the zipper lock of the present invention, a stop block is provided at one end of the movable piece corresponding to the button, and a movable block spring is provided on the movable block, and the stop block can limit the unlocking movement of the button;
