[0002] The disposable packaging in the traditional express delivery industry has some environmental issues, such as cartons, tapes, and label papers. They all contain non-degradable substances such as glue. At present, some express delivery companies have launched recyclable packaging boxes, but they cannot be taped or locked, which poses a safety hazard, and disposable label papers are still required. If they need to be locked, traditional zipper locks may be used. Usually, the slider is locked after the locker teeth are engaged to limit the movement of the slider to achieve the purpose of anti-theft.

[0003] The zipper locks currently on the market have a core structure of a combination lock mechanism that includes several combination disks, several combination disk limit blocks, combination disk springs, and combination disk shafts. The purpose of unlocking is mainly achieved by rotating the combination disk to release the restriction of the code disk limit block on the slider. The disadvantages are: the combination disk is easily affected by dust when rotating. Once dust enters the combination disk, it will be stuck and the luggage cannot be opened normally. In addition, there are too many passwords in modern life and it is easy to forget the password. Therefore, there is room for improvement. Summary of the invention

In other embodiments, the sensing terminal is an induction antenna.

[0043] The working principle of the present invention is as follows: when the user manually locks, the locking member 222 moves to the side close to the bottom of the movable groove a to the locking position. At this time, the lock hole d on the locking part 202 is restricted inside the zipper head. The rotor 232 is driven by the restoring force of the torsion spring 235 to separate the limiting member 234 from the accommodating groove f and push the limiting member 234 into the limiting groove e. The power source 231 drives the transmission member 233 to reverse, thereby making room for the torsion spring 235 to flip and avoid when unlocking. At this time, the zipper lock is in a locked state. When the user unlocks through the unlocker, the power source 231 drives the rotor 232 to rotate, so that the accommodating groove f on the rotor 232 rotates to the position where the limiting member 234 is located. At the same time, the elastic member 223 drives the driving block 221 to reset. The driving block 221 moves so that the limiting groove e on the locking member 222 is separated from the limiting member 234 and the limiting member 234 is pushed into the accommodating groove f. At this time, the lock hole d on the locking part 202 is separated from the zipper head.
