Description

Technical Field

[0001] The utility model relates to the technical field of key-press password locks, in particular to a battery compartment structure of a key-press password lock. Background Art

[0002] Electronic key combination locks are usually unlocked by the user inputting a password. When the password is correct, the motor is given an unlocking command to unlock the lock. Currently, the electronic key combination locks on the market are getting smaller and smaller, and the structure is relatively simple. Generally, they are not powered by power cords, but have built-in pop-up battery compartments, which are powered by button batteries.

[0003] The current battery compartment structure has safety hazards: the existing battery compartment generally uses a snap switch to assemble with the lock shell. The user can insert the battery compartment into the lock shell to lock the snap switch. When the battery compartment is pressed again, the snap switch is unlocked and the battery compartment pops out. Similar structures do not have any opening restrictions, and children can easily take out the battery compartment, which may cause the battery to be swallowed by mistake. Utility Model Content
