[0002] In the field of modern communications, walkie-talkies, as an important communication device, are widely used in various industries. However, how to effectively manage and charge these walkie-talkies has become an urgent problem to be solved. In order to solve this problem, the walkie-talkie centralized charging box came into being. The walkie-talkie centralized charging box is a charging device specially designed for walkie-talkies. It has the following significant features. First, centralized charging. It can charge multiple walkie-talkies at the same time, greatly improving the efficiency and convenience of charging. Second, it is safe and reliable. It has multiple safety protection mechanisms such as overcharge protection and short circuit protection to ensure the charging safety of walkie-talkies. Third, it is easy to manage. Multiple walkie-talkies can be managed uniformly, which is convenient and fast. Fourth, it saves space. Placing multiple walkie-talkies in one charging box effectively saves space. In short, the walkie-talkie centralized charging box plays an important role in improving work efficiency and ensuring communication security, and is an ideal choice for various enterprises and institutions.

[0003] For example, the Chinese patent with publication number CN211239376U discloses a centralized charging box for walkie-talkies, including a charging box and a power supply box; there are multiple charging boxes, and the multiple charging boxes are combined into a rectangular arrangement; the charging box includes: a box body; a box door is hinged on the front surface of the box body, a walkie-talkie charging seat is provided at the bottom of the inner surface of the box body, a lighting lamp is provided at the top of the inner surface of the box body, a contact switch is provided at the position where the front end of the bottom of the inner surface of the box body contacts and overlaps with the box door, and a current indicator light is provided at the bottom of the front surface of the box body.
