Technical Field
[0001] This application relates to the field of fire hydrant box technology, specifically a fire hydrant box. Background Technology
[0002] Fire hydrant boxes are important fire protection facilities inside buildings, used to store fire hydrants and other fire-fighting tools.
[0003] Most existing fire hydrant boxes use traditional door lock mechanisms. These locks usually require specific keys or tools to open, which to some extent ensures the safe storage of fire-fighting equipment and prevents unauthorized personnel from taking them. However, in sudden emergencies, these locks may become obstacles to accessing fire-fighting equipment. Secondly, the internal space of most fire hydrant boxes is fixed and cannot be reasonably adjusted according to the size of the fire extinguishers and tools stored. This means that in actual use, some larger fire extinguishers and tools may not be able to be put into the box smoothly, or even if they are put in, they may not be properly secured and protected.
