Background

Fire boxes are a requisite safety device for modern buildings. In order to meet the indoor decoration effect, holes are reserved in indoor walls at present for installing fire-fighting boxes and storing fire-fighting water pipes, fire-fighting tools and other objects, and meanwhile, transparent door bodies capable of being opened are connected on door frames with the holes through hinges. Once a fire disaster occurs, people can manually open the transparent door body to take out and use the fire-fighting water pipe, the fire-fighting appliance and other articles in the transparent door body.

At present, in building decoration construction, in order to increase the appearance of a building, people usually install a frame outside an indoor wall body through a reinforcing keel, and fix a decoration plate (such as stone, wall bricks, wood repair surfaces and the like) through the reinforcing keel. The fire-fighting box is characterized in that an openable decoration door is arranged on the outer side of the fire-fighting box, and in order to facilitate opening of the decoration door, the decoration door is generally directly connected to a reinforcing keel on the outer side of the fire-fighting box by a hinge, and the opening angle of the decoration door can only reach 90 degrees although the decoration door can be opened.

According to the national standard 'fire-extinguishing box GB 14561-2003', 5.13-3: the opening angle of the fire extinguishing box door is not smaller than 160 degrees, and the box door is light and flexible to open and close, and has no blocking phenomenon. The opening tension is not greater than 50N.
