Alternatively, a storage box is configured by a box having a back surface attached to a wall surface and a plate that has an openable and closable door and is detachably attached to an opening of the box. In addition, a disaster prevention device such as a transmitter is attached, and the lead wires of these disaster prevention devices are connected to external wiring via a terminal block provided in a storage box and communicate with other devices.

When a box is to be embedded in a wall, the box is mounted on a frame provided on the wall and fixed with screws, and concrete is cast around the box and installed. At the stage of installing this box, only the box is installed because the building where the storage box is installed is performing interior work,
Plates are not installed to prevent them from getting dirty or damaged. When the interior work is completed, the plate is installed in a very short time, and the internal and external wiring connections and various tests are performed.

When a fire is found, a push button provided on the transmitter is pressed to send a fire signal to a fire receiver via external wiring and to sound a bell.
The indicator light is provided to indicate the presence of the transmitter. In such a disaster prevention equipment storage box, in addition to the above disaster prevention equipment, such as a repeater of a differential distributed sensor and a fire detector,

Problems to be Solved by the Invention
The device disclosed in Japanese Patent Application Publication No. 9-29139 proposes that the large holes of the round holes provided in the storage frame (plate) are simultaneously fitted to four mounting screws erected on the box body, and the storage frame is lowered by its own weight to reduce the size. Since the holes are engaged with each other, the positioning of the mounting screw and the Daruma hole is extremely troublesome when mounting the storage frame, and the working efficiency is poor. Also, when attaching the door to the storage frame, a support member protruding outward is attached to one end of the upper and lower peripheral edges of the storage frame by welding, and the door is axially fixed between these support members. Not only is the mounting work of the members troublesome, but also an obstacle.

Next, in the device disclosed in Japanese Utility Model Laid-Open No. 53-92627, since the plate door is attached to the mounting frame by a hinge, when the plate door is opened, the load on the entire plate door is reduced. Hinges may deform, and when the plate door is closed, the hinges may protrude into the box and come into contact with the wiring inside the box. This prevents the box from being downsized. Further, since the mounting frame is fixed to the box with screws, positioning of the holes and attachment / detachment are troublesome.

In the device disclosed in Japanese Utility Model Publication No. 2-37102, the terminal block is attached to the main body. However, since the plate is fixed with screws, the attachment and detachment are troublesome. This wiring is also troublesome because it is attached to the terminal block with screws.

In addition to the above-mentioned prior arts, various proposals have been proposed in which the plate is opened and closed by a hinge. However, in many cases, the opening angle of the door is small due to the function of the hinge (usually about 90 ° to 110 °). For this reason, when performing wiring work, maintenance, and the like in the storage box, the door may hit the arm due to the small work opening area, and there was a problem in workability.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a storage box for disaster prevention equipment which is easy to attach a door and detach a plate and has excellent workability in connection and the like. It is.
