As an example of the disaster prevention equipment storage box, there is a device disclosed in Japanese Utility Model Publication No. 58-28389. In this invention, mounting screws are provided upright on the upper and lower opening edges of the box body, and a daruma hole having a small axis at the top is provided at the upper and lower peripheral edges of the storage frame (plate) to form a dull hole in the box. A large hole of a daruma hole is fitted into a vertically installed mounting screw, and the storage frame is lowered by its own weight so that the small hole is engaged with the mounting screw. Further, a support member is attached to one end of the upper and lower peripheral edges of the storage frame so as to project outward from the peripheral edge, and the opening / closing door is rotatably attached to the support member.

[0006] In Japanese Utility Model Application Laid-Open Nos. 53-92627, 54-631 and 56-164398, a terminal block is provided at the opening of the box embedded in the wall surface. An indicator frame, a transmitter, a bell and a plate door with a bell sound hole are installed by a hinge so that it can be opened and closed with screws, and the lead wires in the box and external wiring are attached to the terminal block with terminal screws. A general board and a fire alarm adapted to be connected are disclosed.

Further, in Japanese Utility Model Publication No. 2-37102, an indicator lamp, a bell, and a transmitter are installed in a front opening of a main body which has a terminal block to which internal and external wirings are connected by screws and which is mounted on a wall surface. A fire alarm system is shown in which fixed plates are fixed with screws.

[0008]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
According to the invention disclosed in Japanese Patent Publication No. 9, a large hole of a round hole provided in a storage frame (plate) is simultaneously fitted to four mounting screws erected on the box body, and the storage frame is lowered by its own weight to be small. Since the holes are engaged with each other, when mounting the storage frame, it is very troublesome to align the mounting screw with the daruma hole, resulting in poor work efficiency. When mounting the opening / closing door on the storage frame, a supporting member protruding outward is attached to one end of the upper and lower peripheral edges of the storage frame by welding, and the opening / closing door is mounted on the shaft mounted between the supporting members. The mounting work of the support member is not only troublesome, but also an obstacle.

Next, in the invention disclosed in Japanese Utility Model Laid-Open No. 53-92627, the plate door is attached to the mounting frame by a hinge, so that when the plate door is opened, the load of the entire plate door is hinged. Since the hinge may be deformed, and when the plate door is closed, the hinge may protrude into the box and come into contact with the wiring inside the box, the box must be made larger and stored. This hinders the miniaturization of boxes.

Further, since the terminal block is attached to the storage frame, the lead wire of the device attached to the plate door can be connected to the terminal block in advance, but it is arranged in the wall of the building and embedded in the wall surface. The external wiring taken in the box can be connected to the terminal block only when the storage frame is attached to the box or after it is attached.Therefore, it is extremely troublesome to perform these wiring work when there is not enough time. Yes, incorrect wiring is likely to occur. Further, since the mounting frame is fixed to the box with screws, the positioning and attachment / detachment of the holes are troublesome.

In the invention disclosed in Japanese Utility Model Publication No. 2-37102, the terminal block is attached to the main body, but since the plate is fixed with screws, it is troublesome to attach and detach the plate. This is also troublesome because the wiring is attached to the terminal block with screws.

In addition to the above-mentioned prior art, various devices have been proposed in which the plate is opened and closed by a hinge, but in many cases the opening angle of the door is small due to the function of the hinge (usually about 90 ° to 110 °). ) Therefore, when performing a wiring work or a maintenance inspection in the storage box, the door may hit the arm because the work opening area is small, which causes a problem in workability.

Although the box is generally installed in the vertical direction, it is often buried upside down in the wall surface. The box has directionality in relation to the plate attached to it, so if it is installed upside down, you will have to re-install the box, but it is extremely difficult to remove the box embedded in the wall and replace it. It is troublesome. Furthermore, as mentioned above, in order to prevent damage to the plate, only the box is embedded in the wall surface, and the plate is attached at a very busy and short time just before the completion of the building. At such times, the work of connecting the internal and external wiring must be performed, and a test must be performed to check whether the external wiring connected to the terminal block is properly connected to the fire receiver. Since these operations must be performed in an extremely short time, it is difficult for the above-mentioned conventional storage box to satisfy such a request for the above-mentioned reason.

The present invention has been made in order to solve the above problems, and provides a disaster prevention equipment storage box having no directionality in the box, easy plate attachment, and excellent workability in construction such as wiring. This is the purpose.

FIG. 13 shows another embodiment of the present invention. In this embodiment, a plurality of differential type distributed sensors and the like are attached to the box 1, so that the storage box has a large size. . With this configuration, the bell mounting portion 36 is formed in a substantially concave shape, and the arm portions 36b provided on both sides of the concave portion 36a,
A space portion A is formed between 36b and the bottom plate 2 of the box 1, and external wiring or internal wiring is passed through this space portion A.

As described above, according to the present invention, even if the box is accidentally embedded in the wall upside down, the box is constructed symmetrically in the vertical and horizontal directions. Therefore, the box can be directly attached without removing the box and replacing it. Can be installed. In this case, when the terminal block is mounted above the box, the terminal block may be removed and replaced with the lower embossing (in the past, the terminal block was generally fixed to the plate or the box by welding).

Also, since the terminal block is provided in the box, the external wiring provided in the wall can be pulled into the box and connected to the terminal metal fittings of the terminal block in advance, so that a short circuit test is also performed. Therefore, it is possible to confirm with a margin whether or not the fire receivers and signal lines are properly connected. In this case, the external wiring installed inside the wall may be pulled during the construction of the building, but as described above, the external wiring is fixed to the terminal bracket of the terminal block with terminal screws, so it will come off from the terminal block. There is no fear.

Insertion terminals are provided on each lead wire of the disaster prevention equipment provided on the plate, and when the plate is mounted on the box, these insertion terminals are connected by inserting into the insertion parts of the terminal fittings of the terminal block provided on the box. I decided to do so,
Even when there is not enough time, the wiring work can be performed easily and promptly. In addition, the terminal block can be easily removed and installed even in the event of maintenance or failure of the disaster prevention device. In this case, one end of the terminal metal fitting of the terminal block is bent diagonally upward to form the insertion part, so the insertion and removal of the insertion terminal can be performed easily and securely, and external wiring is screwed to the terminal part. In doing so, it is possible to prevent the external wiring from being inserted too much.

Further, since the inserting portion of the terminal fitting is bent obliquely upward, there is no possibility that the hand hits the bell mounting plate or the like at the time of connection. Therefore, the wiring work is facilitated, and the length of the terminal block protruding from the terminal block in the horizontal direction and the height direction can be shortened, so that the miniaturization of the storage box can be promoted.

Since notches are provided in one of the upper and lower inner peripheral edge portions and the left and right inner peripheral edge portions of the plate, it is possible to easily fit the screws that are erected in the screw holes of the vertically or horizontally long box on the wall surface. , The box can be fixed, and the box can be mounted vertically or horizontally. Further, since the partition wall is provided at the mounting portion of the bell facing the terminal block side, there is no fear that the wiring in the box will come into contact with the bell, and the bell can ring reliably when it rings.

Since the door is attached to the plate by the screw shaft, it can be opened until the surface of the door hits the outer peripheral wall of the plate. Therefore, the door is wider than before (130 °
Since it can be opened approximately, the work of connecting the lead wire to the terminal block and the maintenance work become easy. Also, when the door is opened, it is supported by the outer peripheral wall of the plate as described above,
No load is applied to the screw shaft. Furthermore, since the receiving member and the screw shaft do not project into the storage box when the door is closed, it is easy to downsize the storage box.

As shown in the embodiment of FIG. 13, if a space is provided between the arm portion of the bell mounting plate and the bottom plate of the box and the internal and external wiring is passed through this space portion, the wiring touches the bell. There is no fear, and the wiring can be surely processed.

[0044]

As is apparent from the above description, according to the present invention, the following effects can be obtained. (1) The bell is attached to the bell attaching portion having the partition wall, and the door having the indicator lamp, the transmitter, etc. is attached so as to be openable and closable in the box in which the terminal block is detachably attached and the box is formed vertically and horizontally symmetrically. Since the plate is detachably attached, even if the box is installed upside down, the plate can be attached as it is without changing the box. In addition, external wiring provided in the wall can be pulled into the box and connected to the terminal block in advance, and a short-circuit test can also be performed first, so the work process when there is no time to spare. Can be reduced. Further, the plate can be mounted in a short time and the wiring can be surely performed.
