いた。However, in the case where the boss nut 22 is welded to the wall surface 21 and the light-shielding plate 23 is attached with the set screw 25, the set screw 2 is attached to the surface of the light-shielded plate 23.
Since the head of No. 5 is exposed, the appearance is poor, and there is a concern that the set screw 25 may be removed by mischief. further,
In order to mount the light shielding plate 23 at the installation site of the electric device storage box, the mounting hole 24 of the light shielding plate 23 must be aligned with the boss nut 22 and the set screw 25 is screwed. There was a problem. In addition, when the light-shielding plate 23 installed on the roof is to be provided with a draining slope, the light-shielding plate 23 attached to the other wall surface 21 has a different mounting member from that of the light-shielding plate 23. There has been a long-awaited need for a roof light-shielding plate that can be used in common with the light-shielding plate 23 for the wall surface and has a common mounting method.

FIG. 1 is a side view of an electric equipment storage box according to the present invention, wherein 1 is a main body of the electric equipment storage box, and 2 is a door thereof. Reference numeral 3 denotes a light-shielding plate provided outside the outer surfaces of the main body 1 and the door 2. Although the illustrated light shielding plate is installed on the outer surface of the door 2 among the outer surfaces, the same applies to the light shielding plates on the other outer surfaces. On the inner surface of the light shielding plate 3, a plurality of boss studs 4 each having a bolt shaft portion 4b planted at the center of the tip of the boss portion 4a are fusion-welded at the base end, that is, four boss studs 4 are mounted corresponding to the four corners of the outer surface. The bolt shaft portion 4b of the boss stud 4 is inserted into a mounting hole 5 penetrated through the outer surface of the box, a washer is interposed in the bolt shaft portion 4b, and a nut 6 is screwed into the light shielding plate 3. Is formed by forming a gap between the outer surface and the boss portion 4a of the boss stud 4. A waterproof packing 7 is fitted between the base end of the bolt shaft 4b and the outer surface. In addition. Reference numeral 3a denotes a bent portion formed inward on the peripheral surface of the light shielding plate 3 to prevent rainwater from being blown.

置される。The light-shielding plate 3 mounted on the roof surface 1a of the outer surface of the box may be mounted in the same manner as described above when it is not necessary to provide the roof surface 1a with a drainage slope. . However, if it is necessary to install the boss studs 4 with inclinations for draining with respect to the roof surface 1a, of the boss studs 4 attached near the four corners, the boss studs 4 in different rows in the front-rear direction or the left-right direction are used. Seat plates 8a and 8b having different heights are fitted to the base of the bolt shaft 4b, and the end of the bolt shaft 4b is inserted into a mounting hole 5 penetrated through the roof surface 1a of the box.

される虞の無いことにある。In the electric device storage box of the present invention thus constructed, the light shielding plate 3 is provided on the outer surface of the boss portion 4 of the boss stud 4.
a, a gap is formed and attached, so that radiant heat from the outside such as direct sunlight can be avoided, and of course, heating inside the box radiated from a window with louvers installed on the outer surface (not shown) It is the same as the conventional box for storing electric equipment that can release the discharged air and take in the outside air. However, a feature of the present invention is that the light shielding plate 3 has the bolt shaft portion 4b of the boss stud 4 whose base end is welded to its inner surface inserted into the mounting hole 5 penetrated through the outer surface of the box, and the nut 6 is screwed. Since they are attached together, the surface of the light-shielding plate 3 has a clean appearance, and since the mounting nut 6 is in the box, there is no risk of being removed by mischief.

Since the nut 6 is screwed from the inside of the upper surface, the bolt shaft portion 4b is temporarily held in the mounting hole 5, so that the nut 6 can be screwed into the bolt shaft portion 4b without particularly supporting the light shielding plate 3. This can be easily performed. Further, since the waterproof packing 7 is fitted to the base end of the bolt shaft 4b and the bolt shaft 4b is inserted into the mounting hole 5, the waterproof packing 7 does not fall off before the nut 6 is screwed. After the nut 6 is tightened, it is sandwiched between the peripheral surface of the mounting hole 5 and the tip of the boss 4a of the boss stud 4, and exhibits a sufficiently waterproof function.

る。When it is necessary to install the light-shielding plate 3 attached to the roof surface 1a of the outer surface of the box with a slope for draining the roof surface 1a, four bosses attached near four corners are required. Bolt shaft portions 4 of boss studs 4 in two different rows in the front-back direction or the left-right direction of studs 4
seats 8a and 8b having different heights are fitted to the base of the box b, and the tip of the bolt shaft 4b is inserted into a mounting hole 5 penetrated through the roof surface 1a of the box, and a nut 6 is inserted into the bolt shaft 4b. Is screwed and installed on the roof surface 1a with an inclination, so that it is only necessary to add the seat plates 8a and 8b which are easy to manufacture and can be provided at low cost, so that it can be provided at low cost. Moreover, since the seat plates 8a and 8b are made of rubber having a slope and a waterproof function, a separate waterproof packing is not required and the number of parts can be reduced. Therefore, it can be easily dealt with after judging whether or not the electric equipment storage box is to be inclined at the installation site.
