Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box for housing electric equipment, in which parts can be attached to the inner surface of a box body or a cover.

[0002]

2. Description of the Related Art A conventional electrical equipment storage box of this kind is shown in FIG.
As shown in FIG. 3, a component 32 such as a locking metal fitting for locking a locking rod (not shown) is attached to the box body 31 on the inner surface of the box body 31 and is attached to the screw metal fitting 33 attached to the outside from the inside. It is usual that the screw member 34 is tightened and fixed.

[0003]

Therefore, in such a conventional one, the appearance is bad because the screw fitting 33 or the screw member 34 for attaching the component 32 is always exposed to the outside, and moreover, the appearance is bad. , Box body 31 cover 3
Even if 5 is capped and locked, it is possible to easily remove the component 32 from the outside by using a tool such as a screwdriver, which not only adversely affects the electric devices housed inside but also the component 32. In the case where is a locking metal fitting for locking the locking rod, there is a possibility that the cover 35 may be opened and mischief may occur and there is a problem in security.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in an electric equipment storage box for mounting parts on the inner surface of a box body or a cover,
A tightening member is formed by forming a pocket part into which the fixing metal fitting can be inserted on the outside of the inner surface of the box body or the cover, and attaching the part attached to the inner surface of the box body or the cover from the outside of the mounting hole penetrating the part. Alternatively, it is characterized in that the cover is inserted into a hole formed through the cover and then fixed and attached to the fixing metal fitting.

[0005]

The electrical equipment storage box as described above is designed in the same manner as the conventional electrical equipment storage box while the electrical equipment such as the circuit breaker and the branch terminal block is stored and fixed inside the box body and the cover. It is installed at a certain location and normally used by blocking the opening of the box body with a cover and locking it with a locking device for security, but a part attached to the inner surface of the box body or the cover, such as a locking rod. The locking metal fitting for locking the lock fitting is such that the tightening member and the fixing metal fitting for tightening and fixing the metal fitting face the inside of the pocket, and therefore are not exposed to the outside of the box body and the cover, and the tip of the tightening member and the fixing metal fitting. Since it cannot be removed from the outside with a tool such as a screwdriver, parts are removed, or the parts are locking metal fittings that lock the locking rod. Those no fear that the mischief open the cover.

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. Reference numeral 1 is a box body made of synthetic resin such as reinforced plastic, 2 is a cover made of synthetic resin provided on the opening 3 of the box body 1, and the cover 2 is a hinge (not shown). Is pivotally attached to. Reference numeral 4 denotes a pocket portion for inserting a fixing metal. The pocket portion 4 has two reinforcing ribs 1b, 1b projecting outside the side plate portion 1a of the box body 1 as shown in FIGS. The cover plate portion 5 is integrally formed with a space in which a fixing fitting can be inserted, and is formed by the side plate portion 1a.

Reference numeral 6 denotes a locking metal fitting of a locking device 7 which is a component to be mounted on the inner surface of the box body 1. The locking metal fitting 6 is mounted on the inner surface of the side plate portion 1a of the pocket portion 4 on the mounting plate portion 6a.
The fixing metal fitting 10 in which the fastening member 8 such as a screw is inserted from the outside of the mounting hole 6b provided through the mounting plate portion 6a into the through hole 9 provided in the side plate portion 1a and then inserted into the pocket portion 4. It is attached by being screwed and fixed to the female screw portion provided on the. Reference numeral 11 shown in FIGS. 3 and 4 is a rod bar that moves up and down by operation of the handle 12 of the locking device 7 attached to the front surface of one side of the cover 2 to engage and disengage from the locking metal fitting 6.

Reference numeral 13 shown in FIG. 4 is a roof member that covers the upper portion of the box body 1 and the cover 3.
Reference numeral 3 is a reinforcement in which a corrugated spring plate 16 attached forward is attached to the lower end of a holding plate 15 hung vertically in the center of the roof plate part 14 by bending the outside of the tip of the upper plate part 21 of the opening 2 of the box body 1. The folded back plate portion 22 for use is elastically locked and the lower portion of the rear plate portion 17 hung at the base end of the roof plate portion 14 is attached to the rear plate portion 18 of the box body 1 and then Board 1
The nut 19 embedded in the bolt 8 is attached with a bolt 20, and the spring plate 16 is locked from the rear of the folded plate portion 16 and the lower portion of the rear plate portion 17 is attached to the rear plate portion 18 of the box body 1. Can be easily attached.

The thus-constructed one is installed in a predetermined place as an electric device such as a circuit breaker and a branch terminal block attached inside the box body 1 or inside the cover 2, and is normally installed. The opening 3 of the box body 1 is closed by the cover 2 and the locking device 7 is used for locking for safety. In the present invention, a part to be attached to the inner surface of the box body 1 or the cover 2, for example, a locking metal fitting 6 of the locking device 7, and a mounting plate portion 6a are attached to the inner surface of the side plate portion 1a of the pocket portion 4. Mounting hole 6b transparently provided on 6a
The fastening member 8 such as a screw is inserted into the through hole 9 provided in the side plate portion 1a from the outside of the above, and is screwed and fixed to the female screw portion provided in the fixing metal fitting 10 inserted in the pocket portion 4. Therefore, the tip of the fastening member 8 and the fixing member 10 are completely hidden and are not exposed to the outside. The appearance is very good, and the parts such as the locking member 6 cannot be removed from the outside. There is no risk of mischief and it is excellent in security.

Further, since the through hole 9 provided in the box body 1 for inserting the tightening member 8, that is, the side plate portion 1a of the pocket portion 4 is covered by the cover plate portion 5 of the pocket portion 4, it is installed outdoors. Even if it does, it is not exposed directly to the wind and rain, so it is highly waterproof. In addition, in the embodiment, the case where the pocket portion 4 is provided in the box body 1 has been described, but it goes without saying that the pocket portion 4 may be provided in the cover 2 so that necessary parts can be attached.

[0011]

As is apparent from the above description, the present invention has a fastening member and a fastening member for fastening the fastening member and the like mounted on the inner surface of the box body or the cover, which are inserted into the pocket portion. Since it is not exposed to the outside of the box body and cover, and the tightening member and the fixing bracket cannot be removed from the outside with a tool such as a screwdriver, the parts can be removed or the parts can be locked. This is excellent in terms of security because it does not cause any mischief by opening the cover when it is a metal fitting for locking the rod. Therefore, the present invention is a great solution to the industry as a solution to the problems of the conventional electrical equipment storage box.
