Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric equipment storage box used for a cubicle or the like.
[0002]
[Prior art]
A conventional electric equipment storage box used for a cubicle or the like has a welded structure as shown in FIG. As shown in (1), the assembly method is as follows. First, a rectangular frame body 2 assembled by welding for the number of doors is placed on the front and back of the square base 1 and bolted to each other. The vertical beam 3 is bolted between the front and rear frames 2 and 2 as shown in Fig. 3, the horizontal beam 4 and the waterproof plate 5 are bolted as shown in (3), and the side plate 6 is bolted from the outside as shown in (4). Finally, as shown in (5), the roof 7 and the door 8 are attached.
[0003]
In this case, the door 8 is provided with a handle with a key, and the door 8 is opened as necessary to check the electrical equipment stored therein. On the other hand, the side plate 6 is usually removed by removing the bolts from the inside only in the case of replacement work of a transformer or an electric device housed inside. However, when removing the bolts of the side plate 6 from the inside, there are cases where it is difficult to work with electrical equipment or the like housed inside. Further, the method of removing the bolts of the side plate 6 from the outside has good workability, but there is a risk of being tampered with, and the development of an electric equipment storage box that cannot be removed from the outside and that has good workability has been developed. It has come to be desired.
[0004]
[Problems to be solved by the invention]
The present invention solves the conventional problems as described above, and even if the mounting bolts of the side plate 6 are removed from the outside, the side plate 6 cannot be removed and can exhibit excellent security. It was completed for the purpose of providing an electric equipment storage box that is simple and inexpensive.
[0005]
[Means for Solving the Problems]
An electrical equipment storage box of the present invention made to solve the above-mentioned problem is an electrical equipment storage box formed by bolting a side plate from the outside to a frame, and a through hole is formed in the side plate. At the same time, through-holes are also formed in the frame at positions corresponding to the through-holes, and drop-type L-shaped pins are inserted into the through-holes from the frame side toward the side plate to lock the frame and the side plate . Thus, even if the side plate is pulled outward, the side plate is not detached from the frame body, and the side plate is further bolted from the outside .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 2, a rectangular frame 2 assembled by welding the number of doors is placed on the front and back of the rectangular base 1 and bolted to each other. The vertical beam 3 is bolted between the two, and the horizontal beam 4 and the waterproof plate 5 are further bolted to form the frame body 10, and the side plate 6, the roof 7 and the door 8 are attached to the frame body 10. Is basically the same as the conventional electric equipment storage box.
In addition, 7a is a lifting metal fitting provided on the roof 7, and 8a is a handle with a key provided on the door 8. Further, in the illustrated example, an electric device storage box having two doors is shown.
[0007]
In the present invention, a through hole 11a is formed in the side plate 6 and a through hole 11b is also formed in a support of the frame body 10 at a position corresponding to the through hole 11a. A frame is formed in the through holes 11a and 11b. It has a characteristic configuration in that a drop-type L-shaped pin 12 is inserted from the body side toward the side plate and the frame body 10 and the side plate 6 are locked.
That is, the side plate 6 is fastened and fixed to the frame body 10 by bolts 13 from the outside. As shown in FIG. 3, the side plate 6 is bent at the end portion to form a column portion. The through hole 11a is formed on the inner side of the column part, and on the other hand, a through hole 11b is also formed at the same position as the through hole 11a of the portion to be the support of the frame body 10, as shown in FIG. Thus, the frame body 10 and the side plate 6 are locked by inserting the drop-shaped L-shaped pin 12 from the frame side toward the side plate. Thereby, even if the side plate 6 is pulled outward, it does not come off from the frame body 10, and the L-type pin 12 cannot be seen at all from the outside, so it is impossible to remove the side plate 6 from the outside.
[0008]
Further, in the illustrated example, any one edge portion of the side plate 6 is rotatably attached to the frame body 10 by a hinge 14, and after the L-shaped pin 12 is pulled out, the hinge 14 is centered. The side plate 6 can be opened outward.
In the illustrated example, only one L-shaped pin 12 is attached to the lower portion, but it is needless to say that an arbitrary number of L-shaped pins 12 may be attached at an arbitrary location depending on the installation location, design conditions, and the like. is there. The same applies to the mounting location and the number of bolts 13.
[0009]
In this configuration, the side plate 6 is formed with a through hole 11a and the frame body 10 is also formed with a through hole 11b at a position corresponding to the through hole 11a, and the frame body side is formed in the through holes 11a and 11b. Since the L-shaped pin 12 is inserted toward the side plate and the frame body 10 and the side plate 6 are locked, the side plate 6 cannot be removed even if the mounting bolt 13 of the side plate 6 is removed from the outside. Moreover, the presence of the L-shaped pin 12 is not visible at all from the outside, and exhibits excellent security. Therefore, it is not necessary to use expensive parts such as a handle with a key on the side plate 6, and an inexpensive product can be provided. On the other hand, when it is necessary to remove the side plate 6, the bolt 13 is removed, the door 8 is opened, and the L-shaped pin 12 is removed from the inside, so that it can be easily opened and excellent workability is achieved.
[0010]
【The invention's effect】
As is clear from the above explanation, the present invention can exhibit the excellent security because the side plate 6 cannot be removed even if the mounting bolts of the side plate 6 are removed from the outside. It is simple and inexpensive.
Therefore, the present invention greatly contributes to the development of the industry as an electrical equipment storage box that has eliminated the conventional problems.
