Abstract

PROBLEM TO BE SOLVED: To make rainwater hard to be collected in a draining part and to prevent the rainwater from intruding into an enclosure main body by a method wherein slopes are given from the apex of the upper intermediate part of an opening provided in the enclosure main body toward the respective left and right side plates of the enclosure main body in a draining part formed by bending the peripheral edge of the opening. SOLUTION: An opening 4 is provided in the front surface of an enclosure main body 2 of an electrical equipment housing enclosure 1. The opening 4 provided in the main body 2 is bent and a draining part 7 is formed into a groove shape. In the upper draining part 7 in the opening 4, the center part is made highest and slopes are respectively given from the center part made highest toward the respective left and right side surfaces of the main body 2. Thereby, drainage of the draining part 7 is improved, it is eliminated that rainwater overflows into the draining part 7 and intrudes into the main body 2 and the waterproofness of the enclosure main body 2 is enhanced. Moreover, when the door of the box body 1 is shut, a door body 5 is prevented from being uneven because the upper part of the door body 5 is conformed to the apex of the upper draining part 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draining structure for preventing water from entering the box body in a box for housing electrical equipment.

[0002]

2. Description of the Related Art A box body 21 for storing electrical equipment is a box body 22.
The front surface 23 is opened, and the opening 24 is covered by a door body 25. In the prior art, as shown in FIG. 3, a drainer 26 is formed by bending a peripheral edge of the opening 24 of the electrical equipment housing box 21, and a drainer 27 above the opening 24 is also provided horizontally along the opening. . In addition, as shown in FIG.
A packing 28 was manually attached to the gap between the box body 22 and the drainer 26 to prevent rainwater from entering from the outside.

[0003]

However, according to the above-mentioned conventional technique, the drainer 26 provided on the periphery of the opening 24 is provided.
Since the groove part of is flat, water easily collects in the drainer 26, and when there is a lot of rainfall, it overflows from the drainer 26,
There was a risk of rainwater entering the box body 22. Also,
Packing 2 provided between the door body 25 and the box body 22
Since No. 8 was attached by hand, there was a risk that the attachment position would shift and rainwater would enter the inside of the box body.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a box body for storing electrical equipment is provided which prevents rainwater from collecting in a drainer formed at the end of the opening of the box body and prevents rainwater from entering the box body. The purpose of the structure is to bend the periphery of the opening to form a drainer, with the middle part of the upper part of the opening being the apex of the drainer, and sloping from the apex toward the left and right side plates respectively. That is.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION An opening is provided on the front surface of a box body,
A drainer is formed on the periphery of this opening by bending. Since the drainer at the upper part of the opening is inclined to the left and right with the central portion as the apex, rainwater flows according to the inclination of the drainer, does not collect in the drainer, and does not enter the box body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the structure of a box for accommodating electric equipment according to the present invention will be described with reference to the accompanying drawings of FIGS.

FIG. 1 is an explanatory view of a box for storing electric equipment according to the present invention. An opening 4 is provided in a front surface 3 of a box body 2 of the box 1 for storing electric equipment. This opening 4 is
Although it is covered by the door body 5, the door body 5 is attached by a hinge 6 and can be opened and closed by a rotating operation.

The opening 4 of the box body 2 is bent at its peripheral edge to form a drainage 7 in a groove shape. As shown in FIG. 1, the drainer 7 in the upper part of the opening 4 has the highest central portion and is inclined toward the left and right sides respectively. As shown by the arrow in FIG. 2, the rainwater flows down without accumulating according to the inclination of the water drain 7 of the box body 2.

The door body 5 covers the entire opening 4, and the lip of the door body 5 is brought into contact with the central portion which is the apex of the drainer 7 in the upper part, and when the door body 5 is closed, the door body 5 is drained. Thus, the door body 5 can be prevented from falling down.

The apex of the drainer 7 may be located at any position of the drainer above the opening 4, and can be appropriately changed without departing from the gist of the present invention.

[0011]

As described above, according to the present invention, the periphery of the opening is bent to form a drainer, and in the drainer, the upper portion of the opening has the middle portion as the apex, and from the apex to the left and right side plates, respectively. Since it is inclined toward the drainage, the drainage of the drainage is improved, rainwater does not overflow and does not enter the box body, and the waterproofness of the box body is improved. Moreover, when the door is closed, the top of the door is aligned with the top of the drainer, which prevents the door from falling down. Since the central part of the draining part is made high, the frontage is widened and the equipment can be easily installed inside the box. When the door body is closed, the door body is supported at the apex of the drainer, so that the door body can be prevented from falling down.
