A stud 11 is secured to a planar arm part 8 integrated with the tubular part 7 of the hinge 6. A packing 12 is applied to the stud 11 which is then inserted into a hole 13 made through the front plate 5 and tightened by means of a nut 16. A recess 17 for receiving the packing 12 is formed by the front plane 5 having a seat hole 18 larger than a hole 13 made through the frame body 2 of the box body 1. The planar arm part 8 and the box body 1 to be integrated with the tubular part 7 of the hinge 6 are painted at the stage of components and then they are assembled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door mounting device for an outdoor type switchboard which is waterproof.

[0002]

2. Description of the Related Art FIG. 3 is a sectional view of a main part of a conventional example. In the figure, a box body 1 is composed of a frame body 2 such as an angle steel forming a skeleton, a wall plate 3, and a front plate 5 having a J-shape or the like to form an opening 4 and have drip-proof property. , Each is fixed. The flat plate arm portion 8 integrated with the tubular portion 7 of the hinge 6 is fixed to the front plate 5 at a welding point 9 and then coated with the box body 1. The welded portion 9 of the flat plate arm portion 8 may be partly strong, but rainwater easily enters the gap between the flat plate arm portion 8 and the front plate 5 and is easily rusted. In addition,
The shaft fitted in the tubular portion 7, the tubular portion on the door side, and the door are not shown here.

[0003]

In the above-mentioned conventional example, since the welding portion 9 covers the entire circumference of the flat plate arm portion 8 in order to prevent the intrusion of rainwater, the number of working steps is large. Also, adjusting the dimensions of the opening and the door requires skill and a jig in welding. An object of the present invention is to provide a door mounting device for an outdoor type switchboard in which the hinge of the door is easily attached to the opening of the box body to ensure waterproofness and the dimensional accuracy of the opening and the door can be easily secured. is there.

[0004]

A door mounting device for an outdoor type switchboard according to the present invention has a door for opening and closing an opening of a box and the opening connected to each other by a hinge, and a stud fixed to a flat plate arm portion of the hinge. The packing is fitted, passed through the hole of the front plate of the opening, and fixed with the nut. At this time, the front plate is provided with a recess for embedding the packing, or the recess is formed by the front plate having a seat hole having a diameter larger than that of the hole provided in the frame of the box body.

[0005]

According to this structure, the packing exerts a waterproof function, and since the gap between the flat plate arm portion and the box body can be painted at the stage of parts, it does not rust even if water collects. If the recess is provided, the waterproof property is further improved, and the recess can be easily formed by pressing the frame and the front plate. Therefore, the hinge of the door can be easily attached to the opening of the box with a nut to ensure waterproofness, and the dimensional accuracy of the opening and the door can be easily ensured.

[0006]

FIG. 1 is a sectional view of the essential part of the embodiment, and FIG. 2 is a diffusion exploded view of FIG. 1. In the conventional example and those given the same reference numerals, they have approximately the same function. In the figure, a box body 1 includes a frame body 2 such as angle iron forming a skeleton and a wall plate 3
And a front plate 5 having a J-shape or the like to form the opening 4 and have a drip-proof property, and they are fixed to each other. The tubular portion 6b on the door 10 side is fitted to the tubular portion 7 of the hinge 6 by the shaft 6a to form the hinge 6, and the tubular portion 6b is fixed to the door 10.

A feature of the embodiment is that a stud 11 is fixed to a flat plate arm portion 8 integrated with the tubular portion 7 of the hinge 6. The packing 12 is fitted into the stud 11 and the opening 4
Through the hole 13 of the front plate 5 of the washer 14 and the spring washer 1
Fix with nut 16 via 5. The front plate 5 may be provided with a recess 17 in which the packing 12 is embedded, and the recess 17 may be formed by the front plate 5 having a seat hole 18 having a diameter larger than the hole 13 provided in the frame 2 of the box body 1. . The flat plate arm portion 8 and the box body 1 integrated with the tubular portion 7 of the hinge 6 are painted at the stage of parts and then assembled.

According to such a structure, the packing 12
Has a waterproof function, and since the gap between the flat plate arm portion 8 and the box body 1 can be painted at the stage of parts, it does not rust even if water collects. It is better to provide the concave portion 17, or the concave portion 17 can be easily and accurately formed in the pressing process of the frame body 2 and the front plate 5. Therefore, the hinge 6 of the door 10 is easily attached to the opening 4 of the box 1 with the nut 16 to ensure waterproofness, and the dimensional accuracy of the opening 4 and the door 10 can be easily ensured.

[0009]

According to the door mounting device of the outdoor type switchboard of the present invention, the packing exerts a waterproof function, and since the gap between the flat plate arm portion and the box body can be painted at the stage of parts, it rusts even if water collects. There is no. If the recess is provided, the waterproof property is further improved, and the recess can be easily formed by pressing the frame and the front plate. Therefore, the hinge of the door can be easily attached to the opening of the box with a nut to ensure waterproofness, and the dimensional accuracy of the opening and the door can be easily ensured.
