Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switchgear in which a drawer-type device is housed in a box body, and a door mounting device such as an electric device or an electric meter is mounted on the inner surface of a front door.

[0002]

2. Description of the Related Art In this type of conventional switchgear, as shown in FIG. 4, a drawer-type device 4 is housed so that it can freely enter and leave a storage room 3 through a front opening 2 of a box 1 installed on a row board. A door mounting device 6 such as an electric device or an electric meter is mounted on the inner surface of the front door 5 that closes the opening 2.

When the drawer 4 is to be maintained, the front door 5 is opened, and the drawer 4 is pulled out from the front opening 2 of the box 1 to a position indicated by a chain line.

At this time, with the front door 5 in contact with the corners of the front door 5 of the adjacent box 1, the drawer 4 is prevented from hitting the door attachment 6 of the front door 5 so that the drawer 4 does not hit the door mounting fixture 6. The width dimension is increased.

[0005]

In the case of the conventional switchgear, the front door 5 can be opened only until it comes into contact with the front door 5 of the adjacent box 1, so that in this state,
The width of the box 1 must be increased so that the draw-out type device 4 does not hit the door attachment 6 of the front door 5.
However, there is a problem that the width dimension of the pattern becomes large.

In view of the above, the present invention is directed to a door mounting device such as an electric device having a front door, an electric meter, etc., when a drawer-type device housed in a box is pulled out from a front opening of the box. It is an object of the present invention to provide a switchgear capable of reducing the width of a box to a minimum size.

[0007]

In order to solve the above-mentioned problems, a switchgear according to the present invention is provided with a drawer-type device which is housed in a storage room through a front opening of a box installed on a train board so as to be able to enter and exit a storage room. A slide rail receiver fixed to the side surface of the storage chamber, a slide rail that slides on the slide rail receiver and is drawn out of the opening, and is supported by a hinge at a front end of the slide rail to close the opening. It comprises a front door and a door mounting device such as an electric instrument or an electric instrument mounted on the inner surface of the front door.

Therefore, the slide rail receiver is fixed to the side surface of the storage chamber of the box, and the front door is supported by the hinge at the front end of the slide rail that slides on the slide rail receiver. When pulling out the stored drawer-type equipment from the front opening, the door-mounting equipment such as electrical equipment and electric meters on the front door does not hinder the drawer-type equipment without taking the width of the box into account. Can be drawn to the minimum size.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment will be described with reference to FIG. The width of the box 7 is reduced, and a vertical support 9 is fixed to the front and rear of the side surface of the storage chamber 8 of the box 7, and the upper and lower portions of both supports 9 are respectively provided in the front-rear direction. Slide rail receivers 10 are fixedly mounted, and slide rails 11 slide on both slide rail receivers 10.
Are connected by a connecting member 12 having a vertical U-shaped cross section, and hinges 13 are provided on the upper and lower portions of the connecting member 12.
, And the front door 14 is supported by the hinge 13.

Then, similarly to FIG. 4, the front opening 1 of the box 7 is formed.
The draw-out type device 4 is stored so as to be able to enter and leave the storage room 8 from 5,
On the inner surface of the front door 14, a door attachment 6 such as an electric device or an electric meter is mounted.

Next, the structure of the slide rail receiver 10 and the slide rail 11 is as shown in FIG.
6 is a long board in the front-back direction of the slide rail receiver 10,
Reference numeral 17 denotes a lower plate having an L-shaped cross section, which is formed by bending leftward from the lower edge of the substrate 16, and lacking a portion corresponding to the front part of the substrate 16. Reference numeral 18 denotes an upper plate formed by bending the upper edge of the substrate 16 to the left, and a portion corresponding to the front portion of the lower plate 17 is missing. Reference numeral 19 denotes a front roller provided at a front portion of the substrate 16, and a gap is formed between the front roller 19 and the lower plate 17. Reference numeral 20 denotes a front stopper, which
Is formed to be bent leftward from the front end of. Reference numeral 21 denotes a rear stopper, which is formed by bending downward from the left end of the rear portion of the upper plate 18, and the rear end surface of the slide rail 11 abuts on and off.

Reference numeral 22 denotes a long board in the front-rear direction of the slide rail 11. The board 22 is bent rightward from the upper edge and the lower edge of the board 22 to form upper bent pieces 23 and lower bent pieces 24. The lower bent piece 24 is located in the gap between the front roller 19 and the lower plate 17. Reference numeral 25 denotes a rear roller provided on the rear portion of the substrate 22 of the slide rail 11, which slides on the upper plate 18 of the slide rail receiver 10 to prevent the rear portion of the slide rail 11 from floating, and A slide rail 11 is provided movably. 26 is the upper bent piece 23
And abuts on the front stopper 20 of the slide rail receiver 10 so as to be able to freely contact and separate therefrom.

FIG. 3A shows a slide rail receiver 1.
0 shows a state in which the slide rail 11 is stored and the front door 14 closes the front opening 15 of the box 7.

When the drawer 4 stored in the box 7 is pulled out from the front opening 15 of the box 7 from the state shown in FIG. 3A, as shown in FIG. 26 is pulled out to a position where it comes into contact with the front stopper 20 of the slide rail receiver 10, and at this position, FIG.
, The front door 14 is widely opened.

At this time, since the slide rail 11 is pulled out from the slide rail receiver 10, even if the front door 14 is opened at a large angle, it does not contact the front door 14 of the adjacent box 7, and When the drawer 4 is pulled out to the position indicated by the chain line in FIG.
Is not in the way, and the draw-out type device 4 can be easily pulled out.

Next, when the front door 14 is to be closed, the front door 14 is moved backward to a position where it comes into contact with the peripheral edge of the front opening 15 of the box 7, and the front door 14 is closed.

At this time, the slide rail 11 comes into contact with the rear stopper 21 of the slide rail receiver 10, and the slide rail 11 is stored in the slide rail receiver 10.

In the above embodiment, the number of the slide rail receiver 10 and the number of the slide rails 11 are two.
The quantity is determined according to the weight of the front door 14 and the door attachment 6.

[0019]

Since the present invention is configured as described above, it has the following effects. The switchgear of the present invention has a slide rail receiver 10 fixed to the side of the storage chamber 8 of the box 7, and a front door 14 that slides on the slide rail receiver 10.
Are supported by the hinges 13, so that when the draw-out type device 4 stored in the box 7 is pulled out from the front opening 15, the door mounting device 6 such as an electric device of the front door 14, an electric meter, or the like.
Does not become a hindrance, and the width of the box 7 can be set to the minimum size that the drawer-type device 4 can pull out.
