Abstract

PURPOSE:To limit the projecting distance of panel board from a box when the panel board rotates by arranging a body for supporting the panel board rotatably at a position closer by a predetermined distance to the intermediate section than one lateral end of the panel board. CONSTITUTION:A supporting body 6 is fixed to the lower horizontal frame of a box 1 at a position closer by a predetermined distance to the intermediate section than one end lateral end of a panel board 2. upper supporting section 9 to be fixed to a horizontal frame 5a is fixed immediately above lower supporting section 8. When the panel board 2 is rotated, the other end of the panel board 2 rotates with such radius as shorter by a predetermined dimension than the lateral dimension of the panel board 2. Since large space is not required for rotation of the panel board 2 in front of the box 1, inspection and wiring of electrical parts on the rear side of a panel board 6 can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a panel rotation type control panel provided with a rotatable panel plate on which electrical parts are mounted.

[Conventional technology]

Conventionally, as described in, for example, Japanese Utility Model Application Publication No. 57-133209, a box installed in a building, a panel board provided in the box and on which electrical parts are mounted,
A panel rotation type control panel has been proposed that includes a support body attached to the box described above and rotatably supporting one end of the panel plate.

[Problem to be solved by the invention]

By the way, in the above-mentioned conventional panel rotation type control panel, the panel plate is supported by a support at one end, so when the panel plate is rotated, the other end of the panel plate is The problem was that it rotated with a radius that was almost the same as the width of the panel board, and it protruded far ahead of the box. For this reason, it was necessary to secure a relatively large space in front of the box for the rotation of the panel board. On the other hand, if sufficient space cannot be secured, the rotation of the panel board will be restricted, making it difficult to inspect electrical components on the back side of the panel board or perform wiring work. was there.

The present invention has been made in view of the actual situation in the prior art as described above, and its purpose is to propose a panel rotation type control panel that can reduce the distance that the panel plate protrudes forward from the box when rotating. It's about doing.

[Means to solve the problem]

To achieve this objective, the present invention includes a box installed in a building, at least one panel plate provided in the box and to which electrical components are attached, and a panel plate attached to the box that is rotatable. In the panel rotating type control panel, the support body is provided at a position a predetermined distance from one end of the panel board in the width direction toward the middle part.

[Effect]

In the present invention, as described above, since the support body is provided at a position closer to the middle part by a predetermined distance from one end of the panel board in the width direction, when the panel board is rotated, the other end of the panel board is The portion rotates at a radius that is shorter than the width of the panel plate by the predetermined dimension described above, that is, the distance that the panel plate projects forward from the box when the panel plate is rotated can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The rotating panel control panel of the present invention will be described below with reference to the drawings.

Figures 1 to 3 are explanatory diagrams showing one embodiment of the panel rotating control panel of the present invention, where Figure 1 is a front view, Figure 2 is a plan view, and Figure 3 is an enlarged view of the support portion. FIG.

The panel rotating control panel of this embodiment shown in FIG. 1, like the conventional one, includes a box 1 installed in a building (not shown), a relay 3, a printed board 4, etc. A panel board 2 on which electrical components are mounted, a support 6 attached to the box 1 and rotatably supporting the panel board 2, and a cover 7 attached to the back side of the panel board 2.
Contains.

In this embodiment, the support body 6 is the panel board 2.
A lower support part 8 is attached to the lower horizontal frame 5 of the box 1 at a position a predetermined dimension closer to the middle than one end in the width direction of the box, and a lower support part 8 is attached to the lower horizontal frame 5 of the box 1 at a position directly above the lower support part 8. 1, and an upper support part 9 attached to the upper horizontal frame 5a of 1. Moreover, the lower support part 8 is
As shown in FIG. 3, a fixed part 11 bolted to the lower horizontal frame 5, a shaft 12 projecting upward from this fixed part 11, a bearing 13 into which this shaft 12 is fitted, and this bearing 13. It is composed of a movable part 14 that is fixedly installed and bolted to the panel plate 2. The upper support body 9 also has a similar configuration. Although not shown, a ball is provided which is inserted into the bearing 13 and comes into contact with the upper end of the shaft 12.
The weight of the panel board 2 is supported via this ball.

In this embodiment, when the panel board 2 is rotated when inspecting the relay 3, printed circuit board 4, etc. or performing work such as wiring on the back side of the panel board 2, the end portion 2a of the panel board 2
It rotates about the lower support part 8 and the upper support part 9 at a radius corresponding to the width dimension W of the panel board 2 minus the predetermined dimension L (>w/2). For example, when the panel plate 2 is rotated to the position indicated by the broken line in FIG. 2, the operator is supposed to work on the back side of the panel 2.

In the embodiment configured in this way, the turning radius of the end portion 2a of the panel board 2 can be made small, that is,
The distance by which the panel plate 2 projects from the box 1 during rotation can be reduced. In addition, while the panel board 2 is in a rotated state, the operator can work on the back side of the panel board 2 without any hindrance. Since the side portions 1a are separated from each other, it is possible to prevent the relay 3, printed board 4, etc. mounted on the panel board 2 from colliding with each other.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to reduce the turning radius of the end of the panel plate, that is, it is possible to reduce the distance that the panel plate 2 protrudes from the box when rotating.
Therefore, there is an effect that it is possible to easily inspect electrical components on the back side of the panel board, and perform wiring work, etc., without requiring a large space in front of the box for rotating the panel board.
