Abstract

(57) [Summary] [Purpose] To provide a board box door that can reduce the number of parts. [Structure] A door made of a thin plate that opens and closes an opening of a box 5, and a board name plate attachment surface 1 also serving as a reinforcement is formed in a concave shape on the surface of the door body A so that the back side of the door body A projects. A board name board is attached to the surface 1 on which the board name board is attached.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel box door such as a distribution board and a control panel.

[0002]

[Prior art]

 In some cases, the door of a panel box such as a distribution board is formed of a thin plate.

[0003]

[Problems to be solved by the device]

 However, there is a drawback that the door tends to be twisted and deformed as the door becomes larger as the door opens and closes. On the other hand, when a reinforcing member such as a beam is provided on the back surface of the door, the number of parts is increased. Therefore, an object of the present invention is to provide a door for a board box which can reduce the number of parts.

[0004]

[Means for Solving the Problems]

 The door of the board box of this invention is a thin plate door that opens and closes the opening of the box, and the board name plate attachment surface that also serves as a reinforcement is formed in a concave shape on the surface of the door body so that the back side of the door body protrudes. It is formed, and the board name plate is stuck to the board name board sticking surface.

[0005]

[Action]

 According to the configuration of the present invention, since the board name sticking surface is formed in a concave shape on the front surface of the door body so as to project to the back side of the door body, this board name sticking surface can reinforce the thin plate of the door body and reinforce the beam etc. Since it replaces the member, the number of parts can be reduced. Moreover, since the board name plate is attached to the board name sticking surface, the appearance is not impaired.

【Example】

 A distribution board to which an embodiment of the present invention is applied will be described with reference to FIGS. That is, as shown in FIG. 1, the door of the board box is a thin plate door that opens and closes the opening of the box 5, and the board name plate attachment surface 1 also serving as a reinforcement is attached to the back surface of the door body A. The door body A is formed in a concave shape so that the side protrudes, and the board name plate 2 is attached to the board name plate attaching surface 1. In the embodiment, the door body A is made of a thin steel plate having a thickness of about 0.6 mm, and is rotated between the handle 3 provided on the open / close end side of the door body A at the substantially central height and the upper end of the door body A. A round shape is formed on the shaft 4 side. In addition, the board name plate 2 shows the contents (not shown) of the distribution board such as symbols, trademarks and letters on the surface, which is attached to the board name plate pasting surface 1 with an adhesive. You may attach by the means of.

The box 5 uses a distribution box of a distribution board to which the door body A is attached as an example, and is attached to a fixed rail 6 attached to a wall surface 9 by a hooking piece and an attaching screw (not shown). This box 5 has an opening 7 at the upper and lower ends, and a plurality of boxes 5, 5'are attached to the fixed rail 6 so as to be vertically continuous, and the opening 7 is provided with a lid (not shown) after wiring. ing.

FIG. 2 shows the inside of the box 5, in which the breaker 10 is fixed and wired to the internal unit frame 8 fixed to the box 5. An inner lid 11 is supported by the inner unit frame 8 and covers the breaker 10. 3 to 5 show the door main body A, and the peripheral portions 13 and 14 of the door main body A are bent to the back surface side to serve as thickness and reinforcement, and the board name plate attachment surface 1 is provided on the front surface side as shown in FIG. A handle mounting hole 12 is formed on the back side of the handle by extrusion, and the handle 3 is mounted therein. Reference numeral 15 is a corner member.

According to this embodiment, since the board name sticking surface 1 is formed in a concave shape on the front surface side of the door body A so as to project to the back surface side of the door body A, the board name sticking surface 1 is Since the thin plate can be reinforced and it can be used as a substitute for reinforcing members such as beams, the number of parts can be reduced. Moreover, since the board name plate 2 is attached to the board name attaching surface 1, the appearance is not impaired. Another embodiment of this invention is shown in FIGS. That is, in FIG. 6, the board name plate attachment surface 1 is formed in an arrow shape, and the name plate 2 having a similar shape to this is attached to the concave surface. FIG. 7 is formed in the shape of the letter A, and a name plate 2 having a shape similar to this is attached to the concave surface. All of them have the same working effect as the above-mentioned embodiment.

[0010]

[Effect of device]

 According to the door of the board box of the present invention, the board name sticking surface is formed in a concave shape on the front surface of the door body so as to project to the back side of the door body, and thus the board name sticking surface can reinforce the thin plate of the door body. Since it replaces a reinforcing member such as a beam, the number of parts can be reduced. Moreover, since the board name plate is attached to the board name sticking surface, there is an effect that the appearance is not damaged.
