Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a box structure of a switchboard or a control panel (hereinafter referred to as a switchboard, etc.), and more particularly to a switchboard or the like to be applied when a plurality of boxes are arranged in a row and concentrated.

[0002]

[Prior art]

 Conventionally, when a plurality of switchboards, etc. are arranged in a row in a centralized arrangement (hereinafter referred to as a row board arrangement), a gap may occur between adjacent boxes, so Fig. 4 (a) shows As described above, the side plates 2 and 2'are fixed to both side surfaces of the lower frame 1 and the upper frame 3, and the gasket G is inserted between the adjacent boxes 10 and 10 ', and screws for connecting the boxes are connected. N was increased to prevent the formation of gaps. In addition, as shown in FIG. 4 (b), adjacent boxes 10 and 10 'share one side plate 2, and a plurality of boxes are integrally configured to be arranged in a row board. It was preventing the gap between the bodies.

[0003]

[Problems to be solved by the device]

 However, with the former configuration, there is a risk that a lot of adjustment work will occur during installation due to deterioration of the function due to deterioration of the gasket and an increase in the error in the finished external dimensions after the row board due to the gasket thickness. was there. Further, in the latter configuration, a gap between the boxes is not generated, and an error in finishing size does not increase, but when the side plate is configured as a strength member, the box 10 for each surface is formed. In ', there is one side plate 2 but the other side plate 2'is absent, so it becomes unstable, and it is not possible to transport the box in units of one surface. Therefore, the box cannot be divided in units of one surface and must be transported in a state in which a plurality of surfaces are joined without fail, which necessitates a large transporting means, and the cost of the transporting means increases. Further, it is difficult to properly change the number of row boards at the time of installation, and the row board configuration lacks flexibility. An object of the present invention is to provide a box body such as a switchboard having a large dustproof effect, easy transportation, and a flexible row board configuration.

[0004]

[Means for Solving the Problems]

 The present invention relates to a box body such as a switchboard having a quadrangular lower frame, a rectangular upper frame which is the same as the lower frame, and two side plates whose both ends are fixed to both side surfaces of the lower frame and the upper frame. The side plate having a width in the depth direction of the length of the side face of the lower frame or the upper frame divided into two, and the side face of one of the side plates are aligned with the front faces of the lower frame and the upper frame. , A bolt for fixing the side surface of the other side plate to the rear surface portions of the lower frame and the upper frame so as to be fixed, and for connecting the side plates of the box body adjacent to the corners of the side surface portions of the lower frame and the upper frame, respectively. It is provided with a hole.

[0005]

[Action]

 Set the width of the side plate of the box to the length in the depth direction of the box divided into two, match the side of one side plate with the front part of the box, and match the side of the other side plate with the rear part of the box. Since they are fixed, the boxes can be transported one by one. When the boxes are arranged in rows, one side plate of the other box is fixed adjacent to the other side plate of the one box. Then, the side surface of the one side plate of the other box coincides with the front surface of the one box, and the front surfaces of the adjacent boxes are integrally joined together.

[0006]

【Example】

 The present invention will be described with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, in which a side plate 2 having a width B obtained by dividing a length L of the side part 11 in the depth direction into two is formed on one side part 11 of a lower frame 1 formed in a quadrangle. The lower end is fixed. At that time, the side surface 21 of the side plate 2 is made to coincide with the front surface portion 12 of the lower frame 1. The upper end of the side plate 2 is fixed to one side surface portion 31 of the upper frame 3 formed in a quadrangle like the lower frame 1 so that the side surface 21 of the side plate 2 coincides with the front surface portion 32 of the upper frame 3. . On the other side surface portion 13 of the lower frame 1, a lower end of a side plate 2'having the same size as the side plate 2 is fixed so that the side surface 21 of the side plate 2'is aligned with the rear surface portion 14 of the lower frame 1. The upper end of the side plate 2'is fixed to the other side surface portion 33 of the upper frame 3 so that the side surface 21 of the side plate 2'is aligned with the rear surface portion 34 of the upper frame 3. Bolt holes 15 and 35 for connecting adjacent side plates are provided at respective corners of the side surface portions 11, 13, 31, and 33 of the lower frame 1 and the upper frame 3. In this way, when a plurality of boxes 10 and 10 'configured by connecting the lower frame 1, the side plates 2 and 2'and the upper frame 3 with bolts are arranged in rows, as shown in FIG. Adjacent to the side plate 2'of the box 10 shown, the side plate 2 of the box 10 'shown by the alternate long and short dash line is fixed to the lower frame 1 and the upper frame 3 of the box 10. Then, as shown in FIG. 2, the side surface 21 of the side plate 2 of the box 10 ′ coincides with the front portions 12 and 32 of the lower frame 1 and the upper frame 3 of the box 10, and the front surfaces of the boxes 10 and 10 ′. The boxes 10 and 10 'adjacent to each other are integrally joined in a state where they are aligned, and both side plates 2 and 2'are shared.

[0007]

[Effect of device]

 As described above, according to the present invention, each box is configured to be able to be transported one by one by the lower frame, the side plate, and the upper frame, and the side plate is shared with the adjacent box so that the space between the boxes is Since it does not occur, it is possible to carry the paper one by one, which is the minimum unit, and the dustproof effect is improved, and the accuracy of the finished dimensions when the rows are arranged is improved. Furthermore, when assembling parts and wiring work on a single box, there is an effect that the work space is wide and work efficiency is improved because half of the side plate in the depth direction is open.
