Description

  The present invention relates to an electric equipment storage box that enables wiring between adjacent cabinets.

  Rack-type electrical equipment storage boxes containing a large number of electrical equipment are widely used particularly in the field of communications. Such an electric device storage box is partitioned into a plurality of levels in the vertical direction by a partition plate, and the user of each level may be different. Moreover, it may be necessary to draw the wiring from the electric device into the adjacent electric device storage box.

  For this reason, as shown in Patent Documents 1 and 2, an opening for wiring or an opening for ventilation is formed on the side plate of the electrical equipment storage box to draw the wiring into another adjacent electrical equipment storage box. To be done. Since such an opening usually needs to be closed, in Patent Document 1, a horizontal frame is attached above and below the opening to hold the slide panel slidably. In Patent Document 2, a frame is attached around the opening to hold the slide panel slidably.

  However, it is usual that a plurality of such openings are provided on the side plate, and the number of openings is particularly large when provided at each stage. Therefore, in the structure in which the frame is attached to each opening as in Patent Documents 1 and 2, there are problems that the number of parts increases, the number of processing steps increases, and the cost increases.

  Accordingly, the object of the present invention is to solve the above-described conventional problems, and to provide a low-cost electric device having a side wall of the box with an opening for drawing in or exhausting air and a slide panel covering the opening. It is to provide a storage box.

  The present invention made in order to solve the above-mentioned problem is an electrical equipment storage box in which an opening for wiring drawing or intake / exhaust is formed on a side plate of the box, and a closing portion for closing the opening, and an opening A slide panel provided with a hook portion that engages with upper and lower end edges is slidably held in the opening.

  Note that, as in the second aspect, the closing portion may be formed with a slide restricting portion for restricting the slide.

  As in claim 3, the slide panel fixing portion is formed by a long hole formed in the slide panel that extends in the sliding direction and a fixing screw that is provided in the slide plate and is screwed into the side plate. It can be a structure.

  Furthermore, it is preferable to have a structure in which an opening / closing regulating portion is provided on each of the front and back surfaces of the slide panel.

  The electrical equipment storage box of the present invention is slidably held in the opening by engaging the hooks formed on the slide panel with the upper and lower edges of the opening. There is no need to form a frame around it. For this reason, cost reduction can be aimed at.

  According to the second and third aspects of the invention, the slide panel can be fixed at an arbitrary position by the slide restricting portion, and the slide panel can be prevented from falling or rotating.

  According to the invention of claim 4, by providing the open / close restricting portions on both the front and back surfaces of the slide panel, the slide panel can be removed unless the fixing portion is removed from one side even if the fixing portion is removed from one side of the slide panel. Cannot slide. For this reason, security can be ensured even when the managers of adjacent electrical equipment storage boxes are different.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing the external appearance of the electrical device storage box 100, and only two adjacent electrical device storage boxes 100 are shown, but in reality, a large number of electrical device storage boxes 100 are closely arranged. It is what is done. Reference numeral 1 denotes a side plate, which shows four openings 2 and a slide panel 3 covering each opening 2. These openings 2 are openings for drawing in wiring or intake / exhaust, and are normally closed by a slide panel 3. In this example, the inside of the electric equipment storage box 100 is divided into two upper and lower stages, but it goes without saying that the present invention is not limited to this. In addition, the opening part 2 is only what opened the side plate 1 in the rectangular shape.

  2 and 3 are perspective views of the slide panel 3 according to the first embodiment viewed from both sides. As shown in the figure, the slide panel 3 includes a flat-plate-shaped blocking portion 4 having a size capable of closing the opening 2, and a flange portion 5 protruding vertically from the blocking portion 4. In this embodiment, the flange portion 5 is formed by bending a vertical edge on one side of the closing portion 4 perpendicular to the direction of the side plate 1. The height of the flange portion 5 is slightly larger than the height of the opening portion 2. The flange portion 5 functions as an operation portion when opening and closing the slide panel 3. In addition, the flange part 5 can also be divided | segmented up and down.

  The connecting portion 6 between the closing portion 4 and the flange portion 5 is formed with notched hook portions 9 and 10 that engage with the upper and lower edges 7 and 8 of the opening 2. These hook portions 9 and 10 are U-shaped, and at least the thickness of the side plate 1 extends to the side plate 1 side from the back surface of the closing portion 4. For this reason, it is possible to fit and hold the shoji or bran between the openings 2 so that the shoji or bran is held between the “kamoi” and the “sill”.

  However, since the hooking portions 9 and 10 are formed only on one vertical edge of the closing portion 4, there is a possibility that the slide panel 3 rotates in a direction away from the side plate 1 with the hooking portions 9 and 10 as the center. Therefore, in this embodiment, as a slide restricting portion for preventing the slide panel from rotating and falling, long holes 11 are formed in the slide direction (horizontal direction) at the upper and lower ends of the slide panel 3 and screwed into the side plate 1 inside thereof. A fixing screw 12 is provided to form a fixing portion of the slide panel 3. Therefore, if the fixing screw 12 is loosened, the slide panel 3 can be slid in parallel with the side plate 1 while being guided by the fixing screw 12, and can be fixed at an arbitrary position by tightening the fixing screw 12. The fixing screw 12 prevents the slide panel 3 from falling into the side plate 1 and prevents sliding by screwing an opening / closing regulating portion 14 described later even when not firmly tightened. It is possible to do. Thus, since the slide panel 3 can be slidably held in the opening 2 with a simple structure without providing a frame around the opening 2, the cost is low. FIG. 4 shows a state in which the slide panel 3 is slid halfway.

  In addition, it is preferable that the slide panel 3 is provided with the opening / closing regulating portions 14 on both the front and back surfaces. In this embodiment, the opening / closing restricting portion 14 is a screw, and penetrates the slide panel 3 and is screwed to the side plate 1. For this reason, unless the opening / closing restricting portion 14 is released from both sides, the slide panel 3 cannot be slid to open the opening 2, and security is ensured even when the managers of the adjacent electrical device storage boxes 100 are different. be able to. In addition, as in the second embodiment shown in FIGS. 5 and 6, a plurality of screw insertion hole rows 13 are formed, and the opening / closing regulating portion 14 is sequentially replaced in accordance with the position of the slide panel 3. It is.

  FIG. 7 is a view showing another embodiment (third embodiment) of a slide restricting portion for preventing the slide panel 3 from rotating and falling. In this embodiment, the flange portion 5 is fixed to the center portion of the slide panel 3 by welding or the like. If the flange portion 5 is provided in the center portion in this way, there is an advantage that an operation of sliding the slide panel 3 with a fingertip can be easily performed. As another embodiment of the slide restricting portion, although not shown, a structure in which only the hooking portions 9 and 10 are formed without providing the flange portion 5, a plurality of the hooking portions 9 and 10 are formed or widened in the sliding direction. By doing so, the slide panel 3 may be prevented from falling or rotating.

  The opening 2 may be used not only for drawing in the wiring but also for intake and exhaust of air. For example, as shown in FIG. 8, a wraparound prevention blank panel 16 for preventing warm air from flowing into the cooling air intake is formed on the mount rail 15, and the cooling air is sent to the adjacent electrical equipment storage box 100. In some cases, the slide panel 3 may be opened to blow air from the opening 2. However, in this case, the blank panel 16 may be in the way, and it may not be possible to provide the fixing portion using the long hole 11 as described above.

  In such a case, as in the fourth embodiment shown in FIG. 9 and FIG. 10, the screw hole as the fixing portion 17 is directly formed in the flange portion 5, and the slide panel 3 is made into the blank panel 16 by the fixing screw 12. It is also possible to fix directly. In this case as well, the relationship between the opening 2 and the slide panel 3 is the same as in the first embodiment.

  As described above, according to the present invention, the slide panel 3 that covers the opening 2 formed in the side plate 1 of the box can be incorporated at a low cost, and the cost is lower than that of the conventional structure. There is an advantage that there is no risk of security problems.
