Description

[Technical field]

[0001] The present invention relates to an electric equipment storage box, and more particularly to an electric equipment storage box to be installed outdoors. [Background technology]

[0002] In addition to freestanding electrical equipment storage boxes installed outdoors like cubicles, there are also boxes that are fixed to the wall of a building. Even when they are installed on a wall, a roof is installed on the top of the box body to protect it from rainwater. In the case of a free-standing configuration, there is space all around, so it is easy to install the box body at the installation location and then attach the roof body; however, in the case of a configuration in which the box body is fixed to a wall, there is no space at the back of the installed box body, so the roof body also has a special shape with no protrusions on the back. Furthermore, when the box body is fixed to a wall, in order to make it possible to attach the roof body after the box body is installed, a method is adopted that allows attachment even if there is no space behind it. For example, in Patent Document 1, a recessed locking portion is provided on the front and back of the box body, and locked portions that lock onto the locking portions are formed hanging down at the front and back of the roof body, making it possible to attach the roof body by covering it from above.

[0003] [Patent Document 1] JP 2004-229470 A Summary of the Invention [Problem to be solved by the invention]

[0004] As in Patent Document 1 mentioned above, by making it possible to attach the roof body by covering the box body from above, it was possible to attach the roof body even in locations where there was no space for maneuvering at the back of the box body. However, because locking portions are provided on the back side as well as the front side of the box body, it was difficult to attach the roof body after the box body was completely fixed to the wall surface.

[0005] In view of the above problems, the present invention has an object to provide an electrical equipment storage box in which the roof can be attached after the box body is installed, even if the box is fixed to a wall surface. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides an electrical equipment storage box having a box body with an openable front and an equipment storage space for storing electrical equipment inside, and a roof body installed on the top plate of the box body, wherein the top plate allows the roof body placed on it to slide in the front-to-rear direction within a certain area and has a locking means for locking to the roof body placed on the top plate and slid rearward, while the roof body has a locking portion at a predetermined position on the top plate to be locked by the locking means, and the roof body moved rearward by sliding is locked to the box body at a predetermined position. With this configuration, the roof body can be connected to the box body at a predetermined position by sliding it backward, so that the roof body can be connected to the box body with a simple operation. In addition, since the roof body can be connected by sliding it from the front to the rear, the roof body can be attached even if the box body is fixed to a wall, and the installation location of the box body is not limited.

[0007] Another aspect of the present invention is characterized in that, in the above-mentioned configuration, the roof body has an abutment piece that abuts against the upper front end of the box body when it reaches a predetermined position by sliding rearward, and the abutment piece abutting against the box body can be screwed to the box body. According to this configuration, by screwing the abutment piece to the front surface of the box body, in combination with the action of the locking means, the roof body can be connected and fixed to the box body. Effect of the Invention

[0008] According to the present invention, the roof body can be connected to the box body by a simple operation because the roof body is engaged with the box body at a predetermined position by sliding backward. In addition, since the roof body can be connected by sliding from the front to the rear, the roof body can be attached even if the box body is fixed to a wall, and the installation location of the box body is not limited.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Figures 1 to 4 show an example of an electrical equipment storage box according to the present invention, where Figure 1 is a front view, Figure 2 is a perspective view with the roof body separated, Figure 3 is a cross-sectional view taken along line AA in Figure 1, and Figure 4 is an enlarged view of part C in Figure 3. The electrical equipment storage box 1 is composed of a box body 2 and a roof body 3 installed on the top of the box body 2. The box body 2 is composed of three sets of rectangular box bodies 2a with an open front and closing plates 2b that close the open front of the box bodies 2a, connected together in the horizontal direction. The roof body 3 is formed as a single plate-like body that entirely covers the three connected box bodies 2a. In this embodiment, three sets of boxes 2a are connected to form one electric device storage box 1, which is fixed to a wall surface of a building or the like.

[0011] As shown in Figure 2, a locking piece 22 is protruded from the top plate 21 of the box body 2 as a locking means for locking the roof body 3, and the locked portion (described later) 31 of the roof body 3 is locked to this locking piece 22 to position it, and a screw 6 as a connecting means is screwed in from the front side to fix the roof body 3. As shown in Fig. 3, an equipment storage space M for storing electrical equipment is formed inside the box body 2, and the open front side is closed by a closing plate 2b. Handles 23 are provided on the left and right sides of the closing plate 2b, and a locking bar 24 that expands and contracts by operating the handles 23 is provided vertically on the back side of the closing plate 2b. The expansion and contraction of the locking bar 24 locks and unlocks the closing plate 2b to the box body 2a. In addition, a mounting plate 27 for mounting equipment is provided inside the back plate 26 of the box body 2a. Fig. 4 shows the connection structure between the box body 2 and the roof body 3, in which the locking piece 22 provided on the top plate 21 of the box body 2 locks onto the locked part 31 of the roof body 3, and the front lower part of the roof body 3 is screwed to the front upper part of the box body 2 to connect the two. Reference numeral 6 denotes a screw for fastening the screw.

[0012] The connecting structure between the box body 2 and the roof body 3, and the procedure for attaching the roof body 3 will be described below. Fig. 5 is an enlarged view of part B in Fig. 2, showing the locking piece 22, and Fig. 6 is a partial perspective view of the roof body 3 as viewed from below, showing the locked part 31. As shown in Fig. 5, the locking piece 22 has a rising piece 22a arranged to stand from a fixing piece 22c welded to the top plate 21, and an insertion piece 22b formed by bending the tip of the rising piece 22a forward, and is formed in an L shape. As shown in FIG. 2, the locking piece 22 is formed on each box body 2a, and is provided at the center of each top plate 21 toward the rear.

[0013] Here, the structure of the roof body will be explained. The roof body 3 has a flat top surface 3a, and a frame body 3b is formed around the top surface 3a. The frame body 3b is formed by bending downward a plate body that is continuous with the top surface 3a, and is attached to the periphery of the top surface 3a. Of these, the front frame body 3b is formed to protrude forward from the top plate 21 of the box body 2a, forming an eave portion 32. The lower surfaces of the frame bodies 3b formed on the left and right sides form a sliding surface S that slides the roof body 3 in the front-rear direction on the top plate 21. Additionally, a beam 33 is installed horizontally on the underside of the roof body 3 in accordance with the position of the locking piece 22 on the top plate 21. Locked portions 31 are provided on the beam 33 at positions corresponding to the locking pieces 22 of each box body 2a. The locked portions 31 are horizontally elongated slit-shaped holes into which the insertion pieces 22b are inserted.

[0014] Furthermore, a belt-shaped abutment piece 34 that abuts against the front surface of the box body 2a is formed downward from the lower part of the eaves part 32, and a screw insertion hole 34a is drilled in an appropriate position for screwing to the box body 2a. Meanwhile, a through hole (not shown) through which the screw 6 is inserted is provided in the upper part of the front surface of the box body 2a corresponding to the screw insertion hole 34a, and a dome nut 35 (shown in FIG. 7) into which the screw 6 is inserted is attached to the inside of the box body 2a in alignment with the through hole.

[0015] FIG. 7 shows the procedure for attaching the roof body 3, where (a) shows the roof body 3 placed on the top plate 21, and (b) shows the locking pieces locked to the locked parts. 7, W indicates a wall surface of a building or the like, and the roof body 3 is attached with the box body 2 fixed to the wall surface W. For example, the back plate 26 of the box body 2 is fixed to the wall surface W with screws or the like (not shown). In addition, when the roof body 3 is attached, the closure plate 2b is removed. 7 shows the state where the closing plate 2b has been removed. Reference numeral 28 denotes a drip frame formed on the front surface of the box body 2a.

[0016] By fixing the box body 2 in this way, the roof body 3 can be attached in a stable state, and the roof body 3 is first placed in front of the fixed position as shown in Figure 7(a). After that, the left and right positions are aligned with the top surface of the box body 2, and then it is slid in the direction indicated by the arrow Q, that is, backwards. This sliding operation moves the roof body 3 and the locking pieces 22 lock into the locked portions 31. This position is the fixed position (predetermined position), and the locking action between the locking pieces 22 and the locked portions 31 prevents further sliding movement. At this time, the rear end of the roof body 3 is flush with the back plate 26 of the box body 2.

[0017] When the roof body 3 reaches the fixed position, the abutment piece 34 simultaneously abuts against the upper end of the front surface of the box body 2. This state is shown in Figure 7(b). Once the abutment piece 34 has reached the box body 2 in this way, the screw 6 is inserted into the screw insertion hole 34a provided in the abutment piece 34 and screwed to the box body 2. Once the screw is fastened, the installation of the roof body 3 is complete.

[0018] In this way, the roof body 3 is engaged with the box body 2 at a predetermined position by sliding backward, so that the roof body 3 can be connected to the box body 2 with a simple operation. In addition, since the roof body 3 can be connected by sliding from the front to the rear, the roof body 3 can be attached even when the box body 2 is fixed to the wall surface W, and the installation location of the box body 2 is not limited. Furthermore, by connecting the abutment piece 34 to the box body 2 with the screw 6, the roof body 3 is connected and fixed to the box body 2 in conjunction with the action of the locking piece 22.

[0019] Although the electric device storage box 1 in the above embodiment is shown as being composed of three box bodies 2a, the electric device storage box 1 may be composed of only one box body 2a. In addition, although a form in which it is attached to a wall surface W has been described, the above-mentioned mounting structure of the roof body 3 can also be applied to an electrical equipment storage box 1 that is installed freestanding, and the top surface of the roof body 3 does not need to be flat. Furthermore, the shapes of the locking piece 22 and the locked portion 31 are not limited to the above shapes, and may be reversed. That is, the locking piece 22 may be a hole-shaped locking means, and the locked portion 31 may be inserted into the locking means to be locked. Furthermore, a guide for guiding the sliding of the roof body 3 in the front-rear direction may be provided on the top plate 21, thereby eliminating the need for left-right positioning operations.
