JP, 2016-207865, A

The configuration disclosed in Patent Document 1 described above, that is, the configuration in which a positioning member that abuts and positions the bottom frame of the box-shaped frame placed on the lower side of the box-shaped frame is provided, for example, in the front-back direction. The positioning could be done accurately. However, in that case, since the positioning in the left-right direction relies on visual observation, it is necessary to further align the holes through which the bolts are inserted.

Therefore, in view of the above problems, the present invention provides an electrical device storage having a structure capable of easily aligning the bolt insertion holes between the box-shaped frames when they are vertically stacked. It is intended to provide a board.

In order to solve the above-mentioned problem, the invention of claim 1 is formed by vertically stacking a plurality of box-shaped frame bodies that are formed by connecting rod-shaped frames, and the stacked frame bodies are connected by bolts. In the electric equipment storage board, the alignment parts for aligning the bolt insertion holes are provided on the contact surfaces of the rod-shaped frames of the two stacked frames, and the alignment part of one frame is The protrusion is a protrusion, and the alignment portion of the other frame has an accommodating portion that accommodates the protrusion, and a guide groove that is linearly formed from the accommodating portion and that guides the protrusion to the accommodating portion. Characterize.
According to this configuration, if the protrusions are aligned with the guide grooves in a state where the box-shaped frame bodies are stacked, the protrusions eventually align with the accommodating portion by the subsequent sliding operation, and the alignment is completed. Therefore, the bolt insertion holes can be smoothly aligned with each other.

According to a second aspect of the present invention, in the structure according to the first aspect, the protrusion and the housing portion are formed so as to form a pair at left-right or front-rear symmetrical positions of the frame body, and similarly, guide grooves formed at symmetrical positions are formed. Are formed in parallel with each other.
According to this structure, the protrusions at two locations may be housed in the housing portion, and the frame bodies can be aligned with each other by a simple operation.

According to a third aspect of the present invention, in the configuration according to the first or second aspect, the accommodation portion is a recess or a hole formed in the same outer shape as the protrusion.
According to this configuration, since the accommodating portion has the same outer shape as the protrusion, the protrusion that has entered the accommodating portion is entirely accommodated, and there is no rattling, so that the alignment can be performed with high accuracy.

According to a fourth aspect of the present invention, in the structure according to any one of the first to third aspects, the guide groove is a notch or a recess formed with a constant width narrower than the width of the protrusion.
According to this configuration, even if the protrusion enters the guide groove, the whole does not enter. Therefore, it is possible to recognize when a protrusion is formed in the guide groove from the state of the gap between the overlapping frame bodies, recognize that it is necessary to linearly move after entering the guide groove, and it is easy to align the position.

According to the present invention, if the projections are aligned with the guide grooves in a state where the box-shaped frame bodies are stacked, the projections eventually align with the accommodating portion by the subsequent sliding operation, and the alignment is completed. Therefore, the bolt insertion holes can be smoothly aligned with each other.

It is an enlarged view of part A. It is a section explanatory view of an alignment part. It is explanatory drawing which shows the other example of the alignment part.

Hereinafter, embodiments that embody the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of an electric device storage board according to the present invention, showing a state in which the electric device is not assembled.
The electric device storage board shown in FIG. 1 is formed by stacking two box-shaped frame bodies 1 (1a, 1b) on top of each other, and bolted together for connection. Further, side plates and the like are attached and closed as necessary.
The frame body 1 is formed by connecting a rod-shaped frame 10 made of a metal having a U-shaped cross section by welding or the like, and is erected between a rectangular bottom frame 11 and a top frame 12 and four corners of both. It has four columns 13. The bottom surface of the bottom frame 11 and the top surface of the top frame 12 have flat surfaces, and are formed so that the side surfaces of the rod-shaped frame 10 are in close contact with each other when the frame bodies 1 are stacked.

FIG. 2 shows the upper part of the first frame 1a arranged on the lower side, and a projection 15 which constitutes one of alignment parts for aligning the bolt insertion holes (not shown) is formed on the top surface. There is. The protrusions 15 are formed in a hemispherical shape, and are formed on the left and right sides of the top frame 12 at symmetrical positions.

FIG. 3 is an enlarged view of part A, showing the alignment part. As shown in FIG. 3, the other of the alignment portions is formed on the bottom surface of the bottom frame 11 of the second frame body 1 b arranged on the upper side, and the accommodation hole 16 for accommodating the projection 15 and the accommodation hole 16 are formed. A guide groove 17 for guiding the protrusion 15 is formed. The accommodation hole 18 and the guide groove 17 are formed at symmetrical positions on both left and right sides of the bottom frame 11 of the second frame body 1b.

The accommodation hole 16 is formed at a predetermined position corresponding to the position of the protrusion 15, and when the left and right protrusions 15 are aligned with the respective accommodation holes 16, the bolt insertion holes are also aligned with each other.
The accommodating hole 16 is a circular hole formed with the same diameter as the protrusion 15, and is formed so as to accommodate the entire protrusion 15 when matched.

The guide groove 17 is formed with a width smaller than the diameter of the protrusion 15, and is linearly formed with a constant width from the front end of the accommodation hole 16 toward the front. For example, it is formed with a width of about ½ of the diameter of the protrusion 15.

The box-shaped frame bodies thus formed are connected as follows. First, the first frame 1a having the projection 15 is arranged below, and the second frame 1b having the accommodation hole 16 is placed thereon. At this time, the projection 15 is arranged on the top surface (the frame provided with the projection 15 is arranged as the top frame 12), and the accommodation hole 16 is arranged on the bottom surface (the frame provided with the accommodation hole 16 is arranged as the bottom frame 11). Further, the orientations are aligned so that these alignment parts are arranged on the left and right. At this time, the second frame 1b may be placed slightly displaced rearward, so that the positioning operation becomes easy.
After placing, match the left and right directions. By doing so, when the guide groove 17 and the projection 15 are engaged with each other in the state where a large gap is initially generated between the two, the gap is reduced.
FIG. 4 is a cross-sectional explanatory view showing this state, that is, the state in which the projection 15 is engaged with the guide groove 17 and the gap D between the first frame body 1a and the second frame body 1b is reduced. The projection 15 is shown here as being formed by attaching a rivet having a hemispherical head to the top frame 12.

When the gap D becomes smaller, the projection 15 will eventually enter the accommodation hole 16 by shifting the second frame 1b forward, and the gap will disappear. If the state without this gap occurs on the left and right, the alignment is completed. As a result, the bolt insertion holes match each other and the bolts can be smoothly inserted, and the upper and lower frame bodies 1 can be connected to each other.

Thus, if the projections 15 are aligned with the guide grooves 17 in the state where the frame bodies 1 are stacked, the projections 15 are eventually aligned with the accommodation holes 16 by the subsequent sliding operation, and the alignment is completed. Therefore, the bolt insertion holes can be smoothly aligned with each other.
Further, the protrusions 15 at the two right and left positions may be housed in the housing holes 16, and the frame bodies can be aligned with each other by a simple operation.
Further, since the accommodation hole 16 has the same outer shape as the protrusion 15, the entire protrusion 15 that has entered the accommodation hole 16 is accommodated and no gap is generated, so that there is no rattling and the positioning can be performed reliably.
In addition, since the guide groove 17 is formed with a constant width narrower than the width of the protrusion 15, even if the protrusion 15 enters the guide groove 17, the entire space does not enter the extent that the gap becomes narrow, and the space between the stacked frame bodies 1 does not occur. If the projection 15 enters the guide groove 17 from the state of the gap, it can be grasped. After entering the guide groove 17, it is possible to recognize that it is only necessary to move in a straight line, and it is easy to align the position.
In addition, in the above-described embodiment, the alignment portions are arranged on the left and right sides of the frame body 1, but they may be arranged on the front and rear sides.

FIG. 5 shows another shape of the alignment section. FIG. 5A shows a configuration in which the accommodation holes 16 are provided at symmetrical positions in the front-rear direction and both are connected by the guide groove 17. There is no change in the protrusion 15 formed on the first frame 1a. If formed in this way, there is no restriction in the front-rear direction on the second frame 1b, and there is no need to worry about the front-back when assembling the device in advance.
FIG. 5B shows a configuration in which the accommodation hole 16 is arranged in the center of the side and the guide groove 17 is provided in the front and rear thereof. The corresponding protrusion 15 is also provided at the center of the side. If the guide groove 17 is provided before and after the accommodation hole 16 in this way, the position of the second frame 1b to be initially placed is not limited, and the position of the protrusion 15 does not change even when the front and rear is inverted. There are no restrictions on the direction.
FIG. 5C shows a configuration in which the guide groove 17 is not formed to have a constant width but is formed to have a taper and is gradually narrowed from the accommodation hole 16. Although the projection 15 is formed at the center of the side, it may be at the end shown in FIG. In this case, if the protrusion 15 approaches the accommodation hole 16, the gap becomes smaller, and thus the sliding direction can be easily grasped.
Although the guide groove 17 is formed with a constant width in FIG. 5D, the guide groove 17 is formed with two kinds of widths, and the portion close to the accommodation hole 16 is formed wide. Even if the guide groove 17 is formed in this way, the same effect as that of the shape of FIG. 5C is obtained, and the sliding direction can be easily grasped.

In the above embodiment, the protrusion 15 is formed by attaching a screw, but it may be provided in another form, for example, by press molding, or may not have a hemispherical shape. Further, although the accommodation hole 16 and the guide groove 17 are formed by forming a hole or a groove in the rod-shaped frame 10, they may be formed in a concave shape without being bored. Furthermore, although the projection 15 is provided on the first frame 1a and the accommodation hole 16 is provided on the second frame 1b, they may be reversed.
Further, although the electric device storage board formed in two steps is shown, it may be formed in three steps, and the above-mentioned alignment portion may be provided on each connection surface, so that connection by bolts can be smoothly performed. ..
