By the way, if a packing is interposed between the draining portion and the back surface of the door with respect to a structure in which the draining portion and the back surface of the door are normally used in close contact with each other, the door cannot be closed. Further, if the packing is not attached to the structure in which the packing is interposed between the draining portion and the back surface of the door, a gap that cannot be overlooked is generated between the draining portion and the back surface of the door. Therefore, it is necessary to separately manufacture a box for storing electrical equipment in a form in which the box is used with the packing interposed therebetween and a box in which the box is used without the packing. For this reason, it is necessary to prepare a plurality of housings and doors having different sizes, resulting in high cost.

The inventor of this case tried to solve this problem by diligently examining this point. An object of the present invention is to provide a box for storing electrical equipment in which the distance between the circumference of the opening and the back surface of the door when the door is in the closed position can be adjusted.

A mode for carrying out the invention is shown below. The electric device storage box 1 of the present embodiment includes a housing 11 having an opening 12 and a door 13 for closing the opening 12. Further, it is provided with a first bearing portion 21 and a second bearing portion 22 capable of connecting the housing 11 and the door 13 by fitting the shaft 23. The rotation center of the door 13 when the shaft 23 is fitted to the second bearing portion 22 is different from the rotation center of the door 13 when the shaft 23 is fitted to the first bearing portion 21. Therefore, it is possible to provide the electric device storage box 1 in which the distance between the periphery of the opening 12 and the back surface of the door 13 when the door 13 is in the closed position can be adjusted.

As can be seen from FIG. 1, the electrical equipment storage box 1 of the present embodiment includes a housing 11, a door 13, and a roof 14. The housing 11 of the present embodiment includes a substrate 91 inside, and an electric device or the like is arranged on the substrate 91. As can be understood from FIG. 2, the housing 11 and the door 13 have connection portions 31 and 32, respectively, and the door 13 is connected by connecting the connection portions 31 and 32, respectively. It is rotatably attached to the housing 11. More specifically, the door 13 and the housing 11 are rotatably connected by fitting the shaft 23 into the first bearing portion 21 or the second bearing portion 22.

The housing 11 and the door 13 of the present embodiment are made of resin, and the connection portions 31 and 32 are integrally formed with the housing 11 and the door 13, but the housing 11 and the door 13 may be made of metal. Alternatively, a hinge formed separately may be attached to the housing 11 or the door 13.

The housing 11 and the door 13 are provided with a locking portion on a side surface portion opposite to the side surface portion on which the connecting portions 31 and 32 are provided. The electric device storage box 1 is locked by fitting the lock portion 82 on the door 13 side to the lock portion 81 on the housing 11 side. In the present embodiment, the roof 14 is provided on the upper part of the housing 11, but by doing so, the housing can be inserted between the housing 11 and the door 13 of the locked electric device storage box 1. It is possible to prevent water from entering the inside of the eleven.

By the way, the connection portion 31 of the housing 11 of the present embodiment is provided with a plurality of bearing portions. By providing a plurality of bearing portions in the connection portion 31 of the housing 11 in this way, the mounting position of the shaft 23 provided on the door 13 side can be changed. For example, when the shaft 23 is attached as shown in FIGS. 3 and 4, and when the shaft 23 is attached as shown in FIGS. 5 and 6, the attachment position of the shaft 23 is changed, so that the door 13 is rotated. The movement locus changes, and the positional relationship between the door 13 and the housing 11 when the door 13 is in the closed position changes. Therefore, it is possible to change the space between the housing 11 and the door 13 without preparing the housing 11 and the door 13 having different sizes.

In the present embodiment, the bearing portions are arranged so as to be arranged in the front-rear direction of the housing 11. With such a positional relationship, it is possible to cope with a change in the space between the housing 11 and the door 13 without complicating the structure. Here, the front bearing portion is referred to as the first bearing portion 21, and the rear bearing portion is referred to as the second bearing portion 22.

In the form shown in FIGS. 7 and 8, the bearing portion has a hole shape with a notch 25 partially provided, and the cylindrical shaft 23 is formed. In this case, the shaft 23 and the bearing portion can be combined by inserting the shaft 23 from the notch portion 25. It is preferable that the shaft 23 has a structure that does not easily come off from the bearing portion. For example, a recess is provided on the side surface of the columnar shaft 23 so that only the recess can pass through the notch 25. Therefore, if the door 13 can be removed from the housing 11 only when the door 13 is opened at a certain angle, the shaft 23 cannot be easily removed from the bearing portion. The structure may be such that the shaft 23 is inserted into the bearing portion by elastically deforming the bearing portion to increase the notch portion 25.

In the example shown in FIG. 7, the notch 25 of the first bearing portion 21 and the notch 25 of the second bearing 22 are provided in the same direction. Therefore, the moving direction when the shaft 23 is fitted into the bearing portion is the same. More specifically, the shaft 23 is moved in the left-right direction of the housing 11 regardless of which bearing portion the shaft 23 is fitted into. On the other hand, in the example shown in FIG. 8, the notch 25 of the first bearing 21 is provided so as to extend in the left-right direction of the housing 11, and the notch 25 of the second bearing 22 is a casing. It is provided so as to extend in the front-rear direction of the body 11. In this way, the direction in which the shaft 23 is moved changes depending on whether the shaft 23 is fitted into the first bearing portion 21 or the second bearing portion 22, so that it is easy to confirm the position when mounting the shaft 23. Can be.

In the present embodiment, the connection portion 31 on the housing 11 side is provided with a hole-shaped bearing portion, and the connection portion 32 on the door 13 side is provided with the shaft 23. However, the connection portion 31 on the housing 11 side is also a door. The connecting portion 32 on the 13 side may also have a hole shape, and a shaft 23 made of another member may be inserted into both holes to connect the connecting portions 32.

By the way, in the present embodiment, the mounting position of the shaft 23 can be changed, but the locking portion also corresponds to this. In the present embodiment, a plurality of locking portions are provided on the locking portion 81 on the housing 11 side that locks on the locking portion 82 on the door 13 side. More specifically, the one provided with the first locking portion 71 used when the first bearing portion 21 is used and the second locking portion 72 used when the second bearing portion 22 is used. The structure is such that the lock portion 81 on the housing 11 side is locked.

As for the structure of the locking portion 81 on the housing 11 side of the present embodiment, it is preferable that the first locking portion 71 and the second locking portion 72 are arranged side by side in the front-rear direction of the door 13. In the example shown in FIG. 9, the shape is such that the first locking portion 71 and the second locking portion 72 can be separated from each other as needed. When the first locking portion 71 is used, the first locking portion 71 is used. The second locking portion 72 is separated. The structure including a plurality of locking portions may be on the door 13 side instead of the housing 11 side.

In the present embodiment, when the shaft 23 is attached to the second bearing portion 22, the drainer 15 around the opening 12 of the housing 11 and the contact surface inside the door 13 come into contact with each other to form a housing. Prevents water from entering the inside of the body 11. Further, when the shaft 23 is attached to the first bearing portion 21, a gap is generated between the drainer 15 of the housing 11 and the contact surface of the door 13 even when the door 13 is in the closed position. .. However, by interposing the packing 6 in the gap generated between the housing 11 and the door 13, it is possible to prevent water from entering the housing 11, and the structure is such that the drainer 15 and the contact surface are in contact with each other. Can also improve waterproof performance. In the present embodiment, the packing 6 is attached to the door 13, but the position where the packing 6 is attached may be the drainer 15 of the housing 11 or the contact surface of the door 13.

Although the above description has focused on one embodiment, the present invention is not limited to the above embodiment and can be in various modes. For example, when the first locking portion is used, the second locking portion may be bent and used. Further, a shaft may be formed on the housing side and a plurality of bearing portions may be formed on the door side.

In the embodiment, the bearing portion is two so that one of the two rotation centers can be selected, but the bearing portion may be provided so that the rotation center can be selected from three or more.
