[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for integrally connecting a plurality of boxes for storing electric equipment.

[0002]

2. Description of the Related Art In general, when a relatively heavy box is installed, the box is divided into a plurality of pieces so that the box can be easily transported to a site, and the box is assembled and connected together. Conventionally, for example, a technique shown in FIG. 5 is known as this type of box connecting device. FIG. 5 is a perspective view showing a conventional box connection structure, and FIG. 6 is an explanatory view of the connection device in FIG. 5. Connection holes 23, 23 are formed in connection surfaces 22, 22 of a pair of boxes 21 which are joined together. A connecting rod 25 having nut portions 24 at both ends is formed between the connecting holes 23,
By inserting and tightening bolts 26, 26 through 3, 23 and connecting rod 25, each box 21 is connected and fixed to each other.

[0003]

However, according to the above conventional example, not only the alignment of the connection hole 23 but also the connection surface 22 of one of the boxes 21 if the floor is not kept horizontal during the connection work. Since the bolt 26 is tightened while being aligned with the connection surface 22 of the other box 21, a great amount of force is required. In addition, when the bolt 26 is tightened, the bolt 26 is often tightened diagonally. There is a drawback that the operation is very difficult, for example.

[0004]

In order to solve the above-mentioned problems, a connecting device for a box for storing electric equipment according to the present invention includes a fixing device for fixing a connecting surface of one box and a box for the other. A receiving member having a notch for fixing a connecting surface of a body, an adjusting metal member having an elongated hole so that the fixing member and the receiving member can be slidably adjusted, and a length of the connecting device by the elongated hole of the adjusting metal member. Tighten the adjusting screw to adjust and the holder, and connect the box
And a connection fixing screw for fixing.

[0005]

According to the connecting device for a box for storing electric equipment of the present invention, the connecting surface of one of the boxes is not required for the box body, such as notching or drilling, and a large amount of force is required. Adjusting the adjusting member of the connecting member to a position where the receiving member and the locking member of the connecting fixing screw are hooked on the connecting surface of the other box body,
By tightening the connection fixing screw of the receiver, the respective boxes are connected and fixed to each other.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an embodiment of the present invention; FIG.

FIG. 1 is an explanatory view of a connecting device for a box for storing electric equipment according to the present invention, and FIG. 2 is an exploded view of the connecting device in FIG. 1 for connecting adjacent boxes 1 for storing electric equipment. A fixing device 3 for fixing the connecting surface 2 of the one box 1 and a receiving device 5 having a notch 4 for fixing the connecting surface 2 of the other box 1. , Its fixture 3
Metal fitting 7 having a long hole 6 so as to allow slide adjustment of the receiving tool 5, an adjusting screw 9 for adjusting the length of the connecting device 8 by the long hole 6 of the adjusting metal fitting 7, and a box body for tightening the receiving tool 5. 1 and a connection fixing screw 10 for connecting and fixing.

FIG. 3 and FIG. 4 are views for explaining the installation of the connecting device of the box for storing electric equipment according to the present invention. ,
If there is a gap between the two, when the boxes 1 are connected and fixed to each other, the length of the connecting device 8 is adjusted in advance so that one connecting surface 2 fits into the notch 4 of the receiving member 5. 7, the fixture 3 is fixed to the connection surface 2 of one box 1 and the connection fixing screw 10 of the receiver 5 is fixed to the connection surface 2 of the other box 1.

By tightening the connection fixing screw 10 of the hooked connection device 8, the gap between the connection surfaces 2, 2 is filled, and one of the connection surfaces 2 is fitted into the notch 4 of the receiving member 5, and 1 are connected and fixed to each other.

The shapes and mounting directions of the fixing device 3 and the receiving device 5 of the connecting device 8 and the number of the boxes 1 to be connected are not limited to the above-described embodiment, but the purpose and the purpose of the present invention. It can be changed as appropriate without departing from the scope.

[0011]

As described above in detail, the connecting device for a box for storing electric equipment according to the present invention includes a fixing device for fixing a connecting surface of one box and a connecting surface of the other box. Receiving member having a notch for fixing the fixing device, an adjusting metal member having a long hole so that the fixing member and the receiving member can be slidably adjusted, and an adjusting screw for adjusting the length of the connecting device by the long hole of the adjusting metal member. When,
Since each of the boxes is constituted by a connection fixing screw for tightening the receiving member and connecting and fixing the box body, each box can be formed only by tightening the connection fixing screw of the receiving member without requiring secondary processing and a large amount of force on the box body. It has an excellent effect that the bodies are connected and fixed to each other.
