Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention connects the first installation hole on the distribution box The second installation holes on the copper bar are aligned with each other, and the operation is convenient; (2) After the first installation hole on the distribution box is aligned with the second installation hole on the copper bar, the U-shaped clip is removed, and the U-shaped The clip can be reused; (3) The thickness of the U-shaped clip is 0.5mm~1mm, and it is made of plastic, which can penetrate into the "dead corner" of the distribution box where some construction workers' hands are difficult to reach, which is very convenient; (4) This The invention has simple structure and is convenient for popularization.

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Description of drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a schematic diagram of the installation structure of the copper bars of the distribution box according to the embodiment of the present invention.

In the figure: 1-U-shaped clip, 2-left rib arm, 3-iron block, 4-right rib arm, 5-magnet column, 6-distribution box, 61-first installation hole, 7-copper row, 71 -Second mounting hole, 8-spring, 9-bolt.

Detailed ways

As shown in Figures 1 and 2, a new installation and alignment device for copper bars 7 of a distribution box includes a U-shaped clip 1, and an iron block 3 is inlaid on the inner side of the end of the left tendon arm 2 of the U-shaped clip 1. The inside of the end of the right muscle arm 4 of the U-shaped clip 1 is correspondingly inlaid with a magnet column 5, and the magnet column 5 is matched with the first installation hole 61 on the distribution box 6 and the second installation hole 71 on the copper bar 7, A spring 8 for clamping is fixedly connected between the left muscle arm 2 and the right muscle arm 4 .

In this embodiment, the front end of the magnet column 5 is hemispherical, which is convenient for the magnet column 5 to enter the first installation hole 61 and the second installation hole 71; The thickness of the clip 1 can be appropriately increased or decreased so as to be suitable for different environments; the U-shaped clip 1 is made of plastic, or other materials with certain elasticity, toughness, hardness, and non-magnetic properties, such as bamboo chips.

A method for aligning the installation and alignment device of a new type of distribution box 6 copper bars 7 is carried out according to the following steps:

(1) Move the copper bar 7 to the vicinity of the distribution box 6, roughly align the second installation hole 71 with the first installation hole 61, open the U-shaped clip 1, and inlay the U-shaped clip 1 with the right rib arm of the iron block 3 4 protruding into the back of the distribution box 6, the iron block 3 covers the first installation hole 61, the left arm 2 of the U-shaped clip 1 embedded with the magnet column 5 is covered on the second installation hole 71 of the copper bar 7, and the The magnet column 5 extends into the second installation hole 71, and at this time, due to the mutual attraction between the magnet column 5 and the iron block 3, the first installation hole 61 of the distribution box 6 is aligned with the second installation hole 71 on the copper bar 7;
