[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a low-voltage distribution box with a bus duct, comprising an L-shaped plate 1, a side plate 8 is arranged on the L-shaped plate 1, and an observation window 2 is arranged on the L-shaped plate 1. Because the observation window 2 is provided, the situation inside the L-shaped plate 1 can be observed through the observation window 2. When the internal line is damaged, it can be discovered and repaired in time to prevent safety accidents.

[0020] The L-shaped plate 1 and the side plate 8 are both fixedly connected with vertical shafts 3, and the two vertical shafts 3 are rotatably connected with fixed plates 9, and the fixed plates 9 are fixedly connected with two fixed blocks 13, and a tool box 12 is provided on the side where the two fixed blocks 13 are close to each other. Because the tool box 12 is provided, when it is necessary to maintain the internal components of the L-shaped plate 1, the personnel can directly take tools from the tool box 12 to improve the maintenance efficiency. A screw 14 is threadedly connected to one of the fixed blocks 13, and a nut 15 is fixedly connected to one end of the screw 14. Because a number of grooves are provided on the nut 15, friction is increased, which makes it convenient for the staff to turn the nut 15.

[0021] A fourth bevel gear 20 is fixedly connected to one end of the vertical rotating shaft 3, a third bevel gear 19 is meshed on the fourth bevel gear 20, a transverse rotating shaft 4 is fixedly connected to the two third bevel gears 19, a second bevel gear 18 is fixedly connected to the transverse rotating shaft 4, a first bevel gear 17 is meshed on the second bevel gear 18, a motor 6 is fixedly connected to the first bevel gear 17, a connecting plate 5 is fixedly connected to one side of the motor 6, the connecting plate 5 is fixedly connected to the back of the fixing plate 9, and a top plate 7 is fixedly connected to the transverse rotating shaft 4.

[0022] A U-shaped plate 10 is fixedly connected to one side of the fixing plate 9, and a plurality of bus duct bodies 11 are arranged on the U-shaped plate 10. A plurality of heat dissipation holes 16 are opened on the side plate 8 and the L-shaped plate 1. Because of the heat dissipation holes 16, when the components in the L-shaped plate 1 are working, the heat is dissipated through the heat dissipation holes 16 to avoid damage to the components due to excessive temperature.

[0023] The working principle of the utility model is:

[0024] When it is necessary to inspect the inside of the L-shaped plate 1, the start motor 6 drives the first bevel gear 17, the second bevel gear 18 and the horizontal shaft 4 to rotate, and the horizontal shaft 4 drives the third bevel gear 19, the fourth bevel gear 20, the vertical shaft 3, the side plate 8, the top plate 7 and the L-shaped plate 1 to rotate synchronously, and the personnel can inspect the inside of the L-shaped plate 1 at this time;

[0025] The staff places the tools inside the tool box 12, and can take the tools from the tool box 12 when maintenance is needed. When the tool box 12 needs to be removed from the fixing plate 9 for cleaning, the nut 15 is twisted to loosen the tool box 12, and the tool box 12 can be disassembled and the staff can clean the inside thereof.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
