[0002] The building electrical distribution box is a key device for distributing electric energy in the power system. It has a compact structure and diverse functions. Inside the distribution box, components such as switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment are usually integrated. These components are carefully assembled in a closed or semi-closed metal cabinet to form a low-voltage power distribution device. The structural design of the distribution box aims to facilitate management and maintenance while ensuring the safety and reliability of the circuit. Its shell is made of a strong metal material with a good protection level, which can effectively prevent external factors (such as dust, moisture, small animals, etc.) from eroding the internal equipment.

The distribution box unit includes a main frame 1. A door panel 2 is rotatably connected to the left side of the front surface of the main frame 1 through a hinge. An instrument 3 is installed on the door panel 2. Electrical components 4 are installed inside the main frame 1. Positioning grooves 5 are opened at the four corners of the upper surface of the main frame 1. A positioning post 6 corresponding to the positioning groove 5 is fixedly connected to the lower surface of the main frame 1. A rounded corner is opened at the bottom end of the positioning post 6.

[0025] As Figure 1 and Figure 5 shown, in this embodiment, the driving component 9 includes a worm 901 rotatably connected to the front of the fixed box 8. A hexagonal head 902 is fixedly connected to the front of the worm 901. The other end of the worm 901 is located inside the fixed box 8 and is meshed with a worm wheel 903. The middle of the disc 10 is fixedly connected with a rotating shaft 904. The upper and lower ends of the rotating shaft 904 are rotatably connected to the upper and lower inner walls of the fixed box 8 through bearings. The worm wheel 903 is fixedly connected to the outer surface of the rotating shaft 904; the positioning component 12 includes positioning rods 1201 slidably inserted into the left and right sides of the fixed box 8. The end of the positioning rod 1201 located outside the fixed box 8 is provided with a rounded corner.

The top end of the rotating shaft 904 is located outside the fixed box 8 and is provided with a connecting groove 1604 corresponding to the connecting block 1603. The outer surface of the rotating rod 1602 located inside the second mounting box 1601 is fixedly connected to a second gear 1605. The second gear 1605 is meshed with a second rack 1606. The left and right sides of the second rack 1606 penetrate through the left and right sides of the second mounting box 1601.

The connection sleeve 1401 has the same thickness as the fixed box 8. After stacking the distribution box units together, the upper threading hole 13 and the lower threading hole 14 are communicated, so there is no need to separately drill holes in the distribution box units, which facilitates connecting the electrical components 4 in the upper and lower distribution box units together with wires and makes the use more convenient.

[0033] A distribution box assembly method includes the following steps: Step 1: Stack the distribution box units together. At this time, the positioning posts 6 on the upper side will be inserted into the positioning grooves 5 on the lower side, and the connection sleeve 1401 contacts the main frame 1 on the lower side.

During the rotation of the disc 10, the positioning rod 1201 is driven to extend outward through the inclined hole 11 and the slider 1202 and inserted into the through hole 1203 on the positioning post 6. Step 3: And during the rotation of the rotating shaft 904, it can drive the first gear 1502 to rotate. During the rotation of the first gear 1502, it can drive the first baffle 1504 to open the upper threading hole 13 in cooperation with the first rack 1503. At the same time, during the rotation of the rotating shaft 904, it can drive the rotating rod 1602 and the second gear 1605 to rotate through the connecting block 1603. During the rotation of the second gear 1605, it can drive the second baffle 1607 to open the lower threading hole 14, completing the assembly of the distribution box unit.

During the rotation of the disc (10), the positioning rod (1201) is driven to extend outward through the inclined hole (11) and the slider (1202) and is inserted into the through hole (1203) on the positioning post (6). Step 3. During the rotation of the rotating shaft 904, it can drive the first gear (1502) to rotate. During the rotation of the first gear (1502), it can cooperate with the first rack (1503) to drive the first baffle (1504) to open the upper wire threading hole (13). At the same time, during the rotation of the rotating shaft (904), it can drive the rotating rod (1602) and the second gear (1602) to rotate through the connecting block (1603). During the rotation of the second gear (1602), it can cooperate with the second rack (1606) to drive the second baffle (1504) to open the lower wire threading hole (14), thus completing the assembly of the distribution box unit.
