A second slot is provided at both ends of the inner side of each side plate. A third slot is provided on both sides of the top of the bottom plate, and the third slot is correspondingly provided with the second slot. The sides and bottom of the first electrical mounting plate are respectively engaged with the sides and bottom of the second electrical mounting plate and installed inside the second slot and the third slot. Clamping plates are fixedly installed on both sides of the bottom of the top cover, and the inner walls of the two clamping plates are tightly abutting against the outer walls of the top of the two side plates.

[0007] Using the above technical solution, the electrical mounting plate is snapped into the inside of the housing, which is convenient for disassembly and installation, maintenance and repair. The top cover is removable, making it easy to remove the electrical mounting plate for repair.

[0008] The top cover has first slots on both sides of its bottom. The top of the first electrical mounting plate and the top of the second electrical mounting plate are respectively engaged and installed inside the two first slots. Rubber pads are adhered to the inner walls of the first slot, the second slot, and the third slot.

[0009] The above technical solution uses a soft rubber pad that provides cushioning and protection, preventing damage to the internal electrical mounting plate when the distribution box is bumped or moved.

[0010] Both ends of the top of the side plate are provided with threaded through holes, and both ends of the clamping plate near the side plate are provided with threaded holes. The threaded through holes and the threaded holes are provided in a corresponding manner, and screws are installed inside them in sequence.

[0011] Using the above technical solution, the two clamping plates are snapped together and installed on the outer side of the top of the two side plates, and the top cover is tightly connected to the outer shell.

[0012] A strip plate is fixedly installed in the middle of the inner side of each of the two side plates. Three fixed brackets are evenly fixedly installed between the two strip plates. Two connectors are arranged in sequence on one side of each fixed bracket. A fixed plate is fixedly installed on the side of each connector away from the fixed bracket. The side of the fixed plate away from the connector is in close contact with the back of the first electrical mounting plate.

[0013] With the above technical solution, the fixing plate is tightly abutted against the back of the first electrical mounting plate, providing support and reinforcement.

[0014] The two ends of the back of the fixed bracket are respectively tightly abutted against one side of the two strips, and the middle of both sides is provided with a first mounting hole. The two ends of the connector are respectively fixedly installed with a first connecting plate and a second connecting plate. The second connecting plate is snapped onto the front of the fixed bracket, and the two sides of the second connecting plate are fixedly connected to the fixed bracket by bolts.

[0015] The above technical solution has threaded through holes at both ends of the second connecting plate, which facilitates the bolts to pass through and connect to the fixed bracket for fixing.

[0016] The fixing plate has several second mounting holes evenly distributed in the middle. The two first connecting plates are respectively tightly abutted against the two ends of the back of the fixing plate and are fixedly connected by bolts.

[0017] The above technical solution has a threaded hole in the middle of the first connecting plate, which corresponds to the position of the second mounting hole.

[0018] The side panel has handles at all four corners, and the inner corners of the handles are rounded and chamfered, with protective sleeves fixedly installed inside. The bottom of the base plate has feet fixedly installed at all four corners, with floor mats glued to the bottom of the feet.

[0019] The above technical solution features a handle for easy lifting and moving of the distribution box, support legs for support, and a floor mat to prevent slipping.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The electrical mounting plate of this utility model is inserted into the housing through the second slots on both sides. The top cover presses on the top of the housing and the electrical mounting plate, which plays a fixing role and ensures that the electrical mounting plate is firmly installed. The fixing bracket and fixing plate are located on the back of the first electrical mounting plate, which plays a supporting and fixing role. This utility model can be quickly installed and disassembled, and is convenient for maintenance and repair. Attached Figure Description
