[0025] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0026] A distribution box convenient for maintenance, including a box base 1, a back plate 2 is fixedly connected to the top back side of the box base 1, a wire shaft 3 is rotatably connected to the center of the front surface of the back plate 2, a movable block 4 is threadedly connected to the surface of the wire shaft 3, a connecting rod 5 is fixedly connected to the top of the movable block 4, the top of the connecting rod 5 is fixedly connected to the inner wall top of the box cover 6, the box cover 6 is slidably snap-connected to the box base 1 and the back plate 2 respectively, a driven wheel 7 is fixedly connected to the bottom of the wire shaft 3, the surface of the driven wheel 7 is drivingly connected to a driving wheel 9 through a synchronous belt 8, the center of the driving wheel 9 is fixedly connected to the output shaft of a driving motor 10, the driving motor 10 is embedded and fixedly connected to the top of the box base 1. By using the driving motor to drive the driving wheel to rotate, the driving wheel drives the driven wheel to rotate through the synchronous belt, the driven wheel drives the wire shaft to rotate, the wire shaft drives the movable block to move up and down, the movable block drives the connecting rod to move up and down, and the connecting rod drives the box cover to slide up and down along the back plate. When the driving motor rotates forward, the movable block moves up, and the box cover is separated and opened from the box cover; when the driving motor rotates reversely, the movable block moves down, and the box cover is snap-connected and closed with the box base; through the three-sided opening and closing design of the box cover and the box base, the components and wire harness racks installed on the back plate connection frame can be fully exposed during maintenance to increase the maintenance space and facilitate maintenance; on the front surface of the back plate 2 and on both sides of the wire shaft 3, connection frames 11 are fixedly connected at equal intervals for fixedly installing the electrical components inside the distribution box; the outer ends of the connection frames 11 are all rotatably connected with wire harness racks 12 for correspondingly and effectively clamping and binding the external connection cables of the electrical components inside the distribution box, which is convenient for sectional management inside the distribution box and at the same time convenient for quickly finding the cables, and is convenient for quickly confirming, disassembling and replacing abnormal cables during maintenance to improve the maintenance efficiency.
