Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinet equipment, in particular to a power distribution cabinet which is convenient for maintenance. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box), which is the final equipment of the power distribution system. When the existing distribution cabinet is in use, the line is usually connected to the fixed frame fixed inside the distribution cabinet. By setting a bracket that is easy to move horizontally on the inner wall of the distribution cabinet, when an electrical fault occurs, the horizontal bracket is controlled to move, and the fixed frame with the horizontal bracket is driven to move inside the cabinet of the distribution cabinet to complete the circuit maintenance of the terminal block connection end inside the distribution cabinet. However, because the overall structure of the horizontal bracket moving plate is relatively bloated, the size of the distribution cabinet becomes larger, which is not convenient for installation in stairwells or hidden doors inside walls, reducing the practicality of the device.

[0003] After searching, for example (authorization announcement number CN219477327U) a power distribution cabinet that is easy to maintain, including a cabinet body and a distribution board arranged in the cabinet body, a vertical bidirectional screw is rotatably connected in the cabinet body, the upper and lower parts of the bidirectional screw are threadedly connected with screw sleeves, and the two screw sleeves are fixedly connected with transverse fixing rods, both ends of the transverse fixing rods are rotatably connected with connecting rods, one end of the connecting rod is rotatably connected to the distribution board, and a device for driving the bidirectional screw to rotate is also provided on the cabinet body. The stamp paper solves the problem that the existing equipment has a narrow cabinet space and is inconvenient to operate when performing circuit maintenance. However, when the device is in use, a bracket that can be moved laterally is set on the inner wall of the cabinet body. The setting of the transverse bracket makes the size of the distribution cabinet larger than the conventional size, making it inconvenient to fix in narrow places such as stairwells, reducing the practicality of the device.
