The massive parameters on the distribution box data generally constitute a low-voltage forest according to electrical wiring, requiring the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be assembled in a closed or semi-enclosed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches.

[0003] After searching, it is found that a distribution box with a rail structure is disclosed in Chinese patent literature [Application number: 202321146596.7; Publication number: CN 219874661 U]. A distribution box with a rail structure includes a box body, positioning plates are fixedly installed at equal distances on both sides of the box body, a limiting groove is provided on the top surface of the positioning plate, positioning threaded holes are provided on both sides of the limiting groove, a positioning screw is rotatably connected in the positioning threaded hole, a clamping plate is fixedly installed at the end of the positioning screw away from the positioning threaded hole, and a fixed block is slidably connected in the limiting groove. The utility model discloses a distribution box with a rail structure, the fixed block can be moved in the limiting groove, so that the position of the rail can meet the requirements, and after the positioning screw is rotated, the two clamping plates in a single limiting groove can clamp the fixed block, so that the position of the fixed block is fixed, and then the position of the rail is fixed. At this time, personnel can fix the corresponding electrical components on the rail to complete the installation of the electrical components, which is suitable for being widely promoted and used.

[0004] Although this patent can fix the corresponding electrical components on the rail, the rail will wear and deform after long-term use, which may also cause the rail to get stuck. At this time, the rail needs to be replaced. This patent requires manual rotation of the positioning screw to fix the rail, but the positioning screw is located in the limit groove, which is hidden and has a small space, making it difficult for personnel to operate, affecting the efficiency of normal replacement of the rail and being relatively cumbersome.
