[0002] The distribution cabinet is a very important electrical device in the power system and is used for receiving, distributing, and controlling electric energy. In the power system, the distribution cabinet plays a crucial role. It is not only the hub of power transmission but also the key facility to ensure the safe and stable operation of electricity. Currently, most distribution cabinets are equipped with lighting devices to facilitate the maintenance and installation of circuits by staff.

[0003] According to the search, the Chinese patent document, publication number: CN208368995U, discloses a distribution cabinet with a lighting function. The distribution cabinet installs the light strip in the light strip groove arranged around the cabinet door, so that the light emitted by the light strip directly shines into the interior of the distribution cabinet, avoiding directly shining into the eyes of the staff and causing dizziness to the staff. Moreover, the light strip is arranged around the cabinet door, making the light in the distribution cabinet uniform without dead spots of illumination; in addition, the light strip is directly powered by a storage battery, and when a circuit failure occurs in the distribution cabinet, the light strip can still work normally, facilitating the maintenance of the staff.

[0004] However, the above distribution cabinet still has certain defects in the actual application process: for example, when maintaining the distribution cabinet, it is necessary for the staff to grope for the switch of the light strip and then manually turn on the light strip, which brings inconvenience to the staff. In addition, there is also the problem that it is inconvenient to replace the light strip once it is damaged. Summary of the Utility Model

[0030] Specifically, the short rail 5 is connected to the inner top surface of the electric cabinet body 1 by screws, one end of the spring 9 abuts against the second lamp holder 6, and the other end of the spring 9 abuts against the fixing plate 10. The advantage is that if the lamp tube 7 is damaged, the second lamp holder 6 is moved to slide on the outer surface of the short rail 5, which will drive the sleeve rod 8 to compress the spring 9, so that one end of the lamp tube 7 is separated from the second lamp holder 6, and then it is convenient to pull the lamp tube 7 out of the first lamp holder 4. The overall structure is convenient for quickly disassembling the lamp tube 7, and then it is convenient to replace the new lamp tube 7.

[0031] Specifically, the outer surfaces of the fixing plate 10 and the second lamp holder 6 are connected to a connecting plate 17 through a rotating rod, and one end of the two connecting plates 17 is fixedly connected to a light-proof baffle 18. The advantage is that by setting the light-proof baffle 18 in front of the lamp tube 7, when the staff opens the cabinet door 2 to inspect the electrical components inside the electric cabinet body 1, the light emitted by the lamp tube 7 will not directly hit the eyes of the staff, thereby playing a role in preventing glare.
