[0020] Reference Figures 1-4 , set up distribution box body 1, place multiple lines in distribution box body 1, distribution box body 1 is rotationally connected with sealing door 11, sealing door 11 can seal and lock the inside of distribution box body 1, distribution box body 1 is internally provided with several distribution parts 12, distribution part 12 includes circuit line plate 121 and the partition plate 122 that is set in the peripheral of circuit line plate 121, circuit line is arranged on circuit line plate 121, circuit line plate 121 uses high-temperature resistant material, prevents burning, the peripheral of circuit line plate 121 is provided with partition plate 122, partition plate 122 is made of fireproof high-temperature resistant material, can effectively prevent the spread of fire when fire, partition plate 122 is surrounded and forms partition area 123, can be isolated to the fire in partition area 123.

[0021] Reference Figures 1-4A flexible fireproof cover 2 is rotatably connected to the partition plate 122. The surface of the flexible fireproof cover 2 is made of flexible composite material, which can isolate oxygen and is flame-retardant. The flexible fireproof cover 2 covers the partition area 123. A drive assembly 21 is provided on one side of the flexible fireproof cover 2. The drive assembly 21 includes two drive rods 211. The two ends of the flexible fireproof cover 2 are respectively fixedly connected to the two drive rods 211. A rotating shaft 212 is fixedly connected to one of the drive rods 211. The rotating shaft 212 connects between the two drive rods 211. By rotating the rotating shaft 212, one of the drive rods 211 is driven to make a circular motion, which can unfold the flexible fireproof cover 2. In the unused state, the flexible fireproof cover 2 is in a folded state. After unfolding, it forms a flexible cover. The rotating shaft 212 passes through the partition plate 122 and a drive motor 213 for driving the rotating shaft 212 is fixedly provided at the other end. The distribution box 1 A smoke sensor 13 is installed at the top. The smoke sensor 13 can be connected to the drive motor 213. When the smoke sensor 13 detects smoke, it will drive the drive motor 213 to start and unfold the flexible fireproof cover 2. The drive assembly 21 also includes a drive rack 214. The output end of the drive motor 213 is fixedly connected to a transmission block 215. The transmission block 215 meshes with one end of the drive rack 214, and the rotating shaft 212 meshes with the other end of the drive rack 214. Through rack and pinion transmission, one drive motor 213 can simultaneously unfold the fireproof cover of the upper and lower power distribution parts 12.

[0022] refer to Figures 1-4 An annular sealing strip 124 is fixedly installed on the top of the partition plate 122. The annular sealing strip 124 is made of fireproof material.
