When the sensor 601 detects smoke or overheating inside the distribution box body 1 When a fire occurs, when the movable plate 311 is pushed to its original position, one end of the positioning link 3014 is stuck in one of the first positioning grooves 3012. At this time, one end of the positioning link 3014 will break at the groove 3015. During this process, the positioning rod 3017 is pushed by the second spring 3016. When the movable frame 3 moves to its original position, the positioning rod 3017 will be pushed by the second spring 3016 to the second positioning groove 3013 in another first positioning groove 3012, thereby fixing the position of the movable frame 3 and achieving a better isolation effect.

The baffle 5012 fits with the heat dissipation slot 5. The baffle 5012 can be controlled to rotate by the servo motor 5011. The size of the heat dissipation slot 5 can be adjusted by rotating the baffle 5012. When the sensor 601 detects smoke or overheating and fire inside the distribution box body 1, the baffle 5012 can be controlled to move to block the heat dissipation slot 5 to isolate the outside air.

A blocking hole 303 is opened on the top of the movable plate 311. One end of the fourth spring 3031 is fixedly installed on the inner wall of the blocking hole 303. The blocking piece 3032 is fixedly installed on the other end of the fourth spring 3031. The blocking piece 3032 fits with the heat dissipation hole 105. A matching hole 302 that penetrates the movable plate 311 is opened inside the movable plate 311. The matching hole 302 corresponds to the heat dissipation hole 105. By setting the heat dissipation hole 105, the hot air inside the distribution box body 1 can be dissipated through the heat dissipation hole 105. By setting the dust filter 1051, external dust can be prevented from entering the distribution box body 1 through the heat dissipation hole 105.

[0067] The fourth spring 3031 is provided to support the blocking member 3032.

[0069] Several mounting grooves 401 are matched with the mounting parts 403. By setting the through holes 4031, the mounting parts 403 can slide on the side walls of the guide rails 4032, so that the moving direction of the mounting parts 403 can be limited by the guide rails 4032, and the moving range and direction of the mounting parts 403 in the movable grooves 4011 can be limited. By setting the fifth spring 4033, the mounting parts 403 can be supported, so that the mounting parts 403 can be inserted into the mounting grooves 401, so that the partition 4 can be fixed inside the distribution box body 1. By adjusting the mounting parts 403 to insert them into different mounting grooves 401, the position of the partition 4 inside the distribution box body 1 can be adjusted, so that the internal space of the distribution box body 1 can be freely adjusted.

[0070] In some embodiments, see Figure 8 , Fig. 9 A toggle groove 402 is provided on one side of the movable groove 4011, and a toggle member 4021 is fixedly installed on one side of the mounting member 403. The toggle member 4021 is slidably connected inside the toggle groove 402. By setting the toggle groove 402, the toggle member 4021 can be protruded from one side of the partition 4, so that the toggle member 4021 can be easily moved. By installing the toggle member 4021 on one side of the mounting member 403, the movement of the mounting member 403 can be conveniently controlled.

[0071] The working process and principle of the present invention are as follows: when the distribution box body 1 is used alone, the movable frame 3 and the movable plate 311 can block the top and bottom of the distribution box body 1, so that the distribution box body 1 is a separate whole. When the distribution box body 1 is used in combination, the positioning link 3014 is retracted from one of the first positioning grooves 3012 to the slide groove 3011 by rotating the adjusting member 301, and then the movable frame 3 is pushed to make the movable plate 311 completely retracted into the movable cavity 106. Then, the adjusting member 301 is rotated to make the positioning link 3014 snap into the other first positioning groove 3012 for fixing. At this time, the movable member 201 on one side of the movable door 2 will be under the action of the torsion spring. Rotate to be parallel to the movable door 2, and then connect the two distribution box bodies 1 with the connecting slot 103 through the connecting bracket 101, and then fix them in the threaded hole 104 through the fixing bolt passing through the mounting hole 102 to complete the combination of the distribution box body 1. At this time, the movable part 201 is magnetically connected to the movable part 201 inside the other distribution box body 1 through the magnetic connector 2011, so that the distribution box bodies 1 are combined into a whole. When the distribution box body 1 is connected for use, the movable plate 311 will slide to make the matching hole 302 correspond to the heat dissipation hole 105, so that the heat dissipation holes 105 inside the connected distribution box bodies 1 can be connected to perform heat dissipation, thereby achieving better heat dissipation effect.

[0072] The handle 204 can be used to conveniently control the opening and closing of the movable door 2. When the sensor 601 detects that one of the distribution box bodies 1 is smoking or overheating and catching fire, the electric push rod 6021 is operated to push the support member 6023 to move, so that the support member 6023 pushes the movable plate 311 to move to its original position. During the movement, one end of the positioning link 3014 is stuck in one of the first positioning grooves 3012. At this time, one end of the positioning link 3014 will be broken at the groove 3015. In this process, the positioning rod 3017 is clamped by the second spring. The second spring 3016 pushes the positioning rod 3017, and when the movable frame 3 moves to the original position, the positioning rod 3017 will be pushed by the second spring 3016 to the second positioning groove 3013 in another first positioning groove 3012 to fix the position of the movable frame 3. During the movement, the movable frame 3 on the side of the movable plate 311 will push the movable part 201 on the side of the movable door 2 to rotate to one side. At the same time, the servo motor 5011 controls the baffle 5012 to move and block the heat dissipation groove 5, so as to isolate the external air and put the distribution box body 1 in an isolated state.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
