The inner top of the fixed plate 6 is rotatably connected with a second rotating shaft 11, and the second rotating shaft 11 is located on the inner side of the fixed groove 10. The outer end of the second rotating shaft 11 is fixedly connected with a movable plate 12, and a limiting groove 13 is cut at the middle end of the movable plate 12. The fixed groove 10 and the limiting groove 13 are matched with the upper end of the telescopic rod 9, and the internal temperature of the control cabinet can be effectively reduced by heat dissipation at multiple locations, thereby enhancing the service life of the internal electrical equipment. The inner end of the fixed plate 7 is fixedly connected with a second magnet 15, and the outer end of the movable plate 12 is fixedly connected with a first magnet 14, and the first magnet 14 is located in the limiting groove 13. The first magnet 14 and the second magnet 15 are fixedly connected to the surface of the first magnet 14 and the second magnet 15. When the movable plate 12 is closed, the first magnet 14 and the second magnet 15 attract each other to fix the movable plate 12, so that it is not easy to rotate. The rubber pad can protect the first magnet 14 and the second magnet 15 to reduce the damage caused by the collision between them. The inner top of the control cabinet housing 1 is fixedly connected with a heat conducting plate 4, and the upper end of the control cabinet housing 1 is provided with a breathable plate 5. A pair of card slots 17 are cut at the upper end of the control cabinet housing 1, and the left and right ends of the breathable plate 5 are fixedly connected with card blocks 16, the block 16 is engaged with the slot 17, and the hot air can be guided and concentrated through the heat conducting plate 4, and then discharged from the air permeable plate 5.
