[0011] The utility model provides a metal armored central removable switch cabinet, which has the following beneficial effects:

[0012] 1. The metal armored central removable switch cabinet has the effect of improving the sealing performance through the arrangement of the first spring, the first top block, the first sealing block, the second spring, the second top block and the second sealing block. When in use, when closing the cabinet door, under the action of the pad and the pressure groove, the pad is pressed in the pressure groove, and then it needs to be closed from bottom to top in sequence. During the closing process of the third cabinet door, the second cabinet door and the first cabinet door, the second sealing block on the inner side of the cabinet door will come into contact with the first sealing block. As the cabinet door is closed, the second sealing block and the first sealing block squeeze each other, causing the second top block and the first top block to slide into the second groove and the first groove respectively. As the cabinet door is completely closed, the second sealing block and the first sealing block squeeze each other and deform under the action of the second spring and the first spring, thereby playing a sealing role. After the cabinet door is closed, the rotating block is rotated again so that the clamping column at the other end of the rotating block is inserted into the clamping groove to complete the closing. By arranging the first sealing block and the second sealing block around the cabinet door, a better sealing effect is achieved, preventing external substances from entering and causing damage to the equipment or malfunctioning, effectively preventing the spread of electric arcs, reducing the occurrence of electrical accidents, improving the safety of the equipment, and achieving the purpose of improving safety.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0021] See also Figures 1 to 6 The utility model provides a technical solution: a metal armored central removable switch cabinet, comprising a switch cabinet body 1, a first cabinet door 2 is hingedly connected to the upper part of the switch cabinet body 1, and a second cabinet door 3 is hingedly connected to the middle part of the switch cabinet body 1. The sides of the second cabinet door 3 and the third cabinet door 4 are both provided with fixed blocks 5, rotating blocks 6, clamping columns 7 and handles 8, and corresponding U-shaped blocks 9 are provided at the corresponding positions. The third cabinet door 4 is hingedly connected to the lower part of the switch cabinet body 1. The side of the first cabinet door 2 is fixedly connected with the fixed block 5, and the surface of the fixed block 5 is rotatably connected with the rotating block 6 through a rotating shaft. The surface of the other side of the rotating block 6 is fixedly connected with the clamping column 7, and the surface of the clamping column 7 is fixedly connected with the handle 8. The side of the switch cabinet body 1 is fixedly connected with the U-shaped block 9, and the surface of the U-shaped block 9 is provided with a clamping groove 10. The closed surface of the switch cabinet body 1 is provided with a first groove 11, and the inner surface of the first groove 11 is fixedly connected with a first spring 12, and the other end of the first spring 12 is fixedly connected with a first top block 13, and the surface of the first top block 13 is provided with a first sealing block 14. The second cabinet door 3 and the third cabinet door 4 are all provided with a second groove 15, a second spring 16, a second top block 17 and a second sealing block 18 around the inner side surfaces. The closing surface of the main body 1 is provided with a first groove 11, a first spring 12, a first top block 13 and a first sealing block 14 at positions corresponding to the second cabinet door 3 and the third cabinet door 4. A second groove 15 is provided around the inner side surface of the first cabinet door 2. The inner side surface of the second groove 15 is fixedly connected with a second spring 16. The other end of the second spring 16 is fixedly connected with a second top block 17. The surface of the second top block 17 is provided with a second sealing block 18. After the first cabinet door 2, the second cabinet door 3 and the third cabinet door 4 are closed, the positions of the first groove 11 and the second groove 15 are compared, and the first sealing block 14 and the second sealing block 18 abut against each other. A cushion block 19 is fixedly connected to the upper surface of the second cabinet door 3, and a pressing groove 20 is provided on the lower surface of the first cabinet door 2.
