[0021] By Figures 1 to 7Given that, the utility model includes an insulating protective cover body 1. A connecting frame 2 is fixedly installed at the top of the insulating protective cover body 1. A rotating shaft 3 is rotatably installed inside the connecting frame 2. Two fixed sleeves 5 are fixedly installed on the surface of the rotating shaft 3. Support arms 6 are fixedly installed on the surfaces of the two fixed sleeves 5. An active protective cover 7 is fixedly installed between one ends of the two support arms 6. A frame-shaped groove 10 is formed on the front side of the insulating protective cover body 1. A hollow gasket 11 is fixedly installed inside the frame-shaped groove 10. A clamping frame 12 is fixedly installed at the front part of the active protective cover 7. A clamping and positioning component is provided between the bottom of the insulating protective cover body 1 and the top of the active protective cover 7.

[0022] During use, the operator installs the power distribution equipment inside the insulating protective cover body 1, and then rotates the active protective cover 7 to close it. When the active protective cover 7 rotates, it drives the rotating shaft 3 to rotate along the inside of the connecting frame 2 through the two support arms 6 and the two fixed sleeves 5. When the active protective cover 7 rotates and closes, it drives the clamping frame 12 to be inserted into the hollow gasket 11 inside the frame-shaped groove 10. At the same time when the active protective cover 7 rotates and closes, it also inflates the inside of the hollow gasket 11 through the clamping and positioning component, so that the hollow gasket 11 expands, and then tightly wraps the clamping frame 12, making it have a good sealing effect. At the same time, the clamping and positioning component also clamps and limits the active protective cover 7, so as to ensure the sealing effect.

[0023] The clamping and positioning component includes a mounting plate 8 and a mounting box 9. The mounting plate 8 is fixedly installed at the top of the active protective cover 7. The mounting box 9 is fixedly installed at the bottom of the insulating protective cover body 1. An extrusion block 13 is fixedly installed in the middle of one side of the mounting plate 8. Two insertion rods 14 are fixedly installed at the upper part of one side of the mounting plate 8. A limiting groove 15 is fixedly installed on the mutually remote side of the two insertion rods 14. An air storage bag 16 is fixedly installed inside the mounting box 9. An air inlet and outlet nozzle 17 is fixedly installed at the top of the air storage bag 16. The top of the air inlet and outlet nozzle 17 extends into the frame-shaped groove 10 and is fixedly connected to the hollow gasket 11. Slots 18 are formed on both sides of the lower part of the front of the mounting box 9; Limiting blocks 22 are provided inside the two slots 18. A rectangular rod 20 is fixedly installed on the mutually remote side of the two limiting blocks 22. Rectangular sleeves 19 are fixedly installed on both sides of the mounting box 9. The two rectangular rods 20 are inserted into the two rectangular sleeves 19. Springs 23 are provided on the surfaces of the two rectangular rods 20. Both ends of the two springs 23 are respectively fixedly connected to the limiting blocks 22 and the rectangular sleeves 19. Fixed pull rings 21 are fixedly installed at the mutually remote ends of the two rectangular rods 20; Positioning sliding sleeves 24 are fixedly installed at the bottoms of the limiting blocks 22. Positioning sliding rods 25 are inserted into the two positioning sliding sleeves 24. The mutually remote ends of the two positioning sliding rods 25 are respectively fixedly connected to the inner walls of the two slots 18.

[0024] While the movable protective cover 7 rotates and closes, it will also drive the extrusion block 13 into the interior of the mounting box 9 through the mounting plate 8 to extrude the air storage bag 16, and at the same time insert the two insertion rods 14 into the two slots 18. When the air storage bag 16 is extruded, the gas inside it will be input into the hollow gasket 11 through the air inlet and outlet nozzle 17, so that the hollow gasket 11 expands. While the two insertion rods 14 are inserted into the two slots 18, they will push the two limit blocks 22 to move away from each other. When the limit blocks 22 move, they both drive the positioning sliding sleeve 24 to slide along the surface of the positioning slide rod 25, increasing the stability of the limit blocks 22 when they move. When the two limit blocks 22 move away from each other, they both drive the rectangular rod 20 to move outward along the interior of the rectangular sleeve 19 and simultaneously squeeze the spring 23. When the two limit slots 15 on the two insertion rods 14 reach the positions of the two limit blocks 22, the two springs 23 both push the two limit blocks 22 into the two limit slots 15 through their own elastic forces for limiting, thus ensuring the extrusion effect of the extrusion block 13 on the air storage bag 16.
