Fixing bolts 15 are threadedly connected to the sides of the limiting heads 14 to limit the limiting plates 3. One end of the fixing bolts 15 is threadedly connected to the side of the fire door assembly 11.
[0029] A handle 4 is provided on the side of the fire door assembly 11. Rotating the handle 4 opens the fire door. The side of the fire door assembly 11 is fixedly connected to the mounting box 7. A connecting rod 6 is fixedly connected to the side of the handle 4. The end of the connecting rod 6 away from the handle 4 extends into the interior of the mounting box 7. The end of the connecting rod 6 extending into the interior of the mounting box 7 is rotatably connected to a pull rod 8. The pull rod 8 is used to pull the connecting rod 6, thereby rotating the handle 4. The lower end of the pull rod 8 is rotatably connected to a rotating frame 10 to facilitate the rotation of the pull rod 8. A foot pedal 9 is rotatably connected to the inner wall of the mounting box 7. The lower surface of the rotating frame 10 is fixedly connected to the upper surface of the foot pedal 9.
[0030] The mounting frame is coated with anti-corrosion paint on two sides, and the limiting plate is coated with anti-corrosion paint on three sides to improve its anti-corrosion performance.
[0031] The fire door assembly 11 includes an aluminum alloy panel 1101, a fireproof board 1102, and a base plate 1103. The two sides of the base plate 1103 are respectively bonded to the sides of the fireproof board 1102, and the sides of the fireproof board 1102 are bonded to the sides of the aluminum alloy panel 1101. The aluminum alloy panel 1101 improves the corrosion resistance, the fireproof board 1102 is used for fire protection, and the base plate 1103 is used to support the door structure and provide fire protection.
