The triangular support seat 1, the support frame 2, the door body 3 and the balance frame 501 of the balance assembly 5 of the utility model are all pre-treated by sandblasting, rust removal, coating with anti-rust paint and spraying with heat insulation paint.

[0023] When the flap-type closed door of the utility model is in use, the moving block 8 is driven to move by utilizing the mobile driving mechanism 4, and the moving block 8 will drive the driving connecting rod 11 to move and rotate the angle, so that the driving connecting rod 11 drives the supporting frame 2 to rotate around the central axis 6, thereby driving the door body installed on the supporting frame 2 to rotate, and realize opening or closing. During the opening process of the door body 3, the balancing component 5 descends to a position to maintain the open state of the door body 3, and the anti-fall protection mechanism 12 is opened after the balancing component 5 reaches the specified position to realize anti-fall protection.

[0024] The balancing assembly 5 includes a balancing frame 501 and a balancing weight 502. The balancing frame 501 is installed at the tail end of the supporting frame 2. The balancing weight 502 is provided at one end of the balancing frame 501 away from the tail end of the supporting frame 2. A connecting seat 503 is provided at one end of the balancing frame 501.
