There are two trigger components 83, which are respectively arranged at the lower ends of the front and rear sides of the placement groove 4 and are fixedly connected to the door panel 2.

[0024] The above scheme is adopted: by setting an auxiliary device 8, which is used to lift and lower the fireproof glass 5 of the fire door, so that it can be pulled down and opened in daily life to facilitate ventilation, and closed in case of fire to continue fire prevention.

[0025] refer to Figure 2 and Figure 3The placement component 81 includes a frame 811, a pull plate 812 and a slide bar 813. The frame 811 is arranged in the recovery groove 6 and is slidably connected to the recovery groove 6. The glass 5 is fixedly connected in the frame 811. The upper end of the frame 811 extends into the placement groove 4. The pull plate 812 is arranged in the placement groove 4 and is fixedly connected to the upper end of the frame 811. There are two slide bars 813, which are respectively fixedly connected to the left and right side surfaces of the frame 811, and one end of each extends into the two movable grooves 7.

[0026] The above solution is adopted: by setting a placement component 81, it is used to fix the glass 5 and enable the glass 5 to slide in the placement groove 4 and the recovery groove 6.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The lifting assembly 82 includes a moving rod 821, a moving block 822 and a tension spring 823. The moving rod 821 is arranged in the moving groove 7, and the upper and lower ends are respectively fixedly connected to the upper and lower side surfaces inside the moving groove 7. The moving block 822 is sleeved on the lower end surface of the moving rod 821 and is slidably connected to the moving rod 821. One end of the moving block 822 extends into the placement groove 4 and is fixedly connected to the pull plate 812. The tension spring 823 is sleeved on the surface of the moving rod 821, and the upper and lower ends are respectively fixedly connected to the upper surface of the moving groove 7 and the upper surface of the moving block 822.

[0028] The above solution is adopted: by setting a lifting component 82 to pull up the placement component 81 and give the placement component 81 an upward pulling force, the glass 5 can be lifted and closed in case of fire.

[0029] refer to Figure 1 and Figure 4 The trigger assembly 83 includes a fixed seat 831, a rotating ring 832 and a fuse rope 833. The fixed seat 831 is arranged at the lower end of the placement groove 4 and is fixedly connected to the surface of the door panel 2. The rotating ring 832 is arranged above the fixed seat 831, and the right end is rotatably connected to the fixed seat 831. The fuse rope 833 is arranged at the left end of the rotating ring 832, and the upper and lower ends are respectively fixedly connected to the left end of the upper surface of the fixed seat 831 and the left end of the lower surface of the rotating ring 832.

[0030] The above solution is adopted: by setting a trigger component 83, it is used to cooperate with the blocking rod 10 to resist the placement component 81 after being pulled down to position it. In the event of a fire, the placement component 81 will be released to rise and close.

[0031] refer to Figure 3 A sealing strip 9 is provided on the upper surface of the pull plate 812 , and the sealing strip 9 is fixedly connected to the pull plate 812 .

[0032] The above solution is adopted: by arranging a sealing strip 9 on the upper surface of the pull plate 812, it has the function of further sealing the upper end of the placement component 81 when it is raised and closed, and the sealing strip 9 is also made of fireproof material.

[0033] refer to Figure 1 and Figure 4 A blocking rod 10 is arranged inside the placement groove 4, and both ends of the blocking rod 10 extend between the rotating ring 832 and the fixed seat 831 respectively.

[0034] The above solution is adopted: by setting a blocking rod 10 to support the top of the placement component 81 after being pulled down, the placement component 81 is positioned. When a fire occurs, the trigger component 83 will be released to release the placement component 81.

[0035] The working principle of this utility model:

[0036] When a fire occurs, the fire and high temperature will melt the fuse rope 833. When the fuse rope 833 is melted, the tension spring 823 will pull back, pulling the moving block 822 upward on the surface of the moving rod 821. At the same time, the moving rod 821 drives the pull plate 812 to rise. When the pull plate 812 rises, it will push the blocking rod 10 upward. Since the fuse rope 833 has been melted at this time, when the blocking rod 10 is pushed up, the rotating ring 832 is pushed up and rotated open on the fixed seat 831, thereby releasing the blocking rod. 10 is connected, the blocking rod 10 will be pushed down, so that the frame 811 in the recovery groove 6 will continue to be pulled into the placement groove 4, and the slide bar 813 moves in the movable groove 7, and has a sealing effect at the same time. After being pulled until the sealing strip 9 contacts the upper surface of the placement groove 4, the closure is completed. In daily life, the placement component 81 is pulled down to the recovery groove 6, and the two ends of the blocking rod 10 are inserted between the rotating ring 832 and the fixed seat 831 to support the placement component 81 for ventilation.

[0037] To sum up: the steel fire door structure, through the arrangement of door frame 1, door panel 2, closer 3, placement slot 4, glass 5, recovery slot 6, moving slot 7, auxiliary device 8, placement component 81, frame 811, pull plate 812, slide bar 813, lifting component 82, moving rod 821, moving block 822, tension spring 823, trigger component 83, fixed seat 831, rotating ring 832, fuse rope 833, sealing strip 9 and blocking rod 10, solves the problem that the existing fire door is usually closed and has good sealing performance in order to isolate the fire scene and prevent smoke diffusion from causing coma. In daily life, closing the fire door will affect the indoor air circulation and affect the indoor air quality.
