[0020] like Figure 1-4As shown, the utility model has a new steel fire door structure, including a fireproof inner plate 1, a steel frame 2 and a fireproof panel 3. The front of the steel frame 2 is fixedly installed with the fireproof panel 3, the back of the steel frame 2 is fixedly provided with a fireproof inner plate 1, the top and bottom ends of the steel frame 2 are fixedly installed with control boxes 5, a reinforcing rib 7 is fixedly installed between the two control boxes 5, a high-pressure pump 11 and a dry powder tank body are fixedly installed inside the two control boxes 5, the feed end of the high-pressure pump 11 is connected to the dry powder tank body, a plurality of nozzles are fixedly provided on the outer wall of the control box 5 at equal intervals, the discharge end of the high-pressure pump 11 is connected to the plurality of nozzles, a temperature control switch 12 is fixedly installed on one side of the inner wall of the steel frame 2, and the high-pressure pump 11 is electrically connected to an external power supply through the temperature control switch 12.

[0021] Specifically, the fireproof board is assembled by a fireproof inner board 1, a fireproof panel 3 and a steel frame 2. A temperature control switch 12 is arranged inside the steel frame 2 and a dry powder tank is placed inside the control box 5. When the temperature reaches the set temperature of the temperature control switch 12, fire prevention is carried out by spraying dry powder, thereby improving the fireproof performance of the fire door.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the new steel fire door structure of the utility model, a plurality of connecting columns 9 are fixedly provided at equal intervals on the side of the back side of the fire panel 3, a plurality of assembly holes 6 compatible with the connecting columns 9 are opened at equal intervals on the side of the steel frame 2, a plurality of connecting holes 10 are opened at equal intervals on the front side of the fireproof inner panel 1, and a plurality of connecting columns 9 pass through the assembly holes 6 and are nested and connected with the corresponding connecting holes 10.

[0023] A rectangular groove 14 is provided at the end of the connecting column 9, and clamping columns 17 are inserted and connected on both sides of the rectangular groove 14. A reset spring 16 is fixedly installed between the two clamping columns 17. Clamping holes 15 are provided on both sides of the inner wall of the connecting hole 10, and the two clamping columns 17 are clamped and connected with the corresponding clamping holes 15.

[0024] Specifically, through the cooperation between the connecting column 9 and the connecting hole 10, the cooperation between the fireproof inner plate 1, the steel frame 2 and the fireproof panel 3 is facilitated, and the assembly of the fireproof door is facilitated. The connecting column 9 and the connecting hole 10 are fixed by the cooperation between the clamping column 17 and the clamping hole 15, which facilitates the fixation of the connecting column 9.

[0025] The inside of the fireproof inner plate 1 and the fireproof front plate 3 are fixedly bonded with rock plates 4, and the connection between the fireproof inner plate 1 and the fireproof front plate 3 and the steel frame 2 is filled with sound insulation cotton blocks 13.
