[0023] Referring to Figure 1 、 Figure 3 and Figure 4 An embodiment provided by the present utility model: A combined steel fire door includes a fireproof board 2. An I-shaped plate 25 is arranged at the front part of the fireproof board 2. A cover plate 9 is arranged at the rear part of the fireproof board 2. The fireproof board 2, the I-shaped plate 25 and the cover plate 9 are connected by fixed bolts 1. A door frame 4 is arranged outside the fireproof board 2. A sealing plate 6 is arranged at the lower side of the front part of the I-shaped plate 25. A rotating block 7 is arranged at the front part of the sealing plate 6. A sector plate 5 is fixedly connected to the lower part of the rotating block 7. The sector plate 5 is rotatably connected inside the sealing plate 6. A water storage bin 23 is arranged at the front part of the cover plate 9. A water outlet 24 is opened inside the I-shaped plate 25. A cavity 3 is opened inside the door frame 4. An installation component is arranged inside the cavity 3;

[0024] The I-shaped plate 25, the fireproof plate 2 and the cover plate 9 are assembled and connected by the fixing bolt 1. The multi-layer structure facilitates the transportation and installation of the steel fire door. It can still effectively prevent the spread of fire during a fire. By rotating the rotating block 7, the rotating block 7 drives the lower rotating plate to rotate, so that the clamping state between the sector plate 5 and the slot 12 can be released, so that the sealing plate 6 can be integrally withdrawn from the inside of the water outlet 24. At this time, the cooling water pre-injected through the inside of the water storage chamber 23 will quickly drain through the water outlet 24. The discharge of the cooling water can play a certain role in emergency fire extinguishing and ensure the safety of personnel's lives.

[0025] Refer to Figure 1 and Figure 3 , the installation component includes a movable plate 16. The movable plate 16 is arranged inside the cavity 3. A clamping rod 17 is fixedly connected to the lower part of the movable plate 16. A sliding block 14 is fixedly connected to the outside of the movable plate 16. A sliding groove 22 is opened inside the cavity 3. Springs 13 are fixedly connected to both sides of the upper part of the movable plate 16. The springs 13 are fixedly connected to the inner top of the cavity 3. A second limiting concave block 20 is arranged at the inner bottom of the cavity 3. An inserting plate 21 is arranged above the second limiting concave block 20. A first limiting concave block 18 is arranged on the right side inside the cavity 3. A pull rod 15 is fixedly connected to the middle side of the upper part of the movable plate 16;

[0026] By pulling the pull rod 15 inside the cavity 3, it slides in the sliding groove outside the cavity 3. The movement of the pull rod 15 pulls the movable plate 16 to move. The movement of the movable plate 16 drives the lower clamping rod 17 to slide. The inserting plate 21 is drawn in from the left and the inserting plate 21 is clamped into the first limiting concave block 18. At the same time, the pull rod 15 is loosened. The movable plate 16 is reset by the elastic force of the upper spring 13. The clamping rod 17 is aligned with the inside of the slot 19 of the inserting plate 21 and the second limiting concave block 20. By sliding the sliding block 14 inside the sliding groove 22, the movable plate 16 is fixed. After installation, by pulling the handle 8, the door panel can slide inside the door frame 4, and the steel fire door can be quickly disassembled and assembled, which is convenient for the staff to transport the steel fire door, improves the work efficiency of the staff, and at the same time improves the installation efficiency.

[0027] Refer to Figure 1 , Figure 3 and Figure 4, a handle 8 is provided at the front of the I-shaped plate 25. The slider 14 is slidably connected inside the chute 22. The clamping rod 17 is slidably connected inside the card slot 19 and the second limiting concave block 20. The insertion plate 21 is slidably connected inside the first limiting concave block 18. A connecting plate 10 is fixedly connected to the lower part of the fireproof plate 2. Steel balls 11 are provided at the lower part of the connecting plate 10. Grooves 12 are opened on both sides inside the water outlet 24. The sector plate 5 is slidably connected inside the grooves 12. By providing the handle 8, it is convenient to open and close the door panel. By sliding the slider 14 inside the chute 22, the movable plate 16 can slide smoothly. By sliding the clamping rod 17 inside the card slot 19 and the second limiting concave block 20, and the insertion plate 21 inside the first limiting concave block 18, the insertion plate 21 can be fixedly installed. By providing the steel balls 11 at the lower part of the connecting plate 10, the settlement of the door panel can be prevented. By providing the grooves 12, the sector plate 5 can be clamped inside the grooves 12 for fixed installation.

[0028] Working principle: When using this device, the I-shaped plate 25, the fireproof plate 2 and the cover plate 9 are fixedly connected through the fixing bolts 1. The multi-layer structure facilitates the transportation and installation of the steel fireproof door. In case of a fire, it can still effectively prevent the spread of fire. Pull the pull rod 15 inside the cavity 3 to slide in the external sliding groove. The movement of the pull rod 15 drives the movement of the movable plate 16. The movement of the movable plate 16 drives the lower clamping rod 17 to slide. Slide the insertion plate 21 in from the left and snap the insertion plate 21 into the first limiting concave block 18. At the same time, loosen the pull rod 15. The movable plate 16 is reset by the elastic force of the upper spring 13. Align the clamping rod 17 with the inside of the card slot 19 and the second limiting concave block 20 of the insertion plate 21. By sliding the slider 14 inside the chute 22, the movable plate 16 can be fixed. After installation, the door panel can slide inside the door frame 4, and the steel fireproof door can be quickly disassembled and assembled, which is convenient for the staff to transport the steel fireproof door. When a fire breaks out, rotate the rotating block 7 to drive the rotating plate to rotate, releasing the clamping state of the sector plate 5 and the groove 12, so as to draw out the sealing plate 6 from the inside of the water outlet 24. At this time, the cooling water injected in advance inside the water storage chamber 23 will quickly drain through the water outlet 24, which can play a certain role in emergency fire extinguishing and ensure the safety of personnel's lives. By providing the steel balls 11 at the lower part of the connecting plate 10 of the bottom plate, the settlement of the door panel can be prevented.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
