Description

Technical Field

[0001] This utility model relates to the field of fire door structure technology, and more specifically, it relates to a fire door structure for fire safety. Background Technology

[0002] In existing technologies, when a fire occurs outside a fire door, a large amount of high-temperature, toxic smoke will be rapidly generated at the scene. This smoke has strong diffusion and penetrability, and will quickly seep into the inside of the fire door along the gaps left at the bottom of the fire door. Especially when the gap between the door and the ground is not equipped with a special smoke-blocking device, the smoke will enter the originally safe fire-resistant area uncontrollably, thus posing a serious threat to the life safety of people trapped inside.

[0003] Currently, some common fire door structures do not fill the inside of their door panels with dedicated fire-resistant and heat-insulating materials. This means that although the door body is not easily combustible in a short period of time during a fire, it is difficult to effectively block the conduction of heat energy. High temperatures may still be quickly transferred to the inside of the door through the metal door panel, causing the temperature of the inner surface of the door to rise rapidly, endangering the safety of people and items near the door.

[0004] In addition, existing fire door structures generally lack the design of sprinkler or water cooling components. Under the continuous action of high-temperature flames, even metal doors may be severely deformed, lose their airtightness or structural stability. If a water sprinkler system or cooling circuit can be added to the fire door structure, the door surface can be sprayed and cooled in the early stage of a fire, which can not only delay the temperature rise of the door, but also maintain the integrity and heat insulation performance of the door.

[0030] Please see Figures 1-5 A fireproof door structure for fire safety includes a door frame 1. A sealing assembly is provided on the door frame 1. The sealing assembly includes a hinge 2, a door body 3, an aluminum silicate plate 4, a rack 5, and a sealing plate 6. The hinge 2 is rotatably installed on the door frame 1. The door body 3 is installed at one end of the hinge 2. The aluminum silicate plate 4 is located at one end of the door body 3. The rack 5 is slidably connected to the aluminum silicate plate 4. The sealing plate 6 is connected to one end of the rack 5 and is inserted into the door frame 1. A fireproof assembly is provided inside the door body 3. The fireproof assembly includes a perlite plate 7, a fire extinguishing plate 8, and through holes 9. The perlite plate 7 is installed at one end of the door body 3. The fire extinguishing plate 8 is located between the perlite plate 7 and the aluminum silicate plate 4. The through holes 9 are evenly distributed on the fire extinguishing plate 8.

[0031] A gear 10 is rotatably connected to the aluminum silicate plate 4. The gear 10 meshes with the rack 5. A stabilizing block 11 is installed at one end of the gear 10. Stabilizing holes 12 are evenly opened on the stabilizing block 11. A rotating block 13 is installed at one end of the stabilizing block 11.

[0032] An mounting block 14 is installed on the aluminum silicate plate 4. A pull rod 15 is slidably connected to the mounting block 14. A pull plate 16 is connected to one end of the pull rod 15. A spring 17 is sleeved on the pull rod 15. Both ends of the spring 17 are connected to the mounting block 14 and the pull plate 16. One end of the pull rod 15 is inserted into the stabilizing hole 12.

[0033] A fire extinguishing bead 18 is installed on the through hole 9, and a second plate 19 is rotatably connected to the door frame 1.

[0034] One end of the second plate 19 is rotatably connected to the first rotating plate 20, and a placement block 21 is installed on the aluminum silicate plate 4. The placement block 21 is rotatably connected to the first rotating plate 20.

[0035] In this embodiment, during use, the door 3 is rotated and closed along the door frame 1 using its hinges 2, thus sealing it tightly. Then, the rotating block 13 drives the stabilizing block 11 to rotate, and during this rotation, it drives the gear 10 to rotate, causing the gear 5 to slide and move, thus inserting the sealing plate 6 at the top into the door frame 1, thereby blocking any possible gas leakage. Furthermore, during use, it is pulled using the pulling plate 16. The pulling rod 15 is moved, which stretches the spring 17. After the stabilizing block 11 is rotated to the appropriate position, the pulling rod 15 is released, and under the action of the elastic potential energy of the spring 17, it is driven to insert into the stabilizing hole 12 of the stabilizing block 11, thus stabilizing it. In use, by installing aluminum silicate board 4, perlite board 7 and fire extinguishing board 8 inside the door body 3, it serves to extinguish the fire. After the fire burns to a certain extent, it burns to the fire extinguishing beads 18 in the through hole 9 on the fire extinguishing board 8, thus using it to prevent fire.

[0036] Please see Figure 1-2 As a fire door structure implementation method for a sprinkler assembly: a sprinkler assembly is provided on the door frame 1. The sprinkler assembly includes a water tank 22, an inlet pipe 23 and a circulation pipe 24. The water tank 22 is located at one end of the door frame 1, the inlet pipe 23 is installed on the water tank 22, and the circulation pipe 24 is installed on the water tank 22.

[0037] Cooling pipes 25 are evenly installed on the circulation pipe 24, and a handle 26 is installed on one end of the aluminum silicate plate 4.

[0038] A pump body 27 is installed on the circulation pipe 24.

[0039] More specifically, during use, water is injected into the water tank 22 along the inlet pipe 23, and the water is drawn out along the circulation pipe 24 by the pump body 27, so that it is introduced into the cooling pipe 25 and flows out onto the door body 3, thereby protecting the door body 3 from the wetness, thus providing protection in a fire environment. When the handle 26 drives the door body 3 to rotate, the first rotating plate 20 at one end is driven to rotate by the placement block 21 on it, and the second plate 19, which is rotatably connected to the door frame 1, rotates in cooperation to complete the opening process of the door body 3.

[0040] In summary, during use or operation of the entire device: During use, the door 3 is rotated and closed along the door frame 1 using its hinges 2, thus sealing it tightly. Then, the rotating block 13 drives the stabilizing block 11 to rotate, which in turn drives the gear 10 to rotate. During this rotation, the gear 5, which meshes with the stabilizing block 11, slides, causing the sealing plate 6 at the top to insert into the door frame 1, thus blocking any potential gas leakage. Furthermore, during use, the device is pulled using the pulling plate 16. During the process, the pull rod 15 on it is moved, which stretches the spring 17. After the stabilizing block 11 is rotated to the appropriate position, the pull rod 15 is released, and under the action of the elastic potential energy of the spring 17, it is driven to insert into the stabilizing hole 12 of the stabilizing block 11, thus stabilizing it. In use, by installing aluminum silicate board 4, perlite board 7 and fire extinguishing board 8 inside the door body 3, it serves the purpose of extinguishing fire. After the fire burns to a certain extent, it burns to the fire extinguishing beads 18 in the through hole 9 on the fire extinguishing board 8, thus using it to prevent fire.

[0041] During use, water is injected into the water tank 22 through the inlet pipe 23, and the water is drawn out through the circulation pipe 24 by the pump body 27, so that it is introduced into the cooling pipe 25 and flows out onto the door body 3, thereby protecting the door body 3 from the wetness, thus providing protection in a fire environment. When the handle 26 drives the door body 3 to rotate, the first rotating plate 20 at one end is driven to rotate by the placement block 21 on it, and the second rotating plate 20, which is rotatably connected to the door frame 1, rotates to complete the opening process of the door body 3.
