[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] like Figures 1-5 As shown, a fireproof metal door comprises a metal door frame 1, a hinge 11 is hinged on the side of the metal door frame 1, a fireproof door 12 is fixedly connected to the side of the hinge 11, and a precipitation device 2 is arranged on the side of the metal door frame 1;

[0026] The precipitation device 2 includes an intelligent water tank 21. The side of the intelligent water tank 21 is fixedly connected to the side of the metal door frame 1. A smoke detector 22 is fixedly connected to the side of the intelligent water tank 21. The smoke detector 22 is used to detect the smoke during a fire. A delivery tank 23 is fixedly connected to the side of the intelligent water tank 21. A delivery pipe 24 penetrates through the side of the delivery tank 23. One end of the delivery pipe 24 away from the delivery tank 23 is fixedly connected to a connection box 25. A first spring 26 is fixedly connected to the inner wall of the connection box 25. One end of the first spring 26 away from the inner wall of the connection box 25 is fixedly connected to a connection plug 27. A spray pipe 28 penetrates through the top of the connection box 25. The spray pipe 28 is used to spray water flow.

[0027] According to the above structure, when a fire occurs, the fire generates smoke. Then, after the smoke detector 22 senses the smoke, it drives the intelligent water tank 21. After the intelligent water tank 21 is driven, the water inside enters the inside of the delivery tank 23. Then, the water flow is transmitted to the inside of the delivery pipe 24 through the delivery tank 23, and then enters the inside of the connection box 25 through the delivery pipe 24. When the water flow enters the inside of the connection box 25, the water flow presses against the side of the connection plug 27. After the connection plug 27 receives the extrusion force from the water flow, it starts to move towards the inner wall of the connection box 25. When the connection plug 27 moves, the connection plug 27 presses against the first spring 26 on the side. After the first spring 26 receives the extrusion force from the connection plug 27, it starts to contract. Then, the water flow starts to flow upward. When the water flow flows upward, the water flow enters the inside of the spray pipe 28. Then, the water flow is sprayed out through the spray pipe 28.

[0028] As Figure 2 shown, the smoke detector 22 is electrically connected to the intelligent water tank 21. The delivery pipe 24 is made of rubber material. The spray pipe 28 is set in an L shape. The spray holes of the spray pipe 28 are located directly above the fire door 12, which can ensure that the spray pipe 28 can effectively cover the entire upper area of the door during a fire. The bottom of the connection plug 27 is provided with an inclined surface. The setting of the inclined surface enables the connection plug 27 to move inward after being impacted by the water flow. The side of the connection plug 27 is located directly below the spray pipe 28. The bottom of the connection plug 27 with the inclined surface is located directly above the delivery pipe 24. The side of the connection plug 27 is slidably connected to the inner wall of the connection box 25. The connection plug 27 is in contact with the inner wall of the connection box 25.

[0029] According to the above structure, when the fire disappears, the smoke also disappears. When the smoke identifier 22 cannot identify the smoke, the smart water tank 21 stops running. The smart water tank 21 stops transmitting water to the delivery box 23, and the delivery box 23 also stops delivering water to the delivery pipe 24. When the delivery pipe 24 does not continue to deliver water, the extrusion force on the connecting plug 27 disappears. Then, the connecting plug 27 begins to move outward through the elastic force of the side spring 26. When the connecting plug 27 moves outward, the side of the connecting plug 27 contacts one end of the sprinkler pipe 28, and the sprinkler pipe 28 no longer sprays water outward. The spraying can quickly cool the surface temperature of the metal fire door 12, reduce the possibility of combustion, and can effectively reduce the damage to the door caused by the fire, thereby increasing the fire prevention time and barrier effect of the door.

[0030] like Figure 4 As shown, a ventilation device 3 is provided at the bottom of the connection box 25, and the ventilation device 3 includes a push rod 31, one end of the push rod 31 passes through and is slidably connected to the bottom of the connection box 25, one end of the push rod 31 is fixedly connected to a push block 32, the inner wall of the metal door frame 1 is fixedly connected to a fixing plate 33, the side of the fixing plate 33 is fixedly connected to a spring 2 34, the end of the spring 2 34 away from the fixing plate 33 is fixedly connected to a sealing plate 35, the sealing plate 35 can effectively seal the metal door frame 1 when not in use, the side of the sealing plate 35 is fixedly connected to a toggle block 36, the circumferential surface of the push rod 31 is fixedly sleeved with a spring 37, and the end of the spring 37 away from the push rod 31 is fixedly connected to the bottom of the connection box 25.

[0031] According to the above structure, when the connecting plug 27 moves toward the inner wall of the connecting box 25, the side of the connecting plug 27 is squeezed to one end of the push rod 31, and the push rod 31 begins to move downward after receiving the squeezing force from the connecting plug 27. When the push rod 31 moves downward, the push rod 31 squeezes the spring three 37. At the same time, the push rod 31 drives the bottom push block 32 to move downward. When the push block 32 moves downward, the side of the push block 32 is squeezed to the side of the toggle block 36. The toggle block 36 begins to move outward after receiving the squeezing force from the push block 32. When the toggle block 36 moves outward, the toggle block 36 drives the sealing plate 35 to start moving outward. When the sealing plate 35 moves outward, the sealing plate 35 is stretched to the spring two 34 on the side. At the same time, when the sealing plate 35 moves outward, a gap is generated between the contact surface of the sealing plate 35 and the fire door 12.

[0032] like Figure 5As shown, the side of the toggle block 36 is on the displacement track of the push block 32, the bottom of the sealing plate 35 is slidably connected to the inner wall of the metal door frame 1, and the top of the sealing plate 35 is slidably connected to the bottom of the fire door 12, thereby ensuring the sealing of the sealing plate 35 when not in use. A bevel is provided at one end of the push rod 31, and the end of the push rod 31 with the bevel is on the displacement track of the connecting plug 27, which is used to control the movement of the push rod 31.

[0033] According to the above structure, when the connecting plug 27 moves outward with the elastic force of the spring 1 26, the squeezing force of the connecting plug 27 on the push rod 31 disappears, and the push rod 31 starts to move upward through the elastic force of the spring 3 37. When the push rod 31 moves upward, the push rod 31 drives the push block 32 to start moving upward. When the push block 32 moves upward, the squeezing force of the push block 32 on the toggle block 36 disappears, and the toggle block 36 starts to move inward through the elastic force of the spring 2 34 on the side of the sealing plate 35, so that the sealing plate 35 returns to its original position after the fire disappears. When a gap is generated between the contact surface of the sealing plate 35 and the fire door 12, air permeability will help control the spread of the fire and maintain the isolation effect of the fire area and other areas. This can reduce the possibility of the fire spreading to other parts and reduce the overall disaster range.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
