AI Technical Summary
Existing fire doors cannot be closed automatically when a fire occurs, causing the fire to spread and cause losses to people and property in other areas.
A reinforced fire door is designed, using a support frame and a flammable adhesive product combustion plate to install the outside of the wall. When a fire occurs, the combustion of the combustion plate pushes the spring between the baffle and the support plate to rebound, pushing the fire door to automatically close. The rollers are used to operate in the long groove to drive the fire door to close, and the fire is controlled by cooling through the water tank and the spray head.
The fire door is automatically closed during a fire, preventing the fire from spreading, and protecting personnel and items through the spray head, enhancing the fire resistance performance of the fire door.

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the reinforced fireproof door provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 The left side schematic diagram shown; Figure 4 for Figure 1 The schematic cross-sectional view shown; Figure 5 for Figure 1 Schematic diagram of the internal architecture shown. The reinforced fire door comprises: a wall 1, a long block 2 is fixedly connected to the outside of the wall 1, a long groove 3 is provided on the top of the long block 2, a roller 4 is slidably connected inside the long groove 3, a short column 5 is movably connected inside the roller 4, one end of the short column 5 is fixedly connected to a limiting block 6, a straight slot 7 is provided on the outside of the long block 2, the short column 5 passes through the straight slot 7 and extends to the outside of the straight slot 7, the other end of the short column 5 is fixedly connected to a fixed block 8, a fire door 9 is fixedly connected to the bottom of the fixed block 8, a baffle 10 is fixedly connected to the outside of the fixed block 8 on the other side, a telescopic rod 11 is fixedly connected to one side of the baffle 10, a support plate 12 is fixedly connected to the other end of the telescopic rod 11, one end of the support plate 12 is fixedly connected to the outside of the long block 2, a spring 13 is arranged on the outside of the telescopic rod 11, a support frame 14 is fixedly connected to the outside of the wall 1, a support column 15 is movably connected inside the support frame 14, and combustion-supporting plates 16 are fixedly connected to both ends of the support column 15.
[0022] By opening a straight slot 7 on the outside of the long block 2, it is convenient for the short column 5 to slide inside the long slot 3. When no fire occurs, the baffle 10 is supported by the combustion-supporting plate 16, so that the spring 13 is always kept under pressure and stores power. When a fire occurs, the combustion-supporting plate 16 is exposed to high temperature and melts and burns. When the baffle 10 is not blocked by the combustion-supporting plate 16, the spring 13 releases force and pushes the baffle 10 to move forward. There is a certain distance between the support column 15 and the baffle 10 above the wall 1 to prevent the baffle 10 from being stuck by the support column 15 during operation.
[0023] An L-shaped rod 17 is fixedly connected to the top of the fire door 9, and a push rod 18 is fixedly connected to one side of the L-shaped rod 17. A water tank 19 is fixedly connected to the outside of the wall 1, and a rubber sheet 20 is fixedly connected to the outside of the push rod 18. The push rod 18 penetrates the water tank 19 and extends to the inside of the water tank 19. A push plate 21 is fixedly connected to the other end of the push rod 18. A square tube 22 is fixedly connected to the top of the water tank 19, and a hollow tube 23 is fixedly connected to the top of the square tube 22. A water outlet pipe 24 is fixedly connected to the outside of the hollow tube 23, and a sprinkler head 25 is fixedly connected to the other end of the water outlet pipe 24.
[0024] When the fire door 9 is pushed by the elasticity of the spring 13, the L-shaped rod 17 installed on the top of the fire door 9 is pushed to one side at the same time so that the pushing rod 18 on one side of the L-shaped rod 17 pushes the pushing plate 21 to squeeze the water in the water tank 19 to the middle, and the water reaches the inside of the hollow tube 23 through the square tube 22. The water pressure in the water tank 19 continues to increase, and the water in the hollow tube 23 is sprayed out through the sprinkler head 25, which effectively controls the fire outside the fire door 9 and cools down the temperature of the fire door 9, so that the people inside the fire door 9 are not burned by the high temperature.
[0025] A protrusion 26 is fixedly connected to the outside of the wall 1, a U-groove 27 is provided on one side of the fire door 9, the U-groove 27 is slidably connected to the protrusion 26, perlite 28 is fixedly connected to the inside of the fire door 9, and insulation cotton 29 is fixedly connected to the inside of the fire door 9.
[0026] Perlite 28 is fixedly connected inside the fire door 9. The perlite 28 has good heat insulation and flame retardant properties, can absorb heat and reduce the flame temperature. The insulation cotton 29 makes the temperature on one side of the fire door 9 low, so that people or objects on one side of the fire door 9 can be protected.
[0027] A storage box 30 is fixedly connected to the back of the wall 1 , a guide rail 31 is fixedly connected to the other side of the storage box 30 , a cover plate 32 is slidably connected to the outside of the guide rail 31 , and a handle 33 is fixedly connected to the other side of the cover plate 32 .
[0028] By placing escape supplies such as gas masks inside the storage box 30, the external guide rail 31 facilitates the cover plate 32 to slide open and close.
[0029] A routing plate 34 is fixedly connected to the back side of the wall 1 .
[0030] By drawing the escape route on the route board 34, as well as the method of using the gas mask.
[0031] An entrance 35 is formed outside the wall 1 , and an expansion rubber strip 36 is fixedly connected to the outside of the entrance 35 .
[0032] By installing an expansion strip 36 outside the entrance and exit 35, the expansion strip 36 expands at high temperature to fill the gap between the fire door 9 and the entrance and exit 35, thereby preventing toxic gases from entering.
[0033] The working principle of the reinforced fire door provided by the utility model is as follows: when a fire occurs, the combustion-supporting plates 16 at both ends of the support columns 15 inside the external support frame 14 of the wall body 1 are burned. After the combustion, the baffle 10 is not blocked by the combustion-supporting plates 16. A telescopic rod 11 is installed between the baffle 10 and the support plate 12, so that the distance between the baffle 10 and the support plate 12 can be shortened and extended. A spring 13 is arranged on the outside of the telescopic rod 11. When the baffle 10 is blocked, the spring 13 is in a force storage state. When there is no obstruction, it can rebound, providing power for the baffle 10, pushing the fire door 9 connected to the fixed block 8 to close, and a long groove 3 is arranged inside the long block 2, so that the roller 4 can roll inside, and at the same time, the roller 4 can lift the fire door 9 to avoid contact with the ground to increase resistance. When the fire door 9 is closed, the fire can be blocked outside the fire door 9 to avoid causing a larger fire.
[0034] Compared with the related art, the reinforced fireproof door provided by the utility model has the following beneficial effects:
[0035] The utility model provides a reinforced fire door, a support frame 14 is installed on the outside of the wall 1, and a support column 15 is arranged inside the support frame 14, which is convenient for extending a combustion-supporting plate 16. The combustion-supporting plate 16 is made of a flammable rubber product and can burn quickly when a fire occurs. The spring 13 between the support plate 12 and the baffle 10 is always kept in a compressed state. When the combustion-supporting plate 16 burns, the baffle 10 is not restricted. The elasticity of the spring 13 will push the baffle 10 to slide forward, and the roller 4 rotates inside the long groove 3 to drive the fire door 9 to close. When a fire occurs, the fire door 9 can be automatically closed.
