[0002] Light core fire-resistant composite structure fire door is a door with special fire resistance. Its structure is mainly composed of door frame and door leaf. The door frame is generally made of metal to ensure the stability of the structure. The door leaf is the core part and adopts a composite structure, including light core material as the fire door core. This door core material has the characteristics of light weight and good fire resistance. The door core is wrapped or compounded with flame retardant panels to play a protective and decorative role.

[0003] The existing fire doors have good thermal insulation properties, which can better protect the wood core, avoid damage to the wood core and extend the service life. Some fire doors are used in warehouses to prevent the spread of fire. However, if a fire occurs, the fire source contacts the fire door and causes the door handle to be locked, which will prevent rescuers from opening the fire door to escape, thereby causing the fire door to be less safe.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention will be further described below in conjunction with the embodiments.

[0033] Example: Refer to Figure 1 and Figure 2 The present invention provides a technical solution: a light core fire-resistant composite structure fireproof door and a manufacturing method thereof, comprising: a door panel 1, a door lock 10, a door handle 11 and a fire sprinkler 14, characterized in that a triangular water tank 12 is fixedly installed on one side of the door panel 1, the inner wall of the triangular water tank 12 is provided with a hydraulic heat dissipation mechanism, and the outer wall of the triangular water tank 12 is provided with a telescopic antifreeze mechanism. When the door panel 1 is turned over, the telescopic antifreeze mechanism contacts the wall surface and causes the liquid in the triangular water tank 12 to flow;

[0034] The outer wall of the door lock 10 can be rotatably connected to one end of the door handle 11. When the door handle 11 needs to be turned over to turn over the door panel 1, the door handle 11 can be turned down through the hydraulic heat dissipation mechanism, and then the door panel 1 can be pushed open. After the temperature rises, the fire sprinkler 14 can spray water around the door panel 1 through the hydraulic heat dissipation mechanism.

[0035] like Figure 3 As shown, the top of the triangular water tank 12 is connected with an inflatable pipe 17, which is composed of a transverse pipe and a threaded pipe, and the transverse pipe and the threaded pipe are connected to each other, and the threaded pipe is threadedly connected with a threaded rod 18, and the inner wall of the threaded pipe is airtightly slidably connected with a piston 19, and the top of the piston 19 is fixedly installed on the bottom end of the threaded rod 18;

[0036] The inner wall of the triangular water tank 12 is airtightly slidably connected with a triangular piston 101 , the top of the triangular piston 101 and the inner top of the triangular water tank 12 have compressed gas, and the bottom of the triangular piston 101 and the inner bottom of the triangular water tank 12 have pure water.

[0037] When a fire occurs, the fire sprinkler 14 starts to spray water when it comes into contact with high temperature. Due to the imbalance of water pressure in the water outlet pipe 13, the compressed gas at the top of the triangular piston 101 and the inner top of the triangular water tank 12 will continue to push the triangular piston 101, allowing the pure water below the triangular piston 101 to enter the water outlet pipe 13, and finally the fire extinguishing work starts from the fire sprinkler 14 to the periphery of the door panel 1. When the staff needs to open the door panel 1, they only need to hold the handle rod 34 and flip it downward, and then flip the door handle 11, so that the door lock 10 can open the door panel 1. At the same time, through the hydraulic heat dissipation mechanism, the handle rod 34 can dissipate heat to the door handle 11 and the handle rod 34, so as to avoid scalding the hands of the rescue personnel;

[0038] During assembly, the staff ensures that there is pure water at the bottom of the triangular piston 101 and the inner bottom of the triangular water tank 12, and then manually rotates the threaded rod 18 to make the threaded rod 18 higher than the height of the horizontal tube and not separated from the inner wall of the threaded tube, and then injects compressed gas into the inflatable tube 17. Finally, the threaded rod 18 is manually rotated so that the inflatable tube 17 and the inner wall of the triangular water tank 12 are no longer in a connected state. At the same time, in order to ensure the stability of the pressure of the compressed gas, the staff can continue to manually rotate the threaded rod 18 to drive the piston 19 to move downward and then squeeze the compressed gas.

[0039] like Figures 3 to 5 As shown, the telescopic antifreeze mechanism includes a crescent-shaped telescopic rod 15 connected to the outer wall of the triangular water tank 12, the crescent-shaped telescopic rod 15 has a head end and a tail end, the outer wall of the head end is fixedly installed with a rubber head 16, the inner wall of the tail end is fixedly installed with a fixed rod 2 and a fixed rod 24, one side of the fixed rod 2 is rotatably connected with a gear 20, the gear 20 is meshed with a sawtooth rod 201, one side of the sawtooth rod 201 is fixedly installed on the inner wall of the head end, the end of the gear 20 away from the fixed rod 2 is fixedly installed with a bevel gear 21, the bevel gear 21 is meshed with a bevel gear 22, and the bevel gear 22 is meshed with a bevel gear 22. A rotating rod 23 is fixedly installed on one side of 22, and the rotating rod 23 is connected to the rotating rod 26 through a conveyor belt 25. One end of the rotating rod 23 passes through and is rotatably connected to one side of a fixed rod 24. The side of the fixed rod 24 near the bottom is rotatably connected to one end of the rotating rod 26. A crescent-shaped telescopic rod 27 is fixedly installed on one end of the rotating rod 26, and a conical liquid stirring head 29 is fixedly installed on the other end of the crescent-shaped telescopic rod 27. A fixed plate 28 is fixedly installed on one side of the serrated rod 201, and one end of the crescent-shaped telescopic rod 27 passes through and is rotatably connected to one side of the fixed plate 28.

[0040] In order to prevent the pure water in the triangular water tank 12 from freezing when the room temperature is low, if the pure water in the triangular water tank 12 is frozen, it will make it impossible to spray water to extinguish the fire. Therefore, whenever the staff pushes open the door panel 1, when the rubber head 16 at the head end of the crescent-shaped telescopic rod 15 contacts the wall, the rubber head 16 is made of a softer material, which can increase the contact area between the head end of the crescent-shaped telescopic rod 15 and the wall, thereby preventing the head end of the crescent-shaped telescopic rod 15 from scratching the wall. At the same time, when the crescent-shaped telescopic rod 15 is squeezed and shortened, it will drive the serrated rod 201 to move toward the triangular water tank 12, that is, the serrated rod 201 starts to move in a straight line, and drives the gear 20 to start rotating through meshing. The gear 20 meshes with each other through the bevel gear 1 21 and the bevel gear 2 22, thereby driving the rotating rod 1 23 to start rotating, and then the rotating rod 1 23 drives the rotating rod 2 26 and the crescent-shaped telescopic rod 2 27 to start rotating through the conveyor belt 1 25. Since the fixed rod 24 is fixed to the inner wall of the end of the crescent-shaped telescopic rod 15, the connection position of the rotating rod 26 and the crescent-shaped telescopic rod 27 does not move, and the serrated rod 201 drives the other end of the crescent-shaped telescopic rod 27 to move linearly, and the crescent-shaped telescopic rod 27 is in an extended length and rotating state. Finally, the conical liquid stirring head 29 is in a rotating and linear moving state in the water outlet pipe fitting 13, thereby increasing the flow rate of the pure water in the water outlet pipe fitting 13 and reducing the freezing rate of the pure water in the water outlet pipe fitting 13.

[0041] like Figure 1 and Figures 6 to 9As shown, the hydraulic heat dissipation mechanism includes a water outlet pipe 13 on the inner wall of the triangular water tank 12, and the water outlet pipe 13 has an upper water pipe and a lower water pipe. The outer wall of the upper water pipe passes through and is fixedly installed on the top of the triangular water tank 12, the outer wall of the lower water pipe passes through and is airtightly slidably connected to one side of the triangular piston 101, and a square groove 36 is opened at the bottom end of the lower water pipe. The outer wall of the lower water pipe is connected to a water filling pipe 44, and the inner wall of the water filling pipe 44 is airtightly rotatably connected to a hemisphere 45, and the flat surface of the hemisphere 45 is fixedly installed with an optical axis 46, and the top of the optical axis 46 is fixedly installed with a rectangular rod 47, the outer wall of the water filling pipe 44 can be clamped with an n-shaped rod 48, and the outer wall of the rectangular rod 47 can pass through and be slidably connected to one side of the n-shaped rod 48, the outer wall of the upper water pipe is connected to a water storage rod 30, and the inner wall of the water storage rod 30 is fixedly installed with a liquid separation plate. 31, a circular groove 32 is provided on one side of the water storage rod 30, and a circular tube 33 is rotatably connected to the inner wall of the circular groove 32, a handle rod 34 is fixedly installed on one side of the circular tube 33, and a liquid separation plate 35 is fixedly installed on the inner wall of the handle rod 34, and one-way valves 3 are provided on both sides of the liquid separation plate 31, and the water outlet ends of the two one-way valves 3 are opposite. The two one-way valves 3 are located between the outer wall of the liquid separation plate 31 and the inner wall of the water storage rod 30, and the water storage rod 30 and the inner wall of the handle rod 34 have pure water in two opposite flow directions, and a notch 4 is provided on the inner wall of the liquid separation plate 35, and the inner wall of the notch 4 is rotatably connected to a dorsal fin wheel 40, and the outer wall of the dorsal fin wheel 40 is connected to a heat dissipation wheel 42 through a conveyor belt 41, and one end of the heat dissipation wheel 42 is rotatably connected to a support plate 43, and the bottom of the support plate 43 is fixedly installed on the top of the handle rod 34.

[0042] When it is necessary to fill the inner wall of the triangular water tank 12 with water, the staff first removes the n-shaped rod 48, and then manually rotates the rectangular rod 47 to allow the hemispherical body 45 to open the inner wall of the water filling pipe 44, and then fills the inner wall of the water outlet pipe 13 with water through the water filling pipe 44. Finally, pure water enters the space formed by the bottom of the triangular piston 101 and the inner bottom of the triangular water tank 12 from the square groove 36 at the bottom of the lower water pipe. When a certain amount of pure water is filled, the staff can perform the reverse operation. At the same time, in order to avoid the water pressure pushing the hemispherical body 45 to open the inner wall of the water filling pipe 44 during the subsequent fire extinguishing work, it can be fixed by the n-shaped rod 48;

[0043] When the fire sprinkler 14 opens one side of the upper water pipe, the pressure imbalance compressed air in the triangular water tank 12 can squeeze the triangular piston 101 downward, and the pure water enters the inner wall of the water outlet pipe 13 from the square groove 36, and finally sprays out from the fire sprinkler 14 to extinguish the fire;

[0044] When it is necessary to fill the water outlet pipe 13 with water, the triangular piston 101 is attached to the inner top of the triangular water tank 12 by the buoyancy of the pure water, and then the excess pure water moves from the upper water pipe, and then the pure water passes through the cooperation between the water storage rod 30, the liquid separation plate 1 31, the handle rod 34, the liquid separation plate 2 35 and the two one-way valves 3. Because there is water flow on the left and right sides of the liquid separation plate 1 31 and the liquid separation plate 2 35, the pure water passes through the opposite water outlet ends of the two one-way valves 3 at the same time, as shown in the attached figure. Figure 6 As shown, pure water flows into the left side of the water storage rod 30, and at the same time, pure water flows out of the right side of the water storage rod 30 and enters the inner wall of the water outlet pipe 13, that is, the water flow in the water storage rod 30 and the handle rod 34 has fluidity, and can be transferred through the handle rod 34 to the top of the door handle 11, and finally the heat is driven by the flow of pure water, as shown in the attached figure. Fig. 9 As shown, the pure water between one side of the separator plate 35 and the inner wall of the handle rod 34 can drive the dorsal fin wheel 40 to rotate during the flow. When the dorsal fin wheel 40 is stationary, the dorsal fin sheet of its outer wall can completely block the airtight blockage between the handle rod 34 and one side of the separator plate 35. After the pure water drives the dorsal fin wheel 40 to rotate, the dorsal fin wheel 40 drives the heat dissipation wheel 42 to rotate through the conveyor belt 41 to dissipate heat, while also avoiding heat dissipation of the outer wall of the handle rod 34. When the rescuer needs to open the door panel 1, the rescuer only needs to manually bend the handle rod 34 downward, and finally the bottom of the handle rod 34 pushes the door handle 11 to allow the door lock 10 to open the door panel 1.

[0045] Furthermore, a method for manufacturing a light core fire-resistant composite structure fire door comprises the following steps:

[0046] S1. When the door panel 1, the hydraulic heat dissipation mechanism and the telescopic antifreeze mechanism need to be assembled, the staff first manually rotates the threaded rod 18 so that the bottom end of the threaded rod 18 is higher than the horizontal height of the transverse tube, and the transverse tube, the threaded tube, the triangular water tank 12 and the triangular piston 101 are in a connected state, and then the compressed gas is introduced into the transverse tube;

[0047] S2. When it is necessary to inject pure water into the inner wall of the triangular water tank 12, the staff first removes the n-shaped rod 48, then manually rotates the rectangular rod 47 clockwise 90 degrees to allow the hemispherical body 45 to open the inner wall of the water filling pipe 44, and finally injects pure water through the inner wall of the water filling pipe 44;

[0048] S3. When the staff opens the door panel 1, the door panel 1 starts to flip so that the head end of the crescent-shaped telescopic rod 15 contacts the wall, thereby driving the telescopic antifreeze mechanism to make the pure water in the triangular water tank 12 flow, thereby reducing the hardness of the pure water when it freezes. When a fire occurs, the staff drives the door handle 11 to open the door panel 1 by flipping the handle rod 34 downward.

[0049] Working principle: When a fire occurs, the fire sprinkler 14 starts to spray water when it comes into contact with high temperature. Due to the imbalance of water pressure in the water outlet pipe 13, the compressed gas at the top of the triangular piston 101 and the inner top of the triangular water tank 12 will continue to push the triangular piston 101, allowing the pure water below the triangular piston 101 to enter the water outlet pipe 13, and finally the fire is extinguished from the fire sprinkler 14 to the periphery of the door panel 1. When the staff needs to open the door panel 1, they only need to hold the handle rod 34 and flip it downward, and then flip the door handle 11, so that the door lock 10 can open the door panel 1. At the same time, through the hydraulic heat dissipation mechanism, the handle rod 34 can dissipate heat to the door handle 11 and the handle rod 34 to avoid scalding the hands of the rescue personnel;

[0050] During assembly, the staff first removes the n-shaped rod 48, and then manually rotates the rectangular rod 47 to allow the hemispherical body 45 to open the inner wall of the water filling pipe 44, and then fills the inner wall of the water outlet pipe 13 with water through the water filling pipe 44. Finally, the pure water enters the space formed by the bottom of the triangular piston 101 and the inner bottom of the triangular water tank 12 from the square groove 36 at the bottom of the lower water pipe. When a certain amount of pure water is filled, the staff can perform the reverse operation.

[0051] After ensuring that there is pure water at the bottom of the triangular piston 101 and the inner bottom of the triangular water tank 12, the staff manually rotates the threaded rod 18 to make the threaded rod 18 higher than the height of the horizontal tube and not separated from the inner wall of the threaded tube, and then injects compressed gas into the inflation tube 17. Finally, the threaded rod 18 is manually rotated so that the inflation tube 17 and the inner wall of the triangular water tank 12 are no longer in a connected state. At the same time, in order to ensure the stability of the pressure of the compressed gas, the staff can continue to manually rotate the threaded rod 18 to drive the piston 19 to move downward and then squeeze the compressed gas.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
