Description

Technical Field

[0001] The utility model relates to the technical field of fire doors, and more specifically, to a high-temperature resistant fire door. Background Art

[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. It is a fire partition with a certain fire resistance installed in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke, and can prevent the spread of fire for a certain period of time to ensure the evacuation of personnel.

[0003] The traditional high-temperature resistant fire door core board is usually integrally formed. After the outer surface of the door core board is burned by fire, the entire door core board has to be scrapped. However, due to its good fire resistance performance, its interior usually remains intact, and directly scrapping it is a great waste of materials. Summary of the Utility Model

An installation mechanism is provided inside the clamping grooves, and the installation mechanism includes insertion rods. A fixing plate is installed on one side of the top of the second door panel, and a cooling mechanism is provided inside the fixing plate. The cooling mechanism includes a number of atomizing nozzles.

[0007] Furthermore, the clamping block and the clamping groove are mutually clamped, and a slot is provided inside the clamping block. A through hole is provided on one side inside the clamping groove, and the through hole is communicated with the clamping groove.

[0009] Furthermore, two pairs of slide bars are installed on both outer sides of the reinforcement layer, and springs are sleeved on the outer sides of the slide bars. A slide plate is slidably installed on the outer sides of one pair of slide bars, and one ends of a pair of springs are connected to the slide plate respectively.

[0010] The beneficial effect of adopting the above further solution is that by installing the slide plate, the insertion rod can be driven to move up and down, so that the insertion rod is engaged with or separated from the clamping block, increasing the convenience of disassembly.

[0011] Furthermore, a pair of insertion rods are installed at the bottom of the slide plate, and the insertion rods penetrate through the through holes and are engaged with the slots. A handle is installed at the top of the slide plate.

[0016] Furthermore, the bottom ends of the plurality of second water pipes all penetrate through the fixed plate and are installed with atomizing nozzles. One side of the first door panel is hinged with a hinge, and one side of the hinge is hinged with the installation frame.

[0017] The beneficial effect of adopting the above further solution is that by installing the atomizing nozzles, water can be sprayed for cooling when the temperature is too high, ensuring safety, avoiding overheating, and improving heat resistance.

[0018] The beneficial effects of the present utility model are as follows: A high-temperature resistant fire door obtained by the above design in the present utility model installs the installation block in the installation groove, then inserts the clamping block into the clamping groove, pulls the sliding plate to move the insertion slot out of the through hole. After the clamping block is engaged with the clamping groove, release the sliding plate, and through the elasticity of the spring, the insertion rod is inserted into the insertion slot through the through hole to fix the clamping block, so that the first door panel, the second door panel and the reinforcement layer are connected together. Then, by installing the hinge, the protective door is installed and used. During the use process, by providing a high-temperature resistant layer, the high-temperature resistance of the door panel can be increased, and the probability of being damaged by high temperature can be reduced. In case of a fire or high temperature, water can be injected into the first water pipe and the second water pipe in advance through the liquid injection pipe. When the temperature sensor senses high temperature, several atomizing nozzles can be started to spray water into the air to cool down, ensuring safety and avoiding overheating, and improving heat resistance. Then, when the first door panel or the second door panel is damaged, the first door panel or the second door panel can be replaced in time without replacing the internal structure, saving resources and reducing economic losses.

[0029] Embodiment 2 of a high-temperature resistant and fireproof door of the present utility model

[0030] Refer to, specifically as Figures 1 - 4, a temperature sensor 3001 is installed on one side of the outer part of the installation frame 1001, a liquid injection pipe 3002 is installed on one side of the top of the installation frame 1001, and a liquid injection port 3003 is arranged inside the liquid injection pipe 3002.

By installing the atomizing nozzles 3007, water can be sprayed for temperature reduction when the temperature is too high, ensuring safety, avoiding overheating, and improving heat resistance.

[0031] Specifically, the working principle of this high-temperature resistant and fire-proof door: During use, install the installation block 1005 in the installation groove 1002, then insert the clamping block 2006 into the clamping groove 2008, pull the sliding plate 2010 to move the slot 2007 out of the through hole 2013. When the clamping block 2006 is engaged with the clamping groove 2008, release the sliding plate 2010. Through the elasticity of the spring 2011, the inserting rod 2012 is inserted into the slot 2007 through the through hole 2013 to fix the clamping block 2006, connecting the first door panel 1003 with the second door panel 1008 and the reinforcement layer 2002 together. Then, by installing the hinge 1007, the protective door is installed and used. During the use process, by providing the high-temperature resistant layer, the high-temperature resistance of the door panel can be increased, reducing the probability of being damaged by high temperature. When a fire occurs or the temperature is relatively high, water can be injected into the first water pipe 3005 and the second water pipes 3006 in advance through the liquid injection pipe 3002. When the temperature sensor 3001 senses a relatively high temperature, a number of atomizing nozzles 3007 can be started to spray water into the air for temperature reduction, ensuring safety, avoiding overheating, and improving heat resistance. Then, when the first door panel 1003 or the second door panel 1008 is damaged, the first door panel 1003 or the second door panel 1008 can be replaced in time without replacing the internal structure, saving resources and reducing economic losses.
