Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a high-strength heat-insulating fire door. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and thermal insulation within a certain period of time. They are fire-resistant partitions installed in fire compartments, evacuation stairwells, vertical shafts, and other similar locations. In some refuges, they are specifically used to isolate fire sources and play a significant role in firefighting operations.

[0003] However, even after existing fire doors are closed, gaps remain between the two doors, allowing smoke to quickly spread and fill the entire area, increasing the risk of suffocation. Without effective barriers, visibility and air quality decrease significantly during a fire, making escape more difficult, severely impacting rescue efforts, and potentially leading to greater casualties and property damage. To address these issues, the inventors have proposed a high-strength, heat-insulating fire door. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-6 As shown, this utility model provides a high-strength heat-insulating fireproof door, including a first door 1 and a second door 11. The second door 11 is located to the side of the first door 1. The first door 1 and the second door 11 are installed inside the door frame, so that one side of the baffle 22 is located to the side of the escape passage. The outer side of the second door 11 is fixedly provided with symmetrically distributed external sliding tracks 2. The external sliding tracks 2 can limit the sliding strips 21. The sliding strips 21 are slidably provided on the outer side of the external sliding tracks 2. The two sliding strips 21 are fixedly connected to the baffle 22 at the end near the first door 1. The baffle 22 is located to the side of the first door 1 and the second door 11. An operating plate 23 is fixedly installed at the end away from the baffle 22. A pull rod 24 is slidably inserted into the outside of the operating plate 23. A circular groove 25 is symmetrically distributed inside the operating plate 23. A fixing plate 26 is fixedly installed on the outside of the pull rod 24. The fixing plate 26 is movably inserted into the circular groove 25. Two compression springs 27 are movably sleeved on the outside of the pull rod 24. The two compression springs 27 are respectively located in the two circular grooves 25. A slot 28 distributed in a rectangular array is opened on the outside of the second door 11. The pull rod 24 is movably inserted into the slot 28. The positioning of the baffle 22 is completed by inserting the pull rod 24 into the slot 28.

[0022] Both door 1 and door 2 are equipped with reinforcement components 3. The reinforcement components 3 include a first reinforcement plate 31, a second reinforcement plate 32, and thermal insulation material 33. The thermal insulation material 33 is an aerogel material, which can reduce the thermal conductivity and improve the thermal insulation effect. There are two first reinforcement plates 31. The two ends of the second reinforcement plate 32 are fixedly connected to the two first reinforcement plates 31 respectively. The thermal insulation material 33 is installed between the first reinforcement plate 31 and the second reinforcement plate 32.

[0023] By adopting the above technical solution, the No. 1 reinforcement plate 31, the No. 2 reinforcement plate 32 and the heat insulation material 33 can work together to reinforce the No. 1 door 1 and the No. 2 door 11, improve their stability, enhance the door's resistance to impact damage, and prevent malfunctions in the event of a fire.

[0024] Both Gate 1 and Gate 2 are fixed with symmetrically distributed connectors 13 on their outer sides.

[0025] By adopting the above technical solution, the No. 1 door 1 and the No. 2 door 11 can be installed in the door frame through the connector 13.

[0026] Both Gate 1 and Gate 2 are fixedly equipped with a No. 1 sealing strip 14 on their outer sides.

[0027] By adopting the above technical solution, the No. 1 sealing strip 14 can ensure that when the No. 1 door 1 and the No. 2 door 11 are closed, they are sealed with the door frame to prevent harmful gases from penetrating.

[0028] Both Gate 1 and Gate 2 are equipped with observation windows 15.

[0029] By adopting the above technical solution, the observation window 15 is made of fire-resistant and high-temperature resistant material, which facilitates observation of the situation.

[0030] A door lock 12 is installed on the outside of door number 2, number 11.

[0031] By adopting the above technical solution, the door lock 12 can close the gap between door 1 and door 11.

[0032] A second sealing strip 29 is fixedly installed on the side of the baffle 22 near the second door 11, and is symmetrically distributed.

[0033] By adopting the above technical solution, the second sealing strip 29 can improve the sealing performance between the baffle 22 and the door gap.

[0034] Reflective strips 16 are installed on the outside of both Gate 1 and Gate 2.

[0035] By adopting the above technical solution, the reflective strip 16 can conveniently provide a good warning effect.

[0036] Working principle: First, install Door 1 and Door 2 on the door frame, so that the baffle 22 is installed on one side of the escape passage. In case of fire, first close Door 1 and Door 2. Then pull the lever 24, causing it to disengage into the slot 28. At the same time, the movement of the lever 24 moves the fixing plate 26 within the circular groove 25. The movement of the fixing plate 26 compresses the compression spring 27. Then, the lever 24 can push the operating plate 23 to move. The movement of the operating plate 23 causes the two sliding bars 21 to slide within the external slide rail 2. The movement of the two sliding bars 21 moves the baffle 22 and Door 2. The sealing strip 29 moves, causing the baffle 22 to move to the gap between door 1 and door 21. Then the pull rod 24 can be released. At this time, the compression spring 27 rebounds and drives the fixing plate 26 to slide in the circular groove 25. The movement of the fixing plate 26 drives the pull rod 24 to move. At this time, the pull rod 24 will be inserted into another set of slots 28, thereby completing the adjustment of the baffle 22. By using the baffle 22 to block the gap between door 1 and door 21, it can effectively prevent smoke from spreading rapidly in the event of a fire, thereby protecting the relatively safe area, reducing the harm of smoke to people, and enhancing the evacuation safety inside the building.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
