Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire door equipment, and in particular to a high-security fire door. Background Technology
[0002] Fire doors are doors with fire-resistant functions. Their main purpose is to prevent the spread of fire and protect people and property during a fire. Fire doors are usually made of special fire-resistant materials, such as steel, non-combustible materials, or wood containing fire retardants. These materials have high fire resistance and can withstand high temperatures for a certain period of time without easily burning.
[0003] Chinese Patent CN220434583U discloses a steel insulated fire door. The protective frame is hinged to the fire door body. A moving device is fitted inside the fire door body. The moving device includes a support rod, which is fitted inside the fire door body. Telescopic rods are fitted to both sides of the support rod, and a protective plate is fitted to one end of each telescopic rod. This steel insulated fire door, by setting up a protective frame and sealing plates, allows the protective plate to compress a spring inside the fire door body when pushed by hot air. This, in turn, pushes the corresponding support block, two moving plates, a baffle, and a slider to move relative to each other within a groove. This allows the sealing strip to be engaged in the sealing groove, enabling the device to automatically seal the gap between the fire door body and the protective frame. This prevents inadequate sealing from affecting smoke blocking, ensuring the sealing effect of the device.
[0004] However, the device still has shortcomings: in the event of a fire or other emergencies, people become very panicked or anxious, so the limited space during the escape process also affects the speed of people's escape. The device cannot completely retract the fire door, so the space available for people to escape is also relatively limited. Utility Model Content
[0005] The purpose of this invention is to address the problem in the prior art that fire doors cannot be fully retracted, and to propose a high-security fire door.
[0006] The technical solution of this utility model: a high-security fireproof door, comprising:

[0031] Example 1
[0032] like Figures 1-3 As shown, the present invention proposes a high-security fire door, which includes a wall 2, a connecting plate 11, a guide assembly, and a fire door body 3.
[0033] A mounting bracket 1 is provided on the wall 2, and a slide rail 5 is provided on the mounting bracket 1. There are two sets of slide rails 5, and one end of the slide rail 5 is an inclined rail. Two sets of connecting plates 11 are provided, and the two sets of connecting plates 11 are slidably mounted on the mounting bracket 1. A sliding component for driving the sliding of the connecting plates 11 is provided on the mounting bracket 1. A guide component is provided on the connecting plate 11 and slidably connected to the slide rail 5. The guide component includes a first connecting post 12: the first connecting post 12 is connected to the connecting plate 11 and slidably mounted on the slide rail 5. The fire door body 3 is connected to the guide component and extends into the wall 2. A cavity for accommodating the fire door body 3 is provided on the wall 2.
[0034] like Figure 3 As shown, the sliding assembly includes a rack 10, a drive device, a mounting post 8, and a gear 9. The rack 10 is connected to two sets of connecting plates 11, one set of connecting plates 11 being located at one end of the rack 10, and the other set of connecting plates 11 being located at the edge of the other end of the rack 10. The drive device is mounted on the mounting frame 1, and the drive device is selected as a motor 7. Two sets of support frames 4 are provided on the mounting frame 1, and the motor 7 is located on one side of one set of support frames 4. The mounting post 8 is rotatably mounted between the two sets of support frames 4 and connected to the output shaft of the motor 7. The gear 9 is mounted on the mounting post 8 and meshes with the rack 10.
[0035] Example 2
[0036] The present invention proposes a high-security fire door, and compared with Embodiment 1, this embodiment also describes in detail the structure of the guide assembly.
[0037] like Figures 3-4 As shown, the fire door body 3 is provided with a connecting frame 6, and multiple sets of connecting frames 6 are provided. The connecting frame 6 is an L-shaped frame. The guide assembly also includes a mounting block 13, rollers 14, a second connecting column 16, and guide rollers 15. The mounting block 13 is connected to the first connecting column 12. The rollers 14 are rotatably disposed on both sides of the mounting block 13 and are slidably connected to the slide rail 5. The second connecting column 16 is disposed at the bottom of the mounting block 13 and is rotatably connected to the connecting frame 6. Two sets of guide rollers 15 are provided. The two sets of guide rollers 15 are rotatably disposed below the mounting block 13 and are slidably connected to the slide rail 5. The second connecting column 16 is located between the two sets of guide rollers 15. Through the coordinated use of the connecting plate 11, the sliding assembly, and the guide assembly, the squeezing and blockage caused by the opening of the fire door body 3 during the evacuation of people can be reduced, and people can be prevented from being obstructed during the evacuation process.
[0038] In summary, when this utility model is in use and an emergency requires the evacuation of people, the motor 7 is turned on, which drives the mounting column 8 and gear 9 to rotate. Since gear 9 meshes with rack 10, it drives rack 10 and connecting plate 11 to move. The movement of connecting plate 11 drives first connecting column 12 to slide on slide rail 5. The sliding of first connecting column 12 drives mounting block 13 and roller 14 to slide on slide rail 5. Since one end of slide rail 5 is an inclined rail, the movement of first connecting column 12, mounting block 13 and roller 14 will simultaneously drive guide roller 15 to move. When guide roller 15 moves, it can engage with the turning point of slide rail 5, so that the connecting frame 6 and fire door body 3 can move without obstruction. When rack 10 moves towards the wall 2, it can retract the fire door body 3 completely into the wall 2, freeing up extra space, increasing the width of the evacuation passage, and thus improving the efficiency and speed of personnel evacuation.
[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
