Description

Technical Field

[0001] This utility model relates to the field of fire door technology, and more specifically, to a multi-layer composite heat-insulating fire door. Background Technology

[0002] In existing technologies, the fire resistance performance of multi-layer composite insulated fire doors mainly relies on the composite material structure of the door body and the sealing performance of the doors and windows. However, in actual use, when a fire occurs, the design of existing fire doors makes it difficult to complete the fire protection process.

[0003] In the design of multi-layer composite insulated fire doors, mechanical devices such as fixing rods and fixing sleeves are usually used to fix the window body to ensure that it does not loosen or fall off during normal use. These fixing rods and fixing sleeves are to maintain the stability and fire resistance of the window body, so that the window body can be effectively connected to other parts of the door body. However, in actual use, the existing fire door design makes the process of releasing the fixing rods and fixing sleeves very cumbersome and inconvenient.

[0004] In addition to fireproofing and securing functions, the securing performance of the window is equally important, especially the securing of the window itself. When the fire door is closed, the securing of the window must be able to effectively prevent smoke and flames from entering and ensure the integrity of the fire door. However, existing fire door designs also have certain problems in the window securing process. Utility Model Content

[0032] Please see Figures 1-7 A multi-layer composite heat-insulating fire door includes an outer frame 1, on which a heat-insulating component is provided. The heat-insulating component includes hinges 2 and a main door 3. The hinges 2 are provided on the outer frame 1, and multiple hinges 2 are provided. The main door 3 is provided at one end of some of the hinges 2. A side door 4 is provided on some of the hinges 2. The main door 3 is provided with a handle 5. Both the main door 3 and the side door 4 are provided with a frame 6 inside. The main door 3 is provided with a fixing component, which includes a fixing rod 7 and a window 8. The fixing rod 7 is provided on the main door 3, and the window 8 is slidably connected to the fixing rod 7. The fixing rod 7 passes through the window 8 and is detachably provided with a fixing sleeve 9.

[0033] Cooling plate 10 is provided on frame 6.

[0034] Insulation plates 11 are evenly distributed on the frame 6.

[0035] A movable plate 12 is slidably provided on the fixed sleeve 9, a movable rod 13 is provided on the movable plate 12, and a movable block 14 is provided at one end of the movable rod 13.

[0036] The other end of the moving rod 13 is provided with an abutment block 15, a spring 16 is provided between the moving plate 12 and the fixed sleeve 9, and a rotating ring 17 is rotatably provided on the fixed sleeve 9.

[0037] The rotating ring 17 has a through hole 18 that is adapted to the moving block 14. The rotating ring 17 also has an outlet groove 19 that is connected to the through hole 18.

[0038] In this embodiment, the outer frame 1 is attached to a suitable position on the wall and fixed with external bolts. During use, the main door 3 is opened using the handle 5, and the side door 4 and hinge 2 are used to complete the opening process. The heat insulation board 11, frame 6, and cooling board 10 provide fire protection. To quickly fix the window 8, the fixing sleeve 9 and fixing rod 7 are used. When the window 8 needs to be removed, the moving plate 12 is moved along... The fixed sleeve 9 slides, compressing the spring 16 between the moving plate 12 and the fixed sleeve 9 during the sliding movement. When the moving plate 12 moves, it moves the moving rod 13, the moving block 14, and the abutting block 15 on it, so that the moving block 14 passes through the through hole 18 on the rotating ring 17. Then the rotating ring 17 is rotated, so that the moving rod 13 rotates along the slot 19 on the rotating ring 17 during the rotation. When it is rotated to the point that one end of the moving rod 13 abuts against the rotating ring 17, the moving rod 13 is fixed.

[0039] Please see Figures 3-5 As a further embodiment of the overall equipment: a locking component is provided on the fixed sleeve 9. The locking component includes a control sleeve 20 and a control block 21. The control sleeve 20 is rotatably connected to the fixed sleeve 9, and the control block 21 is slidably connected to the fixed sleeve 9. A rotating block 22 is provided on the control block 21.

[0040] The control sleeve 20 has a control groove 23, which is adapted to the rotating block 22. The abutting block 15 abuts against the control block 21. The fixing rod 7 has a fixing groove 24, which is adapted to the control block 21.

[0041] More specifically, when the movable plate 12 moves, the movable rod 13 is moved, causing one end of the movable rod 13 to be removed from the control sleeve 20, thereby releasing the fixation of the control sleeve 20. Then, the control sleeve 20 is rotated along the fixed sleeve 9, causing the rotating block 22 on it to move along the control groove 23. During the movement, the control block 21 on it is moved, causing it to be removed from the fixing groove 24 of the fixed rod 7, thereby releasing the fixation between the fixed rod 7 and the fixed sleeve 9. At this time, the fixed sleeve 9 can be removed from the fixed rod 7, releasing the fixation of the window 8. Then, the window 8 is slid out from the fixed rod 7. When it is necessary to fix the window 8, the above operation is repeated in reverse.

[0042] In summary, during use or operation of the entire equipment: the outer frame 1 is fitted to a suitable position on the wall and fixed with external bolts. When in use, the main door 3 is opened using the handle 5, and the side door 4 and hinge 2 are used to complete the opening process. During use, the heat insulation board 11, frame 6, and cooling board 10 complete the fireproofing process, thus achieving the purpose of fire prevention. Furthermore, to quickly fix the window 8, the fixing sleeve 9 and fixing rod 7 are used. When it is necessary to remove the window 8, the moving... The plate 12 slides along the fixed sleeve 9, compressing the spring 16 between the moving plate 12 and the fixed sleeve 9 during the sliding movement. As the moving plate 12 moves, it moves the moving rod 13, the moving block 14, and the abutting block 15, causing the moving block 14 to pass through the through hole 18 on the rotating ring 17. Then, the rotating ring 17 is rotated, causing the moving rod 13 to rotate along the slot 19 on the rotating ring 17. When the moving rod 13 is rotated to the point where one end of it abuts against the rotating ring 17, the moving rod 13 is fixed.

[0043] When the movable plate 12 moves, the movable rod 13 is moved, thereby removing one end of the movable rod 13 from the control sleeve 20, thus releasing the fixation of the control sleeve 20. Then, the control sleeve 20 is rotated along the fixed sleeve 9, so that the rotating block 22 on it moves along the control groove 23 during the rotation, so that the control block 21 on it moves and is removed from the fixing groove 24 of the fixed rod 7, thereby releasing the fixation between the fixed rod 7 and the fixed sleeve 9. At this time, the fixed sleeve 9 can be removed from the fixed rod 7, releasing the fixation of the window 8. Then, the window 8 is slid out from the fixed rod 7. When it is necessary to fix the window 8, the above operation is repeated in reverse.

[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
