Description

Technical Field

[0001] The utility model relates to the technical field of flame-retardant doors and windows, in particular to a flame-retardant door and window structure. Background Art

[0002] Doors and windows are divided into enclosure components or partition components according to their location. They have different design requirements and must have functions such as thermal insulation, heat insulation, sound insulation, waterproofing, and fire prevention. The new requirement is energy saving. In cold areas, the heat lost through gaps in doors and windows accounts for about 25% of the total heating heat consumption. The airtightness requirement of doors and windows is an important part of energy-saving design. At the same time, since doors and windows are important components of the building envelope system, their shape, size, proportion, arrangement, color, and shape will have a great impact on the overall shape of the building.

[0003] Existing doors and windows are usually made of aluminum alloy, which can only rely on their own material properties to resist flames, and the fire protection method is relatively simple. Some doors and windows adopt a method of setting a cavity in the frame and filling the cavity with flame retardants for fire protection, but due to the metal frame, it is difficult for the flame retardant to seep out, and the effect of the flame retardant cannot be exerted when a fire occurs. Moreover, the existing flame-retardant doors and windows are generally integrated, which is not convenient to open and close the flame-retardant tightly flame-retardant doors and windows, and the flexibility is low. Therefore, in response to the above problems, this application proposes a flame-retardant door and window structure. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A flame retardant door and window structure in this embodiment includes a fixed frame 1, and a sealing adjustment mechanism is arranged on the inner side of the fixed frame 1.

[0024] In embodiment 1, the sealing adjustment mechanism includes a flame retardant pad 2 fixedly installed on the inner side of the fixed frame 1. The flame retardant pad 2 is two layers of silicone sealing strip and ceramic fiber. The flame retardant pad 2 covers the inner side of the fixed frame 1, which helps the flame retardant pad 2 to seal. The left inner wall of the fixed frame 1 is hinged with a door and window frame 3, and a glass window 4 is fixedly installed inside the door and window frame 3.

[0025] Among them, the glass window 4 is a transparent explosion-proof glass, and the glass window 4 is bonded to the door and window frame 3 by a flame-retardant composite adhesive, which helps to install and fix, and improve the strength of the glass window 4. A handle frame 5 is fixedly installed on the front of the door and window frame 3, and an installation box 6 is fixedly installed on the front of the door and window frame 3.

[0026] In this embodiment, a fixed shaft 7 is fixedly installed inside the installation box 6, and a return spring 8 fixedly connected to the installation box 6 is movably connected to the outer side of the fixed shaft 7. A movable plate 9 is fixedly installed on one side of the return spring 8. A movable groove is opened inside the movable plate 9. The movable plate 9 is movably connected to the fixed shaft 7 through the movable groove, which helps to limit the movable plate 9.

[0027] Among them, a limit block 10 slidably connected to the installation box 6 is fixedly installed on the top of the movable plate 9, and a slide groove is opened on the inner top wall of the installation box 6. The limit block 10 is slidably connected to the installation box 6 through the slide groove, which helps to fix the installation box 6.

[0028] In the second embodiment, a limit clamping assembly is arranged inside the installation box 6, and the limit clamping assembly includes a limit rod 11 fixedly installed inside the installation box 6 and slidably connected to the movable plate 9, a pull ring 12 is fixedly installed at the bottom of the movable plate 9, and a limit pin 13 extending to the outside of the installation box 6 is fixedly installed on the side of the movable plate 9 away from the fixed axis 7.

[0029] Among them, two through slots are opened on one side of the installation box 6, and the limit pin 13 is slidably connected with the installation box 6 through the through slot, which helps the limit pin 13 to be movably connected. The outer side of the limit pin 13 is clamped with a socket 14 fixedly connected to the fixed frame 1, and the inside of the socket 14 is provided with a slot. The limit pin 13 is clamped with the socket 14 through the slot, which helps the limit pin 13 to clamp, fix and disassemble the socket 14.

[0030] It should be noted that the flame-retardant door and window structure, through the sealing adjustment mechanism, uses the pull ring 12, the movable plate 9 and the reset spring 8 to drive the limit pin 13 to telescopically move. The limit pin 13 is inserted into the interior of the socket 14 to install and fix the door and window frame 3 and the fixed frame 1, or the limit pin 13 can be driven to detach from the interior of the socket 14, so that the door and window frame 3 and the fixed frame 1 can be disassembled, which is convenient for quick opening and closing. The flame-retardant pad 2 can be used to seal both sides of the door and window to avoid air permeability that increases the combustion speed, and effective flame retardancy and fire prevention can be performed, which greatly improves the flexibility and practicality of the device.

[0031] The working principle of the above embodiment is:

[0032] When using the flame-retardant door and window structure, the pull ring 12 is first pulled, and the pull ring 12 drives the movable plate 9 to move. The movable plate 9 slides on the outside of the limit rod 11, and the movable plate 9 is limited by the limit block 10 and the limit rod 11, so that the movable plate 9 moves vertically and smoothly, which facilitates the movable plate 9 to smoothly drive the limit pin 13 to move and shrink, and then the door and window frame 3 can be pushed and rotated together with the glass window 4 on the inner side of the fixed frame 1 until the door and window frame 3 is buckled on the inner side of the fixed frame 1, at which time the installation box 6 corresponds to the position of the card seat 14, and then the pull ring 12 can be released;

[0033] At this time, the reset spring 8 starts to reset automatically, and the reset spring 8 drives the movable plate 9 to move. The movable plate 9 moves smoothly through the limit block 10 and the limit rod 11, thereby driving the limit pin 13 to be inserted into the interior of the holder 14 again, so as to install and fix the door and window frame 3 and the fixed frame 1. Similarly, by pulling the pull ring 12, under the action of the reset spring 8, the limit pin 13 can be driven to disengage from the interior of the holder 14, so that the limit fixation is no longer required, which is convenient for rapid opening and closing. By using the flame retardant pad 2, both sides of the door and window can be sealed to avoid air permeability increasing the combustion speed, and effective flame retardancy and fire prevention can be performed, which greatly improves the flexibility and practicality of the device.
