Description

Technical Field

[0001] The utility model relates to the technical field of fireproof windows, and more specifically to a thermal insulation fireproof window with a sealing structure and a steel lining. Background Art

[0002] Fireproof windows, also known as smokeproof windows, are windows used to maintain the fire resistance integrity of fire escapes and provide escape routes. Their purpose is to ensure that people escaping in the fire escape are protected from the threat of fire within a reasonable period of time (usually the escape time), including blocking thick smoke and heat.

[0003] Based on the above, the inventors found that when a fire occurs, the existing fireproof windows will be deformed to a certain extent due to the high temperature, which makes the sealing performance of the door deteriorate. High-temperature smoke penetrates through the aluminum alloy doors and windows and causes harm to the human body after inhalation. At the same time, in order to increase the sealing performance, the existing fireproof windows will install rubber sealing strips on the window body. The rubber sealing strips and the window are mostly fixedly connected by gluing. After long-term use, the rubber sealing strips will become loosely adhered and there will be a gap between the window, which will affect the sealing performance of the window. Therefore, in view of this, the existing structure is studied and improved, and a thermal insulation fireproof window with a sealing structure and a steel lining is provided, in order to achieve a more practical purpose.

At the same time, a steel lining is added inside the frame to improve the overall strength of the frame, solve the problem of certain deformation of the frame after being subjected to high temperature, and improve the stability and sealing of the overall structure.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0009] The sealing mechanism includes a plurality of compression springs fixed in the return groove and a sealing rubber sleeve fixed to one side of the extension frame. One end of the compression spring is fixedly connected to a resist plate. The compression spring and the resist plate are both arranged on the inner side of the sealing rubber sleeve.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) In this solution, by setting up a compression spring and a stop plate, after the window leaf is closed, the window frame squeezes the stop plate, causing the compression spring to be compressed and deformed. The rebound force generated by the deformation of the compression spring, with the cooperation of the stop plate, makes the outer surface of the sealing rubber sleeve closely contact with the surface of the window frame, thereby achieving a certain sealing effect. At the same time, under the joint action of the sealing strip 1 and the sealing strip 2, the sealing performance of the overall structure is further improved.

[0019] (2) In this scheme, the overall strength of the steel lining is improved through the arrangement of the steel lining and the coordination of the internal support plate, reinforcing ribs and sealing plate. The steel lining is located inside the frame and provides a certain support to the inside of the frame, making the overall structure more stable and avoiding the phenomenon of certain deformation of the frame after being subjected to high temperature, thereby improving the stability and sealing of the overall structure.
