Description

Technical Field

[0001] The utility model relates to the technical field of door and window conversion frames, in particular to a door and window conversion frame. Background Art

[0002] Plastic-steel windows are one of the most commonly used window types in modern buildings after wooden, iron and aluminum alloy windows. The frames of plastic-steel windows are made of polyvinyl chloride resin as the main raw material, with a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., and are extruded into molded materials. At present, all plastic-steel conversion frames on the market have the disadvantages of insufficient frame and sash overlap and poor sealing. At the same time, most of the mass-produced plastic-steel conversion frames have obvious gaps at the joints between the conversion frame and the original doors and windows, which affects the appearance of the doors and windows.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN217841313U in the prior art discloses a plastic-steel door and window conversion frame, including a window body, a window sash located on one side of the window body, and a frame located between the window body and the window sash, the window body including a first sound insulation groove arranged at one end inside the window body, a vacuum groove arranged at the middle position inside the window body, and a second sound insulation groove arranged inside the window body away from one end of the first sound insulation groove.

[0004] Although the above-mentioned existing technical solutions ensure the aesthetics of the doors and windows after installation, the sealing strips on both sides of the window body cannot ensure complete sealing regardless of whether they are manually glued or formed and pressed. Especially after a period of use, if rainwater penetrates into the profile through the sealing strips and accumulates inside the profile, the profile will rust over time, which will affect the stability of the profile structure.
