Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic coated window frames, in particular to an aluminum-plastic coated window frame structure connected by buckles with seamless welding of external aluminum. Background Art

[0002] At present, most aluminum-clad plastic windows on the market are based on plastic windows. On the outside of the frame and sash, the aluminum alloy profiles are wrapped on the outside of the UPVC profiles through the double cantilever hooks of the aluminum alloy profiles. Then the structure of the aluminum-clad plastic window is realized by changing the form of the rubber strips and the overlap position. The deformed component in this process is the aluminum alloy profile. This structure has the following problems and shortcomings: First, due to the large difference in the thermal expansion coefficients of the UPVC profile and the aluminum alloy profile, after the outdoor ambient temperature changes drastically, stress and displacement will be generated between the two materials, which will affect the structural strength of the window; secondly, because the installation hooks of the aluminum alloy profiles are located on the cantilever side of the two ends of the profile, due to the structural integrity requirements, etc., the aluminum alloy profile cannot be installed after being welded as a whole, and the gap at the connection position of the aluminum alloy profile is large and there is a height difference; finally, the cantilever of the aluminum alloy profile as a deformable component may produce irreversible deformation, resulting in dimensional errors.
