[0019] Please refer to Figures 1 - 3, an aluminum alloy door and window sealing structure, including an aluminum alloy window frame 1 and an aluminum alloy window 11. The aluminum alloy window 11 is installed inside the aluminum alloy window frame 1 through hinges. A first card slot is provided on the front side of the aluminum alloy window frame 1, and a second card slot is provided on the rear side of the outer frame of the aluminum alloy window 11. The first card slot corresponds to the second card slot. A sealing component is placed between the aluminum alloy window frame 1 and the aluminum alloy window 11. The sealing component includes a first sealing strip 21 and a second sealing strip 23. A first card strip 2 is fixedly arranged on the rear side of the first sealing strip 21, and a second card strip 22 is fixedly arranged on the front side of the second sealing strip 23. Semi-circular grooves are evenly opened on the front side of the first sealing strip 21, and semi-circular strips 24 are evenly fixedly arranged on the rear side of the second sealing strip 23. A reinforcing strip 26 and an outward-turning strip 25 are fixedly arranged on the left side of the second sealing strip 23. The outward-turning strip 25 is located behind the reinforcing strip 26, and the rear side of the reinforcing strip 26 is fixedly arranged on the front side of the outward-turning strip 25. When the first card strip 2 is clamped in the first card slot of the aluminum alloy window frame 1, the first sealing strip 21 can be fixed on the aluminum alloy window frame 1. When the second card strip 22 is clamped in the second card slot of the aluminum alloy window 11, the second sealing strip 23 can be fixed on the aluminum alloy window 11. When the aluminum alloy window frame 1 and the aluminum alloy window 11 are combined, the second sealing strip 23 and the first sealing strip 21 are mutually extruded and fitted to initially seal the connection gap between the aluminum alloy window frame 1 and the aluminum alloy window 11. At the same time, the semi-circular strip 24 is clamped in the semi-circular groove of the first sealing strip 21, thereby strengthening the sealing effect of the first sealing strip 21 and the second sealing strip 23, and secondarily sealing the connection gap between the aluminum alloy window frame 1 and the aluminum alloy window 11. Then, the rear side of the outward-turning strip 25 is fitted to the front side of the aluminum alloy window frame 1 to perform a third sealing of the connection gap between the aluminum alloy window frame 1 and the aluminum alloy window 11. The second sealing strip 23 and the first sealing strip 21 are of a hollow design. The semi-circular strip 24 is clamped in the semi-circular groove of the first sealing strip 21. The first sealing strip 21 and the first card strip 2 are of an integrally formed design. The second sealing strip 23, the semi-circular strip 24, the second card strip 22, the outward-turning strip 25, and the reinforcing strip 26 are of an integrally formed design. The reinforcing strip 26 can improve the supporting force of the outward-turning strip 25, thereby improving the fitting stability between the outward-turning strip 25 and the aluminum alloy window frame 1, so as to ensure the sealing effect of the sealing component. The first card strip 2, the first sealing strip 21, the second card strip 22, the second sealing strip 23, the semi-circular strip 24, the outward-turning strip 25, and the reinforcing strip 26 are all made of silica gel. The first card strip 2 is clamped in the first card slot of the aluminum alloy window frame 1, the second card strip 22 is clamped in the second card slot of the aluminum alloy window 11, the opposite sides of the first sealing strip 21 and the second sealing strip 23 are mutually fitted, and the rear side of the outward-turning strip 25 is fitted to the front side of the aluminum alloy window frame 1.

[0020] Working principle: When the first clamping strip 2 is clamped in the first clamping groove of the aluminum alloy window frame 1, the first sealing strip 21 can be fixed on the aluminum alloy window frame 1. When the second clamping strip 22 is clamped in the second clamping groove of the aluminum alloy window 11, the second sealing strip 23 can be fixed on the aluminum alloy window 11. When the aluminum alloy window frame 1 and the aluminum alloy window 11 are combined, the second sealing strip 23 and the first sealing strip 21 are pressed and fitted against each other, thereby initially sealing the connection gap between the aluminum alloy window frame 1 and the aluminum alloy window 11. At the same time, the semicircular strip 24 is clamped in the first clamping groove of the aluminum alloy window frame 1. A semicircular groove of a sealing strip 21 is formed, thereby reinforcing the sealing effect of the first sealing strip 21 and the second sealing strip 23, so as to perform a secondary sealing on the connection gap between the aluminum alloy window frame 1 and the aluminum alloy window 11, and then the rear side of the outward-turned strip 25 is fitted with the front side of the aluminum alloy window frame 1 to perform a third sealing on the connection gap between the aluminum alloy window frame 1 and the aluminum alloy window 11. The reinforcing strip 26 can increase the supporting force of the outward-turned strip 25, thereby improving the fitting stability between the outward-turned strip 25 and the aluminum alloy window frame 1, thereby ensuring the sealing effect of the sealed component.
