Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a corrosion-resistant aluminum alloy door and window. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extrusion profiles as frames, stiles, and sash materials, which are called aluminum alloy doors and windows for short. Aluminum alloy doors and windows include those with aluminum alloy as the load-bearing members (members that bear and transfer their own weight and loads) and those combined with wood or plastic, which are called aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows for short. Aluminum is chemically active and easily reacts with oxygen, forming a dense aluminum oxide layer on its surface. The aluminum oxide has very stable properties and is not easily corroded. This layer of aluminum oxide acts as a protective layer to prevent the aluminum inside from further reacting or being corroded.

[0003] After retrieval, the Chinese patent discloses a corrosion-resistant aluminum alloy door and window with high wind resistance (authorization announcement number CN217681313U), which includes an outer window frame. Opposite sides of the middle of the outer window frame are respectively fixedly connected with a first sealing plate and a second sealing plate. Opposite sides of the first sealing plate and the second sealing plate are fixedly connected with two groups of wind-resistant connection devices. Each group of wind-resistant connection devices includes two parallel and fixedly installed stability-enhancing and resistance-reducing devices. Among them, the stability-enhancing and resistance-reducing device includes a slide rail frame, a runner, and a stress block. Although this patented technology is provided with a stability-enhancing and resistance-reducing device, it can effectively improve the stability of the first inner window frame, the second inner window frame, and the glass plate in strong wind weather, weaken the impact force of strong wind, and enhance the smoothness of the first inner window frame and the second inner window frame being pushed in strong wind weather, ensuring the safety of use and bringing a better application prospect.

[0004] However, there are still some drawbacks when the above device is actually used. The most obvious one is that there are gaps between the bottoms of the first inner window frame and the second inner window frame in the above aluminum alloy door and window and the slide rail frame. When there is a heavy rainstorm outdoors, rainwater may enter the first chute and the second chute through the gaps, resulting in the accumulation of rainwater that cannot be discharged. Furthermore, it will cause serious corrosion at the bottoms of the first inner window frame and the second inner window frame, thereby reducing the corrosion resistance and service life of the aluminum alloy door and window.

[0031] When there is a heavy rain weather outdoors, rainwater will enter the inside of the first U-shaped pipe 8 and the second U-shaped pipe 9 along the surfaces of the first opening and closing door panel 2 and the second opening and closing door panel 3. Subsequently, the rainwater in the first U-shaped pipe 8 and the second U-shaped pipe 9 will be discharged through the main drain pipes 6 and the secondary drain pipes 7. After the heavy rain weather ends, by pulling and sliding the first opening and closing door panel 2 and the second opening and closing door panel 3, the sliding balls 10 can be driven to slide in the corresponding U-shaped pipes, so as to accelerate the discharge of the rainwater in the first U-shaped pipe 8 and the second U-shaped pipe 9, reduce the phenomenon of rainwater retention, keep the inside of the first U-shaped pipe 8 and the second U-shaped pipe 9 dry, and further reduce the corrosion of the aluminum alloy by rainwater, thereby improving the corrosion resistance and service life of the aluminum alloy door and window.

[0037] Through the cooperation of the limit groove 11 and the rolling wheel 12, the sliding resistance between the first opening and closing door panel 2 and the second opening and closing door panel 3 can be reduced, making the opening and closing of the door panel more convenient.

[0038] Refer to Figure 1 , PVC plates 4 are respectively fixedly connected to the ends of the first opening and closing door panel 2 and the second opening and closing door panel 3 close to each other. The two PVC plates 4 are in contact with each other, reducing the infiltration of rainwater.

[0039] Refer to Figure 4 , the height of the first U-shaped tube 8 is greater than the height of the second U-shaped tube 9, which is beneficial to the rapid discharge of rainwater.

[0040] Refer to Figure 1, an inlaid handle is provided inside both the second opening and closing door panel 3 and the first opening and closing door panel 2 to facilitate the use of the first opening and closing door panel 2 and the second opening and closing door panel 3.

[0041] Working principle: When there is a heavy rainstorm outdoors, rainwater will enter the interiors of the first U-shaped pipe 8 and the second U-shaped pipe 9 along the surfaces of the first opening and closing door panel 2 and the second opening and closing door panel 3 respectively. Subsequently, the rainwater in the first U-shaped pipe 8 and the second U-shaped pipe 9 will be discharged through the main drain pipe 6 and the secondary drain pipe 7. After the heavy rainstorm ends, by pulling and sliding the first opening and closing door panel 2 and the second opening and closing door panel 3, the sliding ball 10 can be driven to slide in the corresponding U-shaped pipe, thereby accelerating the discharge of rainwater in the first U-shaped pipe 8 and the second U-shaped pipe 9, reducing the phenomenon of rainwater retention, keeping the interiors of the first U-shaped pipe 8 and the second U-shaped pipe 9 dry, and further reducing the corrosion of aluminum alloy by rainwater. Thus, the corrosion resistance and service life of the aluminum alloy doors and windows can be improved. Through the elastic force of the spring 14, the push plate 15 can be pushed to move in the installation groove 13, so that the clamping groove 17 can be engaged with the clamping plate 5, and at the same time, the insertion rod 16 can be driven to insert into the corresponding insertion hole 18, thereby fixing the first opening and closing door panel 2 or the second opening and closing door panel 3 to the door frame 1, reducing the movement of the sliding first opening and closing door panel 2 and the second opening and closing door panel 3 caused by strong wind weather usually. Through the setting of the moving plate and the limiting groove, it is convenient to pull the push plate 15, and thus it is convenient to unlock the locking mechanism.

[0042] The above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
