[0002] In modern architecture, external windows are widely used because they do not occupy indoor space and have good ventilation performance. However, external windows have certain deficiencies in terms of safety, sealing performance, and mosquito prevention effect. Especially in high - rise buildings, the installation and use of external windows need to be more cautious to ensure safety and functionality. With the development of technology, some solutions have emerged in the market to improve the performance and user experience of external windows. For example, the Chinese utility model patent with the patent number CN211818946U - an external casement window with a three - seal drainage prevention system, discloses a solution for setting a three - seal waterproof structure between the window frame and the window sash. However, since the sealing structures are all set between the window frame and the window sash, the designed widths of the window frame and the window sash are relatively large.

[0028] It should be noted that: similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] Currently, while the window products on the market meet the basic functions, there are often problems of insufficient ornamental value, sealing performance, and functionality. To solve this problem, the present application provides a three - seal structure for a broken - bridge aluminum alloy outward - opening window.

[0030] Please refer to Figures 1 to 3 , a three - seal structure for a broken - bridge aluminum alloy outward - opening window. The outward - opening window at least includes a window frame 1 and a window sash 2 hinged in the window frame 1. The window frame 1 includes a conversion frame 11, and the window sash 2 is hinged in the conversion frame 11;

[0031] The conversion frame 11 includes a first frame body 111 and a second frame body 112 arranged horizontally at intervals. The window sash 2 includes a first window sash profile 21 and a second window sash profile 22 arranged horizontally at intervals. A window frame heat insulation strip 113 is arranged between the first frame body 111 and the second frame body 112, and a window sash heat insulation strip 23 is arranged between the first window sash profile 21 and the second window sash profile 22;

[0032] The first frame body 111 contacts the first sash profile 21 to form a first sealing structure 33; the first overlapping point 114 and the second overlapping point 24 extending towards each other are respectively arranged on the window frame heat insulation strip 113 and the sash heat insulation strip 23, and the first overlapping point 114 contacts the second overlapping point 24 to form a second sealing structure 34; the second frame body 112 contacts the second sash profile 22 to form a third sealing structure 35.

[0033] Among them, the sash 2 hinged in the window frame 1 opens outwards, and the conversion frame 11 is arranged in the middle of the outer frame profile of the window frame 1 and has a first frame body 111 and a second frame body 112 arranged at a horizontal interval. In order to achieve a good heat preservation effect, a window frame heat insulation strip 113 is arranged between the first frame body 111 and the second frame body 112. Two window frame heat insulation strips 113 are arranged at intervals in the vertical direction to form a heat preservation cavity, and heat preservation materials can be filled in the heat preservation cavity, which can not only achieve heat preservation but also prevent air or moisture from entering the window frame 1. The conversion frame 11 is set to hinge the sash 2, that is, the sash 2 is hinged between the first frame body 111 and the second frame body 112. Such a design can ensure the stability and durability of the sash 2 when it is opened and closed, and can also avoid damage to the outer frame.

[0034] Among them, the structure of the conversion frame 11 can be stepped, and it has multiple contact points with the sash 2 at different positions in the vertical direction, so as to form a stepped sealing structure and achieve good waterproof performance. The sash 2 has a first sash profile 21 and a second sash profile 22 arranged at a horizontal interval, and a sash heat insulation strip 23 is arranged between the first sash profile 21 and the second sash profile 22. Two sash heat insulation strips 23 are arranged at intervals in the vertical direction to form a heat preservation cavity, and heat preservation materials can be filled in the middle, which can not only achieve a good heat preservation effect but also prevent air or moisture from entering the sash 2.

[0035] Among them, the first frame body 111 and the first sash profile 21 are arranged near the indoor side, the second frame body 112 and the second sash profile 22 are arranged near the outdoor side. The first frame body 111 contacts the first sash profile 21 to form a first sealing structure 33, which can seal the gap between the window frame 1 and the sash 2 and prevent the penetration of air and moisture. A first sealing strip 3 can be arranged between the first frame body 111 and the first sash profile 21 to form the first sealing structure 33, and the first sealing strip 3 can be made of EPDM material. The first overlapping point 114 is arranged on the window frame heat insulation strip 113 and extends towards the sash heat insulation strip 23. The second overlapping point 24 is arranged on the sash heat insulation strip 23 and extends towards the window frame heat insulation strip 113 so as to be in contact with the first overlapping point 114 to form a second sealing structure 34. When the sash 2 is opened, the second sealing structure 34 can seal the gap when the sash 2 is opened, further enhancing the sealing effect. The second frame body 112 contacts the second sash profile 22 to form a third sealing structure 35, providing an additional sealing layer to further prevent the entry of external air and moisture. Among them, a second sealing strip 4 can be arranged between the second frame body 112 and the second sash profile 22 to form an airtight structure.

[0036] Among them, there is a height difference in the vertical direction between the first sealing structure 33, the second sealing structure 34 and the third sealing structure 35, forming a stepped sealing structure, which improves the overall watertightness of the outward-opening window. Compared with the prior art, the solution of the present application has significant advantages. First, by arranging three sealing structures between the window frame 1 and the sash 2, the sealing performance and heat insulation performance are effectively improved. Second, by reasonably designing the structures of the window frame 1 and the sash 2, the increase in the design width is avoided, thereby simplifying the assembly process and enhancing the aesthetics and consistency of the outward-opening window.

[0037] Furthermore, a first cavity 31 is formed between the first sealing structure 33 and the second sealing structure 34, and the first cavity 31 is used for heat preservation. A second cavity 32 is formed between the second sealing structure 34 and the third sealing structure 35, and the second cavity 32 is used for drainage.

[0038] Among them, since there are multiple contact points between the conversion frame 11 and the window sash 2, and the first sealing structure 33, the second sealing structure 34, and the third sealing structure 35 are distributed in a stepped manner, a first cavity 31 for heat preservation can be formed between the first sealing structure 33 and the second sealing structure 34, and a second cavity 32 for drainage can be formed between the second sealing structure 34 and the third sealing structure 35. A first sealing strip 3 is arranged in the first cavity 31, which is used to seal the gap between the conversion frame 11 and the window sash 2 and seal the gap when the window sash 2 is opened. A second sealing strip 4 is arranged in the second cavity 32, which is used to seal the connection gap between the conversion frame 11 and the window frame 1 on the outdoor side. Through the setting of these two cavities, not only the heat preservation performance of the window can be improved, but also the drainage can be effectively carried out to prevent water from seeping into the room, thereby enhancing the overall performance and use experience of the window.

[0039] Further, a first sealing strip 3 is arranged in the first cavity 31. The first sealing strip 3 is connected to the first frame body 111 and the first window sash profile 21, which is used to seal the gap between the conversion frame 11 and the window sash 2. The first sealing strip 3 is also connected to the first overlapping point 114 and the second overlapping point 24, which is used to seal the gap when the window sash 2 is opened.

[0040] Among them, the first sealing strip 3 plays a sealing role in the first cavity 31. By connecting with the first frame body 111 and the first window sash profile 21, it can effectively seal the gap between the conversion frame 11 and the window sash 2, preventing the penetration of air and moisture. At the same time, the first sealing strip 3 is also connected to the first overlapping point 114 and the second overlapping point 24. By designing the first sealing strip 3 with multiple-point contact, the number of sealing contact points between the window sash 2 and the window frame 1 is increased, providing a good sealing effect. Cooperating with the second sealing strip 4 realizes a triple-sealing function.

[0041] In some specific embodiments, the first sealing strip 3 is arranged in the first cavity 31 and connected to the first frame body 111 and the first window sash profile 21, forming an effective sealing structure. This sealing structure can not only seal the gap between the conversion frame 11 and the window sash 2 when the window sash 2 is closed, but also maintain the sealing effect of the window sash itself through the connection with the first overlapping point 114 and the second overlapping point 24 when the window sash 2 is opened. This design ensures the sealing performance of the window in different states, prevents the penetration of air and moisture, and significantly improves the service life and performance of the window.

[0042] Further, a second sealing strip 4 is arranged in the second cavity 32. The second sealing strip 4 is connected to the second frame body 112 and the second window sash profile 22, which is used to seal the connection gap between the conversion frame 11 and the window sash 2 on the outdoor side.

[0043] Among them, the second sealing strip 4 arranged in the second cavity 32 can effectively seal the connection gap between the conversion frame 11 and the window sash 2 near the outdoor side through the connection with the second frame body 112 and the second window sash profile 22. This design further improves the sealing performance of the window by adding a sealing barrier, especially preventing external air and moisture from entering the room through the connection gap, thereby improving the overall sealing and waterproof performance of the window.

[0044] Furthermore, the first overlapping point 114 and the second overlapping point 24 are respectively located in the middle of the window frame heat insulation strip 113 and the window sash heat insulation strip 23.

[0045] Among them, by respectively arranging the first overlapping point 114 and the second overlapping point 24 in the middle of the window frame heat insulation strip 113 and the window sash heat insulation strip 23, it can be ensured that when the window sash 2 is closed, the overlapping points can better contact and seal with the first sealing strip 3, thereby improving the overall sealing performance. This design can not only effectively prevent the penetration of air and moisture, but also enhance the heat insulation effect of the window, improving the living comfort and energy-saving effect.

[0046] Furthermore, the window frame 1 further includes an outer frame outer profile 12, and a screen window structure 5 is also arranged on the side of the conversion frame 11 close to the outdoor. The screen window structure 5 is connected to the outer frame outer profile 12; the screen window structure 5 includes a screen window frame 51 connected to the outer frame outer profile 12, and a screen window profile 52 hinged to the screen window frame 51. The side of the screen window profile 52 close to the outdoor is flush with the outer frame outer profile 12.

[0047] Among them, in the technical solution of the present application, an outer frame outer profile 12 is arranged on the window frame 1, and a screen window structure 5 is arranged on the side of the conversion frame 11 close to the outdoor. The screen window structure 5 is connected to the outer frame outer profile 12. The screen window structure 5 includes a screen window frame 51 and a screen window profile 52. The screen window frame 51 is connected to the outer frame outer profile 12, the screen window profile 52 is hinged to the screen window frame 51, and the side of the screen window profile 52 close to the outdoor is flush with the outer frame outer profile 12. Through this design, the screen window structure 5 can be directly connected to the outer frame outer profile 12 without an additional additional frame, thereby simplifying the assembly process and improving the overall consistency and aesthetics of the outward-opening window.

[0048] Furthermore, a screen window sealing strip 53 is arranged between the screen window profile 52 and the screen window frame 51, and the screen window sealing strip 53 is used to seal the gap between the screen window profile 52 and the screen window frame 51.

[0049] Among them, the screen window rubber strip 53 is arranged between the screen window profile 52 and the screen window frame 51, which can effectively fill and seal the gap between the two, preventing mosquitoes from entering the room through the gap. At the same time, the use of the screen window rubber strip 53 also helps to improve the overall sealing performance, further enhancing the windproof and waterproof effects of the window. In this way, the technical solution of this application can improve the sealing performance and mosquito prevention effect of the outward-opening window without increasing the design width of the window frame 1 and the window sash 2, solving the problem of insufficient sealing performance in the prior art.

[0050] In the specific implementation process, the screen window rubber strip 53 can be made of flexible materials such as silicone or rubber to ensure its good elasticity and sealing performance. The shape and size of the screen window rubber strip 53 can be customized according to the size of the gap between the screen window profile 52 and the screen window frame 51 to ensure that it can fit tightly and effectively seal. The screen window rubber strip 53 can be fixed on the screen window profile 52 or the screen window frame 51 by pasting or embedding to ensure that it will not fall off or shift during use.

[0051] Furthermore, a double-notch structure 55 is provided in the screen window profile 52, and the double-notch structure 55 is used to fix different types of screen meshes 54.

[0052] Among them, the double-notch structure 55 provides two independent notches, which can be respectively used to fix different types of screen meshes 54. This design enables users to select and replace the types of screen meshes 54 according to their needs, increasing the flexibility of window use and the mosquito prevention effect. Through this structure, the limitation of the traditional single-notch structure in fixing the type of screen mesh 54 is solved, improving the functionality of the window and the user experience.

[0053] In the specific implementation process, the double-notch structure 55 of the screen window profile 52 can be realized by precision die processing. The size and shape of each notch can be designed according to the fixing requirements of different types of screen meshes 54. For example, one notch can be designed to be suitable for fixing traditional nylon screen meshes, while the other notch can be designed to be suitable for fixing stronger diamond screen meshes. Through this double-notch structure 55, users can flexibly select the appropriate type of screen mesh 54 in different seasons or different environments, thereby improving the mosquito prevention effect and the flexibility of window use.

[0054] In addition, the design of the double-notch structure 55 also takes into account the convenience of installing and replacing the screen mesh 54. Each notch can fix the screen mesh 54 through a simple buckle or sliding device, enabling users to replace the screen mesh 54 without using complex tools or performing cumbersome operations. This not only improves the user experience but also reduces the time and cost of maintaining and replacing the screen mesh 54.

[0055] Furthermore, a glass 6 is fixed between the first sash profile 21 and the second sash profile 22. A drain hole communicating with the outside is formed in the first sash profile 21 below the glass 6, and the drain hole and the second cavity 32 form a drainage channel 115 for draining water.

[0056] Among them, in the technical solution of this application, by fixing the glass 6 between the first sash profile 21 and the second sash profile 22, glass inner rubber strips 61 and glass outer rubber strips 62 are respectively arranged on both sides of the glass 6 to connect with the first sash profile 21 and the second sash profile 22, ensuring the basic structure and sealing performance of the window. A drain hole is formed in the first sash profile 21 below the glass 6, so that the accumulated water inside the sash 2 can be discharged through the drain hole. The drain hole and the second cavity 32 form a drainage channel 115. When the sash 2 is opened outward to the outside, the second cavity 32 is opened accordingly, and the water inside it flows along the sash 2 through the drain hole and is discharged to the outside, further ensuring that the accumulated water can be smoothly discharged out of the window and preventing water from seeping into the room. Through this design, the deficiency of the broken bridge aluminum alloy outward-opening window in terms of drainage is effectively solved, and the waterproof performance and service life of the window are improved.

[0057] Furthermore, an internal slot 221 for installing hardware fittings is provided between the second sash profile 22 below the glass 6 and the second frame body 112. The internal slot 221 and the drainage channel 115 are arranged at intervals, so that the hardware fittings are isolated from the water in the drainage channel 115.

[0058] Among them, in the three-seal structure of the broken bridge aluminum alloy outward-opening window, by providing an internal slot 221 between the second sash profile 22 below the glass 6 and the second frame body 112 for installing hardware fittings, and separating the internal slot 221 from the drainage channel 115. This design ensures that the hardware fittings do not directly contact the water in the drainage channel 115 and do not contact the outside air, thus avoiding the corrosion and damage of the hardware fittings by water, and improving the sealing performance and durability of the window. In this way, the hardware fittings can be conveniently installed and effectively protected, and their service life can be extended.

[0059] Specifically, the design of the internal slot 221 enables the hardware fittings to be stably installed between the second sash profile 22 and the second frame body 112 without directly contacting the drainage channel 115. In this way, even if there is water flowing in the drainage channel 115, it will not affect the performance and life of the hardware fittings. In addition, the interval arrangement between the internal slot 221 and the drainage channel 115 can also prevent water from penetrating into the window interior through the installation position of the hardware fittings, thereby further improving the overall sealing performance of the window.

[0060] The above are only embodiments of the present application and are not intended to limit the protection scope of the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
