Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, and in particular relates to an aluminum alloy inward opening window with a flush frame and sash. Background Technology

[0002] In the existing field of building doors and windows, aluminum alloy inward-opening windows are widely used due to their advantages such as high strength and strong corrosion resistance. However, traditional aluminum alloy inward-opening windows generally suffer from the technical defect of uneven frames and sashes: when the window sash is closed, there is often a significant height difference between the frame and the sash. This structural problem leads to two main defects: firstly, in terms of aesthetics, the uneven frame and sash structure disrupts the overall harmony of the building facade; secondly, in terms of functionality, the stepped height difference between the frame and the sash prevents the sealing strip from being fully pressed together, resulting in reduced air tightness and water tightness, which can easily lead to leakage, especially under extreme weather conditions.

[0003] Existing solutions often involve increasing the thickness of the sealing strip or adjusting the position of the hardware, but these improvements can only partially enhance the sealing performance and cannot fundamentally solve the core problem of uneven frame and sash structures. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum alloy inward-opening window with a flush frame and sash to solve the above-mentioned problems.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] Reference Figures 1-3 This utility model provides an aluminum alloy inward opening window with a flush frame and sash, comprising:

[0026] The frame sash 8 has a pressure line 1 on the side of the frame sash 8 closest to the interior. The pressure line 1 is located close to the glass 7. A decorative aluminum 2 is installed on the inner side of the pressure line 1. The decorative aluminum 2 is used to make the frame sash 8 flush with the window frame. A sealing strip assembly is installed on the side of the decorative aluminum 2 closest to the glass 7.

[0027] The heat insulation strip assembly includes a heat insulation strip 9 and a heat insulation strip 10 disposed within the frame 8. The heat insulation strip 9 has a first heat insulation cavity structure, and a protrusion is provided on the side of the heat insulation strip 9 near the heat insulation strip 10. The heat insulation strip 9, the heat insulation strip 10 and the frame 8 are connected by the protrusion to form a second heat insulation cavity structure.

[0028] The main function of the decorative aluminum 2 is to achieve a flush fit between the frame and sash by installing it on the frame sash 8 and keeping it flush with the frame sash 8, thus improving the sealing between the frame sash and the window frame. At the same time, installing the decorative aluminum 2 on the frame sash 8 further enhances the aesthetics of the frame sash. The main function of the sealing strip assembly is to ensure the sealing performance of the frame sash 8. The main function of the first thermal insulation cavity structure is to improve the thermal insulation performance of the frame sash 8. The main function of the protruding part is to divide the space between the thermal insulation strip 9 and the thermal insulation rubber strip 10 into multiple small cavities, reducing convection, thereby allowing the second thermal insulation cavity structure to further improve the thermal insulation performance of the frame sash. Overall, the inward-opening window of this utility model achieves a flush fit between the frame sash and the window frame by setting decorative aluminum at the pressure line, improving aesthetics. Simultaneously, by setting the first and second thermal insulation cavity structures in the frame sash, the thermal insulation performance of the frame sash is effectively improved.

[0029] The design is further optimized so that the sealing strip assembly includes an elongated aluminum 4, which is fixedly connected to the side wall of the pressure line 1 near the interior. A sealing strip 3 is fixedly connected to the elongated aluminum 4, and the sealing strip 3 is detachably connected to the decorative aluminum 2.

[0030] To further optimize the design, a snap-fit ​​groove 6 is provided on the side of the decorative aluminum 2 near the pressure line 1, and the sealing strip 3 is snapped into the snap-fit ​​groove 6.

[0031] In a further optimized design, a slot 31 is provided on one side of the sealing strip 3, and the elongated aluminum 4 is conformally arranged to the slot 31 and inserted into the slot 31. Two sets of contact strips 32 are fixedly connected to the side of the sealing strip 3 near the slot 31. The two contact strips 32 are arranged on both sides of the slot 31 and abut against the pressure line 1. The two opposite sides of the sealing strip 3 near the contact strips 32 are respectively provided with a locking platform 33, which is adapted to the locking groove 6.

[0032] like Figure 1 and Figure 3 As shown, the sealing strip 3 is U-shaped. When the decorative aluminum 2 is installed onto the pressure line 1, the contact strip 32 above it contacts and deforms with the pressure line 1. At the same time, the sealing strip 3, through deformation, fits more tightly with the elongated aluminum 4, thus achieving a sealed connection with the pressure line 1. A retaining platform 33 is formed between the edge of the contact strip 32 and the edge of the sealing strip 3. The sealing strip 3 is fixed in the retaining groove 6 by the abutment of the retaining platform 33 against the edge of the opening.

[0033] The design is further optimized by fixing a limiting seat 5 to the bottom of the snap-fit ​​slot 6, with the limiting seat 5 abutting against the sealing strip 3.

[0034] In this embodiment, the sealing strips 3 are set to 50mm segments, evenly installed on the elongated aluminum 4 at 200mm intervals. The elongated aluminum 4 is 30mm long, and 4-5 strips are installed on each side. The slots 31 are set to conform to the shape of the elongated aluminum 4, which makes the installation of the sealing strips 3 simple and prevents them from falling off. After installing the sealing strips 3, the decorative aluminum 2 can be directly fastened to the pressure line 1 to form a flush frame and sash.

[0035] Further optimization of the scheme: the first heat insulation cavity structure includes several cavities 91, which are respectively fixedly connected to the side of the heat insulation strip 9 away from the heat insulation adhesive strip 10.

[0036] like Figure 1 and Figure 2 As shown, several cavities 91 can improve thermal insulation performance, eliminating the need for foam filling. The cavities at the frame-sash overlap are divided to reduce energy loss in this area through convection.

[0037] Further optimization of the design: the protrusion includes several parallel ribs 93. One end of each rib 93 is fixedly connected to the side wall of the heat insulation strip 9 near the heat insulation strip 10. The other end of each rib 93 is located near the heat insulation strip 10 and has a gap between it and the heat insulation strip 10.

[0038] like Figure 1 As shown in Figure 2, when used in conjunction with the thermal insulation strip 10, several ribs 93 can cut the large cavity into multiple small cavities, reducing convection and lowering the profile's U-value. The ribbed design improves the thermal insulation performance of the insulation zone without adding any extra processes during profile composite, eliminating the need for additional processes such as foam material pasting, insertion, or injection.

[0039] In a further optimized design, heat-fusion wires 92 are fixedly connected to the two ends of the heat insulation strip 9 near the indoor and outdoor sides, respectively. The side of the heat-fusion wire 92 away from the heat insulation strip 9 has a groove, and the side of the heat-fusion wire 92 with the groove is in contact with the frame sash 8.

[0040] like Figure 1 and Figure 2 As shown, the hot melt line 92 has a U-shaped structure, which can improve the water tightness and air tightness of the frame sash.

[0041] The design is further optimized by fixing the inner side of the decorative aluminum 2 to the side of the frame sash 8 that is closer to the interior with the connector 11.

[0042] Example 2:

[0043] like Figure 1 and Figure 4As shown, two sets of multi-cavity heat insulation strips 12 are also provided inside the frame sash 8, and several ribs 93 are fixedly connected to the opposite side walls of the two multi-cavity heat insulation strips 12.

[0044] The multi-cavity structure of the multi-cavity thermal insulation strip 12 can improve thermal insulation performance, especially when used in situations with narrow visible surfaces, eliminating the need for foam filling and improving product cost-effectiveness. When used in conjunction with several ribs 93, it can also divide a large cavity into multiple smaller cavities, reducing convection and lowering the profile's U-value.
