Description

Technical Field

[0001] The present invention relates to the technical field of door and window installation, and particularly to a high-strength window frame connector for aluminum alloy doors and windows and an installation method thereof. Background Art

[0002] In the technical field of door and window installation, aluminum alloy doors and windows have been widely used due to their advantages such as light weight, high strength, beautiful appearance and durability. As a key component in the installation of aluminum alloy doors and windows, the performance of the window frame connector directly affects the overall quality and use experience of the doors and windows.

[0003] Traditional aluminum alloy door and window frame connectors have many problems in terms of sealing. Most connectors are sealed with sealant glue. However, the glue construction not only has cumbersome procedures and high technical requirements for construction workers, but also in the long-term use process, the glue is easily affected by environmental factors such as ultraviolet radiation, temperature change, rain erosion, etc., resulting in a decline in sealing performance, and phenomena such as aging, cracking, and degumming occur. Once the sealant glue fails, air, rainwater, etc. will penetrate into the room along the gap between the window frame and the connector, causing indoor humidity, mildew, affecting the comfort of the indoor environment, and may also cause damage to the walls, furniture, etc. around the doors and windows, increasing the later maintenance cost.

[0004] In summary, with the continuous improvement of the requirements for energy conservation, environmental protection and living quality in the construction industry, the market urgently needs a high-strength window frame connector for aluminum alloy doors and windows with good sealing performance, high structural strength and convenient installation to solve the above problems existing in traditional connectors and meet the high-quality and high-performance requirements of modern buildings for doors and windows.

Detailed implementation mode

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Embodiment 1. The present invention designs a high-strength window frame connecting piece for aluminum alloy doors and windows, such as Figure 1 , Figure 2 , Figure 5 , which mainly includes components such as a connecting piece body 1, a window frame body 2, a main sealing ring 3, a rigid shaping ring 4, an elastic PVC snap ring 5, a peripheral sealing ring part 6, and an inner peripheral sealing ring part 7. The specific structural design is as follows:

[0036] I. Overall structure: As shown in Figure 1 , Figure 2 , this high-strength window frame connecting piece for aluminum alloy doors and windows is mainly composed of a connecting piece body 1 and a window frame body 2. The window frame body 2 is fixedly installed inside the inner periphery of the connecting piece body 1 through a bolt member and a screw member. This connection method ensures a firm connection between the window frame and the connecting piece, laying a foundation for subsequent sealing and overall performance.

[0037] As shown in Figure 5 , Figure 6 , a first card slot 101 is provided inside the inner periphery of the connecting piece body 1, and a second card slot 201 that is aligned and matched with the first card slot 101 is provided on the outer periphery of the window frame body 2. The precise cooperation of the two card slots provides space for subsequent installation of sealing components, ensuring the stability and accuracy of the sealing structure.

[0038] II. Main sealing ring 3: As shown in Figure 3 , Figure 4 , Figure 6 , Figure 7, a main sealing ring 3 is embedded and installed at the positions of the first clamping groove 101 and the second clamping groove 201. Extrusion convex rings 301 are provided on both the inner and outer ring sides of the main sealing ring 3 in the vertical direction. The extrusion convex ring 301 on the outer ring side is in extrusion contact with the outer ring extrusion surface 104 of the inner wall of the first clamping groove 101, and the extrusion convex ring 301 on the inner ring side is in extrusion contact with the inner ring extrusion surface 204 of the inner wall of the second clamping groove 201. The arc-shaped structure design of the extrusion convex ring 301 enables it to have a larger contact area with the inner wall of the clamping groove, resulting in a better sealing effect. When the external seal ages, this structure can effectively prevent the penetration of air, rainwater, etc., forming a solid internal sealing line of defense.

[0039] III. Rigid shaping ring 4: As Figure 3 , Figure 4 , Figure 7 , Figure 8 , a ring-shaped shaping groove 302 is formed on the outer side of the main sealing ring 3 in the horizontal direction, and a rigid shaping ring 4 is clamped at the position of the shaping groove 302. The rigid shaping ring 4 is adapted to the specifications and dimensions of the shaping groove 302, and the cross-sectional shapes of both are isosceles trapezoids. This design enables the rigid shaping ring 4 to be tightly clamped in the shaping groove 302, playing a role in supporting and shaping the main sealing ring 3, preventing the main sealing ring 3 from deforming when subjected to external forces, and thus ensuring the stability of the sealing performance. At the same time, from the perspective of the key points of dimension design, the tight fit between the rigid shaping ring 4 and the shaping groove 302 is also considered based on the stability of the overall sealing structure, ensuring that during long-term use, the components will not become loose due to mismatched dimensions.

[0040] IV. Elastic PVC snap ring 5: As Figure 4 , Figure 5 , Figure 8 , Figure 9 , an elastic PVC snap ring 5 is also clamped at the positions of the first clamping groove 101 and the second clamping groove 201, which is located on the outer side of the main sealing ring 3 in the horizontal direction. A positioning protrusion 501 that snaps into a positioning notch 401 is provided on one side of the elastic PVC snap ring 5 facing the rigid shaping ring 4. The positioning notch 401 and the positioning protrusion 501 are adapted to each other in terms of specifications and dimensions, and the cross-sections of both are triangular. This matching method enables the positioning protrusion 501 to accurately snap into the positioning notch 401 of the rigid shaping ring 4 after the elastic PVC snap ring 5 is installed, further enhancing the stability of the entire sealing structure and preventing relative displacement between components.

[0041] Let the width dimension of the elastic PVC snap ring 5 after installing the outer peripheral sealing member 6 and the inner peripheral sealing member 7 be L a , let the sum of the internal groove depths of the first clamping groove 101 and the second clamping groove 201 after combination be H n , let the width dimension of the outer opening of the combination of the first clamping groove 101 and the second clamping groove 201 be H w , then H w <La <H n This size design enables the elastic PVC clamping ring 5 to be tightly installed in the clamping groove, ensuring both the convenience of installation and its stability in the clamping groove without wobbling or falling off. Combining Figure 10 , let the maximum elastic deformation difference of the elastic PVC clamping ring 5 be ΔL, and let the groove depth dimensions of the first clamping groove 101 and the second clamping groove 201 be the same and be D, then ΔL > D. This design ensures that the elastic PVC clamping ring 5 can be smoothly snapped into the clamping groove during installation, and after being snapped in, it can generate sufficient extrusion force using its own elasticity to make the contact between each sealing component closer, thereby improving the sealing performance.

[0042] V. Outer peripheral sealing ring member 6 and inner peripheral sealing ring member 7: As Figure 3 、 Figure 4 、 Figure 5 , the outer ring side of the elastic PVC clamping ring 5 in the vertical direction is equipped with an outer peripheral sealing ring member 6 that is in extrusion contact with the inner wall of the first clamping groove 101, and the inner ring side is equipped with an inner peripheral sealing ring member 7 that is in extrusion contact with the inner wall of the second clamping groove 201. The outer peripheral sealing ring member 6 and the inner peripheral sealing ring member 7 respectively seal the openings at the outer ends of the first clamping groove 101 and the second clamping groove 201, forming an external sealing protection, which is combined with the internal sealing line of the main sealing ring 3 to further enhance the sealing effect.

[0043] As Figure 4 、 Figure 6 、 Figure 9 , an outer ring sealing inclined surface 103 is provided at the opening position of the outer end of the first clamping groove 101, and a first raised band 601 that is in extrusion fit with the outer ring sealing inclined surface 103 is provided on the horizontally outward side of the outer peripheral sealing ring member 6. An inner ring sealing inclined surface 203 is provided at the opening position of the outer end of the second clamping groove 201, and a second raised band 701 that is in extrusion fit with the inner ring sealing inclined surface 203 is provided on the horizontally outward side of the inner peripheral sealing ring member 7. The first raised band 601 and the second raised band 701 are respectively in extrusion fit with the outer ring sealing inclined surface 103 and the inner ring sealing inclined surface 203, playing a role in strengthening the seal. At the same time, a first inner inclined surface 602 with the same slope as the outer ring sealing inclined surface 103 is provided on one side of the first raised band 601 facing the outer ring sealing inclined surface 103, and a first outer inclined surface 603 for blocking foreign objects from the outside is provided on the other side. A second inner inclined surface 702 with the same slope as the inner ring sealing inclined surface 203 is provided on one side of the second raised band 701 facing the inner ring sealing inclined surface 203, and a second outer inclined surface 703 for blocking foreign objects from the outside is provided on the other side. These inclined surface designs can guide rainwater and impurities to drain away smoothly, preventing them from entering the gap and affecting the sealing performance.

[0044] As Figure 4 、 Figure 6 、 Figure 9, the outer peripheral sealing ring member 6 is provided with a first extrusion portion 604 that wraps the vertical outer ring side edge of the elastic PVC snap ring 5, and the inner wall of the first card slot 101 is provided with an outer ring limiting inclined surface 102 that abuts against the first extrusion portion 604. The inner peripheral sealing ring member 7 is provided with a second extrusion portion 704 that wraps the vertical inner ring side edge of the elastic PVC snap ring 5, and the inner wall of the second card slot 201 is provided with an inner ring limiting inclined surface 202 that abuts against the second extrusion portion 704. These structures further enhance the connection stability between the sealing components, prevent the elastic PVC snap ring 5 from moving during use, and thus ensure the durability of the sealing effect.

[0045] Embodiment 2. The present invention designs an installation method for a high-strength window frame connector of an aluminum alloy door and window, including the installation of the main sealing ring 3, the hardening shaping ring 4, the elastic PVC snap ring 5, etc. The specific content of each link is as follows:

[0046] Link 1. Install the main sealing ring

[0047] First, after the connector body 1 is fixed, install the window frame body 2 inside the connector body 1 through the plug-in member and the screw member. During the installation process, carefully check whether the position of the window frame body 2 is accurate to ensure that it fits closely with the connector body 1 and there are no obvious gaps or misalignments at each connection part.

[0048] Then, squeeze and embed the main sealing ring 3 into the first card slot 101 and the second card slot 201. Since the extrusion protruding ring 301 of the main sealing ring 3 needs to closely cooperate with the inner wall of the card slot, there may be a certain resistance during installation. At this time, the construction personnel can use some auxiliary tools, such as a small rubber hammer, to gently tap the main sealing ring 3 to make it slowly and evenly embed into the card slot. During the embedding process, always pay attention to the position of the main sealing ring 3 to ensure that it completely falls into the card slot and the extrusion protruding ring 301 is in full contact with the outer ring extrusion surface 104 of the first card slot 101 and the inner ring extrusion surface 204 of the second card slot 201 to form a good sealing foundation. At the same time, place the shaping groove 302 of the main sealing ring 3 facing outward. This placement method provides convenience for the subsequent installation of the hardening shaping ring 4 and ensures the sequentiality and accuracy of the installation of each component.

[0049] Link 2. Install the hardening shaping ring

[0050] First, install the rigid shaping ring 4 in the shaping groove 302 on the outer side of the main sealing ring 3 in the horizontal direction. Since the specifications of the rigid shaping ring 4 and the shaping groove 302 are adapted to each other, during installation, the rigid shaping ring 4 needs to be aligned with the shaping groove 302, and then press it in with uniform force. To ensure the accuracy of installation, the construction personnel can first snap one side edge of the rigid shaping ring 4 into one end of the shaping groove 302, and then slowly push it along the contour of the shaping groove 302 until the rigid shaping ring 4 is completely embedded in the shaping groove 302. When installing the rigid shaping ring 4, position its positioning notch 401 facing outwards, which is for the subsequent precise cooperation with the positioning protrusion 501 of the elastic PVC snap ring 5 to ensure the installation accuracy and stability of the entire sealing structure.

[0051] After installation, carefully check whether the rigid shaping ring 4 is installed in place and whether there are any gaps or looseness between it and the shaping groove 302. You can gently nudge the rigid shaping ring 4 with your hand to feel its stability. If any problems are found, they need to be adjusted or reinstalled in a timely manner to ensure that the rigid shaping ring 4 can be firmly clamped in the shaping groove 302, providing reliable support for the stable operation of the subsequent sealing structure.

[0052] Step Three: Install the Elastic PVC Snap Ring

[0053] First, use a flexible crowbar tool to install the elastic PVC snap ring 5. The flexible crowbar tool is selected because of its soft texture, which can avoid damage to the elastic PVC snap ring 5 and the card slot during the operation. During installation, align the outer ring side edge of the elastic PVC snap ring 5 in the vertical direction with the first card slot 101 and the inner ring side edge with the second card slot 201. Then use the flexible crowbar tool to gradually snap the outer ring side edge of the elastic PVC snap ring 5 into the first card slot 101 and the inner ring side edge into the second card slot 201 starting from one side of the elastic PVC snap ring 5. During the prying process, pay attention to controlling the force to avoid excessive force causing deformation or damage to the elastic PVC snap ring 5. At the same time, when installing the elastic PVC snap ring 5, place the first raised band 601 and the second raised band 701 facing outwards, which is convenient for the subsequent extrusion cooperation between the first raised band 601 and the outer ring sealing inclined surface 103, and the second raised band 701 and the inner ring sealing inclined surface 203 to achieve a good sealing effect.

[0054] During the process of snapping the elastic PVC snap ring 5 into the card slot, the situation of position deviation or unsmooth snapping may occur. At this time, the construction personnel can use a crowbar to fine-tune the elastic PVC snap ring 5 to ensure that the outer peripheral sealing member 6 on the outer ring side of the elastic PVC snap ring 5 is in close extrusion contact with the inner wall of the first card slot 101, and the inner peripheral sealing member 7 on the inner ring side is in close extrusion contact with the inner wall of the second card slot 201. At the same time, pay attention to the relative position of the positioning protrusion 501 of the elastic PVC snap ring 5 and the positioning notch 401 of the rigid shaping ring 4 to ensure that the positioning protrusion 501 can be smoothly snapped into the positioning notch 401 after installation.

[0055] After all the above components are installed, the positioning protrusion 501 on the inner side of the elastic PVC snap ring 5 in the horizontal direction will automatically snap into the positioning notch 401 of the rigid shaping ring 4. This mating process not only further enhances the connection stability between the elastic PVC snap ring 5 and the rigid shaping ring 4, but also enables the rigid shaping ring 4 to effectively support the main sealing ring 3. The rigid shaping ring 4 supports the main sealing ring 3 to form a pressurized abutment on the periphery, making the contact between the extrusion protrusion ring 301 of the main sealing ring 3 and the inner wall of the card slot closer, and further improving the internal sealing effect.

[0056] At this time, the outer peripheral sealing member 6 seals the opening at the outer end edge of the first card slot 101, and the inner peripheral sealing member 7 seals the opening at the outer end edge of the second card slot 201, and the sealing installation work of the entire window frame connector is completed. Finally, a comprehensive inspection is carried out on the installed window frame connector. The inspection contents include whether the connections between the components are tight, whether there are gaps or looseness; whether the extrusion fit between the first protrusion band 601 and the outer ring sealing inclined surface 103, and the second protrusion band 701 and the inner ring sealing inclined surface 203 is good, and whether it can effectively prevent rainwater, impurities, etc. from entering; whether the sealing components are complete, whether there are damages or deformations, etc. If any problems are found, repair or adjustment shall be carried out in a timely manner to ensure that the window frame connector can achieve good sealing performance and stable structural strength, meeting the use requirements of aluminum alloy doors and windows.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
