Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a multi-waterproof structure for a conversion frame and an outward-opening window. Background Technology

[0002] Outward-opening windows are a type of casement window. Their sashes are connected to the window frame via hinges, and they rotate outwards when opened, saving interior space. This makes them particularly suitable for small apartments or scenarios requiring maximum utilization of interior space. The transition frame is a structural element in outward-opening window systems that connects the sash to the frame. For ease of production and installation, a cavity and gap must be left between the transition frame and the window frame. However, this allows dynamic water pressure to seep into the cavity gaps under wind and rain conditions. If not effectively blocked, rainwater can enter the room through the installation gaps of the transition frame under wind pressure, causing window leaks. Therefore, to improve the watertightness of outward-opening windows, a proper sealing process for the transition frame is necessary. Currently, the commonly used sealing structures and processes for outward-opening window transition frames and window frames have the following problems:

[0003] 1. Limitations of a single sealing strip: Traditional outward-opening windows rely on a single sealing strip, which is prone to aging or requires excessive adhesive, leading to installation difficulties. For example... Figure 1 As shown, the previous solution had a single transition frame sealing strip on the contact surface between the transition frame 100 and the frame 200. The single rubber strip was prone to aging and deformation, which could lead to sealing failure, and rainwater could easily seep in from the joint between the rubber strip and the profile.

[0004] 2. Micro-leakage problem at the fixing point of screw 11: The method of fastening with reverse washer 12 and C-groove ST4.2*22 round head steel self-tapping screws has the problem of micro-leakage at the fixing point of screw 11. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-waterproof structure for a conversion frame and an outward-opening window, which sets multiple abutting protrusions to form a wave-shaped structure, effectively increasing the contact area and helping to enhance the sealing performance.

[0006] Firstly, this utility model provides a multi-layer waterproof structure for a conversion frame, comprising:

[0007] Transition box;

[0008] The frame has a first engaging structure on the side facing the conversion frame;

[0009] The first sealing strip and the second sealing strip are both disposed between the frame and the conversion frame. The first sealing strip and the second sealing strip have at least two spaced abutting protrusions on the side facing the conversion frame. The abutting protrusions are used to abut against the conversion frame. The first sealing strip has a second locking structure on the side facing the frame. The second locking structure can lock onto the first locking structure. The second sealing strip is disposed on the side of the first sealing strip facing the outside.

[0010] This utility model provides a multi-layered waterproof structure for the transition frame. By setting a first and a second sealing strip between the frame and the transition frame, and designing at least two spaced abutment protrusions on the side of the sealing strip facing the transition frame, a wave-shaped structure is formed, effectively increasing the contact area and enhancing water-blocking performance. Furthermore, a pressure-compensating seal can be formed between the first and second sealing strips, adapting to the dynamic deformation of the window sash during use. When the window sash is opened or closed, the sealing strip automatically adjusts the contact pressure with the window frame based on its elastic deformation, ensuring a good sealing effect under different conditions and effectively preventing seal failure due to window sash deformation. Simultaneously, the first sealing strip is fixed to the frame by snap-fit, replacing the screw holes used in traditional installation methods, avoiding the risk of leakage caused by screw holes, and significantly improving the structure's waterproof performance.

[0011] Furthermore, the abutting protrusion includes a first inclined surface, an abutting plane, and a second inclined surface. The abutting plane is used to abut against the conversion frame. The first inclined surface and the second inclined surface are located on opposite sides of the abutting plane, and the distance between the first inclined surface and the second inclined surface increases from closer to the conversion frame to farther away from the conversion frame.

[0012] By adopting the above technical solution, the distance between the first inclined surface and the second inclined surface gradually increases from the closer to the conversion frame to the farther away from the conversion frame, so that the abutting protrusion can better distribute the pressure when subjected to force, improve the stability and durability of the structure, and reduce deformation or damage caused by excessive local force.

[0013] Furthermore, the abutting protrusion also includes a first arc surface and a second arc surface, with the opposite ends of the first arc surface connected to the first inclined surface and the abutting plane, and the opposite ends of the second arc surface connected to the second inclined surface and the abutting plane, respectively.

[0014] By employing the above technical solution, the design of the first and second arc surfaces of the abutment protrusion makes the contact between the sealing strip and the transition frame smoother, reducing stress concentration points. This smooth transition helps to further enhance sealing performance and prevent rainwater penetration.

[0015] Furthermore, the second sealing strip has an adhesive backing on the side facing the frame, which is used to adhere the second sealing strip to the frame.

[0016] Furthermore, a sealant layer is provided between the conversion frame and the frame, the sealant layer being used to seal the gap between the conversion frame and the frame.

[0017] By adopting the above technical solution, the sealant layer can effectively fill the tiny gaps between the conversion frame and the frame, forming an additional waterproof barrier, further enhancing the sealing performance, and effectively preventing rainwater from seeping into the room through the gaps between the conversion frame and the frame.

[0018] Furthermore, a first shielding wall extends from the frame, the first shielding wall being disposed on the side of the conversion frame facing the outside, and the sealant layer being disposed between the first shielding wall and the conversion frame; and / or, a second shielding wall extends from the conversion frame, the second shielding wall extending to the side of the frame facing the inside, and the sealant layer being disposed between the second shielding wall and the frame.

[0019] Using the above technical solution, the sealant layer is placed between the first shielding wall and the conversion frame and between the second shielding wall and the frame, which can effectively prevent rainwater from entering the connection area between the conversion frame and the frame and enhance the sealing performance.

[0020] Furthermore, the sealant layer is disposed between two adjacent abutting protrusions on the second sealant strip; and / or, the sealant layer is disposed between the first sealant strip and the second sealant strip.

[0021] By using the above technical solution, the sealant layer is placed between adjacent abutting protrusions on the second sealing strip and between the first and second sealing strips, which can effectively fill the tiny gaps in these areas, further enhance the sealing effect, and prevent rainwater penetration.

[0022] Furthermore, both the first sealing strip and the second sealing strip include a lower horizontal portion, a first side horizontal portion, and a second side horizontal portion. The lower horizontal portion is located between the lower horizontal portion of the frame and the lower horizontal portion of the conversion frame, and the first side horizontal portion and the second side horizontal portion are respectively located at opposite ends of the lower horizontal portion.

[0023] By employing the above technical solution, and placing the first and second sealing strips between the lower horizontal bar and the side horizontal bar near the lower horizontal bar, a screw-hole-free design is achieved at the lower horizontal bar connection between the transition frame and the window frame. This design effectively avoids the risk of water leakage caused by the presence of screw holes, significantly improving the waterproof performance of the outward-opening window. Meanwhile, other parts are still fixed with screw holes to ensure the overall structural stability. Since rainwater mainly seeps in from the lower horizontal bar, the installation of sealing strips on the lower horizontal bar effectively reduces rainwater infiltration, thereby improving the waterproof effect of the outward-opening window and extending its service life.

[0024] Furthermore, the first engaging structure is a C-shaped groove, and the second engaging structure includes a first engaging block and a second engaging block. The first engaging block and the second engaging block are respectively disposed on opposite sides of the first sealing strip, and the first engaging block and the second engaging block can engage and fix the first sealing strip in the C-shaped groove.

[0025] Secondly, the present invention provides an outward-opening window, including any of the above-mentioned conversion frame multi-waterproof structure.

[0026] As can be seen from the above, the multi-layer waterproof structure of the conversion frame provided by this utility model, by setting a first sealing strip and a second sealing strip between the frame and the conversion frame, and designing at least two spaced abutment protrusions on the side of the sealing strip facing the conversion frame to form a wave-shaped structure, effectively increases the contact area and enhances the water-blocking performance. In addition, the first sealing strip and the second sealing strip can also form a pressure-compensating seal, which can adapt to the dynamic deformation of the window sash during use. When the window sash is opened or closed, the sealing strip automatically adjusts the contact pressure with the window frame by relying on elastic deformation, ensuring that a good sealing effect is maintained under different conditions, effectively preventing sealing failure caused by window sash deformation. At the same time, the first sealing strip is fixed to the frame by snap-fit, replacing the screw holes in the traditional installation method, avoiding the risk of water leakage caused by screw holes, and significantly improving the waterproof performance of the structure.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0036] The multi-waterproof structure of the conversion frame disclosed in this utility model is mainly used in outward-opening windows to solve the problem of poor sealing performance and easy leakage at the connection between the conversion frame and the window frame in the prior art, thereby effectively improving the overall water tightness of the outward-opening window.

[0037] Reference Appendix Figure 2 Appendix Figure 3In one embodiment, the multiple waterproof structure of the transition frame includes a transition frame 100, a frame 200, a first sealing strip 300, and a second sealing strip 400. A first engaging structure 210 is provided on the side of the frame 200 facing the transition frame 100; both the first sealing strip 300 and the second sealing strip 400 are located between the frame 200 and the transition frame 100, and both the first sealing strip 300 and the second sealing strip 400 have at least two spaced abutment protrusions 310 on the side facing the transition frame 100, which are used to abut against the transition frame 100; a second engaging structure 320 is provided on the side of the first sealing strip 300 facing the frame 200, and the second engaging structure 320 can engage with the first engaging structure 210; the second sealing strip 400 is located on the side of the first sealing strip 300 facing outdoors.

[0038] Specifically, both the first sealing strip 300 and the second sealing strip 400 are made of waterproof foam sponge material, which has good hydrophobic effect and high material stability.

[0039] As can be seen from the above, the multi-layer waterproof structure of the conversion frame 100 provided by this utility model, by setting a first sealing strip 300 and a second sealing strip 400 between the frame 200 and the conversion frame 100, and designing at least two spaced abutment protrusions 310 on the side of the sealing strip facing the conversion frame 100, forms a wave-shaped structure, which effectively increases the contact area and enhances the water-blocking performance. In addition, the first sealing strip 300 and the second sealing strip 400 can also form a pressure-compensating seal, which can adapt to the dynamic deformation of the window sash during use. When the window sash is opened or closed, the sealing strip automatically adjusts the contact pressure with the window frame by relying on elastic deformation, ensuring that a good sealing effect is maintained under different conditions, effectively preventing sealing failure caused by window sash deformation. At the same time, the first sealing strip 300 is fixed to the frame 200 by snap-fit, replacing the screw holes in the traditional installation method, avoiding the risk of water leakage caused by screw holes, and significantly improving the waterproof performance of the structure.

[0040] Reference Appendix Figure 2 In one embodiment, the second sealing strip 400 has an adhesive backing 410 on the side facing the frame 200, and the adhesive backing 410 is used to stick the second sealing strip 400 to the frame 200.

[0041] Specifically, a protective film is provided on the side of the adhesive backing 410 away from the second sealing strip 400 before installation. The adhesive backing 410 can be a hot-melt pressure-sensitive adhesive; the protective film can be a PET protective film. During installation, first peel off the PET protective film on the hot-melt pressure-sensitive adhesive on the back of the second sealing strip 400, position it along the first engagement structure 210 and stick it to the frame 200, and then snap the first sealing strip 300 onto the first engagement structure 210 to complete the installation of the sealing strip.

[0042] In one embodiment, a sealant layer 500 is provided between the transition frame 100 and the frame 200, the sealant layer 500 being used to seal the gap between the transition frame 100 and the frame 200.

[0043] Specifically, the sealant layer 500 is a weather-resistant silicone sealant. After the first sealant strip 300 and the second sealant strip 400 are installed, the weather-resistant silicone sealant is applied, ensuring that the length of the sealant is the same as the length of the first sealant strip 300 and the second sealant strip 400, so as to achieve a seal between the conversion frame 100 and the frame 200 and improve the water tightness and air tightness of the product.

[0044] By adopting the above technical solution, the sealing layer 500 can effectively fill the tiny gap between the conversion frame 100 and the frame 200, forming an additional waterproof barrier, further enhancing the sealing performance, and effectively preventing rainwater from seeping into the room from the gap between the conversion frame 100 and the frame 200.

[0045] In one embodiment, a first shielding wall 220 extends from the frame 200 and is located on the side of the conversion frame 100 facing the outside, and a sealant layer 500 is located between the first shielding wall 220 and the conversion frame 100; and / or, a second shielding wall 110 extends from the conversion frame 100 and extends to the side of the frame 200 facing the inside, and a sealant layer 500 is located between the second shielding wall 110 and the frame 200.

[0046] Using the above technical solution, the sealing layer 500 is disposed between the first shielding wall 220 and the conversion frame 100 and between the second shielding wall 110 and the frame 200, which can effectively prevent rainwater from entering the connection area between the conversion frame 100 and the frame 200 and enhance the sealing performance.

[0047] In one embodiment, the sealant layer 500 is disposed between two adjacent abutting protrusions 310 on the second sealant strip 400; and / or, the sealant layer 500 is disposed between the first sealant strip 300 and the second sealant strip 400.

[0048] By adopting the above technical solution, the sealant layer 500 is placed between adjacent abutting protrusions 310 on the second sealant strip 400 and between the first sealant strip 300 and the second sealant strip 400, which can effectively fill the tiny gaps in these areas, further enhance the sealing effect, and prevent rainwater penetration.

[0049] Reference Appendix Figure 3 Appendix Figure 4In one embodiment, the first engaging structure 210 is a C-shaped groove 211, and the second engaging structure 320 includes a first engaging block 321 and a second engaging block 322. The first engaging block 321 and the second engaging block 322 are respectively disposed on opposite sides of the first sealing strip 300. The first engaging block 321 and the second engaging block 322 can engage and fix the first sealing strip 300 in the C-shaped groove 211.

[0050] Reference Appendix Figure 4 In one embodiment, the abutting protrusion 310 includes a first inclined surface 311, an abutting plane 312, and a second inclined surface 313. The abutting plane 312 is used to abut against the conversion frame 100. The first inclined surface 311 and the second inclined surface 313 are located on opposite sides of the abutting plane 312, and the distance between the first inclined surface 311 and the second inclined surface 313 increases from closer to the conversion frame 100 to farther away from the conversion frame 100.

[0051] By adopting the above technical solution, the distance between the first inclined surface 311 and the second inclined surface 313 is set to gradually increase from close to the conversion frame 100 to far away from the conversion frame 100, so that the abutting protrusion 310 can better disperse the pressure when subjected to force, improve the stability and durability of the structure, and reduce deformation or damage caused by excessive local force.

[0052] In one embodiment, the abutting protrusion 310 further includes a first arc surface 314 and a second arc surface 315. The opposite ends of the first arc surface 314 are respectively connected to the first inclined surface 311 and the abutting plane 312, and the opposite ends of the second arc surface 315 are respectively connected to the second inclined surface 313 and the abutting plane 312.

[0053] By adopting the above technical solution, the design of the first arc surface 314 and the second arc surface 315 of the abutment protrusion 310 makes the contact between the sealing strip and the conversion frame 100 smoother, reducing stress concentration points. This smooth transition helps to further enhance the sealing performance and prevent rainwater penetration.

[0054] Reference Appendix Figure 5 In one embodiment, both the first sealing strip 300 and the second sealing strip 400 include a lower horizontal portion 330, a first side horizontal portion 340 and a second side horizontal portion 350. The lower horizontal portion 330 is disposed between the lower horizontal portion of the frame 200 and the lower horizontal portion of the conversion frame 100, and the first side horizontal portion 340 and the second side horizontal portion 350 are respectively disposed at opposite ends of the lower horizontal portion 330.

[0055] By employing the above technical solution, and by placing the first sealing strip 300 and the second sealing strip 400 between the lower horizontal bar and the side horizontal bar near the lower horizontal bar, a screw-hole-free design is achieved at the lower horizontal bar connection between the conversion frame 100 and the window frame. This design effectively avoids the risk of water leakage caused by the presence of screw holes, significantly improving the waterproof performance of the outward-opening window. Meanwhile, other parts are still fixed with screw holes to ensure the overall structural stability. Since rainwater mainly seeps in from the lower horizontal bar, the installation of sealing strips on the lower horizontal bar effectively reduces rainwater infiltration, thereby improving the waterproof performance of the outward-opening window and extending its service life.
