Description

Technical Field

[0001] This application relates to the technical field of doors and windows, and particularly to a broken bridge aluminum passive window. Background Art

[0002] The Beijing Municipal Commission of Planning and Natural Resources and the Beijing Municipal Market Supervision and Administration Bureau approved and issued the latest "Energy Efficiency Design Standard for Residential Buildings" in 2020, which requires that the heat transfer coefficient K value of building exterior windows ≤ 1.1 W / ㎡∙K.

[0003] With the development trend of building energy conservation, people will have higher requirements for the energy-saving standards of exterior windows, and the traditional sealing material design method can no longer meet the requirements of passive ultra-low energy consumption buildings for exterior windows. Summary of the Invention

[0004] To help meet the requirements of passive ultra-low energy consumption buildings for exterior windows, this application provides a broken bridge aluminum passive window.

[0005] A broken bridge aluminum passive window provided by this application adopts the following technical solutions:

[0006] A broken bridge aluminum passive window includes a window frame and a movable window hinged within the window frame. The window frame includes an outdoor-side broken bridge aluminum alloy frame and an indoor-side broken bridge aluminum alloy frame. The movable window includes an outdoor-side broken bridge aluminum alloy inward-opening sash frame body and an indoor-side broken bridge aluminum alloy inward-opening sash frame body. Between the outdoor-side broken bridge aluminum alloy frame and the indoor-side broken bridge aluminum alloy frame, and between the outdoor-side broken bridge aluminum alloy inward-opening sash frame body and the indoor-side broken bridge aluminum alloy inward-opening sash frame body, they are all connected by heat insulation strips. Multiple layers of vacuum glass are installed inside the movable window, and the vacuum glass is located between the outdoor-side broken bridge aluminum alloy inward-opening sash frame body and the indoor-side broken bridge aluminum alloy inward-opening sash frame body. Glass rubber strips are provided between both the outdoor-side broken bridge aluminum alloy inward-opening sash frame body and the indoor-side broken bridge aluminum alloy inward-opening sash frame body and the vacuum glass. On the sides where the movable window and the window frame are close to each other, there are heat insulation connecting rubber strips for mutual overlapping.

[0007] By adopting the above technical solutions, both the window frame and the movable window use ultra-low energy consumption heat insulation broken bridge aluminum alloy profiles, and are matched with multiple layers of vacuum glass, which can improve the heat preservation and sealing performance. The glass rubber strips and the heat insulation connecting rubber strips further seal, thus helping to meet the requirements of passive ultra-low energy consumption buildings for exterior windows.

[0008] Preferably, a sealing rubber strip is provided between the outdoor-side broken bridge aluminum alloy inward-opening sash frame body and the indoor-side broken bridge aluminum alloy inward-opening sash frame body, and the sealing rubber strip is arranged along the edge of the vacuum glass.

[0009] By adopting the above technical solutions, the sealing strip further seals the connection of the vacuum glass, and to a certain extent improves the heat preservation and sealing performance of the movable window, which helps to meet the requirements of passive ultra-low energy consumption buildings for external windows.

[0010] Preferably, heat insulation cotton is provided between the outdoor-side broken bridge aluminum alloy frame and the indoor-side broken bridge aluminum alloy frame, and between the outdoor-side broken bridge aluminum alloy inward-opening sash frame and the indoor-side broken bridge aluminum alloy inward-opening sash frame. The heat insulation cotton between the outdoor-side broken bridge aluminum alloy inward-opening sash frame and the indoor-side broken bridge aluminum alloy inward-opening sash frame is located between the sealing strip and the corresponding heat insulation connection strip.

[0011] By adopting the above technical solutions, the setting of the heat insulation cotton further improves the heat preservation performance of the window frame and the movable window, which helps to meet the requirements of passive ultra-low energy consumption buildings for external windows.

[0012] Preferably, the heat insulation connection strip is a heat insulation nylon strip.

[0013] By adopting the above technical solutions, the heat insulation nylon strip has good heat insulation and sealing properties, which helps to ensure the sealing and heat preservation between the window frame and the movable window; at the same time, the heat insulation nylon strip is resistant to aging, has high strength, and has a long service life.

[0014] Preferably, a fixing plate is provided on the lower horizontal side of the outdoor-side broken bridge aluminum alloy inward-opening sash frame. The fixing plate is located between the vacuum glass and the outdoor-side broken bridge aluminum alloy frame. A sliding groove is provided on the bottom wall of the fixing plate. A rain receiving box is slidably arranged in the sliding groove. The sliding direction of the rain receiving box is parallel to the depth direction of the sliding groove. A water outlet hole is provided on one side of the rain receiving box away from the outdoor-side broken bridge aluminum alloy inward-opening sash frame. A rain inlet is provided on one side of the fixing plate close to the water outlet hole. The rain inlet is communicated with the sliding groove. The rain inlet is located above the rain receiving box. The cross-sectional area of the rain inlet is larger than that of the water outlet hole. A pulling member for pulling the rain receiving box to slide towards the direction close to the sliding groove is arranged in the sliding groove.

[0015] By adopting the above technical solutions, when it rains, rainwater flows into the rain receiving box from the movable window and the fixing plate through the rain inlet. Since the cross-sectional area of the water outlet hole is small, as the rainwater increases, the gravity increases, driving the rain receiving box to move out of the sliding groove towards the direction away from the sliding groove, so that the rain receiving box shields the overlapping part between the movable window and the window frame, making it difficult for rainwater to penetrate into the room.

[0016] Preferably, the pulling member includes an elastic rope for pulling the rain receiving box to slide towards the direction close to the sliding groove. One end of the elastic rope is arranged on the inner wall of the sliding groove, and the other end is arranged on the rain receiving box.

[0017] By adopting the above technical solution, after the rainwater in the rain collecting box completely flows out from the water outlet, the elastic rope pulls the rain collecting box to move into the chute in the direction close to the chute, so that it is not easy to affect the opening and closing of the movable window; at the same time, the rain collecting box is located inside the fixing plate, which facilitates the stacking and transportation of the movable window and is not easy to cause unnecessary damage.

[0018] Preferably, a waterproof cloth is arranged along the circumferential direction of the top wall of the rain collecting box. The side of the waterproof cloth away from the rain collecting box is arranged on the inner wall of the chute, and the waterproof cloth is located below the rain inlet.

[0019] By adopting the above technical solution, the rainwater entering from the water inlet flows into the rain collecting box along the waterproof cloth, so as to reduce the possibility of the rainwater flowing out from the gap between the rain collecting box and the inner wall of the chute, and further enable the rainwater not to easily penetrate into the room.

[0020] Preferably, the distance from the side of the rain collecting box away from the water outlet hole to the side of the fixing plate close to the rain inlet gradually decreases in the direction away from the rain inlet.

[0021] By adopting the above technical solution, the side of the rain collecting box away from the water outlet hole is inclined, which can guide the rainwater, and further prevent the rainwater from easily penetrating into the lap joint between the movable window and the window frame.

[0022] Preferably, a rotating shaft penetrates through the side of the fixing plate close to the vacuum glass. The rotating shaft is rotatably arranged on the inner opening frame body of the outdoor side broken bridge aluminum alloy. The rotation axis of the rotating shaft is arranged in the horizontal direction, and the rotation axis of the rotating shaft is parallel to the plane where the vacuum glass is located. The rotating shaft drives the fixing plate to rotate in the direction close to or away from the vacuum glass. A water-proof connecting cloth is arranged between the side of the fixing plate close to the inner opening frame body of the outdoor side broken bridge aluminum alloy and the inner opening frame body of the outdoor side broken bridge aluminum alloy. The water-proof connecting cloth is used to pull the fixing plate to abut against the inner opening frame body of the outdoor side broken bridge aluminum alloy. A torsion spring is movably sleeved on the rotating shaft. One end of the torsion spring is arranged on the fixing plate, and the other end is arranged on the inner opening frame body of the outdoor side broken bridge aluminum alloy. The torsion spring is used to drive the fixing plate to rotate in the direction close to the vacuum glass. A storage cavity is arranged on the side of the fixing plate close to the rain inlet. The storage cavity is located on the side of the rain inlet close to the rotating shaft. A fire-proof board is slidably arranged in the storage cavity. The fire-proof board is used to abut against the glass sealant strip on the side close to the inner opening frame body of the outdoor side broken bridge aluminum alloy. A sealing film for sealing the storage cavity is arranged on the fixing plate. The melting point of the sealing film is lower than the melting point of the glass sealant strip. The melting point of the water-proof connecting cloth is lower than the melting point of the sealing film. A pushing member for pushing the fire-proof board to slide in the direction away from the storage cavity is arranged in the storage cavity.

[0023] By adopting the above technical solution, when a fire breaks out on adjacent floors and the fire spreads upwards from outside the window, as the temperature rises, the water-blocking connecting cloth first melts, thereby reducing the tension on the fixing plate. Under the action of the torsion spring, the fixing plate rotates towards the direction close to the vacuum glass, so that the fixing plate abuts against the vacuum glass to support the vacuum glass. Then the sealing film melts, and the fireproof board is pushed by the pushing member towards the glass sealant strip close to it, covering the glass sealant strip close to it, which can protect the glass sealant strip, making it not easy to melt, and the vacuum glass is not easy to loosen, improving fire resistance and safety.

[0024] Preferably, the pushing member includes a spring for pushing the fireproof board to slide away from the storage cavity. One end of the spring is arranged on the bottom wall of the storage cavity, and the other end is arranged on the fireproof board.

[0025] By adopting the above technical solution, after the sealing film melts, the compressed spring pushes the fireproof board towards the glass sealant strip close to it, and the fireproof board covers the glass sealant strip close to it, which can protect the glass sealant strip, making it not easy to melt, and the vacuum glass is not easy to loosen, improving fire resistance and safety.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] Both the window frame and the movable window adopt ultra-low energy consumption heat-insulating broken bridge aluminum alloy profiles, which are matched with multiple layers of vacuum glass, and can improve the heat preservation and sealing performance. The glass sealant strip and the heat-insulating connection sealant strip are further sealed, thereby helping to meet the requirements of passive ultra-low energy consumption buildings for external windows.

Detailed implementation mode

[0034] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings.

[0035] An embodiment of this application discloses a broken bridge aluminum passive window. Referring to Figure 1 , the broken bridge aluminum passive window includes a window frame 1, a mullion 22, and a movable window 2 hinged in the window frame 1 through a hinge. The mullion 22 is fixedly installed in the window frame 1. The mullion 22 is located on one side of the movable window 2. A fixed window 23 is installed in the window frame 1. The fixed window 23 is located on the side of the mullion 22 away from the movable window 2.

[0036] Referring to Figure 1 and Figure 2 , the window frame 1 includes an outdoor side broken bridge aluminum alloy frame 101 and an indoor side broken bridge aluminum alloy frame 102. The cross-sections of the outdoor side broken bridge aluminum alloy frame 101 and the indoor side broken bridge aluminum alloy frame 102 are both rectangular frames. The window frame 1 is a 95-series broken bridge aluminum window. The movable window 2 includes an outdoor side broken bridge aluminum alloy inward-opening sash frame 201 and an indoor side broken bridge aluminum alloy inward-opening sash frame 202. The outdoor side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor side broken bridge aluminum alloy inward-opening sash frame 202 are hinged to the window frame 1 through the same hinge. The cross-sections of the outdoor side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor side broken bridge aluminum alloy inward-opening sash frame 202 are both rectangular frames. The outdoor side broken bridge aluminum alloy frame 101 and the indoor side broken bridge aluminum alloy frame 102, as well as the outdoor side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor side broken bridge aluminum alloy inward-opening sash frame 202, are connected by heat insulation strips 27. The heat insulation strips 27 are polyamide heat insulation strips 27. Cavities are provided inside the profiles of the window frame 1 and the movable window 2, which helps to improve the heat insulation effect.

[0037] Referring to Figure 1 and Figure 2, inside the movable window 2, multiple layers of vacuum glass 3 are installed. In this embodiment, it has a structure of three glasses with two insulating spaces. The vacuum glass 3 has good heat insulation performance. The vacuum glass 3 is located between the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor-side broken bridge aluminum alloy inward-opening sash frame 202. Glass glue strips 4 are bonded between both the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor-side broken bridge aluminum alloy inward-opening sash frame 202 and the vacuum glass 3. The glass glue strips 4 are ethylene propylene diene monomer (EPDM) composite foamed glue strips. On one side where the movable window 2 and the window frame 1 are close to each other, heat insulation connection glue strips 5 for mutual lapping are fixedly connected. The heat insulation connection glue strips 5 are heat insulation nylon strips, and the heat insulation nylon strips have good heat insulation and sealing properties, thus helping to ensure the sealing and heat insulation between the window frame 1 and the movable window 2.

[0038] Refer to Figure 2 , a sealing glue strip 6 is fixedly arranged between the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor-side broken bridge aluminum alloy inward-opening sash frame 202. The sealing glue strip 6 is arranged along the circumferential direction of the vacuum glass 3. The sealing glue strip 6 helps to further enhance the heat insulation effect between the vacuum glass 3 and the movable window 2.

[0039] Refer to Figure 2 , heat insulation cavities 28 are formed between the outdoor-side broken bridge aluminum alloy frame 101 and the indoor-side broken bridge aluminum alloy frame 102 and the corresponding heat insulation strips 27, and between the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor-side broken bridge aluminum alloy inward-opening sash frame 202 and the corresponding heat insulation strips 27. Heat preservation cotton 7 is fixedly arranged in the heat insulation cavities 28. The heat preservation cotton 7 is EPE closed-cell foamed heat preservation material. The heat preservation cotton 7 between the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 and the indoor-side broken bridge aluminum alloy inward-opening sash frame 202 is located between the sealing glue strip 6 and the corresponding heat insulation connection glue strip 5. The heat preservation cotton 7 between the outdoor-side broken bridge aluminum alloy frame 101 and the indoor-side broken bridge aluminum alloy frame 102 is located on the side of the corresponding heat insulation connection glue strip 5 away from the movable window 2.

[0040] By using 95-series heat insulation broken bridge aluminum alloy profiles with ultra-low energy consumption for the window frame 1 and the movable window 2 and matching multiple layers of heat preservation vacuum glass 3, the heat insulation and sealing performance can be improved; meanwhile, the glass glue strips 4, heat insulation connection glue strips 5, sealing glue strips 6, and heat preservation cotton 7 can further conduct heat insulation and sealing, thus helping to meet the requirements of passive ultra-low energy consumption buildings for external windows.

[0041] Refer to Figure 2 and Figure 3, a fixing plate 8 is provided on the lower horizontal edge of the outdoor-side broken-bridge aluminum alloy inward-opening sash frame 201 away from the indoor-side broken-bridge aluminum alloy inward-opening sash frame 202. The length direction of the fixing plate 8 is arranged horizontally, and the length direction of the fixing plate 8 is parallel to the plane where the movable window 2 is located. The fixing plate 8 is located between the vacuum glass 3 and the outdoor-side broken-bridge aluminum alloy frame 101, so that the fixing plate 8 is located above the lower horizontal edge of the outdoor-side broken-bridge aluminum alloy frame 101 and is not likely to interfere with the opening and closing of the movable window 2.

[0042] Refer to Figure 2 and Figure 3 , a sliding groove 9 is formed in the bottom wall of the fixing plate 8. The depth direction of the sliding groove 9 is parallel to the width direction of the fixing plate 8. A rain receiving box 10 is slidably arranged in the sliding groove 9. The rain receiving box 10 slides into or out of the sliding groove 9 in a direction close to or away from the sliding groove 9. The sliding direction of the rain receiving box 10 is parallel to the depth direction of the sliding groove 9. A guiding groove 24 is formed in the inner wall of the sliding groove 9 away from the outdoor-side broken-bridge aluminum alloy inward-opening sash frame 201. The length direction of the guiding groove 24 is parallel to the sliding direction of the rain receiving box 10. A guiding block 25 is slidably arranged in the guiding groove 24. The guiding block 25 is fixedly connected to the side of the rain receiving box 10 away from the outdoor-side broken-bridge aluminum alloy inward-opening sash frame 201. The sliding fit between the guiding block 25 and the guiding groove 24 guides the sliding of the rain receiving box 10.

[0043] Refer to Figure 2 and Figure 3 , the longitudinal section of the rain receiving box 10 is V-shaped. The side of the rain receiving box 10 close to the outdoor-side broken-bridge aluminum alloy inward-opening sash frame 201 is arranged to be inclined, and the distance from the side of the rain receiving box 10 close to the outdoor-side broken-bridge aluminum alloy inward-opening sash frame 201 to the side of the fixing plate 8 away from the outdoor-side broken-bridge aluminum alloy inward-opening sash frame 201 gradually decreases in the direction away from the vacuum glass 3. An outlet hole 11 is formed in the side of the rain receiving box 10 away from the outdoor-side broken-bridge aluminum alloy inward-opening sash frame 201. The outlet hole 11 is located at the lower end of the rain receiving box 10, and the diameter of the outlet hole 11 is 1-2 mm.

[0044] Refer to Figure 2 and Figure 3, on one side of the fixed plate 8 close to the guiding groove 24, a rain inlet 12 is provided. The rain inlet 12 is located above the guiding groove 24 and is communicated with the sliding groove 9. The rain inlet 12 is located above the rain receiving box 10. The length direction of the rain inlet 12 is parallel to the length direction of the fixed plate 8. The cross-section of the rain inlet 12 is larger than the cross-section of the water outlet hole 11. A waterproof cloth 14 is fixed along the circumferential direction of the top wall of the rain receiving box 10. The waterproof cloth 14 is located above the rain receiving box 10. One side of the waterproof cloth 14 away from the rain receiving box 10 is fixed on the inner wall of the sliding groove 9. The waterproof cloth 14 is located below the rain inlet 12, so that the waterproof cloth 14 blocks the gap between the rain receiving box 10 and the inner wall of the sliding groove 9. When the rain receiving box 10 is located in the sliding groove 9, the waterproof cloth 14 is in a relaxed state, thus facilitating the rain receiving box 10 to slide out of the sliding groove 9.

[0045] Refer to Figure 3 and Figure 4 , in the sliding groove 9, a pulling member for pulling the rain receiving box 10 to slide towards the direction close to the sliding groove 9 is provided. To facilitate pulling the rain receiving box 10 to slide towards the direction close to the sliding groove 9, the pulling member includes an elastic cord 13 for pulling the rain receiving box 10 to slide towards the direction close to the sliding groove 9. The elastic cord 13 is located outside the waterproof cloth 14. Two elastic cords 13 are symmetrically arranged along the center line of the rain receiving box 10. One end of the elastic cord 13 is fixedly arranged on the inner wall of the sliding groove 9, and the other end is fixedly connected to the top wall of the rain receiving box 10. In other embodiments, the elastic cord 13 can be replaced by a tension spring.

[0046] When it rains, rainwater flows into the sliding groove 9 from the rain inlet 12 along the fixed plate 8 and flows into the rain receiving box 10 through the guiding of the waterproof cloth 14. Since the cross-section of the water outlet hole 11 is much smaller than the cross-section of the rain inlet 12, as the amount of rainwater in the rain receiving box 10 increases, under the action of gravity, the rain receiving box 10 drives the guiding block 25 to slide away from the rain inlet 12. The rain receiving box 10 gradually moves out of the sliding groove 9 and extends to the connection between the movable window 2 and the window frame 1. At this time, a small amount of water flows out through the water outlet hole 11. Since the rain receiving box 10 is inclined, it can divert the flowing rainwater, so that the rainwater is not easily infiltrated into the overlapping part of the movable window 2 and the window frame 1. When the rain stops and all the rainwater in the rain receiving box 10 is completely discharged through the water outlet hole 11, the stretched elastic cord 13 pulls the rain receiving box 10 to slide towards the direction close to the sliding groove 9, so that the rain receiving box 10 slides into the sliding groove 9 and does not easily affect the opening of the movable window 2.

[0047] Refer to Figure 2 and Figure 5, a rotating shaft 15 is fixedly inserted through one side of the fixing plate 8 close to the vacuum glass 3. A base 26 is fixed to one side of the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 close to the fixing plate 8. The rotating shaft 15 is rotatably arranged on the base 26. The rotation axis of the rotating shaft 15 is parallel to the length direction of the fixing plate 8. The rotating shaft 15 drives the fixing plate 8 to rotate towards or away from the vacuum glass 3. A torsion spring 17 is movably sleeved on the rotating shaft 15. One end of the torsion spring 17 is fixedly connected to the fixing plate 8, and the other end is fixedly connected to the base 26. The torsion spring 17 is used to drive the fixing plate 8 to rotate towards the direction close to the vacuum glass 3.

[0048] Referring to Figure 2 and Figure 3 , a water-proof connecting cloth 16 is fixedly connected between one side of the fixing plate 8 close to the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 and the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201. The water-proof connecting cloth 16 has no elasticity. The water-proof connecting cloth 16 is used to pull the fixing plate 8 into abutment with the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201. When the fixing plate 8 is in the initial state, the fixing plate 8 abuts against the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201. At the same time, the water-proof connecting cloth 16 can prevent rainwater from easily penetrating along the gap between the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201 and the fixing plate 8.

[0049] Referring to Figure 2 and Figure 3 , a storage cavity 18 is formed on one side of the fixing plate 8 close to the rain inlet 12. The storage cavity 18 is located on the side of the rain inlet 12 close to the rotating shaft 15. A fire-proof board 19 is slidably arranged in the storage cavity 18. The longitudinal section of the fire-proof board 19 is quadrilateral. The fire-proof board 19 is used to abut against the glass seal strip 4 on the side close to the outdoor-side broken bridge aluminum alloy inward-opening sash frame 201. A sealing film 20 for sealing the storage cavity 18 is adhered to the fixing plate 8. The melting point of the sealing film 20 is lower than the melting point of the glass seal strip 4. The melting point of the water-proof connecting cloth 16 is lower than the melting point of the sealing film 20. Fire-proof sand is stored in the storage cavity 18.

[0050] Referring to Figure 2 and Figure 3 , a pushing member for pushing the fire-proof board 19 to slide away from the storage cavity 18 is arranged in the storage cavity 18. The pushing member includes a spring 21 for pushing the fire-proof board 19 to slide away from the storage cavity 18. The spring 21 is located on the side of the fire-proof board 19 away from the sealing film 20. One end of the spring 21 is fixedly connected to the bottom wall of the storage cavity 18, and the other end is fixedly connected to the side of the fire-proof board 19 away from the sealing film 20.

[0051] When a fire breaks out on an adjacent floor and the fire spreads upwards from the outside, as the temperature rises, the water-blocking connecting cloth 16 first melts. At this time, the tension of the water-blocking connecting cloth 16 on the fixed plate 8 decreases. Then, the deformed torsion spring 17 drives the fixed plate 8 to rotate towards the direction close to the vacuum glass 3, so that the side of the fixed plate 8 away from the rotating shaft 15 abuts against the vacuum glass 3, which can support the vacuum glass 3. Then, as the temperature continues to rise, the sealing film 20 begins to melt. Then, the compressed spring 21 pushes the fireproof board 19 to slide away from the storage cavity 18, so that the fireproof board 19 blocks the glass sealant strip 4, and the fireproof sand falls to the fireproof board 19 and the glass sealant strip 4, thereby being able to protect the outer glass sealant strip 4, making it difficult for the glass sealant strip 4 to melt and cause the vacuum glass 3 to become loose, and improving safety and fire resistance to a certain extent.

[0052] The implementation principle of the embodiment of the present application is as follows: Both the window frame 1 and the movable window 2 adopt 95-series heat-insulating broken-bridge aluminum alloy profiles with ultra-low energy consumption, and then are matched with multiple layers of insulating vacuum glass 3, which can improve the heat-insulating and sealing performance of the outer window; at the same time, the glass sealant strip 4, the heat-insulating connecting sealant strip 5, the sealing sealant strip 6 and the heat-insulating cotton 7 can further achieve heat-insulating and sealing, thereby helping to meet the requirements of the passive ultra-low energy consumption building for the outer window.

[0053] When it rains, rainwater flows into the rain collecting box 10 from the rain inlet 12 along the fixed plate 8. As the amount of rainwater in the rain collecting box 10 increases, the rain collecting box 10 gradually slides away from the rain inlet 12, so that the lower end of the rain collecting box 10 gradually moves out of the sliding groove 9 and extends to the connection between the movable window 2 and the window frame 1. Since the rain collecting box 10 is inclined, it can guide the flowing rainwater, making it difficult for the rainwater to penetrate into the overlapping part of the movable window 2 and the window frame 1.

[0054] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
