Abstract
Description
Technical Field
[0001] This application relates to the field of sunroof sealing technology, and more specifically, to a double-sealed structure to prevent snow drift. Background Technology
[0002] Skylights are fixed and connected using bolts, which, while practical and flexible, also has some drawbacks. During use, the threads of the bolts are prone to wear. This is mainly because skylights are affected by various factors such as wind pressure and temperature changes, causing the bolt connections to loosen and wear. Worn threads not only reduce the tightening force of the connection but also create the risk of air and water leaks.
[0003] In view of this, we propose a double-sealed structure to prevent snow drift. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] The purpose of this application is to provide a double-sealed snow-proof structure that solves the technical problems in the background art mentioned above. It achieves the technical effect of using a thermally broken aluminum alloy structure, delivering the whole window as a finished product on site, making the skylight nail-free and glue-free, waterproof in structure, and equipped with an internal drainage system to avoid the risk of water leakage.
[0006] 2. Technical Solution
[0007] This application provides a double-sealed snow-proof structure, including a thermally broken aluminum profile, a polycarbonate sheet, a drive motor, a stroke gas strut, and a split aluminum plate base. The thermally broken aluminum profile includes a rubber strip fastener, a polycarbonate sheet fastener, wedges, and a central chamber. The rubber strip fastener and the polycarbonate sheet fastener are fixedly connected by multiple wedges. The polycarbonate sheet is fixed to the polycarbonate sheet fastener. A second EPDM sealing strip is detachably installed on the central chamber of the polycarbonate sheet fastener and on one side of the split aluminum plate base. A first EPDM sealing strip is detachably installed on both the split aluminum plate base and the central chamber. The split aluminum plate base and the thermally broken aluminum profile are hinged together.
[0008] By adopting the above technical solution, the top of the first EPDM sealing strip is firmly sealed to the top of the polycarbonate sheet, which not only blocks the water leakage channel inside the window, but also improves the airtightness of the window, playing a dual role of preventing leakage and preventing snow from drifting. The second EPDM sealing strip is firmly sealed to the bottom aluminum plate split base, blocking the convection of indoor and outdoor air, improving the airtightness of the window, and playing a dual role of preventing leakage and preventing snow from drifting.
[0009] As an optional solution to the technical solution in this application, the adhesive strip fastener is integrally formed with a C-shaped bayonet, and the second EPDM sealing strip is integrally formed with a locking strip that matches the bayonet.
[0010] By adopting the above technical solution, the insertion and cooperation of the clip and the bayonet facilitates the installation and removal of the second EPDM sealing strip and the rubber fastener. At the same time, the use of a nail-free connection method is convenient for quick installation and removal, and reduces water leakage caused by screw drilling installation.
[0011] As an optional solution to the technical solution of this application, the first EPDM sealing strip is integrally formed with a U-shaped part, and the inner side of the U-shaped part is integrally formed with multiple locking feet. The aluminum plate split base includes a Z-shaped thermally broken aluminum strip, and the Z-shaped thermally broken aluminum strip has multiple fixing foot grooves. The first EPDM sealing strip has a steel sheet inside.
[0012] By adopting the above technical solution, the U-shaped part and the Z-shaped thermal break aluminum strip are inserted and matched, and the clip is inserted into the corresponding fixing foot groove, so as to improve the fixing reliability of the Z-shaped thermal break aluminum strip and the first EPDM sealing strip. Furthermore, by embedding a steel sheet in the first EPDM sealing strip, the support strength of the first EPDM sealing strip is improved, which also facilitates the reset of the first EPDM sealing strip.
[0013] As an optional solution to the technical solution in this application, the polycarbonate sheet fastener has a pre-reserved slot adapted to the polycarbonate sheet, and butyl tape is provided between the polycarbonate sheet and the slot.
[0014] By adopting the above technical solution, the polycarbonate sheet is inserted into the slot to facilitate its assembly, and butyl tape is used to seal the polycarbonate sheet and its fasteners.
[0015] As an optional solution to the technical solution in this application, a drainage groove is reserved between the rubber strip fastener and the polycarbonate sheet fastener.
[0016] By adopting the above technical solution, when there are gaps and leaks in the polycarbonate sheet and its fasteners, the drainage channel can guide the leaking water to prevent it from seeping into the room. This internal drainage method avoids the risk of leakage.

The thermally broken aluminum profile 1 includes a rubber strip fastener 11, a polycarbonate sheet fastener 12, wedges 13, and a central atrium 14. The rubber strip fastener 11 and the polycarbonate sheet fastener 12 are fixedly connected by multiple wedges 13. The polycarbonate sheet 2 is fixed on the polycarbonate sheet fastener 12. A second EPDM sealing strip 8 is detachably installed on the central atrium 14 of the polycarbonate sheet fastener 12 and on one side of the split aluminum plate base 6. A first EPDM sealing strip 7 is detachably installed on both the split aluminum plate base 6 and the central atrium 14. The split aluminum plate base 6 and the thermally broken aluminum profile 1 are hinged together by a hinge 5.
[0031] Reference Figures 1-8 The aluminum plate split base 6 is used to fix the skylight to the wall and is hinged to the thermally broken aluminum profile 1 through the hinge 5. The thermally broken aluminum profile 1 is used to fix the polycarbonate sheet 2. The two ends of the drive motor 3 and the stroke gas strut 4 are respectively rotatably connected between the thermally broken aluminum profile 1 and the aluminum plate split base 6. The top of the first EPDM sealing strip 7 is firmly sealed to the polycarbonate sheet 2, which not only blocks the water leakage channel inside the window, but also improves the airtightness of the window, playing a dual role of preventing leakage and preventing snow. The second EPDM sealing strip 8 is firmly sealed to the lower aluminum plate split base 6, blocking the convection of indoor and outdoor air, improving the airtightness of the window, and playing a dual role of preventing leakage and preventing snow.
[0032] The rubber strip fastener 11 is integrally formed with a C-shaped bayonet 111, and the second EPDM sealing strip 8 is integrally formed with a locking strip 81 that matches the bayonet 111.
[0033] Reference Figures 6-8 The insertion and engagement of the clip 81 and the bayonet 111 facilitates the installation and disassembly of the second EPDM sealing strip 8 and the rubber fastener 11. The nail-free engagement method is adopted, which facilitates quick installation and disassembly and reduces water leakage caused by screw drilling installation.
[0034] The first EPDM sealing strip 7 is integrally formed with a U-shaped part 72. The inner side of the U-shaped part 72 is integrally formed with multiple retaining feet 73. The aluminum plate split base 6 includes a Z-shaped thermally broken aluminum strip 61. The Z-shaped thermally broken aluminum strip 61 has multiple retaining foot grooves 62. The first EPDM sealing strip 7 has a steel sheet 71 inside.
[0035] Reference Figures 2-4 The U-shaped part 72 is inserted into the Z-shaped thermal break aluminum strip 61, and the locking foot 73 is inserted into the corresponding fixing foot groove 62 to improve the fixing reliability of the Z-shaped thermal break aluminum strip 61 and the first EPDM sealing strip 7. The steel plate 71 built into the first EPDM sealing strip 7 is used to improve the support strength of the first EPDM sealing strip 7 and facilitate the reset of the first EPDM sealing strip 7.
[0036] The polycarbonate sheet fastener 12 has a pre-drilled groove 121 that is compatible with the polycarbonate sheet 2, and a butyl tape 122 is placed between the polycarbonate sheet 2 and the groove 121.

[0038] A drainage groove 131 is reserved between the rubber strip fastener 11 and the polycarbonate sheet fastener 12.
[0039] Reference Figure 2 and Figure 6 and Figure 8 When there is a gap between the polycarbonate sheet 2 and the polycarbonate sheet fastener 12 and water leakage occurs, the water can be guided through the drainage channel 131 to prevent it from seeping into the room. By using internal drainage, the risk of water leakage can be avoided.
[0040] Working principle: The thermally broken aluminum profile 1 is used to fix the polycarbonate sheet 2. The two ends of the drive motor 3 and the stroke gas strut 4 are respectively rotatably connected between the thermally broken aluminum profile 1 and the aluminum plate split base 6. The drive motor 3 retracts, pulling the rubber strip fastener 11 and the polycarbonate sheet 2 to close, and making the top of the first EPDM sealing strip 7 firmly sealed against the polycarbonate sheet 2, which not only blocks the water leakage channel inside the window, but also improves the airtightness of the window, playing a dual role of preventing leakage and preventing snow. The second EPDM sealing strip 8 firmly seals against the lower aluminum plate split base 6, blocking the convection of indoor and outdoor air, improving the airtightness of the window, and playing a dual role of preventing leakage and preventing snow.
