There is an urgent need for a light, high-strength, good corrosion-resistant, and heat-insulating environment-friendly and energy-saving door and window. Content of the Utility Model:

[0014] The beneficial effects of the present utility model are as follows: The present utility model provides an environment-friendly and energy-saving door and window adopting a broken bridge structure, including an aluminum alloy frame and a glass assembly arranged in the aluminum alloy frame. The aluminum alloy frame includes an outer aluminum profile, an inner aluminum profile, and at least two heat insulation connecting frames arranged between the outer aluminum profile and the inner aluminum profile. One end of each heat insulation connecting frame is respectively connected to the outer aluminum profile, and the other end of each heat insulation connecting frame is respectively connected to the inner aluminum profile.

[0015] Compared with the aluminum alloy frame of the existing traditional doors and windows in the past, which is made of an integral pure aluminum alloy profile, the aluminum alloy frame of the present utility model adopts the structural form of an outer aluminum profile and an inner aluminum profile, and a heat insulation connecting frame with lower thermal conductivity is arranged between the outer aluminum profile and the inner aluminum profile to form a thermal broken bridge structure, which can well prevent the heat of the outer aluminum profile from being transferred to the inner aluminum profile. Compared with ordinary heat insulation rubber strips, the EPDM composite foaming rubber strip contains a large number of microbubbles inside and has a honeycomb-like porous structure inside. It is not only lower in density and lighter as a whole, but also the gas in the foaming structure has a lower thermal conductivity, which can effectively reduce heat transfer and can better prevent the heat of the outer aluminum profile from being transferred to the inner aluminum profile, thereby being able to well improve the heat insulation performance of the doors and windows; The present utility model is not only relatively light as a whole, has high strength, has good corrosion resistance, but also can effectively block the heat outside from entering the room, reduce the load of air conditioning refrigeration, and improve the energy-saving effect.

[0018] Explanation of reference numerals in the drawings: aluminum alloy frame 1, outer aluminum profile 11, hook groove part 111, inner aluminum profile 12, heat insulation connecting frame 13, convex part 131, hollow through groove 132, ethylene propylene diene monomer (EPDM) composite foamed rubber strip 14, glass assembly 2, outer layer glass 21, inner layer glass 22, heat insulation cavity 23. Specific implementation manners:
[0019] The following further describes the present utility model in conjunction with the accompanying drawings. As Figure 1-2 shown, the present utility model includes an aluminum alloy frame 1 and a glass assembly 2 disposed in the aluminum alloy frame 1. The aluminum alloy frame 1 includes an outer aluminum profile 11, an inner aluminum profile 12, and at least two heat insulation connecting frames 13 disposed between the outer aluminum profile 11 and the inner aluminum profile 12. One end of each heat insulation connecting frame 13 is respectively connected to the outer aluminum profile 11, and the other end of each heat insulation connecting frame 13 is respectively connected to the inner aluminum profile 12. An ethylene propylene diene monomer (EPDM) composite foamed rubber strip 14 is respectively disposed between every two adjacent heat insulation connecting frames 13. The front end of the EPDM composite foamed rubber strip 14 abuts against the outer aluminum profile 11, the rear end of the EPDM composite foamed rubber strip 14 abuts against the inner aluminum profile 12, and the top and bottom ends of the EPDM composite foamed rubber strip 14 respectively abut against the heat insulation connecting frame 13. Compared with the aluminum alloy frame 1 of conventional existing traditional doors and windows made of an integral pure aluminum alloy profile, the aluminum alloy frame 1 of the present utility model adopts the structural form of an outer aluminum profile 11 and an inner aluminum profile 12, and a heat insulation connecting frame 13 with relatively low thermal conductivity is disposed between the outer aluminum profile 11 and the inner aluminum profile 12 to form a thermal break structure, which can well prevent the heat of the outer aluminum profile 11 from being transferred to the inner aluminum profile 12. Compared with ordinary heat insulation rubber strips, the EPDM composite foamed rubber strip 14 contains a large number of tiny air bubbles inside and has a honeycomb-like porous structure inside. It is not only lower in density and lighter as a whole, but also the gas in the foamed structure has a lower thermal conductivity, which can effectively reduce heat transfer and can better prevent the heat of the outer aluminum profile 11 from being transferred to the inner aluminum profile 12, thereby being able to well improve the heat insulation performance of the doors and windows. The present utility model is not only relatively light as a whole, has high strength, has good corrosion resistance, but also can effectively block the heat outside from entering the room, reduce the load of air conditioning refrigeration, and improve the energy-saving effect.
[0020] The glass assembly 2 includes an outer layer glass 21, an inner layer glass 22, and a heat insulation cavity 23 disposed between the outer layer glass 21 and the inner layer glass 22. The heat insulation cavity 23 is filled with an inert gas. The inert gas in this embodiment is argon, which can effectively isolate the indoor and outdoor temperature difference.
[0021] The outer layer of glass 21 is LOW-E glass, which can reflect about 80% of the heat energy and ultraviolet rays back. It can not only effectively block ultraviolet rays and reduce radiation, but also effectively block the heat from the outside from entering the room, reduce the load of air-conditioning refrigeration, and improve the energy-saving effect.
[0022] The inner layer of glass 22 is tempered glass, which has high strength, better thermal stability, can withstand a higher temperature difference, and is not easy to break.
[0023] The heat insulation connecting frame 13 is made of rigid polyvinyl chloride plastic. It not only has low thermal conductivity and can well reduce the heat transfer of the outer aluminum profile 11 to the inner aluminum profile 12, but also has a hard texture, high mechanical strength, and more guaranteed overall structural strength.
[0024] The outer aluminum profile 11 and the inner aluminum profile 12 are respectively formed with hook groove parts 111. The two ends of the heat insulation connecting frame 13 are respectively formed with convex parts 131 that cooperate with the hook groove parts 111. The two convex parts 131 of the heat insulation connecting frame 13 are respectively clamped with the hook groove parts 111 of the outer aluminum profile 11 and the hook groove parts 111 of the inner aluminum profile 12. The outer aluminum profile 11, the inner aluminum profile 12, and the heat insulation connecting frame 13 are connected by a clamping method, which is not only more convenient to connect, but also more firm.
[0025] The heat insulation connecting frame 13 is formed with a number of hollow through grooves 132, which can not only further reduce the overall mass, but also further improve the heat insulation performance.
[0026] The longitudinal cross-sectional shape of the hollow through groove 132 is an isosceles trapezoid or an isosceles triangle. In this embodiment, the longitudinal cross-sectional shape of the hollow through groove 132 is an isosceles trapezoid. Of course, in other embodiments, the longitudinal cross-sectional shape of the hollow through groove 132 can also be other shapes.
[0027] Of course, the above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics, and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
