Description
Technical Field
[0001] This utility model relates to the field of thermal break windows and doors, specifically multi-layer composite thermal break windows and doors. Background Technology
[0002] Doors and windows are an important part of a building's external envelope, serving functions such as sheltering from wind and rain, heat insulation, sound insulation, lighting, and ventilation. With the improvement of people's living standards, the requirements for doors and windows in decoration are becoming increasingly higher. As products with large usage and wide application, the unique advantages of doors and windows determine their broad market prospects. While leveraging their advantages and addressing problems encountered during use, new high-performance doors and windows are beginning to enter consumers' field of vision. Aluminum alloy thermal break windows, using thermally broken aluminum profiles and double-glazed windows, feature an aluminum alloy frame divided into indoor and outdoor sections. Some alloy profiles incorporate plastic thermal break strips in the middle of the indoor and outdoor alloy profiles, resulting in excellent thermal insulation and a lighter weight. However, most existing thermally broken windows are fixed to the glass with adhesive, and the internal components are mostly made of polyvinyl chloride and nylon. Over time, the thermal break strips are subjected to temperature changes, making them prone to aging. Traditional thermally broken windows are not easy to replace, requiring the frame at the connection between the window and the wall to be disassembled, making replacement time-consuming and labor-intensive.
[0003] Based on this, we now offer multi-layer composite thermally broken windows and doors, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] Example 1
[0026] In one embodiment, such as Figures 1-7As shown, a multi-layer composite thermally broken window includes a window frame 11 and insulated glass 13. A positioning window frame 12 is fixedly installed inside the window frame 11. A fixed window frame 16 and a removable window frame 17 are respectively attached to both sides of the positioning window frame 12. The fixed window frame 16 is fixedly installed inside the window frame 11. Both insulated glass panes 13 are fixedly installed inside the mounting frame 14, with a vacuum gap between them. The outer side of the mounting frame 14 is attached tightly to the inner side of the positioning window frame 12. Symmetrically arranged first sealing mounting grooves are provided on the outer side of the mounting frame 14, each containing a first sealing strip 15. The removable window frame 17 is attached to both the positioning window frame 12 and the mounting frame 14. The frame 14 is tightly attached to one side, and the disassembly window frame 17 is provided with a fixing mechanism for fixing the installation frame 14. Both the fixed window frame 16 and the disassembly window frame 17 are provided with a second sealing installation groove. The second sealing installation groove is provided with a sealing mechanism for increasing the heat insulation and sound insulation effect at the connection between the fixed window frame 16 and the disassembly window frame 17 and the installation frame 14. The fixing mechanism facilitates the fixed connection between the disassembly window frame 17 and the positioning window frame 12, thereby fixing the installation frame 14 and facilitating the disassembly of the installation frame 14. The sealing mechanism facilitates the sealing treatment at the connection between the fixed window frame 16 and the disassembly window frame 17 and the installation frame 14, and can also increase the heat insulation and sound insulation effect.
[0027] The fixing mechanism includes a first screw 18. The disassembly window frame 17 has a plurality of first threaded holes arranged in an array. The positioning window frame 12 has second threaded holes on one side corresponding to the positions of the first threaded holes. A first screw 18 is fitted into both the first and second threaded holes coaxially. The first screw 18 has a through hole in its center. A third threaded hole is located inside the positioning window frame 12 at the end position of the second threaded holes. A second screw 19 is fitted into the third threaded hole. The first screw 18 and the second screw 19 have opposite directions of rotation. In use, when the mounting frame 14 needs to be installed, the mounting frame 14 is placed... Inside the positioning window frame 12, since the fixed window frame 16 is fixed, one side of the mounting frame 14 is tightly attached to one side of the fixed window frame 16. Then, the disassembly window frame 17 is tightly attached to the other side of the mounting frame 14. Then, the first screw 18 is installed in the first threaded hole and the second threaded hole. Then, the first screw 18 is fixed with a tool, and the second screw 19 is placed in the middle of the first screw 18. The second screw 19 is rotated so that the external thread of one end of the second screw 19 engages with the internal thread in the third threaded hole, thereby increasing the connection between the disassembly window frame 17 and the mounting frame 14, and also preventing the first screw 18 from loosening.
[0028] The sealing mechanism includes a second sealing strip 20 and a third sealing strip 21. The second sealing mounting groove is fitted with the second sealing strip 20 and the third sealing strip 21. The second sealing strip 20 and the third sealing strip 21 are connected by a snap-fit engagement. The inner side of the second sealing strip 20 is provided with a plurality of limiting strips 22. The limiting strips 22 have a semi-circular cross-section. The third sealing strip 21 is provided with limiting grooves at positions corresponding to the limiting strips 22. In use, when the second sealing strip 20 and the third sealing strip 21 need to be installed, the second sealing strip 20 and the third sealing strip 21 are snap-fitted together to form a sealing strip with flat sides. Then, one side of the third sealing strip 21 is tightly attached to one side of the mounting frame 14.
[0029] The third sealing strip 21 is made of rubber, and the second sealing strip 20 has a honeycomb structure inside. When in use, the rubber material of the third sealing strip 21 makes it easy to fit tightly against one side of the mounting frame 14, thereby increasing the sealing effect. The honeycomb structure inside the second sealing strip 20 makes it easier to increase the sound insulation effect and reduce heat loss.
[0030] Both the second sealing strip 20 and the third sealing strip 21 are rounded around their edges, and both the second sealing mounting groove and the second sealing strip 20 are rounded around their edges. In use, the second sealing strip 20 and the third sealing strip 21 are rounded around their edges, so that the second sealing strip 20 and the third sealing strip 21 do not have wrinkles caused by right-angle bends, and the overall sealing, heat insulation and sound insulation effects are good.
[0031] Positioning strips 23 are fixedly provided on both sides of the mounting frame 14. Connecting grooves are provided on one side of the fixed window frame 16 and the disassembled window frame 17 at the positions corresponding to the positioning strips 23. During use, this facilitates positioning when installing the mounting frame 14 and the disassembled window frame 17. At the same time, it can increase the sealing effect at the connection between the mounting frame 14 and the fixed window frame 16 and the disassembled window frame 17, thereby reducing the flow of hot air through the mounting frame 14.
[0032] Example 2
[0033] The difference from Embodiment 1 is that: a stop installation strip 25 is fixedly provided on all four sides of one side of the disassembled window frame 17, and a heat insulation strip 24 is closely attached to one side of the disassembled window frame 17. The heat insulation strip 24 is made of fireproof and heat-insulating material. A limiting installation groove is provided at the corresponding position of the heat insulation strip 24 and the stop installation strip 25. When it is needed to increase the heat insulation effect, the heat insulation strip 24 can be installed on one side of the disassembled window frame 17 to reduce the loss of heat in the room or prevent heat from outside from entering the room.
[0034] The above embodiments disclose multi-layer composite thermally broken windows and doors. When installing the mounting frame 14, the second sealing strip 20 and the third sealing strip 21 are snapped together. The sealing strip composed of the second sealing strip 20 and the third sealing strip 21 is placed inside the fixed window frame 16 and the disassembly window frame 17, with one side of the third sealing strip 21 tightly against one side of the mounting frame 14. The mounting frame 14 is then placed inside the positioning window frame 12. Since the fixed window frame 16 is fixedly installed, one side of the mounting frame 14 is tightly against one side of the fixed window frame 16. Subsequently, the disassembly window frame 17 is then connected to the mounting frame 14. With one side tightly attached, the first screw 18 is installed in the first threaded hole and the second threaded hole. Then, the first screw 18 is fixed with a tool, and the second screw 19 is placed in the middle of the first screw 18. The second screw 19 is rotated so that the external thread of one end of the second screw 19 engages with the internal thread of the third threaded hole, thereby increasing the connection between the disassembled window frame 17 and the installed frame 14. At the same time, it can also prevent the first screw 18 from loosening. When it is necessary to increase the heat insulation effect, the heat insulation strip 24 can be installed on the side of the disassembled window frame 17 to reduce the loss of heat from the room or prevent the outside heat from entering the room.
[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
