[0005] Through the above analysis, the problems and defects existing in the prior art are as follows: in the existing door and window frame structures, at positions such as the gaps between the window frame and the wall, and the connections between the window frame and the window sash, heat loss is likely to occur, which not only affects the heat preservation effect but may also lead to poor airtightness of the doors and windows, further exacerbating the energy consumption problem. Summary of the Utility Model
[0006] To overcome the problems existing in the related art, the utility model provides a door and window frame structure with heat insulation and heat preservation functions.
[0007] The technical solution of the utility model is as follows:

Detailed Embodiments
[0028] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0029] As Figure 1 shown, the heat - insulating door and window frame structure provided by the embodiment of the present utility model includes a fixed window frame 1, a fixed sash 2 and an opening - closing sash 3. The fixed sash 2 and the opening - closing sash 3 are both fixed inside the fixed window frame 1. A transom 4 is fixed at the upper end inside the fixed window frame 1, and a transom mullion 5 is arranged in the middle of the transom 4.
[0030] The fixed window frame 1 in the embodiment of the present utility model serves as the main body of the entire structure, responsible for carrying and fixing components such as the fixed sash 2, the opening - closing sash 3 and the transom 4, ensuring the stability of the door and window frame, and improving its service life and safety performance. Since the entire structure is designed such that the fixed window frame 1 contains the fixed sash 2 and the opening - closing sash 3, the sealing performance of the door and window frame is better, reducing the exchange of indoor and outdoor air, thereby improving the heat - insulating effect. Especially under cold or hot weather conditions, it can effectively maintain the stability of the indoor temperature.
[0031] As Figures 2 to 5 shown, a longitudinal mullion 6 is installed between the fixed sash 2 and the opening - closing sash 3 in the embodiment of the present utility model. An installation slot 8 is opened at the outer end of the fixed window frame 1. The fixed window frame 1, the fixed sash 2, the opening - closing sash 3, the longitudinal mullion 6 and the transom mullion 5 all include an outdoor - side aluminum profile 10 and an indoor - side aluminum profile 11. A heat - insulating strip 9 is clamped between the outdoor - side aluminum profile 10 and the indoor - side aluminum profile 11 of the fixed window frame 1, the fixed sash 2, the opening - closing sash 3, the longitudinal mullion 6 and the transom mullion 5. A cavity 12 is opened in the middle of the outdoor - side aluminum profile 10 and the indoor - side aluminum profile 11, and a heat - insulating layer 13 is filled in the cavity 12. Support plates 14 are respectively arranged on the indoor - side aluminum profiles 11 of the fixed window frame 1, the longitudinal mullion 6 and the transom mullion 5. Limiting grooves 15 are opened on the outdoor - side aluminum profiles 10 of the fixed sash 2, the longitudinal mullion 6 and the transom mullion 5. Limiting frames 16 corresponding to the support plates 14 are clamped in the limiting grooves 15. Opposite fixing grooves 17 are respectively opened at the outer ends of the support plates 14 and the limiting frames 16, and double - layer glass 7 is installed between the support plates 14 and the limiting frames 16.
[0032] The heat insulation strip 9 sandwiched between the outdoor aluminum profile 10 and the indoor aluminum profile 11 in the embodiment of the utility model effectively prevents the heat exchange between indoors and outdoors, improving the heat insulation and heat preservation performance of the door and window frame. The heat preservation layer 13 filled in the cavity 12 further enhances the heat insulation effect and effectively maintains the stability of the indoor temperature. The setting of the longitudinal mullion 6 strengthens the overall stability of the door and window frame, improving its wind pressure resistance and impact resistance. The cooperative design of the supporting plate 14 and the limiting frame 16 ensures the stable installation of the double-glazed glass 7 and improves the safety of the door and window frame at the same time. The sandwiching of the heat insulation strip 9 between the outdoor aluminum profile 10 and the indoor aluminum profile 11 and the installation of the double-glazed glass 7 both effectively improve the air tightness of the door and window frame, prevent air infiltration and reduce energy consumption. The limiting groove 15 opened on the outdoor aluminum profile 10 cooperates with the supporting plate 14 of the indoor aluminum profile 11, making the installation of the double-glazed glass 7 simpler and more convenient. Due to the modular design, each component of the door and window frame can be replaced or repaired separately, reducing the maintenance cost. The good heat insulation and heat preservation performance reduces energy consumption, meeting the requirements of modern building energy conservation and environmental protection.
[0033] In summary, through its unique design, the heat-insulating and heat-preserving door and window frame structure realizes excellent heat insulation and heat preservation performance, stable structural design, good air tightness, convenient installation and maintenance, and beauty and practicality, providing an efficient and energy-saving door and window solution for modern buildings.
[0034] Preferably, sealing rubber strips 18 are adhesively bonded to both sides of the double-glazed glass of the fixed sash 2 in the embodiment of the utility model. The sealing rubber strips 18 are clamped in the fixed grooves 17, and a silicone rubber layer 19 is coated on the outer side of the sealing rubber strips 18.
[0035] In the embodiment of the utility model, the sealing rubber strips 18 are closely attached to both sides of the double-glazed glass, effectively preventing air infiltration and enhancing the air tightness of the door and window frame. This is crucial for the heat insulation effect because air infiltration is one of the main reasons for heat loss. By enhancing the air tightness, the exchange of indoor and outdoor air is reduced, thereby improving the heat insulation and heat preservation performance of the door and window frame, which is of great significance for maintaining the stability of the indoor temperature in cold or hot seasons. The sealing function of the sealing rubber strips 18 not only prevents air infiltration but also effectively prevents moisture such as rainwater from entering the room, enhancing the waterproof performance of the door and window frame. The combined use of the sealing rubber strips 18 and the silicone rubber layer 19 not only enhances the sealing performance but also increases the structural stability of the door and window frame to a certain extent, improving the service life of the door and window frame.
[0036] Preferably, in the embodiments of the present utility model, on the opposite sides of the outdoor aluminum profiles 10 and the indoor aluminum profiles 11 of the fixed window frame 1, the fixed sash 2, the opening and closing sash 3, the vertical mullion 6, and the transom mullion 5, card slots 20 are provided, and the heat insulation strip 9 is clamped in the card slots 20. Through the design of the card slots 20 in the embodiments of the present utility model, the close fit between the heat insulation strip 9 and the aluminum profiles is ensured, thereby improving the sealing performance of the window and door frames, helping to prevent air infiltration, maintaining the stability of the indoor temperature, and reducing energy loss.
[0037] Preferably, in the embodiments of the present utility model, hardware fixing grooves 21 are respectively provided at the relative positions of the opening and closing sash 3 and the fixed window frame 1, and arc-shaped sealing strips 22 are respectively clamped at both ends of the inner side surface of the opening and closing sash 3. By providing the hardware fixing grooves 21 at the relative positions of the opening and closing sash 3 and the fixed window frame 1 in the embodiments of the present utility model, the stable installation of the opening and closing sash can be ensured, and the overall stability of the window and door frames is improved.
[0038] Preferably, in the embodiments of the present utility model, a rubber strip 23 is clamped in the middle edge of the double-glazed glass 7, a glass glue layer 24 is coated on the outer side of the rubber strip 23, a plurality of through holes are spaced apart on the inner side surface of the rubber strip 23, and desiccant particles are filled in the through holes. The combined use of the rubber strip 23 and the glass glue layer 24 enhances the sealing performance of the double-glazed glass 7 and improves the heat insulation effect. The through holes on the inner side of the rubber strip are filled with desiccant particles, which can effectively absorb the moisture in the air, prevent water vapor from condensing between the double-glazed glasses, and keep the glass clear and transparent.
[0039] Preferably, in the embodiments of the present utility model, arc-shaped positioning plates are respectively provided on the inner sides of the outdoor aluminum profiles 10 and the indoor aluminum profiles 11 of the vertical mullion 6 and the transom mullion 5. Through the arc-shaped positioning plates, not only the structural stability is enhanced, but also the internal thermal insulation layer can be positioned and fixed.
[0040] The working principle of the present utility model is as follows: An insulating strip 9 is clamped between the outdoor-side aluminum profile 10 and the indoor-side aluminum profile 11 in the present utility model, and a thermal insulation layer 13 is filled in the cavity 12, effectively blocking the heat transfer and improving the heat insulation performance of the window frame. This structure effectively blocks the direct heat transfer between indoors and outdoors, playing the role of "thermal break". The insulating strip 9 is clamped in the card slots 20 respectively opened on the opposite sides of the outdoor-side aluminum profile 10 and the indoor-side aluminum profile 11, ensuring the stability and heat insulation effect of the insulating strip. The double-glazed glass 7 is installed between the supporting plate 14 and the limiting frame 16 and is sealed by the sealing rubber strip 18 in the fixing groove 17, ensuring the heat insulation performance of the window. A silicone rubber layer 19 is coated on the outer side of the sealing rubber strip 18, further enhancing the sealing effect and preventing the exchange of indoor and outdoor air. The relative positions of the opening and closing fan 3 and the fixed window frame 1 are respectively provided with hardware fixing grooves 21 for installing hardware such as handles and locks, ensuring the normal opening and closing and safety of the window. Arc-shaped sealing strips 22 are respectively clamped at both ends of the inner side surface of the opening and closing fan 3. When the window is closed, these sealing strips are closely attached to the fixed window frame, preventing the infiltration of cold air. A rubber strip 23 is clamped in the middle edge of the double-glazed glass 7, and desiccant particles are filled in the through holes spaced on the inner side surface of the rubber strip. These desiccants can absorb the water vapor between the double-glazed glass, prevent condensation, and ensure the clarity and heat insulation effect of the window.
[0041] In summary, through its unique insulating strip, double-glazed glass, sealing design, hardware and other structures, the window frame structure with heat insulation achieves good heat insulation effect, improving the energy efficiency and living comfort of buildings.
