[0030] As shown in Figure 1 The door and window assembly 1 is arranged in the inner side of the fixed frame 7 in a rectangular frame structure, two door and window assemblies 1 are arranged and connected by the connecting profile 8, the inner side of the fixed frame 7 is further provided with a vestibule 71 between the two door and window assemblies 1, so as to ensure the structure strength of the fixed frame 7 and the heat insulation performance of the door and window assembly 1, the two door and window assemblies 1 are a window frame assembly and a window sash assembly respectively, the window frame assembly is fixed in the inner side of the fixed frame 7, and the window sash assembly rotates in the inner side of the fixed frame 7.

[0031] The glass 11 in the door and window assembly 1 is provided with three along the thickness direction of the glass 11, and two hollow cavities 13 are formed between each two adjacent glass 11 by the sealing unit 12. The glass 11 adjacent to the indoor side has an indoor surface 14 away from the hollow cavity 13, and the glass 11 adjacent to the outdoor side has an outdoor surface 15 away from the hollow cavity 13.

[0033] Further improvement is that at least two of the indoor assembly 2 adjacent to the indoor surface 14, the outdoor assembly 4 adjacent to the outdoor surface 15, and the heat insulation assembly 3 adjacent to the circumferential outer edge of the door and window assembly 1 are provided with the second thermal insulation cotton 5.

[0034] Specifically, the indoor assembly 2 adjacent to the indoor surface 14, the outdoor assembly 4 adjacent to the outdoor surface 15, and the heat insulation assembly 3 adjacent to the circumferential outer edge of the door and window assembly 1 are all provided with the second thermal insulation cotton 5. After the above structure, the second thermal insulation cotton 5 is arranged on the inner bottom wall and the two inner side walls of the groove, the number of the second thermal insulation cotton 5 is increased, and the second thermal insulation cotton 5 at the three places is respectively sealed and connected with one of the indoor surface 14, the outdoor surface 15 of the door and window assembly 1, and the circumferential outer edge of the door and window assembly 1, thereby increasing the number of sealing nodes, and the air flow is blocked by the plurality of second thermal insulation cotton 5 to reduce the heat transfer, thereby further enhancing the heat preservation and insulation performance of the door and window structure.

[0035] Further improvement is that the second thermal cotton 5 sealingly connected with the circumferential outer edge of the door and window assembly 1, and the side adjacent to the door and window assembly 1 is a sawtooth surface. Through the design of the sawtooth surface, the roughness of the side of the second thermal cotton 5 adjacent to the outer side wall of the door and window assembly 1 is increased, so that after the second thermal cotton 5 abuts against the outer side wall of the door and window assembly 1, multiple heat insulation through holes are formed to block the transmission of heat, further enhancing the thermal insulation performance of the door and window structure, and achieving energy saving.

[0036] Further improvement is that the first thermal cotton 32 and / or the second thermal cotton 5 is thermal closed-cell sponge.

[0037] Specifically, the first thermal cotton 32 and the second thermal cotton 5 are both thermal closed-cell sponge.

[0038] Compared with PE foam, thermal closed-cell sponge has more advantages in thermal insulation performance, which mainly includes the following:

[0039] First, excellent thermal insulation performance: thermal closed-cell sponge has a unique closed-cell structure, which can effectively prevent air convection and heat conduction, thereby significantly reducing heat transfer and loss. The thermal conductivity of closed-cell sponge is lower, which can maintain room temperature stability while reducing the influence of external temperature on indoor environment, thereby improving indoor environment in winter and blocking external high temperature in summer;

[0040] Second, wide application range: thermal closed-cell sponge can be flexibly applied to different surfaces, showing high customization and adaptability. Thermal closed-cell sponge can be made into various shapes and sizes, and installed on the inner wall of the thermal cavity 33 and the clamping groove, to meet the thermal insulation needs of different positions, making the application of thermal closed-cell sponge more flexible and convenient;

[0041] Third, other advantages: the closed-cell structure of thermal closed-cell sponge can endow it with excellent waterproof and moisture-proof performance, thereby preventing water vapor from entering the clamping groove and further reducing the water vapor entering the hollow cavity 13 of the door and window assembly 1, so as to ensure the dryness of the hollow cavity 13 and achieve energy saving. The elastic property of thermal closed-cell sponge enables it to have a buffering function and absorb impact force, so as to withstand the gravity and pressure of the door and window assembly 1 while avoiding damage to the door and window assembly 1.

[0042] Further improvement is that the thermal insulation reinforcing profile 31 is a PA66-GF25 profile.

[0043] PA66-GF25 is a kind of nylon material, specifically, it is a kind of engineering plastic modified by adding 25% glass fiber (GF25) in polyamide 66 (PA66) thermoplastic resin, which not only inherits the excellent performance of nylon 66, but also further improves the strength, rigidity and weather resistance through the reinforcing effect of glass fiber, so as to meet more complex and severe use environment. Specifically, since 25% glass fiber is added in PA66-GF25, the tensile strength of the material is significantly improved, the connection strength is high, the mechanical property is strong, the tensile strength can reach more than 80Mpa, and it also has the advantages of high thermal deformation capacity, high impact resistance, aging resistance, high temperature resistance and the like. In addition, it has strong self-extinguishing performance and is not easy to burn when encountering fire, and has flame retardance, so that the structural strength is significantly improved compared with polyurethane.

[0044] Moreover, PA66-GF25 also has good heat insulation performance, and the thermal conductivity value is low, which can effectively reduce the heat transfer and achieve the effect of heat insulation and heat preservation. In addition, the thermal expansion coefficient of the heat insulation reinforcing profile 31 is similar to that of the aluminum profile, and the indoor profile 22 and the outdoor profile 42 in the door and window assembly 1 in the utility model are both made of aluminum profile. After the above design, it is ensured that the heat insulation reinforcing profile 31 can still be closely combined with the indoor profile 22 and the outdoor profile 42 made of aluminum material under the condition of high temperature difference environment (such as sunlight exposure and severe cold freezing state), and will not be deformed, so as to reduce the gap and block the heat transfer, so as to achieve excellent heat preservation and heat insulation performance, reduce energy consumption and realize energy saving.

[0045] Further improvement is that two heat insulation reinforcing profiles 31 are arranged opposite to each other in each heat insulation assembly 3, and the two sides of the two heat insulation reinforcing profiles 31 are connected with the indoor assembly 2 and the outdoor assembly 4 respectively. After the above design, the number of heat insulation reinforcing profiles 31 in the heat insulation assembly 3 is reduced, so that the heat insulation assembly 3 is more easily assembled with the indoor assembly 2 and the outdoor assembly 4, the labor intensity of workers is reduced, and the construction efficiency is improved.

[0046] Further improvement is that the indoor assembly 2 comprises an indoor clamping strip 21 sealingly connected with the indoor surface 14, and the outdoor assembly 4 comprises an outdoor clamping strip 41 sealingly connected with the outdoor surface 15, and the indoor clamping strip 21 and the outdoor clamping strip 41 are both elastic clamping strips.

[0047] The indoor clamping strip 21 and the outdoor clamping strip 41 are both elastic clamping strips, which can deform elastically to ensure that they are in close contact with the indoor surface 14 and the outdoor surface 15 of the door and window assembly 1 respectively, so as to improve the sealing performance and reduce the heat transfer.

[0048] Further improvement is that the outdoor clamping strip 41 comprises an integrally connected rubber strip and heat preservation strip 412; wherein the rubber strip is a ternary ethylene-propylene rubber strip 411, and the heat preservation strip 412 is a ternary ethylene-propylene rubber and heat preservation cotton mixed foaming strip.

[0049] The outdoor clamping strip 41 is a mixture of the ethylene-propylene-diene rubber strip 411 and the heat preservation strip 412, the heat preservation strip 412 is formed by mixing ethylene-propylene-diene rubber and heat preservation cotton and then foaming, so that the outdoor clamping strip 41 can consider sealing and heat preservation, after the ethylene-propylene-diene rubber and the heat preservation cotton are mixed and foamed, the addition of the heat preservation cotton can change the physical structure and elasticity of the mixture to a certain extent, so that the mixture, that is, the outdoor clamping strip 41, still has elasticity to ensure the basis of sealing, and the addition of the heat preservation cotton makes the heat preservation and insulation performance of the mixture significantly improved, specifically, during the foaming process, the mixed heat preservation cotton can further increase the porosity inside the mixture, thereby improving the heat preservation and insulation effect.

[0050] Therefore, compared with the clamping strip made of pure ethylene-propylene-diene rubber, the clamping strip formed by mixing and foaming ethylene-propylene-diene rubber and heat preservation cotton can consider its sealing performance and heat preservation performance, further reduces the heat transfer, thereby significantly improves the heat preservation and insulation performance of the door and window structure, reduces energy consumption, and realizes energy saving.

[0051] The above is only the preferred embodiment of the utility model, it should be pointed out that, for ordinary skilled person in the art, without departing from the technical principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the utility model.
