By adding heat-insulating nylon between the inner and outer layers of aluminum alloy, this kind of broken-bridge aluminum alloy profile blocks the heat conduction path and improves the heat preservation performance of the window.

[0003] After retrieval, in the prior art, most of the many types of broken-bridge aluminum alloy windows achieve the purpose of increasing sealing and improving heat preservation performance through the structure mentioned in the Chinese Patent Publication No. CN210768439U, Patent Name: Sealing Structure for Doors and Windows. Its main structure includes end face profiles, indoor profiles, outdoor profiles, glass installation profiles, inner glass plates, outer glass plates, and multiple inner sealing strips, outer sealing strips, and sealants.

[0036] Preferably, in any of the above solutions, the linkage seal includes a multi-groove sealing strip 12. On one side of the multi-groove sealing strip 12 facing each of the tempered glasses 2, corresponding glass clamping grooves 13 are respectively provided. Each of the glass clamping grooves 13 is respectively clamped and connected to the corresponding end part of the corresponding tempered glass 2. On the inner and outer sides of the multi-groove sealing strip 12, safety sealing tongues 1201 are integrally formed respectively.

The outer safety sealing tongue 1201 extends into the space between the outer profile 7 and the tempered glass 2 and forms an outer combined seal with the external sealing strip 9.

[0040] Preferably, in any of the above solutions, a central profile 19 is provided in the middle of the heat insulation cavity. The central profile 19 divides the heat insulation cavity into the inner sound insulation and heat insulation cavity 15 and the outer sound insulation and heat insulation cavity 16. Inner heat insulation strips 20 are respectively installed on both sides of the inner sound insulation and heat insulation cavity 15. The two sides of the inner heat insulation strip 20 are respectively clamped in the corresponding card slots on the outer side of the inner profile 6 and the corresponding card slots on the inner side of the central profile 19. Outer heat insulation strips 21 are respectively installed on both sides of the outer sound insulation and heat insulation cavity 16. The two sides of the outer heat insulation strip 21 are respectively clamped in the corresponding card slots on the inner side of the outer profile 7 and the corresponding card slots on the outer side of the central profile 19.

[0041] Preferably, in any of the above solutions, an inner thermal insulation and sound insulation cotton 22 is installed inside the inner sound insulation and heat insulation cavity 15, and an outer thermal insulation and sound insulation cotton 23 is installed inside the outer sound insulation and heat insulation cavity 16.

[0042] Preferably, in any of the above solutions, a central heat insulation component is installed inside the central sound insulation and heat insulation cavity 17. The central heat insulation component, the inner thermal insulation and sound insulation cotton 22, and the outer thermal insulation and sound insulation cotton 23 form a three-layer heat insulation and sound insulation structure.

[0043] Inside the heat insulation cavity, the central profile 19 can divide the inner sound insulation and heat insulation cavity 15 for installing the inner thermal insulation and sound insulation cotton 22 and the outer sound insulation and heat insulation cavity 16 for installing the inner thermal insulation and sound insulation cotton 22, so as to achieve the purpose of rapid heat insulation and sound insulation. At the same time, installing a central heat insulation component inside the central sound insulation and heat insulation cavity 17 can further enhance the heat insulation effect.

[0044] Preferably, in any of the above solutions, an inner side cavity 24 is provided on the side of each inner sound insulation and heat insulation cavity 15 facing the wall, an outer side cavity 25 is provided on the side of each outer sound insulation and heat insulation cavity 16 facing the wall, a wall connecting profile 26 is provided on one side of the end of the central profile 19. Lateral clamping strips 27 that are integrally formed on both the inner and outer sides of the wall connecting profile 26 and are matched with the card slots on the corresponding inner profile 6 and outer profile 7 are provided. A central clamping strip 28 is integrally formed on one side of the end of the central profile 19. The central clamping strip 28 is clamped in the middle groove integrally formed on the inner side of the wall connecting profile 26. The inner side of the central clamping strip 28 forms the inner side cavity 24, and the outer side forms the outer side cavity 25.

[0046] Compared with the traditional three - cavity structure, it has better sound insulation and heat preservation effects, so that when heat is conducted inside and outside in the multi - cavity sound insulation structure, the purpose of reducing or blocking heat transfer can be achieved.

[0047] When outdoor noise is conducted inward, it can achieve a good sound insulation effect through the sound - elimination and filtration of the multi - cavity sound insulation structure; at the same time, under the action of various heat - preservation materials inside the multi - cavity sound insulation structure, it can achieve a better heat - preservation effect; among them, each heat - insulating strip can effectively achieve the purpose of heat insulation.

[0048] In any of the above - mentioned solutions, preferably, a plurality of sealing and anti - return components are evenly spaced from top to bottom inside the heat - insulating spacer cavity 8, and the sealing and anti - return components are used to control the corresponding linkage seal to tightly seal the edge of the toughened glass assembly.

[0049] Each of the sealing and anti - return components installed inside the heat - insulating spacer cavity 8 is mainly used to re - fasten the linkage seal after long - term use. After fastening, it can drive the linkage seal to continue applying force to the toughened glass assembly, so as to achieve the purpose of re - reinforcing and tightly sealing the ends of each toughened glass 2, and thus achieve the purpose of maintaining a good seal of the internal vacuum cavity 3.

[0050] In any of the above - mentioned solutions, preferably, the sealing and anti - return component includes a metal spring piece 29 that is installed inside the heat - insulating spacer cavity 8 and is arc - shaped. The inner side of the metal spring piece 29 is abutted and fixed on the inner profile 6, and the outer side of the metal spring piece 29 is abutted and fixed on the outer profile 7. A central stud 30 is integrally formed at the center of the metal spring piece 29. A pressure - bearing column 31 is screwed on the central stud 30. A plurality of ratchet teeth 32 are arranged along the axial direction on the outer side wall of the pressure - bearing column 31. The end of the pressure - bearing column 31 extends into the central sound - insulation and heat - preservation cavity 17 of the central profile 19 in a matching manner, and the ratchet teeth 32 cooperate with the ratchet holes 33 opened on the central profile 19; the central heat - preservation component arranged in the central sound - insulation and heat - preservation cavity 17 applies pressure to the pressure - bearing column 31 through translation and drives the middle side of the metal spring piece 29 to push the linkage seal.

[0051] It should be noted that: in the normal installation situation, the arc - shaped section of the metal spring piece 29 is in a state of applying force to the linkage seal. Since the central stud 30 is integrally formed at the center of the metal spring piece 29, the pressure - bearing column 31 and the ratchet teeth 32 cooperating on the central stud 30 can effectively play a positioning role, so as to keep the metal spring piece 29 tightly pressing the middle part of the linkage seal. Improve the sealing effect of the linkage seal on the vacuum cavity 3.

[0052] Preferably, in any of the above solutions, the central heat preservation component includes a first heat preservation strip 34 and a second heat preservation strip 35 that are spaced and installed in the central sound insulation and heat preservation cavity 17. A middle sealing cavity is formed between the first heat preservation strip 34 and the second heat preservation strip 35. Connecting discs 36 are respectively fixed on the opposite side surfaces of the first heat preservation strip 34 and the second heat preservation strip 35. The outer side walls of the connecting discs 36 are hermetically abutted against the peripheral side walls of the central sound insulation and heat preservation cavity 17. A pneumatic telescopic member 37 is installed between the middle sealing cavities. Two ends of the pneumatic telescopic member 37 are respectively fixedly installed at the centers of the connecting discs 36 on the corresponding sides. When the pneumatic telescopic member 37 extends, it will drive the first heat preservation strip 34 to press against the pressure-bearing column 31. A rigid pad 40 is fixedly installed on the outer side wall of the first heat preservation strip 34 facing the pressure-bearing column 31.

[0053] It should be noted that the central heat preservation component has two functions. One is to play the role of sound insulation and heat preservation inside the central sound insulation and heat preservation cavity 17. The other is to cooperate with the expansion and contraction of the pneumatic telescopic member 37 to achieve linkage, so as to push the pressure-bearing column 31 to press the metal elastic sheet 29 as a piston component, thereby improving or maintaining the tight sealing effect of the linkage seal on the ends of the vacuum cavities 3 composed of each tempered glass 2.

[0054] Preferably, in any of the above solutions, an inlet straight pipe 38 is integrally formed and connected to the inlet end of the pneumatic telescopic member 37. The inner end of the inlet straight pipe 38 passes through the inner sound insulation and heat preservation cavity 15 and extends into the inner cavity 14. A connecting valve 39 is cooperatively installed at the surface opening on the indoor side of the inner profile 6. The inner end of the connecting valve 39 is connected inside the inlet straight pipe 38. When the connecting valve 39 is in the open state and high-pressure gas is introduced into its interior, it can drive the pneumatic telescopic member 37 to extend.

[0055] Considering that after long-term use of the energy-saving window, the elasticity of the metal elastic sheet 29 inside it will be weakened. Therefore, the tight-sealing effect of the linkage seal on the ends of the three-layer tempered glass 2 will decrease. To ensure the sealing effect of the linkage seal on the ends of the vacuum cavity 3, by controlling the opening of the connecting valve 39 and then introducing high-pressure gas into its interior, the pneumatic telescopic member 37 can be driven to extend. Among them, when selecting the pneumatic telescopic member 37, a general micro cylinder can be selected, and its air inlet end is connected to the inlet straight pipe 38. When installing the inlet straight pipe 38, keep it stable and positioned. After the air pressure is injected, the tightness of the internal high-pressure gas can be ensured by closing the connecting valve 39.

[0056] Preferably, in any of the above solutions, the adjustment end of the sealing and anti-return component is located on the indoor side, which is convenient for maintenance operations.

[0057] In summary, it can be seen that the energy-saving window designed in the present invention can form a multi-chamber sound insulation structure with eight chambers after installation, which has better sound insulation and heat insulation effects compared with the traditional three-chamber structure. When the internal and external heat conducts in the multi-chamber sound insulation structure, it can reduce or block the heat transfer, with good overall heat insulation performance and energy-saving effect. After installation, the edges of the toughened glass 2 on the indoor side and the edges of the toughened glass 2 on the outdoor side can both form double seals, which can better ensure the sealing effect inside the vacuum chamber 3.

[0058] In addition, under the action of the sealing anti-return component, it can ensure that pressure is applied to the linkage seal at the corresponding position, further tightening the double-sealed part to prevent dislocation and improving the positioning and sealing effect of the linkage seal. All non-metallic parts designed inside the bridge insulation profile assembly are in a built-in state, effectively avoiding the situation of external exposure, reducing the exposed area of external non-metallic parts, and better ensuring the fire prevention effect of the entire window frame unit 1 when dealing with fires.
