Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 6 , the present invention provides a technical solution: a broken bridge aluminum window, including an aluminum window frame 1, a broken bridge aluminum middle stile 2, coated glass 3, a heat preservation layer 5 and an installation groove 8, and a sealing assembly 4 is arranged on one side of the aluminum window frame 1 close to the coated glass 3.

[0030] The heat preservation layer 5 is arranged in the inner cavity of the broken bridge aluminum middle stile 2, and an energy-saving auxiliary frame 7 is installed on one side of the aluminum window frame 1.

[0031] The sealing assembly 4 includes a mounting plate 41 and an auxiliary sealing strip 44. A fixing seat 42 is fixedly connected to the side of the mounting plate 41 away from the aluminum window frame 1. An adjusting rod 43 is installed inside the fixing seat 42. The bottom end of the adjusting rod 43 passes through the fixing seat 42 and is rotatably connected to the top of the auxiliary sealing strip 44. A connecting plate 45 is rotatably connected to the middle of the side of the auxiliary sealing strip 44 away from the aluminum window frame 1.

[0032] Among them, a compression spring 47 is fixedly installed on the side of the auxiliary sealing strip 44 close to the connecting plate 45. One end of the compression spring 47 away from the auxiliary sealing strip 44 is fixedly connected to the middle of the connecting plate 45. A pressing roller 46 is fixedly connected to the end of the connecting plate 45 away from the auxiliary sealing strip 44.

[0033] Among them, a blocking block 49 is fixedly connected to the bottom of the side of the auxiliary sealing strip 44 close to the connecting plate 45, and the blocking block 49 is attached to the connecting plate 45.

[0034] The mounting plate 41 is fixed to the aluminum window frame 1 by bolts. The fixing seat 42 is located above the auxiliary sealing strip 44. There are no less than two fixing seats 42, and the adjusting rod 43 is threadedly connected to the fixing seat 42.

[0035] The auxiliary sealing strip 44 is arranged in an L shape. The side of the auxiliary sealing strip 44 close to the aluminum window frame 1 is fitted with the aluminum window frame 1. The compression springs 47 are arranged symmetrically up and down, and there are no less than two compression springs 47.

[0036] A limiting plate 48 is fixedly connected to the lower part of the side of the aluminum window frame 1 close to the auxiliary sealing strip 44. The limiting plates 48 are arranged symmetrically and are located at both ends of the auxiliary sealing strip 44. The limiting plates 48 are fitted with the auxiliary sealing strip 44.

[0037] By setting the sealing assembly 4, during use, by turning the adjusting rod 43, the adjusting rod 43 rotates adaptively inside the fixed seat 42, causing the adjusting rod 43 to descend. The adjusting rod 43 then drives the auxiliary sealing strip 44 to press downwards. The limiting plates 48 at both ends limit the auxiliary sealing strip 44 to keep the auxiliary sealing strip 44 pressing down smoothly. The auxiliary sealing strip 44 will drive the connecting plate 45 and the pressing roller 46 on one side to press downwards. The pressing roller 46 first contacts the coated glass 3. Due to the blocking of the blocking block 49, the pressing roller 46 rotates towards the side away from the aluminum window frame 1 and stretches the compression spring 47 until the auxiliary sealing strip 44 presses tightly against the top of the coated glass 3. At this time, the elastic force of the compression spring 47 tightens the pressing roller 46, making the pressing roller 46 and the auxiliary sealing strip 44 form a triangle, improving the pressing stability of the auxiliary sealing strip 44. The auxiliary sealing strip 44 facilitates the auxiliary sealing of the connection part of the coated glass 3, reduces the entry of rainwater, improves the heat preservation performance, and solves the problems of the existing broken bridge aluminum window with low heat preservation performance and poor sealing performance, thus affecting the heat preservation and energy-saving effect of the house.

[0038] A connecting block 6 is fixedly connected between the aluminum window frame 1 and the energy-saving auxiliary frame 7. The connecting block 6 is fixedly connected to the energy-saving auxiliary frame 7 through bolts. The energy-saving auxiliary frame 7 is snap-fitted with the installation groove 8. The energy-saving auxiliary frame 7 is installed on the wall through plastic expansion bolts 9.

[0039] A filler 10 is arranged between the gaps of the energy-saving auxiliary frame 7 and the installation groove 8. A waterproof and breathable film 11 is arranged at the connection part of the installation groove 8 and the energy-saving auxiliary frame 7. A sealing part 12 is arranged at the installation position of the broken bridge aluminum mullion 2 close to the wall. The filler 10 is made of polyurethane foam. The sealing part 12 is silicone sealant. There are many gaps between the outer window and the wall, between the profile and the glass, and in the cavity of the profile. The gas convects here for heat exchange between indoors and outdoors. By filling the heat preservation layer 5, the heat exchange caused by gas convection is reduced. At the same time, the filler 10 can be filled between the window frame and the cavity, and the sealing materials such as the waterproof and breathable film 11 can be pasted at the same time to improve the overall sealing performance and facilitate further improvement of the heat preservation performance.

[0040] It is provided with a heat-insulating layer 5, a filling material 10, a waterproof and breathable film 11 and a sealing part 12. The window sash material of the aluminum window frame 1 can be made of glass fiber-reinforced polyurethane or glass fiber-reinforced unsaturated resin, which has good heat-insulating performance and extremely high strength. Moreover, the above materials all use glass fiber as the reinforcing material and have a structural similarity to PA66, and can be made into heat-insulating strips, and combined with aluminum through a strip-passing device to form a broken bridge aluminum profile.

[0041] Working principle:

[0042] Before using this kind of broken bridge aluminum window, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 6 As shown, when in use, by turning the adjusting rod 43, the adjusting rod 43 rotates adaptively inside the fixed seat 42, causing the adjusting rod 43 to descend. The adjusting rod 43 then drives the auxiliary sealing strip 44 to press downwards. The limiting plates 48 at both ends limit the auxiliary sealing strip 44 to ensure that the auxiliary sealing strip 44 can be smoothly pressed down. The auxiliary sealing strip 44 will drive the connecting plate 45 and the pressing roller 46 on one side to press downwards, and the pressing roller 46 first contacts the coated glass 3.

[0043] Due to the blocking of the blocking block 49, the pressing roller 46 rotates towards the side away from the aluminum window frame 1 and stretches the compression spring 47 until the auxiliary sealing strip 44 presses tightly against the top of the coated glass 3. At this time, the elastic force of the compression spring 47 tightens the pressing roller 46, making the pressing roller 46 and the auxiliary sealing strip 44 form a triangle, improving the pressing stability of the auxiliary sealing strip 44. The auxiliary sealing strip 44 is convenient for auxiliary sealing at the connection of the coated glass 3.

[0044] By filling the heat-insulating layer 5, the heat exchange caused by gas convection is reduced; at the same time, the filling material 10 can be filled between the window frame and the cavity, and sealing materials such as the waterproof and breathable film 11 can be pasted at the same time to improve the overall sealing performance and facilitate further improvement of the heat-insulating performance.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
