Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material for load-bearing rods (rods that bear and transmit deadweight and loads) and doors and windows composited with wood and plastic, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows.

[0003] In the prior art, the main function of doors and windows is to block wind and rain and provide shelter for people indoors. Therefore, the airtightness of aluminum alloy doors and windows during use is extremely important, which directly affects the use effect of doors and windows. Therefore, sealing strips are usually provided at the contact parts of window frames and window sashes to improve the airtightness of aluminum alloy windows. The sealing strips will harden after aging, and will produce wrinkles when under compression for a long time, thereby deteriorating the subsequent sealing effect of the sealing strips and affecting the use experience of doors and windows. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an aluminum alloy door and window with good airtightness, so as to solve the technical problems mentioned in the above background technology.

[0006] An aluminum alloy door and window with good airtightness comprises a window frame and a window sash, wherein the window sash is hinged on one side of the window frame, and the left and right side walls and the upper and lower side walls of the window sash are fixedly connected with sealing air bags, a sealing component is arranged on the side of the window sash close to the window frame, and a corrugated groove is formed inwardly on the side of the window frame close to the sealing component.

[0007] Furthermore, the sealing assembly includes a sealing strip and a pressure groove. A pressure groove is opened on one side of the window frame, a sealing strip is slidably arranged in the pressure groove, an airway is arranged on one side of the pressure groove, and the side of the airway away from the pressure groove is connected to the sealing airbag.

[0008] Furthermore, a side of the sealing strip close to the pressure groove is raised to form an elastic portion, and a cross section of the elastic portion is larger than an opening cross section of the pressure groove.

[0009] Furthermore, at least two circular grooves are equidistantly spaced apart on a side of the sealing strip close to the pressure groove, a positioning column is slidably connected in the circular groove, and a side of the positioning column away from the sealing strip is fixedly connected to the pressure groove.

[0010] Furthermore, a gap for squeezing the sealing airbag is reserved between the window frame and the window sash.

[0011] Furthermore, the corrugated grooves are composed of transverse grooves and vertical grooves, wherein the transverse grooves are arranged on the upper and lower sides of the inner wall of the window frame, and the vertical grooves are arranged on the left and right sides of the inner wall of the window frame, and the transverse grooves and the vertical grooves are arranged in multiple groups in sequence from the inside to the outside.

[0012] In summary, the present invention includes at least one of the following beneficial technical effects:

[0013] 1. The aluminum alloy door and window with good air tightness can provide multiple seals when the window sash and the window frame are closed by means of the provided sealing airbag and the sealing component, completely blocking the flow of air, effectively improving the sealing effect of the aluminum alloy window and enhancing the air tightness of the aluminum alloy window. The sealing component is triggered when the sealing airbag is squeezed, which can reduce the damage in the sealing cavity when squeezed, effectively delay the aging speed of the sealing airbag, and improve the service life of the aluminum alloy window;

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Example:

[0023] Reference Figure 1 - Figure 4 The utility model discloses an aluminum alloy door and window with good airtightness, comprising a window frame 1 and a window sash 2, wherein the window frame 1 is hinged with the window sash 2 on one side, and the left and right side walls and the upper and lower side walls of the window sash 2 are fixedly connected with sealing airbags 3, and a sealing component 4 is arranged on the side of the window sash 2 close to the window frame 1, and a corrugated groove 5 is formed on the side of the window frame 1 close to the sealing component 4.

[0024] In this embodiment, when closing the window, the window sash 2 gradually contacts the window frame 1, and then the side of the window frame 1 squeezes the sealing airbag 3 on the side of the window sash 2. The sealing airbag 3 is squeezed to reduce the gap between the window sash 2 and the window frame 1, thereby playing a sealing role and improving the airtightness of the aluminum alloy window.

[0025] When the sealing airbag 3 is squeezed, the gas in the sealing airbag 3 will enter the sealing component 4 along the airway 7, and then the sealing strip 41 in the sealing component 4 will be pushed out by the air, so that the sealing strip 41 will contact the corrugated groove 5 of the window frame 1, thereby performing a second sealing, which can further improve the sealing effect of the aluminum alloy window.

[0026] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the sealing assembly 4 includes a sealing strip 41 and a pressure groove 42. A pressure groove 42 is opened on one side of the window frame 1. The sealing strip 41 is slidably arranged in the pressure groove 42. An airway 7 is arranged on one side of the pressure groove 42. The side of the airway 7 away from the pressure groove 42 is connected to the sealing airbag 3.

[0027] In the present embodiment, because the sealing airbag 3 is used to provide sealing when the window sash 2 is combined with the window frame 1, and when the sealing airbag 3 is squeezed, its inner wall will be stretched due to deformation, so that the material is aged faster during frequent stretching and contraction, which will affect the sealing of the sealing airbag 3. Therefore, an airway 7 is provided, and the sealing airbag 3 is connected to the pressure groove 42 by the airway, so that when the sealing airbag 3 is squeezed, the air enters the pressure groove 42 along the airway 7, and then the air pressure in the pressure groove 42 increases to push the sealing strip 41 out, so that the sealing strip 41 contacts the window frame 1, which slows down the aging speed of the sealing airbag 3 while providing the aluminum alloy window with an additional seal, thereby further improving the airtightness of the aluminum alloy window.

[0028] In a further preferred embodiment of the present invention, Figure 3 As shown, a side of the sealing strip 41 close to the pressure groove 42 is raised to form an elastic portion 6 , and the cross section of the elastic portion 6 is larger than the opening cross section of the pressure groove 42 .

[0029] In this embodiment, the elastic part 6 can be used to contact and squeeze the inner wall of the pressure groove 42 to reduce the gap between the sealing strip 41 and the pressure groove 42, thereby preventing air leakage in the sealed airbag 3 and ensuring the stability of the sealing effect. The provision of the elastic part 6 can also prevent the sealing strip 41 from slipping out of the pressure groove 42, making the use of the sealing assembly 4 more stable.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, at least two circular grooves 8 are equidistantly spaced apart on one side of the sealing strip 41 close to the pressure groove 42 , and a positioning column 9 is slidably connected in the circular groove 8 . The positioning column 9 is fixedly connected to the pressure groove 42 on the side away from the sealing strip 41 .

[0031] In the present embodiment, since the sealing strip 41 is relatively long and is soft, a positioning column 9 is provided in the pressure groove 42 to enable the sealing strip 41 to move synchronously in the pressure groove 42. The positioning column 9 is utilized to assist the movement of the sealing strip 41, thereby ensuring that the sealing strip 41 can pop out synchronously when pushed by the air, and that the pressure at each point when the sealing strip 41 contacts the window frame 1 is the same, thereby further ensuring the stability of the sealing effect.

[0032] In a further preferred embodiment of the present invention, Figure 3 As shown, a gap for squeezing the sealing airbag 3 is reserved between the window frame 1 and the window sash 2 .

[0033] In this embodiment, because the sealing airbag 3 provides sealing between the window frame 1 and the window sash 2, the window frame 1 and the window sash 2 do not need to fit too tightly, so a gap is reserved between the window frame 1 and the window sash 2, which can make it easier to close the window frame 1 and the window sash 2. At the same time, because there is a sealing airbag 3 between the window frame 1 and the window sash 2, and the sealing airbag 3 has a thickness, in order to avoid the difficulty of closing the window sash 2 and the window frame 1, the gap reserved between the window frame 1 and the window sash 2 should be greater than the thickness of the sealing airbag 3, which can prevent the sealing airbag 3 from being damaged by excessive squeezing and affecting the sealing effect, and in order to avoid the inability to effectively squeeze the sealing airbag 3 to achieve a sealing effect when the window frame 1 and the window sash 2 are closed, the distance of the gap should be controlled to be half the height of the sealing airbag 3.

[0034] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the corrugated groove 5 consists of a transverse groove 51 and a vertical groove 52, wherein the transverse groove 51 is arranged on the upper and lower sides of the inner wall of the window frame 1, and the vertical groove 52 is arranged on the left and right sides of the inner wall of the window frame 1, and multiple groups of the transverse grooves 51 and the vertical grooves 52 are arranged in sequence from the inside to the outside.

[0035] In this embodiment, by providing the corrugated groove 5, when the sealing strip 41 is pushed by air pressure to contact the window frame 1, the outer wall of the sealing strip 41 is pressed into the corrugated groove 5, so that multiple seals can be formed when the sealing strip 41 contacts the window frame 1, which can effectively prevent the flow of air and make the airtightness of the aluminum alloy doors and windows better.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
