[0026] The utility model will be made further detailed explanation in combination with the specific embodiments of the description and the drawings.

[0027] Referring to the drawings Figure 1 and the drawings Figure 4 It is shown that the embodiment provides an aluminum profile door and window sealing structure 10, which comprises an outer aluminum alloy door and window profile 103, an intermediate aluminum alloy door and window profile 102 and an inner aluminum alloy door and window profile 101, the intermediate aluminum alloy door and window profile 102 is arranged between the outer aluminum alloy door and window profile 103 and the inner aluminum alloy door and window profile 101, wherein the inner aluminum alloy door and window profile 101 is adjacent to the side of installing glass, and the outer aluminum alloy door and window profile 103 is the other side away from installing glass.

[0028] Referring to the drawings Figure 1 and the drawings Figure 4 It is shown that in the embodiment, the outer side of the intermediate aluminum alloy door and window profile 102 is respectively provided with a first Ω-shaped hollow rubber strip 200 at the engaging point of the outer aluminum alloy door and window profile 103 and the inner aluminum alloy door and window profile 101, that is, the first Ω-shaped hollow rubber strip 200 is installed on the side adjacent to the external environment of the aluminum alloy door and window profile, for example, the outdoor side.The engaging point of the inner side of the inner aluminum alloy door and window profile 101 and the intermediate aluminum alloy door and window profile 102 is provided with a second Ω-shaped hollow rubber strip 300, the memory sponge strip 500 is arranged between the inner aluminum alloy door and window profile 101 and the intermediate aluminum alloy door and window profile 102, and the sealing strip 400 is arranged between the intermediate aluminum alloy door and window profile 102 and the outer aluminum alloy door and window profile 103.In the embodiment, the structure of the first Ω-shaped hollow rubber strip 200 and the second Ω-shaped hollow rubber strip 300 is same.

[0029] When external wind acts on the aluminum alloy door and window profile, the first Ω-shaped hollow rubber strip 200 and the second Ω-shaped hollow rubber strip 300 can be self-adapting deformation to fill the gap by using the air pressure difference, so as to ensure the sealing and sound insulation effect. Specifically, when external wind acts on the aluminum alloy door and window profile, the first Ω-shaped hollow rubber strip 200 located on the outside is subjected to the maximum wind pressure, at this time, the first Ω-shaped hollow rubber strip 200 is subjected to the maximum extrusion, and the deformation of the first Ω-shaped hollow rubber strip 200 is the largest, so that the first Ω-shaped hollow rubber strip 200 is tightly pressed and closely combined at the clamping point of the outer aluminum alloy door and window profile 103 and the inner aluminum alloy door and window profile 101 on the outside of the middle aluminum alloy door and window profile 102; while the second Ω-shaped hollow rubber strip 300 located on the inside is subjected to reduced wind pressure, and the deformation amount is also relatively small. By adding multiple self-adapting sealing layers (the first Ω-shaped hollow rubber strip 200 and the second Ω-shaped hollow rubber strip 300) on the frame and fan matching surface of the aluminum profile door and window, a gradient air pressure buffer zone is formed, and the elastic material (the first Ω-shaped hollow rubber strip 200 and the second Ω-shaped hollow rubber strip 300) and the geometric structure (the clamping point between the middle aluminum alloy door and window profile 102, the outer aluminum alloy door and window profile 103 and the inner aluminum alloy door and window profile 101) are combined to break through the limitation of traditional single-point sealing. At the same time, the memory sponge strip 500 is arranged between the inner aluminum alloy door and window profile 101 and the middle aluminum alloy door and window profile 102, and the sealing strip 400 is arranged between the middle aluminum alloy door and window profile 102 and the outer aluminum alloy door and window profile 103, the memory sponge strip 500 and the sealing strip 400 are embedded in the profile joint, which compensates for the processing and assembly tolerance, ensures the sealing of the aluminum alloy door and window profile, and is beneficial to the sound insulation and waterproof and windproof effect of the aluminum alloy door and window profile.

[0030] Referring to the accompanying drawings Figure 2 shown, the accompanying drawings Figure 2 is a planar structure schematic view of the aluminum profile door and window sealing structure installed in the embodiment of the application. In the embodiment, in order to achieve better noise reduction effect, the inner aluminum alloy door and window profile 101 is provided with a plurality of cavities 600 arranged from outside to inside, and the plurality of cavities 600 are arranged to make the external noise gradually decrease when the noise passes through the aluminum profile door and window into the indoor.

[0031] Referring to the accompanying drawings Figure 1 , the accompanying drawings Figure 3 and the accompanying drawings Figure 4As shown, the first clamping groove is arranged at the clamping point of the outer side of the outer aluminum alloy door and window profile 103 and the inner aluminum alloy door and window profile 101, and one end of the first omega-shaped hollow rubber strip 200 is clamped and installed in the first clamping groove. The arrangement of the first clamping groove makes the first omega-shaped hollow rubber strip 200 not easy to fall off, and ensures the sealing performance at the clamping point between the outer aluminum alloy door and window profile 103, the inner aluminum alloy door and window profile 101 and the intermediate aluminum alloy door and window profile 102.

[0032] Referring to the accompanying drawings Figure 3 As shown, specifically, the first omega-shaped hollow rubber strip 200 includes a rubber strip body 201 with a circular cross section and a first limiting portion 202. A through hole 205 is arranged at the center of the rubber strip body 201, and the first limiting portion 202 is arranged at the other end of the rubber strip body 201. The first limiting portion 202 is a limiting rubber strip arranged horizontally, and is connected with the rubber strip body 201 through a rubber strip connecting portion 204. A second limiting portion 203 extending horizontally to the left and right sides by a distance is arranged at one end of the rubber strip body 201 close to the first limiting portion 202. The outer dimension of the rubber strip connecting portion 204 is smaller than the slot opening dimension of the first clamping groove, and the outer dimensions of the first limiting portion 202 and the second limiting portion 203 are greater than the slot opening dimension of the first clamping groove.

[0033] When the first omega-shaped hollow rubber strip 200 is installed in the first clamping groove, the first limiting portion 202 is clamped into the first clamping groove, and the rubber strip connecting portion 204 is installed in the slot of the first clamping groove. Since the outer dimensions of the first limiting portion 202 and the second limiting portion 203 are both greater than the slot opening dimension of the first clamping groove, when the first omega-shaped hollow rubber strip 200 is deformed under pressure, the slot of the first clamping groove is limited in the front and back directions by the first limiting portion 202 and the second limiting portion 203 respectively. Therefore, the first omega-shaped hollow rubber strip 200 is difficult to separate from the first clamping groove, and the sealing performance of the first omega-shaped hollow rubber strip 200 at the clamping point is ensured.

[0034] Referring to the accompanying drawings Figure 1 to the accompanying drawings Figure 3 As shown, it should be noted that the installation structure of the second omega-shaped hollow rubber strip 300 installed at the clamping point of the inner side of the inner aluminum alloy door and window profile 101 and the intermediate aluminum alloy door and window profile 102 is the same as that of the first omega-shaped hollow rubber strip 200, and will not be described here.

[0035] In some embodiments, the first omega-shaped hollow rubber strip 200 and the second omega-shaped hollow rubber strip 300 are made of EPDM sealing strips.
