[0001] The utility model relates to the technical field related to aluminum alloy doors and windows, in particular to a sealing structure for aluminum alloy doors and windows. Background Art

[0002] As living standards improve, people's expectations for doors and windows are becoming increasingly demanding. Aluminum alloy windows, owing to their aesthetics, sealing properties, and high strength, are widely used in construction projects. In home decoration, aluminum alloy doors and windows are often used to enclose balconies. However, existing aluminum alloy doors and windows lack a tight seal, allowing external contaminants to seep into the home. Furthermore, during strong winds and heavy rain, the poor sealing of these doors and windows allows rainwater to enter the home, disrupting daily life. Utility Model Content

[0003] The utility model aims to overcome the disadvantage of poor sealing effect in the prior art and provides an aluminum alloy door and window sealing structure with good sealing effect.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an aluminum alloy door and window sealing structure, comprising a door and window outer frame and a door and window inner frame hinged to the upper end of the door and window outer frame, a sealing groove is provided on the top of the door and window outer frame, and the side outer surface and the bottom outer surface of the door and window outer frame are elastically hinged with a sealing strip, and a limited edge is provided around the door and window inner frame, and the limited edge at the top of the door and window inner frame is engaged with the sealing groove, and the limited edges at the side and bottom ends of the door and window inner frame are placed between the sealing strip and the door and window outer frame, and a pull wire assembly is installed in the sealing groove, and the pull wire assembly is matched and connected with the limiting edge, and the pull wire assembly is connected with a pull wire, and the pull wire is connected to the sealing strip.

[0005] The present door and window sealing structure includes an outer door and window frame and an inner door and window frame. The inner door and window frame is connected to the top of the inner door and window frame's inner sidewall via a hinge, enabling the inner door and window frame to be opened. A sealing groove is provided at the top of the outer door and window frame, and the inner wall of the sealing groove is provided with a sealing material such as a sealing strip. Furthermore, limiting edges are provided around the inner door and window frame. The limiting edge at the top of the inner door and window frame can be snapped into the sealing groove when the window is closed. This ensures that when the door and window are closed, the gap formed between the top of the inner door and window frame and the top of the outer door and window frame is positioned within the sealing groove, thereby ensuring a good seal. Sealing strips are provided on both sides and the bottom of the outer surface of the outer door and window frame, and are elastically hingedly connected to the outer door and window frame. A pull wire assembly is installed in the sealing slot, and a pulling wire is connected to the pull wire assembly. The pulling wire is also connected to the sealing strip. When the limiting edge inserted into the sealing slot cooperates with the pull wire assembly, the pulling wire connected to the pull wire assembly is pulled. The pulling wire can cover the sealing strip to cover the gap between the inner frame and the outer frame of the door and window when they are closed, thereby improving the sealing effect.

[0006] Preferably, a clearance groove is provided inside the sealing card slot, and an installation groove is provided on the door and window outer frame. The wire pulling assembly includes a winding shaft, a gear shaft and a push plate. The winding shaft and the gear shaft are coaxially connected and placed in the installation groove.

A pull wire assembly is installed in the sealing slot 10, and a pulling wire 4 is connected to the pulling wire assembly. The pulling wire 4 is also connected to the sealing strip 3. When the limiting edge 20 inserted into the sealing slot 10 cooperates with the pulling wire assembly, the pulling wire 4 connected to the pulling wire assembly is pulled. The pulling wire 4 can cover the sealing strip 3 with the gap between the door and window inner frame 2 and the door and window outer frame 1 when they are closed, thereby improving the sealing effect.

[0030] The yield groove 11 arranged inside the sealing card slot 10 is used for the installation of the push plate 7 in the wire pulling assembly, and the installation groove 12 arranged on the door and window outer frame 1 is used for the installation of the winding shaft 5 and the gear shaft 6 in the wire pulling assembly. At the same time, a rack 70 is installed on the side wall of the push plate 7. The rack 70 can engage with the gear shaft 6, so that the movement of the push plate 7 can drive the rotation of the gear shaft 6. At the same time, the gear shaft 6 and the winding shaft 5 are coaxially connected. The rotation of the gear shaft 6 can drive the winding shaft 5 to rotate, and then the pulling wire 4 can be wound, so that the pulling wire 4 is tightened, so that the sealing strip 3 is flipped and pressed down, so that the pulling wire 4 can cover the gap between the door and window inner frame 2 and the door and window outer frame 1 when the sealing strip 3 is closed, thereby improving the sealing effect. The buffer spring 13 provided can play a buffering role, so that the push plate 7 can slide in the give way groove 11 when the door and window are opened and closed, thereby controlling the tensioning and relaxation of the pull wire 4, ensuring that the pull wire 4 is controlled to pull the sealing strip 3 downward, thereby realizing that the sealing strip 3 covers the gap between the door and window inner frame 2 and the door and window outer frame 1 when they are closed, thereby improving the sealing effect.
