[0001] The invention relates to the field of doors and windows, and in particular to an environmentally friendly noise-reducing aluminum alloy noise-reducing door and window. Background Art

[0002] Environmentally friendly noise reduction aluminum alloy noise reduction doors and windows are a kind of doors and windows that combine environmental protection and noise reduction functions. They use the sound insulation technology of double-layer laminated glass materials. These glass structures can effectively reduce the propagation of sound waves and reduce the penetration of noise. In addition, the aluminum alloy material itself has good durability and recyclability, which conforms to the concept of environmental protection and is widely used in various buildings.

[0003] The Chinese patent with publication number "202410217409.2" discloses "a soundproof aluminum alloy door and window, comprising an outer frame, wherein two slide grooves are adjacently arranged in the outer frame, and a No. 1 door and window and a No. 2 door and window are respectively slidably connected in the two slide grooves, and the frames of the No. 1 door and window and the No. 2 door and window are both provided with groove cavities". Although it can play the role of "effectively improving the sound insulation effect of the entire soundproof aluminum alloy door and window, ensuring the sealing effect and service life of the rubber card seat, further ensuring the sound insulation effect of the No. 1 door and window and the No. 2 door and window, improving the sound insulation effect of the No. 1 door and window and the No. 2 door and window, and ensuring the sealing sound insulation effect between the No. 1 door and window and the No. 2 door and window", when the aluminum alloy noise reduction door and window is used, in order to ensure the sealing sound insulation effect, the door and window are usually unidirectional. The open structure cannot be opened in multiple directions and cannot be suitable for use in different occasions. After the doors and windows are opened, they can only be placed at a separate angle, which not only blocks the space near the doors and windows, but also reduces the use effect of the doors and windows. Moreover, when the doors and windows are installed with guardrails, the guardrails are also fixedly installed on the doors and windows, and the guardrails cannot be retracted according to usage needs, resulting in obstruction of vision when the doors and windows are closed, reducing the light transmission effect. When the flip-up structure doors and windows are opened, the support rods need to be moved to position the doors and windows, and the doors and windows cannot be positioned quickly, resulting in troublesome operation of opening the doors and windows. At the same time, the sunshades of the doors and windows can only be used at fixed angles, and sunshades cannot be performed after the doors and windows are opened, which brings inconvenience to the different sunshade uses of the doors and windows.

[0046] When the window frame 2 is flipped downward, the multiple guardrail rods 25 are first stacked and placed at the bottom of the guardrail installation groove 21. The rotation of the rotating link 7 will pull the pulling rope 23 out of the door and window fixing frame 1. After the pulling rope 23 is pulled out, it will drive the multiple guardrail rods 25 to rise around the guardrail installation groove 21. At the same time, the positioning ring 24 is pressed against the top of the guardrail installation groove 21 for positioning. Therefore, after the window frame 2 is flipped downward and opened, the guardrail rods 25 are simultaneously unfolded on the inner side of the door and window fixing frame 1 for protection. When the window frame 2 and the rotating link 7 are rotated and closed, the reel 26 drives the pulling rope 23 to be retracted into the door and window fixing frame 1 through the contraction of the torsion spring.

[0047] When the window sash frame 2 is flipped upward and opened, when the window sash frame 2 is parallel, the docking shaft 11 moving to one side is snapped into the positioning buckle 13, thereby achieving the effect of positioning the window sash frame 2, so that the window sash frame 2 remains in a parallel opening state after being flipped upward and opened;

[0048] When the window frame 2 is closed and flipped upward to open, the winding rod 14 can be rotated around the two positioning buckles 13 to pull the curtain end rod 16 to release the sunshade curtain 15 from the outside of the winding rod 14, so that the sunshade curtain 15 covers the front of the soundproof glass 5, and then the curtain end rod 16 is connected to the positioning groove on the magnetic door handle 20 by magnetic attraction to position the sunshade curtain 15, so that it has a sunshade effect when the window frame 2 is closed and flipped upward to open.
