At this time, the connection between the window door 3 and the window frame 1 is filled with the sealing strip 18 and the sealing strip 20, so that the gap between the window door 3 and the window frame 1 is sealed to prevent noise from entering. The double-layer glass 19 is fixed to the inner wall of the window door 3 and is filled with inert gas. In combination with the sealing strip 18 and the sealing strip 20, the sealing effect of the device is further enhanced.

[0048] Moreover, when the noise outside the window is loud, the sound insulation cloth 205 is pulled downward to release the sound insulation cloth 205 wrapped around its outer wall by the rotating shaft 202, and then the multiple hooks 206 connected to the bottom of the sound insulation cloth 205 are hung in the circular hole 21 opened at the bottom of the window frame 1 to unfold and fix the sound insulation cloth 205. When the sound insulation cloth 205 needs to be collected, the hooks 206 are disengaged from the circular hole 21, and then the torsion springs 203 fixed on both sides of the rotating shaft 202 release the rotational force on the rotating shaft 202, so that the extended sound insulation cloth 205 passes through the retractable groove 22 and is rewound onto the outer wall of the rotating shaft 202, completing the storage of the sound insulation cloth 205. While not affecting the normal lighting effect, part of the noise is isolated.
