Sound insulation mechanisms are arranged on the inner sides of the first frame and the second frame. A positioning pin is fixedly connected to one side of the first frame, and a positioning sleeve adapted to the positioning pin is fixedly connected to one side of the second frame. A pull ring is fixedly connected to the top of the plug-in strip. A first installation groove is opened on one side of the top of the first frame, and a second installation groove is opened on one side of the top of the second frame. The plug-in strip is adapted to the first installation groove and the second installation groove.

[0007] By adopting the above technical solution, good sound insulation can be achieved at the splicing position, and the use effect of the sound insulation screen can be improved.

[0008] Preferably, the sound insulation mechanism includes an aluminum perforated plate, an inorganic perforated plate and sound insulation cotton. Waterproof cloths are arranged on both sides of the sound insulation cotton. The sound insulation cotton is rock wool. The through holes opened on the aluminum perforated plate and the inorganic perforated plate are regular hexagons.

[0009] By adopting the above technical solution, a good sound insulation effect can be achieved.

[0010] Preferably, the plug-in strip is a sound-absorbing cotton board.

[0011] By adopting the above technical solution, the sound insulation effect at the splicing position is increased.

[0012] In summary, the present application has the following beneficial technical effects: By providing the insertion strips, the splicing positions of the sound insulation screens can be well sound-insulated, thereby enhancing the sound insulation effect during the use of the sound insulation screens. Additionally, by providing the waterproof cloth, the entry of dust and water vapor into the sound insulation cotton can be reduced, improving its continuous usage effect.
