[0045] As for the male tenon 505 and the female groove 506, the horizontal cross-sections of the male tenon 505 and the female groove 506 are both rectangular, so that the male tenon 505 and the female groove 506 have a good positioning guide design during the sliding cooperation, thereby ensuring that the plate-shaped sound insulation screen body 2 and the arc-shaped sound insulation screen body 1 can be accurately limited and assembled together. The female grooves 506 are all blind grooves in the vertical direction and are opened from top to bottom, and the bottom surface of the arc-shaped sound insulation screen body 1 is in contact with the top surface of the plate-shaped sound insulation screen body 2.
