In this embodiment, the flexible clamping portion 20 is a flexible adhesive tape. The flexible adhesive tape is fixedly connected to the lower edge of the curtain body 2. The thickness of the flexible adhesive tape is larger than that of the curtain body 2, and the flexible adhesive tape can be limited and connected in the horizontal limiting groove 40 of the lower beam 4, so that the lower end of the curtain body 2 is fixed with the lower beam, and the curtain body 2 sags and tightens to play a role in wind prevention and light shielding.
Further, a light shielding plate 32 is provided on the outer side surface of the side pillar 3, and the light shielding plate 32 protrudes in the horizontal direction to cover the gap between the curtain body 2 and the guide rail 31. The light shielding baffle 32 can play a role in shielding light to prevent light from radiating in from a gap between the curtain body 2 and the guide rail 31, and can play a certain role in preventing wind to prevent the wind from directly blowing the edge of the curtain body 2 to generate noise; when the curtain body 2 is blown by strong wind, the curtain body 2 has a space capable of moving inwards and is not clamped, and when the wind power is reduced, the curtain body 2 can quickly recover the original shape under the gravity action of the lower beam 4, so that the windproof effect is achieved.
As shown in fig. 3 to 5, the lower beam 4 includes a plastic section 41 and a metal wrapping 42; the middle part of the plastic section 41 is provided with a partition plate, a horizontal limit groove 40 is formed above the partition plate and is in limit connection with the flexible clamping part 20 at the lower end of the curtain body 2, and a containing groove 43 is formed below the partition plate;
