Abstract

The convenient curtain of the present invention, the lower end of the curtain is connected with a bottom box, the bottom box is hollow inside, and a screw rod is arranged in it; two nuts are threaded on the screw rod, one of which is located on one side of the curtain, and the nut and the wire The rods are left-hand threaded, the other is located on the other side of the screen, and the other pull ring extends out of the displacement groove and is connected to the other side of the screen through a pull wire. When water ripples or V-shaped patterns appear on the screen, turn and adjust the screw rod so that the two wire nuts drive the pull ring to move away from each other, and the pull ring will apply tension to both sides of the screen through the pull wire, thereby flattening the screen. Tight, fast and convenient to eliminate water ripples or V-shaped lines, adjust the flatness of the screen, and improve the viewing effect.
