Invisible window screen with novel windproof mechanisms
An invisible window screen with novel windproof mechanisms comprises a yarn box, guide wheels, a gauze, a straining beam and a bottom border. The windproof mechanisms are arranged between two sides of the gauze and the guide rails. Each windproof mechanism comprises flexible windproof strips arranged on two sides of the gauze in a heat sealing mode and windproof throats arranged in grooves of the guide rails. Each windproof strip is composed of a heat sealing edge and continuous windproof convex strips or intermittent windproof convex blocks arranged outside the heat sealing edge. The widths of the windproof convex strips or windproof convex blocks are larger than the spaces between the windproof throats. The invisible window screen with the novel windproof mechanisms has the advantages that the heat sealing edges of the flexible windproof strips can be fixedly connected with the edge of the gauze and protect the edge of the gauze, and thus the service life of the invisible window screen is prolonged; the windproof convex strips or windproof convex blocks are integrally connected with the heat sealing edge so the windproof effect is guaranteed, the wind screen is not apt to fall, and the wind screen can move smoothly along the guide rails during use; the production process is simplified and the production efficiency is improved; the wind screen is small in space occupation after the spaced windproof convex blocks are rolled up.
