<p>A wind-up screen device, includes a bracket (1) to which a rotation driven mechanism (3) is fixed on one end of the bracket. The blind (7) can rotate under the action of the rotation driven mechanism (3) through the blind reel (4A), or the curtain or the shutter (7) can rotate under the action of the rotate drive mechanism (3) through the cord reel (4), an elasticity traversing mechanism (14) and a traversing release device (5) are also connected to the rotate drive mechanism (3). The rotation driven mechanism (3) is made up of a cord turn plate (3c), a clutch (6) that connected with the cord turn plate, and a recuperation spring (3c) which is placed between the cord turn plate (3c) and the cord turn plate box (3a). Thus only a single cord can control the blind and the gyroidal movement of the blind reel won't affected by the rotation driven mechanism (3), which made it convenient to use and will not cause injury to children.</p> |
