Abstract:
A window body positioning mechanism of a non pull cord window blind includes a transmission unit including two first transmission wheels meshed together, a coil spring connected between the first transmission wheels and wound round one first transmission wheel, two second transmission wheels respectively meshed with one respective first transmission wheel, and two transmission cords each having one end thereof fixedly connected to one respective second transmission wheel and being wound round the respective second transmission wheel upon its rotation, and a damper unit including a damper and a reel connected to the damper and wound round by one transmission cord in such a manner that when the blind body is being extended out or received, the damper imparts a damping resistance to the transmission cords through the reel to achieve excellent positioning effects.
