Blind body positioning mechanism for non pull cord window blind and window blind using same
A window body positioning mechanism of a non pull cord window blind includes two first transmission wheels, two transmission cords respectively connected with one ends thereof to the first transmission wheels, two second transmission wheels meshed together and respectively meshed with the first transmission wheels, a coil spring connecting the two second transmission wheels and selectively wound round one second transmission wheel, and two resistance units each including a one-way pawl and a resistance wheel wound by one respective transmission cord and meshed with the one-way pawl. Thus, when extending out or receiving the blind body, the friction resistance between the resistance wheels and the transmission cords and the engagement relationship between the resistance wheels and the respective one-way pawls help achieve excellent blind body positioning effects.
