Abstract
A non-pull cord blind structure includes a blind body attached to the underside of an upper beam wherein a plurality of elongated passages are equidistantly seamed from bottom to top of the blind body thereof for a support stick to be led and adapted therein respectively. A buckling piece of a fastening belt or a hook is properly attached to the bottommost elongated passage, correspondingly matched to a plurality of buckling rings equidistantly fixed to the other elongated passages thereof respectively. Thus, via the buckling piece registered with the buckling rings thereof, the blind body is levelly raised upwards and located at a desired position thereby without any pull cords applied thereto so as to ensure the safety of children in the household. Besides, the support sticks can also be withdrawn from the elongated passages of the collected blind body before the blind body is securely located by the buckling piece thereof so as to figure out various patterns at the collected slats of the blind body in display.
