Window blind with self-tensioning inner slider

Abstract

The invention relates to the technical field of window blinds and discloses a window blind with a self-tensioning inner slider. The technical scheme is characterized in that the window blind comprisesa frame and the inner slider arranged in the frame, wherein a tensioning rope is connected to the lower part of the inner slider; a fixing seat is detachably connected in the frame and located belowthe inner slider; a tensioning bar penetrates in the fixing seat; the upper end part of the tensioning bar is fixedly connected with a fixing shaft which is sleeved with a power spring; a pulley is rotationally connected to the tensioning bar and located between the fixing seat and the power spring; the end, away from the inner slider, of the tensioning rope bypasses the pulley and is connected tothe power spring. The inner slider is tensioned by external force, so that the moving route of the inner slider is fixed, and the probability of position offset of the inner slider in the moving process is reduced.

Description

technical field [0001] The invention relates to the technical field of shutters, in particular to a self-tensioning shutter with inner sliders.

Problems solved by technology

[0004] During the use of this kind of hollow louver glass, the inner slider is moved through the cooperation of the magnetic handle. During the movement, because the movement of the magnetic handle does not have a fixed sliding track, it is extremely easy to cause the inner slider to be in the frame. The position is shifted, so that the inner slider moves upwards in an oblique shape, which increases the difficulty of moving the inner slider, resulting in laborious stretching of the blinds
