Description

Roman curtain rolling structure

Technical Field

The utility model relates to the technical field of Roman blind roller shutters, in particular to a Roman blind roller shutter structure.

Background

The common hard curtain (such as Roman curtain and roller curtain) comprises an upper beam, a lifting unit and a curtain surface connected with the bottom of the upper beam, wherein the lifting unit is provided with a plurality of pulling ropes and lifting ropes, the curtain surface is formed by connecting a plurality of transverse drooping sections, and at least one row of through holes are arranged on the transverse drooping sections, and the lifting ropes can pass through and are fixedly connected on the through holes at the lowest part; therefore, the pulling rope can be pulled to lead the lifting rope to be linked with the curtain surface, thereby achieving the actions of ascending and descending.

However, when a general rolling shutter ascends or descends, and a pulling rope of the general rolling shutter is normally exposed at one side of a shutter surface, an infant may wind the pulling rope around a neck due to curiosity or carelessness during playing, and further, an accident such as neck tightening occurs, thereby posing a serious threat to safety of the infant.

For example, chinese patent CN201020511632.1 discloses a cordless roller shutter structure, which comprises a roller shutter body having a rod and a shutter face; a first fixed seat movably arranged at one end of the rod body; the second fixed seat is movably arranged at the other end of the rod body; and a limiting mechanism arranged between the roller shutter body and the second fixed seat and comprising an elastic unit movably arranged on the second fixed seat and a rotating shaft unit movably arranged on the second fixed seat, connected with the elastic unit and combined with the other end of the rod body. Although the structure can also realize the roller shutter structure without the pull rope, the structure has more structural components and complex structure, and is easy to damage and inconvenient to fix the position of the shutter body in the actual use process.

To this end, we propose a roman shade rolling blind structure.
