Description
Technical Field
The invention relates to the technical field of blind curtains, in particular to a blind curtain.
Background
Blinds can both increase the privacy of a room and present a potential hazard. For example, in a traditional manual blind, a lifting circulating pull rope with a vertical weight handle is arranged on the side surface, and the pull rope is dissociated outside a window body, so that children are easily injured accidentally. In addition, the traditional manually controlled pull rope is easy to damage the window curtain due to different force application sizes and directions of users, and the service life of the window shutter is shortened. The development and change of things are caused by contradictory motions, in order to cancel a pull rope and solve the potential safety hazard caused by the pull rope, spring roller blinds are adopted to replace the pull rope in the market at present, but all upper beams of the curtain are fixed at the top of a window, and only a lower beam can be used for lifting and controlling light. When in daily use, users often want the upper half of the window to transmit light and the lower half to shade light. For example, when getting up, a user may want to have light in a room and better privacy. The window coverings that achieve the above-described objectives or functions are collectively referred to in the industry as day and night curtains. Most of the curtains are made of two different materials, one of the two materials has good light transmission performance and the other material has good light shading performance.
