Roller shutter with turnover curtain cloth

Abstract

The invention discloses a roller shutter with turnover curtain cloth, comprising a housing, a left cover plate, a right cover plate, a shutter assembly, a left guide rail, a right guide rail, a base, a rotating shaft, a manual pulling device and a one-way rotating device, wherein the rotating shaft is arranged between the left cover plate and the right cover plate and inside the housing, internally provided with a tubular motor and connected with the uppermost end of the shutter assembly; the shutter assembly comprises a blind shutter curtain, a top fixed blind and a bottom beam blind, wherein two ends of the blind shutter curtain are respectively provided with a turning chain and a fixed chain, when the turning chain moves upwards or downwards relative to the fixed chain, the turning chain drives an articulated element to rotate, the articulated element is fixedly connected with a blind slat unit, and thus, blind slats are driven to rotate. The roller shutter is simple in operation and control and convenient to use.

Description

technical field [0001] The invention belongs to the field of doors and windows, in particular to a rolling shutter with reversible curtains. Background technique [0002] Currently used in the field of building doors and windows, there are roller blinds made of alloys for heat preservation, sunscreen and sunshade, but their light transmission is not good, and ordinary venetian blinds with good light transmission have weak wind pressure resistance. In order to solve the above problems, there have been The utility model relates to a reversible venetian shutter window. When the roller blind is lowered, the louver blades can be turned over. When the roller blind is retracted, the louver blades are turned into a vertical state, and the shutter blades are closed by a reel. At present, the joints used for the connection of roller blinds are relatively complicated, and a special control device needs to be installed on the upper part of the joints, and the installation and control pr...

Problems solved by technology

[0002] Currently used in the field of building doors and windows, there are roller blinds made of alloys for heat preservation, sunscreen and sunshade, but their light transmission is not good, and ordinary venetian blinds with good light transmission have weak wind pressure resistance. In order to solve the above problems, there have been A venetian shutter window with reversible curtains. When the roller blind is lowered, the louver blades can be turned over. When the roller blind is retracted, the louver blades are turned into a vertical state, and the shutter is closed by the reel.

At present, the joints used for the connection of roller blinds are relatively complicated, and special control devices need to be installed on the upper part of the joints, and the installation and control processes are relatively complicated.
