Abstract

The invention discloses a large-angle opening and closing blind hinge which comprises a hinge arm, two ends of the hinge arm are a frame hinge end and a sash hinge end respectively, and the frame hinge end is hinged to a frame hinge piece and has a shape suitable for being retracted into and extended out of a space in a frame. The sash hinge end is hinged with the sash hinge piece and has a shape suitable for being retracted into and extended out of the sash inner space; a frame clamping pair capable of keeping positioning mutually and a frame end limiting mechanism for limiting the frame hinging piece and the frame hinging end to relatively rotate at a preset angle are arranged between the frame hinging piece and the frame hinging end; a sash clamping pair capable of keeping positioning mutually and a sash end limiting mechanism for limiting the relative rotation angle of the sash hinge piece and the sash hinge end are arranged between the sash hinge piece and the sash hinge end. Due to the fact that the limiting mechanism is limited between the hinging piece and the hinging end, the door and window blind hinge capable of being opened and closed at the large angle does not need to be additionally provided with an additional structure to serve as a fixed blocking point, and manufacturing and assembling are more convenient.
