Quick roller shutter door/window with relatively small roller diameter
The invention provides a quick roller shutter door/window with a relatively small roller diameter. The quick roller shutter door/window is characterized in that the middle part of each body is of an arc-shaped plate strip type structure, the upper part of each body is provided with an arc-shaped upper hook body, the lower part of each body is provided with a pillow part, the middle of the rear side of each pillow part is of a semi-open double-hole design, the upper part of each pillow part is provided with a locking part, the lower part of each pillow part is provided with a lower hook body, each locking part is matched with a screw, the front end of each screw is provided with threads, and the rear part of each screw is provided with a guiding wheel. The upper hook body of one curtain sheet transversely penetrates into the lower hook body of another curtain sheet, the screws and the locking parts are matched with each other and sequentially penetrate into curtain sheets so as to form a door/window body, the bottoms of the pillow parts of all curtain sheets are closely overlapped sequentially when the door/window body is wound onto a rotating shaft, and each subsequent rolled curtain sheet is provided with a specific radius design which is used for accommodating a continuously-increasing roller diameter, so that the overlapped gap among the curtain sheets during the winding of the roller shutter door is almost zero through carrying out optimal combination on a curtain sheet overlapped state when the roller shutter door/window is wound, and the diameter of a roller can be minimal.
