Overlap of one pair of semicircles for the folding combining structure

摘要

The invention related to an overlap of one pair of semicircles for the folding combining structure, wherein it have several yarn frame structure groups to one-way open or two-way open and one-way close or two-way close between left frame and right frame, and its characteristic lies in: Even rounds-lack overlap post consists of the left directional round-lack terminal surface plate and right directional round-lack terminal surface plate, among round-lack connected post insert in the left directional round-lack terminal surface plate and right directional round-lack terminal surface plate, and join the yarn frame structure group, so, can form several screen windows and rotate the two-way opening and closing or unilateral state that open and closing between the left frame of the window frame and right frame, in order to reach the theft-proof result of screen window.
