Description

Technical Field

[0001] The invention relates to the technical field of window sash hinges, and in particular to a movable window sash hinge structure. Background Art

[0002] The window sash hinge is used to connect the window sash and the window body to realize the flipping movement of the window. The patent with application number 202011457529.8 discloses a window sash hinge, including a bottom groove piece installed on the European standard frame groove, the bottom groove piece is provided with a through hole, and the edge of the through hole is extended with a card slot, the card slot and the European standard frame groove are in contact, and the card slot is provided with a fastening hole for fixing, so that the bottom groove piece and the European standard frame groove are fastened. The bottom groove piece is quickly positioned on the European standard frame groove through the card slot. The width of the third connecting rod matches the European standard C groove, and the third connecting rod can be directly inserted into the European standard C groove. The third connecting rod and the window sash are connected in the horizontal direction, which effectively improves the assembly efficiency.
