Description

Technical Field

[0001] The utility model relates to the technical field of external casement hinges, in particular to an external casement hinge structure. Background Art

[0002] At present, external casement doors and windows are usually connected by external casement hinges. When opening the doors and windows, it is often necessary to control the maximum opening angle. The existing methods of limiting the opening angle of external casement hinges are mostly to add multiple hinged linkage rods to the structure that meets the opening and closing of the doors and windows, so as to achieve the requirements of large opening angle and limited angle. However, adding multiple cross-linking rods will make the structure of the external casement hinge too complicated and increase the instability. When subjected to overload thrust, the multiple hinged linkage rods will be misaligned, making the wind pressure resistance unable to meet the demand. Utility Model Content
