Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a left-right adjustable hinge. Background Technology

[0002] Spool-type (grooveless) hinges consist of several connecting rods. Their key feature is that all hinge points are hinged to each other via a central axis. Their biggest advantage is extremely quiet operation, making them popular among users. Most spool-type hinges on the market, especially those with left / right adjustment mechanisms on the window frame connecting piece, automatically change the distance (hole spacing) at a certain pivot point (the hinge point between two connecting rods) when adjusting the hinge's left / right or inward / outward position. Spool-type hinges are very sensitive to hole spacing. If the hole spacing changes, the hinge structure may bulge outward or recede inward when the window is closed, leading to problems with window sealing (too tight or too loose) and other instability, affecting the user experience.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a left-right adjustable hinge that is simple in structure, has good sealing performance, is stable and reliable, provides a good user experience, and is highly practical, so as to overcome the shortcomings of the prior art.
