CONCEALED HINGE WITH V-SHAPED ROTATING SHAFTS
A concealed hinge with V-shaped rotating shafts includes an upper leaf (6) and an upper support arm (4) that are hinged to a secondary hinge (1), and a lower leaf (7) and a lower support arm (5) that are hinged to a primary hinge (8). The upper leaf (6) is hinged to the lower leaf (7). The upper support arm (4) is hinged to the lower support arm (5). A hinged joint at an end of the upper leaf (6) is connected, by means of a shaft (2), to a hinged seat secured to the secondary hinge (1). A hinged joint at one end of the lower leaf (7) is connected, by means of a shaft (2), to a hinged seat secured to the primary hinge (8), and a hinged joint at the other end of the lower leaf (7) is connected to the upper leaf (6) by means of a shared shaft (3). One end of the upper support arm (4) is connected, by means of a side shaft (10), to the hinged seat secured to the secondary hinge (1), and a hinged joint at the other end of the upper support arm (4) is connected to the lower support arm (5) by means of a longitudinal shared shaft (11). A hinged joint at an end of the lower support arm (5) is connected, by means of a side shaft (10), to the hinged seat secured to the primary hinge (8). The concealed hinge is reasonable in structure design, simple and convenient to mount, safe and capable of preventing burglary, extensive in application, small in space usage and convenient to mount and transport, and has good appearance.
