hinge

Abstract

A hinge includes a housing, a lower bracket, an upper bracket, and a stop. The housing has a locking groove. The lower bracket is hinged to the housing and is rotatable relative to the housing about a lower axis. The upper bracket is hinged to the housing and is rotatable relative to the housing about an upper axis, and is rotatably connected to the lower bracket and is rotatable relative to the housing in a synchronous and opposite manner. The stop includes a stop block, a spring arm connected to the stop block, and a latching block protruding from the spring arm on the side opposite to the stop block. The stop block limits the rotation angle of the lower bracket and the upper bracket. The latching block is detachably locked into the locking groove to secure the stop to the housing. The latching block can be operated to bend and deform the spring arm, thereby disengaging it from the locking groove.
