Further: the rotating shaft A and the rotating shaft B correspond to the positions of the positioning steel ball assemblies, and steel ball positioning holes are formed in the outer circle of the shaft to limit the angular positions of the positioning door leaf hinge plate and the rotating arm, the rotating shaft A and the rotating shaft B.
Compared with the combination of the plane gasket A and the plane gasket B with the end face of the T-shaped shaft sleeve, the bearing capacity and the service life of the steel ball plane bearing are stronger and longer.
In sum, the double-shaft rotating arm hinge has the advantage that the door leaf is convenient to mount and dismount. The combination of the gasket and the shaft hole sleeve enables the rotating arm hinge to rotate easily and flexibly during loading, plays a role of a plane bearing, and has stronger bearing capacity and longer service life compared with a steel ball plane bearing. In addition, the two ends of the rotating shaft of the rotating arm assembly are fixedly connected with the end face shaft holes of the door frame mounting seat or the door frame hinge plate into a whole by riveting or welding, so that the bearing capacity of the door frame mounting seat or the door frame hinge plate is enhanced, and the rotating arm hinge is prevented from sagging under stress. Due to the double-shaft structure, the opening angle of the door leaf can be 180 degrees, and the opening angle of the first shaft (rotating shaft A) of the door frame is not enough to compensate the opening angle through the second shaft (rotating shaft B) of the door leaf edge.
