Abstract: A hinge has a mounting bracket, a hinge assembly, a limit and positioning element, a bushing assembly, a supplementary positioning element and an end cap. The mounting bracket has two limits and a mounting hole. The hinge assembly is mounted rotatably through the mounting hole of the mounting bracket and has at least one pintle and at least on leaf mounted pivotally on the pintle. The limit and positioning element is mounted securely around the mounting cylinder and slidably against the mounting bracket and keeps the hinge assembly from over-rotating. The bushing assembly comprises at least one plastic washer, is mounted securely around the mounting cylinder and slidably abuts the mounting hole in the mounting bracket. The supplementary positioning element is mounted around the mounting cylinder and slidably against the mounting bracket. The end cap attaches to the mounting cylinder to hold the hinge assembly on the mounting bracket.
