Abstract
A positioning hinge has a body, a pivotal shaft, a securing base and an automatic closing device. The pivotal shaft is mounted in the body and has at least one positioning face defined in the pivotal shaft. The securing base is connected pivotally to the body with the pivotal shaft. The automatic closing device is connected to the pivotal shaft and has at least one cylinder provided with pressured air. The at least one cylinder connects to and pushes the at least one positioning face on the pivotal shaft to provide an automatic closing force to the door panel with the pressured air when the pressured air in the at least one cylinder is compressed. Accordingly, the positioning hinge can automatically close a door panel slowly and smoothly with the pneumatic pressures provided by the cylinders.
