HINGE, SLIDING ASSEMBLY AND PORTABLE DEVICE

摘要

A hinge is mounted in a sliding assembly for a portable device. The hinge has a hollow pintle, a first positioning ring, a second positioning ring and a resilient element. The positioning rings are mounted around the pintle and respectively have corresponding detents and protrusions to provide positioning function. The resilient element is mounted in the pintle and is mounted between the positioning rings to reduce the length of the hinge. When the second positioning ring is rotated, the second positioning ring also moves upward to lift the supporting panel of the sliding assembly and the cover of the portable device. Therefore, the cover is kept from bumping into the expanding parts of the portable device.
