Abstract
A self-lock hinge is mounted between a cover and a base of an electronic device and has a resilient sleeve and a pintle. The resilient sleeve has a tubular body with a positioning protrusion formed on an inside wall thereof. The pintle has a rod. The rod is mounted rotatably through the tubular body and has a flat wall selectively abutting the positioning protrusion. When the cover is closed relative to the base, the flat wall of the rod abuts the positioning protrusion to lock the cover. Therefore, the cover is self-locked when closing.
