Abstract
The invention discloses a hinge device. Through the arrangement of a first cam and a second cam which are mutually matched and can rotate relatively; the rotation of a rotary shaft enables a third protrusion on the second cam to rotate in a first groove of the first cam; when the third protrusion rotates and is blocked by the second protrusion, fixed self-locking is formed; when external force is applied continuously to enable the rotary shaft to rotate, the third protrusion slides through the second protrusion, is inserted into the second groove in a matching mode and is fixed under the angle; when external force is continuously applied to the rotary shaft to rotate, the third protrusion slides through the first protrusion at the other side and enters the first groove at the other side; and the first protrusion blocks the third protrusion, thus fixed self-locking is realized for the rotary shaft. The hinge device is applied between a screen and an enclosure which need to be connected in a rotation mode, thus the enclosure is arranged above, and the screen is arranged below; the screen can automatically rotate relatively to the enclosure for certain angle after starting up and can rotate under multiple angles for fixed self-locking; and the hinge device is simple in structure, is convenient to use, and has high practical applicability.
