1. Field of the Invention
The present invention relates to a hinge, and more particularly to a hinge that can rotate from 0 degree to 360 degree or even more degree to achieve location function.
2. The Related Art
Hinges are widely used to link various electronic parts together such as mobile phone, video camera and so on. A hinge for circumrotatory location is shown in FIG. 9. The hinge for circumrotatory location 700 includes a cover with a top cover 77 and a bottom cover 72, a pivot 71, a plastic ring 73, a stop means 74, a steel ball 75, a turnplate 76 and a latch 78. The stop means 74 includes a chassis 741, a stop tray 742 projecting upward from the stop tray 742 and a stop block 743 extending horizontally and outward from the stop tray 742 with a radian γ. A slide track 744 is formed around the stop tray 742 and connects with the chassis 741 with two ends connecting with the stop block 743. The turnplate 76 is fitted on the stop means 74 with an abutting block 761 formed on an exterior circle thereof. When the turnplate 76 rotates about an axis of the stop means 74, the abutting block 761 is sliding around the slide track 744 until the abutting block 761 abuts against the stop block 743. In the cooperation between the stop means 74 and the turnplate 76, the hinge for circumrotatory location 700 can rotate in a proper range to achieve location function. Meanwhile, the hinge for circumrotatory location 700 can rotate various degrees by replacing the turnplate 76 of various central angle β. Please refer to FIG. 10, with the cooperation of a first turnplate 762 and the second turnplate 763, the hinge for circumrotatory location 700 can rotate in an angle of 0˜360 degrees.
However, the hinge for circumrotatory location 700 has so many components that the structure is complex to ensure the hinge for circumrotatory location 700 working effectively. So, it would be desirable to provide a new hinge that is of simple design and low cost.
