Hinge structure
First Claim
1. A hinge structure, comprising:
- a pivot shaft being provided at a first end with a mounting section for connecting to a mainframe of a clam-type electronic apparatus, and at a second end with a shaft section having a tightening section provided at a free end thereof;
a bracket that is an L-shaped member having a first arm serving as a mounting arm for connecting to a screen of said clam-type electronic apparatus, and a second arm normal to said first arm;
said second arm being provided at a predetermined position with a shaft hole for rotatably engaging with said shaft section of said pivot shaft;
a fastening member; and
at least one internally toothed clamp ring located between said bracket and said fastening member, and provided along an inner circumferential edge with a plurality of radially inward projected teeth;
said bracket and said at least one internally toothed clamp ring being sequentially mounted on said pivot shaft and said fastening member being screwed to said tightening section at the second end of said pivot shaft to form said hinge structure;
said mounting section of said pivot shaft and said mounting arm of said bracket being connected to said mainframe and said screen, respectively, of said clam-type electronic apparatus;
said teeth of said at least one internally toothed clamp ring being adapted to firmly engage with and grip at an outer surface of said shaft section of said pivot shaft, and thereby preventing said fastening member from turning along with said screen when said screen is pivotally turned, ensuring said fastening member is not separated from said pivot shaft after said screen has been pivotally turned many times.

Abstract
A hinge structure includes a pivot shaft, a bracket, a fastening member, and at least one internally toothed clamp ring located between the pivot shaft and the bracket. The bracket and the clamp rings are sequentially mounted on the pivot shaft and the fastening member is screwed to a tightening section at an end of the pivot shaft. The pivot shaft and a mounting arm on the bracket are separately connected to a mainframe and a screen of a clam-type electronic apparatus, such as a notebook computer. The teeth of the clamp rings would firmly engage with and grip at an outer surface of the pivot shaft to prevent the fastening member from turning along with the screen when the latter is pivotally turned relative to the mainframe. Therefore the fastening member would not separate from the pivot shaft after the screen has been pivotally turned many times.
