Pivot device capable of being rightly assembled

Abstract

The invention relates to a pivot device capable of being rightly assembled. A second latching piece is provided with a first positioning block and a second positioning block, and pivot holes of a pivot seat are provided with a first positioning groove and a second positioning groove so that a first latching piece and the second latching piece can be rightly assembled with the pivot seat to reach a right latching position and friction torque force.

Description

technical field [0001] The invention relates to a hinge device that can be correctly assembled, especially a hinge device suitable for flip-top devices, and the hinge device is provided with first and second locking parts. Background technique [0002] The known technology such as the patent No. M297612 "effort-saving cam member" in Taiwan, China, owned by the applicant of this case and announced on September 11, 2006, is formed by docking a fixed part and a sliding part, and a Shaft hole and an embedding hole, two opposite ends of the periphery of the two components form a spiral slope respectively, so that the two ends have a vertex and an adjacent low point of height difference respectively; The apexes of the apexes resist each other, and when one of the components rotates, the two apexes move from the high point to the low point along the corresponding slope of the adjacent component. [0003] However, the current clamshell electronic devices are constantly seeking inno...

Problems solved by technology

[0003] However, the structural design of clamshell electronic devices is constantly changing, and the required locking position and cam components are becoming more and more complicated. In the case of misalignment, the fixing part and the sliding part of the cam member cannot be fastened, resulting in a wrong locking position and loss of proper frictional torque. Usually, the above situation can only be checked after the assembly is completed.
