Abstract

A positioning device for a rotating shaft structure comprises a fixing member, an active member, a pivot, at least one elastic component, a screw cap, and a cam member, wherein the pivot penetrates through a first pivoting part of the fixing member and a second pivoting part of the active member, so as to enable the active member to rotate around the pivot corresponding to the fixing member; the first and second contact surface of the cam member are in conversion contact with the first pivoting part, so as to change the distance therebetween, due to the changed distance, the pivot moves to drive the screw cap to press or loosen at least one elastic component, therefore the shaft friction between the fixing member and the active member is changed to position or rotate the fixing member and the active member.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning device for a rotating shaft structure. Background technique [0002] According to the situation where people use the relative angle between two objects, it is often seen that the most common door panel in life is an example, and this kind of need has a flip, that is, it is formed by opening or covering. There are many examples of articles in operable state and non-operable state, such as portable computers, electronic dictionaries, and portable audio-visual playback devices, etc., which are well-known electronic products. [0003] In recent years, as flat panel displays, such as liquid crystal displays, LCD TVs or plasma TVs, etc., have gradually replaced traditional bulky cathode ray tubes (CRTs) due to their advantages of light weight, thinning and no radiation. ) monitor. A support assembly with a hinge structure has become an indispensable accessory for flat panel displ...
