Abstract
Disclosed is a computer rotary shaft positioning mechanism with torsion strengthened. The computer rotary shaft positioning mechanism comprises a movable support, a fixed support and a mandrel. The movable support is connected with a liquid crystal display panel. The fixed support is connected with a computer base. One end of the mandrel is fixed onto the fixed support, and the other end of the mandrel is rotatably fixed onto the movable support. The mandrel penetrates the movable support, a concave wheel and a cam to screw a nut. A positioning protrusion and a positioning hole are correspondingly formed in the concave wheel and the movable support respectively and are convenient to fix relatively. The cam is radially provided with a large-end protrusion and a small-end protrusion which are arranged on an outer circular surface and an inner circular surface of the cam respectively. The concave wheel is radially provided with a large-end recess and a small-end recess which are formed in an outer circular surface and an inner circular surface of the concave wheel, respectively. In the case that the liquid crystal display panel is closed, the large-end protrusion and the small-end protrusion slide in the large-end recess and the small-end recess, respectively. An outer arc protrusion and an inner arc protrusion are formed along the outer circular surface and the inner circular surface of the concave wheel, respectively and are in the slope forms. As the liquid crystal display panel rotates to a touch screen, the large-end and the small-end protrusions are slidably supported on the outer and the inner arc protrusions, respectively. By the use of the computer rotary shaft positioning mechanism, the screen never leans back when the touch function is in service.
