Embodiment
Please refer to Fig. 1, first of the utility model pivot device is executed mode and is comprised a fixed block 10, a rotating shaft 20 and a revolving part 30.
Fixed block 10 comprises that a junction 12 and is positioned at the columned fixing part 14 of a side of joint 12.Joint 12 is provided with some fastener holes 120, passes for screw or rivet, thereby fixed block 10 is fixed in the base of flip cover assembly, as the main body (figure does not show) of notebook computer.Fixing part 14 is axially arranged with a fixed hole 142 that is two " D " shapes.
Revolving part 30 comprises that a locking part 32 and is by the curling shaft sleeve part 34 that forms of a side of locking part 32.Locking part 32 is provided with some fastener holes 320, passes for screw or rivet, thereby revolving part 30 is fixed in the loam cake of flip cover assembly, as the screen (figure does not show) of notebook computer.
Please in conjunction with reference Fig. 2, during assembling, the fixed end 22 of rotating shaft 20 is fixed in the fixed hole 142 of fixed block 10, so that fixed block 10 is fixed in rotating shaft 20.The axostylus axostyle 24 of rotating shaft 20 inserts the shaft sleeve part 34 of revolving part 30, and revolving part 30 can be rotated around axostylus axostyle 24.Bizet 26 backstops of rotating shaft 20 are in the wherein end face of a sleeve 344 of shaft sleeve part 34.The plane 242 of rotating shaft 20 is over against the inwall of a sleeve 344 wherein.
During use, revolving part 30 rotates around axostylus axostyle 24, and the inwall of sleeve 344 rotates along the periphery of axostylus axostyle 24.When the plane 242 of axostylus axostyle 24 relatively rotated to opening 346 over against sleeve 344, it is maximum that the frictional force between sleeve 344 and the axostylus axostyle 24 reaches.Be rotated further revolving part 30, relatively rotate to once more in the process of the inwall of sleeve 344 up to plane 242, the frictional force between sleeve 344 and the axostylus axostyle 24 reduces gradually.
Please refer to Fig. 3, second of the utility model pivot device is executed mode and is comprised a fixed block 10a, a rotating shaft 20a and a revolving part 30a.
Fixed block 10a comprises that a junction 12a and is positioned at the columned fixing part 14a of the side of joint 12a.Joint 12a is provided with some fastener hole 120a, passes for screw or rivet, thereby fixed block 10a is fixed in the base of flip cover assembly, as the main body (figure does not show) of notebook computer.Fixing part 14a is axially arranged with a fixed hole 142a who is two " D " shapes.
