Embodiment
In conjunction with Fig. 1, Fig. 2 and Fig. 3, below be further described: a kind of rotation of connecting computer liquid crystal displayer and switching mechanism, by a center roller (21,22) and rotating main body 1 form, this center roller (21,22) a relative end is individually fixed in this rotating main body 1 top, and this center roller (21,22) the other end passes respectively this swinging mounting 31 successively, the first oil sink sheet 361, recessedly take turns 32, cam 33, the second oil sink sheet 362, behind a plurality of first dish-shaped shell fragment 34 and the 3rd oil sink sheet 363, be rotated with nut 35, this swinging mounting 31 and recessed take turns 32 interfix after, activity is set in axle 22, and each axle 22 is provided with the standstill face, and this cam 33 and this first, the second and the 3rd oil sink sheet (361,362,363) be respectively equipped with corresponding restriction face, be convenient to this cam 33 and this first, the second and the 3rd oil sink sheet (361,362,363) endwisely slip respectively and radially be set in to spline axle 22, this is recessed takes turns 32 and is respectively equipped with protuberance and recess with cam 33 corresponding surfaces, be convenient to by this a plurality of first dish-shaped shell fragment 34 and nut 35, realize these swinging mounting 31 rotating position in this axle 22, thereby realize the liquid crystal screen upset location of connection.
This rotating main body 1 bottom is passed cam bit 4 successively, concave wheel piece 5, base 6, fixed friction sheet 8, behind movable friction plate 9 and the a plurality of second dish-shaped shell fragment 10, be fixed in fixed plate 7 by screw 17, this cam bit 4 is fixed in this rotating main body 1 by riveting method, and this concave wheel piece 5 is fixed in this base 6 by riveting method, and this cam bit 4 and concave wheel piece 5 corresponding surfaces are respectively equipped with boss 42 (as shown in Figure 3) and groove 51 (as shown in Figure 1), this fixed friction sheet 8 is fixed in this base 6, evenly be provided with three protuberances 91 in the ring on this activity friction plate 9 week, and this rotating main body bottom is respectively equipped with corresponding groove, is convenient to this activity friction plate 9 and endwisely slips and radially be set in to spline this rotating main body 1.
This cam bit 4 also is respectively equipped with gear point 41 and the positioning convex portion 61 of being convenient to limit rotation with base 6, this concave wheel piece 5 slotted eyes are passed in these positioning convex portion 61 upper ends, when this cam bit 4 rotates, gear point 41 can touch this positioning convex portion 61 on this cam bit 4, and this rotating main body 1 can only be done 0-360 ° relative to this base 6 and rotates like this.
Because this rotating main body 1 is generally the zinc alloy material with base 6, do not possess wear-resisting property, so rotation location between this rotating main body 1 and this base 6, mainly realize by this fixed friction sheet 8, movable friction plate 9 and a plurality of second dish-shaped shell fragment 10.
Operating principle of the present invention is: swinging mounting 31 is fixed on the computer liquid crystal displayer curtain, when LCD Display is axially opened, drives swinging mounting 31 axial rotation, and this state is the notebook computer open mode.Radial rotating computer liquid crystal displayer curtain drives this rotating main body 1 by swinging mounting 31 and makes radial rotary.Because cam bit 4 is fixing by riveting method and this rotating main body 1, cam bit 4 is followed rotating main body 1 and is rotated together, when rotating beginning, the boss 42 of cam bit 4 climbs out from concave wheel piece 5 upper grooves 51, the relative distance of 6 of rotating main body 1 and bases is increased, thereby reach the purpose of lifting liquid crystal screen.When rotating main body 1 rotated to 180 °, the boss 42 of cam bit 4 entered in the groove 51 on the concave wheel piece 5 again, and this moment, rotating main body 1 returned to initial height.Rotating main body 1 continues rotation, repeats above-mentioned motion state, and when rotating 360 degrees, gear point 41 interacts with positioning convex portion 61 on the cam bit 4, reaches the backstop effect.Toward back rotation computer liquid crystal displayer curtain, repeat above-mentioned motion state.Because rotating main body 1 angle of swing is 360 °, thus the backstop position need be assemblied in the mechanism with manner, to reach the purpose of 360 ° of backstops.
