Embodiment
In conjunction with Fig. 1, Fig. 2 and Fig. 3; Below further describe: a kind of rotation and switching mechanism that connects the computer liquid crystal screen; Be made up of a center roller (21,22) and rotating main body 1, the relative end of this center roller (21,22) is individually fixed in this rotating main body 1 top, and the other end of this center roller (21,22) passes this swinging mounting 31, the first oil groove sheet 361 respectively successively, recessedly takes turns 32, behind cam 33, the second oil groove sheet, 362, a plurality of first dish-shaped shell fragment 34 and the 3rd oil groove sheet 363; Be rotated with nut 35; This swinging mounting 31 with 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, second be respectively equipped with corresponding qualification face with the 3rd oil groove sheet (361,362,363); Be convenient to this cam 33 and endwisely slip respectively with the 3rd oil groove sheet (361,362,363) with this first, second 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, is convenient to through 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 reversed in positioned of connection.
After this rotating main body 1 bottom is passed cam bit 4, concave wheel piece 5, base 6, fixed friction sheet 8, movable friction plate 9 and a plurality of second dish-shaped shell fragment 10 successively; Be fixed in fixed plate 7 through screw 17; This cam bit 4 is fixed in this rotating main body 1 through the riveted joint mode; And this concave wheel piece 5 is fixed in this base 6 through the riveted joint mode; And this cam bit 4 is respectively equipped with boss 42 (as shown in Figure 3) and groove 51 (as shown in Figure 1) with concave wheel piece 5 corresponding surfaces, and this fixed friction sheet 8 is fixed in this base 6, evenly is 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 the retaining point 41 and 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; Retaining point 41 can touch this positioning convex portion 61 on this cam bit 4, and this rotating main body 1 relative this base 6 can only be done 0-360 ° of rotation like this.
Because of this rotating main body 1 is generally the zinc alloy material with base 6, do not possess wear-resisting property, so rotation positioning between this rotating main body 1 and this base 6, mainly realize through this fixed friction sheet 8, movable friction plate 9 and a plurality of second dish-shaped shell fragment 10.
The operating principle of the utility model is: swinging mounting 31 is fixed on the computer LCD Display, when LCD Display is axially opened, drives swinging mounting 31 axial rotation, and this state is the notebook computer open mode.Radially rotate the computer LCD Display, drive this rotating main body 1 through swinging mounting 31 and do radially rotation.Because cam bit 4 is fixing through riveted joint mode 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, and the relative distance of 6 of rotating main body 1 and bases is increased, thereby reaches the purpose of lifting liquid crystal screen.When rotating main body 1 rotated to 180 °, the boss 42 of cam bit 4 got in the groove 51 on the concave wheel piece 5 once more, 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 °, retaining point 41 interacts with positioning convex portion 61 on the cam bit 4, reaches the backstop effect.Toward back rotation computer LCD Display, repeat above-mentioned motion state.Because rotating main body 1 angle of swing is 360 °, thus backstop position need be assemblied in the mechanism with manner, to reach the purpose of 360 ° of backstops.
