Embodiment

At first see also Fig. 2 to shown in Figure 4, the utility model is a kind of LCD automatic changeover, is installed in the pedestal 20 of LCD, and links this LCD 30, and turn to about making these display 30 energy automatically, wherein this automatic changeover 10 includes:

One box body 1 has an accommodation space 11;

One gear set 2, be mounted in this accommodation space 11, this gear set 2 includes two tooth sectors 21, an emergency gear 22, a transmission gear 25, a reduction gearing 23, reaches an output gear 24, this output gear 24 is a sector gear in the present embodiment, and this output gear 24 upwards is provided with efferent 241, and efferent 241 is two protruding axles 241 in present embodiment;

One power unit 3 is located in this accommodation space 11, and links with gear set 2, to drive this gear set 2;

One rotary unit 4, be mounted on this box body 1 top, and include a chassis 41, long arc-shaped holes 411 with several projections, coil 42 on one, on relative two protruding axles 241 positions, be provided with two through holes 421, these through holes 421 can hold this two protruding axle 241, and on the position of relative these long arc-shaped holes 411, be respectively equipped with a through hole 422, one is folded on this tumbler 43 on

dish

42 and 41 on chassis, can make to coil 42 mechanical compliances of reducing friction and freely rotate, and reaches several binding members 44, pass long arc-shaped holes 411 and through hole 422 respectively in regular turn, and will go up dish 42 and chassis 41 engages together, and should go up dish 42 and rotate the time, these binding members 44 can slide in this long arc-shaped holes 411;
