See also Fig. 1 to shown in Figure 6, be of the present utility model one preferable possible embodiments, the toy whirligig among this embodiment comprises a base 1, one motor 2, a transmission device 3, an eccentric wheel 4, a connecting rod 5, a reset switch 6 and an inner rotary cover 7.This motor 2, transmission device 3, eccentric wheel 4, connecting rod 5 and reset switch 6 are arranged on this base 1 and are positioned at this base 1 and the space of this inner rotary cover 7 fastening formation.
The bottom of this base 1 is circular, and its center is provided with one first connecting axle 11.
This motor 2 is a common motor, which is provided with a motor drive shaft 21, and the bottom of this motor 2 is fixed on this base 1, and this motor 2 is powered to it by a power supply circuits (not shown).
This transmission device 3 comprises a small belt pulley 30, tooth belt wheel 32,1 first gear 33, one second gear 34, one the 3rd gear 35, a square shaft 36 and a shell 37.This small belt pulley 30 is fixedly sleeved on the motor drive shaft 21 of this motor 2, rotates thereby this motor drive shaft 21 can drive this belt pulley 30 when rotating thereupon; Two parts up and down of this tooth belt wheel 32 are respectively a fixedly connected big belt pulley 321 and one first pinion 322, and this big belt pulley 321 links to each other with this small belt pulley 30 by belt; This first gear 33 is the pair of lamina gear, and it comprises a fixedly connected first gear 331 and one second pinion 332 up and down, this first gear 331 and these first pinion, 322 engagements; This second gear 34 also is the pair of lamina gear, and it comprises a fixedly connected second largest gear 341 and a third pinion 342 up and down, this second largest gear 341 and these second pinion, 332 engagements; The 3rd gear 35 is an individual layer gear, and the center of the 3rd gear 35 is provided with a square hole, the 3rd gear 35 and these third pinion 342 engagements.This square shaft 36 is a square cylinder, and the one end is fixed on the square hole at the 3rd gear 35 centers.This shell 37 coats the periphery that is arranged on whole transmission device 3.
This eccentric wheel 4 is a circular wheel, its center is provided with and this square shaft 36 corresponding square sleeve joint holes 41, these eccentric wheel 4 more off-centered biasing posts 42 that are provided with, the exterior periphery of this eccentric wheel 4 is provided with a protuberance 43, and this eccentric wheel 4 is connected to the other end of this square shaft 36 by this sleeve joint hole 41.
This connecting rod 5 is the connecting rod of a circular arc, and its end that links to each other with this eccentric wheel 4 is provided with one first connecting hole 51, and the other end is provided with one second connecting hole 52, and the biasing post 42 on this first connecting hole 51 and this eccentric wheel 4 flexibly connects.
This reset switch 6 is arranged on the outside of this eccentric wheel 4, makes that this protuberance 43 touched mutually with this reset switch 6 when this eccentric wheel 4 turned to a certain angle.This reset switch 6 is provided with a control number of times, and when the number of times that touches when this reset switch 6 and this protuberance 43 equaled this this control number of times, the power supply circuits that this reset switch 6 is controlled these whirligigs were stopped power supply, thereby this eccentric wheel 4 is stopped the rotation.
This inner rotary cover 7 is a columned cover body, it comprises the top board 71 of a circle and the sidewall that forms around this top board 71, the center of this top board 71 is provided with one the 3rd connecting hole 72, an off-centered place is provided with one second connecting axle 73 on this top board 71, this second connecting axle 73 flexibly connects with second connecting hole 51 on this connecting rod 5, and the 3rd connecting hole 72 is movably connected on first connecting axle 11 on this base 1.
When using, motor 2 is powered, motor drive shaft 21 is driven rotation, thereby makes small belt pulley 30 rotate thereupon, and small belt pulley 30 driven gear belt pulleys 32 rotate.Because first pinion 322 of tooth belt wheel 32 meshes with the first gear 331 of this first gear 33, so the rotation of belt pulley 32 has just driven the rotation of first gear 33.In like manner first gear 33 has driven the rotation of second gear 34 that is engaged with, second gear 34 driven again be engaged with the rotation of the 3rd gear 35.The rotation of the 3rd gear 35 makes the square shaft 36 that is fixed in its center rotate thereupon, and this square shaft 36 has driven the rotation of the eccentric wheel 4 of clamping with it again.The end that the rotation of this eccentric wheel 4 makes this connecting rod 5 be attached thereto rotates thereupon, because the other end of this connecting rod 5 links to each other with this inner rotary cover 7, be that rotate to the direction identical with eccentric wheel 4 rotation directions in the axle center with this first connecting axle 11 again thereby promoted this inner rotary cover 7.But because the restriction of the length of this connecting rod 5, when this inner rotary cover 7 went to an extreme angles, this connecting rod 5 spurred this inner rotary cover 7 again and turns round in the opposite direction.When should this inner rotary cover 7 returning back to an extreme angles, this connecting rod 5 spurs this inner rotary cover 7 again and rotates to the direction identical with eccentric wheel 4 rotation directions.By that analogy, when motor 2 rotated, inner rotary cover 7 will be the action that the axle center threshes left rotation and right rotation with first connecting axle 11.Because this eccentric wheel 4 when whenever rotating a circle, the protuberance 43 on this eccentric wheel 4 touches this reset switch 6 once again, and when the number of times that is touched when this reset switch 6 equaled the control number of times of this reset switch 6, this inner rotary cover 7 promptly can stop operating.
And when any one in first connecting hole 51 on the connecting rod 5 and the distance between second connecting hole 52, the 3rd connecting hole 72 on the inner rotary cover 7 and the distance between second connecting axle 73 and sleeve joint hole 41 on the eccentric wheel 4 and the distance between the biasing post 42 changed, the size of the left rotation and right rotation angle of this inner rotary cover 7 can change.
The reciprocal dynamic effect of rotation about the structure that toy whirligig of the present utility model cooperates with connecting rod 5 by self eccentric wheel 4 can make the toy that is attached thereto realize, and also can regulate the angle of toy left rotation and right rotation by the distance of regulating between the connecting hole, thereby increase the interesting and ornamental of toy.
Yet; the above only is a preferable possible embodiments of the present utility model; and unrestricted protection domain of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content have been done changes, all be included in the protection domain of the present utility model.
