Specific implementation mode
Please referring to Fig.1-2, the utility model is about a kind of yo-yo, including central rotating shaft 1 and two central rotating shafts 1, and two
A rotary body 2 is symmetricly set on the both ends of central rotating shaft 1, and rope is connected among central rotating shaft 1, and rotary body 2 includes interior turns
The center of disk 21, inner rotary table 21 is recessed inwardly relative to edge, and 1 both ends of the central rotating shaft are arranged with base bearing 23, interior turn
21 outer surface center of disk is equipped with collar bush 22, and inner rotary table 21 is socketed in by collar bush 22 on base bearing 23 to be connected with central rotating shaft 1
It connects;
The rotary body 2 further includes outer cover sheet 25, and 25 medial center of outer cover sheet is installed with time axle sleeve 27, the inner rotary table 21
Medial center is installed with protruding shaft 24, and 24 end of protruding shaft is arranged with time bearing 26, and the outer cover sheet 25 is socketed in by secondary axle sleeve 27
It is covered with inner rotary table 21 on secondary bearing 26 and closes connection;Outer cover sheet 25 and the lid of inner rotary table 21 close and form the hollow cavity 29 that amplifies, described
The side of outer cover sheet 25 is equipped with venthole 28, and venthole 28 is perpendicular to central rotating shaft 1;The edge of the outer cover sheet 25 is also socketed with
Elastic rubber ring 3,3 outside of the elastic rubber ring are installed with arc convex portion;
The central rotating shaft 1 is arranged with power coil 11, and each circle coiling plane of power coil 11 is flat with central rotating shaft 1
Row, and the output end of power coil 11 is connected with LED12 control chips, the output end of LED12 control chips is connected with LED12,
11 outside of the power coil is also arranged with hollow wrapping post 13, and 13 both ends of the wrapping post are solid with two inner rotary tables 21 respectively
Fixed connection, 13 inside of wrapping post is opposite to be installed with anisotropic opposite arc-shaped permanent magnet 14.
The yo-yo makes wrapping post 13 and rotary body 2 quickly rotate when in use, by pull rope, one in wrapping post 13
Anisotropic opposite arc-shaped permanent magnet 14 also will quickly be rotated, larger rotating speed will be generated between power coil 11 and wrapping post 13
Difference, power coil 11 is by the fly-cutting magnetic line of force, and output voltage supply LED12 control chips light LED12, due to pure cutting magnetic
The generating efficiency of the line of force is much larger than still immature vibration generating device, which can use without adding battery
Relatively high power is carried out in journey self-generating, to support the colorful of more LED12 to illuminate;
When yo-yo rotates, always there is venthole 28 upward, also have venthole 28 downward, venthole 28 is in vertical motion process
The air-flow across venthole 28 is will produce, in addition the quick rotation of yo-yo, because that can will be generated corresponding " whirling " along with action
Airflow noise, the airflow noise of " whirling " can seem louder by the effect of amplifying for the cavity 29 that amplifies, and player actions are got over
Consummation, speed are faster, the more apparent more entertaining of sound;
By being arranged independently of the protruding shaft 24 except base bearing 23 on inner rotary table 21 so that outer cover sheet 25 can be relative to
Inner rotary table 21 is rotated alone, i.e., player can pinch rotation of the outer cover sheet 25 of yo-yo without influencing inner rotary table 21, increase
More playing methods are added, have been conducive to the performance of more fancy skills, increase playability;
Arc convex portion on elastic rubber ring has elasticity, can be played when yo-yo is hit slow well
Punching acts on, and can effectively prevent spallation after yo-yo is hit.
In the present embodiment, the LED12 is fixed on central rotating shaft 1.
LED12 is fixed on central rotating shaft 1, keeps LED12 and shaft, power coil 11 opposite when yo-yo rotates
Static, LED12 is not susceptible to damage.
In the present embodiment, clump weight, the gross weight of the clump weight and power coil 11 are provided in the power coil 11
Total weight of the amount more than the wrapping post 13 and rotary body 2.
The total weight of the clump weight and power coil 11 is more than the total weight of the wrapping post 13 and rotary body 2, to
Make, to make wrapping post 13 and inner rotary table 21 when rotated, due to inertia difference, wrapping post 13, inner rotary table 21 and power coil
11 generate larger speed discrepancy, improve the speed of 11 cutting magnetic line of power coil, power generation speed is faster.
In the present embodiment, the clump weight deviates the axis setting of power coil 11.
The clump weight deviates the axis setting of power coil 11, to make power coil 11 under the effect of gravity, can grow
Time stablizes the position for keeping clump weight downward, and power coil 11 is further made to be not easy to rotate.
In the present embodiment, the arc convex portion is set as no less than three, and is evenly distributed on elastic rubber ring 3.
It three or more arc convex portions, can be to each side of yo-yo when hitting since elastic force acts on
Play cushioning effect very well.
In the present embodiment, the base bearing 23 is arranged with primary elastomeric circle 211 in the corresponding position of collar bush 22.
Primary elastomeric circle 211 increases the relative friction between base bearing 23 and collar bush 22, main when inner rotary table 21 being made to rotate
Coordinate between bearing 23 and collar bush 22 and more stablizes.
In the present embodiment, the protruding shaft 24 is arranged with time rubber ring 251 in the corresponding position of secondary bearing 26.
Secondary rubber ring 251 increases the relative friction between protruding shaft 24 and secondary axle sleeve 27, makes outer cover sheet 25 with respect to inner rotary table
When 21 rotation, coordinates between protruding shaft 24 and secondary axle sleeve 27 and more stablize.
In the present embodiment, the venthole 28 is uniformly distributed along the circumferential direction of inner rotary table 21.
Along the equally distributed venthole 28 of the circumferential direction of inner rotary table 21, always there is venthole 28 upward when yo-yo being made to rotate,
Always there is venthole 28 downward, venthole 28 will produce the air-flow across venthole 28 in vertical motion process, generate corresponding gas
Stream sound.
Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model
Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
It protects in range.
