Description

Multi-functional ball game for exercising wrist

The utility model relates to a kind of body-building recreation toy, particularly a kind of have hand is had the multi-functional ball game for exercising wrist of amusement of tempering health-care effect.

It is the ball game for exercising wrist of ZL99240360.X that State Intellectual Property Office disclosed the patent No. on August 30th, 2000, it mainly comprises the spherical shell of a band opening, be placed on the annulus in the spherical shell, one rotating shaft holding is on annulus, adorning one in rotating shaft turns, this sub-fraction of turning can be exposed the opening of spherical shell, on annulus, also be fixed with magnet, on turning, be provided with silicon steel sheet, on silicon steel sheet, be wound with a coil at least, at least connect two light emitting diodes at the two ends of coil, can use palm by after turning of shell nozzle place exposed in startup from top to bottom during use, utilize the rotation of wrist to make the acceleration of turning again, be similar to gyro, can produce the power rotation, coil produces electric current, make led lighting, but the structure of magnet and coil is not ideal enough: 1, coil is the closed magnetic line of force that the opposed two blocks of magnet that are distributed in the circle diameter two ends of cutting constitute, because two magnet apart from each others, and magnetic field intensity hour, power shortage then, as increasing magnetic field, then the attraction of magnet and silicon steel sheet is also big, makes the difficulty of turning rotate even can't rotate, magnetic field intensity is too big simultaneously, and human body is had infringement; 2, the rotating speed of turning will improve, and needing relatively steadily promptly turn need good concentricity, on silicon steel sheet is contained in and turns, be difficult on the technology reach with one heart, thus the power shortage of having influence on, reaching with one heart then, the technology cost increases greatly; 3, coil also makes manufacturing process complicated on turning.4, the at a high speed rotation of turning, the long-term use of silicon steel sheet easily has fragment to come off, and throws away and hurts sb.'s feelings, inadequately safety.5, the ball game for exercising wrist interest is also relatively more dull.

The purpose of this utility model be for overcome above-mentioned shortcoming provide a kind of safe in utilization, induced-current and voltage by force and stable, technology is simple, the ball game for exercising wrist with body-building recreation function.

The purpose of this utility model can be achieved as follows: this ball game for exercising wrist mainly comprises spherical shell, be placed on the annulus in the spherical shell, one rotating shaft holding is on annulus, in rotating shaft, adorn a rotor, also be fixed with magnet on the annulus, also be fixed with coil on the rotor, at least connect two light emitting diodes at the two ends of coil, it is characterized in that: described magnet is passed by the rotating shaft axle head on annulus, the coil stationary that is complementary with magnet near the position of magnet, comprises magnetic field N, the S utmost point of at least one group of magnet on the surface of the magnet relative with coil on rotor.

As further improvement of the utility model, the two ends of the coil of this ball game for exercising wrist also are connected with loudspeaker with the music electronic plate.

The utility model utilizes the power rotation of ball game for exercising wrist, make internal structure become a small generator, be located at magnet on the annulus and be equivalent to the stator of generator, be located at epitrochanterian coil and be equivalent to the rotor of generator, wherein, magnet is fixed on rotating shaft axle head on the annulus and passes the magnetic field N that comprises at least one group of magnet on the surface of position and magnet, the S utmost point, coil just is located at position close with magnet on the rotor, at least connect two light emitting diodes at the two ends of coil, its great advantage is: the coil during rotor rotation on it only cuts the magnet surface N that is complementary with it, the magnetic line of force that the S utmost point forms just can produce induced voltage and electric current makes led lighting.Coil winds in advance, volume and weight is all very little, just can be fixed on the rotor through simple process, reduced manufacturing cost, used saferly, rotor is proofreaied and correct through equilibristat, guaranteed concentricity, rotor is easily realized rotation at a high speed, and coil abuts against the magnet magnetic line of force the strongest the closeest position again, and the abundance that has guaranteed supply of electric power is with stable, make the structure of magnet and coil become better, avoided the deficiencies in the prior art, long-term exercise can strengthen the strength of wrist and arm, strengthens the grip of palm and finger, promote the blood circulation of arm and even whole body, body health benefits can increase interest again, integrates body-building recreation.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the structural representation of the multi-functional ball game for exercising wrist of the utility model;

Fig. 2 is another schematic perspective view of the multi-functional ball game for exercising wrist of the utility model.

In Fig. 1 and Fig. 2, the spherical shell 1 of ball game for exercising wrist is made of base 2 and loam cake 3, opening 4 is arranged on it, rotating shaft 7 holdings are on annulus 9, fixed rotor 6 in the rotating shaft, the fraction of this rotor can expose the opening of spherical shell, magnet 5 is fixed on the annulus 9 and is passed by rotating shaft axle head 17, the rotating shaft axle head passes again bores a hole 10 on the annulus, the coil 11 that is complementary with magnet is fixed on the rotor 6 position near magnet, it is the end of the blade 8 of rotor, and on the limit near rotating shaft, the magnetic field N that comprises at least one group of magnet on the surface of the magnet relative with coil, the S utmost point, magnet surface has three groups of magnetic field N in the present embodiment, the S utmost point, the two ends of coil are connected with the both positive and negative polarity of light emitting diode.The weight of coil is very little, is cut out one on the rotor and is used to place coil, and the weight that is cut out is the same with coil, even the different balance weight that also can utilize comes balance, proofreaies and correct with equilibristat then, till balance, to guarantee the concentricity of rotor.In order to increase electric power, can set up to 2,3,4 or more a plurality of with the coil that each magnet is complementary, be fixed on the rotor and rotating shaft around get final product, also can set up more groups of magnetic field N, the S utmost point to increase electric power at magnet surface.For fixed magnet, annulus has link stopper 12 on rotor, and boss 13 is arranged on the link stopper, and magnet is enclosed within on the boss fixing.For ease of starting, open annular groove 14 on the rotor one, place annular groove counterbore 16 to get final product with an end of stay cord 15.

In addition, in order to increase the interest of ball game for exercising wrist, the two ends of coil also are connected with loudspeaker with the music electronic plate, can insert various music in advance on the smart card, the needs that adapt to different crowd, during especially as present, not only can enjoy beautiful music but also can experience fine blessing, integrate body-building recreation especially.
