Description

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 amusement ball game for exercising wrist of tempering health-care effect.

At present, the ball game for exercising wrist that has a kind of entertainment body-building to use on the market, it mainly constitutes the spherical shell of hollow by base and loam cake, in housing, be installed on the two-section minor axis, two minor axises are in line and preferably through the diameter of spherical shell, be a spherical spinner between two minor axises, rotor can rotate around minor axis, the line between deviation of gravity center two minor axises of rotor.Thereby after turning over, the rotor of this toy wrist is produced spread effect to reach the effect of body-building because its deviation of gravity center rotation will produce outside centrifugal force.But there is following shortcoming in this ball game for exercising wrist: 1, because rotor rotates with respect to minor axis, when rotor high-speed rotated, the friction between minor axis and rotor was very serious, had greatly shortened the life-span of toy; 2, because minor axis is fixed on the spherical shell, and the centrifugal force that is produced when rotor rotates in same plane, when acting on the wrist, feels very dull all the time like this, is easy to make the people to feel dull, lose interest, so its exercise and entertainment effect are not so good; 3, temper purpose because it reaches by centrifugal force, and the big more centrifugal force of spinner velocity is also big more, when ball rotates at a high speed, slips out of the hand as making ball because of carelessness, is easy to injure other people, so safety inadequately.

The purpose of this utility model is the ball game for exercising wrist that a kind of long service life, safety coefficient height is provided, has more amusement and body-building effect.

The purpose of this utility model can be achieved as follows: this ball game for exercising wrist mainly is made up of spherical shell, rotor and the rotating shaft of the hollow that is made of base and loam cake.Wherein the spherical shell inwall has one to enclose the inner groove of the indent that is fitted in by base and loam cake, and opening is arranged at the top of loam cake.Described rotor is positioned at spherical shell, be processed into sphere, in the weightening finish device is arranged, its center of gravity is the centre of sphere.Described rotating shaft is symmetrical in its axle center, and be fixed on the rotor, and overlap with rotor c.g., be exposed at the outer rotating shaft two of rotor and bring out step formation smooth surface and the less two axial ends of its external diameter, the part spherical crown that leans on two axial ends place rotor is along being cut and substituted by at least two lobe blades perpendicular to rotor shaft direction.Rotor overlaps resilient horizontal loops through rotating shaft, the aperture of two side perforations is littler and bigger and can pass horizontal loops respectively for two axial ends than the external diameter of two axial ends than the external diameter at rotating shaft middle part on the horizontal loops, and the length at the big rotating shaft middle part of external diameter is littler and bigger than rotor diameter than horizontal loops internal diameter.Circle flange in the middle of the horizontal loops outside places in the inner groove with the sponson that passes horizontal loops of two axial ends, and is matched in clearance between the neighboring of the upper and lower edge of horizontal loops and the spherical shell inwall.The length of rotating shaft is less than the groove footpath of inner groove, and the external diameter of rotating shaft two axial ends is less than the height of inner groove notch.Described rotor surface has the annular groove that is used to lay stay cord together, also has a counterbore that is used to assign stay cord one end in the annular groove, the ring heart of annular groove overlap with the rotating shaft center of gravity and the annular groove face vertical with rotating shaft.

After adopting said structure, because rotating shaft is to be fixed on epitrochanterianly, their center of gravity is in geometric center of rotor substantially, does not throw away centrifugal force so time rotational can not produce, and does not injure other people even high speed also can not throw away because of slipping out of the hand when rotating outward, has guaranteed security.Rotor and rotating shaft are in the high speed rotation, also do with respect to spherical shell rotation and two axial ends scroll-up/down in inner groove alternately also, thereby spherical shell is produced the universal rotating force that a upheaval rises and falls, a kind of stimulation pleasant sensation is arranged in hand, increased interest, and hand has been played a role in health care.In addition, rotating shaft makes rotor rotation with the rolling form in inner groove, and replacing sliding to roll to significantly reduce friction, has improved the service life of ball game for exercising wrist.This ball game for exercising wrist integrates entertainment body-building, and manufacturing is simple, cost is low, and old children is all suitable, so market prospects are wide, and potentiality to be exploited is big.

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

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

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

In Fig. 1 and Fig. 2, the base 2 of ball game for exercising wrist and loam cake 3 all are to make the spherical shell 1 that hemispherical Shell constitutes hollow together with transparent plastics.Wherein the connection between base and the loam cake is along the circumferential direction respectively to cut a circle formation water jacket 18 and an inside groove inside and outside near the port of base, and the inner circle that also along the circumferential direction cuts forms inside groove near the loam cake port, like this base and loam cake unification time-out are made the inside groove engagement of the water jacket of base with loam cake, then with ultrasonic wave they formation spherical shells that forces together, at this moment at the inwall of spherical shell inner groove 5 with regard to the indent that constitutes a circle and fit in by the inside groove of base and loam cake.Be cut into flatly for making ball game for exercising wrist place steady base at ordinary times, the top of loam cake is then cut partly spherical one-tenth one opening 4.Be used to place rotor 6 in the spherical shell of hollow, rotor is made the sphere spheroid with plastics or other materials, and inside adds the weightening finish device of a metal, to increase the deadweight of rotor, the center of gravity that will guarantee rotor simultaneously is its centre of sphere, and the device that here increases weight is made the cylinder of a hollow.Be fixed with rotating shaft 7 on the rotor, the axis coinciding of the axle center of rotating shaft and weightening finish device, the symmetry axis of the rotating shaft made from alloy is its axle center, and the center of gravity of rotating shaft is overlapped with the center of gravity of rotor.Be exposed at two having brought out step and form two axial ends 17 of rotating shaft of rotor spheroid outside, its length unanimity, smooth surface, its external diameter is littler than the external diameter at rotating shaft middle part.Every limit is respectively replaced by 4 lobe blades 8 along cut also perpendicular to rotor shaft direction at the part spherical crown near two axial ends place rotor spheroid, 4 lobe blades are fixed in fact earlier on the hollow shaft, then vertically respectively the cover fix on rotating shaft one end, the edge of blade becomes lonely shape along the circumference of spheroid.Therefore, rotating shaft is actually and is fixed on epitrochanterian through increasing weight device and blade, put in the part in the weightening finish device and put in the inwall that edge partly is close to the weightening finish device so the 4 lobe blades on rotor both sides all have, during manufacturing, as long as mold cavity is just filled with and can be fixed on rotating shaft on the rotor, like this rotor be actually into hollow and be divided into 4 parts by blade, if the weightening finish device is solid certainly, rotating shaft and blade directly are fixed on the rotor and get final product.Rotor is with the flexible spacing horizontal loops 9 that is used for of plastics through rotating shaft, there is perforation 10 both sides on the horizontal loops, the aperture of perforation is bigger and littler than the external diameter at rotating shaft middle part than the external diameter of the two axial ends of rotating shaft, make perforation rotating shaft middle part that the two axial ends of rotating shaft can pass horizontal loops then can not, play position-limiting action.The length at the middle part that the rotating shaft external diameter is big is more a little bit smaller than horizontal loops internal diameter, and the position that guarantees to have a surplus between them get final product, because excessive then the friction with the horizontal loops generation easily of the length at middle part too smallly then easily walked up and down.And the length at the big middle part of rotating shaft external diameter is bigger than rotor diameter, has guaranteed that therefore rotor can freely rotate with respect to horizontal loops.Because the length of whole rotating shaft is than big few of the internal diameter of horizontal loops, and horizontal loops is flexible, therefore as long as horizontal loops is done to be out of shape a bit slightly can be with horizontal loop sleeve on the two axial ends of rotating shaft.There is a circle flange 11 middle part, the horizontal loops outside, and the position of the flange of boring a hole makes flange form breach, and two axial ends has one section sponson after passing horizontal loops, and this sponson is positioned on the limit of inner groove with flange.And be matched in clearance between the inwall of the circumferential periphery of the upper and lower edge 12,13 of horizontal loops and spherical shell, as long as this gap can guarantee horizontal loops and can freely rotate with respect to the spherical shell physical efficiency, because when the gap is too big, horizontal loops is just rocked in spherical shell easily, make rotor and rotating shaft also easily rock, and too hour, horizontal loops easily produces friction with the spherical shell inwall, and then rotation can not be freely.Simultaneously, the length of rotating shaft should directly and preferably be lacked 0.5-0.6mm less than the groove of inner groove, makes the end of rotating shaft be difficult for rubbing with the bottom land generation; In addition, the external diameter of rotating shaft two axial ends preferably also is few 0.5-0.6mm less than the height of inner groove notch, and two axial ends just can have the space of bob in inner groove like this.From the above, whole rotor just is positioned at the spherical shell middle part in the base that is pressed in inner groove of the two axial ends by rotating shaft, the relative limit and the two axial ends that add horizontal loops can be rolled on the inner groove base, rotor not only can be in spherical shell rotation freely but also can rotate with respect to spherical shell with horizontal loops, so except that the upper and lower surface of inner groove, should process enough smooth smoothly in the spherical shell to reduce friction.In addition, the annular groove 14 that is used to lay stay cord 15 is together arranged on the rotor surface, a counterbore 16 that is used to assign stay cord one end is arranged in the annular groove, the ring heart of annular groove overlap with the rotating shaft center of gravity and the annular groove face vertical with rotating shaft, so annular groove just is positioned at the visual place of opening of loam cake.

During use, aperture position at loam cake injects counterbore to stay cord one end, rotary rotor, make stay cord in annular groove around several circles, take the spherical shell of ball game for exercising wrist then on the other hand, another other end that pulls stay cord spurs stay cord fast, stay cord breaks away from rotor like this, rotor then obtains a bigger initial velocity, make the rotor quick rotation, at this moment under the effect of inertia of buoyancy that blade rotation produces and stay cord pulling force, one end of rotating shaft then rolls at the lower surface of inner groove at the upper surface rolling other end of inner groove, the two ends of rotating shaft are back and forth alternately on inner groove, lower surface rolls, thereby makes rotor drive rotor again in rotation and horizontal loops is rotated with respect to spherical shell along the direction of horizontal loops together; At this moment, make the wrist of holding ball game for exercising wrist do gyration by certain rhythm and rule again, to accelerate the rotation of rotor along the horizontal loops direction, and then accelerated the spinning motion of rotor again, good the same such as playing on a swing, when the swing direction of motion constantly applies external force, swing will swing higher and higher, as a same reason, as long as constantly do the wrist gyration along the rotation direction of rotor, the rotation of rotor and will change faster and faster along the velocity of rotation of horizontal loops direction.Therefore, no matter in the inner groove which point rotating shaft one end forward on, all can act on downward power of this point, and be relative with it, the rotating shaft other end also can act on the power that makes progress in its present position, whole like this spherical shell just is subjected to the power that a upheaval is circled round, and speed is big more, and two power are just big more, these two power act on the wrist by shell again, so both reached the effect of taking exercises, given a kind of enjoyment that enjoys endless aftertastes of people again, and therefore played and more want and play.
