Abstract

The utility model provides a yoyo filled with weight counterbalance fluid. The yoyo comprises two symmetrical rotating bodies, a connecting shaft and a bearing, wherein each rotating body comprises a spherical crown body and an end cover, a hollow cavity for loading fluid is defined by the spherical crown body and the end cover, the hollow cavity is filled with the weight counterbalance fluid, the end cover is provided with at least two liquid injecting holes, the liquid injecting holes are sealed by elastic bodies such as rubber pistons, the end cover is a transparent body, the inner surface or the outer surface of the end cover is provided with a plurality of bulge-shaped lattices which are in circular distribution, and the center position of the spherical crown body or the end cover is provided with a luminous body which is connected with a power supply. Colorful light rings can be formed after lights are refracted and reflected through the fluid and then retracted through the bulge-shaped lattices, and thus the attraction is increased. According to the utility model, by filling the weight counterbalance fluid in the hollow cavities of the rotating bodies for weight counterbalance, thus the weight of the rotating bodies is uniformly distributed, and the rotating stability is better.

Description

Fluid counterweight Climbing top Yo-Yo

Technical field

The utility model relates to a kind of game toy Climbing top Yo-Yo, specifically is a kind of Climbing top Yo-Yo of perfusion of fluid counterweight.

Background technology

Climbing top Yo-Yo is made up of interior two rotary bodies that light-emitting device is housed, the connecting axle and the bearing that connect two rotary bodies.In order to make the rotation of Climbing top Yo-Yo high-speed smooth ground, rotary body should have suitable weight, and center of gravity should accurately drop in the rotating shaft and produce bigger centrifugal force when rotated as far as possible, therefore need carry out counterweight to rotary body.

In the existing Climbing top Yo-Yo, the parts of counterweight effect basically all are to be processed by the bigger metal material of proportion, for example: the disclosed Climbing top Yo-Yo of Chinese patent CN2894776U, rotary body comprises inner disc and outer shroud, the outer shroud of employing metal material plays the effect of counterweight; The Climbing top Yo-Yo rotary body of CN2917723U comprises inner disc and is arranged on the side cover in the inner disc outside, is equipped with several caulking grooves on the submarginal madial wall of inner disc, and is equipped with the mass of being processed by the bigger material of density like steel ball and so in the caulking groove; The disclosed Climbing top Yo-Yo of CN201088836U is clipped in middle weight stack between inside piece and the lateral film; The disclosed Climbing top Yo-Yo of CN201643680U, balancing disk and rotary body alloy external toroidal ring carry out counterweight to rotary body in the middle of adopting.

Because weight member all is a rigid material; When Climbing top Yo-Yo begins to rotate in inactive state; All parts that comprise weight member all need rotation function, and rotating speed promotes slowly when therefore beginning to rotate, when cancelling rotary acceleration; Rotation function discharges rapidly, therefore can only carry out the idle running of short time.

Summary of the invention

The purpose of the utility model be to provide a kind of can fast lifting when static rotating speed, when cancelling rotary acceleration, can slowly discharge the Climbing top Yo-Yo of rotation function.

The fluid counterweight Climbing top Yo-Yo of the utility model comprises two rotary bodies of symmetry, connects the connecting axle and the bearing of these two rotary bodies, and rotary body comprises ball-crown body and end cap, and ball-crown body and end cap surround the cavity of a loading liquid, and cavity is perfused with the counterweight fluid.

Can have at least two on the above-mentioned end cap with the rotational symmetric liquid injection hole of this Climbing top Yo-Yo rotating shaft core, liquid injection hole is sealed by elastomer such as rubber piston.

In the preferred version of the utility model, end cap is the trumpet-shaped transparent body, and the overshooting shape dot matrix is arranged on the inner surface of end cap or the outer surface, several annular spread that these overshooting shape dot matrix are the center of circle with this Climbing top Yo-Yo rotating shaft preferably.

Ball-crown body is the transparent body preferably.

Can also there be illuminator in the centre of ball-crown body or end cap and be provided with corresponding power supply.

The utility model makes the rotary body distribution of weight balanced through pouring into the counterweight fluid to the rotary body counterweight to rotary body, and rotational stabilization is better; In the process that is at play, Climbing top Yo-Yo can more steadily rotate, ability fast lifting rotating speed when static; When cancelling rotary acceleration, can slowly discharge rotation function, therefore improved the idle period; Handling is better, and ambient light or rotary body light shine on the end cap through the refraction and the reflection of counterweight fluid; Through the anaclasis and the interference of light of overshooting shape dot matrix, form the colorful ring of light, increased the sight and the playability of spheroid.

The specific embodiment

Fig. 1 illustrates a kind of embodiment of the utility model, and this Climbing top Yo-Yo comprises two rotary bodies 1,2 of symmetry, connects the connecting axle 3 and the bearing 4 of these two rotary bodies 1,2.Rotary body 1 is formed by ball-crown body 5 and end cap 6 seal combination, and ball-crown body 5 is the transparent body with end cap 6, and ball-crown body 5 and end cap 6 surround the cavity 7 of a loading liquid.Cavity 7 is perfused with counterweight fluid such as water, silicone oil, paste or fine sand, and the counterweight fluid can also be made into multiple color.

2 liquid injection holes 8,9 are arranged on the end cap 6, and with this Climbing top Yo-Yo rotating shaft core rotation symmetry, behind cavity 7 perfusion counterweight fluids, liquid injection hole 8,9 is by elastomer 10 sealings.

Because weight member all is a fluent material, when Climbing top Yo-Yo began to rotate in inactive state, ball-crown body 5 began rotation with end cap 6 rigid elements such as grade; But the counterweight fluid still remains static, and the rotary thrust that therefore needs is lower, and the Climbing top Yo-Yo rotating speed can promote rapidly; The counterweight fluid is just progressively rotation after hydrodynamics cutting slowly, and when cancelling rotary acceleration, the rotation function of fluid slowly discharges through fluid cutting back; Therefore rotating speed decline is also very slow, the rotating speed rotation that Climbing top Yo-Yo can be average, and the idle period of having improved Climbing top Yo-Yo greatly; Handling is better, and rotational stabilization is better.

End cap 6 can be designed to horn-like, and the overshooting

shape dot matrix

11,12,13,14 of 4 annular spread is arranged on the inner surface of end cap 6, and these overshooting shape dot matrix are that the center of circle distributes with this Climbing top Yo-Yo rotating shaft.Can also be provided with illuminator 15 and connect corresponding power supply in the centre of ball-crown body 5 or end cap 6.When Climbing top Yo-Yo rotated, the light of ambient light or illuminator 15 shone on the end cap 6 after the refraction and reflection of counterweight fluid; Through overshooting

shape dot matrix

11,12,13,14; The anaclasis and the interference of light, form the colorful ring of light, increased the sight and the playability of spheroid.
