Embodiment

By explaining the preferred embodiment of following the application, other objects and advantages of the present utility model will become clear Chu.

Fig. 1 is a kind of stereogram of whirligig of the utility model embodiment.Fig. 2 is that the utility model is specific A kind of explosive view of whirligig of embodiment.

As depicted in figs. 1 and 2, a kind of whirligig, including：First lid (1), there is the first endoporus

(11) and in axially extending the first extension (12) of first endoporus 11；Housing (2), there is the first through hole (21)；Bearing (3), there is the second through hole (31), and in embedded first through hole (21) of the bearing (3), Yi Ji Two lids (4), there is the second endoporus (41) and in axially extending the second extension (42) of second endoporus (41), described the Two extensions (42) are connected through second through hole (31) with first extension (12) of first lid (1), First endoporus (11) and second endoporus (41) insertion.The whirligig is in use, can be used single finger through the One endoporus 11 and the second endoporus 41, so as to avoid whirligig from coming off and break from finger tip.

It should be noted that first endoporus 11 and second endoporus 41 can be circle, or other rule Then shape, such as multi-edge column-shaped, ellipse etc., can also be irregular shape, such as shape adaptable with the shape of finger Deng.

Fig. 3 is a kind of front view of whirligig of the utility model embodiment.Fig. 4 is the utility model Fig. 3 A-A sectional views.Fig. 5 is the utility model Fig. 4 explosive view.

As shown in Fig. 3, Fig. 4 and Fig. 5, the maximum outline of first lid 1 and second lid 4 is circle, and The outside diameter of the outline is more than or equal to the external diameter of the bearing 3.Bearing 3 is wrapped in interior by the first lid 1 and the second lid 4 Side, the outer ring of bearing 3 and the junction of inner ring is avoided to be exposed to outside, so as to avoid accumulating dust between Internal and external cycle.

Certainly, the maximum outline of first lid 1 and second lid 4 can also be other shapes, but no matter Which kind of shape the outline is, as long as the outer ring of the bearing 3 and the junction of inner ring can be blocked.

As shown in figure 3, the outline of the housing 2 has multiple concave part 22a, can be stirred with finger concave part 22a come Rotate this whirligig.Preferably, above-mentioned multiple concave part 22a are arranged at the outer of housing 2 in a manner of centrosymmetric On profile, be advantageous to dynamic balancing when toy rotates.

As preferred embodiment, as shown in fig. 6, the outline of the housing 2 has waveform convex-concave portion 22b.

For the connected mode of the first lid 1 and the second lid 4, as shown in Figure 4 and Figure 5, first lid 1 with it is described Second lid 4 is threadedly coupled.Specifically, as shown in figure 5, first lid 1 is provided with internal thread part 14, second lid 4 The second extension 42 be provided with the external thread part 44 that is connected with the internal thread part 14.Wherein, the first extension 41 and second Extension 42 contacts with the second through hole 31 of bearing 3.

It is further preferred that it is provided with shrinkage pool portion 111, the internal thread towards the side of bearing 3 in first endoporus 11 Portion 14 is in the shrinkage pool portion 111.Accordingly, the outside dimension of external thread part 44 is less than the outer diameter ruler at the second extension 42 It is very little.After first lid 1 and the connection of the second lid 4, the first endoporus 11 and the second endoporus 41 seamlessly transit, and not only improve and improve this object for appreciation The visual effect of tool, junction can also be avoided to form wedge angle, so as to which wedge angle is pressed against and hinders finger when playing a part of avoiding using.

Certainly, the first lid 1 and the second lid 4 can also be attached using other mechanical connection manners, such as be used Mode connects for screw, interference fit connection or welding.

As shown in figure 5, first lid 1 at the inner ring end contact of the bearing 3 with being provided with the first lug boss 13, institute The second lid 4 is stated with being provided with the second lug boss 43 at the inner ring end contact of the bearing 3.First lug boss 13 and second is raised Portion 43 and the inner ring end contact of bearing 3, avoid the first lid 1 and the second lid 4 from being contacted with the outer ring of bearing 3 or housing 2, Be advantageous to improve the flatness of this toy rotation.As shown in figure 5, the height of projection of the first lug boss 13 and the second lug boss 43 is S, S scope are 0.1-3mm, and more preferable scope is 0.1-1mm, to be more highly preferred to, S 0.1-0.5mm, such as can be with Selected 0.2mm or 0.3mm.

In order to which finger is passed through into the first endoporus 11 and the second endoporus 41, the internal diameter of the bearing 3 is chosen as φ 10- 35mm.For example, the internal diameter of the bearing 3 is φ 17mm, φ 20mm, φ 25mm or φ 30mm.First endoporus 11 and the second endoporus 41 can pass through a finger most appropriate, be easy to hold, and improve recreational, and endoporus is too big or too small can influence using effect.

The size of several bearings 3 is listed in following table：

Wherein, the internal diameter of bearing is d, and bearing outside diameter D, the width of bearing is h, and unit is mm.

The device of the application is described in detail with reference to the optimal technical scheme of the application, however, it is necessary to explanation, not Depart from spirit herein in the case of, those skilled in the art can be made on the basis of above disclosure it is any transformation, Modification and variation.The application includes above-mentioned specific embodiment and its any equivalents.
