As a kind of improvement of the present utility model, the quantity of the eccentric orfice is two, and it is symmetricly set on centre bore Two side positions.

As a kind of improvement of the present utility model, the appearance profile of the eccentric orfice is circle.

As a kind of improvement of the present utility model, ball is equipped with the upper surface of the upper press cover and the lower surface of lower cover Face is recessed.

As a kind of improvement of the present utility model, circular groove is equipped with the upper and lower surface of the chain wheel.

The beneficial effects of the utility model are：The utility model smart structural design, chain wheel structure rationally is used, and in tooth Chain is wound with disk, not only modern design, good appearance, and also total quality is big, and inertia is big so that and rotation is more lasting, Stability is more preferable, and upper and lower gland is engaged by bearing with chain wheel, and frictional force is small, rotate it is flexible, rotary speed faster, The further persistence and stability of lifting rotation, greatly improves the playability and interest of toy, and then improves player Interest, it can in addition contain take chain apart, chain wheel rotation is torn in a manner of draw chain, force is bigger, and explosive force is stronger, more can Rotary speed is lifted, fado is played, meets different demands of playing, more enjoyment, recreational height are provided for player.

Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.

Brief description of the drawings

Fig. 1 is dimensional structure diagram of the present utility model.

Fig. 2 is decomposition texture schematic diagram of the present utility model.

Embodiment

Referring to Fig. 1 and Fig. 2, the present embodiment provide a kind of chain finger tip gyro, it include chain wheel 1, chain 2, bearing 3, Upper press cover 4 and lower cover 5, the chain 2 are wrapped on the outer peripheral face of chain wheel 1, and the center of the chain wheel 1 is provided with and the axle 3 centre bores 11 being adapted are held, the bearing 3 is arranged on the centre bore 11, and the upper surface centre bit of the lower cover 5 installs There is the adapter sleeve 51 that the inner ring with the bearing 3 is adapted, the adapter sleeve 51 is plugged in the inner ring of bearing 3, the adapter sleeve 51 Inwall be provided with internal thread, the upper press cover 4 is provided with the connecting pole 41 being adapted with the adapter sleeve 51, the connecting pole 41 Outer surface be provided with the external screw thread that is adapted with the internal thread, the chain wheel 1 is provided with and is eccentrically provided with an eccentric orfice 12.This reality Apply in example, the quantity of the eccentric orfice 12 is two, and it is symmetricly set on two side positions of centre bore 11.Eccentric orfice 12 is rotating During, annular transparent cell can be formed, good appearance is interesting strong.In the present embodiment, the appearance profile of the eccentric orfice 12 It is easy to process for circle, and good appearance.In other embodiments, the appearance profile of the eccentric orfice 12 can also be square or it Its shape.

Preferably, adapter sleeve 51 peripheral position be provided with can be on inner ring lower surface of the top pressure in bearing 3 lower convex platform 52. The convex platform being provided with the peripheral position of connecting pole 41 on inner ring upper surface of the energy top pressure in bearing 3.So that upper press cover 4 and pushing More close, the good connecting effect that lid 5 coordinates with bearing 3.

Preferably, being equipped with spherical depression on the upper surface of the upper press cover 4 and the lower surface of lower cover 5, meet human body Engineering science, comfortableness when lifting is played.

Circular groove 13, more aesthetic property are equipped with the upper and lower surface of the chain wheel 1.

When playing, because the utility model chain finger tip gyro uses chain wheel structure, and chain 2 is wound with chain wheel 1, Not only modern design, good appearance, and also total quality is big, and inertia is big so that and rotation is more lasting, and stability is more preferable, and Upper press cover 4, lower cover 5 are engaged by bearing 3 with chain wheel 1, and frictional force is small, are rotated flexibly, rotary speed faster, further carries The persistence and stability of rotation are risen, greatly improves the playability and interest of toy, and then improves the interest of player, in addition Chain can also be taken apart, chain wheel rotation is torn in a manner of draw chain, force is bigger, and explosive force is stronger, can more lift rotation Speed, fado is played, more enjoyment are provided for player.

The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned realities The mode of applying is changed and changed.Therefore, the utility model is not limited to above-mentioned embodiment, every this area skill It is new that art personnel any conspicuously improved, replacement or modification made on the basis of the utility model belong to this practicality The protection domain of type.In addition, although used some specific terms in this specification, but these terms are intended merely to conveniently say It is bright, any restrictions are not formed to the utility model.As described in the utility model above-described embodiment, using same or similar Structure obtained from other structures toy, in scope of protection of the utility model.
