Description

Climbing top Yo-Yo

Technical field

The utility model belongs to a kind of toy, is specifically related to a kind of Climbing top Yo-Yo toy.

Background technology

Climbing top Yo-Yo comprises two rotary bodies and the connecting axle that is connected two rotary bodies.Climbing top Yo-Yo has multiple object for appreciation and plays tricks; difference play grandstand play to the quality of Climbing top Yo-Yo, be used to swing, physical property such as coefficient of friction (referring to coefficient of friction between the medial surface of rope and rotary body) has different requirements, the player of all ages and classes, different consummate degree also has different requirements to the above-mentioned physical property of Climbing top Yo-Yo in addition.Traditional Climbing top Yo-Yo is after dispatching from the factory, and global shape is difficult to change, and physical property also is difficult to regulate change, and lacks the interest of being assembled voluntarily by teenager's player.

In recent years, have the Climbing top Yo-Yo that to assemble voluntarily by teenager's player on the market, the rotary body of this each side of class Climbing top Yo-Yo all is provided with the rotating disk more than two, wherein the rotating disk near the Climbing top Yo-Yo center is called inner rotary table, rotating disk away from the Climbing top Yo-Yo center is called outer rotary table, can be bolted together between inner rotary table and the outer rotary table, also can take apart, realize the function that to reequip, can change thus.But still there is the following part that haves much room for improvement in they: one, package assembly complexity, and what have also needs to be applied to the gadget of losing easily, screw etc. for example, Assembly part quantity is many; Two, the existing Climbing top Yo-Yo of assembling voluntarily mostly can only be changed the outer rotary table of rotary body, and can not change the inner rotary table of rotary body; Three, for same Climbing top Yo-Yo, can only regulate weight separately, or can only regulate the change coefficient of friction separately; Four, regulate the complex structure that changes coefficient of friction.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of Climbing top Yo-Yo is provided, and it can be by the teenager as required or hobby repacking voluntarily, and package assembly is simple, and whole spare and accessory parts quantity is few.

Its purpose can realize by following scheme: two rotary bodies and the connecting axle that connects two rotary bodies about this Climbing top Yo-Yo comprises, each rotary body comprises outer rotary table, inner rotary table, inner rotary table is installed in the inboard of outer rotary table, inner rotary table central authorities are provided with circular hole, its main feature is, described connecting axle is a screw rod, one end of screw rod is fixedlyed connected with the outer rotary table of one of them rotary body, outer rotary table center at another rotary body is provided with screw, and the other end of screw rod is spirally connected with the rotary body outer rotary table that is provided with screw; The outer rotary table central part of each rotary body protrudes to the inside and is formed with the first boss platform, and the diameter of the outer rotary table first boss platform is equivalent to the diameter of inner rotary table central circular hole, and the first boss platform of outer rotary table is embedded in the circular hole of inner rotary table tightly.

Be preferably, the thickness that the first boss platform convex goes out is less than the thickness of inner rotary table central circular hole hole wall;

The boss platform central authorities of outer rotary table also protrude to the inside again and form the second boss platform, and the diameter of the second boss platform is less than the diameter of the first boss platform; Be formed with the annular gap between the inner rotary table central circular hole hole wall and the second boss platform, in the annular gap, be folded with ring apron.

Be more preferably, also interlocking tightly has annular balancing weight at the edge of the outer rotary table of each rotary body.

The utlity model has following advantage and effect:

1, Climbing top Yo-Yo product of the present utility model can be equipped with the standby ring apron of the standby inner rotary table of some different size weight, standby annular balancing weight and different coefficients of friction by producer in the product that dispatches from the factory; In use, can select suitable inner rotary table voluntarily for use by teenager's player; At any time assembling or repacking voluntarily is to adjust the weight of whole Climbing top Yo-Yo; In addition, can also use different standby ring aprons to reequip, thereby adjust the coefficient of friction of Climbing top Yo-Yo, the different objects for appreciation of adaptation are played tricks, the needs of different player.

2, an end of screw rod is affixed and the other end and another outer rotary table spin with an outer rotary table wherein, the then direct and unofficial biography dish interlocking of inner rotary table, ring apron then is folded between inner rotary table and the outer rotary table dexterously, therefore whole Climbing top Yo-Yo syndeton is simple, number of spare parts is few, renewal part simple to operate; In the operating process of changing, need not relate to the finding of losing easily, do not lose the anxiety of finding.In addition, in the operating process of whole repacking, need not make use of instruments such as screwdriver, can reequip voluntarily whenever and wherever possible.
