Description
Technical field
The utility model relates to a kind of Climbing top Yo-Yo, the Climbing top Yo-Yo of specifically a kind of numerical control turning making.
Background technology
Climbing top Yo-Yo firmly gets the games for play that many children like, the basic structure of existing Climbing top Yo-Yo is include two rotary bodies, connect the connecting axle of two rotary bodies and be wrapped in the long rope on the middle bearing be nested with of connecting axle, rotary body is provided with connector be connected with connecting axle, due to existing Climbing top Yo-Yo substantially all by Making mold out, therefore be all generally that a rotary body and connector are injection molded into one, another rotary body and connecting axle are injection molded into one, then screw in connector by connecting axle and realize two rotary bodies connections and be assembled into Climbing top Yo-Yo.Usually when injection moulding, connector or connecting axle may move in the rotary body also not solidifying sizing, thus the accuracy causing connector to locate reduces, and its circularity of the rotary body of injection moulding also has some deviations, causes the distribution of weight of spheroid uneven.These all can cause final Climbing top Yo-Yo unstable when rotated above, can produce and rock.
Summary of the invention
The purpose of this utility model is to solve above-mentioned existing problems, provides one to be connected firmly, the Climbing top Yo-Yo that the numerical control turning effectively improving the performance of Climbing top Yo-Yo makes.
The technical solution of the utility model is achieved in that
The Climbing top Yo-Yo that a kind of numerical control turning makes, comprise two rotary bodies and connect the connecting axle of two rotary bodies, the lateral surface of described rotary body is provided with the plate-like concave surface caved inward, be characterized in that the plate-like concave surface of described rotary body is middle and be provided with connecting hole, in described connecting hole, connector is installed, the back side of described connector is extended with projection, the end of described projection inwardly has screwed hole, described connecting axle correspondence is designed to thread spindle, is screwed in respectively in the screwed hole of the connector on two rotary bodies and be assembled into Climbing top Yo-Yo by the two ends of connecting axle.
In order to improve precision to improve the performance of Climbing top Yo-Yo further, described rotary body is the circular disk body made by numerical control turning, and this rotary body can be that plastics are made, and also can be that metal is made.
Further, because rotary body is that turning process is made, so described connector by the mode of machine pusher, can only utilize some elasticity that plastic cement is intrinsic, is fitted in described connecting hole by connector.
Further in order to improve the fastness of connection, the interface of described connector and connecting hole is provided with a circle wedge shape fin, the diameter that described wedge shape fin surrounds is greater than the aperture of connecting hole, to be fitted in described connecting hole by connector wedge shape fin to be closely cooperated with the limit wall of connecting hole and realizes connector to be firmly connected with rotary body by machine pusher mode.
The utility model also includes base bearing, and described base bearing is socketed on the projection of described two connectors, is spun and realize base bearing being limited to rotationally the position in the middle of two rotary bodies by the screwed hole of connecting axle and two projections.
The utility model is due to the plate-like concave surface centre all installation connecting elements at two rotary bodies, screwed hole is provided with at the back side of connector, connecting axle is designed to thread spindle spin with two screwed holes respectively and be assembled into Climbing top Yo-Yo simultaneously, thus make the gravity balance of Climbing top Yo-Yo, improve the smooth rotation of Climbing top Yo-Yo, and connector by machine pusher on rotary body, therefore combine firmly, effectively improve the precision of assembling; Again because rotary body adopts turning process, therefore can ensure that this rotary body is for positive circular, and distribution of weight is even, accuracy is high, further improve the performance of Climbing top Yo-Yo, major embodiment stability when rotated, two rotary bodies are almost rotate along same axis, can not off-axis and producing shake dynamic.
Below in conjunction with accompanying drawing, the utility model is further described.
