Abstract

The utility model relates to an entertainment and exercise instrument. The purpose of the utility model is to provide a design structure which can idle for some time in situ and can be wound and retracted after a yo-yo is quickly thrown out. The utility model simultaneously has an acoustic-optic effect to increase the amusement, which is suitable for the requirement of a primary player. To realize the purpose, the utility model is composed of a first body, a second body, a circuit board, a rope, a spring piece, a braking piece on the spring piece, a rotating shaft, etc. The centrifugal force thrown out by a player causes the braking piece to disengage from the control for the rotating shaft. When the rotating speed of the bodies drops, the spring piece controls the rotating shaft again, and the acoustic-optic effect is increased through voice and the refraction of light emitting diodes and a cover plate.

Description

A kind of yo-yo structure

The utility model belongs to the double apparatus of taking exercise of a kind of amusement.

Traditional yo-yo is formed a complete body with two independently symmetrical bodies, between two bodies, be provided with a rotating shaft, these rotating shaft central authorities establish a central shaft again, rotating shaft is provided with a rope, during recreation, with rope with the relaxed state rotating shaft of reeling, then yo-yo is thrown away, can spur and drive rotating shaft and body rotation by the tangent line of rope along rotating shaft, throw away to the utmost point at body that moment spurs rope fast in limited time, inertia in the time of can being rotated by body is reeled rope toward rightabout, throw away backward again, back and forth carries out.With the effect that reaches recreation and take exercise.In the fancy recreation of yo-yo, wherein one is at once rope not to be retracted fast after yo-yo is thrown away fast, but allow yo-yo throw away the limit original position idle running of back fully at rope, treat that moment retracts rope fast again after a period of time, so that the rope overline is wound in the rotating shaft, but this kind skill must be practised a segment length can be skilled after the time, can not satisfy player's requirement just.

The purpose of this utility model provides a kind of project organization that can reel and reclaim in original place idle running a period of time after yo-yo throw away fast, it is recreational to increase to have sound and light program simultaneously concurrently, is fit to common player's needs just.

The utility model is provided with the brake block that plural number is incorporated into spring leaf in the body of yo-yo, so that yo-yo utilizes centrifugal force that brake block is removed when rotating at a high speed, the rotating shaft that is located in yo-yo is not in original place idle running and with the rope backrush, and when the rotating speed of yo-yo reduces, then each brake block is pressed from both sides simultaneously and pull in rotating shaft by the elastic force of spring leaf, and then automatically make rotating shaft that rope is reeled again, do the difficulty of this grandstand play with reduction.

Be provided with circuit board in the yo-yo body, and be provided with light and voice IC device in this circuit board, cooperate the yo-yo made from transparent material to have sound and light program when recreation, the said structure design has realized the purpose of this utility model.

The utility model has the advantages that: first player just can finish and throw away back auto reeling recovery again after idle running a period of time in the original place fast, when amusement, has sound and light program, and be provided with polygonal water chestnut face at the inner surface of yo-yo, make the light that is sent to do the multi-angle refraction via polygonal water chestnut face, make light dazzling more brilliant, increased recreationally, thrown repeatedly and get rid of also and can effectively take exercises, reached body-building effect.

The utility model is described in further detail below in conjunction with accompanying drawing.
