Abstract

Diabolo is a fitness and entertainment device that makes sounds when it rotates. It is mainly composed of two sound-generating wheels connected by an intermediate shaft. It is characterized in that the sound-generating wheels are circular and plum blossom-shaped, and there are more than two sound generators in the sound-generating wheel. The small sound generator is composed of a small partition with a circular arc or elliptical arc cross-section. A sound-generating port is provided on the outer edge of the sound-generating wheel and communicates with the small sound generator. The cross-sectional shape of the sound-generating port is parallel or trapezoidal.

Description

Diabolo

The utility model relates to the body-building recreation utensil that a kind of rotation gets up to send the sound.

Whistle of the prior art exists makes difficulty, and sealing is poor, shortcomings such as audio frequency dullness, and two side plates of existing Whistle are made with glued board, and small baffle adopts bamboo chip to make, and the assembling difficulty is yielding, and poorly sealed, causes to mix.

The purpose of this utility model is to design novel body-building recreation utensil one diabolo that a kind of overall structure can overcome above-mentioned shortcoming.

The purpose of this utility model is to realize like this, it is mainly by two sounding wheels, jackshaft connects to form, it is characterized in that taking place wheel is made up of wheel body and side cover plate, wheel body is circular or quincunx, be provided with more than two little acoustical generator and wheel body in the wheel body and make an integral body, little acoustical generator is to be that the small baffle of garden arc or elliptic arc forms by a cross sectional shape, sounding wheel wheel body outer rim is provided with the sounding mouth and communicates with little acoustical generator, the cross sectional shape of sounding mouth is parallel shape or trapezoidal shape, the sounding mouth is in a sounding wheel in addition, parallel shape is for arranging in the same way, trapezoidal shape can be in the same way, also can be not in the same way, and the sounding mouth of two sounding wheels can be in the same way, also can be not in the same way, to send different effects,sounds.

The utility model is made simple, the wheel wheel body takes place can pass through mould of plastics one-shot forming good seal performance, can send the melodious sound during use, is a kind of economical and practical desirable body-building recreation utensil.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1, overall structure schematic diagram of the present utility model.

Fig. 2, generation of the present utility model wheel wheel body schematic diagram.

Another embodiment schematic diagram of Fig. 3, generation of the present utility model wheel wheel body profile.

A mouthful schematic cross-section takes place in Fig. 4, the utility model.

Among the figure 1, take turns 2, jackshaft, 3, side cover plate, 4, wheel body, 5, small baffle (little generator), 6, take place mouthful.

Consult Fig. 1, Fig. 2, the utility model is taken turns (1) by two sounding, jackshaft (2) is formed, it is characterized in that taking turns (1) is made up of wheel body (4) and side cover plate (3), wheel body (4) can circular or quincunx (Fig. 2, Fig. 3), being provided with the little acoustical generator of little acoustical generator (5) (5) more than two in the wheel body (4) and being by a cross sectional shape is that the small baffle (5) of garden arc or elliptic arc forms, sounding wheel (1) wheel body (4) outer rim is provided with sounding mouth (6) and communicates with little acoustical generator (5), the cross sectional shape of sounding mouth (6) is parallel shape or trapezoidal shape, sounding mouth (6) is to arrange in the same way when a sounding is taken turns in (1) parallel shape in addition, can be in the same way during trapezoidal shape, also can be not in the same way, the sounding mouth (6) of two sounding wheels (1), can be in the same way, also can be not in the same way, to send different effects,sounds.

When practical, a rope two connects with club, rope is trembled diabolo jackshaft mid portion, with hand shake diabolo is turned over, along with the quickening sounding mouth of speed because wind action, sound simultaneously, since the difference of the number of little acoustical generator, the shape of sounding mouth, large and small difference, and the sound that sends is also different, be a kind ofly firmly get that public a kind of collection of liking are recreational, gymnastics, craftsmenship, flexibility, performance, the toy that has reserve value again simultaneously.

Claims (2)

1, a kind of rotation gets up to send the body-building recreation utensil-diabolo of the sound, mainly connect to form by two sounding wheels (1), jackshaft (2), it is characterized in that taking place wheel is made up of wheel body (4) and side cover plate (3), wheel body (4) is circular or quincunx, be provided with more than two little acoustical generator (5) and wheel body (4) in the wheel body (4) and make an integral body, little acoustical generator (5) is to be that the small baffle (5) of garden arc or elliptic arc forms by a cross sectional shape, and sounding wheel wheel body (4) outer rim is provided with sounding mouth (6) and communicates with little acoustical generator (5).

2, diabolo according to claim 1, it is characterized in that: the cross sectional shape of sounding mouth (6) is parallel shape or trapezoidal shape, parallel shape is for arranging in the same way in a sounding wheel (1), trapezoidal shape can be in the same way, also can be not in the same way, the sounding mouth (6) of two sounding wheels (1) can be in the same way, also can be not in the same way.
