Technical Field

The utility model relates to the technical field of traditional sports or entertainment appliances, in particular to a bearing-free diabolo.

Background

The bearing-free diabolo has good stability while ensuring a high rotating speed, can finish certain actions with higher difficulty, and is suitable for diabolo beginners to use. The structure of the bearingless diabolo mainly comprises two diabolo bowl bodies and an axis connected between the two diabolo bowl bodies, the axis between the two diabolo bowl bodies is used for winding a diabolo rope, the two ends of the diabolo rope are connected with rods for a user to hold and control, and the diabolo rope is pulled up and down back and forth to drive the diabolo to rotate.

The most important thing for the rotation of the diabolos is balance, and the rotation of the diabolos can be accurately controlled only by enabling the gravity centers of two diabolo bowl bodies of the diabolos to be symmetrical and balanced and not to incline or skew. At present, two diabolo bowl bodies used by diabolos are mostly formed by injection molding of plastic materials, and the gravity center of the two bowl bodies is easy to shift due to the influence of cooling molding time in a mold in the injection molding process, so that the diabolo can not be balanced in rotation after being assembled, and the operation is difficult. In addition, the plastic diabolo bowl body is lighter and does not provide good rotational centrifugal force, resulting in a shorter diabolo rotation time.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further specifically described below by way of embodiments in combination with the accompanying drawings.

Example 1

A bearing-free diabolo is shown in figures 1-2 and comprises two bowl bodies 1 with outward openings and an axle center 2 arranged between the two bowl bodies 1, wherein the axle center 2 comprises winding seats 21 arranged at two ends of the axle center. In the embodiment, the outer side surfaces of the two bowl bodies 1 close to the axis 2 are respectively attached with the outer cover 3, and a winding space is formed between the two outer covers 3 at the periphery of the axis 2; the outer cover 3 is a curved surface matched with the outer side surface of the bowl body 1, and the projection shape of the outer cover 3 along the axial direction is a centrosymmetric figure, so that the center of gravity of the outer cover is coincident with the axis of the outer cover, preferably, the outer cover is circular.

In the structure, the shaft lever 22 is arranged in the shaft center 2 in a penetrating mode along the circumferential direction, the two ends of the shaft lever 22 are respectively provided with the external threads and the locking screw cap 23 matched with the threads, the centers of the bowl body 1 and the outer cover 3 are provided with the assembling holes for the shaft lever 22 to pass through, the shaft lever 22 sequentially passes through the bowl body 1, the outer cover 3, the shaft center 2, the outer cover 3 on the other side and the bowl body 1, then the fastening is carried out in the arc-shaped space 10 on the inner side of the bowl body 1 through the locking screw cap 23, and therefore all parts are fixed.

In this embodiment, the inner side of the outer cover 3 is concentrically provided with the accommodating ring groove 31, the accommodating ring groove 31 is embedded with the annular counterweight ring 32, the annular counterweight ring 32 can be made of hard plastics with high density or metal, and a proper amount of counterweight is added through the annular counterweight ring 32, so that a good rotation centrifugal force of the diabolos can be provided, and the rotation time of the diabolos is prolonged; and the arrangement of the annular counterweight ring 32 can dilute the offset of the gravity center of the bowl body, and the integral gravity center of the single bowl body 1, the outer cover 3 and the annular counterweight ring 32 is close to the middle position of the whole diabolo, so that the gravity center of the diabolo is corrected, and the diabolo is more stable and longer in time when rotating.

In addition, the surface of outer housing 3 sets up to smooth curved surface in this embodiment, because the surface of outer housing 3 is the position with the diabolo rope most often contact, sets up it into smooth curved surface and can reduce its and the friction of diabolo rope, and then reduces the influence of diabolo rope to the diabolo rotational speed.

Example 2

Referring to fig. 3-4, the present embodiment is different from embodiment 1 only in that the annular weight ring in embodiment 1 is disposed between the outer cover 3 and the bowl body 1, and the annular weight ring 32 in this embodiment is partially disposed between the outer cover 3 and the bowl body 1, and the rest is disposed outside the outer ring of the outer cover 3.

Specifically, the outer ring size of the outer cover 3 is slightly larger than the inner ring size of the annular weight ring 32, so that the outer edge of the outer cover 3 can support the inner ring edge of the annular weight ring 32 on the outer surface of the bowl body 1, thereby fixing the annular weight ring 32.

In this embodiment, the outer surface of the annular counterweight ring 32 is the most frequently contacted position with the diabolo rope, so the outer surface of the annular counterweight ring 32 is set to be a smooth curved surface in this embodiment, the friction between the annular counterweight ring and the diabolo rope is reduced, and the influence of the diabolo rope on the rotation speed of the diabolo is further reduced.

In addition, the color of the annular counterweight ring 32 is set to be different from the colors of the bowl body 1 and the outer cover 3 in the embodiment, so that the diabolo has layering sense and attractive appearance is improved. The present embodiment is not limited as to whether the bowl body 1 and the outer lid 3 are the same color.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. It is obvious that the utility model is not limited to the above-described embodiments, but that many variations are possible. Any simple modification and modification of the above embodiments in accordance with the technical spirit of the present invention should be considered as falling within the scope of the present invention.
