DETAILED DESCRIPTION
[0021] As shown in FIG. 1 to FIG. 5, a tornado yoyo is provided, and includes two rotating disks 1 and a connecting axle 2 configured to connect back portions of the two rotating disks 1. A protruding cylinder 11 provided with a bearing 4 thereon is disposed within the rotating disk 1 and located in the middle of the rotating disk 1. A rotating cap 3 is disposed outside the rotating disk 1 and covers the rotating disk 1, the rotating cap 3 is provided with a connecting hole portion 31 extending from the middle of the rotating cap 3 to the rotating disk 1, and the connecting hole portion 31 is sleeved on the bearing 4 to realize a rotation of the rotating cap 3 relative to the rotating disk 1. An outer edge of the rotating cap 3 is provided with an edgefold 32 configured to envelop an edge of the rotating disk 1, so that when the yo-yo is held or pinched in a forward direction, fingers contact the edgefold 32 of the rotating cap 3, and therefore the rotation of the rotating disk 1 will not be influenced. As a result, more on-hand operation manners are provided compared with the yo-yo in the prior art, and in cooperation with an operation of a string, more new style fancy motions can be realized by combination or creation, thus meeting a requirement of a yo-yo hobbyist for exploring and creating a new trick of yo-yo.
Embodiment One
[0022] As shown in FIG. 1 to FIG. 3, a space defined by the edgefold 32 and the edge of the rotating cap 3 is larger than a disk edge 12 of the rotating disk 1 in the present embodiment, so a gap exists between the edgefold 32 and the disk edge 12 of the rotating disk 1 when the rotating cap 3 is connected with the bearing 4, thus preventing the rotating cap 3 from contacting the rotating disk 1 and influencing the rotation of the rotating disk 1. In the present embodiment, an outer surface of the rotating cap 3 is configured as an evenly concave surface, the concave surface is high at edge and low in middle, and a center of the rotating cap 3 is a lowest part of the concave surface. The connecting hole portion 31 of the rotating cap 3 is located on a bottom surface of the rotating cap 3, and a hole wall of the connecting hole portion 31 is molded integrally with the rotating cap 3. The concave surface configured in such a manner may be used by a player to make a finger grind trick, thus further adding playing methods of the yo-yo. In the present embodiment, the protruding cylinder 11 is provided with a circle of groove 13 close to an end thereof, and when the bearing 4 is sleeved on the protruding cylinder 11, the groove 13 extends out of the bearing 4, such that the bearing 4 is connected with the protruding cylinder 11 via a retaining ring 5 fitted in the groove 13. This kind of fixing method is simple and practical. In the present embodiment, the retaining ring 5 is configured as an O-shaped rubber retaining ring, and the groove 13 is configured as a semicircle groove correspondingly. After the O-shaped rubber retaining ring 5 is fitted in the semicircle shaped groove 13, a half of the retaining ring 5 is projected out of the groove 13, so as to prevent the bearing 4 from leaving off the protruding cylinder 11, thus having an effect of stopping and position limiting. If the rotating cap 3 needs to be detached, as the O-shaped rubber retaining ring 5 has good elasticity, it is only needed to hardly pull the rotating cap 3 outwards, so as to make the bearing 4 squeeze the O-shaped rubber retaining ring 5 and thus to allow the O-shaped rubber retaining ring 5 to go through an internal diameter of the bearing 4, and thereby, the rotating cap 3 can be detached. Therefore, assembling and disassembling of the rotating cap 3 are convenient and efficient, and rotating caps 3 having different shapes can be changed as needed. In the present embodiment, the disk edge 12 of the rotating disk 1 is provided with a ring groove 15 in the middle of an end surface thereof, and a counter weight ring 7 is fitted in the ring groove 15, so that a gravity center of the rotating disk 1 moves outwards, and therefore the yo-yo is more stable when rotating. The rotating disk 1 is provided with a circular plate 8 therein, the circular plate 8 has a circular hole 81 in the middle thereof and is sleeved on the protruding cylinder 11 of the rotating disk 1 through the circular hole 81, and an outer surface of the circular plate 8 is provided with a layer of ornamental lines or patterns, or a hobbyist may stick or draw a pattern he or she likes on the outer surface of the circular plate 8, so that the yo-yo is more aesthetic and distinctive. Further, in order to observe the pattern in the circular plate 8, the rotating cap 3 may be configured as a transparent cap body correspondingly.
Embodiment Two
[0023] As shown in FIG. 4, general structures of the present embodiment are identical with those of Embodiment One, while a difference therebetween is that, in the present embodiment, a connecting block is connected to the middle of the rotating disk 1, the connecting axle 2 is connected with the connecting block and the protruding cylinder 11 is also provided on the connecting block. In the present embodiment, although the rotating cap 3 is configured as a disk-shaped body having an elevated edge, the rotating cap 3 is also arched up in the middle. An end of the protruding cylinder 11 is provided with a screw hole 14, and after the bearing 4 is sleeved on the protruding cylinder 11, a screw 6 is screwed into the screw hole 14 to realize a connection between the bearing 4 and the protruding cylinder 11, in which the screw 6 has a nut whose diameter is larger than that of the protruding cylinder 11. This kind of fixing method is also simple and practical, and the bearing 4 can be prevented from leaving off the protruding cylinder 11 by the nut, thus providing an effect of stopping and position limiting. If the bearing 4 needs to be taken out, the rotating cap 3 is pulled out firstly, then the screw 6 is screwed out, and lastly the bearing 4 is taken out. In the present embodiment, the rotating disk 1 is provided with a counter weight ring 9 therein, and the counter weight ring 9 is fixed with the rotating disk 1 through a twist-on screw. The hobbyist can stick or draw a pattern he or she likes on an arched-up circular surface of the rotating cap 3, so as to make the yo-yo more aesthetic and distinctive.
Embodiment Three
[0024] As shown in FIG. 5, general structures of the present embodiment are identical with those of Embodiment One, while a difference therebetween is that, in the present embodiment, a connecting block is connected to the middle of the rotating disk 1, the connecting axle 2 is connected with the connecting block and the protruding cylinder 11 is also provided on the connecting block. A protruding axle 33 configured to be held by a player or be plucked by a yo-yo string protrudes outwards from the middle of an outer surface of the rotating cap 3. With such a design, when the player plays the yo-yo, he or she can not only hold the edge of the rotating cap 3 by hands, but also pinch the two protruding axles 33 by fingers, so as to allow the yo-yo to continue rotating, and furthermore, the player can also pluck the protruding axle 33 via the yo-yo string to allow the rotating yo-yo to flip. In the present embodiment, the rotating disk 1 is provided with a counter weight ring 9 therein, and the counter weight ring 9 is provided with a snap edge configured to be fastened with a snap groove formed correspondingly in the rotating disk 1, so as to be fixed.
[0025] The present disclosure is described referring to specific embodiments, but the descriptions are not intended to limit the present disclosure. Referring to the descriptions of the present disclosure, other modifications of the disclosed embodiments are predictable to those skilled in the related art, and should belong to the scope defined by the claims.
