Description

RELATED APPLICATIONS

[0001] The present patent document claims the benefit of priority to Patent Application No. 202520726982.6, filed Apr. 17, 2025, and entitled “NEW TYPE OF YO-YO,” the entire contents of each of which are incorporated herein by reference.BACKGROUND1. Technical Field

[0002] The present invention relates to the field of toys, in particular to a new type of yo-yo.2. Background Information

[0003] Currently, a toy product of a yo-yo combined with a fingertip spinning top on the market has an issue in the structure for achieving independent rotation of the fingertip spinning top, where a cover can be fixed but cannot be easily disassembled, making it difficult to replace a bearing. This results in poor playability and lack of diversity in the toy. To address this, a new type of yo-yo is proposed.BRIEF SUMMARY

[0004] The present invention aims to provide a technical solution that overcomes the above shortcomings and addresses the above issues.

[0005] The present invention discloses a new type of yo-yo, including at least one set of yo-yo bodies, where a spinning top cover is disposed on a side of the yo-yo body, a boss is disposed between the spinning top cover and the yo-yo body, the boss is formed at a middle position inside the yo-yo body, a fixing screw is transversely inserted inside the boss, a spinning top bearing sleeves the fixing screw, the spinning top bearing is located inside the boss, a fixed bearing nut is disposed between the spinning top bearing and the boss, the fixed bearing nut is threadedly connected to the boss, and the fixed bearing nut is fixed on the boss.

[0006] Preferably, a yo-yo body connecting shaft is disposed between the yo-yo bodies, the yo-yo body connecting shaft is transversely spanned between the yo-yo bodies, and two ends of the yo-yo body connecting shaft are each inserted into another outer side of the yo-yo body.

[0007] Preferably, the yo-yo body connecting shaft is provided with a yo-yo body bearing, the yo-yo body bearing sleeves the yo-yo body connecting shaft, and the yo-yo body connecting shaft rotates at a middle position of the yo-yo body bearing.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The fixed bearing nut can secure the spinning top bearing and the fixing screw inside the boss. The fixing screw passes through the fixed bearing nut and the fixing screw is threadedly connected to the spinning top cover. One side of the spinning top cover is inserted between the spinning top bearing, thereby allowing one side of the spinning top cover to be mounted on the boss via the fixing screw and enabling the spinning top cover to rotate relative to the yo-yo body via the spinning top bearing. Additionally, by means of turning the fixing screw and the fixed bearing nut, the spinning top cover can be detached from the yo-yo body, and the spinning top bearing can be removed from the interior of the boss for replacement, thus enhancing the playability and diversity of the yo-yo body.

[0009] Additional aspects and advantages of the present invention will be partially provided in the following description, will become apparent from the following description, or will be understood through the practice of the present invention.BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following description will clearly and comprehensively present the technical solutions in the embodiments of the present invention with reference to the accompanying drawings. It is evident that the described embodiments represent only some, but not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort fall within the scope of protection of the present invention.

[0020] Referring to FIGS. 1 to 7, in the embodiments of the present invention, a new type of yo-yo is provided, including at least one set of yo-yo bodies 1. A spinning top cover 2 is disposed on a side of the yo-yo body 1, and a boss 5 is disposed between the spinning top cover 2 and the yo-yo body 1. The boss 5 is formed at a middle position inside the yo-yo body 1. A fixing screw 7 is transversely inserted inside the boss 5, and a spinning top bearing 8 sleeves the fixing screw 7. The spinning top bearing 8 is located inside the boss 5, and a fixed bearing nut 6 is disposed between the spinning top bearing 8 and the boss 5. The fixed bearing nut 6 is threadedly connected to the boss 5, and the fixed bearing nut 6 is fixed on the boss 5, thereby allowing the spinning top bearing 8 and the fixing screw 7 to be secured inside the boss 5 via the fixed bearing nut 6. The fixing screw 7 passes through the fixed bearing nut 6 and the fixing screw 7 is threadedly connected to the spinning top cover 2. One side of the spinning top cover 2 is inserted between the spinning top bearing 8, thereby allowing one side of the spinning top cover 2 to be mounted on the boss 5 via the fixing screw 7 and enabling the spinning top cover 2 to rotate relative to the yo-yo body 1 via the spinning top bearing 8. Additionally, by means of turning the fixing screw 7 and the fixed bearing nut 6, the spinning top cover 2 can be detached from the yo-yo body 1, and the spinning top bearing 8 can be removed from the interior of the boss 5 for replacement, thus enhancing the playability and diversity of the yo-yo body 1. Before the spinning top cover 2 is detached from the yo-yo body 1, the yo-yo body 1 is first rotated and disassembled using a disassembly tool such as a screwdriver, the yo-yo body connecting shaft 3 is disassembled, and the screwdriver is inserted through the hole of the yo-yo body connecting shaft 3 to turn the fixing screw 7, thereby achieving the detachment of the spinning top cover.

[0021] A yo-yo body connecting shaft 3 is disposed between the yo-yo bodies 1, and the yo-yo body connecting shaft 3 is transversely spanned between the yo-yo bodies 1. Two ends of the yo-yo body connecting shaft 3 are each inserted into another outer side of the yo-yo body 1, thereby allowing at least one set of yo-yo bodies 1 to be assembled and connected via the yo-yo body connecting shaft 3.

[0022] The yo-yo body connecting shaft 3 is provided with a yo-yo body bearing 4, the yo-yo body bearing 4 sleeves the yo-yo body connecting shaft 3, and the yo-yo body connecting shaft 3 rotates at a middle position of the yo-yo body bearing 4, thereby allowing a rope (not shown in the figure) along with a spool (not shown in the figure) to sleeve the yo-yo body connecting shaft 3 via the yo-yo body bearing 4. This enables the operator to hold one end of the rope, throw the yo-yo body 1, and produce a “hovering effect” at the lowest point, providing a time window for performing tricks. At this moment, the yo-yo body connecting shaft 3 continues to rotate without winding the rope.

[0023] For those skilled in the art, it is apparent that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any perspective, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims within the present invention.
