Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of yo-yo bearing brackets, in particular to a double-material yo-yo bearing bracket. Background Art
[0002] As an extreme hand sports toy, yo-yo needs to be constantly served and collected during play, which is different from the diabolo which does not have the ability to recover the ball. Therefore, yo-yo is required to have appropriate recovery ability so that it can better respond to the player's dribbling action and give corresponding sports feedback.
[0003] The recovery effect of the yo-yo is achieved by using friction resistance as the recovery force, and the internal structure of the yo-yo consists of three parts, which also provide the recovery force. These three parts are: the recovery system on the yo-yo ball to increase the friction between the ball and the ball rope; the ball bearing that provides rotation resistance; and the bearing support that assists in increasing the friction between the yo-yo rope and the yo-yo. Generally speaking, the friction resistance between the bearing support and the ball rope is not the most influential factor, but since the aluminum alloy bearing support is manufactured by the lathe, it is also necessary to undergo a surface treatment process of coating and coloring to distinguish bearing supports of different sizes and models. Therefore, the friction between the bearing support and the ball rope will also be affected by the accuracy of the surface treatment, the coating material used for the surface treatment, and the coating thickness. In the actual production process, the thickness of the surface coating cannot be guaranteed to be exactly the same for each batch. Even the surface coating of the same batch of bearing supports may vary greatly due to production errors and process precision. Therefore, in order to obtain yo-yo bearing supports that suit their own feel preferences, players can only grind the bearing supports themselves or purchase a large number of bearing supports and screen them themselves. In this process, the bearing supports are often scrapped due to manual operation errors, or a large amount of financial resources are consumed, resulting in great waste and losses.
[0004] Therefore, a yo-yo bearing holder composed of two materials is proposed. Utility Model Content
[0005] The utility model aims to provide a dual-material yo-yo bearing support to solve the above-mentioned background technical problems.
[0006] In order to achieve the above object, the utility model provides the following technical solution: a dual-material yo-yo bearing support, comprising: an outer ring, a mounting cavity is formed on one side of the outer ring, and a through hole is formed on one side of the mounting cavity;
[0007] The inner sill is inserted into the installation cavity, a chamfered portion is fixedly connected to one side of the inner sill, and an inserting portion is fixedly connected to the opposite side of the inner sill.
[0008] Preferably, there is an interference fit between the inner rim and the mounting cavity.
[0009] Preferably, the inner sill is made of aluminum alloy material.
[0010] Preferably, the outer ring is made of plastic material.
[0011] Preferably, a mounting hole is provided on the inner sill, and the inner diameter of the mounting hole is matched with the outer diameter of the yo-yo central axis screw.
[0012] Preferably, the outer diameter of the inserting portion matches the inner diameter of the through hole.
[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0014] The yo-yo bearing support is manufactured by combining a plastic outer liner with an aluminum alloy inner sill. By selecting materials of different colors and types for lathe processing, a bearing support outer ring with extremely high precision composed of multiple colors can be directly obtained without the need for surface treatment coating. The internal aluminum alloy inner sill is turned out of aluminum alloy material and chamfered at the top so that it can be smoothly installed in the plastic bearing support outer ring and connected with the inner sill by interference fit to ensure its combined strength and prevent displacement or falling off during use. Accessories of different sizes are designed for it to have higher precision, more size combinations and better feel. The bearing support size data can be changed through different assembly methods, so that it has a wider range of applications and changes the recovery performance of the yo-yo.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] The utility model provides Figure 1-Figure 3 A dual-material yo-yo bearing support shown in the figure includes: an outer ring 1, a mounting cavity 2 is opened on one side of the outer ring 1, and a through hole 6 is opened on one side of the mounting cavity 2; an inner rim 3, the inner rim 3 is inserted into the mounting cavity 2, a chamfered portion 4 is fixedly connected to one side of the inner rim 3, and an inserting portion 5 is fixedly connected to the opposite side of the inner rim 3, the mounting cavity 2 is used for positioning and inserting the inner rim 3, and the through hole 6 is used for accommodating the inserting portion 5, so as to facilitate the installation of the bearing on the yo-yo.
[0023] Furthermore, there is an interference fit between the inner rim 3 and the mounting cavity 2, and the interference fit can ensure the combined strength thereof and will not be displaced or fall off during use.
[0024] Furthermore, the inner rim 3 is made of aluminum alloy material, and the aluminum alloy inner rim 3 also has a variety of sizes, which is mainly reflected in its radial height. For a wide-spacing basic entry-level yo-yo that requires more online space and idling time, a high-height aluminum alloy inner rim 3 can be used to widen the ball and improve the idling ability of the yo-yo; for a narrow-spacing spinning fancy yo-yo that requires a highly sensitive recovery effect, a medium-height aluminum alloy inner rim 3 can be used to make the ball spacing and the thickness of the ball rope perfectly matched, while maintaining the yo-yo's ideal idling ability. The recovery ability can also be improved; for some spinning fancy yo-yos with fixed spacing that have a clearance inside the bearing support and can move a small amount laterally on the central axis, the shortest aluminum alloy inner rim 3 can be used so that after assembly, whether it is the front or back of the bearing support, the two surfaces of the aluminum alloy inner rim 3 are flush with the outer lining of the plastic bearing support, thereby providing the clearance required by the yo-yo.
[0025] Furthermore, the outer ring 1 is made of plastic material, specifically PVC, ABS, POM and other plastic materials. By selecting materials of different colors and types for lathe processing, a bearing support outer ring 1 with extremely high precision composed of multiple colors can be directly obtained without the need for surface treatment coating. Another advantage of the bearing support outer ring 1 being made of plastic material is that compared with metal bearing supports, plastic material can provide greater friction, so that the yo-yo has a crisper feel when doing spinning fancy plays.
[0026] Furthermore, a mounting hole 7 is provided on the inner rim 3 , and the inner diameter of the mounting hole 7 is matched with the outer diameter of the yo-yo center axis screw. The mounting hole 7 is used to facilitate the matching installation of the inner rim 3 and the yo-yo center axis screw.
[0027] Furthermore, the outer diameter of the inserting portion 5 is matched with the inner diameter of the through hole 6 , and the through hole 6 is used to accommodate the inserting portion 5 , so as to facilitate the connection and fixation between the inner rim 3 and the outer ring 1 .
[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
