Description

Technical Field

[0001] The utility model relates to the technical field of yo-yos, in particular to a drum-shaped yo-yo equipped with a detachable weight ring. Background Art

[0002] Yo-yo is an extreme hand sport with various ways to play. One of the ways is called 2A, which stands for two-handed spinning. It means: holding a yo-yo in each hand, and completing various complex and highly ornamental yo-yo tricks by continuously releasing and recovering the two yo-yos, and winding and unwinding the lines between one yo-yo, the arm and the other yo-yo. In order to perform these tricks, players often choose a yo-yo with bulging sides (referred to as a drum yo-yo) for practice and performance. Common drum yo-yos usually only have 2A gameplay functions or basic entry-level gameplay functions, because the drum yo-yos used in the two gameplays have large differences in weight distribution, and even players who are good at 2A gameplay will have different requirements for the weight distribution of yo-yos due to their different preferences for feel.

[0003] At present, the mainstream 2A Yo-Yo for domestic and foreign gameplay has evolved from the drum-shaped Yo-Yo for basic entry-level gameplay, so it has the same structure as the drum-shaped Yo-Yo for basic entry-level gameplay, that is, it consists of a sphere, a ball cover, a central axis, a bearing support, a nut, a bearing and a gasket. Due to the single structure of the sphere, in the past, players could only modify the performance of the drum-shaped Yo-Yo by grinding the parts of the drum-shaped Yo-Yo or adding weights inside. These modified accessories are usually obtained by grinding, cutting and even heating and plasticizing various daily items collected by players in life, or by players contacting manufacturers for customization. This kind of spontaneous modification behavior of players can often only be carried out by experienced old players, because the trial and error cost and the customization cost of special accessories required for this modification are very high, and the success rate of modification is also very low, so it is not very ideal.

[0004] Therefore, a drum-type yo-yo ball whose performance can be changed by assembling and disassembling the weight ring is in urgent need of research. Utility Model Content

[0005] The utility model aims to provide a drum-shaped yo-yo equipped with a detachable weight ring to solve the above-mentioned shortcomings in the technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a drum-shaped yo-yo equipped with a detachable weight ring, comprising two spheres, the two spheres are detachably connected via a central axis, a ball cover is installed on the outer wall of the sphere, and a weight ring is detachably provided inside the sphere.

[0007] Preferably, a boss is integrally formed in the middle of the inner part of the sphere, a nut groove for installing a nut is opened axially at one end of the boss close to the ball cover, and a central axis groove for passing through the central axis is opened axially of the boss, and the central axis is screwed and connected to the nut groove.

[0008] Preferably, the counterweight ring is a plastic counterweight ring.

[0009] Preferably, the counterweight ring is an aluminum alloy counterweight ring.

[0010] Preferably, the counterweight ring is a composite counterweight ring formed by stacking aluminum alloy and plastic.

[0011] Preferably, the counterweight ring is made of POM material.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] The utility model can replace weight rings of different materials. By replacing the weight ring inside the yo-yo ball, the weight distribution inside the yo-yo can be changed to adapt to the operation feel and play requirements of more players, and daily play and performance are also more handy. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present utility model. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0020] 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.

[0021] The utility model provides Figure 1-3The drum-shaped yo-yo with a detachable weight ring shown comprises two spheres 1, which are detachably connected via a central axis, a ball cover 3 is installed on the outer wall of the sphere 1, and a weight ring 2 is detachably provided inside the sphere 1.

[0022] A convex seat 4 is integrally formed in the middle of the sphere 1 , and a nut groove 5 for installing a nut is formed in the axial direction of the convex seat 4 and one end close to the ball cover 3 , and a central shaft groove 6 for passing through the central shaft is formed in the axial direction of the convex seat 4 , and the central shaft is screwed and connected to the nut groove 5 .

[0023] The yo-yo also includes a central axis, a gasket, a bearing support and a ball bearing. When assembling, two nuts need to be installed in the nut slots 5 of the two spheres 1 respectively, and then the central axis needs to be screwed onto one of the spheres 1 with the nuts installed. After the gasket, the bearing support and the ball bearing are inserted into the central axis, the other sphere 1 is screwed together with it. Then, according to the player's own hand feeling preference, a weight ring 2 of different materials is selected and filled into the inner wall of the two spheres 1. Finally, the ball cover 3 is assembled onto the two spheres 1 to complete the assembly.

[0024] The following description can be made about the material of the weight ring 2: the material of the weight ring 2 can be made of different materials according to the design and weight distribution of the yo-yo ball, including plastic weight rings, aluminum alloy weight rings, composite weight rings stacked with aluminum alloy and plastic, and weight rings made of POM material, etc. By assembling weight rings 2 of various materials and different models, players can better try and choose the accessory set that suits them, meeting the needs of completing yo-yo fancy practice and performance.

[0025] In summary, the utility model can change the weight distribution inside the yo-yo by replacing the counterweight ring 2 inside the yo-yo ball body 1, so that it can adapt to the operation feel and play requirements of more players, and daily play and performance are also more handy.

[0026] In addition, the appearance and size of the utility model can be adjusted according to the size of the yo-yo, but the internal structure and principle remain unchanged.

[0027] 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.
