Description

Technical Field

[0001] The utility model relates to a high-elasticity basketball winding middle tire, belonging to the technical field of basketballs. Background Art

[0002] The "middle tire" in a basketball is an important part of the basketball structure. It is located between the inner liner and the outer skin of the basketball. Its main function is to fix the shape of the basketball, protect the inner liner, and serve as a transition layer between the winding and the outer skin. The middle tire is usually made of rubber, and there are ordinary middle tires, foamed middle tires, weighted middle tires and other types.

[0003] For example, CN209019862U discloses a dynamically inflatable basketball inner tube. By filling the inner tube with a gas-generating solid that generates nitrogen, the inner tube can automatically generate nitrogen during the vulcanization process. The generated nitrogen is distributed in the internal cavity of the inner tube, increasing the pressure inside the inner tube and improving the elasticity and durability of the basketball inner tube. By coating the solid sodium nitrite and solid ammonium chloride with a slow-release layer on the outside, the slow-release layer can change from a solid state to a liquid state after the mold is closed, so that the gas-generating solid coated therein generates nitrogen when heated and fills the inner tube cavity, which has a good slow-release effect and realizes the automatic inflation process. By setting the bonding edge and the wire groove, the adhesive area of ​​the upper inner liner and the lower inner liner is increased, the air tightness of the inner tube is improved, thereby improving the air tightness of the basketball inner tube. The wire groove also increases the area where the inner tube and the outer skin are attached, which is used to strengthen the firmness of the skin, increase the durability of the basketball inner tube, and generally improve the elasticity and durability of the basketball inner tube. However, since the gas-generating fixing and slow-release layer is located in a corner of the inner tube, the basketball itself is not in a balanced state. The movement trajectory of the basketball is easily deviated during basketball play, which is not conducive to the user's control of the basketball. Although the air tightness of the middle tube can be improved by bonding the edges and grooves, the elasticity of the middle tube is only slightly improved. Therefore, optimization and improvement are needed. Utility Model Content

[0004] The utility model aims to provide a high-elastic basketball winding middle tube. An inner rubber layer is arranged inside the inner tube, and a gas-generating solid is arranged in each circular protrusion in the inner rubber layer. Since the circular protrusions are evenly arranged inside the inner rubber layer, the weight distribution of the basketball body itself is more balanced, making it easier for the user to control the basketball. At the same time, bumps and elastic particles are arranged on the surface of the middle tube. The middle tube, bumps and elastic particles made of natural rubber have good elasticity themselves. The bumps and elastic particles can push the basketball body and the middle tube to rebound quickly when the basketball body contacts the ground, thereby effectively improving the elasticity of the basketball body to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-elastic basketball winding middle tube comprises a basketball body, wherein the basketball body comprises a skin, wherein the skin is provided with a transverse annular groove and a longitudinal annular groove, wherein a middle tube is provided inside the skin, wherein a nylon winding yarn is provided inside the middle tube, wherein an inner tube is provided inside the nylon winding yarn, wherein an inner tube is provided inside the inner tube, wherein a gas-generating solid is provided inside the inner rubber layer, and wherein a slow-release layer is wrapped around the outside of the gas-generating solid.

[0007] Furthermore, a plurality of convex blocks are arranged around the outer periphery of the middle tire, and the convex blocks are embedded in the inner part of the surface layer.

[0008] Furthermore, a plurality of elastic particles are arranged on the top of the protrusion, and the elastic particles are rectangular and evenly arranged on the upper surface of the protrusion.

[0009] Furthermore, the middle tire, the convex blocks and the elastic granular material are all made of natural rubber, a plurality of air cavities are provided inside the middle tire, and the gas filled in the air cavities is nitrogen.

[0010] Furthermore, the gas-generating solid material is solid sodium nitrite and solid ammonium chloride, and the sustained-release layer material is polyethylene wax.

[0011] Furthermore, the inner rubber layer is provided with a plurality of circular protrusions, and the gas-generating solid and the slow-release layer are arranged inside the circular protrusions.

[0012] Furthermore, a plurality of through holes are provided inside the inner rubber layer, and the through holes are provided on the circular protrusion and communicated with the sustained-release layer.

[0013] The beneficial effects of the utility model are:

[0014] 1. By arranging an inner rubber layer inside the inner tube and arranging the gas-generating solid in each circular protrusion in the inner rubber layer, since the circular protrusions are evenly arranged inside the inner rubber layer, the weight distribution of the basketball body itself is more balanced, making it easier for the user to control the basketball.

[0015] 2. By setting bumps and elastic particles on the surface of the middle tire and setting an air cavity inside the middle tire, the air cavity can rebound after compression to increase the elasticity of the middle tire. Since the middle tire, bumps and elastic particles made of natural rubber have good elasticity themselves, and the bumps and elastic particles can push the basketball body and the middle tire to rebound quickly when the basketball body contacts the ground, thereby effectively improving the elasticity of the basketball body.
