Description

Technical Field

[0001] This utility model relates to the field of basketball technology, and in particular to a novel ball and basketball. Background Technology

[0002] Most existing basketballs, volleyballs, and other ball-shaped structures employ multi-layered composite inflatable structures. On one hand, this requires inflation, causing inconvenience; on the other hand, the surface hardness of traditional inflatable balls is relatively high, making them easy to injure teenagers. Therefore, ball structures made of highly elastic rubber and plastic materials have emerged on the market, such as the elastic ball with a detachable strip disclosed in Chinese patent publication number CN207898893U. However, most ball structures made of highly elastic rubber and plastic materials are prone to yellowing and aging, which can shorten the ball's lifespan during long-term outdoor activities.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods. Unless otherwise specified, the materials and reagents used in the following embodiments can be obtained commercially.

[0015] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] This utility model provides a novel sphere and basketball, wherein the novel sphere includes: a sphere body 10, the sphere body 10 being made of aliphatic TPU material.

[0018] In specific implementation, such as Figure 1 , Figure 2As shown, the novel sphere includes a sphere body 10, which is integrally molded from aliphatic TPU foam material. The sphere body 10 is uniformly molded, without layering or gradients. The aliphatic TPU material is an existing material, a polyurethane material based on aliphatic isocyanate. Aliphatic TPU itself is resistant to yellowing and has good flexibility. With the addition of UV stabilizers, it possesses basic resistance to ultraviolet aging, making it suitable for outdoor or sun-exposed environments. This improves the sphere's resistance to yellowing and aging, thereby extending its service life. The sphere in this embodiment can be applied to volleyballs, basketballs, etc., which will not be elaborated further here.

[0019] The novel sphere provided in this embodiment of the invention features a sphere body 10 made of aliphatic TPU material. On one hand, the aliphatic TPU material significantly improves the sphere's resistance to yellowing and aging, thereby extending its service life. On the other hand, it eliminates the inflation and deflating steps of traditional inflatable spheres, making it more convenient to use. Furthermore, compared to traditional inflatable spheres, the sphere body 10 made of aliphatic TPU has a softer surface, effectively reducing or preventing injuries from impacts, making it especially suitable for teenagers and greatly reducing the risk of injury to them.

[0020] Furthermore, the density of the sphere body 10 is 0.06 g / cm³-0.12 g / cm³.

[0021] Furthermore, the density of the sphere body 10 is one of 0.06 g / cm³, 0.08 g / cm³, 0.09 g / cm³, 0.10 g / cm³, and 0.12 g / cm³.

[0022] In specific implementation, the density of the sphere body 10 is 0.06 g / cm³-0.12 g / cm³, preferably one of 0.06 g / cm³, 0.08 g / cm³, 0.09 g / cm³, 0.10 g / cm³, and 0.12 g / cm³. In this embodiment, a predetermined sphere density is used to make the entire sphere lightweight, thereby reducing the risk of collision injuries to teenagers.

[0023] Furthermore, the surface of the sphere body 10 is coated with a wear-resistant layer.

[0024] Furthermore, the wear-resistant layer is made of polyurea material.

[0025] In specific implementation, a wear-resistant layer is sprayed onto the surface of the sphere body 10. The wear-resistant layer is made of polyurea material, and the wear resistance of the sphere body 10 surface is improved by spraying polyurea material. In this embodiment, the spraying thickness of the wear-resistant layer can be set according to actual needs, and the thickness includes, but is not limited to, 0.5 mm to 3.0 mm, which will not be elaborated here.

[0026] This utility model also provides a basketball, which uses the novel sphere described above. Further, the surface of the sphere body 10 is provided with a plurality of protruding structures 11.
