Abstract
Description
Technical Field
[0001] This application relates to the field of sports equipment technology, and in particular to a hexagonal reactive ball. Background Technology
[0002] The hexagonal reaction ball is a training tool specifically designed to improve reaction speed, agility, and body coordination. Its hexagonal design differs from traditional spheres, making its bounce direction more random and unpredictable. The hexagonal reaction ball consists of a main body and six feet. When the ball contacts the ground or other objects, the different angles and contact surfaces of the six feet cause it to bounce irregularly in various directions, increasing the difficulty and challenge of training.
[0003] Currently, hexagonal reaction balls with varying training difficulties are designed for different user groups. This is mainly achieved by changing the size of the ball's feet, such as altering the curvature of the feet, or by changing the material of the feet. For example, using a particularly soft silicone material, which has low elasticity and is less challenging, is suitable for children to play with. However, since hexagonal reaction balls are injection molded in one piece, the material is usually changed as a whole.
[0004] However, when different groups of people play together, or when they experience hexagonal reaction balls of different training difficulties at the same time, it is necessary to purchase multiple specifications. Moreover, the hexagonal reaction balls used need to be replaced with more difficult ones as training progresses. Overall, the hexagonal reaction balls on the market cannot be adjusted for difficulty and are relatively limited, so users need to purchase multiple specifications at the same time. Summary of the Invention
[0005] This application aims to at least partially address one of the aforementioned technical problems in the prior art. To this end, embodiments of this application provide a hexagonal reaction ball, which allows for the disassembly and installation of the ball feet via a quick-release structure, enabling adjustments to training difficulty by replacing the ball feet.
[0006] A hexagonal reactive sphere according to an embodiment of this application includes a sphere, the surface of which is divided into multiple connecting regions; and multiple feet, each connecting region being connected to at least one foot. The feet are detachably connected to the sphere via a quick-release structure. The inner side of each foot is a conforming surface, the curvature of which is the same as the curvature of the sphere's surface, so that the conforming surface conforms to the sphere's surface. The quick-release structure includes a first connecting component and a second connecting component connected to each other. The first connecting component includes a connecting hole formed on the sphere, and the second connecting component includes a post disposed on one side of the conforming surface of the foot. The post connects the foot to the sphere by being inserted into the connecting hole, or removes the foot from the sphere by being pulled out of the connecting hole.
[0007] In an optional or preferred embodiment, the outer surface of the ball foot is provided with a plurality of anti-slip protrusions, the anti-slip protrusions being hemispherical.
[0008] In an optional or preferred embodiment, the ball foot includes a first foot and a second foot that are stacked together, the fitting curved surface is disposed on the inner side of the first foot, and the diameter of the second foot is smaller than the diameter of the first foot.
[0009] In an optional or preferred embodiment, the outer periphery of the insertion post is provided with a plurality of annular flanges so that when the insertion post is inserted into the connection hole, the annular flanges are in an interference fit with the connection hole.
[0010] In an optional or preferred embodiment, the insert is frustum-shaped, the diameter of the insert gradually decreases from one end of the mating surface of the ball foot toward the end, and the diameter of the connecting hole gradually decreases from one end of the opening toward the bottom wall.
[0011] In an optional or preferred embodiment, the ball foot and the insert are integrally formed.
[0012] In an optional or preferred embodiment, the insert is provided with an external thread, and the connecting hole is provided with an internal thread. The external thread matches the internal thread, thereby threading the insert to the connecting hole.
[0013] In an optional or preferred embodiment, the first connecting assembly includes an insert nut inserted into the sphere, the sphere having a first mounting hole for the insert nut to be inserted and connected, the screw hole of the insert nut being the connecting hole, and the ball foot having a second mounting hole for the post to be inserted and connected.
[0014] In an optional or preferred embodiment, the outer wall of the insert nut is provided with a first knurling, and the portion of the insert located in the second mounting hole is provided with a second knurling.
[0015] In an optional or preferred embodiment, the outer wall of the insert nut is provided with a plurality of first anti-disengagement protrusions extending radially outward, and the portion of the insert located within the second mounting hole is provided with a plurality of second anti-disengagement protrusions extending radially outward.
[0016] Based on the above technical solution, the embodiments of this application have at least the following beneficial effects: In the above technical solution, the ball foot is connected to the ball through a quick-release structure, and various ball feet of different elastic materials and different sizes can be designed. Users can install them on the ball according to their needs. When replacement is required, the ball foot can be removed by simply pulling the insertion post of the ball foot out of the connection hole of the ball, thereby replacing it and meeting the user's needs to adjust the training difficulty.

[0039] Example 1
[0040] Reference Figures 1 to 4 This embodiment describes a hexagonal reaction ball, including a ball 11 and a plurality of ball feet 21.
[0041] like Figure 3 As shown, the surface of sphere 11 is divided into multiple connecting regions 12, and then referring to... Figure 2 Each connecting region 12 is connected to at least one ball foot 21. In this embodiment, the spherical surface of the sphere 11 is divided into six connecting regions 12, and each connecting region 12 is connected to one ball foot 21. The connected state is as follows: Figure 1 As shown, Figure 1 The hexagonal reaction ball presented is the same as the existing hexagonal reaction ball.
[0042] In this embodiment, the ball foot 21 is detachably connected to the ball 11 via the quick-release structure 30. The inner side of the ball foot 21 is a fitting surface 22, and the curvature of the fitting surface 22 is the same as the curvature of the spherical surface of the ball 11, so that the fitting surface 22 fits the spherical surface of the ball 11.
[0043] Specifically, the quick-release structure 30 includes a first connecting component and a second connecting component that are interconnected. The first connecting component includes a connecting hole 31 formed on the ball 11, and the second connecting component includes a post 32 disposed on the side of the ball foot 21 that conforms to the curved surface 22. Figure 9 The insert 32 is inserted into the connection hole 31 to attach the ball foot 21 to the ball 11, or is pulled out of the connection hole 31 to remove the ball foot 21 from the ball 11.
[0044] Understandably, the ball foot 21 is connected to the ball 11 via a quick-release structure 30. In practical applications, ball feet made of various elastic materials can be designed, such as softer silicone, which has slightly weaker elasticity and a relatively lower reflection speed and height, suitable for children to play with; or harder rubber, which has stronger elasticity to increase the ball's rebound force and speed. Those skilled in the art can select materials based on existing elastic materials to manufacture the ball 11 and ball foot 12. Of course, ball feet of different sizes can also be designed simultaneously. The ball foot is usually hemispherical, and ball feet of different diameters are designed. Due to the different curvatures, the launch angles are also different, and because of the different sizes, the rebound forces are also different.
[0045] Users can install ball feet of the same specification and material onto the ball as needed, or combine different ball feet in any way. When replacement is required, combine... Figure 9 To understand this, the ball foot 21 can be removed and replaced simply by pulling the pin 32 of the ball foot 21 out of the connecting hole 31 of the ball body 11; when installing the ball foot 21, the pin 32 of the ball foot 21 is inserted into the connecting hole 31 of the ball body 11.
[0046] In this embodiment, the quick-release structure 30, specifically, is as follows: Figure 9 As shown, the outer periphery of the insertion post 32 is provided with several annular flanges 321. The ball foot 21 is integrally formed with the insertion post 32, and the annular flanges 321 are integrally formed with the insertion post 32, both of which are made of elastic material. When the insertion post 32 is inserted into the connecting hole 31, the annular flanges 321 are compressed. At this time, the annular flanges 321 and the connecting hole 31 are interference-fitted, thereby firmly fixing the insertion post 32 in the connecting hole 31.
[0047] Furthermore, such as Figure 9 As shown, the insertion post 32 is shaped like a frustum. The diameter of the insertion post 32 gradually decreases from one end of the mating curved surface 22 of the ball foot 21 towards the end. The diameter of the connecting hole 31 gradually decreases from one end of the opening towards the bottom wall. It can be understood that the end size of the insertion post 32 is smaller than the opening end of the connecting hole 31, which facilitates quick alignment with the opening of the connecting hole 31 and enables quick insertion and installation.
[0048] In addition, the connection area 12 is provided with multiple connection holes 31. In this embodiment, as shown... Figure 3Each connecting area 12 of the sphere 11 is provided with five connecting holes 31, the specific number of which can be adjusted. Each connecting area 12 corresponds to one or more ball feet 21. If the ball foot is larger, it is installed in the connecting hole 31 at the center; if the ball foot is smaller, it can be installed in any connecting hole 31 of the connecting area 12. Furthermore, multiple ball feet 21 can be installed in the same connecting area 12, thereby increasing the diversity of the hexagonal reaction ball's ball feet and increasing the fun during training.
[0049] The boundary between adjacent connecting areas 12 on the sphere 11 can be identified by setting an identification mark. The identification mark can be in the form of a groove, which can be set in advance in the injection mold or processed after the sphere is made.
[0050] Example 2
[0051] Reference Figure 5 and Figure 6 In this embodiment, unlike in embodiment one, the outer surface of the ball foot 21 is provided with a plurality of anti-slip protrusions 23. The anti-slip protrusions 23 are hemispherical, and the purpose of providing the anti-slip protrusions 23 is to facilitate gripping the hexagonal reaction ball.
[0052] In this embodiment, ball feet 21 of different sizes are shown, which can be used as a reference by those skilled in the art.
[0053] Example 3
[0054] Reference Figure 7 and Figure 8 In this embodiment, unlike Embodiment 1, the ball foot 21 includes a first foot 211 and a second foot 212 stacked together. The conforming curved surface 22 is disposed on the inner side of the first foot 211, and the diameter of the second foot 212 is smaller than the diameter of the first foot 211. The stacked first foot 211 and second foot 212 facilitate the gripping of the hexagonal reaction ball, and also create ball feet with different rebound forces for ball feet made of the same material.
[0055] It should be noted that the above three embodiments demonstrate hexagonal reaction balls with different combinations of ball feet 21. In actual use, users can combine them arbitrarily and are not limited to the examples in the above three embodiments.
[0056] Reference Figure 10 This application also presents another structural form of the quick-release structure 30, which can be applied to the above embodiments.
[0057] Specifically, such as Figure 10As shown, the insert 32 is provided with an external thread 322, and the connecting hole 31 is provided with an internal thread 312. The external thread 322 and the internal thread 312 are matched, so that the insert 32 and the connecting hole 31 are threadedly connected.
[0058] In application, preferably, the first connecting assembly includes an insert nut 311 inserted into the ball 11. The ball 11 has a first mounting hole for inserting the insert nut 311 into the ball, and the threaded hole of the insert nut 311 is a connecting hole 31. The ball foot 21 has a second mounting hole for inserting the post 32 into the ball. It is understood that by threading the post 32 to the insert nut 311, the ball foot 21 can be connected to the ball 11, allowing for quick installation. Similarly, disassembly is also very quick.
[0059] Furthermore, the outer wall of the insert nut 311 is provided with a first knurling 313, and the portion of the insert 32 located within the second mounting hole is provided with a second knurling 323. It is understood that the ball 11 and the ball foot 21 are typically manufactured by injection molding. Before the plastic is injected, the insert nut 311 and the insert 32 are respectively fitted into the corresponding mold inserts for fixation before the injection of plastic. By providing the first knurling 313 on the outer wall of the insert nut 311, it can be ensured that the insert nut 311 does not fall out of the first mounting hole of the ball 11; by providing the second knurling 323 on the insert 32, it can be ensured that the insert 32 does not fall out of the second mounting hole of the ball foot 21.
[0060] Reference Figure 11 and Figure 12 This application also presents another structural form of the quick-release structure 30, which can be applied to the above embodiments.
[0061] Specifically, the outer wall of the insert nut 311 is provided with four radially outwardly extending first anti-detachment protrusions 314, and the portion of the insert 32 located within the second mounting hole is provided with four radially outwardly extending second anti-detachment protrusions 324. It can be understood that before plastic injection, the insert nut 311 and the insert 32 are respectively fitted into the corresponding mold inserts and fixed before plastic injection. After manufacturing, the first anti-detachment protrusions 314 can ensure that the insert nut 311 does not fall out of the first mounting hole of the ball 11, and the second anti-detachment protrusions 324 can ensure that the insert 32 does not fall out of the second mounting hole of the ball foot 21.
[0062] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
