Description

Technical Field

[0001] This utility model relates to the technical field of children's game equipment, and in particular to a snap-lock game ball assembly structure. By using a special snap-lock design and an appropriate reinforcement mechanism, it can be quickly assembled and is not easy to fall off. Background Technology

[0002] According to medical reports, children who get adequate exercise during their growth will have better development. Therefore, it is even more important to provide a safe and worry-free play environment for children to grow up safely and avoid accidents such as falls.

[0003] Therefore, there are various types of discreet and quick-to-use play equipment on the market, most of which form an enclosed play space. Furthermore, to attract children's attention, toys or small balls are placed inside these play tents or ball pits for them to play with.

[0004] Currently, most of the balls used in these game equipment are made by one-piece blow molding. These balls are lightweight because they contain air inside. However, because the balls are quite thin during blow molding, and since they are intended for children to hold and even use as a form of swimming, they are easily deformed by children and cannot be restored, thus affecting their use. If the balls are made of hard material, they are made by joining two hemispheres together, with screw holes inside, and then fixing them with screws from the outside. This not only results in an incomplete internal space but also leaves holes for locking the screws. Alternatively, the two hemispheres are glued together directly with chemical adhesives or by ultrasonic bonding. The manufacturing process is relatively complex and requires external materials or equipment. There are also significant limitations on the materials used for the two hemispheres, and once fixed, they cannot be disassembled. Therefore, it is necessary to improve the design.

[0005] In view of this, the designer of this case has accumulated many years of experience in mechanical design and proposed a snap-lock fixed game ball assembly structure after conception. It is composed of a first hemisphere and a second hemisphere. The opening of the two hemispheres is provided with a special snap-lock design, and the two hemispheres are provided with appropriate reinforcement mechanisms inside. After they are put together, they can be quickly snapped together and are not easy to fall off after assembly. Utility Model Content

[0006] The purpose of this utility model is to provide a snap-locking game ball assembly structure, including a first hemisphere and a second hemisphere. The first hemisphere has a first opening and an outwardly extending first assembly section with a limiting and anti-slip structure. Four linear snap-lock protrusions are evenly spaced around the first assembly section. The second hemisphere has a second opening and an inwardly extending second assembly section with a limiting and anti-slip structure. Four linear groove holes are evenly spaced around the second assembly section corresponding to the linear snap-lock protrusions. After assembly, each linear snap-lock protrusion is respectively engaged with the game ball assembly. Each linear groove hole forms a fixed structure, ensuring complete engagement of the surfaces of the first and second hemispheres, significantly improving assembly convenience. Furthermore, two first semi-circular reinforcements are formed on the inner wall of the first hemisphere corresponding to the four linear locking protrusions, and two second semi-circular reinforcements are formed on the inner wall of the second hemisphere corresponding to the four linear groove holes. Thus, after assembly, the combined effect of each linear locking protrusion engaging with each linear groove hole and the fixed structure formed by the limiting and anti-slip assembly section and the reinforcement structure significantly enhances its stability.

[0007] To achieve the above objectives, this utility model provides a snap-locking game ball assembly structure, comprising: a first hemisphere having a circular first opening, a first assembly section with a limiting and anti-slip structure extending outward around the first opening, and four linear snap protrusions spaced in four equal parts on the inner wall surface around the first assembly section; and a second hemisphere having a circular second opening, a second assembly section with a limiting and anti-slip structure extending inward around the second opening, and four linear groove holes spaced in four equal parts on the outer wall surface around the second assembly section corresponding to the linear snap protrusions; during assembly, the second assembly section is enclosed within the first assembly section, so that each linear snap protrusion is respectively snapped into each linear groove hole to form multiple stable fixations, and the surfaces of the first hemisphere and the second hemisphere are completely joined.

[0008] In one embodiment, the inner wall of the first hemisphere of this invention forms two first semi-arc reinforcing portions corresponding to the positions of the four linear tenon protrusions. The two first semi-arc reinforcing portions are arranged in a cross shape and pass through the center position of the top of the first hemisphere. Similarly, the inner wall of the second hemisphere forms two second semi-arc reinforcing portions corresponding to the positions of the four linear groove holes. The two second semi-arc reinforcing portions are arranged in a cross shape and pass through the center position of the top of the second hemisphere. Furthermore, the two first semi-arc reinforcing portions intersect at the center position of the top of the first hemisphere to form a first central portion, and the two second semi-arc reinforcing portions intersect at the center position of the top of the second hemisphere to form a second central portion. Furthermore, the inner wall of the first assembly section is provided with a first limiting rib corresponding to the periphery of the second assembly section. This first limiting rib is arranged around the first assembly section. The outer wall of the second assembly section is provided with two second limiting ribs, which are arranged around the second assembly section. These two second limiting ribs clamp the first limiting rib, thus forming a limiting and fixing mechanism. It should be noted that the two first semi-circular reinforcing portions and the first central portion of this invention are areas with a thickness greater than the thickness of the first hemisphere, and the two second semi-circular reinforcing portions and the second central portions are areas with a thickness greater than the thickness of the second hemisphere. This enhances the strength of the locking mechanism, preventing it from separating.

[0009] This utility model utilizes the interconnected and evenly distributed first semi-circular reinforcing parts on the inner wall of the first hemisphere, and the interconnected and evenly distributed second semi-circular reinforcing parts on the inner wall of the second hemisphere. This not only strengthens the strength of the linear tenon protrusions and linear groove holes after they are joined, but also improves the surface strength of the entire sphere after it is joined. Furthermore, the first limiting rib and the second limiting rib not only provide a positioning and limiting effect during installation, but also enhance the strength of the joint. The ingenuity of this utility model is evident here. Attached Figure Description

Detailed Implementation

[0014] To ensure a clear understanding of the contents of this utility model, please refer to the following description and accompanying drawings.

[0015] Please see Figure 1 , Figure 2 and Figure 3 The figures shown are exploded perspective views of various angles of the preferred embodiment of the present invention, as well as sectional views and perspective views of the assembled product. As shown in the following figures, the present invention provides a snap-locked game ball assembly structure 1, including a first hemisphere 11 and a second hemisphere 12.

[0016] The first hemisphere 11 has a circular first opening 111. A first assembly section 112 with a limiting and anti-slip structure extends outwards around the first opening 111. Four linear locking protrusions 113 are spaced four times on the inner wall of the first assembly section 112 according to a four-part division. Furthermore, two first semi-circular reinforcing sections 114 are formed on the inner wall of the first hemisphere 11 corresponding to the four linear locking protrusions 113. These two first semi-circular reinforcing sections 114 are arranged in a cross shape, passing through the center of the top of the first hemisphere 11, and the two first semi-circular reinforcing sections 114... A first central portion 115 is formed at the center of the top of the first hemisphere 11. Then, a first limiting rib 1121 is provided on the inner wall of the first assembly section 112 facing the periphery of the second assembly section 122. The first limiting rib 1121 is arranged around the first assembly section 112. It should be noted that the first semi-circular reinforcing portions 114 and the first central portion 115 of this utility model are areas with a thickness greater than the thickness of the first hemisphere 11, about 1 to 2 times the thickness of the first hemisphere 11, in order to provide the required strength and also achieve the purpose of lightweighting.

[0017] The second hemisphere 12 also has a circular second opening 121. A second assembly section 122 with a limiting and anti-slip structure extends inwards around the second opening 121. Four linear groove holes 123 are provided at equal intervals around the outer wall of the second assembly section 122, corresponding to the linear locking protrusions 113. Furthermore, two second semi-circular reinforcing parts 124 are formed on the inner wall of the second hemisphere 12 at positions corresponding to the four linear groove holes 123. These two second semi-circular reinforcing parts 124 are arranged in a cross shape, passing through the center of the top of the second hemisphere 12, and are intersecting at... A second central portion 125 is formed at the center of the top of the second hemisphere 12. Similarly, two second limiting ribs 1221 are provided on the outer wall of the second assembly section 122. The two second limiting ribs 1221 are arranged around the second assembly section 122, and the first limiting rib 1121 is clamped by the two second limiting ribs 1221 to form a limiting and fixing. It should also be noted that the second semi-arc reinforcing portions 124 and the second central portion 125 of this utility model are areas with a thickness greater than the thickness of the second hemisphere 12. Their thickness is about 1 to 2 times greater than the thickness of the first hemisphere 11 in order to provide the required strength and also take into account the weight reduction.

[0018] Accordingly, the snap-locking game ball assembly structure 1 of this utility model utilizes the first assembly section 112 of the limiting and anti-slip structure extending outward from the first opening 111 of the first hemisphere 11, four linear snap protrusions 113 equally spaced around the first assembly section 112, and the second assembly section 122 of the limiting and anti-slip structure extending inward from the second opening 121 of the second hemisphere 12, four linear groove holes 123 equally spaced around the second assembly section 122 corresponding to the linear snap protrusions 113, and the inner wall of the first hemisphere 11 forms two first hemispheres corresponding to the four linear snap protrusions 113. The arc-shaped reinforcing part 114 and the inner wall of the second hemisphere 12 face each of the four linear groove holes 123 to form two second semi-arc-shaped reinforcing parts 124. During assembly, the first hemisphere 11 and the second hemisphere 12 are directly joined together, and the first assembly section 112 is covered by the second assembly section 122. Each linear locking protrusion 113 is respectively locked into each linear groove hole 123. The combination of the limiting and anti-slip assembly section structure and the reinforcing part structure forms a fixed effect, so that the surfaces of the first hemisphere 11 and the second hemisphere 12 are completely joined to form a flat spherical surface, thereby improving the convenience, stability and strength of the assembly.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, any equivalent or easy changes made by those skilled in the art or those familiar with the technology without departing from the spirit and scope of the present utility model should be covered within the patent scope of the present utility model.
