Description

[Technical Field]

[0001] This invention relates to the technical field of children's game equipment, and relates to an assembly structure for a fixed ball with a mortise and tenon joint that can be assembled quickly and is difficult to come off by using a reinforcing mechanism suitable for a special mortise and tenon joint design. [Background technology]

[0002] According to medical reports, children can achieve good growth by continuing to exercise in a moderate manner throughout their development. During this period, it is even more important to provide a safe and worry-free environment for children to grow up safely and avoid falls.

[0003] Therefore, there are various types of secret and quick-play game equipment on the market, and most of them form a play space in an enclosed area. In addition, to attract children's attention, toys and small balls are sometimes placed inside these game tents and ball pools.

[0004] Currently, most of the small balls used in these games are made using one-piece blow molding. This type of ball has the advantage of being lightweight because it contains air inside, but the thickness of the ball is thin during blow molding, and since the ball is intended for children to play with in the pool, it is prone to deformation when pressed by children and cannot return to its original shape, which affects its use. If a hard ball is to be made, after joining the two half balls, a screw hole structure is provided inside and the ball is fixed with a screw from the outside. This not only creates unevenness in the internal space, but also leaves holes for the fixing screws. It is also possible to directly bond the two half balls with adhesive or to bond them using ultrasound, but the manufacturing process is complicated, requires external materials and equipment, and there are significant limitations on the materials that can be used for the two half balls. Furthermore, once the balls are fixed, they cannot be separated or disassembled, so improvements are needed.

[0005] In light of these issues, the inventor has utilized his many years of experience in machine design to propose an assembly structure for a fixed ball with a mortise and tenon joint. It consists of a first hemisphere and a second hemisphere, with a special mortise and tenon joint design at the openings of the two hemispheres, and a suitable reinforcement mechanism inside the two hemispheres, which allows for a quick mortise and tenon joint and makes it difficult for the ball to come loose after assembly. Summary of the Invention [Problem to be solved by the invention]

[0006] One objective of the present invention is to provide an assembly structure for a fixed mortise and tenon joint, which includes a first hemisphere and a second hemisphere. The first hemisphere has a first opening and a first assembly step extending outward with a position limiting and anti-slip structure, and the periphery of the first assembly step is provided with four linear mortise and tenon joint protrusions spaced at quarter intervals. The second hemisphere has a second opening and a second assembly step extending inward with a position limiting and anti-slip structure, and the periphery of the second assembly step is provided with four linear mortise and tenon joint grooves spaced at quarter intervals at positions corresponding to the linear mortise and tenon joint protrusions. After assembly, each linear tenon joint convex part is fixed to each linear tenon joint concave hole by tenon joint, so that the surfaces of the first and second hemispheres are completely joined together, which greatly improves the convenience of assembly. Furthermore, two first semi-arc reinforcing sections are formed on the inner wall surface of the first hemisphere at positions corresponding to the four linear tenon joint protrusions, and two second semi-arc reinforcing sections are formed on the inner wall surface of the second hemisphere at positions corresponding to the four linear tenon joint recessed holes. During assembly, each linear tenon joint protrusion is tenon-jointed to each linear tenon joint recessed hole, and a fixing effect is achieved by the position limiting and anti-slip assembly structure and reinforcing section structure, thereby greatly improving the stability effect. [Means for solving the problem]

[0007] To achieve the above object, the assembly structure of the tenon joint fixed type ball of the present invention comprises a first hemisphere having a first circular opening, a first assembly step having a position limiting and anti-slip structure facing outward along the periphery of the first opening, and four linear tenon joint protrusions arranged at quarter intervals on the inner wall surface around the first assembly step, and a second circular opening, a second assembly step having a position limiting and anti-slip structure facing inward along the periphery of the second opening, and four linear tenon joint slots arranged at quarter intervals on the outer wall surface around the second assembly step corresponding to the linear tenon joint protrusions. During assembly, each linear tenon joint protrusion is tenon-joined to each linear tenon joint slot, and the second assembly step is installed inside the first assembly step to form a multi-layered fixation, so that the surfaces of the first and second hemispheres are completely joined.

[0008] In one embodiment, two first semi-arc reinforcing portions are formed on the inner wall surface of the first hemisphere at positions corresponding to the four linear tenon joint protrusions of the present invention, and the two first semi-arc reinforcing portions intersect with each other in a crisscross pattern and pass through the center of the top of the first hemisphere. In addition, two second semi-arc reinforcement portions are formed on the inner wall surface of the second hemisphere at positions corresponding to the four linear tenon joint grooves, and the two second semi-arc reinforcement portions are installed in a crisscross pattern and pass through the center position of the top of the second hemisphere. Furthermore, two first semi-arc-shaped reinforcing portions are positioned across the center of the top of the first hemisphere, forming a first central portion thereon. Two second semi-arc-shaped reinforcing portions are positioned across the center of the top of the second hemisphere, forming a second central portion thereon. A first limiting rib is provided on the inner wall surface of the first assembly section at the peripheral edge corresponding to the second assembly section, and the first limiting rib is annularly disposed on the first assembly section. Two second limiting ribs are provided on the outer wall surface of the second assembly section, and the two second limiting ribs are annularly disposed on the second assembly section, sandwiching the first limiting rib between the two second limiting ribs to form a position limiting and fixed structure. The thickness of the multiple first semi-arc-shaped reinforcing portions and the first central portion of the present invention is greater than the thickness of the first hemisphere, and the thickness of the multiple second semi-arc-shaped reinforcing portions and the second central portion of the present invention is greater than the thickness of the second hemisphere, improving the strength of the tenon joint and making it less likely to come loose. The multiple first semi-arc reinforcing portions are interconnected and evenly distributed on the inner wall surface of the first hemisphere, and the multiple second semi-arc reinforcing portions are similarly interconnected and evenly distributed within the second hemisphere, which not only enhances the strength of the multiple linear tenon joint convex blocks and the multiple linear tenon joint concave slots after bonding, but also improves the surface strength of the entire sphere after bonding. Furthermore, the first position limiting rib and the plurality of second position limiting ribs not only limit the position when installed, but also increase the strength of the joint, fully demonstrating the ingenuity of the design of the present invention.

Four linear tenon joint protrusions 113 are installed at quarter intervals on the inner wall surface of the first assembly section 112. Furthermore, two first semi-arc-shaped reinforcing portions 114 are formed on the peripheral inner wall of the first hemisphere 11 at locations corresponding to the four linear tenon joint protrusions 113. The two first semi-arc-shaped reinforcing portions 114 cross each other and pass through the center of the top of the first hemisphere 11. The two first semi-arc-shaped reinforcing portions 114 also cross and are located at the center of the top of the first hemisphere 11 to form a first center portion 115. A first position limiting rib 1121 is formed on the peripheral edge of the inner wall of the first assembly section 112 corresponding to the second assembly section 122, and the first position limiting rib 1121 is annularly disposed on the first assembly section 112. The thickness of the multiple first semi-arc-shaped reinforcing portions 114 and the first center portion 115 of the present invention is greater than the thickness of the first hemisphere 11, approximately 1 to 2 times that of the first hemisphere 11, thereby ensuring the required strength and achieving the goal of lightweight construction.

[0013] The second hemisphere 12 also has a circular second opening 121, and a second assembly stage 122 with a position limiting and anti-slip structure extends inward around the second opening 121.Furthermore, a plurality of linear tenon joint protrusions 113 correspond to the peripheral outer wall surface of the second assembly stage 122, and four linear tenon joint recess holes 123 are similarly installed at quarter-spaced intervals. Furthermore, two second semi-arc reinforcing portions 124 are formed on the inner wall surface of the second hemisphere 12 at positions corresponding to the four linear tenon joint grooves 123, and the two second semi-arc reinforcing portions 124 cross and pass through the center of the uppermost part of the second hemisphere 12, and two more second semi-arc reinforcing portions 124 cross and are positioned at the center of the uppermost part of the second hemisphere 12 to form a second center portion 125. Similarly, two second position limiting ribs 1221 are formed on the outer wall surface of the second assembly section 122, and the two second position limiting ribs 1221 are arranged in a ring shape on the second assembly section 122, and the two second position limiting ribs 1221 clamp the first position limiting rib 1121 to form a position limiting and fixed position. Similarly, the thickness of the multiple second semi-arc reinforcing portions 124 and the second central portion 125 of the present invention is greater than the thickness of the second hemisphere 12, and is approximately 1 to 2 times greater than that of the first hemisphere 11, thereby ensuring the necessary strength and achieving weight reduction.

The second assembly section 122, which has a position limiting and anti-slip structure extending inward from the second opening 121 of the second hemisphere 12, has four linear tenon joint slots 123 arranged at quarter intervals around its periphery, corresponding to the linear tenon joint protrusions 113. Two first semi-arc reinforcing sections 114 are molded on the inner wall of the first hemisphere 11 at positions corresponding to the four linear tenon joint protrusions 113, and two second semi-arc reinforcing sections 124 are molded on the inner wall of the second hemisphere 12 at positions corresponding to the four linear tenon joint slots 123. During assembly, the first hemisphere 11 and the second hemisphere 12 are directly fitted together. The second assembly section 122 is covered by the first assembly section 112, and each linear tenon joint protrusion 113 is fitted into each linear tenon joint recess 123, respectively, thereby providing a fixed effect through the position limiting, anti-slip assembly structure, and reinforcement structure, and the surfaces of the first hemisphere 11 and the second hemisphere 12 are completely fitted together to form a flat spherical surface, thereby achieving the goals of improving convenience, stability, and durability after assembly.
