Technical Field
[0001] The utility model relates to the technical field of toys, in particular to a toy ball head structure, a ball socket structure and a toy thereof. Background Art
[0002] Many simulation toys currently on the market can realistically replicate human body movements, such as dolls used for entertainment and display purposes. The various movements of these dolls are often completed with the help of movable joints, which increases the fun of the toys.
[0003] Most of the existing movable joints use a ball socket socket to fit on the ball head, so that the limb connected to the ball head can rotate on the ball socket socket to achieve various actions. Since the ball head 1 is made of plastic material during production, the shrinkage between the outer surface 11 and the inner hole 12 of the ball head 1 cannot be solved due to the wall thickness after the mold is formed. Figure 2 As shown, the size cannot be effectively controlled, and the production sizes vary, resulting in a poor experience in joint assembly, which greatly affects the fun of the toy.

[0006] The outer surface of the ball head has a plurality of grooves arranged at intervals, so that the thickness of a partial area of the outer surface of the ball head becomes thinner, thereby forming a thick and thin structure on the outer surface of the ball head. A sliding support surface is formed between two adjacent grooves, and all the sliding support surfaces are connected to each other to form a grid support spherical surface. The ball head structure can form a rotating pair with its matching ball socket structure by means of the grid support spherical surface to realize the rotation function.

[0023] Ball head outer surface 11
[0024] Groove 111
[0025] Sliding support surface 112
[0026] Inner hole 12 DETAILED DESCRIPTION
[0027] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.
[0028] The utility model provides a toy ball head structure, such as Figure 1 As shown, it includes a ball head outer surface 11 and an inner hole 12. The inner hole 12 is a splicing hole for connecting the ball head structure to other building blocks. It can be a circular hole, a square hole, a regular polygonal hole structure, etc. The ball head outer surface 11 is larger than half of the sphere, and the thickness of the ball head structure is formed from the inner wall of the inner hole 12 to the ball head outer surface 11.
[0029] The outer surface 11 of the ball head has a plurality of grooves 111 arranged at intervals, so that the thickness of some areas of the outer surface 11 of the ball head becomes thinner. The utility model can effectively reduce the size problem caused by shrinkage by designing the outer surface 11 of the ball head to have a structure with different thicknesses and arranged at intervals, while ensuring uniform force during rotation. A sliding support surface 112 is formed between two adjacent grooves 111, and all the sliding support surfaces 112 are connected to each other to form a grid support spherical surface. The ball head structure can form a rotating pair with its matching ball socket structure by means of the grid support spherical surface, thereby realizing the rotation function. For example, it can be applied to the joint structure of dolls, etc., which improves the matching accuracy of the toy, provides a good toy experience, and increases the fun of the toy.
[0030] It should be noted that in order not to affect the quality of the product and improve the dimensional accuracy of the product, the distance between two adjacent grooves 111 is less than or equal to the maximum thickness, which is also conducive to reducing the impact of shrinkage on product accuracy. When the ball head structure is assembled into the ball socket structure, the contact area between the ball head structure and the ball socket structure is not less than half of the area of the outer surface 11 of the ball head, which can ensure the effective support force between the ball head structure and the ball socket structure and ensure the stability of the building blocks after splicing.
[0031] like Figure 1 As shown, the circumference of the mouth of the inner hole 12 is a plane, and the mouth of the inner hole 12 has a chamfered structure, so that the entire structure has no sharp edges, which makes it safer for children to play and increases the practicality of the toy.
[0032] Specifically, the arrangement of the grooves 111 on the outer surface 11 of the ball head can adopt a variety of structural forms. In a possible embodiment, a plurality of grooves 111 are evenly arranged on the outer surface 11 of the ball head, such as Figure 1 As shown, the shrinkage of the entire ball head structure during the molding process is effectively controlled, greatly improving the molding quality and precision of the product.
[0033] In practical applications, the structures of the plurality of grooves 111 may be all the same, partially the same, or all different. For example, the groove 111 may be a circular groove, a square groove, or a groove body of other structures. To increase the convenience of assembly, the mouth of the groove 111 may have a chamfered structure.
[0034] The utility model also provides a ball socket structure, which matches the ball head structure of the toy, so that the ball head structure can be assembled into the inside of the ball socket structure and form a revolving pair together, so as to realize the joint rotation function. It should be noted that the inner diameter of the mouth of the ball socket structure is smaller than the outer diameter of the grid supporting spherical surface, so that the ball head structure assembled into the ball socket structure is not allowed to be separated from the ball socket structure in a natural state, and the ball head structure is allowed to leave the ball socket structure under the drive of hand force, that is, the mouth of the ball socket structure and / or the grid supporting spherical surface have a certain elasticity, which is conducive to the smoothness of assembly and the stability in a natural state, and increases the high-end sense and fun of the toy.
[0035] The utility model also provides a toy, including a toy ball head structure. In specific design, a variety of toys can apply the ball head structure of the utility model. For example, a multi-joint humanoid doll can use a ball head structure in conjunction with a ball socket structure at the joint to realize the joint movement function, thereby increasing the simulation and interest of the toy.
