[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0025] This embodiment relates to a novel joint connection structure, which mainly includes a plurality of joint units 1 that can be interlocked, such as Figure 1 and Figure 3 As shown, the structure can be considered to be composed of two parts, namely, a connecting portion 13 and a base portion 14. The connecting portion 13 is composed of three connecting edges 12, the head ends of the three connecting edges 12 are connected together, and the tail ends are radially extended outward; the base portion 14 is connected to the tail ends of the three connecting edges 12, and at least three connected buckle holes 11 are formed between the three connecting edges 12 and the base portion 14. In addition to being as follows Figure 3 The entity shown in FIG. 1 may also be a connection portion 13 in other directions within the same joint unit 1, such as Figure 1 As shown, one connection part 13 is also the base 14 of other connection parts 13, and the joint unit 1 as a whole forms a hollow frame. The three connection edges 12 correspond to the three buckle holes 11 respectively. When buckling, the three connection edges 12 on one joint unit 1 pass through the three buckle holes 11 on the other joint unit 1 respectively to complete the buckle.

[0026] With such a design, the connecting edges 12 of the joint unit 1 can move flexibly within the size range of the buckle hole 11. There are three buckle holes 11. When the joint unit 1 is buckled, the three connecting edges 12 pass through the three buckle holes 11 respectively. Figure 2 and Figure 3 As shown, the three connecting edges 12 can provide support force to keep the joint unit 1 stable, and the stability is the strongest at this time, while ensuring sufficient mobility. The connection is achieved by the buckle hole 11 on the joint unit 1 and the joint unit 1 buckled with each other, and the movable range depends on the size of the buckle hole 11 and the size of the connecting edge 12 of the joint unit 1, which greatly improves the flexibility. At the same time, the structure is simple, easy to produce and assemble, and saves production costs.

[0027] In this embodiment, there are three buckle holes 11, and the three buckle holes 11 are of the same shape and size, ensuring that the joint unit 1 has the same range of motion when moving in each direction, and ensuring the stability of the connection structure. The three buckle holes 11 are located adjacent to each other, and the angle between any two connecting edges 12 is 120°, taking the head ends of the three connecting edges 12 as the origin, that is, the three connecting edges 12 are evenly distributed around the origin with equal spacing.

[0028] Preferably, the outer side of the joint unit 1 is smoothed, and each edge of the joint unit 1 is chamfered. Since the joint units 1 frequently move, the smooth connection edges 12 can effectively reduce the collisions during movement, reduce the wear of the joint unit 1, and increase the service life.

[0029] On the inner side of the joint unit 1, a depression is provided at the connection between the connecting edges 12. The curvature of the depression can further protect the joint unit 1 from being worn by bumps during movement, while increasing the range of motion of the joint unit 1, further reducing the weight, and optimizing the structure.

[0030] like Figure 2 and Figure 3 As shown, the base of the joint unit 1 is provided with a plug-in column 2 for connecting the doll body part 5. The bottom surface of the plug-in column 2 is D-shaped so that it will not loosen after plugging. In this embodiment, the plug-in column 2 is set at the center point of the three connecting edges 12, and the position on the joint unit 1 opposite to the center point is the center point of the three buckle holes 11. The plug-in column 2 on one joint unit 1 is inserted into the arm part of the doll, and at the same time, the three buckle holes 11 at the other end are buckled to another joint unit 1, and the plug-in column 2 of the other joint unit 1 is then inserted into the body part of the doll, so that the connection of the doll body part 5 can be achieved by two joint units 1. In other embodiments, three or more joint units 1 can be used to complete the connection, and only the joint unit 1 connected to the doll body part 5 is provided with a plug-in column 2, and the joint unit 1 in the middle part is not provided with a plug-in column 2, but is connected to other joint units 1 at both ends. In another embodiment, no plug-in column 2 is provided at all joint units 1, and several joint units 1 are connected head to tail to form a ring to form a unique bracelet structure. The playability of the joint connection structure is improved, and the application is flexible and diverse.

[0031] like Figure 2 and Figure 3 As shown, the joint unit 1 can be a cube or a sphere. In production and application, the joint unit 1 of the corresponding shape can be flexibly selected according to the type of doll and the demand for the range of motion.

[0032] Furthermore, in this embodiment, the joint unit 1 includes a first unit portion 3 and a second unit portion 4, and the first unit portion 3 and the second unit portion 4 can be assembled detachably, and the separation position is preferably set in the middle of the joint unit 1, such as Figure 2 and Figure 3 As shown. In this embodiment, the first unit 3 and the second unit 4 are plugged together through the convex column and the concave hole. When assembling the doll, the first unit 3 and the second unit 4 can be separated first, and the three connecting edges 12 of the second unit 4 are respectively passed through the three buckle holes 11 of another joint unit 1, and then plugged with the first unit 3 to complete the assembly. The detachable design reduces the difficulty of assembly, reduces production costs, and optimizes the user experience.

[0033] In this embodiment, the buckling hole 11 is circular. Since the edge of the buckling hole 11 is an arc, the joint unit 1 can be moved more smoothly after buckling, which reduces the sense of frustration during movement, optimizes the user experience, and reduces friction to extend the service life.

[0034] The present invention also provides a doll, such as Figure 4 and Figure 5 As shown, the doll comprises various body parts 5 of the doll's body and the novel joint connection structure as described above. The various body parts 5 of the doll are connected by the novel joint connection structure as described above. While ensuring mobility, the joint structure of the doll is also very stable, which helps to improve children's interest in playing and stimulate children's creativity.

[0035] The working principle of the present invention is roughly as follows: This structure mainly includes a number of joint units 1 that can be interlocked. The structure can be regarded as consisting of two parts, namely a connecting portion 13 and a base 14. The connecting portion 13 is composed of three connecting edges 12. The head ends of the three connecting edges 12 are connected together, and the tail ends are radially extended outward; the base 14 is connected to the tail ends of the three connecting edges 12, and at least three connected buckling holes 11 are formed between the three connecting edges 12 and the base 14. In addition to being a solid, the base 14 can also be a connecting portion 13 in other directions within the same joint unit 1, that is, one connecting portion 13 is also the base 14 of other connecting portions 13, and the joint unit 1 as a whole forms a hollow frame. The three connecting edges 12 correspond to the three buckling holes 11 respectively. When buckling, the three connecting edges 12 on one joint unit 1 pass through the three buckling holes 11 on the other joint unit 1 respectively to complete the buckling. The movable range depends on the size of the buckle hole 11 and the size of the connecting edge 12 of the joint unit 1, which greatly improves the flexibility. At the same time, the structure is simple, easy to produce and assemble, and the production cost is saved.

[0036] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
