Technical Field

[0001] This utility model relates to the field of doll technology, specifically to the joint connection structure of doll toys. Background Technology

[0002] Doll products are derivative products based on characters from animation films, comic books, and online games, as well as original cartoon animals and characters. Xinian Liangpin dolls differ from traditional toys; they possess greater cultural connotations, richer storylines, and more individual and personalized concepts. Therefore, dolls are more beloved and appreciated by adults.

[0003] To showcase the flexibility and versatility of rigid figurines, the joints of rigid figurines are usually designed to be movable. The traditional joint connection structure of figurines uses a rotating connecting shaft. This method can enable the joint to move, but it has the drawback that the direction of rotation is fixed and the figurine cannot maintain stability after rotation. Utility Model Content

[0004] The purpose of this invention is to provide a joint connection structure for doll toys. A fixing post on the second joint connector passes through a through hole in the first joint connector, and a limiting ring limits the first and second joint connectors, maintaining their flexible rotation. The limiting structure then adjusts the first and second joint connectors, ensuring stability after adjustment. Furthermore, the other ends of the first and second joint connectors are also movably connected, further enhancing the flexibility of the joint. This allows for multi-directional rotational adjustment while maintaining joint stability, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a joint connection structure for a doll toy, comprising:

[0006] First joint connector and second joint connector;

[0007] The first joint connector has a first contact plane on one side and the second joint connector has a second contact plane on one side. A fixing post is fixed at the center of the second contact plane. The first joint connector has a through hole, one end of which is located at the center of the first contact plane. The end of the fixing post away from the second joint connector passes through the through hole and is provided with a limit ring. A limit structure is also provided between the first joint connector and the second joint connector.

[0008] Preferably, the limiting structure includes multiple sets of limiting protrusions disposed on the first contact plane, and multiple sets of limiting grooves formed on the second contact plane, wherein the limiting protrusions and limiting grooves are engaged with each other.

[0009] Preferably, a countersunk hole is provided on the side of the first joint connector away from the first contact plane, the limiting ring is located in the countersunk hole, and the end of the limiting ring away from the fixing post is smoothly connected to the outer side of the first joint connector.

[0010] Preferably, the outer side of the limiting protrusion is arc-shaped, the inner wall of the limiting groove is a smooth arc surface, and both the limiting protrusion and the limiting groove are arranged in a ring array around the center of the fixing column.

[0011] Preferably, the ends of the first joint connector and the second joint connector away from contact are respectively provided with movable connection structures. The movable connection structure includes an annular groove formed at one end of the first joint connector and the second joint connector, and the ends of the first joint connector and the second joint connector near the annular groove are frustoconical.

[0012] Preferably, the movable connection structure includes an annular groove formed on the outer side of one end of the first joint connector, and one end of the second joint connector is spherically shaped.

[0013] Preferably, the first joint connector is provided with two sets of parallel outer first contact planes, the second joint connector is provided with two sets of inner second contact planes that fit with the first contact planes, and the fixing post is fixed between the two sets of second contact planes.

[0014] Preferably, it further includes transition joint connectors, wherein the first joint connector and the second joint connector are movably connected to both ends of the transition joint connector, respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses the mutual contact of the first contact plane and the second contact plane to make the first joint connector and the second joint connector in active contact. Then, through the cooperation of the fixing post and the through hole, the second joint connector and the first joint connector can rotate movably. At the same time, under the restriction of the limiting structure, the first joint connector and the second joint connector are kept stable after rotating a certain angle. Then, the other end of the first joint connector and the second joint connector are also provided with a movable connection structure to further increase the direction of joint movement, increase the joint movement angle, and improve the flexibility of the doll.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] like Figures 1-3 The joint connection structure of the doll toy shown includes:

[0034] First joint connector 1 and second joint connector 2;

[0035] The first joint connector 1 has a first contact plane 3 on one side and the second joint connector 2 has a second contact plane 4 on one side. A fixing post 5 is fixed at the center of the second contact plane 4. The first joint connector 1 has a through hole 6, one end of which is located at the center of the first contact plane 3. The end of the fixing post 5 away from the second joint connector 2 passes through the through hole 6 and is provided with a limiting ring 7. The side of the first joint connector 1 away from the first contact plane 3 has a countersunk hole 10. The limiting ring 7 is located in the countersunk hole 10. The end of the limiting ring 7 away from the fixing post 5 is smoothly connected to the outer side of the first joint connector 1. A limiting structure is also provided between the first joint connector 1 and the second joint connector 2.

[0036] The first joint connector 1 and the second joint connector 2 are respectively provided with a movable connection structure at the ends away from the contact. The movable connection structure includes an annular groove 11 opened at one end of the first joint connector 1 and the second joint connector 2. The ends of the first joint connector 1 and the second joint connector 2 near the annular groove 11 are truncated.

[0037] The annular groove 11 provided at the other end of the first joint connector 1 and the second joint connector 2 allows the first joint connector 1 and the second joint connector 2 to rotate around their own central axis, thus enabling flexible rotation of the joint.

[0038] The limiting structure includes multiple sets of limiting protrusions 8 disposed on the first contact plane 3, and multiple sets of limiting grooves 9 provided on the second contact plane 4, wherein the limiting protrusions 8 and the limiting grooves 9 are engaged with each other.

[0039] By having the first contact plane 3 and the second contact plane 4 fit together, the first joint connector 1 and the second joint connector 2 make movable contact. Then, through the cooperation of the fixing post 5 and the through hole 6, the second joint connector 2 and the first joint connector 1 can rotate movably. At the same time, under the restriction of the limiting structure, the first joint connector 1 and the second joint connector 2 are kept stable after rotating a certain angle. Subsequently, the other end of the first joint connector 1 and the second joint connector 2 is also provided with a movable connection structure to further increase the direction of joint movement, increase the joint movement angle, and improve the flexibility of the doll.

[0040] Among them, such as Figures 2-3 As shown:

[0041] The outer side of the limiting protrusion 8 is arc-shaped, and the inner wall of the limiting groove 9 is a smooth arc surface. The limiting protrusion 8 and the limiting groove 9 are arranged in a circular array around the center of the fixing post 5. The shape of the limiting protrusion 8 and the limiting groove 9 is defined to ensure that when the first joint connector 1 and the second joint connector 2 are rotated by external force, the limiting protrusion 8 can be moved out of the limiting groove 9 more easily for rotational adjustment. At the same time, the number of limiting protrusion 8 and limiting groove 9 is the same, n. So after each rotation of 360 / n°, the first joint connector 1 and the second joint connector 2 can remain relatively stable.

[0042] Example 2

[0043] like Figure 4 The joint connection structure of the doll toy shown includes:

[0044] First joint connector 1 and second joint connector 2;

[0045] A first contact plane 3 is provided on the side of one end of the first joint connector 1, and a second contact plane 4 is provided on the side of one end of the second joint connector 2. A fixing post 5 is fixed at the center of the second contact plane 4. A through hole 6 is provided on the first joint connector 1, and one end of the through hole 6 is located at the center of the first contact plane 3. The end of the fixing post 5 away from the second joint connector 2 passes through the through hole 6 and is provided with a limiting ring 7. A countersunk hole 10 is provided on the side of the first joint connector 1 away from the first contact plane 3. The limiting ring 7 is located in the countersunk hole 10. The end of the limiting ring 7 away from the fixing post 5 is smoothly connected to the outer side of the first joint connector 1. A limiting structure is also provided between the first joint connector 1 and the second joint connector 2. The limiting structure includes multiple sets of limiting protrusions 8 provided on the first contact plane 3 and multiple sets of limiting grooves 9 provided on the second contact plane 4. The limiting protrusions 8 and the limiting grooves 9 are engaged with each other.

[0046] The first joint connector 1 and the second joint connector 2 are respectively provided with movable connection structures at the ends away from the contact. The movable connection structure includes an annular groove 11 opened on the outer side of one end of the first joint connector 1, and one end of the second joint connector 2 is spherical.

[0047] By designing one end of the second joint connector 2 as a spherical structure, the second joint connector 2 can be more flexible and versatile when connected with other parts of the doll, and the direction adjustment can be more flexible.

[0048] The outer side of the limiting protrusion 8 is arc-shaped, and the inner wall of the limiting groove 9 is a smooth arc surface. Both the limiting protrusion 8 and the limiting groove 9 are arranged in a ring array around the center of the fixing post 5.

[0049] In practical use, the first joint connector 1 and the second joint connector 2 are connected to the two parts of the doll respectively. When it is necessary to rotate the joint, rotate the first joint connector 1 or the second joint connector 2. The limiting protrusion 8 is squeezed out of the limiting groove 9 under force. Then the first joint connector 1 and the second joint connector 2 rotate relative to each other. When the rotation angle reaches 360 / n° (n is the number of limiting protrusions 8 or limiting grooves 9), the limiting protrusion 8 is locked in the limiting groove 9 again, so that the first joint connector 1 and the second joint connector 2 remain relatively stable.

[0050] Example 3

[0051] like Figures 5-7 As shown, the difference from Embodiment 1 is that the fixing post 5 is fixed between two sets of second contact planes 4, and the first joint connector 1 is sleeved on the fixing post 5. The joint structure is stabilized by the friction between the first contact plane 3 and the second contact plane 4.

[0052] Example 4

[0053] like Figures 8-12 As shown, the difference from Embodiment 3 is that a transition joint connector 12 is added between the first joint connector 1 and the second joint connector 2, which is movably connected to the first joint connector 1 and the second joint connector 2 respectively. The connection method is the same as that in Embodiment 3.

[0054] Choose different types of joint connection structures to use depending on the type of doll.
