[0002] Building block toys play a significant role in children's intellectual development, improving hand-eye coordination and fostering their intelligence and imagination. Many building block toys utilize a ball-and-socket joint structure, resulting in a simple structure and flexible, varied movements. This achieves the desired joint function, adding to the toy's realism and playfulness.
[0003] Currently, the joint structure of the ball head and ball socket mostly relies on the ball head and ball socket structure itself to achieve the movement limit, such as Figure 3 、 Figure 4 As shown, the joint structure of the ball head and the ball socket will experience force attenuation during use, which will cause the upper arm to droop downward, as if the shoulder is dislocated, reducing the visual simulation of the joint. Therefore, it is urgent to design a new structure to solve the above problem. Utility Model Content

[0006] The second building structure can be matched and spliced into the first building structure and the functional body extends into the limiting structure connected to the first building structure so that:
[0007] When the second building structure moves relative to the first building structure, the limiting structure can limit the functional body and thus limit the range of movement of the second building structure in the first building structure.

[0025] The utility model realizes the joint function through the first building block and the second building block that cooperate with each other.

[0040] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.
[0041] Example 1:
[0042] The utility model provides a building block joint structure, including a first building block 1 and a second building block 2, the first building block 1 has a first assembling structure 11, the second building block 2 has a second assembling structure 21, a functional body 211 extends from the end of the second assembling structure 21, the second assembling structure 21 can be matched and spliced into the first assembling structure 11, and the functional body 211 extends into a limiting structure 111 connected to the first assembling structure 11, when the second assembling structure 21 moves relative to the first assembling structure 11, the limiting structure 111 can limit the functional body 211, thereby limiting the range of movement of the second assembling structure 21 in the first assembling structure 11.
[0043] Specifically, take the building block joint structure applied to the shoulder joint of a doll toy as an example. Figure 1 、 Figure 2 As shown, the second building structure 21 moves relative to the first building structure 11. The movement here can be just rotation, or it can be a combined movement of rotation and movement of the second building structure 21 away from the center of the first building structure 11 to achieve more realistic simulation action.
[0044] Specifically, the second building structure 21 is a ball head structure, and the first building structure 11 is a ball socket structure. The opening of the ball socket structure is smaller than the outer diameter of the ball head structure, and the ball head structure can enter the interior of the ball socket structure under the force of the hand, so that the ball socket structure has a limiting effect on the ball head structure in a natural state. It should be noted that in the present invention, the axis point corresponding to the end of the second building block 2 away from the second building structure 21 (corresponding to Figure 2 When the A point in the figure is rotated to the lowest point, it is still higher than the axis point corresponding to the second building structure 21 (corresponding to Figure 2 Point B in the figure), point A is defined as the first axis point, point B is defined as the second axis point, and the angle between the line AB and the vertical direction is preferably an acute angle, and the value range of the acute angle is preferably 15° to 75°, for example, the acute angle is 30°, 45°, 60°, 70°, etc. That is, after the second building block 2 is assembled into the first building block 1, when point A is at the lowest point, the second building block 2 is still in the posture of being inserted obliquely downward into the first building block 1, that is, the joint of the entire shoulder presents a visual appearance of being obliquely upward and convex. In addition, due to the gravity of the arm, this design ensures that the second building block 2 always has the force to be inserted downward into the first building block 1, and the second building block 2 is not easy to fall out of the first building block 1. During the structural design, not only does it not need to consider the anti-slip structure of the ball socket opening, which reduces the difficulty of structural design, but also increases the stability of the toy structure and the visual simulation. At the same time, by adjusting the size of the angle between the AB line and the vertical direction, the character shape with different width or narrow shoulders can be displayed. When the angle between the AB line and the vertical direction is larger, the doll shape with wider shoulders is displayed; when the angle between the AB line and the vertical direction is smaller, the doll shape with narrower shoulders is displayed.
[0045] Specifically, the functional body 211 is preferably a columnar structure, and the limiting structure 111 is a limiting hole, for example, a circular hole, etc. In practical applications, the functional body 211 and the second assembly structure 21 are an integrally formed structure or a structure formed by splicing one or more parts.
[0046] In practical applications, the axis of the functional body 211 and the axis of the second building block 2 can be arranged coaxially, such as Figure 2 However, in some special application scenarios, in order to match the structural characteristics of the toy, the axis of the functional body 211 and the axis of the second building block 2 can also be set to form an angle structure to prevent it from falling out. The angle is defined as θ, and the value range of θ is preferably greater than or equal to 90° and less than 180°, such as 90°, 145°, 155°, etc.
[0047] In this embodiment, Figure 1 As shown, the middle of the second building block 2 is a rotatable structure, and the second building block 2 is an integrally formed joint structure, which makes its own stability better.
[0048] The present invention also provides a toy including a building block joint structure. In practical applications, the toy can be an animal toy, a puppet toy, or a science fiction character toy. For example, in the case of a puppet toy, the building block joint structure can be arranged at any one or more joints of the puppet. For example, the building block joint structure can be arranged at the puppet's shoulder joint. In another example, the building block joint structure can be arranged at the puppet's hip joint. In another example, the building block joint structure can be arranged at the puppet's waist joint.
[0049] Example 2:
[0050] This embodiment differs from Embodiment 1 in that the second building block 2 further has a splicing end, which is preferably arranged at an end away from the second building structure 21. The splicing end is provided with a third splicing structure 22, which can be spliced with other building blocks to form a specific shape, such as the splicing end splicing the upper arm 3 of a doll. Specifically, the third splicing structure 22 can be designed as a male head or a female head, thereby increasing the fun of the toy.
[0051] The working principle of this utility model is as follows:
[0052] The first building block 1 and the second building block 2 are spliced together, the second building structure 21 is spliced on the first building structure 11, and the functional body 211 is spliced into the limiting structure 111. When the second building structure 21 rotates relative to the first building structure 11, one side of the functional body 211 contacts the inner wall of the limiting structure 111 and is blocked by the limiting structure. At this time, the functional body 211 cannot rotate relative to the limiting structure 111 along the original direction and is thus limited. Therefore, the rotation of the second building structure 21 relative to the first building structure 11 along the original direction is also limited, and then the matching structure of the functional body 211 and the limiting structure 111 can play a role in limiting the range of movement of the second building structure 21 in the first building structure 11.
