[0002] To achieve a high degree of realism, various joints are designed into the toy, which enable a wide variety of poses and enhance the toy's fun factor.

Figure 11 , Figure 12 As shown, the joint clamping force is provided by the inverted buckle 12 at the top of the pivot and the outer edge step 22 of the hole of the opponent. However, the torsional force is provided by the interference and pressing of multiple outward convex ribs with the opponent. During torsion, the ribs simultaneously squeeze and rub against the opponent. Due to the obvious undulation of the ribs, structural wear is likely to occur. After wear, the amount of squeezing interference decreases, resulting in a significant decrease in force, which affects the product life and customer experience. Utility Model Content

[0064] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0065] Example 1:

[0066] This utility model provides a jointed building block, such as Figures 1 to 10As shown, this is a three-joint assembly, including a first component 1, a second component 2, and a third component 3. The first component 1 has a first end and a second end, which are preferably integrally formed. The first end has a first shaft hole 13 and a plurality of arc-shaped pieces 14 arranged on one side of the first shaft hole 13 and circumferentially along the opening of the first shaft hole 13. The second component 2 has a third end and a fourth end, which are preferably integrally formed. The third end has a second shaft hole 23, and the third end can be assembled onto the first end to form a joint body, thereby allowing the plurality of arc-shaped pieces 14 to extend into the second shaft hole 23, with the outer surface of the arc-shaped pieces 14 fitting against the wall of the second shaft hole 23. Figure 2 , Figure 3 , Figure 10 As shown, the third component 3 can be assembled into the joint body to form a joint, and passes through the first shaft hole 13 and the second shaft hole 23 so that the first component 1 can rotate relative to the second component 2 and the third component 3 moves synchronously with the first component 1.

[0067] In this embodiment, the axes of the second and fourth ends are on the same plane. The second and fourth ends can be used to assemble other building blocks to form the shapes desired by the player. The second and fourth ends can be male or female, making assembly convenient and operation simple.

[0068] like Figure 1 As shown, the third component 3 has a first part 31, a second part 32, and a third part 33, which are connected in sequence. Preferably, the first part 31, the second part 32, and the third part 33 are integrally formed.

[0069] Furthermore, the first part 31 penetrates the first shaft hole 13, as shown below. Figure 2 , Figure 5 As shown, the first part 31 has a protrusion 311, and the hole wall of the first shaft hole 13 has a stepped structure or a groove, preferably a stepped structure, so that the first part 31 assembled into the first shaft hole 13 is allowed to detach from the first shaft hole 13 under the drive of external force, and the first part 31 is not allowed to leave the first shaft hole 13 in a natural state, which ensures the clamping force of the joint and improves the stability of the joint. At the same time, it can be disassembled and assembled at any time by hand force, which is fun.

[0070] like Figure 1As shown, the second part 32 penetrates the second shaft hole 23, and multiple convex blocks 321 extend circumferentially from the second part 32. A receiving groove is formed between two adjacent convex blocks 321. The arc-shaped piece 14 is assembled into the receiving groove, thereby preventing the first component 1 and the third component 3 from rotating relative to each other. The outer surface of the convex block 321 does not contact the hole wall of the second shaft hole 23. The inner surfaces of the multiple arc-shaped pieces 14 are all arc-shaped surfaces, and the cross-section of the arc-shaped piece 14 is fan-shaped. The outer circular surface of the four-lobed arc-shaped piece 14 is tightly fitted with the hole wall of the second shaft hole 23. The force of the tight fit comes from the interference of the third component 3 on the inner circle of the arc-shaped piece 14.

[0071] It should be noted that the second shaft hole 23 is a stepped through hole, and an inner edge step 231 is provided on the second shaft hole 23, such as... Figure 5 As shown, in the joint body, the end of the arc-shaped piece 14 abuts against the inner edge step 231, which can prompt the user to assemble the first component 1 and the second component 2 into place.

[0072] like Figure 1 As shown, the second component 2 has an outer edge step 22 at its end facing away from the first component 1. When the third component 3 is assembled into the joint body, the third part 33 is fastened onto the outer edge step 22, as shown. Figure 4 , Figure 5 As shown, the cross-section of the third part 33 is tangentially circular. The first component 1, the second component 2, and the third component 3, when assembled together, have a smooth outer surface when viewed externally, and the joints have a circular or elliptical structure, as shown. Figure 10 As shown.

[0073] This invention provides torsional force through the friction between four thin arc-shaped plates 14 and the wall of the second shaft hole 23. During torsional friction, the large area and smooth curvature of the four thin arc-shaped plates 14 result in uniform wear and greater wear resistance. At the same time, since the third component 3 does not slide relative to the torsion, the third component 3 itself will not wear, thus ensuring that the compressive force will not drop suddenly due to the wear of the arc-shaped plates 14, and can better maintain the torsional force. In addition, because the arc-shaped plates 14 have a large area, they can provide a large initial torque, resulting in a good user experience and enhancing the premium feel of the toy.

[0074] This utility model also provides a toy, including an articulated building block. When disassembling the articulated building block, the third component 3 can be pushed out by hand through the first shaft hole 13, and then the first component 1 and the second component 2 can be separated manually. This makes assembly simpler. After assembly, the clamping force is ensured by the protrusion 311 in combination with the step structure or groove, which has good stability and a beautiful appearance. All connecting parts are smoothly transitioned and can be directly assembled into a doll or animal without the need to add an outer armor, making it highly practical.

[0075] Example 2:

[0076] The difference between this embodiment and embodiment 1 is that the first part 31 has a stepped structure or a groove, and the hole wall of the first shaft hole 13 has a protrusion 311, which can also achieve the effect of this utility model.

[0077] Comparative example:

[0078] like Figure 8 , Figure 9 , Figure 10 As shown, this embodiment uses an interlocking joint structure, as... Figure 11 , Figure 12 , Figure 13 As shown in Table 1, the changes in torque and force values ​​compared to the three-joint in Example 1 are as follows:

[0079] Table 1:

[0080]

[0081] The experimental data above shows that, in terms of both torque value and the attenuation of torque value over multiple rotations, the three-joint has a significant advantage over the interlocking joint, which helps to extend the service life of the joint, improves the user experience, and greatly enhances the practicality of the toy.
