[0026] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, a movable joint structure for a toy includes a first joint body 10 and a second joint body 20. The first joint body 10 includes a first joint portion 100, and a cylindrical protrusion 110 is provided at one end of the first joint portion 100. The second joint body 20 includes a second joint portion 200, and a connecting ring 210 is provided at one end of the second joint portion 200 near the first joint portion 100. The connecting ring 210 is sleeved on the protrusion 110, so that the second joint portion 200 can rotate along the circumferential direction of the protrusion 110.

[0027] In this embodiment, the assembly only requires attaching the sleeve ring 210 of the second joint portion 200 to the protrusion 110 of the first joint portion 100 to form a joint-like connection between the first joint body 10 and the second joint body 20. The overall structure is simple and the manufacturing cost is low.

[0028] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 2 As shown, the direction of the protrusion 110 is perpendicular to the direction of the first joint 100. When the sleeve ring 210 is sleeved on the protrusion 110 of the first joint 100, the first joint body 10 and the second joint body 20 can present a joint-like connection similar to that between the upper arm and forearm or the thigh and calf.

[0029] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 2 As shown, a clamping part 120 is provided on one side of the first joint portion 100. The clamping part 120 clamps and fixes the protrusion 110 from both ends. The sleeve ring 210 includes a first inner ring 211 and a first outer ring 212. A first ring wall 213 is formed between the first inner ring 211 and the first outer ring 212. When the sleeve ring 210 is sleeved on the protrusion 110, the protrusion 110 passes through the first inner ring 211, so that the second joint portion 200 can rotate along the circumferential direction of the protrusion 110.

[0030] In some embodiments, combined with Figure 1 and Figure 2 As shown, the first ring wall 213 is provided with a first limiting ring 213a facing outward. The first limiting ring 213a is disposed around the first inner ring 211. The clamping part 120 is provided with a first limiting groove 120a that cooperates with the first limiting ring 213a. When the sleeve ring 210 is sleeved on the protrusion 110, the first limiting ring 213a is engaged in the first limiting groove 120a. Thus, when the first inner ring 211 rotates along the circumferential direction of the protrusion 110, it can better guide the rotation direction of the first inner ring 211. It should be noted that the inner side of the clamping part 120 mentioned here refers to the opposite side of the clamping part 120.

[0031] In some embodiments, combined with Figure 1 and Figure 2 As shown, the first joint portion 100 forms a first arc surface 130 on the side near the protrusion 110. When the sleeve ring 210 is sleeved on the protrusion 110, the first outer ring 212 will rotate between the protrusion 110 and the first arc surface 130, thus preventing the sidewall of the first joint portion 100 from interfering with the rotation of the first outer ring 212.

[0032] This application also provides a second embodiment, combined with... Figure 3 and Figure 4 As shown, the difference from the first embodiment is that a connecting portion 140 is provided on one side of the first joint portion 100, the protrusion 110 is provided on the side wall of the connecting portion 140, the sleeve ring 210 includes a second inner ring 214 and a second outer ring 215, and a second ring wall 216 is formed between the second inner ring 214 and the second outer ring 215. When the sleeve ring 210 is sleeved on the protrusion 110, the protrusion 110 passes through the second inner ring 214 and the second ring wall 216 fits against the connecting portion 140, so that the second joint portion 200 can rotate along the circumferential direction of the protrusion 110.

[0033] In some embodiments, combined with Figure 3 and Figure 4 As shown, on the side of the protrusion 110 away from the connecting part 140, a second limiting ring 111 is provided. On the inner wall of the second inner ring 214, a second limiting groove 214a is provided to cooperate with the second limiting ring 111. When the sleeve ring 210 is sleeved on the protrusion 110, the second limiting ring 111 is engaged in the second limiting groove 214a. In this way, the connecting part 140 clamps and fixes the protrusion 110 from both ends.

[0034] In some embodiments, combined with Figure 3 and Figure 4 As shown, a third limiting ring 214b is provided on the inner wall of the second inner ring 214, and a third limiting groove 112 that cooperates with the third limiting ring 214b is provided on the circumferential surface of the protrusion 110. When the sleeve ring 210 is sleeved on the protrusion 110, the third limiting ring 214b is engaged in the third limiting groove 112. Thus, when the second inner ring 214 rotates along the circumferential direction of the protrusion 110, it can better guide the rotation direction of the second inner ring 214.

[0035] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
