[0022] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0024] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0025] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0026] This embodiment provides a movable joint for a model toy, which includes a head, neck, torso, and limbs forming the main body. In this embodiment, a human figure model is used as an example of a model toy, but this is not intended to limit the scope of the invention. The movable joint of this invention can be applied to various model toys, including but not limited to people, animals, and robots.

[0027] Movable joints can serve as movable connection structures between the head and neck, between the neck and torso, between the limbs and torso, and between any joint portion of the limbs, such as the elbow and knee joints. In this embodiment, the knee joint of the leg of the doll model is used as an example for illustration, but this does not limit the purpose of this utility model. The movable joints to be protected by this utility model can be used in the same way for other parts of the doll model mentioned above and other connection parts of various types of model toys not mentioned.

[0028] Specifically, refer to Figures 1 to 4 The movable joint includes a first body 1, a second body 2, and a connecting component. The first body 1 is the thigh, the second body 2 is the lower leg, and the connecting component is the knee joint. In other embodiments, the first body 1 and the second body 2 can be the head and neck, the neck and torso, the limbs and torso, etc. A first connecting ring 11 is provided at one end of the first body 1, and a second connecting ring 21 is provided at one end of the second body 2. Both the first connecting ring 11 and the second connecting ring 21 are hollow annular structures. By setting the inner and outer diameters of the first connecting ring 11 and the second connecting ring 21, the first connecting ring 11 and the second connecting ring 21 are coaxially inserted and fitted, so that the outer circumference of the first connecting ring 11 fits with the inner circumference of the second connecting ring 21, or the inner circumference of the first connecting ring 11 fits with the outer circumference of the second connecting ring 21. When connected, the first body 1 and the second body 2 can rotate relative to each other around the axis of the two connecting rings, so that they have mobility and directly form the movable joint.

[0029] The connecting assembly includes an axial limiting member and a rotation limiting member 33. The axial limiting member includes a first axial locking member 31 and a second axial locking member 32. The first axial locking member 31 is coaxially inserted into the inner circumference of the first connecting ring 11 or the second connecting ring 21 along one side of the axial end (depending on the inner diameter of the first connecting ring 11 and the second connecting ring 21, the first axial locking member 31 is inserted into the connecting ring with the smaller inner diameter). The second axial locking member 32 is coaxially inserted into the first axial locking member 31 along the other side of the axial end, forming a pin-type fixed connection. The first axial locking member 31 and the second axial locking member 32 respectively abut against the axial ends of the first connecting ring 11 and the second connecting ring 21, forming an axial limit to ensure that the first body 1 and the second body 2 will not easily loosen or even detach in the axial direction.

[0030] The first connecting ring 11 and the second connecting ring 21 are clearance fit or interference fit. Under the action of the axial limiting component, the tightness of their fit does not affect the relative rotation of the first body 1 and the second body 2. When the first body or the second body is subjected to lateral force, the double connecting ring sleeve will make the inner and outer circumferences of the two fit tightly together, so as to effectively prevent the connection part from loosening. Under repeated adjustment, it can maintain good structural strength and durability.

[0031] The rotation limiting member 33 is disposed on the outer shaft end of the first connecting ring 11 or the outer shaft end of the second connecting ring 21. The rotation limiting member 33 can form a fixed connection with the first shaft locking member 31 or the second shaft locking member 32. (Refer to...) Figure 5 and Figure 6 The first main body 1 and the rotation limiting member 33 are respectively provided with a first limiting arc groove 41 and a first limiting post 42 that cooperate with each other. The second main body 2 and the rotation limiting member 33 are respectively provided with a second limiting arc groove 43 and a second limiting post 44 that cooperate with each other. The first limiting arc groove 41 and the second limiting arc groove 43 are both arranged in an arc structure with the axis of the connecting ring as the center. The first limiting post 42 moves within the length range of the first limiting arc groove 41, and the second limiting post 44 moves within the length range of the second limiting arc groove 43, thereby limiting the rotation range of the first main body 1 relative to the rotation limiting member 33 and the rotation range of the second main body 2 relative to the rotation limiting member 33, so as to facilitate the user to limit the range of motion of the first main body 1 and the second main body 2.

[0032] Furthermore, it also includes an adjusting latch 35, a locking pin 34 protruding from the rotation limiting member 33, a through hole 351 in the middle of the adjusting latch 35, and a locking block 341 protruding radially from the locking pin 34. When the adjusting latch 35 and the locking pin 34 are at a set angle, the locking pin 34 and the locking block 341 can pass through the through hole 351 simultaneously along their axial direction. After the locking pin 34 and the locking block 341 pass through the through hole 351, they rotate relative to each other, allowing the adjusting latch 35 and the locking pin 34 to rotate. When the angle is such that the two are at an angle other than the set angle, the locking block 341 abuts against the adjusting latch 35, and the locking pin 34 and the adjusting latch 35 cannot be disengaged axially. Furthermore, the adjusting latch 35 is also provided with multiple slots 352, which are located on the outer periphery of the locking pin 34 and distributed along a circular array. The locking block 341 can be engaged in any one of the slots 352 to maintain the adjusting latch 35 and the locking pin 34 at the corresponding relative angular positions.

[0033] One end of the adjusting latch 35 is detachably fixedly connected to a decorative piece 36. The decorative piece 36 is disposed on the rotational plane of the first body 1 and the second body 2, and is located at the front end of the two connecting rings between the first body 1 and the second body 2. This allows the decorative piece 36 to provide a covering and decorative effect on the connection part between the first body 1 and the second body 2, making the overall appearance more natural. Furthermore, when the user adjusts the first body 1 and / or the second body 2 to various angle positions, the relative angle between the adjusting latch 35 and the locking post 34 can be set to adjust the position of the decorative piece 36 to a suitable covering and decorative angle, thereby further increasing the adjustability of the user's view of the movable joint. In addition, the decorative piece 36 has baffles on both sides located on the axial sides of the first body 1 and the second body 2, which improves the covering and decorative effect while further improving the axial stability of the movable joint.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
