AI Technical Summary
After wearing the clothes, the joints of the existing dolls are not easy to maintain their posture due to the tension of the clothes, and their range of movement is limited, which affects playability.
The joint structure is adopted for extrusion springs, meshing teeth, tooth discs and rotating discs. The rotating disc is installed through the rotating shaft, and the meshing of the meshing teeth and tooth discs is combined with the extrusion effect of the extrusion spring to prevent the joint from rotating due to the tensile force of the clothes. At the same time, the friction is adjusted through the connecting rod and threaded nail to control the joint movement.
The stability and mobility of the joints are balanced in the dressing state, preventing the joints from rotating due to the stretching force of the clothes, and improving the playability and posture retention ability of the doll.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of doll joints, in particular to an adjustable joint. Background Art
[0002] Among existing children's toys, dolls in the shape of human figures are very popular among children due to their appearance close to that of humans, high playability and simulation, especially dolls that can wear clothes or imitate human limbs to move, which are especially popular among girls.
[0003] Among them, the "universal joint structure for assembled doll toys" disclosed in the announcement number "CN220834111U" has solved the problem that the existing joints are not firm and are easy to loosen, especially when the product size has some deviation or some wear / deformation, the problem of loosening is more obvious, that is, the product size has a small tolerance space and low tolerance rate, and therefore the parts processing precision requires high disadvantages. After further search, it was found that the "a building block doll with a new type of joint" disclosed in the announcement number "CN218106721U" has effectively solved the problem of different types of building block toys through a specific technical structure setting. The scenes involving dolls are also diverse. The dolls of current building block toys have the problem of limited range of movement of the hands and feet, which makes the dolls unable to be used in different occasions and restricts their playability. However, in actual use, dolls with similar structures still have many defects. For example, in existing doll toys, the joints are simply embedded in the torso. However, after the doll is dressed, the toughness and rebound brought by the clothes will cause the joints to move naturally due to the stretching of the clothes, and it is impossible to naturally maintain a good posture. Therefore, it is necessary to design an adjustable joint to solve the problems raised in the above background technology. Utility Model Content
[0004] The purpose of the present invention is to provide an adjustable joint to solve the problems raised in the above background technology.

[0008] Preferably, a compression spring is fixedly mounted on the inner side of the rotating disk, with one end of the compression spring contacting the inner side of the shoulder assembly. The compression spring can compress the rotating disk, thereby enabling better engagement between the meshing teeth mounted on the inner side of the rotating disk and the toothed disc, thereby increasing the resistance of the rotating disk during rotation, thereby preventing deformation of the joint caused by the stretching of clothing.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the utility model proposes an adjustable joint, including a toy body 1, a shoulder assembly 2 and an upper arm 3. The shoulder assemblies 2 are provided on both sides of the toy body 1. A rotating disk 201 is fixedly installed on the outside of the toy body 1. The rotating disk 201 is located on the inner side of the shoulder assembly 2. A mounting sleeve 206 is fixedly installed on the inner side of the shoulder assembly 2. A limit disk 207 is fixedly installed inside the mounting sleeve 206. A toothed disk 208 is installed inside the limit disk 207. A rotating disk 201 is rotatably installed inside the shoulder assembly 2 on one side of the mounting sleeve 206. The inner side of the rotating disk 201 is fixedly installed with a toothed disk 208. The toothed disc 208 is engaged with the meshing teeth 209, and the inner thread of the shoulder component 2 is installed with the rotating shaft 203, the rotating shaft 203 passes through the interior of the rotating disc 201 and is installed with the inner thread of the shoulder component 2, the bottom limit installation of the shoulder component 2 is provided with the upper arm 3, the interior of the upper arm 3 is movably provided with the lower arm 3, the bottom of the shoulder component 2 is fixedly installed with the connecting rod 204, the interior of the upper arm 3 is provided with a snap-fit groove 304 that cooperates with the connecting rod 204, the outer side of the toothed disc 208 is fixedly installed with a limiting block 210, and the interior of the limiting disc 207 is provided with a limiting groove 211 that cooperates with the limiting block 210.
[0023] The working principle of an adjustable joint based on the first embodiment is as follows: the rotating disk 201 is installed on the outside of the mounting sleeve 206 through the rotating shaft 203, the toothed disk 208 and the rotating disk 201 are in contact with each other, and the extrusion spring 205 is used to make the tooth groove on the toothed disk 208 mesh with the meshing teeth 209 on the inner side of the rotating disk 201. During the adjustment process of the shoulder joint, the meshing teeth 209 and the toothed disk 208 are engaged, so that the rotating disk 201 and the limit disk 207 are not easily rotated by the tensile force of the clothes 101. During the adjustment process of the joint, the toothed disk 208 and the meshing teeth 209 are engaged. The squeezing simultaneously squeezes the squeezing spring 205, causing the meshing teeth 209 to separate from the toothed disc 208, thereby making it easy to adjust the joint. The shoulder assembly 2 is connected to the upper arm 3 by limiting the mutual position between the connecting rod 204 and the engaging groove 304. During the rotation adjustment of the shoulder assembly 2, the upper arm 3 can be synchronously driven to flip, and the mounting seat 302 and the threaded nail 303 are threadedly matched. The friction between the mounting seat 302 and the upper arm 3 can be adjusted by rotating the threaded nail 303, which can effectively control the range of motion of the joint and make the joint adjustment process more convenient.
[0024] Example 2
[0025] like Figure 2 、 Figure 3 and Figure 5 As shown, the adjustable joint proposed by the present invention, compared with the first embodiment, this embodiment also includes: an extrusion spring 205 is fixedly installed on the inner side of the rotating disk 201, one end of the extrusion spring 205 is in contact with the inner side of the shoulder assembly 2, a mounting seat 302 is fixedly installed on the top of the lower arm 301, the mounting seat 302 and the upper arm 3 are movably installed by a screw 303, the rotating disk 201 and the toy body 1 are fixedly installed by the connecting seat 202, and clothes 101 are provided on the outside of the toy body 1.
[0026] In this embodiment, Figure 5 As shown, the rotating disk 201 can be squeezed by the squeezing spring 205, so that the meshing teeth 209 installed inside the rotating disk 201 can better mesh with the toothed disk 208, so that the rotating disk 201 has greater resistance during the rotation process, thereby preventing the joints from being deformed by the stretching of the clothes 101; Figure 3 As shown, the lower arm 301 and the upper arm 3 can be connected by the mounting base 302, which is more convenient during the adjustment process. At the same time, the mounting base 302 and the upper arm 3 are threadedly mounted by the screw 303, and the friction between the mounting base 302 and the upper arm 3 can be adjusted by rotating the screw 303; Figure 2As shown, the shoulder assembly 2 can be installed inside the toy body 1 through the connecting seat 202, and can be easily disassembled and assembled for maintenance during use. At the same time, the rotating disk 201 can link the shoulder assemblies 2 to flip during rotation, making it convenient to adjust the joints.
