AI Technical Summary
The existing dolls have limited ranges of movement on the legs and spans, and cannot effectively simulate the range of movement of the human body, resulting in poor feel when performing front and back high legs and flat horses.
A doll leg and span automatic joint is designed, adopting a three-way ball joint and a ball axis structure, and is connected to the three-way ball joint and axle bowl through the front and rear ends of the ball axis, achieving range movement in the three-axis direction of the legs.
The design greatly improves the movement space of the doll's legs, allowing it to truly restore the range of movement of the human body, easily complete the front and back high legs, flat horse and other movements, improving the natural feeling and feel of the movement.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dolls, in particular to an automatic joint for the legs and crotch of a doll. Background Art
[0002] Compared with 12-inch doll (soldiers), 6-7-inch small-scale dolls have much higher requirements for playability, so there are higher requirements for the range of motion of the doll joints and the feel when changing the action. However, the range of motion of the doll's legs and hips is currently limited, and it is impossible to simulate the range of motion of the human body for design. For this reason, we proposed an automatic joint for the doll's legs and hips. Utility Model Content
[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a doll with automatic leg and crotch joints, which can truly restore the range of human activities and easily restore movements such as front and back high leg raises and splits.
[0004] The utility model provides the following technical solution: an automatic joint for legs and crotch of a puppet, comprising a crotch component and two leg components, wherein the crotch component is connected to the two leg components through an automatic joint, and the two leg components and the crotch component are movable;
[0005] The automatic joint includes a three-way ball joint installed inside the span component and two ball shafts for connecting the three-way ball joint. The leg component is installed inside the thigh joint, and the thigh joint is installed with a shaft cup for connecting the ball shaft.
[0006] The ball shaft comprises a shaft sleeve sliding with one of the three-way ball joints and a steering ball sliding with the shaft bowl, and an arc rod is connected between the shaft sleeve and the steering ball.
[0007] Preferably, the thigh joint is separated from the middle and spliced together, and the top of the thigh joint is bowl-shaped, and the ball shaft can move on the thigh joint through the shaft bowl.
[0008] Preferably, the three-way ball joint is designed in a cross shape, and the two ball axes are symmetrically distributed on the two ball joints of the three-way ball joint.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] The puppet's legs and hips have automatic joints, which are connected to the three-way ball joints and the shaft cups at the front and rear ends of the ball shaft respectively, realizing a range of movement of the legs in three axes, simulating the movement of human legs and greatly improving the leg movement space. Movements such as front and rear high leg raises and splits can be easily reproduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the figure: 1, span component; 2, leg component; 3, automatic joint; 31, three-way ball joint; 32, ball shaft; 321, bushing; 322, steering ball; 323, arc rod; 33, thigh joint; 34, shaft cup. DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.
[0016] See also Figure 1-3 , an automatic joint for legs and hips of a puppet, comprising a hip part 1 and two leg parts 2, wherein the hip part 1 is connected to the two leg parts 2 through an automatic joint 3, and the two leg parts 2 and the hip part 1 are movable;
[0017] The automatic joint 3 includes a three-way ball joint 31 installed inside the cross-component 1 and two ball shafts 32 for connecting the three-way ball joint 31. The three-way ball joint 31 is designed in a cross shape, and the two ball shafts 32 are symmetrically distributed on the two ball joints of the three-way ball joint 31. The two ball shafts 32 can move in three dimensions on the three-way ball joint 31.
[0018] The leg part 2 is installed in a thigh joint 33, and a shaft bowl 34 for connecting the ball shaft 32 is installed in the thigh joint 33. The thigh joint 33 is separated from the middle and spliced, and the top of the thigh joint 33 is bowl-shaped, and the ball shaft 32 can move on the thigh joint 33 through the shaft bowl 34. The ball shaft 32 moves on the shaft bowl 34, thereby further improving the range of motion of the leg part 2.
[0019] The ball shaft 32 includes a shaft sleeve 321 that slides with one of the ball joints in the three-way ball joint 31 and a steering ball 322 that slides with the shaft bowl 34. An arc rod 323 is connected between the shaft sleeve 321 and the steering ball 322. The front and rear ends of the ball shaft 32 are respectively connected to the three-way ball joint 31 and the shaft bowl 34, thereby realizing a range of movement of the legs in three axes, simulating the movement of human legs, and greatly improving the movement space of the legs. Movements such as front and rear high leg raises and splits can be easily restored.
[0020] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
