Description

Universal joint structure of assembled doll toy

Technical Field

The utility model belongs to the technical field of toys, and particularly relates to a universal joint structure of an assembled doll toy.

Background

In order to develop the practical ability of infants and develop the space imagination and intelligence of infants, various DIY-assembled toys, such as assembled puppet toys, are designed. The assembled doll toy is characterized in that the doll toy is divided into a plurality of movable and detachable parts, and in the playing process, the dispersed parts are assembled into a complete doll model by infants. In order to adjust the shape or form of the assembled doll toy and make the doll toy more similar to a real human body, some joint parts of the doll toy need to be designed into universal joint structures capable of rotating in multiple dimensions.

The common universal joint structure of assembled puppet comprises a first rotating part and a second rotating part, wherein the first rotating part comprises a first rotating part body and a universal ball which are connected together, the second rotating part is provided with a spherical hole for embedding the universal ball, the depth of the spherical hole is slightly larger than the radius of the universal ball, and the inner diameter of the hole edge of the spherical hole is slightly smaller than the diameter of the universal ball. When the universal ball of the first rotating member is assembled, the universal ball is embedded into the spherical hole of the second rotating member, and then the universal ball is clamped in the spherical hole to form a universal joint.

However, the universal joint structure of the assembled doll toy has the following problems: if the difference between the diameter of the hole edge of the spherical hole and the diameter of the universal ball is large, the hole edge of the spherical hole needs to be greatly and forcefully expanded in the process of embedding the universal ball, so that the embedding action is hard, and particularly, the embedding action is difficult for young children with small strength. On the contrary, if the difference between the diameter of the hole edge of the spherical hole and the diameter of the universal ball is smaller, although the embedding action is not too hard in the assembling process, the embedding is not firm and is easy to loosen, especially when the product size is slightly deviated or is worn/deformed, the problem of quick loosening is more obvious, namely the fault-tolerant space of the product size is small, the fault-tolerant rate is low, and therefore, the requirement on the machining precision of the parts is high.

Disclosure of utility model

The utility model aims to overcome the defects and provide the universal joint structure of the assembled doll toy, which has the advantages that the embedding action of the universal ball in the assembling process is labor-saving, the universal ball is not easy to loose after being embedded, and in addition, the requirement on the processing precision of parts is low.

The aim can be achieved according to the following scheme: the utility model provides a assemble universal joint structure of doll toy, includes first rotation piece and second rotation piece, and first rotation piece is including linking together first rotation piece main part and universal ball, and the second rotates the piece and is equipped with the spherical hole that supplies the universal ball embedding, and the hole in spherical hole is less than the diameter of universal ball along the diameter, its characterized in that: the universal ball is provided with a deformation groove, the depth of the deformation groove is larger than the radius of the universal ball, the opening direction of the deformation groove is opposite to the main body of the first rotating member, and the position of the spherical center point of the universal ball is positioned in the groove cavity of the deformation groove; the inside of the deformation groove is also provided with a supporting block, and the supporting block is positioned at one end, far away from the main body of the first rotating piece, of the groove cavity of the deformation groove.

More preferably, the universal ball is symmetrically formed with two sphere-segment planes which are parallel to each other and perpendicular to the plane of the groove wall of the deformation groove.

The term "segment plane" refers to a plane formed by cutting an edge portion of a sphere (corresponding to a truncated crown portion) by a plane.

The utility model has the following advantages and effects:

The central area of the spherical center of the universal ball is positioned in the groove cavity of the deformation groove, the supporting block is positioned at one end, far away from the main body of the first rotating member, of the groove cavity of the deformation groove (namely, the supporting block is close to the notch part of the deformation groove), so that the middle part of the universal ball (the middle part along the embedding direction) can collapse and deform after being pressed, when the middle part of the universal ball reaches the edge part of the spherical hole of the second rotating member in the process of embedding the universal ball into the spherical hole, the middle part of the universal ball can temporarily collapse and deform, the width of the deformation groove is temporarily narrowed (except the part close to the supporting block), the spherical hole edge of the second rotating member basically does not need to be expanded or has smaller expansion amplitude, and the circumference of the spherical Kong Kongyan basically does not need to be stretched or has smaller stretching amplitude, so that the embedding action in the assembling process is relatively easy and labor is relatively saved; furthermore, the sphere of the universal ball is symmetrically formed with two sphere-segment planes, namely, the sphere of the universal ball is in a sphere-segment shape, so that the action of embedding the spherical hole is relatively easy and relatively labor-saving (compared with the embedding action of a pure spherical sphere with the same diameter). After the embedding is completed, the universal ball is restored to the original state, and the diameter of the hole edge of the spherical hole is smaller than that of the universal ball, so that the universal ball is firm after the embedding and is not easy to loosen.

Furthermore, because the embedding action in the assembling process is relatively labor-saving and easy, the hole edge of the spherical hole does not need to be greatly and forcedly expanded in the embedding process, and therefore, the difference between the hole edge diameter of the spherical hole and the diameter of the universal ball can be designed to be relatively larger; in other words, under the precondition that the force required by the embedding action is the same, compared with the traditional structure, the difference between the diameter of the universal ball and the diameter of the spherical hole edge can be designed to be larger; therefore, even if the product size is slightly deviated or worn or deformed, the product cannot be loosened easily, namely the product size has large fault-tolerant space and high fault-tolerant rate, the problems of small fault-tolerant space and low fault-tolerant rate of the product size in the traditional structure are solved, and the part machining precision requirement is greatly reduced.
