The first component comprises a first rotating shaft and a first connector, while the second component comprises a second rotating shaft and a second connector. The first connector and the second connector are rotatably connected, allowing the first and second components to rotate relative to each other. However, in this patent document, the rotating shaft of either component is too close to the connector of the other component, which is not conducive to product molding. Utility Model Content

[0004] The utility model provides a movable joint structure and a toy, which can avoid the adhesion of a first component and a second component by means of a reserved beer inlay groove, thereby facilitating product molding.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] According to the first aspect of the utility model, an embodiment of the utility model provides a movable joint structure, including a first component and a second component, the first component includes a first rotating shaft and a first connecting head connected to one end of the first rotating shaft, the second component includes a second rotating shaft and a second connecting head connected to one end of the second rotating shaft, the first connecting head and the second connecting head are rotatably connected; beer inlay grooves are provided between the first rotating shaft and the second connecting head and between the second rotating shaft and the first connecting head.

[0026] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0027] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0029] The embodiment of the present invention provides a movable joint structure, such as Figure 1-4As shown, the first component 100 and the second component 200 are shown. The first component 100 includes a first rotating shaft 110 and a first connector 120 connected to one end of the first rotating shaft 110. The first connector 120 can be connected to a portion of the end surface of the first rotating shaft 110, leaving a remaining portion of the end surface of the first rotating shaft 110 near the first connector 120. The second component 200 includes a second rotating shaft 210 and a second connector 220 connected to one end of the second rotating shaft 210. The second connector 220 can be connected to a portion of the end surface of the second rotating shaft 210, leaving a remaining portion of the end surface of the second rotating shaft 210 near the second connector 220. The first connector 120 and the second connector 220 are rotatably connected, allowing the first component 100 and the second component 200 to rotate relative to each other. A beer trough 300 is provided between the first rotating shaft 110 and the second connector 220, and between the second rotating shaft 210 and the first connector 120.

[0030] Since the movable joint structure of this embodiment is primarily formed by secondary injection molding, that is, one of the first component 100 and the second component 200 is first molded, then the first molded component is placed in the secondary molding mold, and the other of the first component 100 and the second component 200 is secondary injection molded, thereby completing the molding of the entire product. In this embodiment, beer insertion grooves 300 are provided between the first rotating shaft 110 and the second connecting head 220, and between the second rotating shaft 210 and the first connecting head 120. Specifically, the beer insertion grooves 300 can be formed by beer insertion parts of the secondary molding mold. In this way, during the secondary injection molding of the product, adhesion between the first rotating shaft 110 and the second connecting head 220, and between the second rotating shaft 210 and the first connecting head 120 will not occur, thereby facilitating product molding. After molding, the first component 100 and the second component 200 can rotate relative to each other.

[0031] At the same time, the presence of the beer groove 300 prevents interference between the first rotating shaft 110 and the second connecting head 220 and between the second rotating shaft 210 and the first connecting head 120. When the first component 100 and the second component 200 rotate relative to each other, the friction of the rotation can be reduced, making the relative rotation of the first component 100 and the second component 200 smoother.

[0032] In some embodiments, the end surface of the first rotating shaft 110 near the first connector 120 and the end surface of the second rotating shaft 210 near the second connector 220 are both configured as outwardly inclined arcuate surfaces 301. In the direction upward away from the first connector 120, the arcuate surface 301 of the first rotating shaft 110 gradually moves away from the first connector 120, and in the direction downward away from the second connector 220, the arcuate surface 301 of the second rotating shaft 210 gradually moves away from the second connector 220. Beer grooves 300 are formed between the arcuate surface 301 of the first rotating shaft 110 and the second connector 220, and between the arcuate surface 301 of the second rotating shaft 120 and the first connector 120.

[0033] This structure makes the opening of the beer trough 300 larger, and interference is less likely to occur between the first rotating shaft 110 and the second connecting head 220 as well as between the second rotating shaft 210 and the first connecting head 120, and the arc surface 301 can adapt to the shapes of the first connecting head 120 and the second connecting head 220.

[0034] In some embodiments, a first clamping joint 410 for clamping and fixing the first rotating shaft 110 is provided at one end of the first rotating shaft 110 away from the first connector 120, and a second clamping joint 420 for clamping and fixing the second rotating shaft 210 is provided at one end of the second rotating shaft 210 away from the second connector 220. The first clamping joint 410 and the second clamping joint 420 can be respectively clamped into corresponding clamping holes, thereby achieving rapid installation of the first rotating shaft 110 and the second rotating shaft 210 and facilitating removal of the first rotating shaft 110 and the second rotating shaft 210 from their installed positions.

[0035] Furthermore, the first clamping joint 410 includes a first protruding ring 411 and a first truncated cone portion 412 connected to the first protruding ring 411. The outer diameter of the first protruding ring 411 is larger than the outer diameter of the first rotating shaft 110. After being engaged with the engaging hole, the first protruding ring 411 can prevent the first rotating shaft 110 from being dislodged from the engaging hole, thereby securing the first rotating shaft 110. The outer diameter of the first truncated cone portion 412 gradually decreases as it extends outward, resulting in a truncated cone shape. This facilitates insertion of the first clamping joint 410 into the engaging hole.

[0036] The second clamping joint 420 includes a second protruding ring 421 and a second truncated cone portion 422 connected to the second protruding ring 421. The outer diameter of the second protruding ring 421 is larger than the outer diameter of the second rotating shaft 210. After being engaged with the engaging hole, the second protruding ring 421 can prevent the second rotating shaft 210 from being dislodged from the engaging hole, thereby securing the second rotating shaft 210. The outer diameter of the second truncated cone portion 422 gradually decreases as it extends outward, forming a truncated cone shape. This facilitates insertion of the second clamping joint 420 into the engaging hole.

[0037] Furthermore, the first end surface 413 of the first protruding ring 411, which is close to the first connector 120, is perpendicular to the axial direction of the first rotating shaft 110, and the second end surface 423 of the second protruding ring 421, which is close to the second connector 220, is perpendicular to the axial direction of the second rotating shaft 120. This makes the end surfaces of the first and second protruding rings 411, 421 smooth, and the first protruding ring 411 can further prevent the first rotating shaft 110 from escaping from the engaging hole, and the second protruding ring 421 can further prevent the second rotating shaft 210 from escaping from the engaging hole, thereby improving the effectiveness of the engaging and fixing.

[0038] In some embodiments, the first connector 120 and the second connector 220 are both hemispherical, and the diameter of the first connector 120 is slightly larger than the diameter of the second connector 220. The specific diameters of the first connector 120 and the second connector 220 are determined by those skilled in the art based on actual needs. Due to the presence of the beer trough 300, the first connector 120 and the second connector 220 are both closer to a standard hemispherical shape.

[0039] In some embodiments, a rotating shaft 130 is provided on the first connector 120, and a rotating hole 230 adapted to the rotating shaft 130 is provided on the second connector 220. The rotating shaft 130 is provided in the rotating hole 230 and can rotate in the rotating hole 230 to realize the rotating connection between the first connector 120 and the second connector 220.

[0040] In some embodiments, the first rotating shaft 110, the first connecting head 120, the rotating shaft 130 and the first clamping joint 410 of the above embodiment can be integrally formed, and the second rotating shaft 210, the second connecting head 220 and the second clamping joint 420 can be integrally formed, so as to facilitate the manufacturing and molding of the first component 100 and the second component 200, and to enhance the connection strength between each other.

[0041] An embodiment of the present invention further provides a toy, comprising the movable joint structure of any of the above embodiments. For detailed description of the movable joint structure, reference may be made to the above embodiments and will not be repeated here.

[0042] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
