referring first to FIG. 1, the present invention provides a rotational positioning apparatus 1 for mounting within an item of jewelry 2, wherein the item of jewelry 2 generally comprises a first portion 21 and a second portion 22, the first portion 21 being a first shape of the item of jewelry and the second portion 22 being a second shape of the item of jewelry; alternatively, and in reverse, first portion 21 may be a second configuration of the item of jewellery and second portion 22 may be a first configuration of the item of jewellery. More specifically, the first portion 21 or first figure may be a body portion of a doll, and the second portion 22 or second figure may be a head portion of a doll; the fixed member 11 and the rotating member 12 of the rotational positioning apparatus 1 are respectively mounted on the first portion 21 and the second portion 22. The utility model utilizes the rotary positioning device 1 to make the first part 21 and the second part 22 rotate relatively; that is, the head of the doll may be rotated relative to the body portion to adjust the angle.

As shown in FIGS. 2 and 3, the rotary positioning device 1 for jewelry articles according to the present invention may comprise: a fixed part 11, a rotating part 12 and a limiting part 13. Wherein the fixing member 11 is adapted to be mounted on the first portion 21 of the jewellery item 2, the fixing member 11 having an inner space 110 extending along the axial direction thereof and forming a circle in the axial direction, the side wall of the fixing member 11 being formed with a plurality of positioning holes 111 penetrating to the inner space 110 along the circumference of the axial direction; for example, the positioning holes 111 may be arranged at equal angles within a specific angle range along the circumference of the fixing member 11; as shown in fig. 6, five positioning holes 11 are arranged within one hundred eighty degrees of the circumference of the fixing member 11, that is, adjacent positioning holes 111 are spaced forty-five degrees apart. Of course, the number, the spacing angle and the angle along the circumference of the fixing member 11 of the positioning holes 111 are not limited, and the positioning holes 111 may be actually arranged along the three hundred sixty degrees of the fixing member 11. The fixing member 11 may be manufactured by turning a metal material or by injection molding using a plastic material.

Said rotatable member 12 is adapted to be mounted on the second portion 22 of the item of jewellery 2, the rotatable member 12 being a cylindrical body, an axial end face of the rotatable member 12 being formed with an axially extending extension shaft 121, and preferably an axial end of the extension shaft 121 being formed with an extension bore 122 extending axially a depth. A containing hole 124 extending a certain depth in the radial direction is formed on the side wall of the rotating member 12, and further a spring 15 and a ball 16 are sequentially placed in the containing hole 124, the diameter of the ball 16 is larger than the inner diameter of the positioning hole 111 on the fixing member 11, so that the ball 16 can be properly sunk into the positioning hole 111 but cannot pass through the positioning hole 111; the side wall of the extension shaft 121 is provided with a pin 14 protruding in the radial direction from the outer diameter of the extension shaft 121. The rotary member 12 may be manufactured by turning a metal material or by injection molding using a plastic material.

As shown in fig. 4 and 5, the present invention combines the spring 15 and the ball 16 into the containing hole 124 of the rotating element 12, and then combines the rotating element 12 into the inner space 110 of the fixing element 11 in a movable fit manner, so that the rotating element 12 and the fixing element 11 can rotate relatively, and the ball 16 is confined between one end of the spring 15 and the inner diameter wall of the inner space 110 of the fixing element 11; that is, the spring 15 applies an elastic force to the ball 16 to make the ball 16 have a force moving toward the outer diameter direction of the rotating member 12, so that when the ball 16 is located corresponding to one of the positioning holes 111, the ball 16 can be inserted into the positioning hole 111 for positioning.

In the manner that the pin 14 is provided on the extension shaft 121, a pin hole 123 extending to a certain depth may be provided in a radial direction of a side wall of the extension shaft 121, and one end of the pin 14 may be tightly fitted and fixed in the pin hole 123. Alternatively, the pin 14 may be welded directly to the outer diameter of the extension shaft 121. When the rotary member 12 is manufactured by injection moulding of a plastics material, the pins may be formed directly by injection moulding on the elongate shaft 121.

The limiting member 13 of the present invention is fixedly disposed at an end of the fixing member 11 to limit the angular displacement range of the pin 14 when rotating along with the rotating member 12. That is, when the positioning hole 111 is not disposed along the circumference of the fixing member 11 at three hundred sixty degrees, the limiting member 13 is used to limit the angle that the rotating member 12 can rotate in the clockwise and counterclockwise directions.

as shown in fig. 3 to 5, the limiting member 13 may be a disk-shaped body, the limiting member 13 has a central hole 131 and a fan-shaped hole 132 communicating with the central hole 131, an inner diameter of an arc edge of the fan-shaped hole 132 is larger than an inner diameter of the central hole 131, so as to form a first limiting side 133 and a second limiting side 134 on two opposite sides of the fan-shaped hole 132, respectively.

The limiting member 13 can be fixedly combined with the fixing member 11 by welding, or combined with the fixing member 11 by screwing; when the retaining member 13 is assembled to the fixed member 11, the extending shaft 121 of the rotating member 12 assembled to the fixed member 11 is inserted through the central hole 131, and the pin 14 is located in the fan-shaped hole 132. Therefore, when the rotating member 12 rotates clockwise to a limit angle relative to the fixed member 11, the pin 14 is blocked by the first limit side 133 and cannot rotate any more, and when the rotating member 12 rotates counterclockwise to a limit angle relative to the fixed member 11, the pin 14 is blocked by the second limit side 133 and cannot rotate any more; in other words, the rotating member 12 can only rotate clockwise or counterclockwise within an angular range between the first limit side 133 and the second limit side 134 to adjust the angle of the rotating member 12 with respect to the fixed member 11.

Returning again to FIG. 1, the rotational positioning apparatus 1 of the present invention is mounted to the jewelry article 2 by fixedly mounting the mounting member 11 to the first portion 21 of the jewelry article 2 and fixedly mounting the rotary member 12 to the second portion 22 of the jewelry article 2, wherein a component (not shown) may be disposed within the second portion 22 and extend into the extension bore 122 of the extension shaft 121 to further secure the second portion 22 and the rotary member 12.

Fig. 6 to 8 show the way of adjusting the rotation angle of the rotating member 12 relative to the fixing member 11 by operation of the present invention. If the rotating member 12 and the fixing member 11 are located at the middle position in the state shown in fig. 6, when the rotating member 12 is rotated clockwise by an angle, the balls 16 will be displaced from the middle positioning holes 111 to one of the positioning holes 111 (as shown in fig. 7) clockwise, and cannot rotate any more when the pin 14 is blocked by the first limiting side 133; when the rotating member 12 is rotated counterclockwise by an angle, the ball 16 will be displaced counterclockwise from the middle positioning hole 111 to one of the positioning holes 111 (as shown in fig. 8), and cannot rotate any more when the pin 14 is blocked by the second limit side 134. In other words, when the jewelry item 2 is a doll of jewelry items, the rotation angle of the head of the doll relative to the body part can be adjusted to increase the use interest of the jewelry item. Similarly, when the jewellery system 2 is a jewellery shaped object mounted on an octave case, it can be used to adjust the angle of rotation between the two parts of the object, for example, when the jewellery shaped object is a doll or an animal shaped object, it can be used to rotate the head or limbs of the doll or animal relative to the drive to adjust the angle, thereby adding to the interest of using the octave case.

in addition, jewelry ornaments can also be applied to any object with rotation function, such as ornaments in a doll, an animal doll, a necklace, a pendant, a bracelet, a pin and a music box, … and the like, so as to utilize the rotary positioning device of the utility model as a rotary joint structure between two components.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
