[0003] The present utility model relates to the aforementioned deficiencies of the prior art and offers a rotatable structure for gold jewelry with precise positioning.

[0004] The technical solution of the utility model for overcoming the technical problem consists of constructing a rotatable structure for gold jewelry with precise positioning, comprising a fixed part, a decorative part rotatably attached to the fixed part, a pivot pin for rotatably connecting the fixed part and the decorative part, and an elastic element placed over the pivot pin, wherein an underside of the decorative part is provided with a first positioning pin and a second positioning pin that project beyond the decorative part, and an underside of the fixed part is provided with an arc-shaped groove into which the first positioning pin and the second positioning pin can be inserted and moved, wherein both ends of the arc-shaped groove are provided with a first positioning groove and a second positioning groove into which the first positioning pin and the second positioning pin can be inserted and positioned.and the elastic element serves to elastically push the decorative part against it and to insert the first positioning pin and the second positioning pin into the first and second positioning grooves.

[0005] In the rotatable structure of the present utility model, an upper part of the pivot pin is provided with a pin cap whose diameter is larger than the diameter of the pivot pin.

[0006] In the rotatable structure of the present utility model, a first wave hole is provided in the decorative part, through which the pivot pin can be rotatably guided, and an upper part of the fixed part has a second wave hole, through which the pivot pin can be rotatably guided, wherein an adapter cavity is arranged on the fixed part below the second wave hole, the diameter of which is larger than the diameter of the second wave hole.

[0007] In the rotatable structure of the present utility model, a bearing housing is arranged in the adapter cavity, which is rotatable in the adapter cavity, wherein a thickness of the bearing housing corresponds to a height of the adapter cavity and the bearing housing is rotatable in the adapter cavity.

[0008] In the rotatable structure of the present utility model, a lower end of the pivot pin is firmly connected to the bearing housing, the elastic element is placed on the pivot pin and is located between the pin cap and the decorative part.

[0009] In the rotatable structure of the present utility model, the elastic element is a spring, the upper end of which rests elastically against the pen cap and the lower end of which rests elastically against the decorative part.

[0010] In the rotatable structure of the present utility model, the arc groove is a circular arc-shaped slot, the first positioning pin and the second positioning pin are each arranged on two sides of the decorative part, and the first positioning groove and the second positioning groove are each arranged on the corresponding two sides of the arc groove.

[0011] The design of the rotatable structure for gold jewelry with precise positioning, as described in this utility model, offers the following advantages: When the rotatable structure is used, the first and second positioning pins slide along the curved slot as the decorative element is rotated, while the elastic element is compressed. Once the positioning pins reach the first and second positioning recesses, the elastic element, due to its own elastic restoring force, presses the pins into the recesses, producing a distinct "click" sound and providing clear tactile feedback, thus achieving precise and stable positioning. If further rotation is required, sufficient drive torque must be applied to release the positioning pins from the positioning recesses and overcome the elastic force. Description of the characters
