一种薄型旋转戒指
By incorporating a ball bearing mechanism between the inner and outer rings of the rotating ring, the problems of high rotational resistance, short lifespan, large thickness, and difficult assembly of existing rotating rings are solved, resulting in a thinner, smoother, more durable, and aesthetically pleasing rotating ring design.

AI Technical Summary
Existing rotating rings suffer from problems such as high rotational resistance, short lifespan, easy loosening, excessive product thickness, difficult assembly, and poor aesthetics. In particular, the traditional bearing structure results in large gaps and side covers that affect wearing comfort.
The ball bearing mechanism between the inner and outer rings includes balls, ball channels, cages, and ball loading channels. Seamless connection is achieved through the ball channels and guide grooves of the inner and outer rings. Combined with the cage and micro-flange structure, the assembly process is simplified, ensuring smooth rotation and durability.
It achieves a ring thickness of less than 2.5mm, making it comfortable to wear, smooth to rotate, highly durable, easy to assemble, suitable for mass production and aesthetics, and highly expandable, avoiding the gaps and jamming problems of traditional bearing structures.

Abstract
Claims
1. A thin rotating ring comprising an inner ring and an outer ring fitted outside the inner ring, characterized in that: A ball bearing mechanism is provided between the inner and outer rings. The ball bearing mechanism includes balls, a ball channel, a cage, and a ball loading channel. A ball channel is formed between the inner and outer rings. A cage is provided on one side of the ball channel. The ball holding hole of the cage extends into the ball channel. The ball loading channel includes a ball loading port and a ball guide groove. The ball guide groove communicates with the ball channel. The ball loading port is opened on the inner ring or the outer ring and communicates with the ball guide groove.
2. A thin rotating ring as claimed in claim 1, characterized in that: The ball-rolling channel includes an inner ball-rolling channel and an outer ball-rolling channel. The inner ball-rolling channel is formed by a recess on the outer side of the inner ring, and the outer ball-rolling channel is formed by a recess on the inner side of the outer ring. The inner and outer ball-rolling channels have corresponding inner and outer arc shapes.
3. A thin rotating ring as claimed in claim 1, characterized in that: The ball loading port is located on the inner ring, and the ball guide groove includes an inner guide groove and an outer guide groove. The inner guide groove is located on the outside of the inner ring and communicates with the ball loading port. The outer guide groove is located on the outside of the outer ring and corresponds to the position of the inner guide groove. The inner guide groove and the outer guide groove together form a ball guide groove that is slightly larger than the diameter of the ball.
4. A thin rotating ring as claimed in claim 1, characterized in that: The ball loading port is located on the outer ring, and the ball guide groove includes an inner guide groove and an outer guide groove. The outer guide groove is located on the inner side of the outer ring and communicates with the ball loading port. The inner guide groove is located on the outer side of the inner ring and corresponds to the position of the outer guide groove. The inner guide groove and the outer guide groove together form a ball guide groove that is slightly larger than the diameter of the ball.
5. A thin rotating ring as claimed in claim 1, characterized in that: The bottom of the ball guide groove is higher than the ball channel so that the ball can transition to the ball channel in a curved manner.
6. A thin rotating ring as claimed in claim 1, characterized in that: The ball channel has a frame groove on one side, the retainer is fitted into the frame groove, the ball guide groove passes through the frame groove, the retainer includes a frame body and ball catch holes, wherein the ball catch holes are evenly arrayed on the frame body and can be used as indexing marks during assembly.
7. A thin rotating ring as claimed in claim 6, characterized in that: The ball-holding hole has an open thin lip or chamfer design on the side near the window to facilitate ball insertion.
8. A thin rotating ring as claimed in claim 4, characterized in that: The ball loading port is closed by a conical plug of the same material, which is fixed by pulsed laser spot welding and sealed by grinding and polishing.
9. A thin rotating ring as claimed in claim 1, characterized in that: The ball bearing mechanism has several sets arranged between the inner and outer rings.
10. A thin rotating ring as claimed in claim 1, characterized in that: The outer and / or inner edges of the cage are provided with micro-flanges, which respectively mate with shallow guide grooves on the outer and / or inner rings to maintain the axial positioning of the cage.
