Description

Technical Field

[0001] This utility model relates to the field of jewelry adjustment structure technology, and in particular to a piece of jewelry with an extendable opening. Background Technology

[0002] Adjustable-size jewelry is a category of jewelry primarily in the form of rings, bracelets, and anklets. Its core characteristic is that the size of the ring can be flexibly adjusted to suit the wearer's needs. This type of jewelry typically uses metals (such as silver, gold, and alloys) as a base material, and some pieces are decorated with gemstones, enamel, pearls, etc., balancing aesthetics and practicality. It is widely used for everyday wear, gift-giving, wedding anniversaries, and other occasions.

[0003] Because traditional metal jewelry often uses integrated forging or casting processes, the size of the ring is fixed. When the wearer needs to adjust the ring to fit their own dimensions, it can often only be achieved through a forced "physical deformation" method. This is difficult to operate, and the wearer cannot accurately control the degree of deformation. It is easy for the ring to be adjusted too large, causing the jewelry to loosen and fall off, or adjusted too small, causing the jewelry to get stuck or press against the skin.

[0004] Therefore, this application proposes a jewelry with an adjustable opening to solve the above problems. Utility Model Content

The rotating plate 14 drives the rotating rod 10 and the lower adjusting gear 8 to rotate through the cooperation of the limiting post 15, the synchronous frame 17 and the synchronous through hole 11. Under the cooperation of the adjusting gear 8 and the mating tooth groove 6, the adjusting section 1 2 and the adjusting section 2 3 are moved in a misaligned manner, thereby adjusting the distance between the two ends of the arc-shaped decorative section 1, and thus realizing the adjustment of the ring size of the jewelry. The device adjusts the surgical ring size by engaging the adjusting gear 8 with the mating groove 6. This upgrades the traditional method of adjusting jewelry by directly bending and pulling to a precise, mechanized adjustment. The entire process requires no external tools, and the adjustment force is gentle and the stroke is controllable, avoiding the problems of the ring size being too large or too small in traditional adjustment methods. The engagement of the locking groove 13 and the locking rod 18 ensures that the jewelry remains stable at the adjusted ring size after adjustment. Furthermore, the adjusting gear 8 is located inside the adjusting frame 7, and the mating groove 6 is located within the mating groove 5, thus preventing the adjustment function from damaging the appearance of the jewelry.
