Technical Field

[0001] The utility model relates to the technical field of jewellery, in particular to a ring-shaped ornament. Background Art

[0002] Ring-shaped jewelry, mostly referring to the bands of bracelets and rings, is generally a closed circular structure. Bracelets, for example, are difficult to wear with wide hands, and generally require a larger size. This can make them loose on the wrist, hindering wrist movement and easily causing bumps on the bracelet. Rings, on the other hand, can appear too tight or too loose after being worn due to weight gain or weight loss.

[0003] In response to the above-mentioned problems, authorization announcement No. CN218635464U discloses a ring-shaped ornament, which realizes that the inner ring has an adjustment function to solve the above-mentioned problems.

[0028] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] Example: Refer to Figure 1-6 As shown, the utility model provides a ring-shaped ornament, including an outer ring body 1 and an inner ring body 2, wherein outer edges 11 are radially provided on both sides of the outer ring body 1, and the inner ring body 2 is movably installed in a U-shaped groove formed by the outer ring body 1 and the outer edge 11, and the outer edge 11 on one side of the outer ring body 1 is welded to the outer ring body 1, and then the inner ring body 2 is placed and the outer edge 11 on the other side is welded.

[0032] The inner ring body 2 is composed of three arc-shaped bodies 21. The arc-shaped bodies 21 are each provided with an arc-shaped spring piece 3. The arc-shaped spring piece 3 is installed on the outside of the arc-shaped body 21. The arc-shaped body 21 is provided with two bases 213 opposite to each other. The base 213 is provided with a clamping column 214 with a C-shaped notch. Specifically, the two bases 213 are arranged at intervals in the middle part of the side of the arc-shaped body 21 opposite to the inner side of the outer ring body 1. The clamping column 214 is vertically arranged on the outside of the base 213, and the opposite side of the clamping column 214 is provided with a C-shaped notch.

[0033] Cross bars 31 are provided on both sides of the middle of the arc-shaped spring piece 3 , and the cross bars 31 are matched with the C-shaped notches of the clamping column 214 to achieve the installation of the arc-shaped spring piece 3 .

[0034] The base 213 is provided to elevate the position of the arc-shaped spring piece 3 so that the curvature of the arc-shaped spring piece 3 can be smaller.

[0035] It is therefore suitable to use precious metals to make the curved spring piece 3, such as gold or silver, because they are relatively soft. If they are made into the curved spring piece 3, if the curvature is too large, the effect of the spring piece will be easily lost.

[0036] Both ends of the arc body 21 are arc heads 211, and a protrusion 212 is extended outward on one side of the arc head 211; the protrusions 212 on adjacent arc bodies 21 are in opposite directions, that is, the protrusions 212 at both ends of the same arc body 21 are located on both sides respectively.

[0037] The protrusions 212 on the adjacent arc-shaped bodies 21 are cross-connected, and limiting posts 4 are provided between the cross-connected protrusions 212 .

[0038] Preferably, an H-shaped limiting piece 12 is provided on the outer edge 11 , and two sides of the H-shaped limiting piece are fixedly welded to the outer edge 11 .

[0039] Preferably, the limiting column 4 is provided on the H-shaped limiting piece 12 .

[0040] During wearing, the arc-shaped body 21 is pressed, and the protrusions 212 on the adjacent arc-shaped bodies 21 slide along the two sides of the limiting column 4 respectively.

[0041] Preferably, the U-shaped portion of the H-shaped limiting piece 12 is in an arc shape 121 , and the arc shape 121 fits in place with the arc head 211 .

[0042] To sum up, the beneficial effects of the utility model include providing a ring-shaped ornament with a simple structure. When the arc-shaped body of the inner ring body contracts or protrudes outward, the protrusion slides up and down along the limiting column, thereby solving the problem that the arc-shaped body is easily stuck; at the same time, the limiting column and the outer edge jointly limit the travel range of the arc-shaped body, so there is no need to set vertical edges on both sides of the arc-shaped body, thereby reducing material usage and reducing production processes. The setting of the limiting column also solves the problem that the protrusion is easily misplaced during contraction or protrusion.
