Description

Technical Field

[0001] This utility model relates to the field of jewelry products, and more specifically to a spiral combination jewelry. Background Technology

[0002] Rings have become an indispensable accessory in people's lives. Current ring designs are mostly based on a fixed single-ring structure, resulting in a limited form and no flexibility in changing how they are worn, thus restricting their decorative effect. While some two-piece rings use a detachable structure, they usually rely on external clasps or connectors, leading to cumbersome assembly and disassembly, and a loose structure after assembly. Furthermore, traditional spiral rings often use a one-piece decorative design, which cannot be disassembled into two separate rings, lacking visual interest. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a spiral combination jewelry, which aims to solve the technical problems of the cumbersome assembly and disassembly or lack of fun of the existing combination jewelry.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spiral-shaped jewelry piece includes a first ring and a second ring with the same structure as the first ring. The first ring is rotatably connected to the second ring, allowing the first ring and the second ring to switch between an engaged state and a disengaged state. In the engaged state, the first ring and the second ring are snapped together to form a cylindrical jewelry body. In the disengaged state, the first ring and the second ring are separated from each other.

[0006] The first ring includes a base and a connecting ring. The connecting ring extends upward from the base and is a long strip structure wound in a spiral shape. There is a connection interval equal to the height of the connecting ring between two adjacent layers of connecting rings in the radial direction of the spiral structure. A wearing cavity is formed inside the base and the connecting ring.

[0007] In one embodiment, the inner diameter of the connecting ring is equal to the inner diameter of the base, and the wearing cavity is cylindrical.

[0008] In one embodiment, the base is a columnar body, and the side of the base near the connecting ring is an extension surface, which is a horizontal surface.

[0009] In one embodiment, the connecting ring includes a fixed section, an extension section, and a connecting section. The fixed section is connected to the extension surface. The extension section and the connecting section extend outward from the fixed section in a spiral manner. The side of the connecting section away from the base is the connecting surface, which is parallel to the extension surface.

[0010] In one embodiment, a first connecting groove with the same height as the connecting section is provided between the base and the extension section, and a second connecting groove with the same height as the extension section is provided between two adjacent layers of the extension section. The first connecting groove communicates with the second connecting groove to form the connecting interval.

[0011] In one embodiment, the height of the connecting segment decreases sequentially from the end where the connecting segment is connected to the extension segment towards the other end of the connecting segment; the height of the fixing segment decreases sequentially from the end where the fixing segment is connected to the extension segment towards the other end of the fixing segment.

[0012] In one embodiment, in the engaged state, the connecting ring of the first ring is fitted into the connecting gap of the second ring, the connecting ring of the second ring is fitted into the connecting gap of the second ring, and the inner peripheral wall of the first ring and the inner peripheral wall of the second ring smoothly transition to form the inner surface of the jewelry body.

[0013] In one embodiment, the cross-sectional shape of the connecting ring along the spiral extension direction is rectangular.

[0014] In one embodiment, the width of the connecting ring is equal from top to bottom.

[0015] In one embodiment, the jewelry further includes a chain that passes through the wearing cavity to attach the jewelry body to the chain.

[0016] The advantages of this invention compared to existing technologies are as follows: The two symmetrical first and second rings can be rotated to switch between engaged and disengaged states. When engaged, the spiral connecting rings nest together to form a complete cylindrical jewelry body, resulting in a stable structure and visual unity. When disengaged, they become two independent rings. The radial interlayer spacing of the spiral connecting rings is equal to their height, ensuring smooth engagement during rotation and enhancing the three-dimensional decorative effect through the spiral texture. Through the combination of mechanical structure and aesthetic form, the jewelry body combines playful playfulness with decorative practicality in its transformation.

[0017] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of this utility model more obvious and easy to understand, the following are preferred embodiments, which are described in detail below.

[0030] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0031] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0032] See Figures 1 to 7 As shown, this utility model embodiment discloses a spiral combination jewelry, including a first ring 2 and a second ring 5 with the same structure as the first ring 2. The first ring 2 is rotatably connected to the second ring 5 so that the first ring 2 and the second ring 5 can switch between an engaged state and a disengaged state. In the engaged state, the first ring 2 and the second ring 5 are engaged with each other to form a cylindrical jewelry body 1. In the disengaged state, the first ring 2 and the second ring 5 are separated from each other.

[0033] The first ring 2 includes a base 3 and a connecting ring 4. The connecting ring 4 extends upward from the base 3 and is a long strip structure wound in a spiral shape. There is a connection interval 44 between two adjacent connecting rings 4 in the radial direction of the spiral structure, which is equal to the height of the connecting ring 4. A wearing cavity 11 is formed inside the base 3 and the connecting ring 4.

[0034] Specifically, this embodiment protects a spiral combination jewelry piece, which achieves switching between engaged and disengaged states through the rotational connection of two completely symmetrical first rings 2 and second rings 5. Based on the complementary nesting of symmetrical spiral structures: in the engaged state, the spiral connecting rings 4 of the two rings interlock to form a complete columnar jewelry body 1, while in the disengaged state, they are separated into two independent rings. Furthermore, the connecting rings 4 are formed by spirally extending upwards from the base 3, and the connection interval 44 between adjacent spiral layers is equal to the height of the connecting rings 4, ensuring precise alignment when the two rings rotate. The self-locking characteristic of the spiral structure ensures structural stability after engagement. Simultaneously, the wearing cavity 11 penetrates the interior of the base 3 and the connecting rings 4, improving wearing comfort. It is understood that in this embodiment, the spiral angle or number of layers is not limited; only the correspondence between the interval and height needs to be maintained to ensure the rotational locking function. In specific implementations, appropriate adjustments can be made according to actual needs. Furthermore, in this embodiment, the outer diameter of the base 3 is larger than the outer diameter of the connecting rings 4. It is understood that in other embodiments, the outer diameter of the base 3 and the outer diameter of the connecting ring 4 can also be designed to be equal, so as to retain the complete single ring shape in the separated state, forming the first ring 2 of the base 3 and the serpentine connecting ring 4, which satisfies diverse wearing needs while ensuring aesthetics.

[0035] In one embodiment, the inner diameter of the connecting ring 4 is equal to the inner diameter of the base 3, and the wearing cavity 11 is cylindrical.

[0036] Specifically, the inner diameter of the connecting ring 4 is equal to the inner diameter of the base 3, and the wearing cavity 11 is cylindrical. This consistency in inner and outer diameters ensures a smooth transition of the inner surface when the jewelry body 1 is joined, preventing sharp edges from rubbing against the fingers. Furthermore, the inner diameter of the base 3 is aligned with the inner diameter of the starting end of the spiral structure, creating a continuous cylindrical space within the double rings after nesting, adapting to standard finger sizes and reducing customized production costs.

[0037] In one embodiment, the base 3 is a columnar body, and the side of the base 3 near the connecting ring 4 is an extension surface 31, which is a horizontal surface.

[0038] Specifically, the base 3 is a columnar body, with a horizontally extending surface 31 on the side near the connecting ring 4. The horizontally extending surface 31 provides a stable initial support plane for the spiral connecting ring 4, ensuring the uniform unfolding of the spiral structure. In other words, the extending surface 31 contacts the corresponding plane of the symmetrical ring, limiting the rotational axial displacement. This improves the accuracy of the double ring rotational alignment while enhancing the overall mechanical strength through the columnar structure of the base 3. It is understood that the base 3 adopts a columnar shape in this embodiment, but in other embodiments, it may also adopt different shapes such as a ring; no specific limitation is made.

[0039] In one embodiment, the connecting ring 4 includes a fixed section 41, an extension section 42, and a connecting section 43. The fixed section 41 is connected to the extension surface 31. The extension section 42 and the connecting section 43 extend outward from the fixed section 41 in a spiral manner. The side of the connecting section 43 away from the base 3 is the connecting surface 431, which is parallel to the extension surface 31.

[0040] Specifically, the connecting ring 4 is subdivided into a fixed segment 41, an extension segment 42, and a connecting segment 43. The fixed segment 41 is connected to the extension surface 31 of the base 3. The extension segment 42 and the connecting segment 43 extend outward in a spiral, and the connecting surface 431 is parallel to the extension surface 31. The spiral extension trajectory is controlled by the segmented structure: the fixed segment 41 is connected to the base 3 to provide a rigid anchor point; the extension segment 42 realizes the spiral helix angle and precisely controls the spacing between spiral layers; the connecting segment 43 ensures that it fits the plane of the symmetrical second ring 5 through the parallel connecting surface 431, and the parallel design of the connecting surface 431 reduces rotational friction resistance.

[0041] In one embodiment, a first connecting groove 441 with the same height as the connecting section 43 is provided between the base 3 and the extension section 42, and a second connecting groove 442 with the same height as the extension section 42 is provided between two adjacent layers of the extension section 42. The first connecting groove 441 communicates with the second connecting groove 442 to form the connecting interval 44.

[0042] Specifically, a first connecting groove 441 is provided between the base 3 and the extension 42, and a second connecting groove 442 is provided between adjacent extensions 42. The heights of the first connecting groove 441 and the second connecting groove 442 are equal to the heights of the connecting section 43 and the extension 42, respectively. The groove structure provides space for the symmetrical rings to be inserted, allowing the connecting section 43 and the extension 42 to sequentially enter their respective grooves when the double rings rotate. During operation, the first connecting groove 441 guides the initial fitting, while the second connecting groove 442 maintains subsequent interlayer alignment, thereby achieving multi-level progressive fitting and improving the stability of the joint. Simultaneously, the height-matched first connecting groove 441 and second connecting groove 442 prevent structural interference.

[0043] In one embodiment, the height of the connecting segment 43 decreases sequentially from the end where the connecting segment 43 is connected to the extension segment 42 toward the other end of the connecting segment 43; the height of the fixing segment 41 decreases sequentially from the end where the fixing segment 41 is connected to the extension segment 42 toward the other end of the fixing segment 41.

[0044] Specifically, the heights of the connecting section 43 and the fixed section 41 gradually decrease, optimizing the force distribution during the fitting process through the height gradient change: the height of the connecting section 43 decreases from the inside to the outside, making it easier for the tip of the connecting section 43 of the symmetrical second ring 5 to slide into the first connecting groove 441 of the symmetrical ring, reducing the torque required for rotation operation; the decreasing height of the fixed section 41 reduces the stress concentration at the connection between the base 3 and the extension section 42, avoiding metal wear caused by hard collision.

[0045] In one embodiment, in the engaged state, the connecting ring 4 of the first ring 2 is fitted into the connecting gap 44 of the second ring 5, and the connecting ring 4 of the second ring 5 is fitted into the connecting gap 44 of the second ring 5. The inner peripheral wall of the first ring 2 and the inner peripheral wall of the second ring 5 smoothly transition to form the inner surface of the jewelry body 1.

[0046] Specifically, in the engaged state, the connecting rings 4 of the first ring 2 and the second ring 5 are interlocked within each other's connecting gaps 44, with smooth transitions in their inner circumferences. Through precise matching of the spiral interlayer spacing, the connecting rings 4 of the first ring 2 and the second ring 5 completely fill each other's reserved spaces, while the inner walls remain continuously smooth, eliminating gaps at the joint surfaces, enhancing visual integrity and improving wearing comfort. During operation, the connecting rings 4 of the first ring 2 are embedded in the connecting gaps 44 of the second ring 5, and vice versa, forming an interlocking nesting structure.

[0047] In one embodiment, the cross-sectional shape of the connecting ring 4 along the spiral extension direction is rectangular.

[0048] Specifically, in this embodiment, the connecting ring 4 has a rectangular cross-sectional shape along the spiral extension direction. The rectangular cross-section provides the maximum contact area, enhancing the torsional resistance of the mating surface. The top and bottom surfaces of the connecting ring 4 contact the inner wall of the connecting gap 44 of the symmetrical ring, forming surface-to-surface friction, thereby improving the structural rigidity in the joined state; at the same time, the rectangular edges are easy to process and shape. It can be understood that, in order to increase the interest of the jewelry body 1, a rounded corner design can also be added to the outer edge of the connecting ring 4, and the radius of the rounded corner should be smaller than the width of the top and bottom surfaces.

[0049] Furthermore, in other embodiments, the connecting ring 4 can also be a cylindrical ring with a circular vertical cross-section. In specific implementations, when the two rings are rotated together, the outer wall of the circular cross-section connecting ring 4 forms line contact with the inner wall of the connecting gap 44 of the symmetrical rings, reducing frictional resistance. At the same time, the rounded corner structure automatically guides alignment during fitting. Based on the symmetry and lack of sharp edges of the circular contour, the smoothness of rotation is improved by reducing the local stress on the contact surface.

[0050] In one embodiment, the width of the connecting ring 4 is equal from top to bottom.

[0051] Specifically, the connecting ring 4 has a uniform width from top to bottom. This equal-width structure simplifies the manufacturing process while ensuring consistent spacing between the spiral layers. During operation, the uniform-width connecting ring 4 ensures even stress distribution across all layers during rotational engagement, preventing localized stress concentration caused by width variations. In other embodiments, it can also be designed with a tapered width, but the inner diameter of the connecting ring 4 must remain consistent in the radial direction to enhance both comfort and enjoyment.

[0052] In one embodiment, the first ring 2 and the second ring 5 are made of different non-ferrous metals or are processed using different surface treatment processes.

[0053] Specifically, in this embodiment, the first ring 2 and the second ring 5 can be made of different materials or have different surface treatments. The visual contrast of the two rings is enhanced by differences in materials (such as gold and platinum) or processes (such as polishing and brushing), creating an artistic aesthetic of material / texture interaction when joined. In other embodiments, surface differentiation can be achieved through processes such as electroplating and sandblasting. It is understood that the process differences between the first ring 2 and the second ring 5 in this embodiment are only to improve aesthetics and interest; however, in other embodiments, the first ring 2 and the second ring 5 can also be designed with the same material and process to reduce manufacturing costs. Furthermore, to increase aesthetics, decorative elements such as added patterns or diamond inlay can be added to the surface of the rings; this is not specifically limited in this embodiment.

[0054] Furthermore, the connecting ring 4 and the base 3 are fixedly connected by welding or by integral molding.

[0055] Specifically, in this embodiment, the connecting ring 4 and the base 3 are welded together. Reliable fixing of the connecting ring 4 and the base 3 is achieved through localized melting, while retaining flexibility in material selection. Thus, in practical implementation, the base 3 and the connecting ring 4 are processed as independent components (e.g., the base 3 is cast, and the connecting ring 4 is formed by wire cutting). Then, welding points are pre-set on the extension surface 31 of the base 3, and micro-beam laser welding is used to precisely weld the root of the connecting ring 4 to the base 3, ensuring that the spiral extension direction is perpendicular to the axis of the base 3. In this embodiment, dissimilar materials are allowed for the base 3 and the connecting ring 4 (e.g., the base 3 is a high-hardness titanium alloy, and the connecting ring 4 is a ductile silver material), balancing structural strength and processing feasibility; simultaneously, the welding points are hidden inside the base 3, avoiding exposed weld marks that affect the appearance.

[0056] In another embodiment, a one-piece molding process is adopted to eliminate the connection interface through integral manufacturing, ensuring the structural continuity between the base 3 and the connecting ring 4. During implementation, the base 3 and the spiral connecting ring 4 are formed in one piece, directly constructing a gradual transition structure between the spiral connecting ring 4 and the base 3, thereby eliminating stress concentration points that may be generated during welding or assembly, and improving the overall torsional strength of the jewelry body 1; at the same time, it reduces processing steps and reduces the error in the fit of multiple parts.

[0057] It is understandable that in actual production, the appropriate molding process can be selected according to actual needs, and no specific restrictions are imposed in this embodiment.

[0058] In one embodiment, the jewelry further includes a chain (not shown) that passes through the wearing cavity 11 to attach the jewelry body 1 to the chain.

[0059] Specifically, in this embodiment, while retaining the core function of the jewelry body 1 as a ring, a chain that can be threaded into the wearing cavity 11 is added to flexibly expand the jewelry's function. When the chain is threaded through the wearing cavity 11 and closed into a loop, the cylindrical jewelry body 1 in its engaged state naturally hangs and rotates with the wearer's movements, and can be directly used as a pendant. When the jewelry body 1 is in a separated state, the two independent rings can each be threaded with a thin chain, transforming into a stacked bracelet or a symmetrical pendant combination, meeting the needs of multiple wearing scenarios. In other words, in this embodiment, by adding a simple chain, the jewelry body 1 can be integrated into three wearing forms: ring, necklace, and bracelet, improving usability and cost-effectiveness. The wearing cavity 11 remains adaptable to finger size even when the chain is threaded, without affecting the function of the jewelry body 1 as a ring.

[0060] In summary, this embodiment of a spiral combination jewelry piece achieves a unity of form transformation, structural stability, and decorative aesthetics through a symmetrical spiral structure design with two rings. The first ring 2 and the second ring 5, through the rotating nesting of the spiral connecting ring 4, can form a complete cylindrical ring in the joined state. The strict matching of the layer spacing and the height of the connecting ring 4 ensures a tight fit and smooth rotation. After separation, each ring retains its complete spiral shape, supporting individual or combined wear, enhancing flexibility. The self-locking characteristic of the spiral structure and the columnar support design of the base 3 enhance the torsional resistance after joining, while the through-type cylindrical wearing cavity 11 adapts to different finger sizes and ensures comfort. Furthermore, the differentiated material / process selection of the two rings further optimizes the fitting precision, tactile feel, and visual hierarchy, giving the product both the practicality of a mechanical structure and the decorative beauty of spiral aesthetics.
