Description
Technical Field
[0001] This utility model relates to the field of jewelry, specifically to a spring chain structure and jewelry. Background Technology
[0002] Chains, as an important component of jewelry, are widely used in necklaces, bracelets, anklets, and other ornaments. Traditional chain structures mostly use single metal links or fixed chain links strung together, resulting in relatively monotonous designs and a lack of flexibility. During wear, if the chain length is unsuitable or the chain is stretched by external forces, it is prone to deformation or even breakage, affecting not only wearing comfort but also reducing the durability of the jewelry.
[0003] The most common types of chain bodies on the market are as follows:
[0004] Ordinary chains: made up of links or woven links strung together. They are characterized by simple structure, but generally lack flexibility and elasticity. They have a plain appearance and do not have adjustable elastic stretching capacity.
[0005] Spring chains: Some chains have springs embedded between the links, but the spring structure is usually exposed, which affects the appearance of the chain and the springs are easily deformed or damaged by external forces, causing the chain to lose its elasticity.
[0006] Decorative chains, such as snake chains, box chains, and fishbone chains, are mainly designed to enhance the appearance and design. However, these chains mostly prioritize visual appeal and lack flexibility and comfort, and do not have elastic stretching properties.
[0007] In summary, existing chain body products have the following shortcomings:
[0008] First, the chain structure is simple and the shape is limited, making it difficult to meet the increasingly diverse jewelry design needs.
[0009] Second, the chain lacks elasticity and cannot be finely adjusted according to wearing needs, making it uncomfortable.
[0010] Third, although some chains incorporate springs, the springs are exposed, affecting the appearance and making them prone to damage and with a short service life;
[0011] Fourth, the combination of chain body and decorative components is limited, and users lack the fun of free combination and matching.
[0012] As consumers increasingly demand personalization, aesthetics, and wearing comfort in jewelry, existing chain designs are no longer sufficient to meet market needs. Therefore, there is an urgent need for a chain structure that combines flexibility with aesthetics and versatility in styling, breaking through the limitations of traditional, monotonous chains and providing the jewelry industry with a new type of chain product. Summary of the Invention
[0013] To address the aforementioned issues, this utility model provides a spring chain structure and jewelry that, while maintaining aesthetic appeal, possesses excellent elasticity and can be paired with various decorative accessories, thereby enhancing the jewelry's appeal and wearing comfort, and meeting the demands of modern consumers for fashionable jewelry.
[0014] This utility model is achieved through the following technical solution: a spring chain body structure, comprising N chain body components and N1 springs.
[0015] The chain body components include circular rings and valve assemblies;
[0016] The circular piece is located at the right end of the chain body component, forming a complete ring structure;
[0017] The valve assembly is located at the left end of the chain body accessory. The valve assembly consists of three gold pieces spaced apart and three arc pieces corresponding to the gold pieces.
[0018] The gold sheets are arranged at intervals along the circumference, with a gap between every two gold sheets, and the three gold sheets form an incomplete circular shape;
[0019] The arc plates are arranged at intervals along the circumference, and a hollow area is provided between every two arc plates;
[0020] The right end of each of the arc plates is connected to the annular plate, and the left end is connected to the outer edge of the corresponding gold plate, so that the corresponding arc plates and the gold plates are enclosed to form a petal body;
[0021] The inner diameter of the circular piece at the right end of the chain body accessory is equal to the diameter of the circular ring formed by the gold piece;
[0022] The spring is a helical spring with a diameter larger than the inner diameter of the annular plate. The spring is disposed in the hollow area between the petal assemblies of the chain body fitting.
[0023] Two adjacent chain body components are inserted into the hollow area of the petal group of the previous chain body component through the gold sheet and cooperate with the spring to realize the sleeve assembly of the chain body components.
[0024] As a preferred technical solution, the circumference of the annular piece is divided into six equal parts, and the arc piece is arranged in a cross-shaped symmetrical arrangement every other part.
[0025] As a preferred technical solution, the arc plate has a centrally raised arc shape along the axial direction of the chain body component.
[0026] As a preferred technical solution, the central angle of each gold sheet is 120°.
[0027] As a preferred technical solution, when the spring is installed, one end of it is attached to the circular piece of the chain body accessory, and the other end contacts the gold piece of the adjacent chain body accessory.
[0028] As a preferred technical solution, the ring plate and the petal assembly of the chain body accessories are integrally molded.
[0029] As a preferred technical solution, the chain body accessories are made of metal or high-strength engineering plastic.
[0030] As a preferred technical solution, the chain body accessories and the spring are assembled alternately in sequence, so that the chain body is in a telescopic state.
[0031] The present invention relates to a type of jewelry, comprising a chain body and a connecting buckle. The connecting buckle is disposed on both sides of the chain body and is used to connect the openings at both ends of the chain body to form a closed ring-shaped wearing cavity.
[0032] The beneficial effects of this utility model are: the spring chain body structure provided by this utility model, by cleverly setting springs inside the chain body accessories, enables the chain body to have elastic extension and contraction function, effectively solving the technical problems of traditional chain body having a single shape, insufficient softness, and lack of elasticity.
[0033] On the one hand, the chain structure can quickly return to its original shape after being stretched, thanks to the spring's rebound force, ensuring the chain always maintains a full and rounded appearance and is less prone to loosening or deformation, further enhancing the overall aesthetics of the jewelry. On the other hand, the chain has good flexibility and resilience, adapting to different wrist or neck sizes when worn, and its comfort is not affected even when stretched during activity, thus improving the wearing experience. At the same time, the chain structure conceals the complex spring mechanism within the geometric chain components, resulting in a simpler and more stylish appearance, meeting the modern consumer's demand for jewelry that combines aesthetics and functionality.
[0034] In addition, the chain structure can be combined with spring buckles and various decorative accessories to achieve free splicing of various jewelry forms such as bracelets and necklaces, providing users with the fun of personalized matching. It breaks through the limitations of the single and fixed traditional chain structure, further broadens the usage scenarios of jewelry, enhances the added value of products, and conforms to the development trend of the jewelry market pursuing fashion and diversification.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0049] like Figures 1-8As shown, this utility model discloses a spring chain body structure comprising N chain body components 1 and N1 springs 2 connected together to form a spring chain body 100, where N is a positive integer greater than or equal to 2. The chain body component 1 is the main component of this structure. Each chain body component 1 includes a circular ring plate 12 at the right end and a petal assembly at the left end. The circular ring plate 12 has a complete ring structure, its shape being an axially penetrating circular ring. This circular ring plate 12 serves as the connecting part at the right end of the chain body component 1, used to fit the petal assembly of the adjacent chain body component 1. The petal assembly is located at the left end of the chain body component 1. This petal assembly consists of three gold plates 13 arranged circumferentially and three arc plates 11 corresponding to the three gold plates 13. The beginning and end ends of the spring chain body are connected by a head 200.
[0050] Gold pieces 13 are distributed along the circumference of the left end of the chain body component 1, with a gap between each pair of adjacent gold pieces 13. The three gold pieces 13 together form an incomplete circular structure. Arc pieces 11 are distributed along the circumference of the left end of the chain body component 1, with a hollow area 3 between each pair of adjacent arc pieces 11. The right end of each arc piece 11 is connected to the circular piece 12 of the chain body component 1, and the left end is connected to the outer edge of the corresponding gold piece 13, so that the gold piece 13 and the arc piece 11 enclose a petal. Through the above structure, the inner diameter of the circular piece 12 at the right end of the chain body component 1 is equal to the diameter of the incomplete circular ring formed by the gold pieces 13 at the left end, so that adjacent chain body components 1 can be nested together.
[0051] Spring 2 is a helical spring, with an outer diameter slightly larger than the inner diameter of the right-end ring plate 12 of the chain body accessory 1, allowing it to fit into the hollow area 3 formed by the petal assembly of the chain body accessory 1. During assembly, the left-end petal assembly of the chain body accessory 1 is inserted into the inner cavity of the right-end ring plate 12 of the adjacent chain body accessory 1, so that the gold plate 13 of the subsequent chain body accessory 1 passes through the hollow area 3 of the petal assembly of the preceding chain body accessory 1, and spring 2 is sleeved inside the gold plate 13. During assembly, spring 2 is positioned between the gold plate 13 of the subsequent chain body accessory 1 and the ring plate 12 of the preceding chain body accessory 1, thus covering the gold plate 13 of the subsequent chain body accessory 1.
[0052] When installing the chain body, first, place the spring 21 into the hollow area 3 of the petal assembly of the chain body accessory 11, and bring the spring 21 close to the circular piece 12 at the right end of the chain body accessory 11. Then, insert the gold piece 13 of the chain body accessory 12 into the hollow area 3 of the petal assembly of the chain body accessory 11, and let the spring 21 fit onto the gold piece 13 of the chain body accessory 12, thereby connecting and fixing the chain body accessory 11 and the chain body accessory 12. Subsequently, place the spring 22 into the hollow area 3 of the petal assembly of the chain body accessory 12, and bring the spring 22 close to the circular piece 12 at the right end of the chain body accessory 12. Then, insert the gold piece 13 of the chain body accessory 13 into the hollow area 3 of the petal assembly of the chain body accessory 12, and let the spring 22 fit onto the gold piece 13 of the chain body accessory 13, thereby connecting the chain body accessory 12 and the chain body accessory 13. Similarly, the remaining chain body parts 1 and spring 2 are assembled one by one in the above manner to complete the installation of the entire spring 2 chain body.
[0053] When the chain body is not under stress, the chain components 1 are closely fitted together, and the spring 2 is in a natural state, unaffected by external forces. When the chain body is stretched, the circular plates 12 and gold plates 13 of adjacent chain components 1 move relative to each other, and the spring 2 is compressed and deformed, thus storing elastic potential energy. When the external force disappears, the spring 2 releases its potential energy and returns to its original shape, pushing the chain components 1 back to their original positions, causing the chain body to spring back to its full state.
[0054] In its implementation, the chain structure of this spring 2 also features the following optimized designs: The circumference of the right-end circular ring 12 of the chain component 1 is divided into six equal parts, with an arc plate 11 placed at every other part, so that the three arc plates 11 are evenly distributed in a cross-symmetrical pattern, improving the uniformity of force distribution and overall stability of the chain component 1. The arc plates 11 have a centrally raised arc shape along the axial direction of the chain component 1 to enhance the structural strength of the arc plates 11, while also improving the three-dimensionality and smoothness of the chain's appearance. The central angle of each gold plate 13 is approximately 120°, which can form a stable three-lobed structure, facilitating the nesting assembly between chain components 1 and ensuring the overall strength of the chain.
[0055] In terms of material selection, the chain body component 1 can be made of metal materials, such as stainless steel or precious metals, to ensure the strength and durability of the chain body; alternatively, high-strength engineering plastics can be used to reduce the weight of the chain body and meet the needs of different consumer groups. The spring 2 is made of steel wire, which has good elasticity and fatigue resistance, and can maintain the elastic function of the chain body for a long time.
[0056] The chain body accessory 1 and spring 2 of this spring 2 chain are assembled in an alternating manner, making the chain body as a whole in a stretchable state. When the chain body is stretched by external force, the chain body can adapt to different size requirements; when the external force is removed, the chain body can quickly return to its original shape, always maintaining a full appearance and avoiding the chain body from becoming loose or deformed.
[0057] This utility model also includes a piece of jewelry comprising the aforementioned spring 2 chain structure and connecting buckles. The connecting buckles are located at both ends of the chain body and are used to connect the open ends of the chain body to form a closed, ring-shaped wearing cavity, allowing the chain body to be worn as a bracelet, necklace, or anklet on the body. The connecting buckles at both ends of the chain body can match the appearance and style of the chain body, enhancing the overall aesthetics. Furthermore, different styles of decorative parts can be replaced according to user needs, achieving personalized matching of the jewelry and further increasing the product's fun and fashion sense.
[0058] The above embodiments are merely specific implementations of this utility model and do not constitute a limitation on the scope of protection of this utility model. Without departing from the design concept of this utility model, those skilled in the art can make several modifications and improvements, and these modifications and improvements should all be considered within the scope of protection of this utility model.
[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
