[0032] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0033] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0034] like Figures 1-6 As shown, this utility model provides a spring chain clasp, comprising a first clasp head accessory 1, a second clasp head accessory 2, a circular sealing sleeve 13, three springs 4, and three gold studs 15, etc., forming a spring chain clasp 200. The components are fitted together to achieve the safety and convenience of the clasp function, as well as a tight fit with the chain body 100, thus satisfying the practicality and aesthetics of jewelry wearing. The spring chain clasp can be multiple or a single one, such as... Figure 5 and Figure 6 As shown.

[0035] The first head-making accessory 1 is a cylindrical structure with a solid bottom at its right end. A head-making nail 12 extends horizontally from the center of this solid bottom end. The head-making nail 12 is cylindrical in shape, with an annular groove 11 in the middle of the cylinder. A cone extends from the rightmost end of the head-making nail 12, with the cone tip pointing to the right. The annular groove 11 on the head-making nail 12 is used to engage with the spherical top surface of the subsequently installed gold nail 15. The left end of the first head-making accessory 1 has two connecting chain bodies, symmetrically distributed on the left end of the cylindrical body, used to connect with the chain body 100 accessory on the chain body 100.

[0036] The second head-making accessory 2 is composed of three cylinders of different sizes, thicknesses, and lengths connected in sequence, from left to right: a first cylinder, a middle cylinder, and a third cylinder. The first cylinder is the smallest, and three first through holes 14 are evenly distributed circumferentially on its outer ring, with equal included angles between any two adjacent first through holes 14. A second through hole 5 is provided on the right end face of the first cylinder, communicating with the three first through holes 14, for accommodating the insertion of the head-making pin 12 and engaging with the gold pin 15. The middle cylinder has a larger diameter and length than the first cylinder, and its cylinder wall is thinner, providing space for the installation of components such as the gold pin 15 and the spring 4. The diameter of the third cylinder is equal to that of the first head-making accessory 1. Two second connecting chain bodies are provided on the right end of the third cylinder. The first head-making accessory 1 also has two first connecting chain bodies for connecting to the chain body 100. The number of connecting chain bodies depends on the connection points on the chain body; therefore, this embodiment uses two connecting chain bodies, but in practice, there can be multiple.

[0037] Three sets of springs 4 and gold nails 15 are installed at the first cylindrical part of the second head fitting 2. Each set of springs 4 and gold nails 15 cooperate with each other and are respectively installed in three first through holes 14. Taking one set as an example, the gold nail 15 includes a top spherical part 6, a middle circular part 7, and a tail cylindrical part 8. The top spherical part 6 can pass through the second through hole 5 and engage with the annular groove 11 of the head fitting 12 on the first head fitting 1. The middle circular part 7 is engaged in the first through hole 14, and the tail cylindrical part 8 extends to the left. The spring 4 is sleeved on the tail cylindrical part 8 of the gold nail 15. The length of the spring 4 in the free state is greater than the length of the tail cylindrical part 8 of the gold nail 15. When the gold nail 15 and the spring 4 are installed between the first through hole 14 and the second through hole 5 of the second head fitting 2, the spring 4 is in a compressed state, so that the gold nail 15 always maintains a tendency to push to the right under the elastic force of the spring 4, thereby making the top spherical part 6 of the gold nail 15 engage with the annular groove 11 on the head nail 12 to achieve the locking function of the buckle.

[0038] After the three sets of gold nails 15 and springs 4 are installed, they are all in the pre-compression state of springs 4, so that the gold nails 15 always maintain the tendency to be engaged with the head nails 12, so as to ensure that the buckle device can be safe and stable during wearing and is not easy to fall off due to external pulling, thereby improving the safety performance of the buckle.

[0039] A circular sleeve 13 is fitted over the second head fitting 2. The circular sleeve 13 is a cylindrical structure. The circular sleeve 13 is fitted over the second head fitting 2 from left to right, so that the circular sleeve 13 covers the outside of the first cylinder, thereby limiting and protecting the gold nail 15 and the spring 4, preventing the gold nail 15 and the spring 4 from loosening or shifting during long-term use, and improving the overall reliability and durability of the device.

[0040] During assembly, the head pin 12 of the first head fitting 1 is inserted into the second through hole 5 of the second head fitting 2, and the first head fitting 1 and the second head fitting 2 are aligned. At this time, under the action of the spring 4, the top spherical parts 6 of the three gold nails 15 are respectively engaged in the annular grooves 11 on the head pin 12, so that the buckle is locked. When it is necessary to unlock the buckle, by pressing the first cylinder on the outside of the second head fitting 2 corresponding to the gold nail 15, the three gold nails 15 are pushed back to the left against the spring 4, and the top spherical parts 6 are disengaged from the annular grooves 11 of the head pin 12, thus unlocking the buckle.

[0041] This device can be equipped with two or more connecting bodies on the first head fitting 1 and the second head fitting 2 according to the different styles of chain body 100, so as to meet the needs of two-lobed, three-lobed or four-lobed chain body 100 styles, thereby enhancing the applicability of this device to different chain bodies 100.

[0042] This utility model also provides a piece of jewelry, which includes a chain body 100 and the aforementioned spring chain clasp. The spring chain clasp is connected to both ends of the chain body 100 via a connecting chain body, thereby closing the jewelry chain body 100 and meeting wearing requirements. This spring chain clasp device has advantages such as reliable and safe locking, convenient and flexible operation, strong aesthetics, and compatibility with various chain bodies 100, and can be widely used in the field of connection and fastening of various high-end jewelry chains.

[0043] This utility model utilizes the elasticity design of multiple sets of springs to greatly enhance the safety of the fastening, so that the jewelry remains stable when subjected to external pulling force.

[0044] The simple snap-fit ​​mechanism between the gold nail and the groove of the head fitting greatly reduces the difficulty of operation; users can open and close the device simply by pressing or rotating it.

[0045] The design of the connecting body at both ends of the buckle accessory, which matches the chain body, not only improves the compatibility with different chain body styles, but also enhances the overall appearance coordination and sense of sophistication of the jewelry.

[0046] Due to the precise fit between the components, the device has better tensile strength and durability during use, reducing the need for frequent maintenance or replacement;

[0047] This invention not only overcomes the shortcomings of existing buckle-making methods in terms of safety and convenience, but also takes into account aesthetics and practicality, greatly improving the overall performance of jewelry and user experience.

[0048] 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.
