[0001] The utility model relates to a jewelry buckle, especially a sliding buckle. BACKGROUND

[0002] In recent years, with the economic development and the improvement of consumer purchasing power, the market scale of the jewelry industry is also booming. Consumers pay more and more attention to personalization and customization when choosing jewelry. However, the existing jewelry buckle is usually a fixed shape such as lobster clasp, S clasp, etc., which can easily cause the aesthetic fatigue of consumers; while the appearance of the sliding buckle can be set at will, and the sliding groove is not easy to be observed, which is more in line with the needs of consumers.

[0003] In the prior art, the sliding buckle for jewelry usually adopts the mode that the sliding groove, the hole and the buckle with the head size larger than the width of the sliding groove and smaller than the diameter of the hole are matched to realize the locking and opening of the sliding buckle. When the sliding buckle needs to be locked, the head of the buckle is inserted into the hole, and the rod part of the buckle slides on the sliding groove; the head size larger than the width of the sliding groove ensures that the buckle is located in the sliding groove, and the sliding buckle is in the locked state. However, in the actual use process, the rod part of the buckle often slides freely on the sliding groove, which leads to the accidental opening of the sliding buckle, causing the jewelry to fall off, and greatly affecting the reliability of the sliding buckle.

[0006] Optionally, the first component is in a cylindrical shape, and the strip-shaped opening is arranged on the circumference of the first component.

[0007] Optionally, the first component is provided with two strip-shaped openings, and the two strip-shaped openings are rotationally symmetrical with respect to the central axis of the first component.

[0008] Optionally, the second component is a closed-end cylindrical tube, and the protruding part is arranged at the closed end of the second component.

[0009] Optionally, the second component is connected with a jewelry chain or rope at the inner side.

[0010] Optionally, the second component is a cylindrical tube, and the protruding part is arranged at the distal end of the second component.

[0011] Optionally, the second component is connected with a jewelry chain or rope at the proximal end.

[0012] Optionally, the width of the strip-shaped opening near the end of the small hole is less than the width of the main body of the strip-shaped opening.

[0013] Compared with the prior art, the technical scheme provided by the utility model has the beneficial effects that: the technical means that the protruding part is composed of a first protruding section, a second protruding section and a third protruding section from the proximal end to the distal end, the radial dimension of the first protruding section is adapted to the width of the strip-shaped opening, the radial dimension of the second protruding section is adapted to the small hole, and the radial dimension of the third protruding section is adapted to the large hole; when the sliding buckle is locked, the third protruding section enters the large hole, the first protruding section slides on the strip-shaped opening, and the second protruding section is pulled out after reaching the small hole; the sliding buckle is locked while preventing the protruding part from freely sliding on the strip-shaped opening, jewelry falling caused by the sliding buckle being accidentally opened is avoided, and the reliability of the sliding buckle is greatly improved. The shape of the sliding buckle can be freely set, and the sliding buckle is more in line with the needs of consumers for personalized and customized jewelry. BRIEF DESCRIPTION OF DRAWINGS
