Necklaces, bracelets and earrings are the most common jewelry pieces, which have always been loved by consumers of all levels and ages and have become major consumer products.

[0005] For bracelets, bracelets and necklaces, there are styles with fixed connection structures that cannot be separated as a whole, and there are also styles that can be opened and closed through movable buckles. The most common chain buckles we see are elastic buckles or spring buckles, which are more common and traditional. These buckles have a single style and lack of shape changes. In addition, the elasticity will cause the spring to break and the buckle to break as the use time increases.

[0006] Locks with overly complex structures are inconvenient to use and are not easy for the wearer to open and close by themselves. If the structure is too simple, there is a concern that it may fail or accidentally open after being touched, causing the jewelry to fall or be lost. Therefore, we have researched and improved the jewelry connection locks to make it easier to open and close through a two-level structure and superimposed actions to perform a two-way confirmation opening and closing process, avoiding structural problems such as accidental touching and opening.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please refer to the attached Figure 1 and attached Figure 2 : It shows a rotating jewelry lock, including a central sleeve 10 and connecting pieces matched at both ends of the central sleeve, the two connecting pieces are a fixed connecting piece 21 and a movable connecting piece 22. Figure 1 What is shown in the figure is a finished product after assembly, so it also includes an outer sleeve body 30 arranged on the periphery of the central sleeve 10, the fixed connecting member 21 and the movable connecting member 22. The outer sleeve body can play the role of wrapping and protecting the internal structure and the external decoration.

[0028] A rotational clamping assembly 40 for movably locking and connecting the movable connecting member 22 is provided at one end of the middle shaft sleeve 10 that is docked with the movable connecting member 22. The rotational clamping assembly 40 and the end of the movable connecting member 22 that is matched with the middle shaft sleeve 10 have a lock tongue piece 221 that is rotatably clamped into the rotational clamping assembly 40. The outer side of the lock tongue piece 221 has a radially concave groove 222, and the rotational clamping assembly 40 has an inner hole 43, and a limiting ring piece 44 is provided in the circumferential direction of the inner hole. The limiting ring piece 44 has a notch 45 that allows the lock tongue piece to pass completely, and the lock tongue piece 221 is inserted through the notch 45 and rotated to clamp into the limiting ring piece 44 with the groove 22. The plug-in structure between the limiting ring piece 44 and the groove 222 on the lock tongue piece limits the axial freedom of the movable connecting member 22.

[0029] The movable connecting member 40 includes two assembled accessories, a ring piece limiter 41 and a rotation positioning member 42. From the assembly method point of view, the ring piece limiter 41 and the rotation positioning member 42 are both in the shape of circular sheets, and the two are fitted together. When the movable connecting member 40 is assembled as a whole to the end face of the middle shaft sleeve 10, the two cannot be loosened and disassembled, and have relative rotation freedom within a certain angle.

[0030] The inner hole 43 of the ring piece stopper 41 has a stopper ring piece 44, and the center of the rotation positioning member 42 has a rectangular through hole 421 adapted to the lock tongue piece 221. When the lock tongue piece 221 is inserted into the rectangular through hole 421 of the rotation positioning member 42, when the lock tongue piece 221 rotates, it naturally drives the rotation positioning member 42 to rotate. The outer circumference of the rotation positioning member 42 has a positioning protrusion 422, and the positioning protrusion 422 cooperates with the stopper 411 on the outer circumference of the ring piece stopper 41 to locate the position of the lock tongue piece 221 passing through the notch 45 and the position away from the notch 45.

[0031] The limiting ring piece 44 has two notches 45 symmetrically arranged at 180° on the inner hole 43 of the ring piece limiting member 42, and the corresponding outer sides of the lock tongue piece 221 have grooves 222, and the width of the grooves 222 is adapted to the thickness of the limiting ring piece 44, that is, when the lock tongue piece 221 is to be inserted into the ring piece limiting member 42, the lock tongue piece 221 can only be inserted into the notch 45 when the lock tongue piece 221 is positioned opposite to the notch 45. If it is not aligned, the center hole of the limiting ring piece 44 is smaller than the width of the lock tongue piece 221 and cannot be inserted smoothly.

[0032] When the lock tongue piece 221 passes through the notch 45, the lock tongue piece 221 can be rotated so that the groove 222 on the lock tongue piece 221 can be stuck in the limiting ring piece 44, and the lock tongue piece 221 can be rotated freely along the limiting ring piece 44. However, because the limiting ring piece 44 is stuck in the groove 222, the movable connecting piece 22 is locked and cannot be loosened in the axial direction.

[0033] The rotating positioning member 42 is in the shape of a disc with a rectangular through hole 421 in the middle, which is adapted to the size and shape of the locking tongue piece 221 of the movable connecting member 22. Positioning protrusions 422 are provided on both sides of the rectangular through hole 421. The positioning protrusions 422 are clamped by the stop position 411 on the ring piece limiting member 41 at the position aligned with the notch 45 and at two limiting positions at a perpendicular angle to the notch 45.

[0034] The role of the rotating positioning member 42 is to guide the lock tongue piece 221 to correctly face the two positions of "open" and "closed". The stopper 411 on the ring piece limiter 41 is a protrusion from the outer circumference toward the rotating positioning member 42. The stopper limits the rotation limit angle of the rotating positioning member 42 and also specifies two positions for smooth insertion and locking. The rotating positioning member 42 has a rectangular through hole 421. Once the lock tongue piece 221 of the movable connecting member 22 is inserted into the rotating positioning member 42, it is a process of driving the rotating positioning member 42 to rotate synchronously. The cooperation between the positioning protrusion 422 on the rotating positioning member 42 and the stopper 411 ensures that when the lock tongue piece 221 is in the first position, it is aligned with the notch 45 and can be inserted smoothly. After the rotation, the second position is to let the lock tongue piece 221 rotate 90°, which is 90° away from the notch position, which is equivalent to the most reliable locking position.

[0035] The rotating jewelry fastener also includes an outer sleeve body 30, which is sleeved outside the middle sleeve 10, and covers the middle sleeve 10 and the end-face matched fixed connector 21 and the rotating clamping assembly 40 from the outer cylindrical surface of the cylinder.

[0036] The fixed connection member 21 includes a connection neck 211 which is clamped in the middle sleeve 10 with rotational freedom.

[0037] The rotary jewelry lock involved in the utility model is a lock tongue piece on the movable connecting piece combined with a rotating positioning piece, which is snapped into a ring piece limiting piece, and the movable connecting piece is doubly limited by the limiting piece and the positioning piece to complete the connection and loosening process. The structure is simple and easy to operate, and at the same time, it is confirmed that the parts that are rotated into place and snapped into the limit are undertaken by two different parts. The structure and function are clear and the design is reasonable. It is convenient to use and avoids the structural problem of accidental touch and accidental opening.
