A limiting plate 14 is arranged on the locking groove 11, so that a limiting groove 15 is formed among the limiting plate 14, the bottom plate 111 and the side wall 112; the notch 16 is formed in the limiting plate 14, the protrusion 22 on the snap ring 21 can enter the limiting groove 15 through the notch 16, so that the protrusion 22 is connected to the clamping block 13 in a sliding manner in the limiting groove 15 in a sleeving manner, and the protrusion 22 can be clamped in the limiting groove 15 after the cover plate 12 is opened, so that the snap ring 21 is continuously limited in the limiting groove 15, and if the first lock catch 1 and the second lock catch 2 are required to be disconnected, the protrusion 22 on the snap ring 21 needs to be slid to the notch 16, thereby avoiding the snap ring 21 from falling off the lock catch groove 11 under the pushing of no external force.

The following describes the present embodiment in detail, a latch structure, including a first latch 1 and a second latch 2, where the first latch 1 includes a latch slot 11 and a cover plate 12, the latch slot 11 includes a bottom plate 111 and two side walls 112 disposed on the bottom plate 111, and the cover plate 12 is hinged to one of the side walls 112, so that the cover plate 12 can be fastened to the latch slot 11 to block the notch of the latch slot 11. The cover plate 12 is fixed in the locking groove 11 in the prior art, and will not be described in detail. The clamping block 13 is arranged at one end of the bottom plate 111 of the locking groove 11, the second lock catch 2 comprises a clamping ring 21, the clamping ring 21 can be sleeved on the clamping block 13, when the clamping ring 21 is clamped on the clamping block 13, the cover plate 12 is used for covering, and therefore the clamping ring 21 can be limited. The two side walls 112 are provided with limiting plates 14 which are arranged opposite to the bottom plate 111, and the limiting plates 14 extend from one end of the side walls 112 to the other end; therefore, the limiting grooves 15 are formed among the limiting plates 14, the bottom plate 111 and the side walls 112, the notch of each limiting groove 15 is opposite, the two limiting plates 14 are provided with the notch 16, the two opposite sides of the clamping ring 21 are provided with the protrusions 22 corresponding to the notch 16, and therefore the protrusions 22 on the clamping ring 21 can enter the limiting grooves 15 through the notch 16 to limit. In this embodiment, the limiting plate 14 and the side wall 112 are integrally formed for easy manufacture.

Specifically, to ensure stability of the snap ring 21, the notch 16 and the latch 13 are located in different vertical planes. More specifically, the notch 16 and the clamping block 13 are located at two ends of the bottom plate 111, and the clamping ring 21 is convenient to install by adopting the structure, so that the clamping ring 21 and the clamping block 13 are prevented from interfering when the protrusion 22 passes through the notch 16. In order to make the two protrusions 22 smoothly enter the limit groove 15 through the notch 16 at the same time, the two notches 16 are symmetrically arranged, and it is understood that the protrusions 22 on the snap ring 21 are symmetrically arranged. So that as long as one of the protrusions 22 corresponds to the notch 16, the other protrusion 22 also corresponds to the notch 16, thereby enabling a reduction in the time for alignment of the two.

In this embodiment, the limiting plate 14 is disposed at the top end of the side wall 112 away from the bottom plate 111, and the distance between the upper end surface of the limiting plate 14 and the bottom plate 111 is the same as the height of the snap ring 21, so that the cover plate 12 can be ensured to be normally covered, and the snap ring 21 can be further prevented from shaking in the limiting groove 15 after the cover plate 12 is covered, so that the snap ring 21 is more stable. More specifically, since the notch 16 and the clamping block 13 are located on different vertical planes, the protrusion 22 enters the limiting groove 15 and needs to move to the clamping block 13 in the limiting groove 15, and therefore, the limiting plate 14 is parallel to the bottom plate 111, so that the sizes of the positions of the limiting groove 15 can be kept consistent, and the protrusion 22 can move in the limiting groove 15 more smoothly. Further, the protrusion 22 is a cylindrical protrusion, and an end of the protrusion 22 remote from the snap ring 21 is rounded. By adopting the structure, the protrusions 22 can pass through the gaps 16 more smoothly on one hand, and can slide in the limit grooves 15 more smoothly on the other hand, so that the blocking phenomenon is avoided. Here, the size of the limit groove 15 needs to be slightly larger than the size of the protrusion 22 to enable the protrusion 22 to rotate in the limit groove 15. In order to facilitate the installation of the chain, the first lock catch 1 comprises a first mounting ring 17, and the first mounting ring 17 is arranged at one end of the lock catch groove 11 far away from the clamping block 13; the second shackle 2 comprises a second mounting ring 23, the second mounting ring 23 being arranged at the end of the snap ring 21 remote from the protrusion 22.

The embodiment also provides a decorative chain, which comprises a chain and further comprises the lock catch structure, wherein one end of the chain is connected with the first lock catch 1, and the other end of the chain is connected with the second lock catch 2. More specifically, one end of the chain is connected to the first mounting ring 17 and the other end of the chain is connected to the second mounting ring 23.
