[0002] A pendant is a type of jewelry worn around the neck, mostly made of metal, such as stainless steel or silver, but also sometimes made of minerals, crystals, or jade. To enhance their aesthetic appeal, pendants often mimic the shapes of existing objects and incorporate movable parts, such as imitating the opening and closing of a lotus flower, revealing the decorative elements inside when open. However, traditionally, the opening and closing of the petals in these pendants is achieved by adding a pin at the bottom; the petals rotate around the pin to open and close. Because the petals and pin are separate structures and small in size, the assembly process is time-consuming and labor-intensive, difficult to standardize, and affects production speed and costs.

[0003] Therefore, how to provide a pendant with an opening and closing structure to improve the convenience and efficiency of pendant production and assembly has become an urgent technical problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a pendant with an opening and closing structure, thereby improving the convenience and efficiency of pendant production and assembly.

Detailed Implementation

[0037] This utility model embodiment provides a pendant 100 with an opening and closing structure, which solves the technical problem that the opening and closing function of the petals in the prior art is achieved by adding a pin to the bottom. Since the petals and the pin are separate structures and small in size, it is very time-consuming and labor-intensive in the production and assembly process. This invention achieves the technical effect of greatly improving the convenience and efficiency of pendant production and assembly.

[0038] The technical solution in this embodiment of the utility model is to solve the above problems. The overall idea is as follows: the petal opening and closing part 4 is secured to the inner side of the groove 11 of the lotus ornament 1 by the protruding nail 42, and the rotating part 41 of the petal opening and closing part 4 is embedded in the petal slot 32 of the petal linkage part 3. The base 2 is installed on the lotus ornament 1 to limit the petal opening and closing part 4. The petal linkage part 4 is raised and lowered by the rotation of the lower screw 5 under the limit of the guide post 21, thereby linking the petal opening and closing part 4 to open and close. Since the petal opening and closing part 4, the rotating part 41, and the protruding nail 42 are integrated structures, the entire petal opening and closing part 4 can be grasped and the lower end can be embedded in the corresponding position. There is no need to operate the small-sized pin as in the traditional way, so as to improve the convenience and efficiency of the production and assembly of the pendant 100.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Please refer to Figures 1 to 4 As shown, a preferred embodiment of the present invention, a pendant 100 with an opening and closing structure, includes:

[0041] A lotus flower ornament 1 has a hollow structure with several grooves 11 around its top edge and several limiting holes (not shown) inside from top to bottom; the grooves 11 are used for the installation and limiting of the petal opening and closing parts 4; the limiting holes are used for the limiting installation of the base 2.

[0042] A base 2 has several guide posts 21 at its bottom, and each guide post 21 extends downward to a limiting rod 211 that matches the limiting hole. The base 2 is installed on the top of the lotus ornament 1 through the limiting rod 211 and the limiting hole. The limiting rod 211 and the limiting hole are interference fit. The guide post 21 serves as the guide rail for the petal linkage 3.

[0043] A petal linkage component 3 is located at the bottom end of the base 2. The outer wall has several vertical sliding grooves 31, which are slidably connected to the guide post 21. A petal locking groove 32 is arranged around the middle of the outer wall. The petal linkage component 3 is used to link each petal opening and closing component 4 to open and close synchronously through the petal locking groove 32.

[0044] Several petal opening and closing components 4 are provided. Each petal opening and closing component 4 has a rotating part 41 extending downward from its bottom end. A symmetrical protruding nail 42 is provided on both sides of the rotating part 41.
