Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a chain ornament, particularly a jewelry chain ornament strung with charms.[0002]Jewelry chain product such as hand chain, necklace and so forth basically comprises a chain, charms strung onto the chain and a closed-loop clasp for securing two ends of the chain together. In order to allow the charms to be fairly distributed on the chain, a stop ring is generally used to separate the charms on the chain. There are two methods of separating the charms by means of the stop ring. One of the methods is providing an external screw thread on an outer surface of the stop ring and an internal screw thread in an assembly opening of each of the charms, and passing the charms through the stop ring and preventing the charms from passing the stop ring on their own by means of the external screw thread of the stop ring and the internal screw threads of the charms. However, this method requires multiple rotations of the charms during...

AI Technical Summary

Benefits of technology

[0003]An object of the present invention is to provide a user-friendly jewelry chain which is simple in structure, scientifically designed, capable of eliminating the need for alignment when mounting or adjusting the charms, convenient and quick to use, and equipped with a clasp with reliable positioning effect so that it will not be detached when worn.

[0011]As the present invention adopts the aforesaid technical proposal, it can achieve the following technical effects:

[0012](1) The present invention provides a flexible positioning component on the stop ring, and provides a positioning through-hole on the charm, so that when the charm is strung onto the chain, by pushing the charm and thereby compressing the flexible positioning component of the stop ring, the charm can pass through the stop ring and be strung onto the chain. Each of the charms is strung onto the chain accordingly. When a certain number of charms are strung onto the chain, one of the charms can be sleeved on the stop ring, so that the flexible positioning component on the stop ring can restore to its original state in the inner annular slot, thereby separating other charms. In the process of stringing, the charms of the present invention do not need to rotate several times like threads to pass the stop ring.

[0013]Besides, there is no need to provide positioning portions on the stop ring of the present invention to align with corresponding positioning portions of the charms when stringing the charms. Therefore, the present invention is more effective in assembling, more convenient in assembling, and more convenient to use. The flexible positioning component will not be worn out easily, thus having a longer lifespan.

Problems solved by technology

However, this method requires multiple rotations of the charms during assembly before the charms can pass through the stop ring, thus consuming much time and energy for assembly, and the productivity is low.

Screw threads are easily worn out while in use, reducing the lifespan of the jewelry chain.

This method requires the charm to be aligned with the stop ring for multiple times during assembly, thus assembly is inconvenient.

When in use, the positioning through-hole of the charm may accidentally align with the positioning portion of the stop ring so that the charm may pass through the stop ring on its own, thus user needs to pass the charm through the stop ring again, resulting in inconvenience in use.

First, the male end and the female end are not secured together securely and are easy to be detached.

Second, the structures of the male end and the female end are complicated and are not good for production.

Third, assembling and securing the male end and the female end involve a lot of steps, thus assembly is inconvenient.

In view of the aforesaid disadvantages now present in the prior art, it is very necessary to redevelop and redesign the clasp part of the jewelry chain.
