The charm is sleeved on the stop ring and fixedly positioned on the stop ring. The clasp has a male end, a female end, a locking sleeve, a flexible pin component and a flat spring component. The female end is connected to the chain; the flexible pin component and the flat spring component are respectively mounted on the female end. A pin slot and a flat spring slot are formed in the locking sleeve. The pin slot has horizontal slots and a vertical slot. The female end is sleeved into the locking sleeve. The flexible pin component and flat spring component of the female end respectively act on slot walls of the vertical slot and the flat spring slot.
The present invention relates to a chain ornament, particularly a jewelry chain ornament strung with charms.
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 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. The second method is providing a positioning portion in the stop ring, and a positioning through-hole on each of the charms which allows passage of the positioning portion of the stop ring at a predefined position. However, during assembly, this method requires alignment of the positioning through-hole at one end of the charm and the positioning portion of the stop ring to position the stop ring in the through-hole of the charm and then rotating the charm so that the positioning through-hole at another end of the charm aligns with the positioning portion of the stop ring before the charm can be passed through the stop ring to be strung onto the 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. Such clasp which secure two ends of the chain to form a closed-loop has the following disadvantages. 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.
BRIEF SUMMARY OF THE INVENTIONAn 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.
To achieve this, the present invention adopts the following technical proposal:
A user-friendly jewelry chain comprising a chain, at least one charm, at least one stop ring which can be fixed on the chain and a clasp, characterized in that the stop ring is provided with a flexible positioning component; the charm is provided with a positioning through-hole which allows the chain and the stop ring to pass through; the charm is sleeved on the stop ring, and the charm is fixedly positioned on the stop ring by the flexible positioning component acting on a hole wall of the positioning through-hole.
The clasp comprises a male end, a female end, a locking sleeve, a flexible pin component and a flat spring component; the female end is connected to one end of the chain; the flexible pin component and the flat spring component are respectively mounted on the female end; the locking sleeve is of a hollow structure, and a pin slot and a flat spring slot are formed inside one end of the locking sleeve; the pin slot comprises horizontal slots and a vertical slot, and the horizontal slots and the vertical slot are interlinked; the female end is sleeved into one end of the locking sleeve; the flexible pin component on the female end enters from the horizontal slots and slides into the vertical slot along the horizontal slots; rotation of the locking sleeve causes the flexible pin component to act on a slot wall of the vertical slot and the flat spring component on the female end to embed into the flat spring slot of the locking sleeve and act on a slot wall of the flat spring slot, so that the chain, the female end and the locking sleeve are assembled together.
The positioning through-hole of the charm is formed by an inner annular slot and a positioning ring disposed at each of two ends of the inner annular slot; the flexible positioning component acts on a slot wall of inner annular slot of the positioning through-hole.
Positioning blades are also provided on the inner annular slot of the positioning through-hole.
To make the structure of the present invention more reasonable, the pin slot of the present invention has three embodiments: First, one end of the locking sleeve is provided with a pin slot, and the pin slot comprises horizontal slots, a vertical slot and a locking slot; Second, one end of the locking sleeve is provided with two pin slots opposite to each other, and the pin slot comprises horizontal slots, a vertical slot and a locking slot; Third, one end of the locking sleeve is provided with a pin slot, and the pin slot comprises horizontal slots, a vertical slot and a locking slot; wherein the vertical slot is an annular slot along an inner periphery of the locking sleeve; a plurality of locking slots are evenly disposed in the annular slot, and the horizontal slots and the locking slot are interlinked.
To make the structure of the present invention more reasonable, the vertical slot is deeper than the horizontal slots. The locking slot is deeper than the vertical slot.
As the present invention adopts the aforesaid technical proposal, it can achieve the following technical effects:
(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.
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.
(2) The present invention makes use of the flexible pin component and the flat spring component, so that after rotating the locking sleeve, the flat spring component on the female end acts on the flat spring slot to achieve locking in horizontal direction; the flexible pin component on the female end acts on the vertical slot of the pin slot to prevent the female end from detaching due to rotation of the locking sleeve when worn. As a result, when a user wears the jewelry chain of the present invention, the clasp will not detach no matter how hard it is shaked.
