Description

CHAIN COUPLING RING FOR PERSONAL ORNAMENTS}

The present invention relates to a tall chain link consisting of a foldable coupling element, and more particularly, a small ring used to connect and release a tall chain such as a necklace, bracelet or mobile phone string, It is more securely fastened so as not to be detached from the connecting ring, and it is also possible to fold the binding of the upper plate and the lower plate constituting the connecting ring to the long chain linking ring to balance the ease of assembly work, the simplification of the structure and the beauty of the appearance. It is about.

In general, a variety of chains, such as necklaces, bracelets or cell phone straps that are widely used as personal accessories, have been proposed and used, and such chains are easily combined into a ring shape and worn on the body. And small connecting rings of various shapes are provided at both ends thereof to terminate and to harmonize with the chain.

Several long chain links have already been proposed. The Korean Utility Model Publication No. 93-3142, one of them, forms a locking jaw in the operating tool so that the spring holding the operating tool installed in the connecting ring does not fall out, so that the jewelry is not detached when the accessory is connected in the connecting ring. An example of a link is shown, which consists of two main elements: a spring-loaded actuator between the top and bottom plates that are identical in shape and structure and are separated from each other. In order to prevent separation of the operating hole after the insertion, the welding along the periphery of the upper cover and the lower cover is to be welded, at this time, the work efficiency is lowered due to the difficulty of matching the upper cover and the lower cover accurately for welding There is a problem, and also the welding area is opened, the jewelry (chain) and the operating port is separated, of course, Mothayeo smooth the appearance areas have been pointed out as the problem is not elegant Heb.

In addition, the Korean Utility Model Publication No. 90-1767 (name: long chain link ring) forms an opening lever and an opening lever on one side of the upper plate, and a spring cabinet with the inner peripheral grooves on the bottom. Form a hook hole at the root of the right side and the other side between the right side and the other end, and install another spring cabinet with the inner peripheral groove on the upper side, and the left side and the right side, staggering the top plate and the bottom plate. It is tangled with spring, and it is welded and opened and closed by opening / closing lever.

However, the above-mentioned long chain link ring joins two separate upper and lower plates without welding, and also connects the axial pins and the free protrusions and the hook holes to the lower plate, and the upper plates to the axial pins and the hanging wheels. Holes should be formed. In this case, when the small link is considered, the structure is complicated and the production cost is increased.

In addition, in the coupling of the upper plate and the lower plate, the upper plate rotates around the axis pin of the lower plate, as well as the hassle that it is necessary to press-fit the fingers of the upper plate to match the holes of the upper plate to the shaft pin and the rubbing protrusion of the lower plate. Since the right and left half rings are opened and staggered with each other, when they are used for a long time, the upper plate loosens the coupling force to the shaft pins of the lower plate, and the lower plate and the upper plate are separated by the external impact, thus failing to serve as a connecting ring. Is pointed out as a problem.

Therefore, while healing the conventional problems as described above, inexpensive long chain linkage in terms of cost, and in terms of reliability, long chain linkage that more reliably maintains the fastening state of the chain while simple structure and assembly It is preferable to provide.

Therefore, the object of the present invention is to prevent the detachment of the chain due to the opening of the connecting portion by folding the upper plate and the lower plate constituting the connecting ring, and also to provide a chain link ring for easy assembly work. The connecting ring is achieved by integrally molding the connecting portions of the upper plate and the lower plate having the same shape and folding and folding the connecting portions of the lower plate and the upper plate.

Another object of the present invention is to provide a long chain link ring for narrowing the width of the connecting portion of the upper plate and the lower plate constituting the connecting ring to bend flexibly when the upper plate and the lower plate is bonded.

Further objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.
