Abstract

The utility model aims to solve the technical problem that a necklace joint buckle is provided. The necklace joint buckle comprises a U-shaped ring and a suspension loop, wherein the U-shaped ring is connected by a connecting button, and the U-shaped ring rotates around the connecting button and can be closed to lock the suspension loop; opening ends of the U-shaped ring cooperate with each other; and when being closed, the U-shaped ring forms a closed ellipse or circle. Through nesting the suspension loop in the closed annular structure formed by the closed U-shaped ring, the wearing operation is simple and convenient, and at the same time the phenomenon of opening or breaking at the connection is effectively avoided.

Description

A kind of necklace joint clasp

Technical field

The utility model relates to a kind of connecting piece of jewelry, is specifically related to a kind of necklace joint clasp.

Background technology

Common necklace joint clasp mainly contains following several mode:

1, spiral connects: screw and nut are equipped with respectively in the two ends at necklace, when wearing, screw are threaded with nut.

This mode wearer is difficult to Self-operating when wearing, and screw and the easy filigree of nut twist askewly, and necklace itself also easily wrapping phenomena occurs because of the end rotation.

2, buckle connects: pin thread and box are equipped with respectively in the two ends at necklace, when wearing, pin thread and box grafting are fastened.

This mode is worn more convenient; but; often can occur the fastening place after repeatedly using and open or fasten the appearance of insecure phenomenon, if be used for the connection of precious metal or precious stone necklace, the appearance that necklace junction fracture easily occurs or lose phenomenon.

The utility model content

Deficiency for the prior art existence, technical problem to be solved in the utility model is to provide a kind of necklace joint clasp, in the closed ring structure that link is nested in the formation of U-loop fastening, wear easy and simple to handlely, effectively avoid simultaneously the junction to open or the appearance of phenomenon of rupture.

For solving the problems of the technologies described above, technical solution adopted in the utility model is, a kind of necklace joint clasp, and it comprises U-loop and link, and U-loop is connected by junction button, and U-loop rotates to fasten around junction button link is pinned.

Above-mentioned necklace joint clasp, its U-loop openend echoes mutually, forms occluded ellipse shape or circle when U-loop fastens.

Above-mentioned necklace joint clasp, its U-loop link is overlapped, is compressed by junction button.

Above-mentioned necklace joint clasp, its junction button are the hollow ring structure.

Above-mentioned necklace joint clasp, its U-loop link is overlapped, is connected by the junction button with spring.

Above-mentioned necklace joint clasp arranges the draw-in groove and projection that cooperatively interact on its U-loop, when U-loop fastened, draw-in groove and projection were fastened.

Above-mentioned necklace joint clasp, its U-loop tail end arrange the clamping ring that connects necklace.

The connected mode that the utility model adopts U-loop and junction button to cooperatively interact can form enclosing of sealing link is pinned, and can not come off; The U-loop openend echoes mutually, forms occluded ellipse shape or circle after fastening, and is convenient to wear, and is very attractive in appearance and can not scratch wearer's skin; The U-loop link is overlapped, is compressed by junction button, in junction button, spring is set simultaneously, facilitates the U-loop folding, and is connected firmly; The draw-in groove that on U-loop, setting cooperatively interacts is with protruding, and when U-loop fastened, draw-in groove and projection were fastened, and draw-in groove and projection cooperatively interact and more stablize with firm when making U-loop closed.

The utlity model has following advantage and useful technique effect:

1, the utility model project organization is reasonable, is connected firmly, and wears simple, convenient;

2, the utility model low production cost, result of use is good;

3, the utility model good looking appearance can also play certain decoration function when connecting necklace;

4, the utility model adopts the respective outer side edges hollow of draw-in groove and projection engagement to compress or with the junction button of spring, compares the necklace joint clasp of original spiral or plug in construction, more firm stable, longer service life.

The specific embodiment

As Fig. 1 and shown in Figure 2, a kind of necklace joint clasp of the present embodiment, it comprises U-loop 1 and link 2, and U-loop 1 is connected by junction button 3, and U-loop 1 rotates around junction button 3 and fastens, thereby link 2 is pinned; U-loop openend 4 echoes mutually, and U-loop 1 forms occluded ellipse shape or circle when fastening;

U-loop link 5 is overlapped, is compressed by junction button 3; Junction button 3 compresses U-loop for the hollow ring structure, and as shown in Figure 4, perhaps interior setting of junction button 3 fixed and the spring 6 of opening U-loop, as shown in Figure 3; The draw-in groove 7 and projection 8 that cooperatively interact are set on U-loop 1, and when U-loop 1 fastened, draw-in groove 7 was fastened with projection 8; U-loop 1 tail end arranges the clamping ring 9 that connects necklace.

As shown in Figure 5, the mode that the utility model adopts U-loop 1 and junction button 3 to cooperatively interact can form enclosing of sealing link 2 is pinned, and can not come off; U-loop openend 4 echoes mutually, forms occluded ellipse shape or circle after fastening, and is convenient to wear, and is very attractive in appearance and can not scratch wearer's skin; U-loop link 5 is overlapped, is compressed by junction button 3, and the interior spring 6 that arranges of junction button 3, facilitate U-loop 1 folding, and be connected firmly simultaneously; The draw-in groove 7 and the projection 8 that cooperatively interact are set on U-loop 1, and when U-loop 1 fastened, draw-in groove 7 was fastened with projection 8, and draw-in groove 7 and projection 8 cooperatively interact more stable and firm when making U-loop 1 closed.

During use, link 2 is enclosed within on U-loop 1, then U-loop openend 4 is fastened in opposite directions, thereby pin link 2, complete the connection at necklace two ends.

The above, only to preferred embodiment of the present utility model, be not to be that the utility model is done other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every the utility model scheme content that do not break away to any simple modification made for any of the above embodiments, equivalent variations and remodeling, still belongs to protection domain of the present utility model according to technical spirit of the present utility model.
