Description

BACKGROUND OF THE INVENTION

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 INVENTION

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.
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.

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.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1, the user-friendly jewelry chain of the present invention comprises a chain 1, at least one charm 2, at least one stop ring 3 which can be fixed on the chain 1 and a clasp. The stop ring 3 is provided with a flexible positioning component 7. As shown in FIGS. 8, 9 and 10, the centre of the end face of stop ring 3 is provided with or opened with a perforation 31. The perforation 31 is in a shape which allows the chain 1 to pass through, and the perforation 31 has a diameter slightly larger than the cross sectional diameter of the chain 1, so that the stop ring 3 can be easily and freely strung onto the chain 1. As shown in FIGS. 2 to 7, the charm 2 is provided with a positioning through-hole 21 which allows the chain 1 and the stop ring 3 to pass through. As shown in FIG. 1, the charm 2 is sleeved on the stop ring 3, and the charm 2 is fixedly positioned on the stop ring 3 by the flexible positioning component 7 acting on a hole wall of the positioning through-hole 21. When the charm 2 is strung onto the present invention, by pushing the charm 2 and thereby compressing the flexible positioning component 7 of the stop ring 3, the charm 2 can pass through the stop ring 3 and be strung onto the chain 1.
As shown in FIGS. 1 and 11, the clasp comprises a male end 4, a female end 5, a locking sleeve 6, a flexible pin component 8 and a flat spring component 9. The female end 5 is connected to one end of the chain 1. As shown in FIG. 12, the flexible pin component 8 and the flat spring component 9 are respectively mounted on the female end 5. As shown in FIGS. 14, 15 and 16-1, the locking sleeve 6 is of a hollow structure, and a pin slot 10 and a flat spring slot 61 are formed inside one end of the locking sleeve 6. The pin slot 10 comprises horizontal slots 101 and a vertical slot 102, and the horizontal slots 101 and the vertical slot 102 are interlinked. As shown in FIGS. 20 and 21, the female end 5 is sleeved into one end of the locking sleeve 6. The flexible pin component 8 on the female end 5 enters from the horizontal slots 101 and slides into the vertical slot 102 along the horizontal slots 101. Rotation of the locking sleeve 6 causes the flexible pin component 8 to act on a slot wall of the vertical slot 102 and the flat spring component 9 on the female end 5 to embed into the flat spring slot 61 of the locking sleeve 6 and act on a slot wall of the flat spring slot 61, so that the chain 1, the female end 5 and the locking sleeve 6 are assembled together. The flat spring component 9 on the female end 5 acts on the flat spring slot 61 to achieve locking in horizontal direction, and the flexible pin component 8 on the female end 5 acts on the vertical slot 102 of the pin slot 10 to prevent the female end 5 from detaching due to rotation of the locking sleeve 6 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.
To make the structure of the present invention more reasonable, as shown in FIGS. 2 to 6, the positioning through-hole 21 of the charm 2 is formed by an inner annular slot 22 and a positioning ring 23 disposed at each of two ends of the inner annular slot 22. The flexible positioning component 7 acts on a slot wall of the inner annular slot 22 of the positioning through-hole 21, so that the stop ring 3 of the present invention can enter from the positioning ring 23 at one end of the charm 2, then the flexible positioning component 7 of the stop ring 3 can restore to its original state in the inner annular slot 22 so that the charm 2 can be sleeved on the stop ring 3 and will not detach from the stop ring 3 except by human action.
To moderate the amplitude of swing of the stop ring 3 in the positioning through-hole 21, as shown in FIGS. 2, 4, 5 and 7, positioning blades 24 are also provided on the inner annular slot 22 of the positioning through-hole 21. The positioning blades 24 encircle the positioning ring 23 and are evenly distributed along the inner annular slot 22.
To make the structure of the present invention more reasonable and further optimize its positioning effect, as shown in FIG. 12, the flexible pin component 8 comprises two flexible pins 81, and the two flexible pins 81 are symmetrically mounted on the female end 5.
To make the structure of the present invention more reasonable and further optimize its positioning effect, as shown in FIG. 12, the flat spring component 9 comprises two flat springs 91. As shown in FIG. 17, each of the flat springs 91 has one end which forms a mounting portion 92 and another end which bends to form a flexible snap portion 93. The two flat springs 91 are symmetrically mounted on the female end 5 through their respective mounting portions 92. As shown in FIG. 21, when the female end 5 of the present invention is sleeved into the locking sleeve 6, the flexible snap portions 93 of the flat springs 9 act on the flat spring slot 61 of the locking sleeve 6 so as to secure the female end 5 in the locking sleeve 6.
To make the structure of the present invention more reasonable, as shown in FIG. 15, one end of the locking sleeve 6 is provided with the pin slot 10 and the flat spring slot 61. The pin slot 10 is formed by two horizontal slots 101 and a vertical slot 102. The vertical slot 102 and the flat spring slot 61 are annular slots along an inner periphery of the locking sleeve 6. The two horizontal slots 101 are symmetrically arranged and pass through the flat spring slot 61 respectively to interlink with the vertical slot 102. By means of this design, no matter how the locking sleeve 6 is rotated, even if the flexible pin component 8 aligns with the horizontal slots 101 by chance, the female end 5 still cannot detach from the locking sleeve 6 under the effect of the flat spring component 9. Similary, when the flat spring component 9 aligns with the horizontal slots 101, under the effect of the flexible pin component 8, the female end 5 cannot detach from the locking sleeve 6. Only when the flexible pin component 8 aligns with the horizontal slot 101 and a certain pulling force is exerted could the flat spring component 9 be compressed and thereby allowing the flexible pin component 8 to slide out along the horizontal slots 101. Besides, under the effect of the pulling force, the flat spring component 9 is detached from the flat spring slot 61, which makes the female end 5 detach from the locking sleeve 6. To embed the flat spring component 9 on the female end 5 of the present invention into the flat spring slot 61, as shown in FIGS. 14 and 15, the locking sleeve 6 is provided with shallow slots 64 which allows the passage of the flat spring. The shallow slots 64 and the annular slot forming the flat spring slot 61 are interlinked.
As shown in FIGS. 15, 16 and 16-1, an interlinking part of the horizontal slots 101 and the vertical slot 102 is provided with four slots 103 which are distributed in a cross shape in the vertical slot 102. With the slots 103, when the flexible pin component 8 of the present invention slides from the horizontal slots 101 into the interlinking part of the horizontal slots 101 and the vertical slot 102, the flexible pin component 8 cooperates with the slots 103 to make noises and stop the flexible pin component 8 from sliding into the vertical slot 102 in one go. The user needs to apply force slightly to retract the flexible pin component 8 from the slots 103 and enter the vertical slot 102. Ultimately the flexible pin component 8 is embedded into the slots 103 in the vertical slot 102, making noises to inform the user that the female end 5 has already been secured in the locking sleeve 6. With this design, the user can precisely know the sliding track of the flexible pin component 8.
To make the structure of the present invention more reasonable, as shown in FIGS. 11 and 21, the present invention further comprises a fixed ring 20 and a jewelry chain connector 30. As shown in FIG. 13, one end of the jewelry chain connector 30 is provided with a jewelry chain connecting slot 40, and the jewelry chain connector 30 is connected by the jewelry chain connecting slot 40 to one end of the chain 1.
