Description

[Technical Field]

[0001] This utility model relates to the field of jewelry technology, and in particular to the field of matching and connecting structures for jewelry cords and chains. [Background Technology]

[0002] As living standards continue to improve, people's enthusiasm for jewelry products is also rising, and their requirements for jewelry categories and aesthetics are becoming more and more diversified. Necklaces, bracelets and earrings are among the most common types of jewelry, and they have always been loved by consumers of all levels and ages, becoming major consumer products.

[0003] For jewelry such as bracelets, necklaces, and cords, there are styles with fixed, inseparable connections, as well as styles that open and close using movable clasps. The oldest connection method is the lobster clasp. With the development of precision hardware processing or precious metal processing technology, various types of clasp structures have gradually emerged, including snap clasps, rotating locking clasps, and press-fit clasps, among other connection devices with different structures and matching methods. Considering the current technical requirements, the structures used in jewelry need to be small in size and have high reliability requirements, making structural design quite difficult. Moreover, since the clasps used in jewelry are high-frequency opening and closing components, there are many related requirements regarding their fatigue limit and ease of wearing.

[0004] Currently, common clasps on the market have simple structures. For example, snap-on clasps can become loose after repeated opening and closing, leading to the risk of them accidentally coming loose and falling off. Magnetic clasps are also prone to loosening if accidentally hooked, as the magnetic part may be forced open. Hinged clasps, on the other hand, create a large protrusion at the hinge, reducing the smoothness of the jewelry chain and affecting the wearer's experience. Furthermore, the connection points in these methods are often weak points in the jewelry, making them susceptible to loosening or breakage due to friction and wear during use. To address these issues, a simple yet highly reliable connection structure needs to be designed. [Summary of the Invention]

[0005] This utility model addresses existing problems by proposing a connection structure suitable for jewelry cord chains. It is used to set and connect to both ends of the jewelry cord chain, allowing for easy opening and closing to complete the wearing process. At the same time, it needs to have a simple structure, low manufacturing cost, good reliability and safety, and maximize structural stability to avoid loosening or breakage caused by aging and wear.

[0006] The present invention relates to a press-type jewelry connection structure, comprising a central shaft and connecting end pieces, wherein the connecting end pieces are connected to both ends of a chain. The key feature is that a fixed connecting end piece is fixedly installed within the central shaft, while a movable connecting end piece is movably inserted into the central shaft. Holes and slots are provided on both end faces of the central shaft, and a movable press button is provided on the central shaft. The button is connected to the central shaft via a fulcrum in the middle, with one end being a latching end that latches onto the movable connecting end piece and the other end being a pressing end. A latching groove is provided at the corresponding position of the pressing end, connecting to the hole and slot. The latching end engages with the latching groove to latch the movable connecting end piece. A reset element is provided between the pressing end of the button and the central shaft, providing a reset force to push the pressing end outwards.

[0007] The slots on the end face of the central shaft are coaxial with the axis of the central shaft. The slots corresponding to the movable connecting end pieces are the first slots, and the slots corresponding to the fixed connecting end pieces are the second slots.

[0008] A snap-fit ​​groove is provided on the first slot, the snap-fit ​​groove passing through the space where the first slot and the button are located. Two limiting holes are provided on the second slot, the axial direction of the limiting holes being perpendicular to the axial direction of the second slot.

[0009] The movable connecting end piece is provided with a head end and a locking groove at the part inserted into the central shaft. When the locking groove is inserted into the first hole groove, the locking groove corresponds to the position of the snap-fit ​​groove. The snap-fit ​​end of the button has a snap hook, which extends into the snap-fit ​​groove to lock the locking groove and achieve the locking of the movable connecting end piece.

[0010] The fixed connection end piece has an end cap and a locking groove at the part fixed to the central shaft. When the fixed connection end piece is placed into the second hole groove, two locking pins are inserted into the limiting hole.

[0022] Example 1:

[0023] Please refer to the attached document. Figure 1 and attached Figure 2 The illustration shows a push-button jewelry connection structure, which includes a central shaft 10 and connecting end pieces, wherein the connecting end pieces are connected to both ends of the chain / bracelet, and the chain / bracelet can be opened and closed by the cooperation of the connecting end pieces and the central shaft 10.

[0024] The fixed connecting end piece 21 is fixedly installed inside the central shaft body 10, while the movable connecting end piece 22 is movably inserted into the central shaft body 10. The central shaft body 10 has holes and slots on both ends, and a movable pressing button 30 is provided on the central shaft body 10. The button 30 is connected to the central shaft body 10 through a fulcrum in the middle. One end of the button 30 is a snap-fit ​​end 31 that snaps into the movable connecting end piece, and the other end is a pressing end 32. A snap-fit ​​groove 12 with a hole and slot is provided at the corresponding position of the pressing end 32. The snap-fit ​​end 31 snaps into the snap-fit ​​groove 12 to lock the movable connecting end piece 22. A reset member 40 is provided between the pressing end 32 of the button 30 and the central shaft body 10 to provide a reset force to push the pressing end outward.

[0025] When in use, the user usually presses down on the pressing end 32 to lift up the latch end 31. When the pressing end 32 is released, it is driven by the resetting force of the resetting member 40 pushing outward, so the pressing end 32 pushes up and the latch end 31 presses down.

[0026] The slots on the end face of the central shaft 10 are coaxial with the axis of the central shaft. The slots corresponding to the movable connecting end piece 31 are the first slots 41, and the slots corresponding to the fixed connecting end piece 32 are the second slots 42.

[0027] A latching groove 12 is formed in the first slot 41, and the latching groove 12 passes through the space where the first slot 41 and the button 30 are located. Two limiting holes 14 are formed in the second slot 42, and the axial direction of the limiting holes 14 is perpendicular to the axial direction of the second slot 42. In fact, the limiting holes 14 also need to be drilled through the second slot 42, and the two are partially connected.

[0028] The movable connecting end piece 22 has a head end 221 and a locking groove 222 at the insertion point into the central shaft 10. Essentially, it forms a relatively large head end 221, followed by a locking groove 222 whose diameter decreases towards the rear. When the locking groove 222 is inserted into the first hole 41, it corresponds to the position of the latching groove 12. The latching end 31 of the button 30 has a hook 311, which extends into the latching groove 12 to engage the locking groove 222, thereby locking the movable connecting end piece 22.

[0029] The fixed connecting end piece 21, which is fixed to the central shaft 10, has an end cap 211 and a locking groove 212. When the fixed connecting end piece 21 is inserted into the second hole 42, two locking pins 50 are inserted into the limiting hole 14. The locking pins 50 in the limiting hole 14 are simultaneously engaged in the locking groove 212 to limit the fixed connecting end piece 21. The two locking pins 15 are symmetrical with respect to the central axis, maintaining balance and stability under force and limiting. Structurally, this makes the connection more stable and reliable, less prone to loosening, and provides balanced force, reducing wear and extending service life.

[0030] The button 30 is connected to the central shaft 10 via a bracket bearing 50. A bearing hole 11 is provided in the central shaft 10. The bracket bearing 50 is locked and fixed in the central shaft 10 by screws 51, and the button 30 is mounted on the bracket of the bracket bearing 50 via a rotating shaft 34.

[0031] A reset hole 13 is provided near the bearing hole 11 on the central shaft body 10. The reset element 40 is a compression spring, which is inserted into the reset hole 13 to press the pressing end 32 of the button 30.
