They are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the utility model.

[0026] The terms "first," "second," "third," etc. are merely used to distinguish elements of similar nature and do not indicate or imply relative importance or a particular order.

[0027] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0028] Please refer to Figures 1-6 An embodiment of the present invention provides a combined jewelry clasp, including a first assembly 10 and a second assembly 20. The first assembly 10 has a locking rod 11 and a first limiting portion 12; the first assembly 10 and the second assembly 20 are respectively used to connect the two ends of the jewelry, and the second assembly 20 is provided with a locking groove 21 and a second limiting portion 22. The locking groove 21 is used to accommodate the locking rod 11, and the second limiting portion 22 is provided in the locking groove 21. When the locking rod 11 is inserted into the locking groove 21, the second limiting portion 22 cooperates with the first limiting portion 12 to fix the first assembly 10 and the second assembly 20 to connect the two ends of the jewelry to form a closed loop.

[0029] Specifically, most existing jewelry connection structures are designed solely for connection performance, lacking aesthetic appeal. These structures are often made very small to prevent the clasp from dominating the design. Consequently, conventional jewelry connection structures struggle to balance connection performance and design appeal. In contrast, in this embodiment, a locking rod 11 and a locking slot 21 secure the first and second components 10, 20 to connect the two ends of the jewelry. The combination of the locking slot 21 and the locking rod 11 conceals the connection between the first and second components 10, 20 within the overall structure of the combined jewelry clasp. Externally, the clasp can be perceived as a separate decorative element, leaving ample room for design. Furthermore, the aesthetic design of the jewelry connection structure can also increase the clasp's bulk or improve its material durability, thereby enhancing the combined jewelry clasp's connection stability and inherent strength. After the locking rod 11 and the locking slot 21 are inserted into place, the first limiting portion 12 provided on the locking rod 11 and the second limiting portion 22 provided in the locking slot 21 naturally correspond to each other and are connected, thereby completing the locking of the first assembly 10 and the second assembly 20, and the wearing process of the jewelry is also very simple.

[0030] In this embodiment, the first limiting portion 12 is formed in a groove 13 provided along the circumference of the locking rod 11 . The second limiting portion 22 includes at least one first protrusion 23 . The groove 13 is engaged with the first protrusion 23 .

[0031] Specifically, the engagement between the groove 13 and the first protrusion 23 can provide the jewelry wearer with a force feedback. When the engagement between the groove 13 and the first protrusion 23 is completed, the first protrusion 23 suddenly enters the groove 13. The wearer can feel the force generated by the collision between the metals to know whether the jewelry is worn successfully, thereby avoiding the loss of jewelry due to wearing errors.

[0032] Furthermore, the width of the first protrusion 23 is less than or equal to the single-sided clearance between the locking rod 11 and the locking slot 21. Preferably, when the locking rod 11 is inserted into the locking slot 21, the first protrusion 23 is spaced apart from the inner wall of the locking slot 21. Excessive distance between the first protrusion 23 and the inner wall of the locking slot 21 can easily cause the locking rod 11 to wobble within the locking slot 21 after the first protrusion 23 engages the groove 13, thereby affecting the connection stability of the combined jewelry clasp. Frequent metal collisions can also cause adverse effects such as damage or deformation of the jewelry. In some softer metal jewelry clasps, the first protrusion 23 can be slightly larger than the single-sided clearance between the locking rod 11 and the locking slot 21 to take advantage of the metal's inherent elasticity.

[0033] In this embodiment, the width direction of the groove 13 is along the axial direction of the locking rod 11 , the depth direction of the groove 13 is along the radial direction of the locking rod 11 , and the depth of the groove 13 gradually increases from both ends in the width direction to the middle.

[0034] Specifically, since the first protrusion 23 enters or exits the groove 13 from the end in the width direction of the groove 13, when the first protrusion 23 enters the groove 13 from one end of the groove 13, the depth of the groove 13 gradually increases, which has a guiding effect on the first protrusion 23, is beneficial to protecting the surface of the first protrusion 23 and reducing wear.

[0035] In this embodiment, there are two first protrusions 23 . The two first protrusions 23 are disposed opposite to each other in the locking slot 21 , and the opposite sides of the two first protrusions 23 are arc-shaped surfaces.

[0036] Specifically, similar to the arrangement in which the depth of the groove 13 gradually increases from its ends in the width direction toward the center, the curved surface of the first protrusion 23 also effectively guides the sliding movement of the first protrusion 23 and the groove 13. The two opposing first protrusions 23 are simultaneously engaged in the groove 13 to clamp the locking rod 11, further improving the relative fixation between the first assembly 10 and the second assembly 20.

[0037] In this embodiment, a third assembly 30 is further included. The second assembly 20 is further provided with two embedding grooves 26. The two embedding grooves 26 are respectively provided on both sides of the lock groove 21. The third assembly 30 includes a baffle 31, two limit blocks 32 and at least one second protrusion 33. The two limit blocks 32 are provided on opposite sides of the baffle 31. The second protrusion 33 is provided on at least one of the limit blocks 32. The baffle 31 is used to cover the lock groove 21. The two limit blocks 32 are used to be embedded in the two embedding grooves 26. The second protrusion 33 is used to engage with the groove 13.

[0038] Specifically, the third assembly 30 is used to cover at least a portion of the lock slot 21 in a visible manner. When the third assembly 30 covers and blocks the lock slot 21, the two limit blocks 32 are embedded in the two embedding grooves 26. At the same time, the baffle 31 rests on both sides of the lock slot 21 and blocks the lock slot 21. As the two limit blocks 32 fall into the embedding grooves 26, the second protrusion 33 falls into the first limit portion 12 formed by the groove 13. Furthermore, there are two second protrusions 33, which are arranged opposite to each other. Preferably, the second protrusions 33 are arranged one-to-one on the two limit blocks 32. Please continue to refer to Figure 4 The two first protrusions 23 and the two second protrusions 33 are arranged along the periphery of the locking rod 11 and together clamp the first limiting portion 12, which can further secure the first assembly 10 and the second assembly. After the third assembly 30 and the second assembly 20 are installed, they can be fixed together by welding.

[0039] In this embodiment, the first assembly 10 further includes a first decorative portion 14 and a first assembly portion 15 . The first assembly portion 15 is connected to one side of the first decorative portion 14 . The locking rod 11 is provided on the first assembly portion 15 . Preferably, the first assembly portion 15 is formed by the locking rod 11 .

[0040] In this embodiment, the second assembly 20 further includes a second decorative portion 24 and a second assembly portion 25 . The second assembly portion 25 is located inside the second decorative portion 24 , and the locking slot 21 is located in the second assembly portion 25 .

[0041] Specifically, the first decorative portion 14 and the second decorative portion 24 are both used to provide room for appearance design or material design, while the first combination portion 15 and the second combination portion 25 are used to connect the first assembly 10 and the second assembly 20, avoiding interference between the functionality and ornamental properties of the combination jewelry clasp, so that the combination jewelry clasp has both high-stability connection performance and a larger design space, thereby enhancing its market value.

[0042] In this embodiment, the second decorative portion 24 is annular, the first combination portion 15 and the second combination portion 25 are both long axis-shaped, the second decorative portion 24 and the second combination portion 25 are connected to form a "D" shape, the first decorative portion 14 has an arc segment 141 and an inclined segment 142, and the first decorative portion 14 and the first combination portion 15 are connected to form an "R" shape.

[0043] Specifically, the shapes of the letters "D" and "R" feature more arcs and fewer sharp angles. In this embodiment, the first and second assemblies 10 and 20 cut away the more prominent portions of the letters "D" and "R," resulting in smoother contours and preventing material loss due to impacts on the jewelry. Furthermore, the presence of more arcs or steeper slopes enhances visual aesthetics and distributes the pulling force during jewelry tugged, resulting in a smoother transition. Furthermore, the combination of the letters "D" and "R" represents the applicant's brand identity, further facilitating the marketing of jewelry products and increasing their commercial value.

[0044] In this embodiment, a connecting ring 40 is further included. The connecting ring 40 is used to connect jewelry. The connecting ring 40 is disposed on one side of the first assembly 10 along the radial direction of the locking rod 11 .

[0045] Specifically, the locking rod 11 is inserted into the locking groove 21 along its axial direction, so that the locking rod 11 lacks freedom in its radial direction. The connecting ring 40 is arranged on one side of the locking rod 11 in the radial direction. In this way, the pulling force of the jewelry on the first assembly 10 will be along the radial direction of the locking rod 11. Since the locking rod 11 is subjected to great resistance in its radial direction, the risk of the locking rod 11 easily falling out of the locking groove 21 is avoided.

[0046] With people's growing interest in fashion and the increasing diversification of jewelry consumption, the trend of stacking necklaces and multi-material necklaces featuring gold and pearls has swept the fashion world. However, wearing and removing multiple necklaces requires untying the necklaces, which is time-consuming and laborious. It also easily causes the necklaces to become skewed or tangled during wear. To address this issue, in this embodiment, multiple connecting rings 40 are provided, arranged axially along the locking rod 11. Preferably, the multiple connecting rings 40 are arranged with equal height and width.

[0047] Specifically, each connecting ring 40 is connected to a necklace jewelry separately. When multiple connecting rings 40 are set, multiple necklace jewelry can be superimposed and connected, avoiding the problems of multiple necklace jewelry being connected to the same ring, such as the necklace being skewed, entangled, and difficult to remove.

[0048] In this embodiment, the second assembly 20 is also provided with a connecting ring 40 . When the first assembly 10 and the second assembly 20 are fixed to each other, the connecting ring 40 on the second assembly 20 is symmetrically positioned with the connecting ring 40 on the first assembly 10 .

[0049] The combined jewelry clasp provided in this embodiment secures the first and second components 10 and 20 by inserting a locking rod 11 into a locking slot 21, thereby connecting the two ends of the jewelry. The first and second retaining portions 12 and 22 secure the two components to each other. The engagement of the locking rod 11 and the locking slot 21 conceals the locking components within the first and second components 10 and 20, allowing for more flexible design options for the exteriors of the first and second components 10 and 20, enhancing the aesthetic appeal of the jewelry without compromising the secure connection between the first and second components 10 and 20.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
