For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0041] For a jewelry chain formed by connecting multiple small circular rings in series, it is difficult to make significant changes in appearance due to its structural characteristics, that is, due to the structural limitation that multiple circular rings need to be connected in series with each other. Generally, the appearance of the jewelry chain can only be modified by designing the small circular rings into ovals, rounded rectangles, etc. Such modifications are similar and it is difficult to catch the user's attention.

[0042] In addition, when manufacturing and assembling a jewelry chain made of multiple small rings, a large number of metal wires of equal length are first processed, and then the metal wires are bent into rings using professional equipment, and multiple rings are connected in series to form a jewelry chain while the metal wires are bent into rings. It can be seen that the steps of manufacturing and assembling a jewelry chain made of multiple small rings are complicated and the cost is high.

[0043] After the jewelry chain is manufactured, the multiple small rings thereon are difficult to bend and disassemble by hand, and the hands may be easily scratched when the small rings are bent. Therefore, it is not convenient to adjust the length of the jewelry chain by increasing or decreasing the number of small rings.

[0044] Based on the above problems, the present application proposes a jewelry chain fastening assembly, which no longer adopts the traditional circular ring series connection form, but realizes the assembly between multiple fastening units by mutually engaging the fastening arms and the card interface between two adjacent fastening units. In this way, the appearance design of the main body of the fastening unit will not be restricted, and it can be set into various shapes as needed. In addition, the jewelry chain formed by the head-to-tail fastening of multiple jewelry chain fastening assemblies is completely different from the traditional circular ring series chain in appearance, giving people a unique and novel visual effect, which can better attract the attention of consumers. For the production and assembly of the jewelry chain fastening assembly, it is only necessary to process multiple fastening units, and then use manual or simple tools to stretch the fastening arm on one fastening unit to elastically deform it, and then snap it into the card interface on another fastening unit to complete the assembly. The whole process is easy to operate and the assembly cost is low. On this basis, when you want to adjust the length, you only need to remove the existing fastening unit or snap in a new fastening unit by stretching the card arm, and the user can easily and conveniently adjust it to the required length.

[0045] Specifically, see Figure 1 and Figure 2 , Figure 1 The structure of the jewelry chain buckle assembly after disassembly is shown in FIG. Figure 2 The structure of the jewelry chain fastening assembly provided by the embodiment of the present application after assembly is shown in the figure. As shown in the figure, the jewelry chain fastening assembly 100 includes at least two fastening units 110, and the fastening unit 110 includes a main body 111, and one end of the main body 111 extends outwards on two opposite sides to form a clamping arm 112, and the free ends 1121 of the clamping arms 112 on both sides are arranged facing each other, and the clamping arms 112 can be elastically deformed with respect to the main body 111 (such as Figure 2 The other end of the main body 111 is provided with a card interface 113 on two opposite sides. Figure 1 to Figure 2 In the changing process, the clamping arm 112 of one clamping unit 110 is clamped and connected with the clamping interface 113 of another clamping unit 110 by elastic deformation.

[0046] Figure 1 and Figure 2 The back side of the jewelry chain fastening assembly 100 is shown, that is, the side that contacts the human skin when worn. Figure 3 and Figure 4As shown, in the specific embodiment shown in the figure, the main body 111 and the clamping arm 112 of the same buckle unit 110 are an integrated structure, and the main body 111 adopts a mountain pattern armor shape, specifically, an armor-like shape composed of a three-pronged dart-like part in the middle and bent parts arranged on both sides thereof, and the main body 111 has sharp edges and a strong texture. It should be noted here that the shape shown in the figure does not constitute a limitation on the specific implementation method of the main body 111. In addition to the shape shown in the figure, the main body 111 can also be designed in shapes such as heart shape, petal shape, etc.

[0047] Considering that the body 111 is relatively large, if the body 111 is entirely configured as a solid structure, the jewelry chain formed by the jewelry chain buckle assembly 100 will be heavy, which may cause discomfort when worn. Figure 1 and Figure 2 As shown in the specific embodiment shown in the figure, the back side of the buckle unit 110 is hollowed out to form a cavity 114. This arrangement can effectively reduce the weight of the buckle unit 110. At the same time, because the back side contacts the human skin when worn, the cavity 114 will not affect the aesthetics of the jewelry when worn.

[0048] During assembly, the clamping arm 112 can be bent and stretched by directly applying force to it by hand, or a tool (such as a screwdriver, etc.) can be used to abut against the inner side of the clamping arm 112 and apply force outward to stretch the clamping arm 112 to form a Figure 1 and 3 As shown in the state, the stretched-out card arm 112 is then aligned with the card interface 113 on the other snap-on unit 110, and the card arm 112 is released, and the card arm 112 recovers its deformation and snaps into the card interface 113, presenting a Figure 2 and Figure 4 In the state shown, the jewelry chain buckle assembly 100 is formed.

[0049] As jewelry, since the buckle unit 110 is usually made of precious metal material, which has strong rigidity, in order to enable the clamping arm 112 to undergo elastic deformation without breaking, the clamping arm 112 can be set to be thinner, and can also be Figure 4 As shown in the figure, the radial dimension of the end where the clamping arm 112 is connected to the main body 111 is designed to gradually increase toward the main body 111 to enhance the structural strength of the connection between the clamping arm 112 and the main body 111.

[0050] The card interface 113 can be Figure 1 The opening of the through hole shown in the figure may of course also be the notch of a groove, which is not specifically limited here.

[0051] The jewelry chain fastening assembly 100 provided in the embodiment of the present application is formed by a plurality of fastening units 110, wherein the fastening arms 112 at the head and tail are fastened to the card interfaces 113, which is different from the conventional circular ring series connection form, has the advantages of novel appearance and unique design, and the plurality of fastening units 110 can be easily assembled or disassembled, with low assembly cost and convenient length adjustment.

[0052] In order to facilitate the snap-on assembly between the snap-on units 110, the present application further proposes an implementation method, specifically as follows: Figure 5 Front view and Figure 6 The structure of the two buckling units 110 when assembled as shown in the back view, the end corners of the main body 111 where the card interface 113 is located are provided with abutment slopes 1111, and one buckling unit 110 is used to abut and frictionally cooperate with the free end 1121 of the clamping arm 112 of the other buckling unit 110 through the abutment slope 1111 on it when it is engaged with the other buckling unit 110, so that the clamping arm 112 of the other buckling unit 110 is elastically deformed and gradually stretched (into a state of being) during the sliding process relative to the abutment slope 1111. Figure 5 and Figure 6 When the free end 1121 of the snap-in arm 112 of the other snap-in unit 110 slides to the snap-in interface 113 of the snap-in unit 110, the snap-in arm 112 recovers its elastic deformation and snaps into the snap-in interface 113 of the snap-in unit 110, forming a snap-in arm 112 of the other snap-in unit 110. Figure 7 Front view and Figure 8 The state shown from the back view.

[0053] In this embodiment, by providing abutment slopes 1111 at the two side end corners of one end of the main body 111 where the card interface 113 is located, when assembling and connecting the two snap-on units 110, there is no need for the user to directly apply force to the snap-on arm 112 to open it with their hands, nor is there any need to use tools to open the snap-on arm 112. Instead, it is only necessary to abut the free end 1121 of the snap-on arm 112 of one of the snap-on units 110 against the abutment slope 1111 of the other snap-on unit 110, and then squeeze the two snap-on units 110, so that the snap-on arm 112 can be opened and snapped into the card interface 113 under the force of the abutment slope 1111. The whole process is easy, labor-saving and convenient to operate.

[0054] Furthermore, in the process of assembling and connecting the two buckle units 110 by extrusion, in order to prevent the buckle arm 112 from tilting and slipping when sliding relative to the abutting inclined surface 1111 due to uneven force on the opposite sides of the buckle unit 110, the present application proposes an implementation method, which is described in detail in detail in detail. Figures 5 to 8As shown in the figure, one end of the main body 111 extends outward to form a docking column 1112, and the other end is recessed inward to form a docking notch 1113. After the snap-on arm 112 of one snap-on unit 110 is snap-connected with the card interface 113 of another snap-on unit 110, the docking column 1112 is inserted into the docking notch 1113.

[0055] like Figures 5 to 7 or Figures 6 to 8 In the process shown, during the process that the clamping arm 112 and the abutting inclined surface 1111 abut and slide relative to each other, the docking post 1112 gradually extends into the docking notch 1113, so that during the assembly and clamping of the two latching units 110, when the docking post 1112 and the inner wall of the docking notch 1113 abut against each other for limiting, the latching unit 110 where the clamping arm 112 is located is not prone to swinging and tilting upward or downward, thereby preventing the latching unit 110 where the clamping arm 112 is located from slipping.

[0056] In order to increase the stability of the engagement connection between two adjacent buckle units 110, the present application further proposes an implementation method. Figure 8 As shown in the figure, the main body 111 forms a cavity 114 on the inner side of the card interface 113, and the free end 1121 of the card arm 112 is provided with a card portion 1122 with an increased radial dimension. The card portion 1122 extends into the cavity 114 on the inner side of the card interface 113 by extrusion and forms a card connection with the inner wall of the card interface 113.

[0057] It should be noted that the cavity 114 formed on the inner side of the card interface 113 of the main body 111 can be a larger cavity opened on the back side of the main body 111 to reduce weight as mentioned in the above embodiment, or it can be just a small cavity opened on the inner side of the card interface 113, and there is no specific limitation.

[0058] The diameter of the card interface 113 can be set to be equal to or slightly smaller than the diameter of the clamping portion 1122 , so that the clamping portion 1122 can be smoothly squeezed into the card interface 113 and form a reliable clamping connection with the card interface 113 .

[0059] In this embodiment, a cavity 114 is provided on the inner side of the card interface 113 of the main body 111, and a snap-in portion 1122 with an increased radial dimension is provided at the free end 1121 of the snap-in arm 112, so that the snap-in portion 1122 can be squeezed into the cavity 114 on the inner side of the card interface 113 and can form a reliable snap-in connection with the inner wall of the card interface 113, thereby ensuring the stability of the two adjacent snap-in units 110 after being snap-connected.

[0060] Please refer again Figure 7 and Figure 8In some embodiments, the snap-on arm 112 of one snap-on unit 110 can rotate relative to the snap-on interface 113 of another snap-on unit 110 after being snap-connected. After the two snap-on units 110 are snap-connected, there is a gap 120 between the two facing ends, so that the two snap-on units 110 can rotate relative to each other by a predetermined angle.

[0061] By reserving a certain gap between the two opposite ends of two adjacent buckle units 110, the two can rotate relative to each other at a predetermined angle, so that when multiple buckle units 110 are connected in series, a complete annular jewelry chain can be formed for wearing.

[0062] Specifically, when the complete annular jewelry chain is a bracelet, anklet, etc., it is shorter, requires fewer buckle units 110, and the required rotation angle between two adjacent buckle units 110 is larger, so the gap reserved between two adjacent buckle units 110 needs to be designed to be larger. When the complete annular jewelry chain is a necklace chain, it is longer, requires more buckle units 110, and the required rotation angle between two adjacent buckle units 110 is smaller, so the gap 120 between two adjacent buckle units 110 can be designed to be smaller.

[0063] In order to hide the connection structure between the buckle units 110 and improve the aesthetics of the jewelry formed by the jewelry chain buckle assembly 100, the present application further proposes an implementation method, which is specifically referred to in Fig. 9 Split state and Fig.10 The jewelry chain buckle assembly shown in the connected state, as shown in the figure, the main body 111 has a shielding wall 1114 located on one side of the card interface 113, and the shielding wall 1114 is used to shield at least part of the card arm 112 that is engaged with the card interface 113, and to limit the rotation of the card arm 112 toward the side where the shielding wall 1114 is located.

[0064] Specifically, the shielding wall 1114 is arranged on the outside of the card interface 113, that is, when worn, the shielding wall 1114 is located on the side of the card interface 113 away from the human skin. This arrangement makes it impossible for people to observe the structure of the connection between the card arm 112 and the card interface 113 when wearing jewelry composed of the jewelry chain buckle assembly 100, thereby increasing the mystery of the jewelry.

[0065] Taking the annular chain jewelry composed of the jewelry chain buckle assembly 100 as an example, in every two adjacent buckle units 110 thereon, the clamping arm 112 needs to rotate toward the side away from the shielding wall 1114. Therefore, by setting the shielding wall 1114 to limit the rotation of the clamping arm 112 toward the side where the shielding wall 1114 is located, it can be ensured that some of the buckling units 110 will not rotate in the opposite direction when worn (the reverse rotation of the buckling unit 110 refers to the rotation of the clamping arm 112 in two individual adjacent buckling units 110 toward the side away from the human skin under shaking or other force conditions, which will cause the entire chain to form a significant visual difference here, and may pinch the human skin), ensuring comfort and aesthetics when worn.

[0066] like Figure 7 As shown, in some embodiments, the fastening unit 110 is mirror-symmetrical with respect to the first straight line A, wherein the first straight line A is parallel to the arrangement direction of the plurality of fastening units 110 .

[0067] By setting the buckling unit 110 as a mirror-symmetrical structure, it can be made more beautiful, and the force between two adjacent buckling units 110 is evenly distributed, and the overall structure is stable and reliable.

[0068] In some embodiments, the buckle unit 110 is made of precious metal material. Precious metal material has good processing performance and aesthetics, and can effectively enhance the visual effect of the jewelry composed of the jewelry chain buckle assembly 100.

[0069] According to another aspect of the embodiment of the present application, a chain jewelry is also provided, such as a bracelet, a necklace, an anklet, etc. For details, please refer to Fig.11 , the figure shows the structure of the chain jewelry. As shown in the figure, the chain jewelry 200 includes a plurality of jewelry chain buckle assemblies 100 provided by any of the above embodiments, and the head and tail clamping arms 112 and the clamping interfaces 113 of the plurality of jewelry chain buckle assemblies 100 are mutually clamped and connected to form a ring.

[0070] According to another aspect of the embodiment of the present application, a piece of jewelry is also provided. Fig.12 , the structure of the jewelry is shown in the figure. As shown in the figure, the jewelry 500 includes the chain jewelry 200 and the decoration 300 provided in the above embodiment, and the decoration 300 is arranged on the chain jewelry 200.

[0071] Specifically, the decoration 300 may be a gemstone, diamond, etc. inlaid and fixed on the buckle unit 110, or may be a metal decoration welded on the buckle unit 110, or may be a Fig.12 The pendant shown in FIG. 1 is hung on the buckle unit 110 by a chain, a lanyard, etc.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
