Abstract
Description
Technical Field
[0001] This utility model relates to the field of jewelry chain technology, and in particular to a zero-welding chain ornament. Background Technology
[0002] In the jewelry manufacturing industry, especially in chain ornaments, connection technology (mainly referring to the connection method between chain links) is a key factor determining the structural integrity, durability, aesthetics, and production cost of the product. For a long time, traditional chain ornament connection technologies have primarily relied on welding processes (such as spot welding and laser welding) or mechanical fasteners (such as interlocking links) to achieve permanent or movable connections between chain links. However, these traditional connection technologies have a series of significant drawbacks and limitations:
[0003] High production costs: The welding process between chain links typically requires skilled operators, specialized welding equipment (such as laser welders and spot welders), and specific consumables (such as solder and shielding gas). The manufacturing and assembly of mechanical fasteners also involve precision machining and manual operation. These factors collectively drive up the costs of raw materials, equipment depreciation, and labor, resulting in a persistently high overall production cost for chain ornaments.
[0004] Low production efficiency: Welding between chain links often requires processing each link or connection point individually, which is a relatively time-consuming process. Whether manual or semi-automatic welding, production speed is limited, making it difficult to meet the demands of large-scale, high-efficiency production. The assembly of mechanical fasteners also requires meticulous manual operation, resulting in a significant efficiency bottleneck.
[0005] Loose welds: The weld strength between the chain links weakens, gaps appear at the chain link connections, affecting the integrity and aesthetics of the chain ornament.
[0006] Impact on product lifespan and aesthetics: Loose or broken solder joints between chain links directly shorten the lifespan of the chain. Even without breakage, loose solder joints can cause the chain to deform or twist, reducing comfort when worn. Furthermore, solder joints are often difficult to completely conceal or perfectly conceal, potentially affecting the overall appearance of the chain. Utility Model Content
[0007] Therefore, it is necessary to provide a zero-welding chain ornament to address the aforementioned problems.
[0008] This application provides a zero-welding chain ornament, including chain body units and connecting cords;
[0009] The chain unit has multiple chain units, each having an assembly groove, a limiting part, and a threading hole. The connecting rope is sequentially threaded through the threading holes of the multiple chain units to connect them into a chain structure. Between two adjacent chain units, the assembly groove of the preceding chain unit is assembled and connected to the limiting part of the following chain unit.
[0010] This application discloses a zero-welding chain ornament, in which multiple chain units are connected into a chain structure by passing a connecting rope through the thread holes on all chain units, thereby forming a first connection; two adjacent chain units are assembled by the cooperation of the assembly groove and the limiting part to form a second connection, preventing misalignment between adjacent chain units; through the synergistic connection mechanism of the first and second connections, this application not only ensures the firmness of the connection of multiple chain units, but also eliminates the traditional welding process, simplifies the production process, and significantly reduces production costs.
[0011] In one embodiment, the mounting groove, the limiting part, and the threading hole on a single chain unit are coaxially arranged, with the threading hole extending from the mounting groove to the limiting part. By coaxially arranging the mounting groove, the limiting part, and the threading hole, and with the threading hole extending from the mounting groove to the limiting part, after the limiting part and the mounting groove are assembled and connected, the connecting cord is hidden inside multiple chain units. This makes the chain ornament of this application appear without any loose threads or connection marks, ensuring the smoothness and aesthetics of the chain ornament's appearance, and making the overall effect more natural.
[0012] In one embodiment, the number of assembly slots on a single chain unit is not less than two, and the number of limiting parts is the same as the number of assembly slots, with the not less than two assembly slots spaced apart. Because a single chain unit has at least two assembly slots and limiting parts, the assembly slots on the Nth chain unit and the limiting parts on the N+th chain unit form at least two sets of assembly structures; for example, a single chain unit has two assembly slots and two limiting parts, and the assembly slots on the Nth chain unit and the limiting parts on the N+th chain unit form two sets of assembly structures. Based on this, with at least two sets of assembly structures between adjacent chain units, not only can the integrity of the structure be maintained even if the assembly slots and limiting parts in one set of assembly structures accidentally separate, but multiple sets of assembly structures can also improve the tensile strength and torsional stiffness of adjacent chain units.
[0013] In one embodiment, the assembly groove has a circular cross-section, and the limiting part also has a circular cross-section. The limiting part is inserted into the assembly groove to achieve the assembly connection of two adjacent chain units. Since both the assembly groove and the limiting part have circular cross-sections, the limiting part does not require orientation alignment during insertion into the assembly groove, reducing the assembly difficulty. Furthermore, the cylindrical limiting part and the circular assembly groove assembly connection allow for uniform torque transmission through the circular contact surface, reducing stress concentration at the connection point and minimizing localized wear caused by asymmetrical shapes. Moreover, the aforementioned assembly connection provides a margin of movement for the relative displacement of two adjacent chain units, ensuring flexibility in movement between the two chain units.
[0014] In one embodiment, the length of the limiting portion is greater than the depth of the assembly groove. Because the length of the limiting portion is greater than the depth of the assembly groove, even when the limiting portion is fully inserted into the assembly groove, it is at least partially exposed between the gaps between two chain units. When the connecting cord strings multiple chain units together to form a chain structure, the limiting portion is still partially inserted into the limiting groove of the next chain unit, avoiding misalignment between adjacent chain units. Moreover, based on the above design, it can be ensured that the ends or connection points of the connecting cord are all hidden inside the chain units, ensuring the smoothness and aesthetics of the jewelry's appearance.
[0015] In one embodiment, the chain unit is further provided with an inlay groove, on which a decorative object is inlaid.
[0016] In one embodiment, there are multiple inlay slots, which are spaced apart. By providing multiple inlay slots, each slot can be inlaid with the same or different decorative items, allowing for customization to meet diverse customer needs.
[0017] In one embodiment, the chain unit has a contact surface and a decorative surface, the contact surface being planar and the transition between the contact surface and the decorative surface being rounded.
[0018] In one embodiment, the connecting rope is a high-strength rope. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.
[0028] The following describes some embodiments of the zero-welding chain ornament of the present invention with reference to the accompanying drawings.
[0029] like Figures 1 to 4 As shown, this embodiment discloses a zero-welding chain ornament, including a chain body unit 10 and a connecting rope 20;
[0030] There are multiple chain units 10. Each chain unit 10 has an assembly groove 101, a limiting part 102, and a threading hole 103. The connecting rope 20 is sequentially threaded through the threading holes 103 of the multiple chain units 10 to connect the multiple chain units 10 into a chain structure. Between two adjacent chain units 10, the assembly groove 101 of the previous chain unit 10 is assembled and connected to the limiting part 102 of the next chain unit 10.
[0031] The zero-welding chain ornament of this application connects multiple chain units 10 into a chain structure by passing a connecting rope 20 through the thread holes 103 on all chain units 10, thereby forming a first connection. Two adjacent chain units 10 are assembled by the cooperation of the assembly groove 101 and the limiting part 102 to form a second connection, preventing misalignment between adjacent chain units 10. Through the synergistic connection mechanism of the first and second connections, this application not only ensures the firmness of the connection of multiple chain units 10, but also eliminates the traditional welding process, simplifies the production process, and significantly reduces production costs.
[0032] The chain ornaments in this application can be necklaces worn around the neck, bracelets worn on the hands, or anklets worn on the feet.
[0033] The chain unit 10 can be made of metal or non-metal. For example, the chain unit 10 is made of a metal material such as silver, gold or copper alloy.
[0034] There can be multiple chain units 10, and the shape of each chain unit 10 can be the same or different. For example, all chain units 10 have a semi-circular cross-section.
[0035] Each chain unit 10 may have an assembly groove 101, a limiting part 102, and a threading hole 103. The assembly groove 101 of the Nth chain unit 10 can be fitted and assembled with the limiting part 102 of the (N+1)th chain unit 10. Radial limiting is achieved by matching the geometric shapes of the assembly groove 101 and the limiting part 102. The assembly connection between the assembly groove 101 and the limiting part 102 can be movably disassembled by means of a pin connection. It should be noted that in some embodiments, the assembly groove 101 and the limiting part 102 can also be connected by means of a buckle, hook, or elastic clip.
[0036] The connecting rope 20 can pass through the threading holes 103 of all chain units 10 in sequence to form an axial series structure, so as to provide tensile strength and prevent the chain units 10 from coming apart.
[0037] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the assembly groove 101, the limiting part 102 and the threading hole 103 on a single chain unit 10 are coaxially arranged, and the threading hole 103 extends from the assembly groove 101 to the limiting part 102.
[0038] The above embodiment further defines the assembly groove 101, the limiting part 102 and the threading hole 103 as being coaxially arranged, and the threading hole 103 extends from the assembly groove 101 to the limiting part 102. After the limiting part 102 is assembled and connected to the assembly groove 101, the connecting rope 20 is hidden inside the multiple chain units 10, so that the chain ornament of this application does not have visible thread ends or connection marks, ensuring the smoothness and aesthetics of the chain ornament's appearance, and making the overall effect more natural.
[0039] like Figure 1 , Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of assembly slots 101 on a single chain unit 10 is not less than two, and the number of limiting parts 102 is the same as the number of assembly slots 101, and the not less than two assembly slots 101 are distributed at intervals.
[0040] The above embodiments further limit the number of assembly slots 101 and limiting parts 102 of a single chain unit 10 to not less than two, and the assembly slots 101 on the Nth chain unit 10 and the limiting parts 102 on the N+1th chain unit 10 form not less than two sets of assembly structures; for example, the number of assembly slots 101 and limiting parts 102 of a single chain unit 10 is two, and the assembly slots 101 on the Nth chain unit 10 and the limiting parts 102 on the N+1th chain unit 10 form two sets of assembly structures; based on this, the two adjacent chain units 10 are connected by not less than two sets of assembly structures, so that even if the assembly slots 101 and limiting parts 102 in a certain set of assembly structures are accidentally separated, the remaining assembly structures can still maintain the integrity of the structure, and multiple sets of assembly structures can improve the tensile strength and torsional stiffness of the two adjacent chain units 10.
[0041] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the cross-section of the assembly groove 101 is circular, the cross-section of the limiting part 102 is also circular, and the limiting part 102 is inserted into the assembly groove 101 to realize the assembly connection of two adjacent chain units 10.
[0042] The above embodiment further defines the cross-sectional shape of both the assembly groove 101 and the limiting part 102 as circular, so that the limiting part 102 does not need to be oriented and aligned during the insertion of the assembly groove 101, reducing the assembly difficulty between the two; in addition, the cylindrical limiting part 102 and the circular assembly groove 101 are assembled and connected, and the circular contact surface 110 can uniformly transmit torque, reduce stress concentration at the connection part, reduce local wear caused by asymmetrical shape, and the above-mentioned assembly connection provides a margin of movement for the relative displacement of two adjacent chain units 10, ensuring the flexibility of movement between the two chain units 10.
[0043] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the length of the limiting part 102 is greater than the depth of the assembly groove 101.
[0044] The above embodiment further limits the length of the limiting part 102 to be greater than the depth of the assembly groove 101. When the limiting part 102 is fully inserted into the assembly groove 101, the limiting part 102 is at least partially exposed in the gap between the two chain units 10. When the connecting rope 20 strings multiple chain units 10 into a chain structure, the limiting part 102 is still partially inserted into the limiting groove of the next chain unit 10, avoiding the problem of misalignment between adjacent chain units 10. Moreover, based on the above design, it can be ensured that the thread end or connection point of the connecting rope 20 is hidden inside the chain unit 10, ensuring the smoothness and aesthetics of the jewelry appearance.
[0045] like Figures 3 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the chain unit 10 is also provided with an inlay groove 104, and the inlay groove 104 is inlaid with a decorative object 30.
[0046] The decorative element 30 can be made of precious metals, gemstones, or pearls. For example, the decorative element 30 can be a diamond. It should be noted that the decorative element 30 can be assembled with the setting groove 104 by means of micro-clamping, rotation locking, adhesive, or magnetic attraction. For example, the decorative element 30 can be assembled with the setting groove 104 by means of micro-clamping. Specifically, the side wall of the setting groove 104 is provided with an elastic cantilever beam, and the bottom of the decorative element 30 is processed with a locking groove. By pressing the decorative element 30 into the assembly groove 101, the cantilever beam deforms and engages with the locking groove, thereby fixing the decorative element 30 to the assembly groove 101.
[0047] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of inlay slots 104 is multiple, and the multiple inlay slots 104 are distributed at intervals.
[0048] The above embodiments further specify the provision of multiple inlay slots 104, each inlay slot 104 can be inlaid with the same or different decorative items 30, which can be customized according to customer needs to meet diverse requirements.
[0049] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the chain unit 10 is formed with a contact surface 110 and a decorative surface 120, the contact surface 110 is planar, and the transition between the contact surface 110 and the decorative surface 120 is a rounded corner design.
[0050] In addition to the features of the above embodiments, this embodiment further specifies that the connecting rope 20 is a high-strength rope.
[0051] The high-strength rope can be made of a flexible linear material. For example, high-strength ropes include, but are not limited to, nylon monofilament fishing line, Kevlar line, polyester braided line, polyester monofilament line, or polyurethane elastic line. In this embodiment, the connecting rope 20 is made of nylon monofilament.
[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
