Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of jewelry, in particular to a chain structure. BACKGROUND

[0002] The existing chain structure is divided into machine-compiled chain, hand-made chain and 3D-printed chain, wherein: the machine-compiled chain structure is mostly mass-produced by machines, and the appearance shape of the chain structure cannot be easily changed; the hand-made chain is limited by the precision of handwork, and the size is generally large and has no feasibility of mass production; the 3D-printed chain is directly printed by 3D printing technology, and the appearance shape of the chain structure can be changed by 3D modeling, so that the design becomes very flexible. The invention patent with publication number CN106235540A discloses a movable connection assembly connected by a plurality of connection units, wherein the connection unit comprises a top part, a bottom part and at least one pair of spiral columns connecting the top part and the bottom part, each pair of spiral columns is arranged in central symmetry around the center of the bottom part, and the middle end of each spiral column in each pair of spiral columns extends out of the outer edge of the top part and the outer edge of the bottom part, the movable connection assembly is formed by mutually clamping one spiral column on one connection unit and one spiral column on another connection unit, and there is a predetermined movable gap between the spiral columns of each two connected connection units in the movable connection assembly. In the above movable connection assembly, two spiral columns of different connection units are clamped to link, which can realize the linkage of different connection units, but when the formed chain structure is single-row, the problem of unstable gravity center exists, that is: when the chain is lifted, the chain will be twisted greatly. In addition, in some other chain structures, due to the design of the linkage structure between different accessory units not meeting the layering requirements of 3D printing, the 3D printing technology cannot be used for production and manufacturing. SUMMARY

[0003] The purpose of the present application is to provide a chain structure which adopts X-shaped structure and C-shaped structure to link adjacent accessory units, so that the formed chain structure has strong activity, soft shape, is not easy to twist in the vertical hanging situation, and has better user experience.

[0004] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0005] A chain structure comprises a plurality of mutually linked accessory units, each of which comprises a top part, a bottom part, and a first linking part and a second linking part connected between the top part and the bottom part, the first linking part being in an X-shaped structure, with both ends of one side connected to the top part and both ends of the other side connected to the bottom part, and the second linking part being in a C-shaped structure, when two adjacent accessory units are linked, the second linking part in one accessory unit penetrates from the gap between the first linking part and the top part in the other accessory unit and penetrates out of the gap between the first linking part and the bottom part in the other accessory unit, and the first linking part and the second linking part are not in contact.

[0006] Further, the top part and the bottom part in each accessory unit are provided with openings on the side edges corresponding to the side on which the accessory unit is linked to the adjacent accessory unit through the first linking part, to reserve space to avoid the second linking part in the adjacent accessory unit.

[0007] Further, the openings provided on the side edges of the top part are located at the lower edge thereof, and the openings provided on the side edges of the bottom part are located at the upper edge thereof.

[0008] Further, the first linking part is convex outward away from the center of the accessory unit in which it is located, and the second linking part is convex outward away from the center of the accessory unit in which it is located.

[0009] Further, in each accessory unit, the first linking part and the second linking part are integrally formed with the top part and the bottom part.

[0010] Further, the top part and the bottom part are both in a square block structure.

[0011] Further, the top part and the bottom part are both in a regular hexagonal block structure.

[0012] The present application has the following advantages:

[0013] Compared with the prior art, the chain structure of the present application uses the first linking part in an X-shaped structure and the second linking part in a C-shaped structure to link two adjacent accessory units, on the one hand, the chain structure formed thereby is flexible and has a soft form, but is not prone to twisting in a hanging situation, providing a better user experience, and on the other hand, based on the structural design of the chain, 3D printing technology can be directly used for processing and manufacturing.

[0020] The present application will be further described below in conjunction with the accompanying drawings.

[0021] Please refer to Figures 1-5 the drawing, a chain structure includes a plurality of accessory units 1 linked with each other.

[0022] The accessory unit 1 includes a top part 2, a bottom part 3, and a first linking part 4 and a second linking part 5 connected between the top part 2 and the bottom part 3, the first linking part 4 is an X-shaped structure, and both ends of one side thereof are connected with the top part 2, and both ends of the other side thereof are connected with the bottom part 3, the second linking part 5 is a C-shaped structure (or an arc-shaped structure).

[0023] Among them, the connection positions of the first linking part 4 and the second linking part 5 with the top part 2 are close to the edges of the top part 2, the connection positions of the first linking part 4 and the second linking part 5 with the bottom part 3 are close to the edges of the bottom part 3, and the specific connection positions are determined according to the actual situation.

[0024] As shown in Figure 3 the drawing, as one of the embodiments, the top part 2 and the bottom part 3 are both square block structures.

[0025] As shown in Figure 1 the drawing, as another embodiment, the top part 2 and the bottom part 3 are both regular hexagonal block structures.

[0026] When the adjacent accessory units 1 are linked, the second linking part 5 in one accessory unit 1 penetrates from the gap between the first linking part 4 and the top part 2 of the other accessory unit 1, and penetrates out from the gap between the first linking part 4 and the bottom part 3 of the other accessory unit 1, and the first linking part 4 and the second linking part 5 are not in contact.

[0027] The first linking part 4 is convex to the direction away from the center of the accessory unit 1, and the second linking part 5 is convex to the direction away from the center of the accessory unit 1, which facilitates the mutual linking of the first linking part 4 and the second linking part 5.

[0028] According to the above design, the chain structure can be directly manufactured by using the 3D printing technology.

[0029] If the 3D printing technology is used for manufacturing, the first linking part 4 and the second linking part 5 are integrally formed with the top part 2 and the bottom part 3 in each accessory unit 1.

[0030] In the above technical solution, the top part 2 and the bottom part 3 in each accessory unit 1 are provided with openings 6 on the side edges corresponding to the side of the accessory unit 1 linked with the adjacent accessory unit 1 by the first linking part 4, which are used for reserving space to avoid the second linking part 5 in the adjacent accessory unit 1.
