DETAILED DESCRIPTION

[0024] The following detailed description of the technical solutions of the present disclosure is provided with reference to specific embodiments. However, it should be appreciated that this does not constitute any limitation on the present disclosure.

[0025] As shown in FIGS. 1-7, a building block string accessory according to embodiments of the present disclosure includes a building block 1 and a string 3. A first side of the building block 1 is provided with a pair of mirror-symmetrical stringing structures 13 that are spaced apart, each stringing structure 13 having a stringing through-hole 131. The string 3 includes two threading sections 31 and two connecting sections 32, which are alternately arranged and interconnected to form a closed-loop structure. The threading sections 31 are aligned with the stringing structures 13 and are threaded through the stringing through-holes 131 of the corresponding stringing structures 13. In some embodiments, a connecting member is provided between the two connecting sections 32, and the connecting member is detachably connected to the two connecting sections 32.

[0026] Referring to FIGS. 1-3, when assembling the string 3 with several building blocks 1, the building blocks 1 are arranged such that the stringing through-holes 131 of adjacent building blocks 1 are aligned one-to-one. The string 3 first passes through the stringing structures 13 on the same side (i.e., a first side) of several building blocks 1, threading from the first side of the first building block 1 to the first side of the last building block 1. The section of the string 3 that passes through the first side of the building blocks 1 is referred to as a first threading section 31. After the string 3 exits from the last building block 1, it loops to the opposite side of the last building block 1, forming a first connecting section 32. The string 3 then passes through the stringing structures 13 on the opposite side (i.e., a second side) of several building blocks 1, threading from the second side of the last building block 1 to the second side of the first building block 1. The section of the string 3 that passes through the second side of the building blocks 1 is referred to as a second threading section 31. After the string 3 exits from the first building block 1, the two ends of the string 3 are connected end to end, forming a circular closed loop, and creating a second connecting section 32 located on one side of the first building block 1. In this manner, the string 3 and the building blocks 1 together form a chain with the building blocks 1 threaded onto it. The first connecting section 32 and the second connecting section 32 serve as the two ends of the chain. The first and second connecting sections 32 are then connected to each other by the connecting member, linking the ends of the chain and ultimately forming a closed loop, thus assembling the string accessory.

[0027] During the assembly process, the string 3 only needs to be sequentially threaded through both sides of each building block 1, after which the two ends of the string 3 are connected using methods such as knotting, gluing, or thermal sealing. The entire process can be performed with both hands, and precise alignment of the string and holes is not required. The string 3 can be twisted and adjusted as needed during the threading process, effectively reducing the assembly difficulty of threading multiple building blocks 1 onto the string 3 and improving production efficiency.

[0028] In one or more embodiments, during actual use, the string accessory can function as a bracelet, a necklace, or other annular ornaments.

[0029] In one or more embodiments, as shown in FIG. 4, the building block 1 and the stringing structure 13 are integrally formed. In some examples, the building block 1 and the stringing structure 13 may be connected using methods such as gluing or thermal fusion.

[0030] In some embodiments, as shown in FIG. 2, the connecting member is a first connecting block 2. The outer surface of the first connecting block 2 is provided with a circumferential groove 23, and both the connecting sections 32 are sleeved onto the groove 23 of the first connecting block 2.

[0031] In some embodiments, as shown in FIGS. 2 and 3, the first connecting block 2 includes a first clamping cover 22 and a second clamping cover 21. The middle portion of the first clamping cover 22 is fixedly connected to a first connecting post 221, which is provided with a first socket 222 that opens toward the second clamping cover 21. The middle portion of the second clamping cover 21 is fixedly connected to a second connecting post 212, which is detachably inserted into the first socket 222. A receiving space is formed between the second clamping cover 21 and the first clamping cover 22, and the receiving space is arranged around the first connecting post 221 to create the groove 23 on the first connecting block 2.

[0032] In some examples, the first socket 222 is a polygonal hole, and correspondingly, the second connecting post 212 is a polygonal prism that matches the polygonal hole. This design prevents relative rotation between the first clamping cover 22 and the second clamping cover 21.

[0033] In one or more embodiments, the second connecting post 212 is provided with a second socket 213 that opens toward the first connecting post 221, and a positioning post 223 is arranged along the central axis of the second socket 213. One end of the positioning post 223 is fixedly connected to the first clamping cover 22, while its opposite end is detachably inserted into the second socket 213. This arrangement enhances the installation precision between the first clamping cover 22 and the second clamping cover 21.

[0034] In one or more embodiments, the second clamping cover 21 is provided with an annular positioning groove 211, which is located on the outer side of the second connecting post 212. The first connecting post 221 is detachably inserted into the positioning groove 211.

[0035] In some embodiments, as shown in FIGS. 6 and 7, the connecting member is a second connecting block 4. Both sides of the second connecting block 4 are fixedly connected to connecting hooks 41 corresponding to the connecting sections 32, and the connecting sections 32 is sleeved onto the inner sides of the corresponding connecting hooks 41.

[0036] In some embodiments, an opening of the connecting hook 41 may be oriented either to the outside or to the inside of the assembled string accessory.

[0037] In some examples, the connecting member is a tying rope, which is detachably tied to the connecting sections 32 on both sides.

[0038] In some examples, the connecting member is a paperclip, and the connecting sections 32 on both sides are threaded through the paperclip.

[0039] According to one or more embodiments, as shown in FIG. 4, one side of the stringing structure 13 is provided with an opening 132 that is parallel to its central axis. The opening 132 is in communication with the stringing through-hole 131. The stringing structure 13 forms a hook-shaped structure through the opening 132, wherein a handle end of the stringing structure 13 is fixedly connected to the first side of the building block 1, and a hook tip of the stringing structure 13 is directed toward the first side of the building block 1.

[0040] In addition to a straight tubular structure, the stringing structure 13 may also adopt a hook-shaped structure. For example, the opening 132, parallel to the central axis, is cut at the position of the central axis of the stringing structure 13. The opening 132 interrupts the continuous connection between the stringing structure 13 and the first side of the building block 1, thus forming a hook-shaped structure. The arrangement of the opening 132 allows the string 3 to be threaded through the stringing structure 13 in a more flexible and convenient manner. The string 3 can either pass through the stringing through-hole 131 or be inserted and removed from the opening 132, making the assembly process more adaptable and improving assembly efficiency.

[0041] In some examples, as shown in FIG. 1, the two threading sections 31 and the two connecting sections 32 of the string 3 are integrally formed.

[0042] According to one or more embodiments, when the stringing structure 13 adopts the hook-shaped structure, the string 3 can be selected either as an integrally formed loop or by first connecting its ends end-to-end to form a ring structure. The ring structure is then inserted into the stringing through-hole 131 through the opening 132 of the stringing structure 13. This design provides versatility in accessory selection, allowing manufacturers to choose appropriate accessories or assembly processes with different sequences based on market demand. This approach helps reduce production costs, increase market share, and enhance production efficiency.

[0043] According to one or more embodiments, as shown in FIG. 4, the first side of the building block 1 is provided with a protruding portion 16 located between the two stringing structures 13. A predefined gap 14 is formed between the protruding portion 16 and the hook tips of the stringing structures 13 on both sides for preventing the threading section 31 from disengaging.

[0044] In some practical examples, the opening 132 on the stringing structure 13 is aligned with a side of the protruding portion 16. The side of the protruding portion 16 prevents the string 3 from disengaging from the stringing structure 13 at the opening 132. During the wearing process of the string accessory, the string 3 naturally shifts or moves toward the opening 132. When the string 3 attempts to exit from the opening 132, it will contact against the side of the protruding portion 16. Without external force, the string 3 is unlikely to disengage from the stringing structure 13 through its own movement. To remove the string 3 from the opening 132, it is necessary to manually pull the string 3 into the predefined gap 14 and then withdraw the string 3 within the gap 14.

[0045] According to one or more embodiments, as shown in FIGS. 4 and 8, a second side of the building block 1 is provided with a protrusion 12 for mounting a decorative piece 5. The second side of the building block 1 and the first side of the building block 1 are opposite sides of the building block 1.

[0046] In some practical examples, the building block 1 can be inserted into a mounting hole of the decorative piece 5 through the protrusion 12, so that the decorative piece 5 is fixed to the building block 1. This allows the building block 1 to externally connect to various decorative pieces 5 via the protrusion 12, creating diverse assembly effects and enhancing product appeal.

[0047] In some examples, the protrusion 12 may be a solid structure or may adopt hollow or perforated designs. In certain instances, the protrusion features a perforated structure, where a blind hole is formed on the side of the protrusion facing away from the building block. The blind hole not only reduces the overall weight but also allows the decorative piece 5 to be inserted into the blind hole for secure attachment.

[0048] In some embodiments, as shown in FIGS. 4 and 8, at least two protrusions 12 are provided and adjacent protrusions 12 are spaced apart from each other, allowing a single building block 1 to externally connect to two decorative pieces 5 or to connect one large decorative piece 5 with two or more protrusions 12.

[0049] In some embodiments, as shown in FIGS. 4 and 8, a recess 11 is formed on the second side of the building block 1, and the protrusion 12 is positioned within the recess 11. The recess 11 serves as a limiting structure for the decorative piece 5 mounted on the protrusion 12, preventing the decorative piece 5 from directly falling off under external impact. In some examples, when selecting a mixed combination of building blocks 1 with and without recesses 11, the recesses 11 on the building blocks 1 allow the string accessory to present a staggered layering effect of different decorative pieces 5. This also prevents the decorative pieces 5 from being positioned on the same curved surface, thereby avoiding assembly interference.

[0050] In some embodiments, as shown in FIG. 4, the recess 11 and the protruding portion 16 may be configured either independently or in combination. For example, the recess 11 and the protruding portion 16 are integrally formed into a bent structure. The center of the second side of the building block 1 is recessed to a certain depth, while the area on the opposite side corresponding to the recess protrudes by a corresponding height. This ultimately forms a bent structure in the center of the building block 1, with one side recessed and the opposite side protruding.

[0051] In some embodiments, as shown in FIG. 4, edges of the building block 1 are provided with notches 15. The notches 15 are located on two side surfaces in the width direction of the building block 1 and are positioned at the center. The threading structures 13 are arranged on opposite two sides in the length direction of the building block 1.

[0052] In some embodiments, as shown in FIG. 5, the two side surfaces of the building block 1 in the width direction are inclined planes arranged as mirror images of each other. The distance between the two inclined planes gradually decreases from the first side to the threading structure 13.

[0053] It should be noted that various embodiments of the present disclosure allow for modifications and refinements to be made by those skilled in the art without departing from the principles of the disclosure. Such modifications and refinements should also be regarded as falling within the scope of the present disclosure.
