[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] like Figure 1As shown, most bracelets and necklaces on the market use cotton or nylon cords as hanging cords, paired with closed clasps with two holes. The disadvantage of this closed clasp is that changing the cord requires damaging or cutting it; if the cord end is knotted or glued, the knot must be removed. Using or changing the cord is particularly inconvenient, cumbersome, and can damage the cord, accessory, or jewelry.

[0026] like Figures 2-8 As shown, this utility model provides a rope buckle structure, including a buckle 1 with a locking opening 2. The locking opening 2 includes a locking channel 21 and an opening 22. The opening 22 is formed on the surface of the buckle 1, and the locking channel 21 is connected to the opening 22. The width of the opening 22 is smaller than the width of the locking channel 21, and the height of the opening 22 is smaller than the height of the locking channel 21. By using a single locking channel opening, and utilizing the bidirectional compression relationship between the hanging ropes 3, as well as the frictional resistance generated between the hanging ropes 3 and between the hanging ropes 3 and the locking channel 21, the length of the hanging rope 3 can be easily adjusted.

[0027] like Figure 2 and Figures 5-7 As shown, the hanging cord 3 passes through the opening 22 and is placed inside the locking channel 21. Generally, there are two or more hanging cords 3. When using or replacing them, there is no need to damage or cut the hanging cords, and the accessories or jewelry will not be damaged. It is easy to assemble but not easy to remove at will, making it simple and reliable.

[0028] The side 4 of the lock track 21 is semi-circular to better allow for maximum contact area with the compressed hanging rope 3. The diameter of the semi-circular arc is 0.05-0.1mm smaller than the diameter of the hanging rope 3, so that after the hanging rope 3 is slightly compressed inside the lock track 21, the two hanging ropes 3 will come together and generate damping. When the two hanging ropes 3 enter the lock track 21, the two side 4 inside the lock track 21 compress the hanging ropes 3. When the hanging ropes 3 are compressed, the contact between adjacent ropes is tighter. At this time, the hanging ropes 3 have three cross-sections of frictional resistance inside the lock track 21, namely the contact surfaces of the two side 4 and the adjacent surfaces of the two hanging ropes 3. Because the hanging ropes 3 are woven from the same material, the frictional damping coefficient is better than that between the hanging ropes 3 and the lock track 21.

[0029] like Figure 2 and Figure 3 As shown, the corners 5 around the opening 22 are chamfered, which can effectively prevent the hanging rope 3 from being blocked when passing through the opening 22, and can better allow the hanging rope 3 to pass through the opening 22 and enter the lock channel 21.

[0030] Without damaging the inner wall of the hanging rope 3 and the opening 22, the width of the opening 22 (the lateral distance of the opening 22 cross section) should be determined by the compression degree of the hanging rope 3. Generally, the hanging rope 3 made of cotton or nylon is woven from three or four strands, or from multiple thin strands forming a hollow weave around the center. The overall compression rate is 70%-80%, and the compression rate of a single strand of a four-strand twisted rope is about 37.5%. Therefore, the width of the opening 22 should be set to 70%-80% of the diameter of the hanging rope 3. If it is less than 37.5%, it will not be able to be installed and inserted into the locking track 21.

[0031] The width of the locking track 21 (the lateral distance of the locking track 21 cross-section) should be the diameter of the hanging rope 3 minus a slight compression ratio of 5%-10% of the hanging rope 3. Since there are two hanging ropes 3, the width of the locking track 21 should be twice the diameter of the hanging rope 3 multiplied by 90-95%, that is, the width of the locking track 21 is 90%-95% of twice the diameter of the hanging rope 3. The fluctuation range of the above values ​​is determined by the tightness of the hanging rope 3 within the locking track 21.

[0032] like Figure 2 and Figure 4 As shown, because the side 4 of the lock track 21 is semi-circular and the diameter of the semi-circular arc is 0.05-0.1mm smaller than the diameter of the hanging rope 3, the height of the lock track 21 (the longitudinal distance of the lock track 21 cross section) is 0.05-0.1mm smaller than the diameter of the hanging rope 3.

[0033] like Figure 2 and Figure 7 As shown, taking a standard 2.0mm diameter four-strand nylon cord as an example, the locking damping is set to be slightly loose, and the insertion setting is slightly tight. At this time, the width of the opening 22 is 2 x 70% = 1.4mm, the height of the locking channel 21 is 2 - 0.05 = 1.95mm, and the width of the locking channel 21 is 2 x 2.0 x 95% = 3.8mm. In this way, the cord 3 can be easily inserted into the locking channel 21 like a magazine in a bullet without disassembling the cord end knot or buckle, and it will not slip out during use. If it is necessary to remove the cord 3, a force perpendicular to the locking channel 21 can be applied to remove the cord 3 sequentially. The cord 3 of accessories or jewelry can be easily removed without disassembling the cord end. Furthermore, during normal use, the cord 3 will not loosen or fall out of the buckle structure.

[0034] In summary, this cord buckle structure works similarly to a bullet being inserted into a magazine. First, one cord 3 is passed through the opening 22 and inserted into one side of the locking channel 21. Then, using the compression of the cord 3, another cord 3 (the other end of the first cord) is inserted into the other side of the locking channel 21. After the two cords 3 release their compression within the locking channel 21, they naturally adhere to the inner wall of the locking channel 21, generating frictional damping between themselves and the cords 3, thus securing the cords 3 firmly within the locking channel 21. Simultaneously, the length of the inserted cords 3 can be adjusted (e.g., the circumference of the accessory cord, the diameter of the bracelet, the diameter of the necklace, etc.). Because the area of ​​the cord 3 released between the side 4 of the locking channel 21 and the adjacent cords 3 is larger than that of the opening 22, and because the locking channel 21 is smoother, the cord 3 will not shift out of position without applying a precise pulling force perpendicular to the locking channel 21 and the opening 22. Furthermore, during the use of the accessory, both the locking channel 21 and the opening 22 are perpendicular to the human skin, and there is no condition to apply any corresponding pulling force. The hanging cord 3 will not detach from the locking channel 21 and will be tightly locked onto the buckle 1. Therefore, the cord buckle structure of this application is simple, easy to use, safe, and reliable, and will not damage the hanging cord 3 or the accessory during use or disassembly.
