[0003] Chinese utility model patent CN217284960U provides a double-layer telescopic zipper, in which the sides of the first cloth tape and the third cloth tape away from the second chain tooth are respectively covered with a protective layer, and the protective layer is a chain adhesive or a protective cloth with a surface covered with a chain adhesive. This structure is connected to the zipper by gluing, and is essentially an additional structure on the zipper. This solution directly improves the zipper cloth tape and designs a zipper that does not affect the aesthetics even if it is crooked. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a telescopic zipper with a Y-shaped cloth tape, which solves the problem that the existing zipper affects the aesthetics after the seam line is crooked.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a Y-shaped cloth tape retractable zipper, including a main body, the main body includes a first cloth tape, a second cloth tape and a third cloth tape, a first zipper structure and a second zipper structure are respectively arranged between the first cloth tape, the third cloth tape and the second cloth tape, a Y-shaped cloth tape structure is respectively arranged on the side of the first cloth tape and the third cloth tape away from the second cloth tape, the Y-shaped cloth tape structure includes an upper cloth tape and a lower cloth tape, and a stitching gap is arranged in the middle of the upper cloth tape and the lower cloth tape.

[0006] By adopting the above technical solution, the upper cloth tape is folded toward the direction close to the second cloth tape, and the needle of the sewing equipment passes through the lower cloth tape to sew the zipper and the box shell to fix it. After the sewing is completed, the upper cloth tape returns to its position to cover the sewing line. Even if the machine is crooked, it will not affect the appearance of the product. The gap between the stitches is reserved for the sewing line. After the sewing is completed, the upper cloth tape still remains flush with the first cloth tape or the third cloth tape to avoid bulging or eversion, and the product has a good appearance.

[0007] Furthermore, the Y-shaped cloth belt structure opens toward the outside of the main body.

[0008] By adopting the above technical solution, the upper cloth belt is prevented from folding and affecting the operator's vision.

[0009] Furthermore, the length of the upper fabric tape is greater than the length of the lower fabric tape.

[0010] By adopting the above technical solution, the upper cloth belt can completely cover the lower cloth belt, and in appearance, it is no different from an ordinary cloth belt.

[0011] Furthermore, at least one of the first zipper structure and the second zipper structure is a telescopic zipper structure.

[0012] By adopting the above technical solution, a zipper with variable width is formed to expand or contract the space of the suitcase.

[0013] Furthermore, the telescopic zipper structure includes a fourth cloth tape, a first tooth chain and a second tooth chain.

[0014] Furthermore, the first toothed chain is arranged on the first cloth tape, the second toothed chain is arranged on the second cloth tape, the fourth cloth tape connects the first cloth tape and the second cloth tape and covers the first toothed chain and the second toothed chain, and the first toothed chain and the second toothed chain are connected by a zipper head.

[0015] By adopting the above technical solution, the expansion and contraction of the zipper width can be achieved.

[0016] Furthermore, the Y-shaped fabric tape structure is made of TPU material, and the first fabric tape and the third fabric tape are respectively integrated with the Y-shaped fabric tape structure.

[0017] By adopting the technical solution, production is facilitated.

[0018] Compared with the prior art, the advantages of the utility model are: 1. The Y-shaped cloth tape structure is adopted to hide the stitching line without affecting the operator's sewing operation, thereby reducing the difficulty of operation and improving the aesthetics of the product; 2. The Y-shaped cloth tape structure is reasonably designed. The cloth tape, as a part of the zipper, has good integrity and does not have the problem of falling off or the problem of secondary operation of the zipper after sewing; 3. The telescopic zipper structure effectively expands the width of the cloth tape, which is suitable for the needs of suitcases of different specifications and has a wide range of applications.
