[0021] The embodiments of the present utility model will be described below with reference to the drawings. During this process, to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0022] In addition, the terms used hereinafter are defined based on the functions in the present utility model and may vary according to the intentions or conventions of users and operators. Therefore, these terms are defined based on the entire content of this specification.

[0023] As Figures 1 to 4 shown, a tensile nylon interlocking zipper includes a zipper body 1. The zipper body 1 includes a first zipper tape 11 which is arranged on one edge of the placket of the clothes. A first zipper chain is sewn on the first zipper tape 11. The first zipper chain includes a plurality of first chain teeth 12 which are distributed in a rectangular array. The first chain teeth 12 include a connection and fixing part 121 and a chuck 122. A transition part 125 is arranged between the connection and fixing part 121 and the chuck 122. A wire groove 123 is formed on the surface of the transition part 125 near the connection and fixing part 121. The connecting wire is sewn onto the first zipper tape 11 through the sewing needle of the sewing device, so that the connecting wire is located in the wire groove 123, and then the first chain teeth 12 are sewn on the first zipper tape 11, and the sewing is firm and reliable. Two first cutting grooves 124 are formed on the surface of the transition part 125 near the chuck 122. The first cutting grooves 124 are arc-shaped grooves. The upper and lower ends of the surface of the chuck 122 are both provided with abutting heads 1222 which are arc-shaped. The outer shape of the abutting heads 1222 is adapted to the outer shape of the first cutting grooves 124. A clamping surface 1221 is formed at the connection between the chuck 122 and the first cutting grooves 124. The contact area is increased through surface contact, and thus the tensile strength of the chuck 122 is improved.

[0024] The zipper body 1 further includes a second zipper tape 13 which has the same structure as the first zipper tape 11. The second zipper tape 13 is arranged on the other edge of the placket of the clothes. A second zipper chain is sewn on the second zipper tape 13. The second zipper chain includes a plurality of second chain teeth 14 which are distributed in a rectangular array. The second chain teeth 14 have the same structure as the first chain teeth 12. The chuck 122 of the first chain teeth 12 is clamped between the first cutting grooves of two adjacent second chain teeth 14. At this time, the abutting heads 1222 are clamped in the first cutting grooves 124, and the clamping surfaces 1221 of the first chain teeth 12 are abutted against the two clamping surfaces of the second chain teeth 14, so that the zipper chain will not be easily torn when subjected to a lateral force, and the tensile strength of the zipper body 1 is improved.

[0025] A slider 15 is provided between the first zipper chain and the second zipper chain, facilitating the zipping and unzipping of the two zipper chains. When the zipper body 1 is in the zipped state, the first chain teeth 12 and the two second chain teeth 14 are tightly engaged with each other. The two ends of the locking head 122 of the first chain teeth 12 are respectively engaged with the first cutting grooves of the two second chain teeth 14 through the abutting heads 1222. At this time, the engaging surfaces 1221 of the first chain teeth 12 and the two second chain teeth 14 are abutted against each other, increasing the contact area through surface-to-surface contact. When the zipper body 1 is subjected to a lateral pulling force, the locking heads 122 are abutted against each other through the surfaces, greatly enhancing the strength against the lateral pulling force, so that the zipper body 1 will not be easily pulled open by an external force, with strong safety performance and high tensile performance.

[0026] The specific implementation method is that the first zipper chain and the second zipper chain are zipped together through the slider 15. When the zipper body 1 is in the zipped state, the engaging surfaces 1221 of the first chain teeth 12 and the two second chain teeth 14 are abutted against each other, increasing the contact area through surface-to-surface contact. When the zipper body 1 is subjected to a lateral pulling force, the locking heads 122 are abutted against each other through the surfaces, greatly enhancing the strength against the lateral pulling force, so that the zipper body 1 will not be easily pulled open by an external force. The zipper body 1 can withstand a large lateral pulling force without being damaged, with strong safety performance and high tensile performance.

[0027] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
