[0026] In addition, the following terms are defined based on the functions of the present invention and may vary depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire content of this specification.

[0027] like Figures 1 to 8As shown, a glue-filled zipper includes a zipper tape 1 and a chain group 2, wherein the zipper tape 1 is provided with two, and the chain group 2 is provided with two. The two chain groups 2 are sewn on the two zipper tapes 1 respectively, and a slider 4 is provided between the two chain groups 2 to facilitate the closing and opening of the two chain groups 2. The chain group 2 includes a plurality of chain teeth 21, and the plurality of chain teeth 21 are distributed in a rectangular array. The chain teeth 21 include a fixing portion 211 and a clamping head 212. A transition portion 213 is provided between the fixing portion 211 and the clamping head 212. Two arc grooves 214 are provided on the surface of the transition portion 213 near the clamping head 212. A cutting groove 2121 is provided in the middle of the side wall of the clamping head 212. A contact head 2122 is provided at both upper and lower ends of the surface of the clamping head 212, and the contact head 2122 is arc-shaped. The shape of the contact head 2122 is adapted to the shape of the arc groove 214, and a locking surface 2123 is formed at the connection between the clamping head 212 and the arc groove 214. A connecting rope 22 is provided at a position opposite to the fixed portion 211 of the plurality of chain teeth 21, and the connecting rope 22 connects the evenly distributed chain teeth 21 together. A reinforcing rib 23 is provided at a position opposite to the transition portion 213 of the plurality of chain teeth 21, and the reinforcing rib 23 connects the evenly distributed chain teeth 21 together, further strengthening the entire chain group 2, so that the chain group 2 will not be easily torn when subjected to lateral force, thereby improving the tensile strength of the zipper.

[0028] like Figures 3 to 5 As shown, a waterproof membrane 3 is provided in the middle of the side wall of the reinforcing rib 23, and the waterproof membrane 3 is located between the two chain teeth 21. The end of the waterproof membrane 3 away from the reinforcing rib 23 is plugged into the groove 2121. When the zipper is in the closed state, one end of the waterproof membrane 3 goes deep into the groove 2121 to seal the space surrounded by the three chain teeth 21, preventing external cold air and liquid from entering the interior of the zipper, thereby playing a role in heat preservation and waterproofing. At this time, the three chain teeth 21 are clamped with each other, and the middle chain tooth 2 The two ends of the clamping head 212 of 1 are respectively engaged with the arc groove 214 of the chain teeth 21 on both sides through the abutting head 2122. At this time, the engaging surfaces 2123 of the three chain teeth 21 abut against each other, and the contact area is increased through surface-to-surface contact. When the zipper is subjected to lateral tension, the clamping heads 212 abut against each other through the surfaces, which greatly enhances the strength against lateral tension, so that the zipper will not be easily pulled open by external force, reduces the displacement of the zipper chain seam, and effectively prevents the waterproof membrane 3 from being separated from the cutting groove 2121, with strong safety performance and high quality.

[0029] like Figures 6 to 8As shown, the two zipper tapes 1 are respectively provided with a first glue-filled nylon cloth 5 and a second glue-filled nylon cloth 6, the first glue-filled nylon cloth 5 is located on the chain group 2, and a placement groove 51 is opened on the side wall of the first glue-filled nylon cloth 5, and a plurality of buckles 7 are arranged in an array in the placement groove 51, and a convex strip 61 is provided on the side wall of the second glue-filled nylon cloth 6, and the shape of the convex strip 61 is adapted to the shape of the placement groove 51, and a plurality of card caps 8 are arranged in an array on the side wall of the convex strip 61, and the plurality of card caps 8 correspond to the plurality of buckles 7 one-to-one. When the zipper is in the closed state, the convex strip 61 is inserted into the placement groove 51, and the card cap 8 is engaged with the buckle 7. When the zipper is subjected to lateral tension, the card cap 8 and the buckle 7 cooperate to further reduce the enlargement of the gap between the first glue-filled nylon cloth 5 and the second glue-filled nylon cloth 6, thereby reducing the entry of cold air and liquid into the interior of the zipper.

[0030] The specific implementation method is that a connecting rope 22 is provided in the zipper strip to connect multiple chain teeth 21 together, and a reinforcing rib 23 is provided on the front of the transition part 213 of the multiple chain teeth 21, so that the strength of the entire zipper is greatly enhanced. When the zipper is in the closed state, the engaging surfaces 2123 of the chain teeth 21 abut against each other, and the contact area is increased through surface-to-surface contact. When the zipper is subjected to lateral tension, the clamping heads 212 abut against each other through the surfaces, which greatly enhances the strength of resisting lateral tension, so that the zipper will not be easily pulled open by external force, has strong safety performance and high quality, and the zipper can withstand large lateral tension without Damaged, at this time, one end of the waterproof membrane 3 penetrates into the groove 2121 to seal the space surrounded by the three chain teeth 21, preventing external cold air and liquid from entering the inside of the zipper, thereby playing a role in heat preservation and waterproofing, and the convex strip 61 is inserted into the placement groove 51, and the card cap 8 is engaged with the buckle 7. The card cap 8 and the buckle 7 cooperate to further reduce the enlargement of the gap between the first glue-filled nylon cloth 5 and the second glue-filled nylon cloth 6, reducing the entry of cold air and liquid into the interior of the zipper. Through double protection, on the one hand, the expansion of the gap in the middle of the zipper is reduced, and on the other hand, the entry of cold air and liquid into the interior of the zipper is reduced, thereby improving the protection ability of the zipper.
