[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] like Figures 1 to 4 As shown, this utility model provides a locking zipper 100, which includes an outer zipper portion 10 and an inner zipper portion 20. The inner surface of the outer zipper portion 10 is snapped onto the outer surface of the inner zipper portion 20. The outer zipper portion 10 also has a handle portion 30, which is designed to facilitate the opening and closing of the inner zipper portion 20 and the outer zipper portion 10. In this embodiment, the locking zipper 100 is made of plastic.

[0030] The outer zipper portion 10 includes a lower mounting portion 11 and a buckle portion 12. The buckle portion 12 is disposed on the upper inner side of the lower mounting portion 11, and the handle portion 30 is disposed at the top center of the buckle portion 12. The buckle portion 12 is provided with a slot 121. Preferably, there are two or more slots 121. In this embodiment, three vertically spaced limiting strips 122 are provided on the inner surface of the buckle portion 12. The free ends of the two upper limiting strips 122 are provided with limiting portions 123 extending downward and inward. More specifically, the limiting strips 122 are gradually thinner towards the limiting portions 123. The top surface of the limiting strips 122 gradually slopes downward towards the limiting portions 123 to facilitate buckle installation.

[0031] The inner zipper portion 20 includes an upper mounting portion 21 and a locking portion 22, with the locking portion 22 located on the lower outer side of the upper mounting portion 21. At least two vertically arranged locking strips 221 are provided on the outer surface of the locking portion 22, extending along the extension direction of the inner zipper strip 20. A hook portion 222 extending upward and inward is provided on the free outer end of each locking strip 221. Furthermore, in this embodiment, the upper mounting portion 21 extends horizontally, and the back of the locking portion 22 protrudes inward, ensuring that the upper mounting portion 21 remains substantially flat with the lower mounting portion 11 after installation. Additionally, the inner surface of the handle portion 30 is provided with anti-slip texture 31, and the outer surfaces of the upper mounting portion 21 and the lower mounting portion 11 are provided with raised and recessed stripes 32.

[0032] During installation, the engaging part 22 and the buckle part 12 are pressed together internally and externally. The two locking strips 221 of the engaging part 22 are embedded in the corresponding slots 121 of the buckle part 12, and the hook part 222 of the engaging part 22 and the limiting part 122 of the buckle part 12 are locked together internally and externally, resulting in a tight installation and good sealing. When it needs to be opened, it can be opened by rotating it outward with the handle 30. During the rotation, the limiting part 122 of the buckle part 12 will disengage from the hook part, so that the bag opening can be easily opened.

[0033] like Figures 5 to 7 As shown, this is a bag opening structure provided by this utility model. This bag opening structure can be used on the opening of cooling clothing, and can be used by people, pets, etc. Of course, it is not limited to cooling clothing, but can also be used on other bag structures that require waterproofing or high sealing performance. Its specific application is not limited here.

[0034] The bag opening structure includes an outer layer 40, a snap zipper 100, and a welded layer 50, which are arranged sequentially from the inside to the outside. Furthermore, an inner layer 60 is provided on the inner side, and the inner layer 60 and the outer layer 40 enclose a cavity 70. The welded layer 50 secures the snap zipper to the outer layer 40.

[0035] The outer layer 40 is provided with a bag opening 41, and the bag opening 41 is provided with a plurality of through holes 42 around its perimeter. Specifically, the bag opening 41 is provided with at least two rows of through holes 42 around its perimeter, and the inner and outer through holes 42 are staggered. The overall size of the buckle zipper 100 is larger than the bag opening 41, and the through holes 42 of the bag opening 11 are provided corresponding to the upper mounting part 21 and the lower mounting part 11, while the buckle part 12, the engaging part 22 and the handle part 30 of the middle part are all exposed from the inside to the outside of the bag opening 41.

[0036] The welding layer 50 is made of thermoplastic material, and its inner surface is welded to the corresponding outer surface of the latch zipper 100 through the through hole 42. In this embodiment, the welding layer 50 can be welded to the latch zipper 100 by means of an ultrasonic welding machine, a hot press welding machine, or the like. Furthermore, the outer surfaces of the upper mounting portion 21 and the lower mounting portion 11 of the latch zipper 100 are provided with concave and convex stripes 32 extending along their extension direction. The stripes 32 not only serve as anti-slip, preventing displacement during lamination and pressing, but also increase the welding contact area.

[0037] In summary, the snap-lock zipper of this utility model uses an internal and external snap-fit ​​method for sealing and includes a handle for opening the zipper. The overall structure is simple and easy to operate. After the snap-lock part 12 and the engaging part 22 are engaged, the hook part 222 and the limiting part 122 are interlocked and limited internally and externally, resulting in a tight installation and good sealing. Furthermore, compared to traditional zipper pull structures, the snap-lock zipper of this utility model has lower production costs and higher production efficiency. Additionally, the snap-lock zipper can be fixed by welding through a welded layer, making operation simple and installation stable. This utility model is highly practical and has significant potential for widespread application.

[0038] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
