[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0018] Refer to Figures 1-4As shown in the figure, an anti-theft zipper includes a zipper tape, a first slider 1, a second slider 2, a first tab 3, and a second tab 4. The first slider 1 and the second slider 2 are oppositely arranged on the zipper tape. The first tab 3 is provided with a first perforation 31 and a first insertion hole 32. The first slider 1 is connected to the first perforation 31. The second tab 4 is provided with a second perforation 41. The second slider 2 is connected to the second perforation 41. An engaging member 5 is provided at the end of the second tab 4. The engaging member 5 is inserted into the first insertion hole 32, and the engaging member 5 is stuck on one side of the first tab 3, so as to be connected and locked with the first tab 3, making the zipper not easily opened, thereby improving its anti-theft performance.
[0019] The first insertion hole 32 includes a square opening 321 and a rectangular opening 322. The rectangular opening 322 is connected to the square opening 321. The rectangular opening 322 is communicated with the first perforation 31. A limiting convex block 3221 is provided at the end of the connecting end of the rectangular opening 322 and the first perforation 31. The limiting convex block 3221 includes two pieces. The two limiting convex blocks 3221 are arranged in a staggered manner, and a passage gap is left between the two limiting convex blocks 3221. The width of the rectangular opening 322 is greater than the thickness of the engaging member 5. Specifically, the width of the rectangular opening 322 is 0.5 mm larger than the thickness of the engaging member 5.
[0020] In one embodiment, referring to Figures 1-3 As shown in the figure, the engaging member 5 is integrally formed with the second tab 4. Specifically, the engaging member 5 includes a connecting portion 51a and a clamping portion 52a. The connecting portion 51a is connected to the second tab 4. The clamping portion 52a is connected to the connecting portion 51a. Among them, the clamping portion 52a is located on one side of the first tab 3 to be stuck on the first tab 3. The clamping portion 52a has an isosceles trapezoidal structure, so as to facilitate the insertion of the clamping portion 52a into the first insertion hole 32. The distance from the limiting convex block 3221 to the side of the square opening 321 is 0.3 mm larger than the long side of the isosceles trapezoidal clamping portion 52a, so that the clamping portion 52a is not easily separated from the first insertion hole 32. More specifically, after the clamping portion 52a passes through the first insertion hole 32, the engaging member 5 rotates 90°, so that the clamping portion 52a is stuck on both sides of the square opening 321, and further the first tab 3 and the second tab 4 are combined and locked, making the zipper not easily opened, achieving the anti-theft effect. At this time, the connecting portion 51a is located in the first insertion hole 32.
