[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model in this article are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.
[0025] As Figure 1 shown, this nylon waterproof zipper includes a cloth tape 1 and a number of teeth 2. The cloth tape 1 is in a long strip shape, and the above-mentioned teeth 2 are fixedly connected to the outer edge of the cloth tape 1. The number of the teeth 2 is several, and several teeth 2 are evenly distributed along the length direction of the cloth tape 1.
[0026] It further includes a sealing piece 3 and a waterproof layer 4. The above-mentioned sealing piece 3 is in a long strip shape and the middle part of the sealing piece 3 covers several teeth 2. The inner edge of the sealing piece 3 is fixedly connected to the cloth tape 1, and the outer edge of the sealing piece 3 extends out of the teeth 2. The above-mentioned waterproof layer 4 is located outside the cloth tape 1 and the inner edge of the sealing piece 3 is located between the waterproof layer 4 and the cloth tape 1.
[0027] Since the cloth tape 1 is ordinary fabric, it does not have a waterproof effect. The waterproof layer 4 coated on the outside of the cloth tape 1 changes its current situation and enables the cloth tape 1 of the zipper to have a good waterproof effect.
[0028] At the same time, the inner end of the sealing piece 3 is fixedly connected to the cloth tape 1, and the outer end of the sealing piece 3 extends out of the teeth 2. Such a structure stably covers the teeth 2 and the connection between the teeth 2 and the cloth tape 1. Therefore, its waterproof performance is further improved.
[0029] The sealing piece 3 is a flexible plastic sheet.
[0030] The sealing piece 3 made of flexible plastic material can make the sealing piece 3 deform appropriately under the action of external force, which is convenient for the slider to move relative to the teeth 2.
[0031] The inner end of the teeth 2 has a recessed positioning notch 2a, and the outer edge of the cloth tape 1 is embedded in the positioning notch 2a and both sides of the teeth 2 protrude from both sides of the cloth tape 1.
[0032] Such a structure can stably connect the teeth 2 and the cloth tape 1 together.
[0033] The inner edge of the sealing piece 3 has a connecting section 3a protruding towards the cloth tape 1, and the connecting section 3a is located between the cloth tape 1 and the waterproof layer 4.
[0034] Since the connecting section 3a is inclined and bent towards the cloth tape, when the waterproof layer 4 covers the connecting section 3a, the outer side of the waterproof layer 4 can be flush with the outer side of the sealing piece 3, thereby improving the overall structural compactness.
[0035] The connecting section 3a and the sealing piece 3 are of an integral structure.
[0036] The waterproof layer 4 is made of PVC or TPU material.
[0037] The middle part of the inner side of the sealing piece 3 has a protruding contact part 3b, and the contact part 3b contacts the outer side surface of the tooth 2. There is a gap between the outer edge of the sealing piece 3 and the tooth 2.
[0038] After the contact part 3b contacts the surface of the tooth 2, the connection stability between the sealing piece 3 and the tooth 2 can be improved.
[0039] At the same time, the gap between the outer edge of the sealing piece 3 and the tooth 2 can also ensure that the slider can be stably engaged with the tooth 2.
[0040] The number of the sealing pieces 3 is two, and the two sealing pieces 3 are symmetrically arranged on both sides of the cloth tape 1.
[0041] Such a structure has good waterproof effects on both sides of the zipper.
[0042] The inner edges of the two sealing pieces 3 and the cloth tape 1 are connected by stitch sewing.
[0043] The inner side of the sealing piece 3 has a fastening part 3c matching the inner end of the tooth 2, and the contact part 3b and the connecting section 3a are respectively located on both sides of the fastening part 3c.
[0044] The setting of the fastening part 3c can make the sealing piece 3 more stably and tightly cover the cloth tape 1 and the tooth 2.
[0045] The contact part 3b and the connecting section 3a on both sides of the fastening part 3c further improve the structural compactness of the zipper.
[0046] In this nylon waterproof zipper, the teeth are made of nylon material. At the same time, the waterproof layer on the outer side of the cloth tape has a good waterproof effect on the cloth tape. Since the sealing piece blocks the connection between the teeth and the cloth tape, the waterproof effect is further improved.
[0047] At the same time, the inner edge of the sealing piece is located between the waterproof layer and the cloth tape, and the outer side of the sealing piece is flush with the outer side of the waterproof layer, which effectively improves the structural compactness of the entire waterproof zipper.
[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
