DETAILED DESCRIPTION OF THE INVENTION

[0029] The following describes the specific implementation manners of the embodiments of the present utility model with reference to the accompanying drawings.

[0030] Refer to Figures 1 to 3 , a wear-resistant and high-strength invisible zipper, including a pair of tapes 10, a pair of teeth 20, a set of top stops 30, a square fixing pin 40 and an invisible slider 50. The top stops 30 and the square fixing pin 40 are respectively arranged at the upper and lower ends of the tape 10. The pair of tapes 10 are two long strip-shaped tapes. The tape 10 is bent in the width direction to form a U-shaped structure with one long side and one short side. The long side is the fabric joint 11, and the short side is the tooth joint 12. The teeth 20 are respectively stitched to the tooth joint 12 of the tape 10 through the sewing thread 70.

[0031] Specifically, refer to Figure 3, the sewing thread 70 is preferably a high-strength sewing thread 70. One side of the teeth 20 is attached to the tooth joint portion 12. A groove portion 21 for winding the sewing thread 70 is provided on the other side of the teeth 20. A tooth center line 22 for sewing is provided inside the teeth 20. During sewing, the sewing thread 70 winds and sinks into the groove portion 21, and sews the teeth 20, the tooth center line 22, and the tooth joint portion 12 together.

[0032] Referring to Figure 4 and Figure 5 , the invisible slider 50 includes a slider body and a pull tab 59. The slider body is a concave-shaped slider body composed of a lower boat plate 51, side walls, and an upper boat plate. A cushion rib for raising and suspending the teeth 20 of the zipper is provided on the inner side wall of the concave-shaped slider body. An upper rib 57 for horizontally separating the left and right teeth 20 is provided inside the slider body.

[0033] Specifically, referring to Figures 4 to 6 , the side walls include a left side wall 52 and a right side wall 53. The upper boat plate includes a left upper boat plate 54 and a right upper boat plate 55. The left and right sides in the width direction of the lower boat plate 51 respectively extend upward to form the above-mentioned left side wall 52 and right side wall 53. The ends of the left side wall 52 and the right side wall 53 respectively extend inward to form the above-mentioned left upper boat plate 54 and right upper boat plate 55. A cloth seam spacing 56 for the zipper tape 10 to be rolled in is formed at an interval between the left upper boat plate 54 and the right upper boat plate 55. In this embodiment, the lower boat plate 51, the left side wall 52, the right side wall 53, the left upper boat plate 54, and the right upper boat plate 55 are preferably integrally formed. The upper rib 57 is vertically provided on the lower boat plate 51 and extends outside the slider body. A pull nose 58 is riveted to the extending end of the upper rib 57. The pull tab 59 is connected to the pull nose 58.

[0034] Referring to Figure 5 and Figure 6 , the invisible zipper is assembled and zipped on the teeth 20 of the zipper tape 10. Among them, the tooth joint portion 12 and the teeth 20 after the zipper tape 10 is bent are received in the inner cavity of the concave-shaped slider body. However, since the zipper tape 10 is a fiber fabric and has a certain elasticity, in actual production, it will affect the consistency of the short side length after the tape is bent, that is, there will be differences in the short side parts of the two zipper tapes 10 after being bent. If the tooth joint portion 12 is slightly wider than the teeth 20, the edge of the tooth joint portion 12 will contact the side wall of the slider body, thereby increasing the friction when the zipper is zipped and affecting the smoothness of zipping. For this reason, the present utility model also provides a relief groove 61 for avoiding the zipper tape 10 inside the slider body. The relief groove 61 includes a left relief groove 61 and a right relief groove 61. The left relief groove 61 and the right relief groove 61 are respectively provided on the left side wall 52 and the right side wall 53.

[0035] In addition, referring to Figure 5 and Figure 6In order to further enhance the smoothness of the zipper when closing and closing, the utility model is provided with side guide ribs on the side wall for guiding the movement trajectory of the chain element 20. The side guide ribs include a left guide rib 62 and a right guide rib 63. The left guide rib 62 and the right guide rib 63 are respectively arranged at the inner middle part of the left wall 52 and the right wall 53, thereby ensuring the smoothness of the zipper closing and closing movement and the accuracy of the running position, and preventing the closing and closing from being stuck. Preferably, in order to further improve the matching stability and smoothness between the left guide rib 62 and the right guide rib 63 and the chain element 20, the side of the left guide rib 62 and the right guide rib 63 facing the chain element 20 in this embodiment is provided with an inclined surface matching the curved outer surface of the chain element 20.

[0036] Reference Figure 5 and Figure 6 The padding ribs include a lower padding rib 64, a left padding rib 65 and a right padding rib 66. The lower padding rib 64 is arranged at the middle of the lower shipboard 51, the left padding rib 65 is arranged at the lower shipboard 51 or the left side wall 52, and the right padding rib 66 is arranged at the lower shipboard 51 or the right side wall 53. In this embodiment, the lower padding rib 64, the left padding rib 65 and the right padding rib 66 are preferably arranged at the lower shipboard 51, and the lower padding rib 64, the left padding rib 65 and the right padding rib 66 are used to lift the chain element 20 and suspend it in the air, so that the lower side of the chain element 20 does not completely contact the lower shipboard 51, thereby reducing the contact area, reducing the friction of the zipper, and improving the wear resistance and smoothness of the zipper.

[0037] Preferably, the horizontal height layout of the recess 61, the side guide ribs and the pad ribs in the slider body of the present embodiment is arranged from top to bottom in sequence.

[0038] In addition, refer to Figure 5 and Figure 6 The matching chain tooth 20 is provided with a groove portion 21 for winding the suture 70. While the suspended chain tooth 20 is raised, the suture 70 sinks and is wound in the groove portion 21, and finally the suture 70 is not in contact with the lower ship plate 51, thereby greatly reducing the risk of the suture 70 being worn off and greatly improving the number of repeated pulling and closing and the service life of the product.

[0039] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
