Description

Technical Field

[0001] This utility model relates to the field of zippers, and more specifically to a zipper. Background Technology

[0002] A zipper consists of teeth, a slider, and fabric tape. The teeth are the most crucial part of the zipper, determining its lateral strength. Typically, each zipper tape has two rows of teeth, arranged alternately, which engage or disengage by sliding the slider. The slider controls the opening and closing of the zipper. It holds the teeth on both sides and engages or disengages them by sliding. After prolonged use, the slider is prone to damage, causing the zipper head to fail to properly close the two teeth. Replacing the zipper head in this case requires disassembling the sewn edge of the zipper and replacing the entire zipper, or replacing the slider directly and then sewing it back together. This makes replacing the damaged slider inconvenient. Utility Model Content

[0025] refer to Figure 1 , 2 Examples of zippers that are easy to install are detailed in sections 4 and 5:

[0026] A zipper includes two mating teeth and a fabric tape for mounting the two teeth. The fabric tape is used for sewing to fix the teeth. It also includes a zipper head for controlling the opening and closing of the two teeth. The zipper head clamps the teeth on both sides and achieves engagement or disengagement of the teeth by sliding.

[0027] The zipper pull includes a first zipper pull 11 and a second zipper pull 21. Symmetrical protrusions are provided on the edges of both the first zipper pull 11 and the second zipper pull 21. After installation, the symmetrical protrusions at both ends of the first zipper pull 11 and the second zipper pull 21 are used to clamp the chain teeth on both sides for engagement. A support core is provided on the first zipper pull 11, which is used to separate the engaged chain teeth during sliding. A first hole 12 is provided on the support core in the middle of the first zipper pull 11. A first protrusion 22 is provided on the second zipper pull 21. The first protrusion 22 is snapped into the first hole 12, allowing for quick installation of the separated first zipper pull 11 and second zipper pull 21 by snapping the first protrusion 22 into the first hole 12. Zipper heads are prone to damage after long-term use, and repair is inconvenient after damage. It is necessary to remove the zipper and sew a new zipper onto the position where the zipper needs to be installed. Existing zipper heads are also inconvenient to replace. Therefore, a snap-fit ​​zipper head is adopted to facilitate the replacement of damaged zipper heads and increase user convenience.

[0028] refer to Figure 2 and 5 Detailed embodiments further enhancing the fixation of the relative positions of the first zipper pull 11 and the second zipper pull 21:

[0029] The upper end face of the first zipper 11 is provided with two positioning holes 15, and the lower end face of the second zipper 21 is provided with a second protrusion 25 corresponding to the two positioning holes 15. The two second protrusions 25 are inserted into the two positioning holes 15 to restrict the relative rotation of the first zipper 11 and the second zipper 21, thus playing a limiting role. At the same time, it can also ensure that the positions of the first zipper 11 and the second zipper 21 are fixed, and can control the opening and closing of the two chain teeth.

[0030] refer to Figure 3 and 5 A detailed embodiment for improving the fixation of the first zipper pull 11 and the second zipper pull 21:

[0031] An annular groove 14 is provided on the inner wall of the first hole 12, and a protruding ring 24 corresponding to the annular groove 14 is provided on the outer wall of the first protrusion 22. When the first pull head 11 and the second pull head 21 are engaged, the annular groove 14 limits the protruding ring 24, thereby enhancing the firmness of the engagement of the first pull head 11 and the second pull head 21 and preventing the first pull head 11 and the second pull head 21 from separating.

[0032] refer to Figure 3 and 5A detailed embodiment for improving the fixation of the first zipper pull 11 and the second zipper pull 21:

[0033] The annular groove 14 is an arc-shaped groove with a semi-circular cross-section, and the convex ring 24 is an arc-shaped protrusion with a semi-circular cross-section. When the semi-circular arc-shaped protrusion is inserted into the semi-circular arc-shaped groove, it can be guided by the arc shape to prevent interference and jamming during installation, which would prevent the first pull head 11 and the second pull head 21 from being engaged. The first protrusion 22 is made of elastic metal material, which can ensure the installation of the first pull head 11 and the second pull head 21.

[0034] refer to Figure 5 Detailed description of an embodiment that ensures the first protrusion 22 is installed in the first hole 12:

[0035] The first protrusion 22 and the protruding ring 24 are evenly distributed with multiple slots 26. By setting multiple slots 26, the deformation of the first protrusion 22 and the protruding ring 24 is increased, and greater deformation can occur, ensuring that the first protrusion 22 and the protruding ring 24 can be inserted into the first hole 12 to complete the installation.

[0036] refer to Figure 1 , 4 Sections 6 and 7 detail embodiments for fixing the first zipper pull 11 and the second zipper pull 21:

[0037] The second zipper pull 21 and the first protrusion 22 are provided with a second hole 23, which is a through hole. The first zipper pull 11 is provided with a third hole 13 corresponding to the first hole 12. The first hole 12 and the third hole 13 are stepped holes, and the third hole 13 is a threaded hole. A stud 32 is threadedly connected to the third hole 13, and a pressure plate 31 is provided on the stud 32. Thus, when installing the first zipper pull 11 and the second zipper pull 21, the first protrusion 22 on the second zipper pull 21 is inserted into the first hole 12, the two second protrusions 25 are inserted into the two positioning holes 15, the stud 32 is passed through the second hole 23 and connected to the third hole 13, and the pressure plate 31 is attached to the second zipper pull 21 to complete the fixation of the first zipper pull 11 and the second zipper pull 21, so that the zipper pull can be used more reliably.

[0038] refer to Figure 7 Detailed description of an embodiment that ensures the pressure plate 31 fully presses against the second pull head 21:

[0039] The third hole 13 is a threaded through hole, which can prevent the stud 32 from coming loose during vibration due to compressed air in the third hole 13 being a blind hole. It can also ensure that the stud 32 rotates to fit the pressure plate 31 against the second pull head 21, ensuring that the pressure plate 31 fully presses the second pull head 21.

[0040] refer to Figure 6Detailed examples of women's clothing pull tabs:

[0041] The pressure plate 31 is provided with a connecting block 33, which is a cross-shaped arc plate. A pull tab or pull rope can be installed through the cross-shaped arc plate connecting block 33, so that the finger can pull the connecting block 33 to move, thereby driving the second pull head 21 and the first pull head 11 to complete the engagement and disengagement of the chain teeth.

[0042] refer to Figure 1 and 6 Detailed description of an embodiment that ensures the pressure plate 31 is secure to the second pull head 21:

[0043] The pressure plate 31 is a circular plate, and the diameter of the pressure plate 31 is larger than the diameter of the second hole 23. This ensures that when the pressure plate 31 is in contact with the second zipper pull 21, it can press on the second zipper pull 21 and limit the second zipper pull 21 in the axial direction of the pressure plate 31, preventing the second zipper pull 21 from separating from the first zipper pull 11, which would render the zipper unusable.

[0044] refer to Figure 3 , 5 Sections 7 and 8 detail embodiments that ensure the connection between stud 32 and the third hole 13:

[0045] The diameter of the first hole 12 is larger than the diameter of the third hole 13, and the diameter of the second hole 23 is larger than the diameter of the third hole 13, thereby ensuring that the stud 32 can pass through the second hole 23 and be installed into the third hole 13, so as to fix the second pull head 21 to the first pull head 11.
