Description

Technical Field

[0001] This application relates to the field of zipper technology, and more particularly to a zipper. Background Technology

[0002] A zipper consists of teeth, a slider, and top and bottom stops (front and back stops) or locking mechanisms. The teeth are the key component, directly determining the zipper's lateral pulling strength. Generally, a zipper has two straps, each with a row of teeth, arranged alternately. The slider grips the teeth on both sides, and by sliding along the loops, the teeth can be engaged or disengaged.

[0003] In existing solutions, the spacing between adjacent teeth on the same row of chain belts and the spacing between adjacent teeth on another row of chain belts are subject to strict requirements. The error range cannot be too large, otherwise the teeth on both sides will not be able to mesh with each other. With the accumulation of errors, the two chain belts will be of different lengths. In addition, the size of each tooth in the two rows of chain belts must also be equal, which means that there is no universality between chain teeth of different sizes. Summary of the Invention

[0026] like Figure 1 As shown, A zipper includes a first chain fabric 1, a second chain fabric 2, and a zipper pull 3; a first chain tooth 4 is connected to the first chain fabric 1; a second chain tooth 5 is connected to the second chain fabric 2; the zipper pull 3 can move the first chain tooth 4 closer to or further away from the second chain tooth 5; a first connecting component 41 is provided on the first chain tooth 4, and a second connecting component 51 is provided on the second chain tooth 5 corresponding to the position of the first connecting component 41, and the first connecting component 41 can engage with the second connecting component 51.

[0027] Its beneficial effects are: the size and position of the first chain tooth 4 and the second chain tooth 5 do not need to correspond exactly; it is only necessary for the first connecting component 41 to be able to mesh with the second connecting component 51, which improves the versatility of the chain teeth and facilitates the processing and production of the chain teeth; it avoids the situation in traditional zippers where the meshing teeth are wrong and the two chain straps are of different lengths, thus improving the aesthetics of the zipper.

[0028] like Figure 1 As shown, in the first embodiment, several first chain teeth 4 are connected to the first chain fabric 1, and several second chain teeth 5 are connected to the second chain fabric 2.

[0029] like Figure 7 As shown, in the second embodiment, the first chain tooth 4 is connected to the first chain cloth 1 along the length direction of the first chain cloth 1, and the second chain tooth 5 is connected to the second chain cloth 2 along the length direction of the second chain cloth 2.

[0030] like Figure 2 As shown, Preferably, the first connection component 41 includes: First connecting end 411; wherein the first connecting end 411 protrudes from the plane where the first chain tooth 4 is located; The first protrusion 412 is disposed on one side of the first connecting end 411; The first protrusion 413 is disposed on one side of the first protrusion 412.

[0031] Preferably, a first groove 4111 is provided on the first connecting end 411; A first slot 414 is provided between the first connecting end 411 and the first protrusion 412; A second slot 415 is provided between the first protrusion 412 and the first tooth 413.

[0032] like Figures 3-4 As shown, Preferably, the second connection component 51 includes: Second connecting end 511; wherein the second connecting end 511 protrudes from the plane where the second chain tooth 5 is located; The second protrusion 512 is disposed on one side of the second connecting end 511 and can be accommodated by the first slot 414. The second protrusion 513 is disposed on one side of the second protrusion 512 and can engage with the first groove 4111.

[0033] Preferably, the second connecting end 511 is provided with a second groove 5111 that can engage with the first protrusion 413; A third slot 514 capable of accommodating the first protrusion 412 is provided between the second connecting end 511 and the second protrusion 512; A fourth slot 515 is provided between the second protrusion 512 and the second tooth 513, which can engage with the first connecting end 411.

[0034] It should be noted that zippers are generally subjected to tension in two directions: one is the tension perpendicular to the zipper teeth, and the other is the tension parallel to the zipper teeth.

[0035] When the zipper is pulled up, the first protruding tooth 413 engages with the second groove 5111, and the second protruding tooth 513 engages with the first groove 4111, so that the first chain tooth 4 and the second chain tooth 5 have good tensile strength in both the direction perpendicular to and parallel to the chain tooth, which can prevent the chain tooth engagement from loosening. Furthermore, when the zipper is zipped up, the third slot 514 accommodates the first protrusion 412 and the first slot 414 accommodates the second protrusion 512, further enhancing the tensile strength of the first chain tooth 4 and the second chain tooth 5 in the direction parallel to the chain tooth. Furthermore, when the zipper is zipped up, the first protrusion 412 extends unobstructed into the third slot 514, and the second protrusion 512 extends unobstructed into the first slot 414, thereby quickly calibrating the relative positions of the first chain tooth 4 and the second chain tooth 5, facilitating the rapid positioning of the first chain tooth 4 and the second chain tooth 5, and enabling the first chain tooth 4 and the second chain tooth 5 to engage quickly and accurately.

[0036] In this embodiment, the outer surfaces of the first protrusion 413 and the second protrusion 513 are configured as arc-shaped; correspondingly, the inner surfaces of the second groove 5111 and the first groove 4111 are configured as arc-shaped, forming arc-shaped grooves; the first protrusion 412 and the second protrusion 513 are configured as rectangular; the third slot 514 and the first slot 414 are configured as rectangular, forming rectangular grooves.

[0037] In addition, the first slot 414, the first protrusion 412, and the first tooth 413 are arranged in a stepped manner within the first connecting assembly 41. Specifically, the first slot 414 is lower than the first protrusion 412, and the first protrusion 412 is lower than the first tooth 413.

[0038] The second slot 415, the second protrusion 512, and the second tooth 513 are arranged in a stepped manner within the second connecting assembly 51. Specifically, the second tooth 513 is lower than the second protrusion 512, and the second protrusion 512 is lower than the second slot 415.

[0039] like Figure 6 As shown, Preferably, the slider 3 includes a first through groove 31 and a second through groove 32; The first through groove 31 is located at the left end of the pull head 3, allowing the first chain cloth 1 to pass through; The second through slot 32 is located at the right end of the pull head 3, allowing the second chain cloth 2 to pass through.

[0040] Preferably, the zipper 3 includes a connector 33 disposed in its middle, which enables the first chain tooth 4 and the second chain tooth 5, which are engaged together, to separate from each other.

[0041] like Figures 5-6 As shown, Preferably, the upper end of the connector 33 is provided with a first locking piece 331 and a second locking piece 332 from left to right; A first slot 333 that can match the first protrusion 412 is provided between the first clip 331 and the second clip 332; The first card 331 can be matched with the first card slot 414; the second card 332 can be matched with the second card slot 415.

[0042] Preferably, the lower end of the connector 33 is provided with a third locking piece 334 and a fourth locking piece 335 from left to right; A second slot 336 that can match the second protrusion 512 is provided between the third clip 334 and the fourth clip 335; The third card part 334 can be matched with the third card slot 514; the fourth card part 335 can be matched with the fourth card slot 515.

[0043] The following provides further details on how to use this zipper: When the zipper is pulled up (i.e., the first zipper tooth 4 and the second zipper tooth 5 are brought closer to each other until they engage under the action of the zipper head 3), the first zipper tooth 4 approaches the second zipper tooth 5 until they engage under the pressure of the connector 33, the first protrusion 413 engages with the second groove 5111, the second protrusion 513 engages with the first groove 4111, the first protrusion 412 extends into the third slot 514 without obstruction, and the second protrusion 512 extends into the first slot 414 without obstruction. When the zipper is pulled down (i.e., the first chain tooth 4 and the second chain tooth 5 are moved away from each other until they are separated under the action of the zipper 3), the first chain tooth 4 and the second chain tooth 5, which are engaged with each other, are separated under the action of the connector 33. The first protrusion 413 moves away from the second groove 5111 until it is disengaged, the second protrusion 513 moves away from the first groove 4111 until it is disengaged, the first protrusion 412 moves away from the third slot 514, and the second protrusion 512 moves away from the first slot 414.
