Description

Technical Field

[0001] This application relates to the field of zipper technology, and in particular to a zipper anti-loosening structure and a zipper using the same. 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 pull tabs, the teeth on both sides can be engaged or disengaged.

[0003] After zippers engage, they are generally subjected to forces in two directions: one force is parallel to the zipper fabric, and the other force is perpendicular to the zipper fabric. In the present technology, zippers are prone to detaching from each other after being subjected to these two forces, or they wear out rapidly under external force, affecting the service life of the zipper. Summary of the Invention

[0004] The purpose of this application is to provide a zipper anti-loosening structure and a zipper using the same, in order to solve at least one of the above-mentioned technical problems.

[0005] A zipper anti-detachment structure includes a first zipper tooth and a second zipper tooth that can mesh with each other; the first zipper tooth or the second zipper tooth is provided with a first groove and a second groove respectively, and the second zipper tooth or the first zipper tooth is provided with a first protrusion and a second protrusion respectively; the first protrusion can be engaged with the first groove for preventing the zipper from detaching in the x and y directions; the second protrusion can be connected to the second groove for preventing the zipper from detaching in the x and y directions.

[0006] Its beneficial effect is that the engagement of the first and second chain teeth is not easy to disengage when the zipper is subjected to force in either the x or y direction, so that the zipper has a good anti-disengagement effect in both directions.

[0007] In some embodiments, the first slot is an arc-shaped slot, and one end of the arc-shaped slot is provided with a first opening for the first protrusion to enter and exit; the left and right sides of the first opening are respectively a first connecting part and a second connecting part.

[0008] Its beneficial effect is that the first protrusion engages or disengages with the arc-shaped groove by entering and exiting the first opening, so that the zipper has a better anti-slip effect in the y direction.

[0009] In some embodiments, the second connecting portion has a first contact end and a second contact end from top to bottom in the direction of the first opening, and the thickness of the first contact end is smaller than that of the second contact end.

[0010] Its beneficial effect is that the thickness of the first contact end is smaller than that of the second contact end. Therefore, when the first protrusion enters or exits the first opening and engages or disengages with the arc-shaped groove, the first contact end is more likely to undergo elastic deformation, which facilitates the first protrusion entering or exiting the first opening.

[0011] In some embodiments, one end of the second slot is connected to a limiting part, and a groove end is provided at the connection between the second slot and the limiting part, with one end of the limiting part bent toward the opening of the groove end.

[0012] In some embodiments, the first protrusion includes a first connecting rod portion and a first tooth portion connected thereto, the first tooth portion being an arc-shaped protrusion that matches the shape of the arc-shaped groove, and the diameter of the first tooth portion being larger than the diameter of the first opening.

[0013] Its beneficial effect is that the diameter of the first protruding tooth is larger than the diameter of the opening. Therefore, when the first protruding tooth enters or exits the first opening, it will squeeze the first connecting part and the second connecting part to undergo elastic deformation, thereby opening outward from the first opening.

[0014] In some embodiments, a movable gap is provided between the connecting rod and the first connecting part and the second connecting part, respectively.

[0015] Its beneficial effects are: when the zipper is subjected to an X-direction tension, the connecting rod has sufficient clearance to move between the first connecting part and the second connecting part, which prevents the zipper from disengaging when subjected to an X-direction tension, and on this basis, prevents the parts from being constantly locked together, thus preventing wear and tear on the parts and improving the service life of the relevant parts.

[0016] In some embodiments, the second protrusion includes a second connecting rod portion and a second tooth portion connected thereto, the second tooth portion being bent to the right side of the second connecting rod portion and capable of engaging with the groove end.

[0017] Its beneficial effect is that the second convex tooth engages with the groove end, giving the zipper a good anti-slip effect in the x-direction.

[0018] In some embodiments, a third slot is provided between the first protrusion and the second protrusion, allowing the second connecting portion to enter and exit.

[0019] A zipper employs a zipper anti-detachment structure, wherein at least two sets of zipper anti-detachment structures are provided inside the zipper, a first zipper tooth is connected to a first zipper fabric, and a second zipper tooth is connected to a second zipper fabric; the zipper also includes a zipper head that allows the first zipper tooth and the second zipper tooth to mesh or separate from each other.

[0020] In some embodiments, a baffle is provided in the middle of the zipper head to allow the first chain tooth and the second chain tooth to mesh or separate.

[0021] The left and right ends of the zipper have a first gap and a second gap for the first chain cloth and the second chain cloth to pass through, respectively. Attached Figure Description

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] like Figure 1 As shown,

[0036] A zipper anti-detachment structure includes a first zipper tooth 1 and a second zipper tooth 2 that can mesh with each other; a first groove 01 and a second groove 02 are respectively provided on the first zipper tooth 1 or the second zipper tooth 2, and a first protrusion 03 and a second protrusion 04 are respectively provided on the second zipper tooth 2 or the first zipper tooth 1; the first protrusion 03 can be engaged with the first groove 01 for preventing the zipper from detaching in the x and y directions; the second protrusion 04 can be connected to the second groove 02 for preventing the zipper from detaching in the x and y directions.

[0037] Its beneficial effect is that the engagement of the first chain tooth 1 and the second chain tooth 2 is not easy to disengage when the zipper is subjected to force in either the x or y direction, so that the zipper has a good anti-disengagement effect in both directions.

[0038] It should be noted that the y-direction is perpendicular to the chain fabric direction. Figure 1 The middle direction is vertical, and the x-direction is parallel to the chain fabric direction. Figure 1 The middle part is in the horizontal direction. In particular, the first protrusion 03, which is engaged with the first slot 01, has a better anti-detachment effect in the y-direction, and the second protrusion 04, which is connected to the second slot 02, has a better anti-detachment effect in the x-direction.

[0039] like Figure 2 As shown,

[0040] Preferably, the first slot 01 is an arc-shaped slot, and one end of the arc-shaped slot is provided with a first opening 011 for the first protrusion 03 to enter and exit; the left and right sides of the first opening 011 are respectively the first connecting part 012 and the second connecting part 013.

[0041] Its beneficial effect is that the first protrusion 03 engages or disengages with the arc-shaped groove by entering and exiting the first opening 011, so that the zipper has a better anti-loosening effect in the y direction.

[0042] Preferably, the second connecting portion 013, from top to bottom, in the direction of the first opening 011, is a first contact end 0131 and a second contact end 0132, and the thickness of the first contact end 0131 is less than that of the second contact end 0132.

[0043] Its beneficial effect is that the thickness of the first contact end 0131 is smaller than that of the second contact end 0132. Therefore, when the first protrusion 03 enters or exits the first opening 011 and engages or disengages with the arc groove, the first contact end 0131 is more likely to undergo elastic deformation, which facilitates the first protrusion 03 to enter or exit the first opening 011.

[0044] Preferably, one end of the second slot 02 is connected to the limiting part 05, and a groove end 06 is provided at the connection between the second slot 02 and the limiting part 05. One end of the limiting part 05 is bent toward the opening direction of the groove end 06.

[0045] like Figure 3 As shown,

[0046] Preferably, the first protrusion 03 includes a first connecting rod portion 031 and a first tooth portion 032 connected thereto. The first tooth portion 032 is an arc-shaped protrusion that matches the shape of the arc-shaped groove, and the diameter of the first tooth portion 032 is larger than the diameter of the first opening 011.

[0047] Its beneficial effect is that the diameter of the first toothed part 032 is larger than the opening diameter. Therefore, when the first toothed part 032 enters and exits the first opening 011, it will squeeze the first connecting part 012 and the second connecting part 013 to undergo elastic deformation, thereby opening outward from the first opening 011.

[0048] Preferably, the connecting rod portion is provided with movable gaps between itself and the first connecting portion 012 and the second connecting portion 013, respectively.

[0049] Its beneficial effects are: when the zipper is subjected to an X-direction tension, the connecting rod has sufficient clearance to move between the first connecting part 012 and the second connecting part 013, which prevents the zipper from disengaging when subjected to an X-direction tension, and on this basis, prevents the parts from being constantly locked together, thus preventing wear of the parts and improving the service life of the relevant parts.

[0050] Preferably, the second protrusion 04 includes a second connecting rod portion 041 and a second tooth portion 042 connected thereto. The second tooth portion 042 bends to the right side of the second connecting rod portion 041 and can engage with the groove end 06.

[0051] Its beneficial effect is that the second convex tooth 042 engages with the groove end 06, which makes the zipper have a good anti-slip effect in the x direction.

[0052] Preferably, a third slot 07 is provided between the first protrusion 03 and the second protrusion 04, which allows the second connecting part 013 to enter and exit.

[0053] like Figure 4 , 7 As shown, the first embodiment

[0054] A zipper with a zipper anti-detachment structure, wherein at least two sets of zipper anti-detachment structures are provided inside the zipper, a first zipper tooth 1 is connected to a first zipper cloth 3, and a second zipper tooth 2 is connected to a second zipper cloth 4; the zipper also includes a zipper head 5 for engaging or disengaging the first zipper tooth 1 and the second zipper tooth 2.

[0055] Preferably, the middle part of the pull head 5 is provided with a baffle 51 that allows the first chain tooth 1 and the second chain tooth 2 to mesh or separate.

[0056] The left and right ends of the zipper 5 are respectively provided with a first gap 52 and a second gap 53 for the first chain cloth 3 and the second chain cloth 4 to pass through.

[0057] It should be noted that, on the one hand, a whole first chain tooth 1 can be set along the length direction of the first chain fabric 3, and at the same time, a whole second chain tooth 2 can be set along the length direction of the second chain fabric 4. On the other hand, several first chain teeth 1 can be set at equal intervals along the length direction of the first chain fabric 3, and several second chain teeth 2 can be set at equal intervals along the length direction of the second chain fabric 4.

[0058] Specifically, the upper end of the baffle 51 is provided with a first separating tooth 511 and a second separating tooth 512 from left to right, and the lower end of the baffle 51 is provided with a third separating tooth 513 and a fourth separating tooth 514 from right to left. The left end of the first separating tooth 511 is provided with a first receiving cavity 515, the first separating tooth 511 and the second separating tooth 512 are provided with a second receiving cavity 516, the right end of the second separating tooth 512 is provided with a third receiving cavity 517; the right end of the third separating tooth 513 is provided with a fourth receiving cavity 518, the third separating tooth 513 and the fourth separating tooth 514 are provided with a fifth receiving cavity 519, and the left end of the fourth separating tooth 514 is provided with a sixth receiving cavity 520.

[0059] The following is a detailed explanation of the specific engagement of the zipper:

[0060] When the zipper engages, the baffle 51 of the zipper head 5 presses the first chain tooth 1 close to the second chain tooth 2 for engagement. The first protrusion 03 enters the first opening 011 and engages with the arc-shaped groove. While entering the first opening 011, the first protrusion 03 presses the first connecting part 012 and the second connecting part 013 respectively, causing the first connecting part 012 and the second connecting part 013 to undergo elastic deformation. In particular, the elastic deformation at the first contact end 0131 is greater because it has a thinner thickness. The second protrusion 04 enters the second groove 02. The second connecting rod part 041 is compressed by the inner wall of the second groove 02 and undergoes elastic deformation, causing the second protruding tooth part 042 to engage with the groove end 06.

[0061] When the zipper disengages, the baffle 51 causes the first chain tooth 1 and the second chain tooth 2 to separate from each other. Specifically, the first separating tooth 511 enters the second groove 02 on the first chain tooth 1, the second separating tooth 512 enters the third groove 07 on the first chain tooth 1, the third separating tooth 513 enters the second groove 02 on the second chain tooth 2, and the fourth separating tooth 513 enters the third groove 07 on the second chain tooth 2. The first receiving cavity 515 can accommodate the first groove 01 on the first chain tooth 1, the second receiving cavity 516 can accommodate the second protrusion 04 on the first chain tooth 1, the third receiving cavity 517 can accommodate the first protrusion 03 on the first chain tooth 1, the fourth receiving cavity 518 can accommodate the first groove 01 on the second chain tooth 2, the fifth receiving cavity 519 can accommodate the second protrusion 04 on the second chain tooth 2, and the sixth receiving cavity 520 can accommodate the first protrusion 03 on the second chain tooth 2.

[0062] like Figure 5 As shown, in the second embodiment of this application, based on the first embodiment, the second protrusion 04 can penetrate into the second groove 02, and the second protrusion 04 has an movable gap in the second groove 02. The side of the first contact end 0131 near the second groove 02 has the same curvature as the inner side of the first contact end 0131.

[0063] like Figure 6 As shown, in the third embodiment of this application, based on the second embodiment, the first contact end 0131 is perpendicular to the first chain tooth 1, and there is a gap between the upper end of the first contact end 0131 and the top of the first protruding tooth 032.

[0064] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of the appended claims. In this case, all details can be replaced with equivalent elements, and the materials, shapes, and sizes can also be arbitrary.
