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] Many new types of zippers have appeared on the market. One type connects the zipper teeth on one zipper fabric to the zipper teeth on another fabric fabric using a "guide rail" and a clip that engages with the "guide rail". This new type of zipper breaks away from the shape and structure of traditional zippers, improving aesthetics compared to traditional zippers, and is especially suitable for connecting two pieces of fabric that are not on the same plane.

[0004] However, the aforementioned new type of zipper has at least the following problems:

[0005] This new type of zipper has poor ability to withstand forces perpendicular to the zipper teeth. Applying excessive force perpendicular to the zipper teeth to teeth that are already interlocked may cause the zipper teeth on one side to detach from the zipper teeth on the other side, resulting in zipper failure. Summary of the Invention

[0006] The purpose of this application is to provide a zipper that solves at least one of the aforementioned technical problems.

[0007] A zipper, comprising:

[0008] The first and second chain teeth that can be locked together;

[0009] The first chain tooth is provided with a guide rail, and the left and right ends of the first chain tooth are respectively provided with limiting parts, and a slot is provided between the limiting parts and the guide rail.

[0010] The second chain tooth has a locking part at both ends. The locking part can lock into the guide rail part, and the locking part can be located inside the slot part and the limiting part can be located on one side of the locking part.

[0011] The interlocking parts are provided with slots for accommodating the guide rails;

[0012] The first chain tooth is connected to the side of the first chain cloth;

[0013] A second chain cloth is connected to the side of the second chain tooth;

[0014] The ends of the first and second chain teeth are provided with bottom stops;

[0015] The first and second chain teeth are equipped with pull tabs that allow the first and second chain teeth to engage or disengage.

[0016] Its beneficial effects are: the zipper has strong stability. When subjected to one or more forces in the x and y directions, the first and second chain teeth, which are already interlocked, are not easily separated from each other under the interference of the above forces, thereby preventing zipper failure and improving the overall lifespan of the zipper.

[0017] In some embodiments, the guide rail includes:

[0018] The connecting end is connected to the first chain tooth at one end;

[0019] The guide end is connected to the other end of the connecting end;

[0020] The left side of the guide end is provided with a first terminal and a second terminal from bottom to top;

[0021] The right side of the guide end is provided with a third terminal and a fourth terminal from bottom to top;

[0022] In some embodiments, the limiting portion includes a first limiting end and a second limiting end located at the left and right ends of the first chain tooth, respectively; a first limiting protrusion is provided on the end of the first limiting end facing the guide rail portion; and a second limiting protrusion is provided on the end of the second limiting end facing the guide rail portion.

[0023] Its beneficial effects are: the first limiting protrusion, together with the guide rail, limits the locking part; the second limiting protrusion, together with the guide rail, limits the locking part.

[0024] In some embodiments, the slot portion includes a first slot and a second slot, the first slot being located between the first limiting protrusion and the guide rail portion, and the second slot being located between the second limiting protrusion and the guide rail portion.

[0025] In some embodiments, the snap-fit ​​portion includes a first snap-fit ​​protrusion and a second snap-fit ​​protrusion;

[0026] An opening is provided between the first and second locking protrusions for the guide rail to enter and exit.

[0027] In some embodiments, the left and right ends of the first snap-fit ​​protrusion are respectively provided with a first snap-fit ​​terminal and a second snap-fit ​​terminal;

[0028] The second snap-fit ​​protrusion has a third snap-fit ​​terminal and a fourth snap-fit ​​terminal on its left and right ends, respectively;

[0029] The first snap-fit ​​terminal can engage with the first limiting protrusion;

[0030] The second terminal can engage with the first terminal;

[0031] The third terminal can engage with the third terminal;

[0032] The fourth locking terminal can engage with the second limiting protrusion.

[0033] In some implementations, the zipper pull includes:

[0034] The separation section is located inside the slider and is used to separate the first chain tooth and the second chain tooth from each other.

[0035] The first cloth passage is located at the right end of the pull head and is used to allow the first chain cloth to pass through.

[0036] The second cloth passage is located at the left end of the pull head and is used to allow the second chain cloth to pass through.

[0037] In some implementations, the size of the slider gradually decreases from one end to the other.

[0038] Its beneficial effect is that when the zipper is zipped up, the gradually decreasing space of the zipper head will continuously squeeze the second zipper tooth, causing the second zipper tooth to engage with the first zipper tooth.

[0039] In some embodiments, the separating portion includes a first mating end located at its lower end and a second mating end located at its lower end;

[0040] The shape of the first mating end can match the shape of the first chain tooth;

[0041] The shape of the second mating end can match the shape of the second chain tooth.

[0042] The first matching end includes a first baffle and a second baffle. The shape and position of the first baffle can match the first slot, and the shape and position of the second baffle can match the second slot.

[0043] The second matching end includes a third baffle and a first groove and a second groove located on both sides of the third baffle respectively; the shape and position of the first groove can match the first snap-fit ​​protrusion, and the shape and position of the second groove can match the second snap-fit ​​protrusion.
