Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a quick-release zipper. Background Technology

[0002] Modern zipper manufacturing processes are constantly being optimized. For example, for closed-end zippers, the left and right zipper straps are connected together at the end by a tail stop. The manufacturing process for open-end zippers is also being improved, such as using hot-melt polymer materials to manufacture the zipper teeth and reshaping them using molds to form the tail stop component, thus improving the quality and durability of the zipper. Currently, zippers rely on zippers for disassembly, but some garments have zippers on the back, requiring users to reach for the zipper to unlock them when taking off their clothes, which is cumbersome. Therefore, we propose a quick-release zipper. Utility Model Content

[0003] The main purpose of this invention is to provide a quick-release zipper that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A quick-release zipper includes an upper zipper tooth, an upper wide tooth connected to the upper zipper tooth by tooth engagement, a middle tooth connected to the upper wide tooth by tooth engagement, a lower wide tooth connected to the middle tooth by tooth engagement, and a lower zipper tooth connected to the lower wide tooth by tooth engagement.

[0006] Preferably, there are multiple upper chain teeth and multiple lower chain teeth, and the multiple upper chain teeth and the multiple lower chain teeth are connected by tooth biting.

[0007] Preferably, the upper chain teeth and the lower chain teeth have identical structures.

[0008] Preferably, there are multiple intermediate teeth, and the multiple intermediate teeth are connected by tooth biting. The biting size of the intermediate teeth is 1.3 mm, ensuring that the biting strength between them is 70 to 90 Newtons. The exposed outer surface of the intermediate teeth is provided with a tearing arrow.

[0009] Preferably, the upper and lower wide teeth have identical structures.

[0010] Preferably, the upper and lower ends of the middle teeth are respectively connected to the upper and lower chain teeth through upper and lower wide teeth to ensure the strength at the interface.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, the quick-release zipper allows the user to quickly tear open the zipper, making it easier to unzip zippers located on the back, thus quickly removing clothing and avoiding the hassle of relying on others for help. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example 1:

[0019] like Figure 1-3 As shown, a quick-release zipper includes an upper zipper tooth 1, an upper wide tooth 2 connected to the upper zipper tooth 1 by tooth engagement, a middle tooth 3 connected to the upper wide tooth 2 by tooth engagement, a lower wide tooth 4 connected to the middle tooth 3 by tooth engagement, and a lower zipper tooth 5 connected to the lower wide tooth 4 by tooth engagement.

[0020] Multiple upper chain teeth 1 and multiple lower chain teeth 5 are provided, and the multiple upper chain teeth 1 and the multiple lower chain teeth 5 are connected by tooth biting;

[0021] Specifically, the upper chain teeth 1 and the lower chain teeth 5 are arranged in multiple ways to achieve the required length, and the structure is fixed by strong biting.

[0022] The upper chain tooth 1 and the lower chain tooth 5 have the same structure;

[0023] There are multiple intermediate teeth 3, and the multiple intermediate teeth 3 are connected by tooth bite. The bite size of the intermediate teeth 3 is 1.3 mm, ensuring that the bite strength between them is 70 to 90 Newtons. The exposed outer surface of the intermediate teeth 3 is provided with tearing arrows.

[0024] Specifically, the bite size of the middle teeth 3 is set to avoid excessive bite force between the middle teeth 3, ensuring that the bite force is between 70 and 90 Newtons, so that the user can easily release the teeth when applying appropriate force, and the teeth will not be pulled apart by a small external force. The tearing arrow serves both a decorative function and an indication of the tearing direction.

[0025] The structures of upper wide tooth 2 and lower wide tooth 4 are completely identical;

[0026] The upper and lower ends of the middle tooth 3 are connected to the upper chain tooth 1 and the lower chain tooth 5 respectively by the upper wide tooth 2 and the lower wide tooth 4 to ensure the strength at the interface;

[0027] Specifically, the upper wide tooth 2 and the lower wide tooth 4 are designed to ensure that the connection between the upper chain tooth 1 and the lower chain tooth 5 is strong enough to prevent tearing, thus ensuring a high connection strength between the upper and lower ends and preventing the connection from being easily pulled apart.

[0028] It should be noted that this utility model is a quick-release zipper. When using it, if the zipper is pulled up... Figure 1 As shown, the upper wide tooth 2 separates the upper chain tooth 1 and the middle tooth 3, and the lower wide tooth 4 separates the lower chain tooth 5 and the middle tooth 3. The upper wide tooth 2 and the lower wide tooth 4 serve as a transition. This structure ensures strong tooth engagement at the interface between the upper chain tooth 1 and the lower chain tooth 5. When untying, the user only needs to grab the clothing on both sides of the middle tooth 3 and pull. A pulling force of 70 to 90 Newtons is enough to tear it apart, thus quickly and easily tearing and untying the clothing. The operation is simple and convenient.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
