Description

Technical Field

[0001] This application relates to the technical field of zippers, and in particular to a durable zipper that prevents edge warping. Background Art

[0002] A zipper is a connecting piece that relies on continuously arranged teeth to join or separate items, and is now widely used in clothing, bags, tents, etc. Zippers can be classified by material into nylon zippers, resin zippers, and metal zippers. Among them, metal zippers have a longer service life, but also have the highest manufacturing cost and the most complex processing technology, and are generally used more frequently on clothing such as suitcases and pants. Structurally, a zipper consists of teeth, a slider, upper and lower stops (front and rear codes) or locking parts, etc. Among them, the slider is the key part. The slider clamps the teeth on both sides and slides along the pull tab, enabling the teeth on both sides to mesh or disengage from each other.

[0003] The slider has a pull tab, which can be designed into various geometric shapes and connected to the slider body or connected to the pull head body through an intermediate piece to realize the opening and closing of the zipper. The pull tab is directly connected to the slider body or connected to the pull head body through an intermediate piece. The design of these intermediate pieces, especially the elastic piece, is the key to enabling the pull tab to fit on the surface of the slider when not in use. As an elastic intermediate piece, when the pull tab is flipped, this pressing force can make the pull tab not only perpendicular to the surface of the slider, but also automatically fit on the slider. However, currently on the market, the elastic pieces and the connection structure between the elastic pieces and the slider generally have problems such as overly complex structure, inconvenient installation, and low production efficiency. These problems not only increase the production cost, but also affect the overall use effect of the slider.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to ordinary technical personnel in this field. Utility Model Content

[0005] In order to solve the problems that currently on the market, the elastic pieces and the connection structure between the elastic pieces and the slider generally have problems such as overly complex structure, inconvenient installation, and low production efficiency. These problems not only increase the production cost, but also affect the overall use effect of the slider, this application provides a durable zipper that prevents edge warping.

[0006] The durable zipper that prevents edge warping provided by this application adopts the following technical solutions:

[0007] A durable zipper that prevents edge warping, including a zipper head body. Two fixing blocks are fixed on the top of the zipper head body. A limiting rod is fixedly connected between the two fixing blocks. A connecting ring is sleeved on the zipper head body through the limiting rod. A first connecting ring is also sleeved on the connecting ring. A second connecting ring is rotatably connected to one side of the first connecting ring. A pull tab is movably connected to the second connecting ring.

[0008] Preferably, an anti-slip layer is also fixed on the pull tab.

[0009] Preferably, the anti-slip layer is made of silicone material.

[0010] Preferably, the connecting ring is made of metal material.

[0011] Preferably, the limiting rod has a curvature.

[0012] Preferably, a plurality of tiny protrusions are provided on the surface of the anti-slip layer.

[0013] Preferably, the zipper head body is made of high-strength engineering plastic material and is designed through a fine mold and injection molding process.

[0014] In summary, the present application includes the following beneficial technical effects:

[0015] Through the ingenious combination of the limiting rod and the connecting ring, the stable connection between the pull tab and the zipper head body is realized, effectively preventing the edge warping of the pull tab, not only improving the overall aesthetics of the zipper, but also significantly enhancing its durability. Secondly, the convenient design of pull tab replacement enables easy replacement without damaging the entire zipper structure when the pull tab is damaged, thereby improving production efficiency and reducing production costs.

[0020] The following is a further detailed description of the present application in combination with the attached Figure 1 - attached Figure 3 to the present application.

[0021] The present application discloses a durable zipper with an anti-warping edge. Figures 1 - 3 A durable zipper with anti-warping edge includes a zipper head body 1, two fixing blocks 2 are fixed on the top of the zipper head body 1, a limiting rod 3 is fixedly connected between the two fixing blocks 2, a connecting ring 4 is sleeved on the zipper head body 1 through the limiting rod 3, a first connecting ring 7 is also sleeved on the connecting ring 4, a second connecting ring 8 is rotatably connected to one side of the first connecting ring 7, and a pull tab 5 is movably connected to the second connecting ring 8; when in use, firstly, the first connecting ring 7 is sleeved on the connecting ring 4, and then the connecting ring 4 is sleeved on the limiting rod 3, so that the pull tab 5 is sleeved through the connecting ring The ring 4 is connected to the limiting rod 3 and then fixed to the zipper head body 1. Due to the action of the limiting rod 3, the pull tab 5 will not move at will, thereby effectively preventing the pull tab 5 from curling up and improving the overall aesthetics and durability of the zipper. When the pull tab 5 is damaged and needs to be replaced, the user only needs to pry open one end of the connecting ring 4, and the first connecting ring 7 can be moved along the outer wall of the connecting ring 4 to easily remove the pull tab 5. The pull tab 5 can be replaced without destroying the entire zipper structure, which not only improves production efficiency but also reduces production costs.

[0022] Reference Figure 1 A non-slip layer 6 is fixed on the pull tab 5. The non-slip layer 6 is made of silicone material. A plurality of tiny protrusions are provided on the surface of the non-slip layer 6 to increase the friction between the finger and the pull tab (5), making it easier to pull the zipper and less likely to slip.

[0023] Reference Figure 1 The connecting ring 4 is made of metal and is not easy to break.

[0024] Reference Figure 2 The limiting rod 3 has a certain curvature, which facilitates the connection ring 4 to move along the outer wall of the limiting rod 3.

[0025] Reference Figure 1 The zipper head body 1 is made of high-strength engineering plastic material, which has excellent wear resistance, impact resistance and corrosion resistance, ensuring that it is not easily damaged after long-term use. The zipper head body 1 has a streamlined appearance after fine mold design and injection molding process. It is not only beautiful, but also can reduce the resistance that may be generated during use and improve the smoothness of the zipper.

[0026] The implementation principle of the anti-warping durable zipper of the embodiment of the present application is as follows: when in use, firstly, the first connecting ring 7 is put on the connecting ring 4, and then the connecting ring 4 is put on the limiting rod 3, so that the pull tab 5 is connected to the limiting rod 3 through the connecting ring 4, and then fixed to the zipper head body 1. Due to the effect of the limiting rod 3, the pull tab 5 will not move at will, thereby effectively preventing the pull tab 5 from warping, and improving the overall aesthetics and durability of the zipper;

[0027] When the pull tab 5 is damaged and needs to be replaced, the user only needs to break open one end of the connecting ring 4, and the first connecting ring 7 can move along the outer wall of the connecting ring 4, and then the pull tab 5 can be easily removed. There is no need to damage the entire zipper structure, and the pull tab 5 can also be replaced, which not only improves production efficiency but also reduces production costs.
