[0003] Therefore, an anti-misplacement invisible zip fastener is proposed to solve or alleviate the above problems. CONTENT OF THE UTILITY MODEL

[0004] The utility model discloses a kind of anti-misplacement invisible zip fasteners to solve the shortcomings existing in prior art.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] An anti-misplacement invisible zip fastener, including chain belt and puller, the two sides of the puller are fixedly connected with pressing plate, the pressing plate is attached to the outer side of chain belt, the chain belt includes stiff thread, the length direction of stiff thread is same with the length direction of chain belt.

[0007] Preferably, the number of pressing plate on any side of the puller is two, the distance between the two ends of the two pressing plates on the same side of the puller is greater than the length of the puller.

[0008] Preferably, a ball is fixedly connected on the pressing plate, and the ball penetrates the pressing plate.

[0009] Preferably, the ball is made of magnetic material, and there are magnetic particles linearly arrayed along the length direction of the chain belt on the chain belt, and the magnetic particles are located on the side away from the puller.

[0010] Preferably, the chain belt further includes wear-resistant yarn, the wear-resistant yarn is perpendicular to stiff thread, and the wear-resistant yarn forms a floating thread on the side of the chain belt close to the pressing plate.

[0012] The utility model has the following beneficial effects:

[0013] This invention uses stiff yarn as warp yarn, which gives the chain belt better stiffness. As the pull head moves along the chain belt, the pressure plate flattens the chain belt below it, while the surrounding chain belt remains flat due to the stiffness of the chain belt itself, thus preventing misalignment of the chain teeth. The stiff yarn is made of three strands of polyester fiber bundles twisted together, and the polyester fiber bundles have good stiffness. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] 1. Chain belt; 2. Slider head; 3. Pressure plate; 4. Beads; 5. Magnetic particles. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] A type of anti-misalignment invisible zipper, such as Figure 1 As shown, the device includes a chain belt 1 and a slider 2. Pressure plates 3 are fixedly connected to both sides of the slider 2, and the pressure plates 3 fit against the outer surface of the chain belt 1. The chain belt 1 includes stiffening yarn, the length direction of which is the same as the length direction of the chain belt 1. There are two pressure plates 3 on each side of the slider 2, and the distance between the ends of the two pressure plates 3 on the same side of the slider 2 is greater than the length of the slider 2. Specifically, the pressure plates 3 and the slider 2 are integrally formed. Both chain belts 1 are made using a warp and weft weaving method. By using stiffening yarn as the warp yarn, the chain belt 1 has… It has good stiffness. As the slider 2 moves along the chain 1, the pressure plate 3 flattens the chain 1 below it, while the surrounding chain 1 remains flat due to the stiffness of the chain 1 itself, preventing the chain teeth on the chain 1 from misaligning. Two pressure plates 3 are fixedly connected to both sides of the slider 2. The four pressure plates 3 are combined in an X shape, which increases the range of influence of the pressure plates 3 on the chain 1, ensuring that no matter whether the slider 2 moves forward or backward along the chain 1, the section of the chain 1 that the slider 2 is about to pass through in the forward direction can be flattened by the pressure plate 3.

[0018] like Figure 1As shown, a bead 4 is fixedly connected to the pressure plate 3, and the bead 4 passes through the pressure plate 3. The bead 4 is made of magnetic material. Magnetic particles 5 are linearly arrayed along the length of the chain belt 1. The magnetic particles 5 are located on the side of the bead 4 away from the slider 2. Specifically, each pressure plate 3 is inlaid with a bead 4. The raised bead 4 will increase the pressure of the pressure plate 3 on the chain belt 1. The magnetic particles 5 are adhered to the surface of the chain belt 1. When the slider 2 is pulled to make the chain teeth on the two chain belts 1 mesh, the magnetic particles 5 on both sides of the slider 2 are attracted by the bead 4, that is, the magnetic particles 5 move closer to the slider 2, thereby making the two chain belts 1 move closer to each other, making the movement of the slider 2 smoother. At the same time, the radius of the bead 4 is larger than the thickness of the magnetic particles 5 to prevent the pressure plate 3 from scraping off the magnetic particles 5.

[0019] like Figure 1 As shown, the chain belt 1 also includes abrasion-resistant yarn, which is perpendicular to the stiffening yarn. The abrasion-resistant yarn forms a floating long yarn on the side of the chain belt 1 near the pressure plate 3. The abrasion-resistant yarn is made of nylon fiber bundles twisted together, and the stiffening yarn is made of polyester fiber bundles twisted together. Specifically, the abrasion-resistant yarn is made of three strands of nylon fiber bundles twisted together. The chain belt 1 uses the abrasion-resistant yarn as the weft yarn and the stiffening yarn for warp and weft weaving, forming a five-end three-fly weft satin weave. The floating long yarn formed by the abrasion-resistant yarn, combined with the good abrasion resistance of the nylon fiber bundles, improves the abrasion resistance of the surface of the chain belt 1. The stiffening yarn is made of three strands of polyester fiber bundles twisted together, and the polyester fiber bundles have good stiffness.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
