Technical Field

[0001] The utility model relates to the technical field of zipper structures, in particular to a novel double-layer zipper head structure and a zipper. Background Art

[0002] With the development of human society, economy, science and technology, zippers have undergone a long evolution, evolving from metal to non-metallic materials, from a single type and single function to multiple types, specifications and integrated functions, and from simple construction to today's exquisite, beautiful and colorful ones. Their performance, structure and materials are constantly changing, and their applications are wide-ranging, penetrating into various fields such as aerospace, aviation, military, medical and civilian use. The role of the small zipper in people's lives is becoming increasingly important, and its importance and vitality are becoming increasingly evident.

[0003] As people's living standards improve, their demands for daily necessities are also becoming increasingly demanding. Zippers are known for their ease of use, freedom of movement, and the ability to repeatedly open and close them. Zippers, consisting of two flexible, interlocking teeth, are a common connector. As an auxiliary item, they are widely used in clothing, luggage, and other daily necessities. With the advancement of science and technology, the zipper's materials have been continuously expanded, and its shape has also been changed.

[0004] When used in bags, the zipper is prone to bursting due to excessive loading. Therefore, improving the zipper locking strength to reduce the zipper bursting due to excessive loading has become a problem that needs to be solved urgently by those skilled in the art.

[0005] Moreover, when the existing luggage zipper is at a corner position, the curvature of the zipper under the zipper head is relatively large, the bite force is stronger, the pulling and closing resistance is relatively large, and it is relatively inconvenient to use.

[0006] There is a need for a novel zipper slider structure and zipper that can solve the above-mentioned problems. Utility Model Content

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A novel double-layer zipper head structure includes an upper slide plate and a lower slide plate. The bottom surface of the upper slide plate is connected to the lower slide plate through a guide column, and the bottom surface contour area of the lower slide plate is smaller than the bottom surface contour area of the upper slide plate.

[0010] Preferably, symmetrical upper side plates are provided on both sides of the upper slide along the pulling direction of the slider, and symmetrical lower side plates are provided on both sides of the lower slide along the pulling direction of the slider.

[0011] Preferably, the outer end of the branch guide column is recessed inwardly and provided with an arc-shaped surface connected to the lower slide plate at the bottom.

[0012] Preferably, the connection between the bottom surface of the lower slide plate and the branch guide pillars is provided with an inwardly concave arc profile from the middle to the connection on both sides.

[0013] Preferably, an upper pressure tooth groove is provided in the middle position of the bottom surface of the upper slide plate, and the upper pressure tooth groove is continuously provided with the branch guide column. A lower pressure tooth groove is provided in the middle position of the lower surface of the sliding slide plate, and the lower pressure tooth groove is continuously provided with the branch guide column.

[0014] A zipper includes a first cloth tape and a second cloth tape located behind the first cloth tape, wherein a double-layer chain tooth structure is installed on the upper side of the first cloth tape and the second cloth tape, a spacer cloth layer is arranged in the middle of the double-layer chain tooth structure, and the double-layer chain tooth structure is pulled together by the above-mentioned zipper head.

[0015] The beneficial effects of the present invention are:

[0016] The utility model is provided with a double-layer zipper structure, which has higher locking strength, prevents the zipper from being burst due to too many items being placed in the bag, has a longer service life, and greatly improves safety.

[0017] The utility model sets the contour area of the lower slide plate to be smaller than that of the upper slide plate. When the zipper is opened and closed, the curvature of the lower zipper is greatly reduced, so that the opening and closing resistance is smaller, the opening and closing is easier and more labor-saving, and the use is more convenient.

DETAILED DESCRIPTION

[0023] The specific contents of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0024] See also Figure 1-4 As shown, the utility model provides a new double-layer zipper head structure, including an upper slide plate 1 and a lower slide plate 3. The bottom surface of the upper slide plate 1 is connected to the lower slide plate 3 through a guide column 2, and the bottom surface contour area of the lower slide plate 3 is smaller than the bottom surface contour area of the upper slide plate 1.

[0025] A zipper includes a first fabric tape 4 and a second fabric tape 5 positioned behind the first fabric tape 4. A double-layered tooth structure 6 is mounted on the upper side of each of the first and second fabric tapes 4 and 5. A spacer fabric layer 61 is disposed between the double-layered tooth structure 6. The double-layered tooth structure 6 is drawn and closed by the zipper head. The double-layered tooth structure 6 includes upper-layered tooth elements 62 and lower-layered tooth elements 63. A zipper channel is formed between the upper and lower slide plates 1 and 3, through which the upper and lower teeth 62 and 63 are drawn and closed.

[0026] Furthermore, a mounting bracket 13 for mounting a pull tab is provided on the upper surface of the upper slide plate 1 .

[0027] Furthermore, to prevent the zipper teeth from detaching from the zipper head and to guide the zipper so that the zipper teeth are closed, symmetrical upper side plates 11 are provided on both sides of the upper slide plate 1 along the direction in which the slider is pulled, and symmetrical lower side plates 31 are provided on both sides of the lower slide plate 3 along the direction in which the slider is pulled. The upper side plates 11 and lower side plates 31 close the zipper teeth on the upper and lower sides and protect the teeth.

[0028] Furthermore, in order to make the zipper enter the zipper head more smoothly and use it more labor-saving, the outer end of the sub-guide column 2 is recessed inward and provided with an arc-shaped surface 32 connected to the lower slide plate 3 at the bottom.

[0029] Furthermore, the connection between the bottom surface of the lower slide plate 3 and the sub-guide pillars 2 is provided with an inwardly concave arc profile from the middle to the connection on both sides.

[0030] Furthermore, an upper pressing tooth groove 12 is provided in the middle of the bottom surface of the upper slide plate 1, and is continuous with the sub-guide post 2. A lower pressing tooth groove 33 is provided in the middle of the upper surface of the lower slide plate 3, and is continuous with the sub-guide post 2. When the zipper is closed, the upper pressing tooth groove 12 and the lower pressing tooth groove 33 squeeze the zipper teeth to close the zipper, making the zipper lock tighter.

[0031] This embodiment is provided with a double-layer zipper structure, which has higher locking strength, prevents the zipper from being burst due to placing too many items in the bag, has a longer service life, and greatly improves safety.

[0032] In this embodiment, the lower slide plate is configured to have a smaller contour area than the upper slide plate. When the zipper is opened and closed, the curvature of the lower zipper is greatly reduced, resulting in smaller closing resistance, easier closing and more labor-saving, and more convenient use.
