Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of zipper structures, and in particular to a zipper structure with a built-in elastic element. Background Art
[0002] Zippers, as a common connector, are widely used in clothing, luggage, tents, and many other fields, bringing great convenience to people's lives. The traditional zipper structure mainly consists of two cloth straps, chain teeth, and a slider. The slider slides over the chain teeth to open and close the zipper.
[0003] Traditional zippers lack effective tension adjustment. Different users have varying needs for zipper tightness. Some prefer a tight fit for a better seal, while others prefer a looser fit for greater comfort. However, traditional zippers cannot meet these personalized needs. Once installed, the tightness is fixed, making it difficult to adjust.
[0004] Traditional zippers also present difficulties in repair and replacement. When a zipper malfunctions, such as a damaged tooth or a stuck slider, it's difficult to repair or replace the zipper individually due to its structural design. This typically requires removing the entire zipper from the item, a complex process that can easily damage other parts of the item. Summary of the Invention

[0041] In this embodiment, during use, the user can adjust the height of the elastic pressure frame 5 by toggling the outer plate 64, thereby adjusting the tightness of the zipper. To tighten the zipper, the outer plate 64 is toggled, causing the support column 631 to move, releasing its support from the elastic curved plate 61. The elastic curved plate 61 bends downward, driving the elastic pressure frame 5 downward via the connecting belt 62, increasing the pressure on the zipper teeth. To loosen the zipper, the outer plate 64 is toggled in the opposite direction, causing the support column 631 to move, supporting the elastic curved plate 61. This compresses the elastic curved plate 61, driving the elastic pressure frame 5 upward via the connecting belt 62, reducing the pressure on the zipper teeth. Further compression of the elastic curved plate 61 releases the first locking member 3 or the second locking member 4 from the zipper teeth, allowing the zipper to be freely opened.
[0042] The above are preferred embodiments of the present invention. Those skilled in the art to which the present invention belongs can also change and modify the above embodiments. Therefore, the present invention is not limited to the above specific embodiments. Any obvious improvements, replacements or modifications made by those skilled in the art on the basis of the present invention fall within the scope of protection of the present invention.
