AI Technical Summary

Technical Problem

Traditional hook and loop fasteners are prone to deformation or breakage, the fiber layer on the surface is easily worn, and the single-material base layer lacks flexibility and breathability, resulting in unstable fastening effect.

Method used

It adopts a composite base structure, including a flexible support layer and a rigid fixing layer. The hook-face component is set on the rigid fixing layer, and the rough-face component is set on the flexible support layer. The connecting part is equipped with anti-slip protrusions and barbs. The diameter of the root of the connecting carrier is larger than that of the connecting part to increase friction and contact area, combined with a flexible and breathable design.

Benefits of technology

It improves the pull-out resistance of hook and loop fasteners, enhances the firmness between the hook and loop components, increases friction, prevents lateral slippage, improves breathability and flexibility, and extends service life.

Abstract

The utility model relates to a firmly connected magic tape structure, which comprises a composite base layer (1), a hook surface component (2) and a hair surface component (3), the hook surface component (2) is arranged on one side of the composite base layer (1), the hair surface component (3) is arranged on the other side of the composite base layer (1), the hook surface component (2) comprises a connecting carrier (21) and a connecting part (22), the diameter of the root of the connecting carrier (21) is larger than that of the connecting part (22), and the connecting part (22) is connected with the hook surface component (2). An anti-skid bulge (221) is arranged at the end part of the connecting part (22), and an inverted hook (222) for increasing the hooking firmness of the hook surface component (2) and the hair surface component (3) is arranged on the anti-skid bulge (221). According to the design, on one hand, the contact area between the connecting carrier and the composite base layer is increased, and the pull-off resistance is improved; stress can be dispersed, and the risk of root breakage is reduced; and on the other hand, when the hook surface component and the hair surface component are connected, the hook surface component and the hair surface component are adhered more firmly.
