Embodiment Construction

[0024] will now refer to Figure 2-4 The elongating hook structure of the Velcro tape of the present invention and the Velcro fastening tape including the elongating hook structure will be described in detail.

[0025] figure 2 It is a schematic plan view of an injection hook structure of a Velcro fastener according to an embodiment of the present invention. As shown in the figure, the Velcro injection hook 10 of the present invention includes a hook body 11, which has a bottom 12 integrally formed with the Velcro substrate 8, a crotch 13 and a hook corresponding to the crotch 13 Body side curve 14 . The hook 13 includes a hook end 15 and a neck 16 between the hook body 11 and the hook end 15 . The neck 16 has a curved portion 17 opposite to the side bend 14 of the hook body.

[0026] The curved arc of the hook body side curved portion 14 is determined by a partial circumference of a first circle C1 with a radius R1, wherein the center C of the first circle C1 is a distanc...

Abstract

The invention provides a novel jet hook structure of a velcro tape and a velcro tape containing the same. An innovative design is performed against the interrelation among the curvature radian of a hook body of a jet hook, the neck part of the curved hook part and the tail end of the hook so as to prevent the occurrence of problems of stress concentration of the jet hook, plastic deformation of the jet hook, damages of the jet hook and a pile loop and the like, thereby achieving the effects of prolonging the effective service life of the jet hook and the pile loop, prolonging the hook joint between the jet hook and the pile loop, enhancing the adhesive strength between the jet hook and the pile loop and the like.

Description

technical field [0001] The present invention relates to an injection hook structure of a Velcro tape and a Velcro tape with the structure of the Velcro hook. Background technique [0002] The traditional Velcro, commonly known as 'Velcro Felt', is widely used in applications that require two separate parts to be releasably bonded, such as in garments, due to its easy felting and separation properties. , shoe materials, personal hygiene products (such as paper diapers) and other related applications. Recently, the Velcro-related market has been gradually replaced by the Velcro with the injection hook type. Compared with the traditional Velcro, the Velcro with the Injection hook is lighter, thinner and stronger. Horizontal tensile force, peeling force, and it is not easy to reduce the appearance and texture of the finished product due to the negligence in the process of processing, and the appearance and texture of the finished product are not easy to be reduced. In addition...
