Embodiment 1

[0030] like figure 1 As shown, the imitation dragonfly Velcro hook sheet provided by the embodiment of the present invention includes a strap 1, and one side of the strap 1 is provided with a plurality of pestle-shaped Velcro 2 made of plastic material, and the pestle-shaped The hook and loop fastener 2 includes a stem part 21 and a head part 22 of an integral structure. The rod portion 21 is cylindrical and the rod portion 21 is arranged perpendicular to the plane of the belt or at an oblique angle to the plane of the belt, and the lower end of the rod 21 is fixed on the belt 1 . The head 22 is approximately spherical in shape with a diameter larger than the cross-sectional diameter of the rod 21 , and the head 22 is tightly connected to the upper end of the rod 21 .

[0031] It should be noted that the head 22 is in a closed and roughly spherical shape, specifically, it can be an egg-shaped, light bulb-shaped or other similar closed and streamlined structure with a wider en...

Embodiment 2

[0050] The present invention also provides a dragonfly-like hook and loop fastener, which includes the hook piece of the dragonfly-like hook and loop fastener described in Embodiment 1 and the fur piece matched with the hook piece.

[0051] Provide the specific application test embodiment of several imitation dragonfly hook and loop fasteners of the present invention below:

[0052] The hook piece of the imitation dragonfly Velcro used in this test example is consistent with that in the specific application test of Example 1.

[0053] After testing, the tangential tensile force of the imitation dragonfly hook and loop in this test example can reach 22N / cm 2 , the maximum peeling force does not change much after 30,000 times of use, the maximum peeling force for the first time is about 1.6N / cm, and the maximum peeling force for the 30,000th time is about 1.6N / cm.

[0054] After testing, the average volume of the noise produced by the dragonfly-like hook and loop fastener when ...

Abstract

The invention relates to the technical field of sticking bands, in particular to an imitated dragonfly sticking band hook sheet and an imitated dragonfly sticking band. One surface of the imitated dragonfly sticking band hook sheet is provided with multiple pestle-shaped sticking fasteners made from a plastic material, each pestle-shaped sticking fastener comprises a rod part and a head part which are of an integral structure, the rod part is in a column shape and is vertical to a band sheet plane or is arranged at an inclined angle with the band sheet plane, the lower end of the rod part is fixed to a band sheet, the head part is in a sealed rough sphere shape and the sphere diameter is larger than the cross section diameter of the rod part, and the head part is closely connected to the upper end of the rod part. Through the imitated dragonfly sticking band hook sheet and the imitated dragonfly sticking band, the problems that existing Nylon sticking fastener bands are poor in durability and big in noise when in use, easily hook sweaters and the like to make the sweaters fluff, and make the skin easily generate pricking when the Nylon sticking fastener bands make direct contact with the skin.

Description

technical field [0001] The invention relates to the field of Velcro technology, in particular to a dragonfly imitation Velcro hook piece and a dragonfly imitation Velcro. Background technique [0002] Since people invented Velcro fasteners inspired by the hook structure of burdock fruit, Velcro fasteners have been widely used in various fields, such as clothes, windows, game appliances, medical bandages, etc., and have also been used in tribological research in recent years. [0003] However, problems such as the poor durability of the nylon hook and loop fastener, loud noise (about 75dB), easy hooking on sweaters, etc. to make it fluff, and easy to produce tingling sensation when directly touching the skin have also plagued users. [0004] Velcro is composed of hook piece and wool piece, the tangential pulling force is about 15N / cm 2 . Although by increasing the number of hooks at the top of the rod, the adhesive force of the velcro can be increased, and to a certain exte...
