Fastening apparatus for preventing shoelace from loosening

Abstract

A purpose of the present invention is to provide a fastening apparatus, wherein the fastening apparatus has elasticity, can be fixed on the surface of a shoe tongue, can ensure that a shoelace is not easily loosened after the shoelace is fastened, can ensure that the shoelace is not blocked when the shoelace is loosened so as to smoothly loosen, and can prevent the shoelace from loosening. The fastening apparatus comprises: a base arranged above the shoe tongue cover sheet surface; a shoelace fastening fixation seat, wherein the shoelace fastening fixation seat and the base are subjected to integrated molding, the shoelace fastening fixation seat is provided with a transverse-penetrating first through hole for passing-through of the shoelace and is provided with a longitudinal-penetrating accommodating groove, and an upwardly-projecting first positioning projection block is arranged on the center of the bottom surface of the accommodating groove; a pressing column arranged inside the accommodating groove, wherein the pressing column is provided with a transverse-penetrating second through hole for passing-through of the shoelace, the corresponding directions of the transverse-penetrating second through hole and the first through hole are the same, a downwardly-projecting second positioning projection block is arranged on the bottom end of the pressing column and is longitudinally corresponding to the first positioning projection block, and an inverse-cone-like projecting baffle block is arranged on the bottom edge of the outer side of the pressing column; and an elastic assembly arranged in the accommodating groove between the pressing column and the shoelace fastening fixation seat.

Description

technical field [0001] The invention relates to a fastening device, in particular to a fastening device for fixing the tether on the surface of the shoe tongue and preventing the shoe tether from loosening. Background technique [0002] Generally, the shoelaces on the shoes often have troubles of loosening. The most common way to tie the shoelaces is to tie a bowknot at the end of the shoelaces to facilitate taking off and putting on the shoes. The shoelaces are loosened due to jumping and other reasons, and the shoelaces are often untied, which often has to be tied again. When putting on or taking off the shoes, they have to be tied or loosened again, which is very inconvenient; It is common for the shoelaces of the bow to come loose. [0003] Therefore, in view of the above-mentioned situation, some practitioners proposed that as shown in Patent Document 1, it is a belt buckle for positioning a belt, including: a buckle body with a top surface and a bottom surface opposit...

Problems solved by technology

[0004] However, in the belt buckle mentioned above, since the buckle body is not fixed on the surface of the shoe tongue, when the user performs strenuous exercise, the buckle body is likely to swing and drag on the ground due to violent shaking. Then cause the buckle or belt body to be stepped on by oneself or by others, resulting in fall and injury. In addition, the buckle body does not have elasticity, so when running fast on the court or high jumping for the ball, if it is stepped on by others , it is easy to cause pain or injury on the back of the foot, so it is really necessary to improve
