Fastening device

Abstract

A fastening device can be attached to an activity equipment. The fastening device includes at least one buckle and a flexible band. At least one positioning pillar is provided inside the buckle. The flexible band has two end portions, and each end portion has at least one positioning hole. The buckle and the flexible band can be assembled together and separated from each other. In an assembled state, the positioning pillar inserts inside the positioning hole so that the end portion is fixed inside the buckle and the flexible band extends outside the buckle from a rear end of the buckle.

What is claimed is: 
     
         1 . A fastening device, being configured to be attached to an activity equipment, and the fastening device comprising two opposing portions, at least one of which is detachable from the activity equipment and includes:
 a buckle, comprising at least one positioning pillar; and   a flexible band, comprising an end portion, which is provided with at least one positioning hole;   wherein the buckle and the flexible band is configured to be assembled together or detached from each other, and in an assembled state, the at least one positioning pillar respectively inserts inside the at least one positioning hole, whereby the flexible band is fixed within the buckle at the end portion thereof.   
     
     
         2 . The fastening device of  claim 1 , wherein each of the two opposing portions is detachable from the activity equipment. 
     
     
         3 . The fastening device of  claim 2 , wherein the buckle comprises a body and a cover, wherein the cover is covered on an accommodating base of the body so that the end portion of the flexible band is clamped between the cover and the accommodating base. 
     
     
         4 . The fastening device of  claim 3 , wherein the at least one positioning pillar is formed on a bottom surface of the accommodating base. 
     
     
         5 . The fastening device of  claim 3 , wherein the accommodating base is further provided with two first limiting bumps which are symmetrical and apart from each other by a first spacing, the first spacing is substantially smaller than an outer diameter of the flexible band; the cover has a rear end being provided with a guide channel, and when the cover is covered on the accommodating base, the guide channel is formed between the two first limiting bumps, thereby forming an insertion opening at a rear end of the buckle for guiding the flexible band to extend outward from the buckle. 
     
     
         6 . The fastening device of  claim 4 , wherein the accommodating base further comprises two second limiting bumps which are symmetrical and formed on the bottom surface of the accommodating base with a second spacing therebetween, and the at least one positioning pillar is located between the two second limiting bumps, wherein the second spacing is substantially smaller than an outer diameter of the flexible band. 
     
     
         7 . The fastening device of  claim 5 , wherein the cover has an inner surface comprising two first protrusions and a second protrusion, the two first protrusions are symmetrical and separately arranged, and when the cover is covered on the accommodating base, the end portion of the flexible band is adapted to be located between the two first protrusions, and the second protrusion is pressed against the end portion, wherein the two first protrusions are proximal to the rear end of the cover, and the second protrusion is distal from the rear end of the cover. 
     
     
         8 . The fastening device of  claim 3 , wherein the buckle has a front end which is configured to be attached to a buckling device of the activity equipment, and wherein the front end of the buckle forms a buckling portion extending from the accommodating base. 
     
     
         9 . The fastening device of  claim 5 , wherein each of the first limiting bumps has a surface facing the at least one positioning pillar, the surface is formed with a first mortise, and the cover has two first tendons which are buckled together with the first mortises respectively. 
     
     
         10 . The fastening device of  claim 8 , wherein a second mortise is centrally formed at an interface between the accommodating base and the buckling portion, and the cover has a second tendon which is correspondingly buckled with the second mortise. 
     
     
         11 . The fastening device of  claim 2 , wherein the flexible band is one of a solid tube or a hollow tube, wherein the flexible band is provided with a plurality of positioning holes which are equidistantly arranged along an axial direction of the flexible band. 
     
     
         12 . The fastening device of  claim 11 , wherein the plurality of positioning holes are at least partially formed all way through the flexible band in a radial direction of the flexible band. 
     
     
         13 . A fastening device, being configured to be attached to an activity equipment, and the fastening device comprising two opposing portions, one of which extends from the activity equipment, and the other includes:
 a buckle, comprising at least one positioning pillar; and   a flexible band, comprising an end portion, which is provided with at least one positioning hole;   wherein the buckle and the flexible band is configured to be assembled together or detached from each other, and in an assembled state, the at least one positioning pillar respectively inserts inside the at least one positioning hole, whereby the flexible band is fixed within the buckle at the end portion thereof.
