Description

The present invention relates to a strapping technique, and more particularly to a high-strength assembled strapping structure.

Conventionally, laces have been widely applied to various daily clothes, bags, string strings and the like. For example, a strap is generally provided on a string of a mobile phone. Both ends of the threaded string are tied with a half knot, a figure eight knot, a main knot, a moist knot, a wound knot, etc. to form a loop, but since the knot is exposed in such a string fastening structure, the knot is exposed. There was a drawback that the appearance was not very good. Further, in the prior art, there was a cord stopper in which the end of the string is housed in the engaging case, but it has perforations formed at the upper and lower ends of the engaging case and ties both ends of the string to form a knot. After that, the knot has a structure hidden in the engagement case, but the position of the knot and the engagement case constrains the through cord to be inserted into the upper and lower perforations of the engagement case and has an upper loop and a lower loop. A stringing structure was formed. However, such a conventional string-fixing structure has a high difficulty of mold opening, a high manufacturing cost, a low production efficiency, there is a problem that it is not easy to assemble, and a human cost is also high. there were.

Therefore, an object of the present invention is to prevent the engaging case from receiving the pulling force of the through cord, and even if the pulling force received by the cord body is large, it is hard to cut, and the appearance is excellent, and the high-strength assembled cord stopper is provided. To provide the structure.

Therefore, the present inventor has conducted extensive studies in order to solve the above-mentioned problems of the present invention, and as a result, as described later, at least both ends of the through cord have a string knot formed, and the string knot is formed inside the engaging case.

Hereinafter, the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the drawings.

Please refer to FIG. 1 to FIG. As shown in FIGS. 1 to 3, the high-strength assembled cord fastening structure according to one embodiment of the present invention comprises at least a through cord 3 and an engagement case 1. A string knot 33 is formed at both ends of the thread string 3. A storage chamber 10 is formed inside the engagement case 1. A string passage hole 13 is formed in the bottom or side of the storage chamber 10. The string passing hole 13 is penetrated inside and outside. A storage port 11 is formed at the top of the engagement case 1. The storage port 11 is provided with a knot position restricting portion. The string knot 33 is fitted into the storage chamber 10. The string knot 33 and the inside of the knot position restraint are positionally restrained, and the string knot 33 is used as a stopper. The upper portion of the through string 3 is inserted into the storage port 11 and extends above the knot position restraint portion of the engagement case 1 to form an upper loop 31. The lower portion of the threaded string 3 is inserted into the threaded hole 13 and extends to the outside of the engagement case 1 to form a lower loop 32. The engaging case is used as a stopper, and an upper loop 31 for hooking a support is formed on the upper portion of the through cord 3. A lower loop 32 for hanging the ornament is formed on the lower portion of the string 3. The pulling force received by the stringing structure is entirely received by the loop formed by binding, and the engaging case structure has an advantage that it has high strength and good appearance in addition to receiving the pulling force. In addition, the structure of the engaging case structure is simple, and the two combined parts of the engaging case structure are mainly configured by an engaging case body having a hollow inside, and the engaging case body is integrally molded to open the mold. Low difficulty and low manufacturing cost. The thread string 3 of this embodiment is made of a replaceable member, and the user can use thread strings having different thicknesses and different lengths as the thread string 3, which is practical.

Suitably, the number of the string passing holes 13 may be two. As shown in FIG. 4, two string through holes 13 are formed in the bottom portion of the engagement case 1 having the string fastening structure. The two string passing holes 13 are formed at intervals, and the string passing holes 13 are vertically penetrated through the bottom of the engagement case 1. The threaded strings 3 on both sides of the lower part of the threaded string 3 are respectively inserted into the two threaded holes 13. The advantage of such a structure is that the diameter of the string passing hole 13 is small, the distance between the passing string 3 and the string passing hole 13 is small, and the appearance is good. Since the swing width generated between the engaging case 1 and the engaging case 1 is small, it is possible to prevent the threaded cords 3 on both sides in the engaging case 1 from being entangled. The engagement case 1 has a cylindrical shape, but may be a truncated cone, a barrel shape, or another polygonal pillar shape, or another deformed body.

Specifically, the knot position restraint part may be an integrally molded concentrated structure or a drop seal structure. In a preferred method, the knot position restraint part is molded into a top cover structure, and the top cover structure has a shape and size with a storage port.
