Description

Technical Field

[0001] The utility model relates to a protective buckle, in particular to a shoe webbing protective buckle. Background Art

[0002] Shoes with laces, usually these shoes are equipped with perforations for the laces to be passed through. In the past, there were metal rings set like rivets on the perforations, and later there appeared lace holes sewn directly on the vamp with ribbons.

[0003] Because the metal ring damages the surface of the shoe, after wearing this type of shoes for a long time, the upper fibers that are bitten by the outer periphery of the metal ring will be damaged every time the shoelaces are tightened, and this type of shoes is gradually being eliminated from the market.

[0004] Then there came shoes that used webbing directly. Because the shoelaces often rubbed against the webbing, over time, the edges of the webbing became fuzzy, damaged, or even broken. This is also an objective problem that currently exists in this type of shoes. Summary of the invention

[0005] The utility model aims to provide a shoe webbing protective buckle which can reduce the friction between shoelaces and webbing and increase the service life of webbing.

[0006] The technical solution to the problem to be solved by the utility model is as follows:

[0007] A shoe webbing protective buckle, characterized in that it comprises a head portion for shoelaces to pass through, and a trunk portion for the webbing to be wrapped and sewn to strengthen the tensile resistance and wear resistance of the webbing surface; wherein the head portion for the shoelaces to pass through is a perforation, and the perforation has at least one arcuate surface in contact with the shoelaces; the trunk portion extends from the other end of the head perforation away from the arcuate surface in contact with the shoelaces, and has a wider side in contact with the webbing.

[0008] Preferably, at the other end of the arcuate surface of the perforation away from the shoelace contacting area is a convergence area formed by two surfaces at an acute angle, and the convergence area and the arcuate surface make the cross section of the perforation present a teardrop shape.

[0009] Preferably, the head also has a guide limiting groove, and the guide limiting groove is arranged on both sides of the through hole.

[0010] Preferably, there are two perforations, which are stacked up and down on the side of the head.

[0011] Preferably, the side surface of the trunk portion is provided with a thread hole for the weaving thread to pass through.

[0012] Beneficial effects of the utility model

[0013] Compared with the prior art, the utility model achieves the purpose of prolonging the service life of shoelaces and webbing by adding a protective buckle with a low friction coefficient between the webbing and the shoelaces, so that the friction between the two is completely isolated. In addition, because the structure of the head and trunk of the protective buckle is combined with the webbing, the webbing fibers are not pulled and undergo major changes during the shoelace tying process. In addition, the protective buckle is wrapped and sewn to form the skeleton of the webbing, which shapes the webbing and indirectly improves the grade of the shoes using the protective buckle.

[0018] The following will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, that is, a large number of specific details are given to provide a more thorough understanding of the present invention. However, for those skilled in the art, the present invention can be implemented without one or more of these details. In these examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0019] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. Therefore, they are only used as examples and cannot be used to limit the scope of protection of the present invention.

[0020] In addition, it should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0021] This shoe webbing protection buckle is uniquely designed. First, it includes a head 1 for shoelaces to pass through, and the uniqueness of the perforation 11 is that it has at least one arc surface 12 that is in close contact with the shoelaces. This design allows the shoelaces to pass through the perforation 11 smoothly. In addition, it also includes a trunk part 2 for the webbing 3 to be wrapped and sutured to strengthen the tensile resistance and wear resistance of the webbing 3.

[0022] The head 1 has a through hole 11 for shoelaces to pass through, and the through hole 11 has at least one arc surface 12 in contact with the shoelaces; the torso portion 2 extends from the other end of the through hole 11 in the head 1 away from the arc surface 12 in contact with the shoelaces, and has a wider side 21 in contact with the ribbon 3.

[0023] During implementation, the protective buckle can be formed by plastic injection molding.

[0024] The trunk part 2 of this protective buckle is also one of its design highlights. It extends from the other end of the head perforation 11 away from the curved surface, with smooth lines and beautiful shapes. The side width of the trunk part 2 is moderate and in contact with the webbing, which can enhance the tensile strength of the webbing while reducing the wear of the webbing 3 and extending the service life of the webbing 3.

[0025] In general, the design of this shoe webbing protection buckle is ingenious, taking into full consideration the perforation requirements and tensile properties of the webbing, so that it not only ensures the service life of the webbing, but also gives the shoes a unique aesthetic effect. Whether from a practical or aesthetic point of view, this protection buckle is an excellent product.

[0026] Furthermore, as an improvement to the present invention, at the other end of the arc surface 12 of the perforation 11 away from the shoelace contact, there is a convergence area formed by two surfaces at an acute angle, and the convergence area and the arc surface 12 make the cross-section of the perforation 11 teardrop-shaped.

[0027] This design makes the area below the perforation 11 smaller, making it easier for the protective buckle to be placed on the relatively narrow webbing 3 and wrapped and sewed with thread.

[0028] Furthermore, as an improvement to the present invention, the head 1 also has a guide limit groove 13 , and the guide limit groove 13 is arranged on both sides of the through hole 11 .

[0029] During implementation, the guide limiting groove 13 can facilitate the wrapping of the webbing 3 , and the corresponding portion can be concavely limited in the guide limiting groove ring 13 .

[0030] Furthermore, as an improvement to the present invention, there are two through holes 11 , and the two through holes 11 are stacked up and down on the side of the head 1 .

[0031] During implementation, the upper and lower through holes 11 can be used for the shoelace to be passed through and the shoelace to be passed back through respectively.

[0032] Furthermore, as an improvement to the present invention, the side surface of the trunk portion 2 is provided with thread holes for the weaving threads to pass through (not shown in the figure).

[0033] During implementation, if the material of the protective buckle is thicker, a thread hole can be provided to facilitate the passage of the thread so that the protective buckle is wrapped by the webbing.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
