Disposable anti-counterfeiting buckle

Abstract

The present application discloses a disposable anti-counterfeiting buckle, which includes a buckle seat and a buckle strip. The buckle seat includes a base and a one-way buckle. The base has an installation space and an insertion port. The one-way buckle has multiple buckle structures. A bayonet is formed between the multiple buckle structures. When the one-way buckle is subjected to a force in the direction in which the insertion port extends toward the installation space, the multiple buckle structures can undergo elastic deformation so that the ends forming the bayonet move away from each other to expand the bayonet. The buckle strip includes a soft strip and an anti-cracking portion. The anti-cracking portion is provided on the outer surface of at least part of the soft strip. When subjected to external force, the present invention will not deform as a whole and cause anti-counterfeiting cracking, thereby effectively maintaining the anti-counterfeiting function of disposable use. The present invention also maintains a predetermined softness, effectively avoiding scratching or crushing of items.

Description

Technical Field

[0001] The present invention relates to the technical field of anti-counterfeiting buckles, in particular to a disposable anti-counterfeiting buckle. Background Art

[0002] When clothing, shoes, bags and other products are sold, they are usually equipped with anti-counterfeiting buckles. When designing the anti-counterfeiting buckle, a buckle with a trumpet-shaped channel is installed in the base, and the wide mouth of the trumpet-shaped channel faces the insertion port of the base. The buckle piece of the buckle is pushed by the wide mouth of the trumpet-shaped channel toward the narrow mouth, which can expand the narrow mouth of the trumpet-shaped channel within the elastic range. The buckle strip is installed on the base. When in use, the end of the buckle strip away from the base passes through the insertion port and penetrates the trumpet-shaped channel of the buckle and moves a predetermined distance to connect with the base. At the same time, the buckle piece of the buckle abuts the buckle strip. At this time, if the buckle strip is pulled in the opposite direction, the buckle strip is restricted from moving by abutting with the buckle piece. If it is forcibly pulled out, the buckle may be damaged or the buckle strip may be broken, which in turn causes damage to the entire anti-counterfeiting buckle. Therefore, this anti-counterfeiting buckle can only be used once and can play a good anti-counterfeiting and anti-dropping effect.

[0003] Different materials used to make anti-counterfeiting buckles present different problems during use. If a softer material is used overall, by fixing one end of the buckle strip away from the base and pulling the other end of the buckle strip, the buckle strip will be elastically deformed by tension, and the diameter of the buckle strip will be smaller than the diameter of the buckle strip before being deformed. Once the radial dimension of the stretched buckle strip is smaller than the narrow opening of the buckle's trumpet-shaped channel, the buckle strip can be pulled out of the buckle's trumpet-shaped channel by maintaining its deformed state and pulling it in the opposite direction, causing the anti-counterfeiting buckle to lose its anti-counterfeiting effect. If a harder material is used overall, due to its lack of softness, there is a risk of scratching or crushing the product, affecting product quality. Summary of the Invention

[0004] One advantage of the present invention is that it provides a disposable anti-counterfeiting buckle. When subjected to external force, the present invention will not be deformed as a whole to cause anti-counterfeiting cracking, thereby effectively maintaining the anti-counterfeiting function of disposable use.

[0005] One advantage of the present invention is that it provides a disposable anti-counterfeiting buckle that maintains a predetermined softness and effectively avoids scratching or crushing objects.

[0013] According to an embodiment of the present invention, the soft strip is implemented as a soft rubber material, and the hardness of the soft strip is in the range of Shore A30-98 degrees.

[0014] According to one embodiment of the present invention, the anti-cracking part is implemented as a hard rubber material, and the hardness range of the anti-cracking part is Shore D10-90 degrees. The outer surface of the soft strip body fully covers the anti-cracking part by secondary injection molding or coating. When the snap strip is subjected to force in an attempt to be pulled out of the installation space through the insertion port, the radial size of the snap strip remains unchanged, and the snap structure always abuts against the outer periphery of the anti-cracking part to prevent the snap strip from being pulled out of the installation space toward the insertion port.

[0015] According to one embodiment of the present invention, the soft strip body includes a straight insertion portion, an assembly portion and an extension portion, the assembly portion extends between the straight insertion portion and the extension portion, the extension portion is installed on the seat body, the radial cross-sectional dimensions of the straight insertion portion and the extension portion are both larger than the radial cross-sectional dimensions of the assembly portion, the anti-cracking portion is located on the outer peripheral side of the assembly portion, and when the snap strip passes through the bayonet so that at least part of the anti-cracking portion passes through the bayonet, the snap strip is prevented from moving in the opposite direction by the abutment between the anti-cracking portion and the snap structure to be pulled out of the installation space.

The anti-cracking part is formed on the outer peripheral side of the assembly part by secondary injection molding or coating. The buckle strip is connected to the buckle seat in such a way that the anti-cracking part completely passes through the bayonet and the extension part remains inserted into the bayonet. At this time, the buckle seat is restricted by the anti-cracking part and can move back and forth on the outer surface of the extension part relative to the buckle strip.

[0017] According to one embodiment of the present invention, the anti-cracking part is implemented as a hard rubber material, and the hardness range of the anti-cracking part is Shore D10-90 degrees.

When the snap strip extends into the installation space through the insertion port, the snap strip is blocked by the obstruction of the anti-cracking part by the snap structure and is blocked from further moving in the direction in which the anti-cracking part extends toward the snap seat to limit the snap connection position of the snap strip and the snap seat.

[0018] According to one embodiment of the present invention, a limiting portion is formed between the assembly portion and the extension portion, and the radial cross-sectional dimension of the limiting portion is larger than the maximum dimension of the bayonet that is expanded by the elastic deformation of the snap structure. When the snap strip extends into the installation space through the insertion port, the snap strip is blocked by the obstruction of the limiting portion by the snap structure and is prevented from further moving toward the direction in which the anti-cracking portion extends toward the snap seat to limit the snap connection position between the snap strip and the snap seat.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0032] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0033] refer to Figures 1 to 8 A disposable anti-counterfeiting buckle according to a preferred embodiment of the present invention will be described in detail below. The disposable anti-counterfeiting buckle includes a buckle seat 10, and the buckle seat 10 includes a seat body 11 and a one-way buckle 12. The seat body 11 has an installation space 1101 and an insertion port 1102 connected to the installation space 1101.

[0034] The one-way fastener 12 has multiple snap structures 121, which are arranged in a circular pattern and spaced apart, forming a bayonet 1201 between them. The one-way fastener 12 is mounted on the base 11 so that the bayonet 1201 corresponds to the installation space 1101. With the direction from the insertion opening 1102 toward the installation space 1101 as a reference, the snap structures 121 gradually incline toward the center of the installation space 1101. When a force acts on the one-way fastener 12 in the direction from the insertion opening 1102 toward the installation space 1101, the snap structures 121 elastically deform, causing their ends forming the bayonet 1201 to move away from each other, thereby expanding the bayonet 1201.

[0035] refer to Figures 2 to 8 The disposable anti-counterfeiting buckle further includes a snap-on strip 20, which is adapted to the size of the insertion opening 1102. The snap-on strip 20 includes a soft strip body 21 and an anti-cracking portion 22. The soft strip body 21 is formed by extending from the base body 11, and the anti-cracking portion 22 is provided on at least a portion of the outer surface of the soft strip body 21.

[0036] The snap-on strip 20 can extend into the installation space 1101 through the insertion port 1102, penetrate the bayonet port 1201, and remain in contact with the plurality of snap-on structures 121, wherein at least a portion of the anti-cracking portion 22 passes through the bayonet port 1201. When the snap-on strip 20 is subjected to force in an attempt to be withdrawn from the installation space 1101 through the insertion port 1102, the radial cross-sectional dimensions of the anti-cracking portion 22 remain unchanged. The plurality of snap-on structures 121, under the force transmitted by the anti-cracking portion 22, gather their ends near the bayonet port 1201 toward the center of the bayonet port 1201 to be engaged with the circumference of the snap-on strip 20 and abut against the anti-cracking portion 22, thereby preventing the snap-on strip 20 from being withdrawn from the installation space 1101 toward the insertion port 1102, thereby preventing anti-counterfeiting cracking.

[0037] In this design, the snap strip 20 maintains a predetermined degree of softness, effectively preventing scratches or crushing of items. Furthermore, the anti-crack portion 22 enhances the secure connection between the snap strip 20 and the snap base 10. Compared to existing technologies, this effectively prevents overall deformation of the snap strip 20, which could lead to cracking of the connection, thereby maintaining the anti-counterfeiting function of the disposable product. In summary, the coordinated action of the soft strip 21 and the anti-crack portion 22 enhances overall softness while maintaining anti-counterfeiting properties.

[0038] Preferably, the soft strip 21 is implemented as a soft rubber material, which includes but is not limited to silicone, TPU, PVC, SBS, SEBS, PBAT and degradable PBAT modified materials, and the hardness range of the soft strip 21 is Shore A30-98 degrees.

[0039] refer to Figure 2Preferably, the outer surface of the soft strip body 21 completely covers the anti-cracking portion 22 by secondary injection molding or coating to reduce the ability of the snap strip 20 to deform under tension, thereby preventing the snap strip 20 from becoming thinner under tension, which in turn may cause the connection between the snap strip 20 and the snap seat 10 to break. When the snap strip 20 is subjected to force and attempts to be withdrawn from the installation space 1101 through the insertion port 1102, the radial dimension of the snap strip 20 remains unchanged, and the snap structure 121 always abuts against the outer periphery of the anti-cracking portion 22 to prevent the snap strip 20 from being withdrawn from the installation space 1101 toward the insertion port 1102.

[0040] refer to Figure 3 In one embodiment, the anti-cracking portion 22 is injection molded around the outer periphery of the soft strip 21 and extends a predetermined length on the side of the soft strip 21 away from the buckle seat 10, presenting a slender design. The anti-cracking portion 22 has a predetermined bending modulus and is capable of bending and deforming to enhance overall flexibility. This prevents the anti-cracking portion 22 from becoming thinner under tension, thereby preventing the connection between the buckle strip 20 and the buckle seat 10 from being broken. As the buckle strip 20 extends through the insertion opening 1102 into the installation space 1101, the buckle structure 121 always abuts against the outer periphery of the anti-cracking portion 22 to prevent the buckle strip 20 from being withdrawn from the installation space 1101, thereby maintaining the anti-counterfeiting function. When the buckle strip 20 is subjected to a pulling force in the direction toward the insertion port 1102 so as to be pulled out of the installation space 1101, the radial size of the anti-cracking portion 22 remains unchanged, so that the anti-cracking portion 22 can abut against the buckle structure 121 to prevent the buckle strip 20 from being pulled out of the buckle port 1201 as a whole.

[0041] refer to Figures 4 to 8 Preferably, the soft strip body 21 includes a straight insertion portion 211, a mounting portion 212, and an extension portion 213. The mounting portion 212 extends between the straight insertion portion 211 and the extension portion 213, and the extension portion 213 is mounted on the base body 11. The radial cross-sectional dimensions of the straight insertion portion 211 and the extension portion 213 are both larger than the radial cross-sectional dimensions of the mounting portion 212. The anti-cracking portion 22 is located on the outer peripheral side of the mounting portion 212. When the snap strip 20 passes through the bayonet 1201 so that at least a portion of the anti-cracking portion 22 passes through the bayonet 1201, the snap strip 20 is prevented from moving in the opposite direction to be withdrawn from the installation space 1101 due to the abutment between the anti-cracking portion 22 and the snap structure 121.

[0042] refer to Figure 4In one embodiment, the anti-cracking portion 22 is formed on the outer periphery of the assembly portion 212 by secondary injection molding or coating. With reference to the direction in which the snap strip 20 extends through the insertion opening 1102 into the installation space 1101, the radial cross-sectional dimensions of the anti-cracking portion 22 and the assembly portion 212 gradually increase, and the maximum radial cross-sectional dimension of the anti-cracking portion 22 and the assembly portion 212 is greater than the maximum dimension of the snap opening 1201 that is expanded due to the elastic deformation of the snap structure 121. When the snap strip 20 extends through the insertion opening 1102 into the installation space 1101, the snap structure 121 blocks the anti-cracking portion 22 from further movement toward the snap seat 10, thereby limiting the snapping position of the snap strip 20 and the snap seat 10.

[0043] refer to Figure 5 In another embodiment, the anti-cracking portion 22 is formed on the outer periphery of the assembly portion 212 by secondary injection molding or coating. The buckle strip 20 is engaged with the buckle seat 10 in such a manner that the anti-cracking portion 22 completely passes through the bayonet 1201, so that the extension portion 213 remains inserted into the bayonet 1201. At this time, the buckle seat 10 is restrained by the anti-cracking portion 22 and can reciprocate relative to the buckle strip 20 on the outer surface of the extension portion 213.

[0044] Preferably, when the anti-cracking part 22 is formed by secondary injection molding or coating, the anti-cracking part 22 is implemented as a hard rubber material, and the hard rubber material includes but is not limited to PVC, PP, ABS, nylon, PHA, PLA, PBS and PGA, etc., and the hardness range of the anti-cracking part 22 is Shore D10-90 degrees.

[0045] refer to Figure 6 In a preferred embodiment, a limiting portion 214 is formed between the assembly portion 212 and the extension portion 213. The radial cross-sectional dimension of the limiting portion 214 is greater than the maximum dimension of the bayonet 1201 due to the elastic deformation of the snap structure 121. When the snap strip 20 extends into the installation space 1101 through the insertion opening 1102, the snap structure 121 blocks the limiting portion 214 from further movement toward the anti-cracking portion 22 extending toward the snap seat 10, thereby limiting the snap connection position between the snap strip 20 and the snap seat 10.

[0046] refer to Figures 7 and 8, the anti-cracking part 22 is implemented as a hose. The anti-cracking part 22 is consistent in length with the assembly part 212 and is adapted in size. The anti-cracking part 22 and the soft strip body 21 are designed to be separated, and the anti-cracking part 22 can be sleeved on the outer peripheral side of the assembly part 212. Taking the direction in which the buckle strip 20 extends into the installation space 1101 through the insertion port 1102 as a reference, the radial cross-sectional size of the portion of the straight insertion part 211 close to the assembly part 212 gradually increases, and the maximum diameter of the straight insertion part 211 is greater than the inner diameter length of the anti-cracking part 22, the minimum diameter of the straight insertion part 211 is less than the inner diameter length of the anti-cracking part 22, and the diameter of the assembly part 212 is not greater than the inner diameter of the anti-cracking part 22.

[0047] refer to Figure 7 Preferably, the anti-cracking portion 22 is implemented as a hard rubber tube, such as a nylon tube. The hardness of the anti-cracking portion 22 is Shore D10-90 degrees. The inner diameter of the anti-cracking portion 22 is R mm. The maximum diameter of the straight insertion portion 211 is (R + 0.1 * R) - (R + 0.2 * R) mm. The diameter of the limit portion 214 is greater than (R + 0.2 * R) mm.

[0048] Preferably, the inner diameter of the anti-cracking part 22 is 2 mm and the outer diameter is 3 mm, the minimum diameter of the straight insertion part 211 is 1.8 mm, the maximum diameter of the straight insertion part 211 is 2.2-2.4 mm, and the diameter of the limiting part 214 is 3.5 mm.

[0049] During the assembly process of the anti-cracking portion 22 and the soft strip 21, the anti-cracking portion 22 is subjected to a tensile force extending from the straight insertion portion 211 toward the assembly portion 212, passing through the outer peripheral side of the straight insertion portion 211, which has become thinner due to the applied tensile force. When the soft strip 21 is subjected to force and attempts to be withdrawn from the installation space 1101 through the insertion port 1102, the anti-cracking portion 22 maintains its radial dimensions. When the soft strip 21 becomes thinner due to the tensile force, the anti-cracking portion 22 abuts against the snap structure 121 to prevent the entire strip 21 from being withdrawn from the installation space 1101. The snap strip 20 is assembled to the snap seat 10 in such a manner that the anti-cracking portion 22 is engaged with the snap port 1201 and the assembly portion 212 is retained within the installation space 1101, thereby preventing the anti-cracking portion 22 from being separated from the assembly portion 212 due to external force.

[0050] Preferably, during the assembly of the anti-cracking part 22 and the soft strip 21 , the direction of the tension applied to the soft strip 21 is opposite to the direction of the tension applied to the anti-cracking part 22 , so as to reduce the difficulty of assembling the anti-cracking part 22 and the soft strip 21 .

[0051] In this way, when an attempt is made to crack the anti-counterfeiting function by pulling out the anti-cracking part 22 toward the direction of the straight insertion part 211, since the buckle strip 20 is plugged into the buckle seat 10 in such a way that the assembly part 212 is maintained in the installation space 1101, the soft strip body 21 can only be subjected to two pulling forces in opposite directions to make the whole body thinner, and it is impossible to apply an inward squeezing force to the straight insertion part 211 by hand or a toolbox to make the part with the largest diameter of the straight insertion part 211 thinner to allow the anti-cracking part 22 to pass through. Therefore, in this design, the disposable anti-counterfeiting buckle can effectively prevent counterfeiting.

[0052] refer to Figure 8 As a deformable material, the anti-cracking portion 22 is implemented as a soft rubber tube, such as a PU air tube. The hardness of the anti-cracking portion 22 is 70-98 Shore A. This material has a certain elasticity and is easily cracked when used alone as the buckle strip 20. The inner diameter of the anti-cracking portion 22 is R mm. The maximum diameter of the straight insertion portion 211 is (R + 0.2 * R) - (R + 0.3 * R) mm. The diameter of the limit portion 214 is greater than (R + 0.3 * R) mm.

[0053] Preferably, the inner diameter of the anti-cracking part 22 is 2 mm and the outer diameter is 3 mm, the minimum diameter of the straight insertion part 211 is 1.8 mm, the maximum diameter of the straight insertion part 211 is 2.4-2.6 mm, the diameter of the assembly part 212 is 1.5-1.8 mm, and the diameter of the limiting part 214 is 3.5 mm.

[0054] During the assembly process of the anti-cracking portion 22 and the soft strip 21, the anti-cracking portion 22 is subjected to tension and moves along the outer surface of the straight insertion portion 211. Within its own elastic force, it is gradually expanded by the straight insertion portion 211 until it moves to the outer periphery of the assembly portion 212. When the soft strip 21 is subjected to force and attempts to be withdrawn from the installation space 1101 through the insertion port 1102, the anti-cracking portion 22 becomes smaller in radial direction. However, due to the obstruction of the maximum diameter of the straight insertion portion 211, it is very difficult to remove the anti-cracking portion 22 in the reverse direction. If too much force is applied, the deformation of the entire soft strip 21 is too large, and the assembly portion 212 with the smallest diameter is preferably broken. Therefore, the anti-cracking portion 22 can also prevent the entire soft strip 21 from being withdrawn from the installation space 1101 by abutting against the snap structure 121 when the soft strip 21 becomes thinner due to tension. The snap strip 20 is plugged into the snap seat 10 in such a way that the anti-cracking part 22 is snapped into the bayonet 1201 and at least the part of the anti-cracking part 22 close to the extension part 213 is retained in the installation space 1101, so as to prevent the anti-cracking part 22 from being separated from the assembly part 212 due to external force.

[0055] Preferably, the buckle strip 20 is plugged into the buckle seat 10 in such a way that the anti-cracking part 22 is engaged with the bayonet 1201 and is maintained as a whole in the installation space 1101, so as to prevent the soft strip body 21 from becoming thinner due to tension, and the anti-cracking part 22 from being stretched thinner by applying two forces in opposite directions so as to no longer abut against the buckle structure 121, thereby causing anti-counterfeiting cracking.

[0056] As a deformable method, the snap strip 20 is assembled to the snap seat 10 in such a manner that the anti-cracking portion 22 is engaged with the snap opening 1201 and the end of the anti-cracking portion 22 adjacent to the extension portion 213 is retained within the installation space 1101. Thus, when the anti-cracking portion 22 is pulled toward the straight-insertion portion 211 and the soft strip 21 is pulled along the straight-insertion portion 211 toward the assembly portion 212, although the anti-cracking portion 22 becomes thinner, it is prevented from separating from the assembly portion 212 by the abutment of the snap structure 121, thereby preventing the anti-counterfeiting function from being compromised.

[0057] Preferably, the inner diameter of the anti-cracking portion 22 is greater than the diameter of the assembly portion 212, so as to further increase the difficulty of the anti-cracking portion 22 moving toward the straight insertion portion 211 to disengage from the assembly portion 212, thereby further improving the anti-counterfeiting performance.

[0058] It is worth mentioning that when the anti-breaking portion 22 is implemented as a rubber hose, the soft strip 21 and / or the anti-breaking portion 22 are lubricated and assembled as a whole, thereby improving the convenience of fitting the anti-breaking portion 22 around the outer periphery of the assembly portion 212. When the anti-breaking portion 22 is implemented as a soft rubber hose, the anti-breaking portion 22 is heat-treated and assembled as a whole with the soft strip 21. Since the soft rubber hose increases in elasticity after heating, it is easier to fit it around the outer periphery of the assembly portion 212.

[0059] An easy-insertion portion 23 is formed at one end of the snap strip 20 away from the snap seat 10. With reference to the direction in which the snap strip 20 extends into the installation space 1101 through the insertion opening 1102, the cross-sectional size of the easy-insertion portion 23 gradually increases.
