Description

Technical Field

[0001] This utility model relates to the field of packaging anti-counterfeiting technology, and in particular to a packaging anti-counterfeiting buckle. Background Technology

[0002] Anti-counterfeiting buckles on packaging are a key physical anti-counterfeiting technology that has emerged to combat the proliferation of counterfeit and substandard products. Traditional packaging is easily imitated and replaced, leading to damage to corporate brand image and infringement of consumer rights. To solve this problem, anti-counterfeiting buckles have constructed a technical system that combines anti-counterfeiting performance with ease of operation through innovative integration of materials science and precision structural design. Its core principle lies in using special plastics, steel wire, or polymer composite materials, combined with a one-time locking mechanism such as fracture grooves and elastic sheet expansion fastening, ensuring that the structure permanently fails after the packaging is opened. During operation, the anti-counterfeiting buckle undergoes four major stages: precise installation, irreversible sealing, retention of tamper-evident marks, and multi-dimensional verification. During installation, the buckles are firmly attached to the inner wall of the packaging box via a fixing plate, and the injection molding parameters are adjusted to ensure structural precision. During sealing, the buckle body is squeezed when the box lid is closed, and the expansion of the elastic sheet and the strip hole achieves a tight fit, forming a physical barrier that cannot be opened without leaving a mark. In the anti-pry verification process, the horizontal bar and the diagonal block design can prevent illegal prying. If forcibly broken, the fracture groove will break and leave a mark. Consumers can verify authenticity by observing the integrity of the box lid's snap-fit ​​or scanning the QR code.

[0003] The locking mechanism of existing anti-counterfeiting buckles is usually located on the female buckle, making it difficult to observe from the outside whether the buckle is properly engaged. Because it is difficult to judge the engagement, excessive force is often used during operation to avoid unsuccessful engagement, which can damage the packaging or the anti-counterfeiting buckle and increase the packaging waste rate. Utility Model Content

[0004] To address the problem that existing anti-counterfeiting buckles are easily damaged due to excessive force during operation due to inconvenient operation, this utility model provides a packaging anti-counterfeiting buckle.

[0005] The technical solution adopted in this utility model is:

[0006] A packaging anti-counterfeiting buckle includes a male buckle and a female buckle that cooperate with each other. The female buckle is provided with a female buckle mating part. One end of the female buckle mating part is provided with an insertion port. The female buckle mating part is provided with a fastening spring. The fastening spring is provided with a spring hook part. The spring hook part is located inside the female buckle mating part. The male buckle is provided with a fastening plug that cooperates with the fastening spring. A dividing mark is provided on the surface of the male buckle at the position of the insertion port.

[0007] The dividing mark is used to separate the part of the male buckle inserted into the female buckle from the external part, and the position of the fastening operation is determined by the relative position of the dividing mark and the insertion port.

[0008] Furthermore, the other end of the female fastener opposite the insertion port is configured to be closed and form an insertion space, and the cross-section of the female fastener is U-shaped.

[0009] Furthermore, the female buckle is provided with an intermediate guide in the middle, which divides the interior of the female buckle into two insertion spaces. Each insertion space is provided with a snap-fit ​​spring. The male buckle is provided with a guide groove that mates with the intermediate guide. Snap-fit ​​plugs are provided on the male buckles on both sides of the guide groove.

[0010] Furthermore, the male buckle surface is divided into an insertion part and a packaging mating part by the two sides of the dividing mark, the buckle plug is disposed at the end of the insertion part, and a packaging limiting block is disposed on the packaging mating part;

[0011] The packaging limiting block is used to connect with the limiting hole opened on the packaging.

[0012] Furthermore, the spring clip engagement part is disposed on one side of the male buckle, and an anti-pry protrusion is provided in the female buckle fitting part near the end of the male buckle plug. The anti-pry protrusion is used to block and limit the deformation of the male buckle plug.

[0013] Furthermore, the dividing mark is disposed on the male fastening surface on the same side as the spring clip engaging part, and the shape of the male fastening surface between the dividing mark and the spring clip engaging part matches the shape of the engaging spring clip.

[0014] Furthermore, the spring clips are symmetrically arranged on both sides of the male buckle, and two spring clips are symmetrically arranged on the inner wall of the female buckle fitting.

[0015] Furthermore, the dividing mark is disposed on the side surface of the male buckle away from the bottom of the female buckle, and the dividing mark is configured as a rib-shaped part arranged parallel to the surface where the insertion port is located.

[0016] The beneficial effects of this utility model are:

[0017] This invention features a dividing mark on the male buckle position corresponding to the insertion port of the female buckle after the male buckle is inserted. This allows operators to more intuitively judge the size of the male buckle's insertion portion during the insertion and engagement of the anti-counterfeiting buckle, thus enabling better control of the required insertion depth and facilitating the assessment of whether the male and female buckles are properly engaged. When using an operating device to insert the male buckle into the female buckle, the dividing mark further quantifies the required insertion depth, allowing for better adjustment of the device's operating parameters. Furthermore, when the dividing mark is set higher than the insertion port, it further aids in determining whether the male buckle is properly engaged by blocking the insertion port, thereby improving operational efficiency, preventing damage to the packaging or anti-counterfeiting buckles due to excessive force, and reducing the scrap rate in packaging production.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Example 1: A packaging anti-counterfeiting buckle, such as Figures 1-2 , Figures 6-7 As shown, the device includes a male buckle 1 and a female buckle 2 that cooperate with each other. The female buckle 2 is provided with a female buckle mating part 21. One end of the female buckle mating part 21 is provided with an insertion port 22. The female buckle mating part 21 is provided with a fastening spring piece 211. The fastening spring piece 211 is provided with a spring piece hook part 212, which is located inside the female buckle mating part 21. The male buckle 1 is provided with a fastening plug 111 that cooperates with the fastening spring piece 211. After being inserted into the female fastener 21, it continues to move forward and comes into contact with the fastening spring 211. Under the mutual sliding contact of the inclined surfaces of the two, the spring force pushes the fastening spring 211 up until the fastening plug 111 passes the position of the spring hook part 212 on the fastening spring 211. At this time, the fastening spring 211 rebounds under the action of the spring force and locks the fastening plug 111 of the male fastener 1 inside. When you want to pull out the fastening plug 111, it will be blocked and limited by the fastening spring 211.

[0033] To facilitate a more intuitive determination of the required operating distance for the male buckle 1 to engage and lock into place with the female buckle 2, a dividing mark 13 is provided on the surface of the male buckle 1 at the insertion port 22. The dividing mark is used to demarcate the portion of the male buckle 1 inserted into the female buckle fitting 21 from the external portion, and the position of the engagement operation is determined by the relative position of the dividing mark and the insertion port 22.

[0034] This invention provides a dividing mark on the male buckle 1, corresponding to the insertion port 22 of the female buckle 21 after the male buckle 1 is inserted into the female buckle 2. This allows operators to more intuitively judge the size of the insertion portion 11 of the male buckle 1 when inserting and engaging the anti-counterfeiting buckle. This enables better control of the required insertion depth and helps determine whether the engagement between the male buckle 1 and the female buckle 2 is sufficient. When using an operating device to insert the male buckle 1 into the female buckle 2, the dividing mark quantifies the required insertion depth of the male buckle 1, allowing for better adjustment of the operating device's parameters. When the height of the dividing mark is higher than the height of the insertion port 22, the dividing mark further facilitates judgment of whether the male buckle 1 is in place by blocking and limiting the insertion port 22. This improves operational efficiency, prevents damage to the packaging or anti-counterfeiting buckle due to excessive force, and reduces the scrap rate in packaging production.

[0035] Exemplary, such as Figures 1-2 As shown, the dividing mark can be set as a strip-shaped protrusion, with the edge of the protrusion close to the insertion port 22. The relative position of the edge to the insertion port 22 is used to mark whether the insertion part 11 of the male buckle 1 has been inserted to a sufficient depth. As another example, such as... Figures 6-7 As shown, the dividing mark can be set as a ramp. The appropriate insertion position of the male buckle 1 can be marked by the mutual cooperation between the ramp and the inner wall of the female buckle 21 and the mutual blocking and limiting between the top of the ramp and the insertion port 22. It can also achieve the functions of marking and easy judgment.

[0036] Example 2: This example is based on the foregoing examples, such as... Figure 2 , Figure 7 As shown, in this embodiment, the other end of the female buckle fitting 21 opposite to the insertion port 22 is set in a closed state to form an insertion space. The cross-section of the female buckle fitting 21 is U-shaped. The space enclosed in the middle of the U-shape is the part for the male buckle 1 to be inserted. The closed structure at the other end of the insertion port 22 is used to block the further movement of the male buckle 1, thereby further limiting the mating position of the male buckle 1.

[0037] As a preferred implementation method, such as Figure 3 , Figure 8 As shown, a middle guide 23 is provided in the middle of the female fastener 21. The middle guide 23 divides the interior of the female fastener 21 into two insertion spaces. Each insertion space is provided with a snap-fit ​​spring 211. The male fastener 1 has a guide groove 112 that mates with the middle guide 23. Snap-fit ​​plugs 111 are respectively provided on both sides of the male fastener 1 via the guide groove 112. The middle guide 23 can be configured as follows: Figure 3The plate-shaped design features a narrower width and a tighter fit between the intermediate guide member 23 and the guide groove 112; it can also be configured as follows: Figure 8 The intermediate guide 23 shown has a structure with a pointed conical guide end, which is characterized by more obvious insertion guidance and easier operation.

[0038] As a preferred implementation method, such as Figure 3 , Figure 5 , Figure 8 , Figure 10 As shown, the surface of the male buckle 1 is divided into an insertion part 11 and a packaging mating part 12 by the two sides of the dividing mark part 13. The fastening plug 111 is provided at the end of the insertion part 11, and the packaging mating part 12 is provided with a packaging limiting block 121; wherein, the packaging limiting block 121 is used to engage with the limiting hole opened on the packaging.

[0039] In this embodiment, the surface of the packaging mating part 12 is attached to the inner side of the packaging, for example, attached to the side of the box lid of the packaging box, while the female buckle 2 is installed on the inner wall of the packaging box at the corresponding position. When the male buckle 1 and the female buckle 2 are mated, the insertion part 11 of the male buckle 1 can be fully inserted into the female buckle 2 and cannot move further. The bottom edge of the dividing mark part protects the packaging from being damaged, thereby improving the convenience of the packaging during operation.

[0040] Taking a paper packaging box as an example, the packaging limiting block 121 is used to cooperate with the limiting hole of the same shape opened on the lid of the packaging box, thereby strengthening the connection between the packaging box and the anti-counterfeiting buckle. When the packaging is locked and you want to open the lid directly by breaking the anti-counterfeiting buckle without damaging the packaging, the connection between the packaging limiting block 121 and the limiting hole can bear a certain force to prevent the anti-counterfeiting buckle from being damaged before the packaging, thus avoiding the loss of the packaging's anti-counterfeiting function. This reduces the load pressure on the anti-counterfeiting buckle during use and further enhances its security and anti-counterfeiting performance. Preferably, the packaging limiting block 121 is shaped as follows: Figure 1 or Figure 6 The cylindrical or cuboid shape shown can be used, and those skilled in the art can set it according to the packaging box matching needs.

[0041] Example 3: This example is based on any of the foregoing examples and is a preferred embodiment of the present invention. In this example, as... Figures 6-10 As shown, the spring clip engagement part 212 is disposed on one side of the male buckle 1, and an anti-pry protrusion 213 is provided inside the female buckle mating part 21 near the end of the male buckle 1 plug. The anti-pry protrusion 213 is used to block and limit the deformation of the male buckle 1 plug. Figure 6 , Figure 7As shown, the anti-pry protrusion 213 can be configured as a protrusion with an arc-shaped surface, thereby limiting the end of the male buckle 1 when it wants to deform and move to the other side of the spring clip engagement part 212, so that the deformation of the male buckle 1 plug in the other side is limited and not enough to separate the engagement between the plug end and the spring clip engagement part 212, thereby preventing the female buckle 2 from being pulled out after the male buckle 1 is pried open.

[0042] As a preferred implementation method, such as Figure 6 , Figure 7 As shown, the dividing mark is disposed on the surface of the male buckle 1 on the same side as the spring clip engagement part 212. The surface shape of the male buckle 1 between the dividing mark and the spring clip engagement part 212 matches the shape of the engaging spring clip 211. This structure is based on the embodiment 1, in which the dividing mark is set as a slope, and its surface slope can be set to a shape that can fit against the spring clip engagement part 212 of the female buckle 2. Thus, while serving as a dividing mark, it can also play a limiting role when it cooperates with the spring clip engagement part 212.

[0043] Example 4: This example can be based on the technical solutions of Examples 1 and 2. In this example, as... Figures 1-5 As shown, the spring clips 212 are symmetrically arranged on both sides of the male buckle 1, and two snap-fit ​​spring clips 211 are symmetrically arranged on the inner wall of the female buckle fitting 21. The spring clips 212 and snap-fit ​​spring clips 211 arranged symmetrically on both sides cooperate with each other, so that the deformation space on both sides of the male buckle 1 is restricted. When it is desired to squeeze and deform from one side to the other side, the deformation makes the other side of the male buckle 1 more tightly fitted and unable to disengage from the female buckle fitting 21, thereby achieving the function of preventing it from being pried open.

[0044] As a preferred implementation method, such as Figure 1 , Figure 2 The dividing mark shown is located on the surface of the male buckle 1 facing away from the bottom of the female buckle 2. The dividing mark is set as a rib-like part parallel to the surface where the insertion port 22 is located. This structure is based on the one described in Embodiment 1, where the dividing mark is set as a raised rib. The height of the rib can be selected according to design needs to be higher than the height of the insertion port 22, thereby playing the same blocking and limiting role as the dividing mark in Embodiment 3. On the one hand, it can be used to mark the insertion position of the male buckle 1 and prevent the male buckle 1 from being inserted further. On the other hand, it can also form a dividing point connecting with the packaging box part, so that the packaging box part can stay outside the female buckle mating part 21, and the insertion part 11 and the packaging mating part 12 of the male buckle 1 can stay more accurately in their respective positions after mating with the female buckle 2.

[0045] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
