Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging anti-counterfeiting technology, and in particular to a compact packaging anti-counterfeiting buckle. Background Technology
[0002] Anti-counterfeiting buckles on packaging boxes typically employ a one-time locking structure made of high-strength plastic or metal, combined with physical destructive design features such as slot breakage and easy-tear lines. The principle is to forcibly destroy the lock or trigger visible traces when opened, while simultaneously working with a digital verification system to achieve anti-counterfeiting. However, this type of structure still has significant drawbacks. First, to balance tamper resistance and production convenience, physical locks often use a multi-component assembly design, resulting in a bulky size that is difficult to adapt to various packaging boxes. Furthermore, the locking structure of some locks lacks precision, and components may deform rather than break under forceful prying, allowing counterfeiters to recycle the packaging without damage. Utility Model Content
[0003] To address the problem that existing packaging anti-counterfeiting buckles are easily pried open due to excessive structural flexibility and insufficient fitting precision, this utility model provides a compact packaging anti-counterfeiting buckle.
[0004] The technical solution adopted in this utility model is:
[0005] A compact packaging anti-counterfeiting buckle includes a male buckle and a female buckle that cooperate with each other. The male buckle is provided with a first fastening part and a second fastening part, which are located on opposite sides of the male buckle. The female buckle is provided with a first fastening spring and a second fastening spring, and a mating gap for inserting the male buckle is provided between the first fastening spring and the second fastening spring. A middle limiting plate is provided in the middle of the female buckle.
[0006] The first and second fastening parts are used to insert into the mating gap from one end of the female buckle and extend from the other end of the female buckle, and respectively cooperate with the first and second fastening springs to restrict the movement of the male buckle in the pull-out direction; the intermediate limiting plate is used to cooperate with the male buckle and restrict the movement of the male buckle in the insertion direction.
[0007] Furthermore, the female buckle includes a female buckle base plate and a female buckle engagement mechanism disposed on the female buckle base plate. The intermediate limiting plate is disposed at the middle position of the female buckle engagement mechanism in a direction perpendicular to the female buckle base plate. A set of the first and second fastening springs are respectively disposed on both sides of the intermediate limiting plate.
[0008] Furthermore, the female buckle includes a female buckle base plate and a female buckle mating mechanism disposed on the female buckle base plate. The female buckle mating mechanism includes a support frame and a first snap-fit spring and a second snap-fit spring respectively connected to the top and bottom sides of the support frame. The support frame is provided with an insertion port on the other side opposite to the first snap-fit spring and the second snap-fit spring.
[0009] Furthermore, the mating surfaces of the first snap-fit spring and the first snap-fit part, and the mating surfaces of the second snap-fit spring and the second snap-fit part are arranged parallel to each other and do not overlap.
[0010] Furthermore, the male buckle includes a packaging mating part for connecting with the outer packaging and an insertion part for inserting into the female buckle. The insertion part has a limiting slot that mates with the intermediate limiting plate. The first fastening part and the second fastening part are respectively disposed on the two sides of the end of the insertion part.
[0011] Furthermore, the surface of the packaging mating part is provided with a mating protrusion, which is used to mate with the connection hole opened on the packaging.
[0012] The beneficial effects of this utility model are:
[0013] This invention features a male buckle that, after being inserted into the female buckle, extends from the other end and limits the direction of its pull-out movement. Simultaneously, a middle limiting plate restricts further insertion of the male buckle from the other direction. This prevents the male buckle from moving in either the insertion or pull-out direction. The movable gap between the male and female buckles is extremely small, resulting in a more secure and stable lock. This structure ensures that the mating position of the male and female buckles is not inside the female buckle but on its outer surface. Therefore, the female buckle does not require additional internal space for its mating structure, allowing for a smaller design. Consequently, the mating structure between the male and female buckles can be more compact, effectively preventing deformation and prying. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] Example 1
[0027] A compact packaging anti-counterfeiting buckle, such as Figures 1-8 As shown, the device includes a male buckle 1 and a female buckle 2 that cooperate with each other. The male buckle 1 is provided with a first engaging part 121 and a second engaging part 122, which are located on opposite sides of the male buckle. The female buckle 2 is provided with a first engaging spring 221 and a second engaging spring 222, with a mating gap between the first engaging spring 221 and the second engaging spring 222 for inserting the male buckle 1. A middle limiting plate 223 is provided in the middle of the female buckle 2. The first engaging part 121 and the second engaging part 122 are used to insert into the mating gap from one end of the female buckle 2 and extend from the other end of the female buckle 2, and respectively cooperate with the first engaging spring 221 and the second engaging spring 222 to restrict the movement of the male buckle 1 in the pull-out direction. The middle limiting plate 223 is used to cooperate with the male buckle 1 and restrict the movement of the male buckle 1 in the insertion direction.
[0028] The working process of the anti-counterfeiting buckle of this utility model is as follows: after the male buckle 1 is inserted into the mating gap in the female buckle 2, it continues to move until the male buckle 1 extends out from the other end of the female buckle 2, and the first fastening part 121 and the second fastening part 122 of the male buckle 1 also pass the positions of the first fastening spring 221 and the second fastening spring 222, respectively. Figure 2In the engaged state, when the male buckle 1 is to be pulled out, the mating surfaces of each engaging part and the engaging spring contact and abut against each other, limiting the direction of movement of the male buckle 1. Simultaneously, the intermediate limiting plate 223 engages with the male buckle 1. When the male buckle 1 is inserted to a certain depth, i.e., at the position where the engaging part and the engaging spring engage, the intermediate limiting plate 223 can block further insertion of the male buckle 1 at that position, thus restricting its further movement from another direction. This achieves the goal of preventing the male buckle 1 from moving in either the insertion or extraction direction. The movable gap between the male buckle 1 and the female buckle 2 can be minimized, resulting in a more secure and stable lock between them. This structure places the mating position of the male buckle 1 and the female buckle 2 on the outer side of the female buckle 2, rather than inside it. This eliminates the need for additional internal space in the design of the female buckle 2, allowing for a smaller size and a more compact mating structure between the male buckle 1 and the female buckle 2, effectively preventing deformation and prying.
[0029] Example 2
[0030] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 3 As shown, the female buckle 2 includes a female buckle base plate 21 and a female buckle engagement mechanism 22 disposed on the female buckle base plate 21. The intermediate limiting plate 223 is disposed in the middle position of the female buckle engagement mechanism 22 along a direction perpendicular to the female buckle base plate 21. A set of the first fastening spring 221 and the second fastening spring 222 are respectively disposed on both sides of the intermediate limiting plate 223.
[0031] like Figure 3 As shown, the intermediate limiting plate 223 divides the female buckle engagement mechanism 22 into two symmetrical parts. A set of snap-fit springs are respectively provided on both sides of the intermediate limiting plate 223, and the male buckle 1 is provided with two symmetrical snap-fit parts to cooperate with the structure of the female buckle engagement mechanism 22. The intermediate limiting plate 223, which is set in the direction perpendicular to the female buckle base plate 21, can cooperate with the male buckle 1 by utilizing the thickness dimension. The slot of the male buckle 1 can be set to be narrower to improve the compactness and stability of the overall structure.
[0032] Example 3
[0033] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 3 As shown, the female buckle 2 includes a female buckle base plate 21 and a female buckle mating mechanism 22 disposed on the female buckle base plate 21. The female buckle mating mechanism 22 includes a support frame and a first snap-fit spring piece 221 and a second snap-fit spring piece 222 respectively connected to the top and bottom sides of the support frame. The support frame is provided with an insertion port on the other side opposite to the first snap-fit spring piece 221 and the second snap-fit spring piece 222.
[0034] like Figure 3As shown, the insertion port at the support frame is divided into two symmetrical insertion ports by the middle limiting plate 223. When the male buckle 1 and the female buckle 2 are engaged, the two corresponding parts of the male buckle 1 need to be inserted into the insertion ports on both sides simultaneously, and the engagement of the two sides of the fastening part and the fastening spring is completed at the same time. That is, the translational position of the two sides of the male buckle 1 and the female buckle 2 can also be locked, so that the male buckle 1 can no longer move in any direction on the plane of the female buckle base plate 21. Even if the two sides of the female buckle engagement mechanism 22 are semi-open structures (such as...), Figure 2 As shown in the side view, a portion of the male buckle 1 can be seen inside. Under the support and limitation of the middle limiting plate 223 and the professional frame, the locking of the male buckle 1 and the female buckle 2 is not affected. Compared with making the female buckle 2 a fully enclosed structure, it can save some materials and reduce production costs.
[0035] Example 4
[0036] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 2 As shown, the mating surfaces of the first snap-fit spring 221 and the first snap-fit part 121, and the mating surfaces of the second snap-fit spring 222 and the second snap-fit part 122, are arranged parallel to each other and do not overlap. This structure ensures that the snap-fit part of the male buckle 1 and the snap-fit spring of the female buckle 2 are arranged in an "interlaced" shape, i.e., as shown... Figure 2 The upper and lower halves of the male buckle 1 are not symmetrically arranged. This staggered arrangement makes the fastening surfaces on both sides of the male buckle 1 not in the same plane. When a counterfeiter tries to pry open the male buckle 1 and the female buckle 2 from one side, the required deformation positions on both sides are different, making it more difficult to pry open the fastening position on the other side. This ensures the anti-counterfeiting performance of the anti-counterfeiting buckle and enhances its security.
[0037] Example 5
[0038] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 4 , Figure 5 As shown, the male buckle 1 includes a packaging mating part 11 for connecting with the outer packaging and an insertion part 12 for inserting into the female buckle 2. The insertion part 12 has a limiting slot 123 that mates with the intermediate limiting plate 223. The first fastening part 121 and the second fastening part 122 are respectively disposed on the two sides of the end of the insertion part 12. Figure 4 As shown, the packaging mating part 11 and the insertion part 12 of the male buckle 1 can be separated by the middle raised rib. The surface of the packaging mating part 11 is attached to the inner side of the packaging, for example, attached to the side of the box lid of the packaging box. The female buckle 2 is installed on the inner wall of the packaging box at the corresponding position. The male buckle 1 has a limiting slot 123 that mates with the middle limiting plate 223. The length of the limiting slot 123 is set according to the mutual interlocking position of the fastening part of the male buckle 1 and the female buckle 2 and the fastening spring. When the male buckle 1 and the female buckle 2 are engaged, as shown... Figure 8As shown, the insertion part 12 of the male buckle 1 is fully inserted into the female buckle 2 and can no longer move. The bottom edge of the raised rib in the middle protects the packaging from being damaged by the middle limiting plate 223, thereby improving the convenience of the packaging during operation and making it easier to determine whether the male buckle 1 has been properly engaged with the female buckle 2.
[0039] Example 6
[0040] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 1 , Figure 2 As shown, a mating protrusion 111 is provided on the surface of the packaging mating part 11. The mating protrusion 111 is used to mate with the connecting hole opened on the packaging. Taking the paper packaging box used in Embodiment 5 as an example, the protrusion is used to mate with the limiting hole of the same shape opened on the box lid, thereby strengthening the connection strength between the packaging box and the anti-counterfeiting buckle. When the packaging is locked and the box lid is to be opened directly by breaking the anti-counterfeiting buckle without damaging the packaging, the connection between the mating protrusion 111 and the limiting hole can bear a certain force to prevent the anti-counterfeiting buckle from being damaged before the packaging, thereby avoiding the loss of the packaging's anti-counterfeiting function, reducing the load pressure on the anti-counterfeiting buckle during use, and further improving the security and anti-counterfeiting performance. Preferably, the mating protrusion 111 can be cylindrical or cuboid in shape, and those skilled in the art can set it according to the needs of the packaging box mating.
[0041] 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.
