Description

Technical Field

[0001] The utility model relates to the technical field of packaging anti-counterfeiting, in particular to a hidden locking anti-counterfeiting buckle. Background Art

[0002] There is a phenomenon in the market where criminals recycle expensive wine boxes and resell the empty boxes with non-genuine wine. This not only disrupts market order but also harms the interests of original manufacturers and consumers. To prevent the proliferation of counterfeit and inferior products and protect brand image and consumer rights, the use of anti-counterfeiting buckle technology on packaging has become an important measure.

[0003] Anti-counterfeiting buckles include pull-off, tear-off, and press-on types. These buckles physically change when the package is opened, such as breaking, tearing, or deforming, thereby destroying the anti-counterfeiting structure and achieving the anti-counterfeiting purpose. Their working principle is that the buckle passes through the mounting hole on the other side of the box body and connects to the base, locking it tightly and making it impossible to separate. When opening the box, the buckle must be completely removed. The security teeth reserved on the box break during this tearing process, separating the box body from the base. This makes the box irreversible after opening, achieving the anti-counterfeiting purpose.

[0004] Although the existing anti-counterfeiting buckle of the packaging box is basically set on the inner wall of the packaging box to avoid being damaged, it is still possible for the thief to use a tool to penetrate into the packaging box through the gap between the box cover and the box base, and then pry open the locking mechanism on the anti-counterfeiting buckle to completely separate the box cover and the box base, thereby achieving the purpose of theft and counterfeiting. This situation is caused by the defect of the anti-counterfeiting buckle itself in the structure that can be pried open, so that even if the packaging box has the anti-counterfeiting buckle structure, it cannot achieve the real anti-counterfeiting function. Utility Model Content

[0005] In order to solve the problem in the prior art that the anti-counterfeiting buckle may be pried open, resulting in the failure of the anti-counterfeiting of the packaging box, the utility model provides a hidden locking anti-counterfeiting buckle.

[0006] The technical solution adopted in this utility model is:

[0007] A hidden locking anti-counterfeiting buckle comprises a male buckle and a female buckle that cooperate with each other, an elastic locking part is provided on one side of the inner wall of the female buckle, and an inwardly concave locking groove that cooperates with the elastic locking part is provided on the surface of the male buckle opposite to the elastic locking part, a locking tooth protruding toward the interior of the female buckle is provided on the inner wall of the female buckle on the side opposite to the elastic locking part, and a tooth groove that cooperates with the shape of the locking tooth is provided on the surface of the male buckle opposite to the locking tooth.

[0008] Furthermore, the male buckle and the female buckle are respectively made of hard materials.

[0009] Furthermore, the male buckle includes an integrally formed male buckle mounting part and an insert, the male buckle mounting part includes a male buckle mounting base plate and a reinforcement block arranged on the male buckle mounting base plate, the locking groove and the tooth groove are respectively arranged on both sides of the insert, and a guide head is also provided at the end of the insert.

[0010] Furthermore, the female buckle includes an integrally formed female buckle mounting base plate and a locking sleeve, the locking sleeve is arranged on the female buckle mounting base plate, and the elastic locking member and locking teeth are respectively arranged on both sides of the inner wall of the locking sleeve.

[0011] Furthermore, a reinforcing rib plate is connected between the female buckle mounting base plate and the locking sleeve.

[0012] Furthermore, the cross section of the elastic locking member is hook-shaped, the adjacent two side walls of the elastic locking member are connected at a vertical angle, and the locking groove is configured as a square groove that matches the two vertical outer walls of the elastic locking member.

[0013] The beneficial effects of the utility model are:

[0014] The anti-counterfeiting buckle of the present invention is provided with a hidden elastic locking part and locking teeth on the inner wall of the female buckle, which cooperates with the concave locking grooves and locking teeth respectively provided on both sides of the male buckle, so that the locking part of the anti-counterfeiting buckle is hidden inside the male and female buckles, thereby shielding the locking part of the anti-counterfeiting buckle and effectively preventing it from being pried open from the outside; when the male buckle is inserted into the female buckle until the elastic locking part is buckled into the locking groove, the elastic locking part can no longer exit the locking groove in any direction, and the elastic locking part is now in its own Under the action of elasticity, the elastic force is transmitted to the male buckle through contact with the locking groove, so that the tooth groove on the other side of the male buckle and the locking teeth on the female buckle can be firmly locked together; since the fastening surfaces on both sides of the male buckle are hidden inside and are not in the same plane as the gap between the male buckle and the female buckle, even if a tool is used to probe through the gap, the fastening surface cannot be touched, and there is no leverage point to pry up the fastening part, so it can effectively avoid the anti-counterfeiting buckle from being separated without damage from the outside, thereby improving the safety and anti-counterfeiting performance of the anti-counterfeiting buckle.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] This utility model is a hidden locking anti-counterfeiting buckle, mainly used for anti-counterfeiting of wine packaging boxes. It has the characteristics of the locking part hidden inside the male buckle 1 and the female buckle 2. After the buckle is completed, it can prevent counterfeiters from inserting through the gap to pry open the anti-counterfeiting buckle. The buckle is more secure and stable, and the safety and anti-counterfeiting performance are significantly improved. Specifically, the utility model can be implemented as follows:

[0029] Example 1

[0030] This embodiment is a basic implementation plan of the anti-counterfeiting buckle of the utility model. Please refer to Figure 1-Figure 3 The anti-counterfeiting buckle can be composed of two parts, namely a male buckle 1 for insertion and locking, and a female buckle 2 for providing internal locking scenes and conditions. The male buckle 1 and the female buckle 2 can be made into one piece during manufacturing. When in use, the male buckle 1 and the female buckle 2 are respectively installed on the lid and the base of the packaging box, preferably installed inside the packaging box. The elastic locking parts 3 and the locking teeth 5 provided on the two side walls inside the female buckle 2 are the key to realizing hidden locking in this utility model:

[0031] The elastic locking member 3 can cooperate with the concave locking groove 4 on the male buckle 1. When the male buckle 1 is initially inserted into the female buckle 2, the elastic locking member 3 is deformed under a certain elasticity to leave space for the movement of the male buckle 1. When the male buckle 1 is inserted into the female buckle 2 to a certain position, the elastic locking member 3 will be buckled into the locking groove 4. Since the locking groove 4 is concave, the contact surface of the elastic locking member 3 after being partially buckled into it will be hidden in the locking groove 4. Under the action of elasticity, the elastic locking member 3 will fit with the locking groove 4 under the elastic pre-tightening force. At this time, if you want to probe into the fitting position of the elastic locking member 3 and the locking groove 4 from the gap of the external packaging, you need to bend it at multiple large angles, which greatly increases the difficulty of counterfeiting.

[0032] When the elastic locking member 3 is buckled into the locking groove 4, the locking teeth 5 on the inner wall of the female buckle 2 will also be engaged with the tooth groove 6 set on the male buckle 1 at the same time. The tooth tip of the locking teeth 5 can be set as an acute-angled tooth, and the shape of the tooth groove 6 is correspondingly set to be the same as the shape of the locking teeth 5. Similarly, since the locking surface of the locking teeth 5 and the tooth groove 6 is hidden inside the male buckle 1, it is difficult to penetrate from the outside to pry it open, and the elastic force from the elastic locking member 3 will squeeze the male buckle 1 to one side of the locking teeth 5, making the locking teeth 5 and the tooth groove 6 more tightly engaged, thereby further improving the stability and security of the engagement and completing the engagement of the entire anti-counterfeiting buckle. It should be noted that in the size design of the anti-counterfeiting buckle, the gap between the male buckle 1 and the female buckle 2 after assembly should be as small as possible, that is, the two should fit together as completely as possible to ensure that there is no space for prying.

[0033] The anti-counterfeiting buckle structure of this embodiment hides the buckling contact parts on both sides inside the lock groove 4 and the tooth groove 6 of the male buckle 1, which are difficult to access from the outside, and it is impossible to find a leverage point to pry the male buckle 1 and the female buckle 2 apart, achieving a more thorough anti-counterfeiting effect.

[0034] Example 2

[0035] This embodiment is a further implementation plan based on Example 1. In order to limit the elastic deformation range of the anti-counterfeiting buckle itself and further prevent counterfeiters from prying the anti-counterfeiting buckle open through elastic deformation, and also to enhance the elastic pre-tightening force of the elastic locking part 3 to enhance the stability of the fastening, this embodiment uses hard materials as the components of the male buckle 1 and the female buckle 2. For example, hard plastic and other materials can be selected as the components of the anti-counterfeiting buckle. It should be noted that the hard material should at least ensure that the deformation of the elastic locking part 3 when the male buckle 1 is inserted into the female buckle 2 can leave insertion space for the male buckle 1, and the material cannot be too hard and brittle to avoid the elastic locking part 3 from breaking during the insertion process, which makes the packaging anti-counterfeiting ineffective.

[0036] Example 3

[0037] This example is a further implementation plan based on Example 1. Please refer to Figure 6-Figure 7 In order to support the stable installation between the male buckle 1 and the packaging box and limit the depth of the male buckle 1 inserted into the female buckle 2 from the structure of the anti-counterfeiting buckle, the male buckle 1 is divided into a male buckle mounting part 7 and an inserting part 8. Part of the male buckle mounting part 7 does not enter the female buckle 2, and the male buckle mounting base 9 is fixedly connected to the inner wall of the packaging box to provide support for the movement of the male buckle 1, and the reinforcing block 10 is connected between the male buckle mounting base 9 and the inserting part 8 to ensure the installation strength of the male buckle mounting part 7 and the connection strength at the position between the male buckle mounting base 9 and the inserting part 8; a guide head 11 is provided on the end of the inserting part 8 facing the insertion into the female buckle 2, and the guide head 11 can be set to a cone shape to facilitate the insertion of the inserting part 8, and guide and extrude the elastic locking part 3 during the insertion process to make it elastically deformed, providing space for the insertion of the male buckle 1 until the elastic locking part 3 is buckled into the locking groove 4, and the guide head 11 completes the guiding function.

[0038] The shape and structure of the male buckle 1 in this embodiment make the connection between the anti-counterfeiting buckle and the packaging box more firm and stable, and also make it easier to insert the male buckle 1 into the female buckle 2, which can effectively avoid damage to the anti-counterfeiting buckle during the insertion operation.

[0039] Example 4

[0040] This example is a further implementation plan based on Example 1. Please refer to Figure 4-Figure 5 、 Figures 8-10 The clasp 13 is provided with an elastic locking member 3 and a locking tooth 5 for inserting and fastening the male clasp 1, so as to realize the locking and anti-counterfeiting function of the anti-counterfeiting buckle; the male clasp 1 and the female clasp 2 are respectively installed on the lid or the box seat of the packaging box, and can be specifically selected according to the structural form of the packaging box. For example, for a packaging box with a separate lid and a box seat, the male clasp 1 can be set on the box seat and the female clasp 2 can be set on the inner wall of the lid. The anti-counterfeiting buckle can be assembled together by aligning the female clasp 2 of the lid with the male clasp 1 of the box seat for closing and inserting. The connection method of the anti-counterfeiting buckle and the packaging box can be glued with an embedded structure. Those skilled in the art can select according to actual needs.

[0041] Example 5

[0042] This example is a further implementation plan based on Example 4. Please refer to Figure 1 、 Figure 4 and Figure 8In order to further enhance the overall strength of the anti-counterfeiting buckle after assembly and prevent counterfeiters from physically damaging the buckle and obtaining a complete packaging box, a reinforcing rib 14 is provided between the female buckle mounting base 12 and the locking buckle sleeve 13 in this embodiment to enhance the stress resistance of the anti-counterfeiting buckle. Figure 1 and Figure 4 The figure in the figure shows one of the distribution structures of the reinforcing ribs 14. The reinforcing ribs 14 are arranged on both sides of the locking sleeve 13 to strengthen and support it, so as to achieve the effect of improving strength. In addition to this structure, reinforcing ribs 14 can also be set on the upper surface of the locking sleeve 13, or the reinforcing ribs 14 can be set as a strip structure surrounding the outer surface of the locking sleeve 13. Its distribution only needs to avoid the opening position of the elastic locking member 3.

[0043] In this embodiment, a reinforcing rib 14 is added to the structure of the female buckle 2, which can further increase the stress that the anti-counterfeiting buckle can withstand and prevent it from being physically damaged.

[0044] Example 6

[0045] This example is a further implementation plan based on Example 1. Please refer to Figure 3 、 Figure 6 In order to further improve the fastening stability between the elastic locking member 3 and the locking groove 4 and hide the fastening surface in a difficult-to-access position through a more optimized shape structure, the elastic locking member 3 is configured as a hook shape in this embodiment, such as Figure 3 As shown, the hook-type elastic locking member 3 does not use its hook shape to hook the locking groove 4 to achieve locking, but provides elastic deformation ability through the hook shape, and engages with the locking groove 4 through the back of the hook of the hook-shaped part; preferably, the two adjacent outer walls of the elastic locking member 3 are at right angles to each other, and the shape of the locking groove 4 is also correspondingly set to a square groove with a vertical angle to match the vertical part of the elastic locking member 3. The advantage of this shape setting is that if it is set to an obtuse angle, it is easy to penetrate from the gap to contact the locking surface, and if it is set to an acute angle, the stress distribution of the elastic locking member 3 will be poor when the box cover and the box base of the packaging box are to be violently separated, which may easily cause damage to the elastic locking member 3. Therefore, setting it to a vertical angle can achieve the best hiding of the locking surface while ensuring a good stress distribution.

[0046] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
