Description

Technical Field

[0001] The utility model relates to the technical field of packaging anti-counterfeiting, in particular to an anti-counterfeiting buckle for a packaging box with high stability. 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 provided with a locking part on the inner wall of the packaging box to prevent it from being damaged, there is some gap and space between the two parts that cooperate with each other for quick assembly. Therefore, after locking, the locking parts of the anti-counterfeiting buckle can still move relative to each other, resulting in that the box lid of the packaging box cannot be stably fixed on the box base. The thief may penetrate through the gap caused by the shaking of the box lid to break the anti-counterfeiting buckle, thereby losing the anti-counterfeiting function. Utility Model Content

[0005] In order to solve the problem in the prior art that after locking, there is still a gap between the locking parts of the anti-counterfeiting buckle, which allows relative displacement and causes instability, the utility model provides a high-stability anti-counterfeiting buckle for a packaging box.

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

[0007] A high-stability anti-counterfeiting buckle for a packaging box comprises a male buckle and a female buckle that cooperate with each other, an elastic locking piece 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 piece is provided on the side of the male buckle opposite to the elastic locking piece, a limiting block is provided in the locking groove, and the limiting block is used to limit the movement of the elastic locking piece in the locking groove, and 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 piece, and a rack segment is provided on the side of the male buckle opposite to the locking tooth, and the rack segment is used to cooperate with the locking tooth for locking.

[0008] Furthermore, a limiting section is provided on one side of the locking groove on the male buckle, and the limiting section is provided in a slope shape. An end face limiting piece is provided on the end face of the female buckle opposite to the limiting section, and the end face limiting piece is used to cooperate with the limiting section for limiting.

[0009] Furthermore, the male buckle includes an integrally formed male buckle mounting piece and an insert, the male buckle mounting piece includes a male buckle mounting base plate and a reinforcement piece arranged on the male buckle mounting base plate, and a guide head is provided at the end of the insert, and a strip groove is opened on the guide head.

[0010] Furthermore, a plurality of reinforcing grooves are provided on the upper surface of the reinforcing member, reinforcing walls are provided between the reinforcing grooves, and male buckle reinforcing ribs are provided on the side surfaces of the reinforcing member.

[0011] 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.

[0012] Furthermore, a female buckle reinforcement rib is provided on the outer surface of the locking sleeve surrounding the locking sleeve.

[0013] 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.

[0014] Furthermore, the male buckle and the female buckle are respectively made of hard materials.

[0015] The beneficial effects of the utility model are:

[0016] The anti-counterfeiting buckle of the utility model is provided with a built-in elastic locking member and locking teeth on the inner wall of the female buckle, which cooperate with the locking grooves and rack segments respectively provided on both sides of the male buckle to be inserted into the female buckle for locking. When the male buckle is inserted into the female buckle until the elastic locking member is buckled into the locking groove, the elastic locking member can no longer exit the locking groove in any direction. At this time, the elastic locking member transmits the elastic force to the male buckle through contact with the locking groove under the action of its own elasticity, so that the rack segment on the other side of the male buckle and the locking teeth on the female buckle can mesh and lock together; the anti-counterfeiting buckle A limit block is provided in the lock groove for stably locking the elastic lock piece that is buckled into the lock groove therein without displacement or shaking. At the same time, densely distributed meshing teeth are provided on the rack segment on the other side. When the meshing teeth are engaged with the lock teeth, the fitting clearance between the two is extremely small, and almost no relative displacement occurs. The combination of the locking methods on both sides makes the anti-counterfeiting buckle significantly more stable than the existing technology. There will be no shaking between the box cover and the box base, which 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.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0031] This utility model is a highly stable anti-counterfeiting buckle for packaging boxes, mainly used for anti-counterfeiting of wine packaging boxes. It has the characteristics of seamless fit and no room for shaking after locking. After the buckle is completed, it can prevent counterfeiters from inserting their fingers through the shaking gap to pry open the anti-counterfeiting buckle. The buckle is more secure and stable, and the safety and anti-counterfeiting performance are also significantly improved. Specifically, the utility model can be implemented as follows:

[0032] Example 1

[0033] This embodiment is a basic implementation plan of the anti-counterfeiting buckle of the utility model. Please refer to Figures 1-4 The anti-counterfeiting buckle as a whole can be composed of two parts, namely the male buckle 1 part for insertion and locking, and the female buckle 2 part 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 base of the packaging box, preferably installed inside the packaging box.

[0034] The elastic locking member 201 can cooperate with the concave locking groove 101 on the male buckle 1. When the male buckle 1 is initially inserted into the female buckle 2, the elastic locking member 201 deforms under a certain elasticity to leave a position 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 201 will be buckled into the locking groove 101. Since the locking groove 101 is concave, the elastic locking member 201 is partially buckled into it. The contact surface of the buckle will be hidden in the locking groove 101, and the elastic locking member 201 will be elastically buckled under the action of the elasticity. The locking member 201 will fit into the locking groove 101 under the condition of elastic pre-tightening force. At this time, if you want to penetrate the elastic locking member 201 into the locking groove 101 through the gap of the external packaging, you need to bend it at multiple large angles, which greatly increases the difficulty of counterfeiting. The locking groove 101 is provided with a limit block 102 to stably lock the elastic locking member 201 in the locking groove 101 without displacement or shaking, so that the male buckle 1 and the female buckle 2 will not move relative to each other.

[0035] When the elastic locking member 201 is buckled into the locking groove 101, the locking teeth 202 on the inner wall of the female buckle 2 will also engage with the rack segment 103 provided on the male buckle 1 at the same time. The tooth tip of the locking tooth 202 can be set as an acute-angled tooth, and the rack segment 103 is provided with densely arranged small meshing teeth, so that the fitting clearance between the locking tooth 202 and the rack segment 103 is extremely small, and it can be locked at any position of the rack segment 103. Similarly, since the locking surface of the locking tooth 202 and the rack segment 103 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 201 will squeeze the male buckle 1 to one side of the locking tooth 202, so that the locking tooth 202 and the rack segment 103 are more tightly engaged, thereby further improving the stability and security of the fastening, and completing the fastening of the entire anti-counterfeiting buckle.

[0036] The anti-counterfeiting buckle structure of this embodiment hides the buckling contact parts on both sides inside the lock groove 101 and the rack segment 103 of the male buckle 1 respectively, and after buckling, there is almost no relative movement space between the male buckle 1 and the female buckle 2 that can loosen or shake. The fit is tight, and it is difficult to shake the box cover and the box base apart from the outside, so there is no gap to pry the male buckle 1 and the female buckle 2 apart, and the overall stability is stronger and the anti-counterfeiting performance is better.

[0037] Example 2

[0038] This example is a further implementation plan based on Example 1. Please refer to Figure 4 、 Figure 5 and Figure 7 In order to better limit the movement of the male buckle 1 during insertion and avoid the difficulty in grasping the insertion distance after the male buckle 1 is inserted into the female buckle 2, this embodiment provides a limiting section 104 on one side of the locking groove 101 on the male buckle 1. The limiting section 104 is arranged in a sloped shape, which is convenient for guiding and dispersing the stress direction when contacted and reducing the contact strength. An end face limiting member 203 is provided on the end face of the female buckle 2 opposite to the limiting section 104. The end face limiting member 203 is used to cooperate with the limiting section 104 for limiting, so that after the male buckle 1 is inserted to a certain depth of the female buckle 2, the rear face limiting member 203 contacts the limiting section 104 for limiting and guiding the unloading force at the same time, thereby achieving the control of the insertion depth of the male buckle 1 within a reasonable range.

[0039] Example 3

[0040] This example is a further implementation plan based on Example 1. Please refer to Figure 4 、 Figure 7 and Figure 8 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 105 and an inserting part 106. The male buckle mounting part 105 does not enter the female buckle 2, and the male buckle mounting base 1051 is fixedly connected to the inner wall of the packaging box to provide support for the movement of the male buckle 1, and the reinforcement part 1052 is connected between the male buckle mounting base 1051 and the inserting part 106 to ensure the installation strength of the male buckle mounting part 105 and the connection strength at the position between the male buckle mounting base 1051 and the inserting part 106; a plurality of reinforcement grooves are provided on the upper surface of the reinforcement part 1052, and reinforcement walls are provided between the reinforcement grooves. Male buckle reinforcement ribs 109 are provided on the side of the reinforcement part 1052. The reinforcement part 1052 is further improved in strength through the support of the reinforcement wall and the setting of the male buckle reinforcement ribs 109, and the thickness and other dimensions are increased, which further improves the stability and effectively prevents violent damage.

[0041] To facilitate the insertion of the male buckle 1, a guide head 107 is provided on the end of the insert 106 on the male buckle 1 that is inserted into the female buckle 2. The guide head 107 can be set to a cone shape to facilitate the insertion of the insert 106, and during the insertion process, the elastic locking part 201 is guided and squeezed to make it elastically deformed, providing space for the insertion of the male buckle 1 until the elastic locking part 201 is buckled into the locking groove 101, and the guide head 107 completes the guiding function; the strip groove 108 on the guide head 107 can reduce the use of materials while ensuring the strength of the male buckle 1, making the anti-counterfeiting buckle lighter, easier to transport and saving costs.

[0042] 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.

[0043] Example 4

[0044] This example is a further implementation plan based on Example 1. Please refer to Figure 5 、 Figure 9 and Figure 10 In order to support the stable installation between the female buckle 2 and the packaging box, the female buckle 2 is provided with a female buckle mounting base 204 and a locking sleeve 205. The female buckle mounting base 204 is used to be fixedly connected to the inner wall of the packaging box to provide support for the fastening of the female buckle 2 and the male buckle 1, while the locking sleeve 205 is provided with an elastic locking member 201 and a locking tooth 202 for inserting and fastening the male buckle 1, thereby realizing the locking and anti-counterfeiting function of the anti-counterfeiting buckle;

[0045] The male buckle 1 and the female buckle 2 are specifically installed on the box lid or the box base 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 box lid and box base, the male buckle 1 can be set on the box base, and the female buckle 2 can be set on the inner wall of the box lid. The anti-counterfeiting buckle can be assembled together by aligning the female buckle 2 of the box lid with the male buckle 1 of the box base and inserting them into the box. The connection method between the anti-counterfeiting buckle and the packaging box can be gluing with an embedded structure. Those skilled in the art can make a choice according to actual needs.

[0046] Example 5

[0047] This embodiment is a further implementation plan based on the embodiment. In order to further improve the overall strength of the anti-counterfeiting buckle after assembly and prevent counterfeiters from physically damaging the anti-counterfeiting buckle to obtain a complete packaging box, this embodiment provides a female buckle reinforcement rib 206 around the lock buckle sleeve 205 to improve the stress strength that the anti-counterfeiting buckle can withstand. The female buckle reinforcement rib 206 is provided as a strip structure around the outer surface of the lock buckle sleeve 205 to achieve the effect of improving strength. Its distribution only needs to avoid the opening position of the elastic lock fastener 201. For example, Figure 5 and Figure 10 As shown in FIG, the female buckle reinforcement rib 206 at the position corresponding to the elastic locking member 201 is configured as a symmetrical structure separated on both sides, while the rest of the structure is configured as a surrounding integrated connection structure. The addition of the female buckle reinforcement rib 206 can further increase the stress tolerance of the anti-counterfeiting buckle and prevent it from being physically damaged.

[0048] Example 6

[0049] This example is a further implementation plan based on the example, please refer to Figure 4 In order to further improve the fastening stability between the elastic locking member 201 and the locking groove 101 and to hide the fastening surface in a position that is difficult to be touched through a more optimized shape structure, the elastic locking member 201 is configured as a hook shape in this embodiment, such as Figure 4 As shown, the hook-type elastic locking member 201 does not use its hook shape to hook the locking groove 101 to achieve locking, but provides elastic deformation ability through the hook shape, and engages with the locking groove 101 through the back of the hook of the hook-shaped part; preferably, the two adjacent outer walls of the elastic locking member 201 are at right angles to each other, and the shape of the locking groove 101 is also correspondingly set to a square groove with a vertical angle to match the vertical part of the elastic locking member 201. 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 201 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 201. Therefore, setting it to a vertical angle can achieve the best hiding of the locking surface while ensuring a good stress distribution.

[0050] Example 7

[0051] This embodiment is a further implementation plan based on the embodiment. 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 member 201 and strengthen 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 member 201 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 member 201 from breaking during the insertion process, which makes the packaging anti-counterfeiting ineffective.

[0052] 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.
