[0043] Embodiment 1

[0044] like Figure 1 -3 shows a double-sliding buckle anti-counterfeiting structure for a packaging box, which is mainly arranged between the box body 100 and the box cover 200 of the packaging box for buckle fixing and anti-counterfeiting. The double-sliding buckle anti-counterfeiting structure includes a base plate 1, a main buckle 2, and a plug buckle 3; the base plate 1 is fixed on the side wall of the box body or as a part of the inner plate of the box body, the main buckle 2 is plugged into the base plate 1, and the plug buckle 3 is fixed on the inner side wall of the box cover. When the box cover is completely covered on the box body, the plug buckle 3 on the inner side wall of the box cover is inserted into the base plate 1 to cooperate with the main buckle 2 to complete the buckle fixing and anti-counterfeiting of the box cover and the box body.

[0045] The base plate 1 is provided with a slot structure 11 and an arc-shaped slide groove 12, the upper end of the slot structure 11 is provided with an insertion opening 11a, the slot opening 12a of the arc-shaped slide groove 12 is located at the upper edge of the base plate 1, and the distance between the slot bottom 12b of the arc-shaped slide groove 12 and the slot structure 11 is smaller than the distance between the slot opening 12a of the arc-shaped slide groove 12 and the slot structure 11. The main buckle 2 can be inserted into the slot structure 11 from the insertion opening 11a of the slot structure 11, and the plug buckle 3 can slide into the arc-shaped slide groove 12 from the slot opening 12a of the arc-shaped slide groove 12.

[0046] Combination Figure 4 As shown, the slot structure 11 includes a pair of slot side plates 111 fixed on the same side of the base plate 1, the pair of slot side plates 111 are vertically arranged, the cross-section of the slot side plates 111 is L-shaped, and the pair of slot side plates 111 are enclosed on one side surface of the base plate 1 to form a slot with open upper and lower sides and an outward side.

[0047] like Figure 1 As shown in FIG. 3 , the main buckle 2 includes a pressing plate 21 and an inserting plate 22 integrally connected to the lower side of the pressing plate 21; the upper end surface of the base plate 1 is an inclined surface, and the pressing plate 21 is arranged parallel to the inclined surface of the upper end of the base plate 1. The shape of the inserting plate 22 is the same as that of the slot, and the inserting plate 22 can be inserted into the slide slot from top to bottom. When the inserting plate 22 is fully inserted into the slide slot, the lower end surface of the pressing plate 21 is just pressed on the upper end surface of the base plate 1, and a pair of slot side plates 111 block the side of the inserting plate 22 facing away from the base plate 1 to restrict the insertion direction of the inserting plate 22.

[0048] like Figure 1 As shown in FIG. 3 , the main buckle 2 also includes a spring sheet 23 integrally connected to the pressure plate 21 at one end. The spring sheet 23 is located on the side of the plug plate 22 close to the arc-shaped slide groove 12. There is a gap between the spring sheet 23 and the plug plate 22 to make the spring sheet 23 elastic. During the process of the main buckle 2 moving back and forth in the slot, the spring sheet 23 has a first state set away from the arc-shaped slide groove 12 and a second state set close to the arc-shaped slide groove 12; when the spring sheet 23 is in the second state set close to the arc-shaped slide groove 12, the spring sheet 23 forms a first non-return structure that allows the plug buckle 3 to slide into the arc-shaped slide groove 12 and prevents the plug buckle 3 from sliding out of the arc-shaped slide groove 12.

[0049] like Figure 1 As shown in FIG. 3 , the two opposite sides of the plug plate 22 are provided with a plurality of oblique teeth 221 arranged along the length direction thereof, and the side of the slot side plate 111 facing the slot is provided with a second non-return structure engaged with the oblique teeth 221. The second non-return structure allows the plug plate 22 to be inserted into the slot from the insertion port 11a and prevents the plug plate 22 from being moved out of the slot from the insertion port 11a. The oblique teeth 221 on the plug plate 22 are engaged with the second non-return structure on the slot side plate 111, which can prevent the main buckle 2 from retreating from the slide slot, thereby improving the reliability of the main buckle 2. In the first embodiment of the base plate 1, as shown in FIG. Figure 1 As shown in FIG. 3 , the second non-return structure is specifically a boss 112 disposed on the slot side plate 111. In the second embodiment of the substrate 1, as shown in FIG. Figure 5 As shown, the second non-return structure is specifically the inverted teeth 113 provided on the slot side plate 111. In other alternative embodiments of the base plate 1, the second non-return structure can also be specifically the spring sheet 23 provided on the slot side plate 111, as long as the second non-return structure can be engaged with the oblique teeth 221 to form a non-return structure.

[0050] like Figure 1 As shown in FIG. 3 , the end of the spring piece 23 away from the pressure plate 21 has a spring piece tip 231 bent toward the arc-shaped slide groove 12. A slanted top block 13 is provided on the side of the slot structure 11 close to the arc-shaped slide groove 12; when the spring piece 23 is in the second state close to the arc-shaped slide groove 12, the slanted top block 13 presses against the spring piece 23 to bend and deform the spring piece 23 toward the side close to the arc-shaped slide groove 12. The provision of the slanted top block 13 facilitates the bending of the spring piece 23, which is beneficial to improving the reliability of the non-return effect formed between the spring piece 23 and the buckle 3.

[0051] like Figure 6As shown in FIG. 7 , the buckle 3 includes a bottom plate 31, a limit plate 32 and a slide post 33. The bottom plate 31 and the limit plate 32 are connected to opposite sides of the slide post 33. The bottom plate 31 is usually fixed to the inner wall of the box cover 200. The length of the slide post 33 matches the width of the arc-shaped slide groove 12. The slide post 33 is slidably connected to the arc-shaped slide groove 12. The bottom plate 31 and the limit plate 32 are respectively limited against the opposite sides of the base plate 1. In the first embodiment of the buckle 3, as shown in FIG. Figure 7 As shown, the limiting plate 32 is provided with a limiting portion 321 bent away from the bottom plate 31, and the spring piece 23 is limited against the limiting portion 321. Figure 8 As shown, tooth grooves 322 are provided on two opposite sides of the limiting plate 32 , and the spring piece 23 is limited against the tooth grooves 322 .

[0052] In the double-sliding buckle anti-counterfeiting structure for packaging boxes, during the production and transportation stage of the packaging box, the main buckle 2 is not fully inserted into the slot structure 11, and the spring piece 23 is in a first state away from the arc-shaped slide groove 12. At this time, the plug buckle 3 can move back and forth freely in the arc-shaped slide groove 12, which is convenient for the transportation of the packaging box on the production line before bottling, and the anti-counterfeiting structure is not easy to be locked due to accidental touch during the transportation of the packaging box; during the packaging stage of the packaging box, the main buckle 2 is pressed down to make the main buckle 2 inserted into the slot structure 11 to a certain depth, the main buckle 2 cannot be retracted, and the spring piece 23 is in a second state close to the arc-shaped slide groove 12, and the spring piece 23 extends in the direction of the arc-shaped slide groove 12, and the spring piece 23 forms a first non-return structure that can prevent the plug buckle 3 from sliding out of the arc-shaped slide groove 12, thereby realizing the anti-counterfeiting fixation of the plug buckle 3. This double-sliding buckle anti-counterfeiting structure is not only complex in structure, high in anti-counterfeiting complexity, and not easy to be easily copied; but also convenient for packaging and transportation of packaging boxes before bottling.

[0053] Embodiment 2

[0054] like Fig. 9 The double-sliding buckle anti-counterfeiting structure for a packaging box shown in 11 is different from the first embodiment in that the first non-return structure is specifically a locking plate 4, one end of which is rotatably connected to a slot side plate 111 near the arc-shaped slide groove 12, and the locking plate 4 is provided with a protrusion 41 extending into the slot on the side facing the slot, and a locking plate tip 42 is provided on the side facing away from the slot. When the plug plate 22 is inserted into the slot, the plug plate 22 pushes the protrusion 41 and the locking plate 4 to rotate toward the side near the arc-shaped slide groove 12, so that the locking plate tip 42 forms a first non-return structure that allows the plug buckle 3 to slide into the arc-shaped slide groove 12 and prevents the plug buckle 3 from sliding out of the arc-shaped slide groove 12. With such a configuration, a shorter locking plate 4 can be used to achieve the non-return effect on the plug buckle 3. Compared with the spring plate 23 of the first embodiment, the locking plate 4 is not easy to break due to force during use.

[0055] Furthermore, a non-return structure may be provided on the protrusion 41 , and the non-return structure engages with the oblique teeth 221 on the plug plate 22 to prevent the plug plate 22 from returning.

[0056] Embodiment 3

[0057] like Fig.12 The anti-counterfeiting packaging box shown in the figure comprises a box body 100 and a box cover 200 which is arranged on the box body 100, and a double sliding buckle anti-counterfeiting structure for the packaging box as shown in the above embodiment 1 or embodiment 2 is arranged between the box body 100 and the box cover 200. An inner lining plate is arranged inside the box body 100, a base plate 1 is the upper end part of the inner plate of the box body 100, a main buckle 2 is plugged into a slot structure 11 of the base plate 1, and a plug buckle 3 is fixed on the inner side wall of the box cover 200. During the packaging, production and transportation process of the anti-counterfeiting packaging box, the plug buckle 3 on the box cover 200 can be arbitrarily inserted and exited from the arc-shaped slide groove 12 of the main buckle 2, so that it is convenient to open the box cover 200 to put products into the box body 100 or take out unqualified products in the box body 100 during the production and transportation process of the packaging box, which is convenient for production. During the packaging stage of the anti-counterfeiting packaging box, the main buckle 2 is pressed down by hand or automated equipment. After the main buckle 2 is inserted downward to the preset position, the main buckle 2 cannot be withdrawn. The spring piece 23 on the main buckle 2 is elastically deformed by the inclined top block 13, and the spring piece 23 moves to a position close to the arc-shaped slide groove 12. Then the box cover 200 is closed, and when the plug buckle 3 on the box cover 200 is inserted into the arc-shaped slide groove 12, the plug buckle 3 is engaged by the spring piece 23 and cannot be withdrawn, thereby achieving the purpose of anti-counterfeiting of the packaging box.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
