[0002] At present, for products such as consumer electronics or luxury goods, packaging boxes are needed for packaging and positioning protection. Usually, the products are packed in boxes with detachable top and bottom or pizza boxes with folded sides. Because boxes with top and bottom or pizza boxes are easy to open, additional sealing stickers or heat shrink bags are needed to keep them closed to prevent products from being swapped or consumers from buying second-hand products.

[0003] However, the sealing sticker is very easy to tear due to its small bonding area, and after the heat shrink bag of the packaging box is removed, it is easy to re-shrunk and packaged through a heat shrink machine and a new heat shrink bag, making it difficult to achieve anti-tampering and anti-counterfeiting after the existing packaging box is provided with a sealing sticker and a heat shrink bag.

[0044] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0045] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0047] In the prior art, the structure of the packaging box is usually a top and bottom box type or a pizza box type with folded sides. In order to facilitate the removal of products in the packaging box, the top and bottom box type or pizza box type packaging box is generally easy to open. At the same time, in order to prevent the product from being tampered with by others before it reaches the hands of consumers, and to prevent the product in the packaging box from being replaced, it is necessary to add an additional packaging structure to the packaging box, such as adding an additional sealing sticker or heat shrink bag to the packaging box to keep it closed. However, due to the small bonding area between the sealing sticker and the box body, it is very easy to be torn apart, and after the heat shrink bag of the packaging box is disassembled, it is also easy to re-seal it with a heat shrink machine and a new heat shrink bag for heat shrink packaging, making it difficult to achieve anti-tampering and anti-counterfeiting after the existing packaging box is provided with a sealing sticker and a heat shrink bag.

[0048] In order to solve the problem that it is difficult to achieve tamper-proof packaging boxes in the prior art, Figure 1 and Figure 5As shown, this embodiment provides a packaging box, including an outer box 1 and an inner box 2 movably arranged in a accommodating cavity 10 of the outer box 1, and a connecting component 3 is connected between the outer box 1 and the inner box 2; the connecting component 3 is configured so that when the inner box 2 is pulled out from the outer box 1 to a first set distance, the fixed connection between the connecting component 3 and the outer box 1 is separated; when the inner box 2 is retracted into the outer box 1, the connecting component 3 maintains an active connection with the outer box 1.

[0049] The present application forms the packaging box of the present application through an outer box 1, an inner box 2 and a connecting component 3, wherein the inner box 2 is movably arranged in the accommodating cavity 10 of the outer box 1, and a connecting component 3 is connected between the outer box 1 and the inner box 2. When the inner box 2 has not been extracted from the outer box 1, one end of the connecting component 3 remains fixedly connected to the outer box 1. When the inner box 2 is extracted from the outer box 1 to a first set distance, the fixed connection between the connecting component 3 and the outer box 1 is separated, however, when the inner box 2 is retracted into the outer box 1, the connecting component 3 and the outer box 1 remain in a movable connection and cannot be restored to a fixedly connected state. The user only needs to observe or feel whether the fixed connection between the connecting component 3 and the outer box 1 still exists to determine whether the packaging box has been opened. Compared with the anti-tampering method of using a sealing sticker or a heat shrink bag in the prior art, the packaging box of the present application is difficult to restore the fixed connection between the connecting component 3 and the outer box 1, which can play an anti-tampering and anti-counterfeiting effect.

[0050] In particular, refer to Figure 1 The outer box 1 includes an end plate 12 and a plurality of wall plates 11. The plurality of wall plates 11 enclose the end plate 12 to form a receiving cavity 10. A limiting cavity 111 is arranged in the wall plate 11. The limiting cavity 111 is arranged at a distance from the receiving cavity 10. The wall plate 11 includes a first plate body 112 and a second plate body 113. The first plate body 112 and the second plate body 113 are respectively arranged on both sides of the limiting cavity 111. The first plate body 112 is provided with a positioning hole 114, and the second plate body 113 is provided with a limiting hole 115.

[0051] The inner box 2 is provided with a receiving groove 20 for receiving the product on any one side of the cavity wall or cavity bottom close to the receiving cavity 10;

[0052] The connection assembly 3 is arranged in the limiting cavity 111, and includes a limiting block 31 and a flexible connection member 32. The limiting block 31 is fixedly connected to a first end 321 of the flexible connection member 32, and a second end 322 of the flexible connection member 32 which is away from the first end 321 passes through the limiting hole 115 and is fixedly connected to the inner box 2. The limiting block 31 is detachably connected to the positioning hole 114;

[0053] When the inner box 2 is pulled out from the outer box 1, the flexible connector 32 fixed to the inner box 2 through the second end 322 drives the limit block 31 to disengage from the positioning hole 114 and enter the limit cavity 111; when the inner box 2 is retracted into the outer box 1, the limit block 31 remains in the limit cavity 111.

[0054] In this embodiment, the packaging box of the present application is formed by an outer box 1, an inner box 2 and a connecting assembly 3, wherein the outer box 1 includes an end plate 12 and a plurality of wall plates 11, and the end plate 12 is enclosed by a plurality of wall plates 11 to form a receiving cavity 10 capable of receiving the inner box 2, and any side of the inner box 2 close to the cavity wall or cavity bottom of the receiving cavity 10 is concavely provided with a receiving groove 20 for receiving the product, so that the inner box 2 drawn out from the receiving cavity 10 can be retracted into the receiving cavity 10 of the outer box 1 after placing and receiving the product, and the receiving groove 20 is wrapped and protected by the outer box 1. Moreover, a limiting cavity 111 is concavely provided in the wall plate 11, so that the limiting cavity 111 is spaced apart from the receiving cavity 10, and the connecting assembly 3 can be received through the limiting cavity 111. Correspondingly, the wall plate 11 includes a first plate body 112 and a second plate body 113 , which are respectively arranged on both sides of the limiting cavity 111 . The first plate body 112 is provided with a positioning hole 114 , and the second plate body 113 is provided with a limiting hole 115 .

[0055] As for the connection mode of the connection component 3 with the outer box 1 and the inner box 2, the connection component 3 includes a limit block 31 and a flexible connector 32. The limit block 31 is fixed to the first end 321 of the flexible connector 32, and the second end 322 of the flexible connector 32, which is away from the first end 321, passes through the limit hole 115 and is fixedly connected to the inner box 2. The limit block 31 is detachably connected to the positioning hole 114 of the outer box 1. When the inner box 2 needs to be pulled out from the outer box 1, the flexible connector 32 fixed to the inner box 2 through the second end 322 drives the limit block 31 to move. As the inner box 2 moves away from the outer box 1 in the pulling direction, the limit block 31 is separated from the positioning hole 114 and enters the limit cavity 111. When the inner box 2 is retracted into the outer box 1 again, since the flexible connector 32 can be deformed in the limiting cavity 111, the limiting block 31 remains in the limiting cavity 111. Even if the inner box 2 is repeatedly pulled relative to the outer box 1, the limiting block 31 cannot be reset to the positioning hole 114.

[0056] Compared with the anti-tampering method using sealing stickers or heat shrink bags in the prior art, the packaging box of this embodiment can determine whether the packaging box has been opened by simply observing whether there is a limit block 31 in the positioning hole 114, thereby achieving anti-tampering and anti-counterfeiting effects.

[0057] Specifically, when the packaging box of the present application is used, if the inner box 2 is located in the accommodating cavity 10 of the outer box 1 and the limiting block 31 is kept in the positioning hole 114 (such as Figure 3 If there is no stopper 31 in the positioning hole 114, even if the inner box 2 is in the accommodating cavity 10 of the outer box 1, it can be determined that the packaging box has been opened, and the product in the inner box 2 may be used or replaced, which has the effect of preventing tampering and anti-counterfeiting.

[0058] For the manufacturing and assembly method of the packaging box in the present application, the outer box 1 and the inner box 2 can be integrally formed by injection molding, respectively. As for the connecting component 3, conventional cardboard or plastic board can be used as the limit block 31, and a rope or chain can be used as the flexible connector 32. Before the inner box 2 is inserted into the accommodating cavity 10 of the outer box 1, a deformable slender object such as an iron wire is first inserted from the positioning hole 114 into the limit hole 115, and then the second end 322 of the flexible connector 32 of the connecting component 3 is connected to the end of the slender object. The flexible connector 32 and the limit block 31 are driven to move by pulling the slender object, so that the second end 322 of the flexible connector 32 is inserted from the positioning hole 114 into the limit hole 115 by threading the needle, until the limit block 31 is just clamped in the positioning hole 114, and the second end 322 of the flexible connector 32 is located in the accommodating cavity 10. In this embodiment, part of the stop block 31 can be inserted into the positioning hole 114 and reach the positioning cavity 111, and the posture of the stop block 31 in the positioning hole 114 and the positioning cavity 111 can be adjusted, for example, after the stop block 31 is completely inserted into the positioning cavity 111, the stop block 31 is pulled to snap into the positioning hole 114, so that the stop block 31 can be installed in the positioning hole 114. For the second end 322 of the flexible connector 32, the second end 322 of the flexible connector 32 can be temporarily fixed to the cavity wall of the accommodating cavity 10 by tape or a clip, and then the inner box 2 containing the product is inserted into the accommodating cavity 10. Before the inner box 2 is fully inserted into the accommodating cavity 10, the second end 322 of the temporarily fixed flexible connector 32 is fixed to the inner box 2, for example, double-sided tape is set on the second end 322 or on the inner box 2, and the second end 322 is bonded and fixed to the inner box 2 by driving the inner box 2 close to the second end 322. Then, the inner box 2 is driven to be fully inserted into the accommodating cavity 10, so that the packaging box completes the wrapping protection of the product and also completes the installation of the outer box 1, the connecting component 3 and the inner box 2.

[0059] In order to reduce the manufacturing cost of the outer box 1, preferably, reference Figure 6 and Fig.10, multiple wall panels 11 and end panels 12 are directly spliced ​​and assembled to form the outer box 1, and there is no need to use the injection molding process to generate multiple wall panels 11 and end panels 12, which reduces the use of injection molds and injection materials, and also reduces the injection molding process, thereby reducing the manufacturing cost. In this embodiment, the end panel 12 and multiple wall panels 11 can be produced separately and then assembled and fixed, or they can be divided and cut on a plate to form the end panel 12 and multiple wall panels 11 respectively, and then the end panel 12 and multiple wall panels 11 are folded and spliced ​​according to adjacent edge lines, and the outer box 1 can also be quickly assembled. It should be noted that a connecting auxiliary plate 13 can be provided between the end panel 12 and the wall panel 11 or between the wall panels 11 that need to be spliced, and the connecting auxiliary plate 13 can be integrally formed with the edge of one of the end panels 12 or the wall panels 11, so that when two adjacent end panels 12 and the wall panels 11 or two adjacent wall panels 11 and the wall panels 11 are folded, the two adjacent end panels 12 and the wall panels 11 or two adjacent wall panels 11 and the wall panels 11 can be spliced ​​by the connecting auxiliary plate 13.

[0060] In a preferred embodiment, reference Fig. 9 The wall panel 11 includes a first plate body 112, a connecting plate 116, and a second plate body 113 which are stacked, wherein the connecting plate 116 is provided with a connecting hole 1161, and the first plate body 112, the hole wall of the connecting hole 1161, and the second plate body 113 can enclose a limiting cavity 111. In this embodiment, the wall panel 11 is disassembled to form a streamlined first plate body 112, a connecting plate 116, and a second plate body 113, so that the first plate body 112, the connecting plate 116, and the second plate body 113 can be manufactured separately, so that the wall panel 11 does not need to be manufactured by an injection molding process, and the processing and manufacturing cost of the packaging box is further reduced. Moreover, before stacking and assembling the first plate 112, the connecting plate 116 and the second plate 113 and fixing them, it is only necessary to set the limit block 31 of the connecting assembly 3 in the positioning hole 114 of the first plate 112, and also set the flexible connector 32 in the connecting hole 1161 of the connecting plate 116, and then cover the second plate 113 on the connecting plate 116, so that the second end 322 of the flexible connector 32 passes through the limiting hole 115 of the second plate 113, and then the wall plate 11 with the connecting assembly 3 installed can be formed, thereby improving the installation efficiency of the connecting assembly 3 and the wall plate 11. It should be noted that, in the two wall plates 11, the second plate 113 is close to the center of the accommodating cavity 10 of the outer box 1, while the first plate 112 is away from the center of the accommodating cavity 10, so that the positioning holes 114 of the two wall plates 11 are both outside the outer box 1, and the two limiting holes 115 are located inside the outer box 1.

[0061] Preferably, some of the wall panels 11 may include a first plate body 112, a connecting plate 116 and a second plate body 113, and the remaining wall panels 11 may be integral plates. The first plate body 112, the connecting plate 116 and the second plate body 113 of some of the wall panels 11 may all be made of cardboard to facilitate stacking and assembly. Correspondingly, the remaining wall panels 11 and the end panels 12 may also be made of cardboard, and the edges of the wall panels 11 or the end panels 12 may be provided with connecting auxiliary plates 13 made of cardboard, so that multiple wall panels 11 and end panels 12 can be folded and assembled to form a box body. More preferably, refer to Fig.10 , two first plates 112, two wall plates 11 and one end plate 12 can be arranged in a splicing order, and the two first plates 112, two wall plates 11 and one end plate 12 before splicing can be obtained by cutting a cardboard. After the first plate 112 is spliced ​​with the remaining wall plates 11 or the end plates 12 to form a prototype of the outer box 1 with the accommodating cavity 10, the second plate 113 and the connecting plate 116 are fixed with the first plate 112 in the accommodating cavity 10, so as to assemble and form a complete outer box 1. Similarly, the second plate 113 can also be arranged at the edge of the remaining wall plates 11 or the end plates 12 in a splicing order until the second plate 113 is spliced ​​with the remaining wall plates 11 and the end plates 12, and then the first plate 112 and the connecting plate 116 are fixedly arranged on the outside of the second plate 113, so as to assemble and form the outer box 1. In order to facilitate the splicing of the first plate body 112 or the second plate body 113 with the remaining wall panels 11 and the end panels 12, a connecting auxiliary plate 13 can be set at the edges of the first plate body 112, the second plate body 113, the remaining wall panels 11 or the end panels 12 to increase the connection area between the first plate body 112, the second plate body 113, the remaining wall panels 11 and the end panels 12 during the splicing process, thereby increasing the connection strength.

[0062] For the connection method of the first plate 112, the connecting plate 116 and the second plate 113, a rivet can be directly passed through the first plate 112, the connecting plate 116 and the second plate 113 to form a fixed connection. Fig. 9The wall panel 11 also includes a connecting layer 117. The connecting layer 117 is arranged between the first plate body 112 and the connecting plate 116 and between the connecting plate 116 and the second plate body 113. Under the premise that the first plate body 112, the connecting plate 116 and the second plate body 113 are not damaged by installing rivets, the first plate body 112, the connecting plate 116 and the second plate body 113 are stably fixedly connected through the connecting layer 117, so that the assembled wall panel 11 is beautiful and simple, and the assembly efficiency of the wall panel 11 is also improved. In this embodiment, the connecting layer 117 can be a double-sided adhesive or a quick-drying adhesive. Since the bonding area between the first plate body 112, the connecting plate 116 and the second plate body 113 is large, the first plate body 112, the connecting plate 116 and the second plate body 113 are difficult to be torn apart. Even if they are forcibly torn apart, traces will be left, which can also play the role of judging whether they are forcibly demolished.

[0063] In order to further reduce the forced tearing and separation of the first plate 112, the connecting plate 116 and the second plate 113, preferably, the first plate 112 can be arranged on the edge of the remaining wall panels 11 or the end panels 12 in a splicing order, so that after the first plate 112 is spliced ​​with the remaining wall panels 11 and the end panels 12, a prototype of the outer box 1 with the accommodating cavity 10 is formed, and then the second plate 113 and the connecting plate 116 are fixed to the first plate 112 in the accommodating cavity 10 through the connecting layer 117. Fig.10 Since the outer box 1 prototype is formed by folding and assembling the first plate 112 and the other wall panels 11, there is an integrated connection structure between the first plate 112 and the adjacent wall panels 11, making it difficult to separate the first plate 112 from the adjacent wall panels 11. Fig. 9 At this time, the second plate body 113 and the connecting plate 116 are fixed on the side of the first plate body 112 close to the accommodating cavity 10 in the accommodating cavity 10. Under the cover of the connecting structure between the first plate body 112 and the remaining wall panels 11, the difficulty of tearing open the first plate body 112, the connecting plate 116 and the second plate body 113 is increased, and the anti-tampering effect is further improved.

[0064] In a preferred embodiment, reference Fig.12 The wall plate 11 also includes a connecting portion 118 disposed between the positioning hole 114 and the limiting block 31. The connecting portion 118 is used to limit the connection between the positioning hole 114 and the limiting block 31, so as to prevent the limiting block 31 from accidentally falling from the positioning hole 114 due to the bumping of the packaging box during transportation, thereby affecting the anti-tampering judgment result. The connecting portion 118 can be an elastic limiting ring, or a block and buckle structure disposed on the edge of the positioning hole 114 and the edge of the limiting block 31. Preferably, reference Figure 3The connecting portion 118 can be a dotted line structure arranged on the first plate body 112 at the edge position corresponding to the positioning hole 114, and the limit block 31 is a plate structure circled by the dotted line structure on the first plate body 112. By pressing the limit block 31, the dotted line structure can be destroyed so that the limit block 31 is separated from the first plate body 112, and at the same time, the hole circled by the dotted line structure also forms the positioning hole 114.

[0065] When the connection portion 118 is provided between the positioning hole 114 and the limiting block 31, the inner box 2 cannot be directly withdrawn from the outer box 1 under the limiting effect of the connection portion 118 on the limiting block 31. Before opening the packaging box of the present application, it is necessary to release the limiting effect of the connection portion 118 on the limiting block 31 and the positioning hole 114, for example, by pressing the limiting block 31 into the limiting cavity 111, so that the inner box 2 can be withdrawn relative to the outer box 1.

[0066] In another embodiment, reference Fig.11 A first guiding structure 41 is provided on the side of the edge of the positioning hole 114 close to the direction in which the inner box 2 is pulled out, so that when the inner box 2 is pulled out relative to the outer box 1, the first guiding structure 41 can guide the limiting block 31 from the positioning hole 114 into the limiting cavity 111. Under the guidance of the first guiding structure 41, the interference between the limiting block 31 and the positioning hole 114 can be reduced, so that the inner box 2 can be quickly pulled out relative to the outer box 1.

[0067] Further, refer to Fig.11 A second guide structure 42 is provided on one side of the limit block 31 close to the direction in which the inner box 2 is pulled out. The mutual guiding effect of the first guide structure 41 and the second guide structure 42 can further reduce the interference between the limit block 31 and the positioning hole 114, and further improve the efficiency of pulling out the inner box 2 relative to the outer box 1. In this embodiment, the first guide structure 41 and the second guide structure 42 can be smooth curved surfaces or inclined surfaces, which are not specifically limited in this embodiment.

[0068] Preferably, reference Fig.11 The inclined surface of the second guide structure 42 can continue to extend toward the limiting cavity 111 to form a stop portion 43, and the limiting block 31 can enter the limiting cavity 111 along the top inclined surface of the second guide structure 42 and the stop portion 43. When the limiting block 31 completely passes over the stop portion 43, the stop portion 43 can prevent the limiting block 31 from returning to the positioning hole 114, which can further prevent tampering.

[0069] For the preferred structure of the connection assembly 3, refer to Figure 7The connection assembly 3 further includes a fixing plate 33, one side surface of the fixing plate 33 is fixed to the second end 322 of the flexible connector 32, and the other side surface of the fixing plate 33 is fixedly connected to the inner box 2. Since the fixing plate 33 fixed to the end of the flexible connector 32 increases the connection area with the inner box 2, the flexible connector 32 is fixedly connected to the inner box 2 through the fixing plate 33, and the connection strength between the flexible connector 32 and the inner box 2 can be increased. In this embodiment, it is only necessary to fix the second end 322 and the inner box 2 respectively through any two side surfaces of the fixing plate 33, and the two side surfaces can be adjacent or opposite, which is not specifically limited in this embodiment.

[0070] Preferably, reference Figure 8 , the inner box 2 is concavely provided with a connection groove 21, and the fixing plate 33 is fixed in the connection groove 21. On the one hand, the connection between the fixing plate 33 and the inner box 2 can be guided and positioned, and on the other hand, the surface of the fixing plate 33 can be flush with the surface of the inner box 2, which has the effect of hiding the fixing plate 33 and avoiding the interference between the fixing plate 33 and the limiting hole 115. More preferably, the shape of the connection groove 21 corresponds to the contour shape of the fixing plate 33, so that the fixing plate 33 fits the shape of the connection groove 21, and the fixing plate 33 is further hidden in the connection groove 21.

[0071] Further, refer to Figure 8 , an adhesive layer 22 is provided in the connection groove 21, and the fixing plate 33 and the connection groove 21 are fixedly connected by the adhesive layer 22, so as to further improve the connection strength between the fixing plate 33 and the connection groove 21. The adhesive layer 22 can be provided at the groove bottom of the connection groove 21, or at the groove wall of the connection groove 21, and of course, can also be provided at the groove bottom and the groove wall of the connection groove 21 at the same time, so as to connect and fix the fixing plate 33 and the connection groove 21 at multiple positions.

[0072] In another embodiment, the color of the stopper 31 is different from the color of the outer box 1, so that the stopper 31 can be distinguished from the outer box 1, so as to quickly determine whether the stopper 31 exists in the positioning hole 114 of the outer box 1, thereby quickly knowing whether the package box has been opened. Alternatively, the texture of the stopper 31 can be different from the texture of the outer box 1, so that the stopper 31 can be distinguished from the outer box 1, and the effect of quickly knowing whether it has been tampered with and preliminary anti-counterfeiting can also be achieved.

[0073] Specifically, the colors of the limit block 31 and the outer box 1 can be two colors with high contrast, such as blue and red, yellow and black, etc. As for the textures of the limit block 31 and the outer box 1, the texture directions or texture styles of the two can be set differently, which is also convenient for distinguishing the limit hole 115 and the outer box 1.

[0074] In particular, refer to Figure 2 and Figure 4The second plate 113 is provided with an observation hole 119, and the observation hole 119 is arranged corresponding to the positioning hole 114. When the inner box 2 is pulled out from the outer box 1, the pulling-out state of the inner box 2 can be checked through the observation hole 119. Moreover, the observation hole 119 can also connect the inside of the accommodating chamber 10 with the atmosphere, so as to avoid the problem that the inner box 2 is too tightly connected to the cavity opening of the accommodating chamber 10 to form an air pressure difference, which makes it difficult to pull the inner box 2 out of the outer box 1.

[0075] In addition, when the first guide structure 41 and the second guide structure 42 are respectively provided on the positioning hole 114 and the limiting block 31, the mutual guiding and limiting of the first guide structure 41 and the second guide structure 42 may prevent the limiting block 31 from being directly installed in the positioning hole 114. At this time, the size of the observation hole 119 is made larger than or equal to the limiting block 31, and the limiting block 31 is installed in the positioning hole 114 through the observation hole 119. This can prevent the limiting block 31 from falling out of the positioning hole 114 and facilitate the installation of the limiting block 31 in the positioning hole 114.

[0076] In another embodiment, a light-transmitting shielding plate (not shown in the figure) may be provided on the side of the first plate 112 away from the second plate 113. The shielding plate covers the positioning hole 114, thereby preventing the limit block 31 from falling out of the positioning hole 114 and allowing the connection state of the limit block 31 and the positioning hole 114 to be observed. The shielding plate and the first plate 112 may be fixedly connected by strong adhesive, and even if the shielding plate is violently torn off, the first plate 112 will be damaged, and the user can know that the packaging box may have been opened, thereby achieving the same anti-tampering and anti-counterfeiting effects.

[0077] Optionally, when the inner box 2 continues to move to the second set distance relative to the outer box 1, the connecting component 3 is engaged with the outer box 1 to limit the inner box 2 from continuing to move relative to the outer box 1. This embodiment can prevent the inner box 2 from being completely withdrawn from the outer box 1 by the engagement limit between the connecting component 3 and the outer box 1, and can prevent the inner box 2 from directly falling out when the outer box 1 is taken out, thereby reducing the damage caused by the falling of the product and providing indirect protection for the product. In addition, maintaining the connection between the inner box 2 and the outer box 1 can also prevent the outer box 1 from being lost. When the packaging box is needed again to protect the product, the original outer box 1 can be used to wrap and protect the inner box 2, thereby extending the service life of the packaging box.

[0078] Preferably, the width of the limit block 31 is larger than the aperture of the limit hole 115, so that when the inner box 2 is pulled out relative to the outer box 1, the limit block 31 moves in the limit cavity 111 until the limit block 31 reaches the position of the limit hole 115 and is blocked by the limit hole 115, thereby preventing the inner box 2 from continuing to be pulled out relative to the outer box 1. By correspondingly setting the length of the flexible connector 32 and the distance between the limit hole 115 and the positioning hole 114, the pull-out distance of the inner box 2 relative to the outer box 1 can be limited. For example, the pull-out distance of the inner box 2 is set to just expose the receiving groove 20 of the inner box 2 to take and place the product, and keep a part of the inner box 2 in the receiving cavity 10 of the outer box 1, so as to facilitate the retraction of the inner box 2 into the outer box 1.

[0079] The present application may use a packaging box alone to package and wrap the product for protection, or may additionally provide a packaging bag or packaging box to contain the packaging box, thereby providing secondary packaging and protection for the product in the packaging box, which is not specifically limited in this embodiment.
