[0045] In order to better understand the application, the following will be described in conjunction with Figures 1 to 11 .

[0046] Figure 1 The exploded structure of the packaging box lock 10 is schematically shown. Figure 2 The exploded structure of the packaging box lock 10 is schematically shown. Figure 3 The structure of the packaging box lock 10 in the locked state is schematically shown. Figure 4 The partial cross-sectional structure of the packaging box lock 10 is schematically shown. Figure 5 The partial cross-sectional structure of the packaging box lock 10 is schematically shown.

[0047] Referring to Figures 1 to 5 , the application provides a packaging box lock 10, which comprises a socket assembly 20 and a plug assembly 30.

[0048] The insertion hole assembly 20 comprises an insertion hole 201, a locking tooth 202 and a hanging hole 203. The locking tooth 202 is arranged in the insertion hole 201. The insertion hole 201 is in communication with the hanging hole 203. Along the first direction X, the locking tooth 202 is provided with the hanging hole 203 on both sides. The first direction X is perpendicular to the axial direction Z of the insertion hole 201.

[0049] The insertion assembly 30 comprises a main body 31, an intermediate locking tongue 32 and an elastic hanging part 33. The intermediate locking tongue 32 and the elastic hanging part 33 are connected to the main body 31. Along the first direction X, the intermediate locking tongue 32 is provided with the elastic hanging part 33 on both sides. The intermediate locking tongue 32 and the elastic hanging part 33 are arranged in a spaced manner. The intermediate locking tongue 32 comprises a connecting tooth 321. The elastic hanging part 33 comprises a hook 331.

[0050] When the insertion hole assembly 20 and the insertion assembly 30 are locked into an integral structure, the intermediate locking tongue 32 and the elastic hanging part 33 are inserted into the insertion hole 201 along the axial direction Z of the insertion hole 201. The connecting tooth 321 is engaged with the locking tooth 202 to be locked. The hook 331 is inserted into the hanging hole 203.

[0051] In the embodiment, the locking tooth 202 protrudes from the hole wall of the insertion hole 201. The locking tooth 202 is located on the insertion path of the intermediate locking tongue 32. After the connecting tooth 321 is engaged with the locking tooth 202 to be locked, the connecting tooth 321 cannot be disengaged from the locking tooth 202. When an excessive pulling force is applied to the intermediate locking tongue 32 along the axial direction Z of the insertion hole 201, at least one of the connecting tooth 321 and the locking tooth 202 will be damaged. At this time, the connecting tooth 321 can be disengaged from the locking tooth 202. After at least one of the connecting tooth 321 and the locking tooth 202 is damaged, the connecting tooth 321 cannot be re-engaged with the locking tooth 202 to be locked, thereby ensuring that the packaging box lock 10 is a one-time use structure and cannot be used twice, achieving physical anti-counterfeiting.

[0052] During the process of inserting the intermediate locking tongue 32 and the elastic hanging part 33 into the insertion hole 201, before the hook 331 of the elastic hanging part 33 is aligned with the hanging hole 203, the elastic hanging part 33 is limited by the hole wall of the insertion hole 201, so that the elastic hanging part 33 is inclined towards the intermediate locking tongue 32. After the hook 331 is aligned with the hanging hole 203, the elastic hanging part 33 rebounds, and the hook 331 is inserted into the hanging hole 203. The hook 331 can hook the hole wall of the hanging hole 203. When the insertion assembly 30 is pulled along the axial direction Z of the insertion hole 201, the engagement area between the intermediate locking tongue 32 and the locking tooth 202 can exert a reverse resistance, and the hook 331 can also exert a reverse resistance. The elastic hanging part 33 can form a limiting constraint in the first direction X, so as to prevent the elastic hanging part 33 and the intermediate locking tongue 32 from shaking in the insertion hole 201 along the first direction X.

[0053] The packaging box lock 10 of the embodiment of the present application comprises a socket assembly 20 and a plug assembly 30 which are used in mutual plug-in cooperation. When the packaging box lock 10 is applied to a packaging box, the socket assembly 20 and the plug assembly 30 can be respectively arranged on the box body and the box cover. After the original products to be packaged are placed in the packaging box, the box cover is buckled with the box body, and the socket assembly 20 and the plug assembly 30 are mutually plugged in cooperation to be locked into an integral structure. When the socket assembly 20 and the plug assembly 30 are locked into an integral structure, the intermediate locking tongue 32 and the elastic hanging part 33 are inserted into the plug-in hole 201 along the axial direction Z of the plug-in hole 201, and the connecting tooth 321 is engaged and locked with the locking tooth part 202, and the hook 331 is inserted into the hanging hole 203 to realize hanging. After the connecting tooth 321 is engaged and locked with the locking tooth part 202, the connecting tooth 321 cannot be disengaged from the engagement state with the locking tooth part 202. If the connecting tooth 321 is disengaged from the engagement state with the locking tooth part 202 in a manner of destroying the structure of at least one of the connecting tooth 321 and the locking tooth part 202, the connecting tooth 321 cannot be re-engaged and locked with the locking tooth part 202, thereby ensuring that the packaging box lock 10 is a one-time use structure and cannot be used twice, realizing physical anti-counterfeiting, effectively reducing the possibility of the secondary use of the packaging box and the loading of non-original products in the packaging box and flowing into the market, and effectively protecting the reputation of the original manufacturer or the interests of consumers.

[0054] In some implementable manners, referring to FIG. 6, when the connecting tooth 321 is engaged and locked with the locking tooth part 202, the engagement interface formed by the connecting tooth 321 and the locking tooth part 202 can be perpendicular to the axial direction Z of the plug-in hole 201. Figure 5

[0055] In some implementable manners, the socket assembly 20 is an integrally formed structure. The socket assembly 20 can be a plastic structure or a metal structure. For example, the socket assembly 20 can be a metal structure including copper or steel. The plug assembly 30 is an integrally formed structure. The plug assembly 30 can be a plastic structure or a metal structure. For example, the plug assembly 30 can be a metal structure including copper or steel.

[0056] In some implementable manners, the plug-in hole 201 can be a through hole. Along the axial direction Z of the plug-in hole 201, the plug-in hole 201 has two openings. The hanging hole 203 can be a through hole. The hanging hole 203 has two openings.

[0057] In some implementable manners, referring to FIG. 6, when the connecting tooth 321 is engaged and locked with the locking tooth part 202, the engagement interface formed by the connecting tooth 321 and the locking tooth part 202 can be perpendicular to the axial direction Z of the plug-in hole 201. Figure 2 Figure 4 and Figure 5 ​​As shown, the two sets of locking teeth 202 are spaced apart along the second direction Y. The middle locking tongue 32 is provided with a connecting tooth 321 on each of the two sides along the second direction Y. The middle locking tongue 32 passes between the two sets of locking teeth 202. The connecting teeth 321 on the two sides are respectively engaged with the two sets of locking teeth 202. The first direction X is perpendicular to the second direction Y.

[0058] The two sets of locking teeth 202 can be respectively engaged with the connecting teeth 321 on the two sides of the middle locking tongue 32, thereby facilitating to improve the connecting strength of the locking teeth 202 and the middle locking tongue 32. Meanwhile, the two sets of locking teeth 202 can respectively limit the middle locking tongue 32 from the two sides of the middle locking tongue 32, so that the middle locking tongue 32 is not easy to shake along the second direction Y in the insertion hole 201.

[0059] In some examples, each set of locking teeth 202 can include one locking tooth 202 or more than two locking teeth 202. For example, each set of locking teeth 202 can include more than two locking teeth 202. The more than two locking teeth 202 are distributed along the axial direction Z of the insertion hole 201. Along the second direction Y, one or more than one connecting tooth 321 can be respectively provided on the surfaces on the two sides of the middle locking tongue 32.

[0060] In some implementable manners, referring to Figures 1 to 3 As shown, the insertion hole assembly 20 includes the plate body 21 and the frame body 22 connected with each other. The plate body 21 and the frame body 22 enclose the insertion hole 201. Along the second direction Y, the frame body 22 is located on one side of the plate body 21. The plate body 21 and the frame body 22 are respectively provided with the locking teeth 202. The frame body 22 is provided with the hanging hole 203.

[0061] The plate body 21 of the insertion hole assembly 20 can be used to connect with the box body of the packaging box. The plate body 21 of the insertion hole assembly 20 can be used as an adapter to connect with the box body of the packaging box. After the insertion hole assembly 20 is connected with the box body of the packaging box, the frame body 22 can protrude towards the accommodating cavity of the box body. The insertion hole assembly 20 including the plate body 21 and the frame body 22 facilitates to connect the insertion hole assembly 20 with the box body of the packaging box, thereby facilitating to reduce the connection difficulty of the insertion hole assembly 20 with the box body.

[0062] In some examples, the frame body 22 includes a recess. The plate body 21 covers the opening of the recess along the second direction Y. In the connected state of the frame body 22 and the plate body 21, the recess of the frame body 22 can form the insertion hole 201.

[0063] In some examples, the plate body 21 and the frame body 22 can be an integrally formed structure. The plate body 21 and the frame body 22 can be plastic structural members or metal structural members. For example, the plate body 21 and the frame body 22 can be metal structural members including copper or steel.

[0064] In some examples, referring to Figures 1 to 3 As shown, the frame body 22 includes a top plate 221. The plate body 21 and the top plate 221 are spaced apart along the second direction Y. The top plate 221 includes a through hole 2211 and an elastic cantilever 2212. The through hole 2211 is in communication with the insertion hole 201. The elastic cantilever 2212 is located in the through hole 2211. The elastic cantilever 2212 is provided with a locking tooth portion 202.

[0065] During the process of inserting the intermediate lock tongue 32 into the insertion hole 201, the intermediate lock tongue 32 can push the locking tooth portion 202 and the elastic cantilever 2212 to swing, so that the intermediate lock tongue 32 is relatively easy to be inserted to a predetermined position. When the intermediate lock tongue 32 is inserted to the predetermined position, the connecting tooth 321 of the intermediate lock tongue 32 engages and locks with the locking tooth portion 202.

[0066] In some examples, referring to Figures 1 to 3 As shown, the frame body 22 includes a side plate 222. The side plate 222 connects the top plate 221 and the plate body 21. Along the first direction X, two side plates 222 are spaced apart. The two side plates 222, the top plate 221 and the plate body 21 enclose to form the insertion hole 201. The two side plates 222 are each provided with a hanging hole 203. A part of the hanging hole 203 penetrates the side plate 222, and another part penetrates the top plate 221. A part of the hook 331 of the elastic hanging portion 33 can hook the side plate 222, and another part can hook the top plate 221.

[0067] The hook 331 of the elastic hanging portion 33 can be hung and matched with different positions on the frame body 22, so that a limiting constraint can be formed in different directions to reduce the possibility of the hook 331 being pulled out of the hanging hole 203 along the first direction X or the second direction Y.

[0068] After the elastic hanging portion 33 is inserted into the insertion hole 201 and inserted to a predetermined position, the hook 331 of the elastic hanging portion 33 is inserted into the hanging hole 203, and the elastic hanging portion 33 can abut against the side plate 222. Along the first direction X, the side plate 222 can form a limiting constraint on the elastic hanging portion 33, reducing the possibility of the elastic hanging portion 33 and the intermediate lock tongue 32 shaking along the first direction X in the insertion hole 201.

[0069] Exemplarily, the insertion hole assembly 20 includes two hanging holes 203. Along the first direction X, one hanging hole 203 is arranged on each side of the locking tooth portion 202.

[0070] In some examples, along the second direction Y, the orthographic projection area of the frame body 22 is smaller than the orthographic projection area of the plate body 21.

[0071] The jack assembly 20 can be connected to the box body of the packaging box through the plate body 21. The plate body 21 of the jack assembly 20 has a relatively large area, thereby facilitating to increase the connection area between the jack assembly 20 and the box body of the packaging box, to facilitate to improve the connection strength between the jack assembly 20 and the box body of the packaging box, and to reduce the possibility that the jack assembly 20 is separated from the box body of the packaging box due to accidental force.

[0072] The box body of the packaging box can be provided with a relief hole. The plate body 21 of the jack assembly 20 can be overlapped on the box body, and the frame body 22 can pass through the relief hole. The plate body 21 of the jack assembly 20 can play a positioning role, thereby facilitating to reduce the assembly difficulty of the jack assembly 20 and the box body.

[0073] Exemplarily, the orthographic projection of the frame body 22 is located within the orthographic projection of the plate body 21. Any position of the outer contour of the orthographic projection of the frame body 22 has a spacing with the outer contour of the orthographic projection of the plate body 21.

[0074] Exemplarily, the plate body 21 is a rectangular structure. Along the second direction Y, the surface of the plate body 21 away from the frame body 22 is a plane.

[0075] In some examples, referring to Figures 1 to 3 As shown, the plug-in assembly 30 further comprises a limiting part 34. The limiting part 34 is connected to the main body part 31. Along the first direction X, the limiting part 34 is arranged on the outer side away from the intermediate lock tongue 32 of the elastic hanging part 33. The limiting gap 301 is formed between the limiting part 34 and the elastic hanging part 33. When the jack assembly 20 and the plug-in assembly 30 are locked with each other, the side plate 222 is inserted into the limiting gap 301, and the limiting part 34 abuts against the side plate 222, and the main body part 31 abuts against the side plate 222.

[0076] When the main body part 31 abuts against the side plate 222, the intermediate lock tongue 32 and the elastic hanging part 33 are plugged into the predetermined positions. At this time, the connecting teeth 321 of the intermediate lock tongue 32 are engaged with the locking tooth part 202 to be locked, and the hook 331 is hung in the hanging hole 203.

[0077] When the plug-in assembly 30 and the jack assembly 20 are plugged with each other, the side plate 222 can be aligned through the limiting gap 301 to position the plug-in assembly 30, thereby facilitating to quickly and accurately plug the plug-in assembly 30 and the jack assembly 20, and improving the plug-in work efficiency. When the plug-in assembly 30 and the jack assembly 20 are locked with each other, along the first direction X, the side plate 222 can limit the limiting part 34 to form a limiting constraint, thereby facilitating to reduce the possibility that the limiting part 34, the elastic hanging part 33 and the intermediate lock tongue 32 shake along the first direction X.

[0078] Exemplarily, along the axial direction Z of the plug-in hole 201, the limiting part 34 is beyond the elastic hanging part 33 and the intermediate lock tongue 32, and the intermediate lock tongue 32 is beyond the elastic hanging part 33.

[0079] In some examples, referring to Figure 1 and Figure 3 , the outer surface of the side plate 222 opposite to the insertion hole 201 is provided with a convex rib 2221. The limiting portion 34 abuts against the convex rib 2221.

[0080] When the insertion assembly 30 and the insertion hole assembly 20 are inserted into each other, the contact area between the limiting portion 34 and the convex rib 2221 is relatively small, so that the frictional resistance between the limiting portion 34 and the convex rib 2221 is small, thereby facilitating to reduce the insertion resistance of the limiting portion 34, so that the limiting portion 34 can be relatively labor-saving inserted into the side plate 222, and the insertion difficulty of the limiting portion 34 and the side plate 222 is reduced.

[0081] In some examples, referring to Figure 1 and Figure 3 , the insertion assembly 30 further comprises a flange 35. The flange 35 is arranged on the side surface of the main body portion 31 and the limiting portion 34 respectively, away from the intermediate lock tongue 32.
