[0005] Preferably, the bottom plate, the side plates, the cover plate, the top plate, the partition plate and the plug-in structure are formed by folding a piece of cardboard.

[0006] Preferably, the plug-in structure includes a plug-in board arranged on the top of the cover plate, a plug-in interface 1 is provided on the plug-in board, a gap 1 for inserting the plug-in board is provided between the top plate and the partition plate, and a plug-in interface 2 is provided on the top of the two partition plates. The plug-in interface 1 and the two plug-in interfaces 2 are plugged into each other to fix the cover plate.

[0007] Preferably, the plug-in structure includes an insert block arranged on the top of the cover plate, a gap 2 for inserting the insert block is arranged between the top plate and the partition plate, and a plug-in interface 3 is opened on the top of the two partition plates.

[0008] Preferably, a covering plate is connected to the partition plate and is used to surround the opening between the side plate and the partition plate.

[0009] Preferably, both the front and rear sides of the side plate are connected with limit plates, and the length of the limit plates is greater than the distance between the side plate and the partition plate.

[0010] Preferably, a notch is provided on the top plate, and the notch is located above the second plug interface.

[0011] Preferably, observation windows are provided on the top plate and the partition plate.

[0012] The beneficial effects of the utility model are as follows: the top plate is divided into two parts, a partition is connected to the top plate, and the product is separated from the middle by the partition during packaging. Thus, when designing the sponge lining, one side plate can be omitted, the volume of the sponge lining can be reduced, the required thickness of the cardboard is smaller, the overall volume can be reduced, and the cardboard is more environmentally friendly than sponge.

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] See also Figure 1-Figure 3 The utility model provides a packaging box, including a bottom plate 1, two side plates 2 and two cover plates 3, the two side plates 2 are connected to the left and right sides of the bottom plate 1, the two cover plates 3 are connected to the front and back sides of the bottom plate 1, and also includes two top plates 4, the two top plates 4 are respectively connected to the tops of the two side plates 2, and a downwardly extending partition plate 5 is connected to the side of the top plate 4 away from the side plate 2, the partition plate 5 separates the space inside the packaging box, and a plug-in structure is arranged on the cover plate 3 and the partition plate 5.

[0018] The top plate 4 is divided into two pieces, and a partition 5 is connected to the top plate 4. When packaging, the product is separated from the middle by the partition 5. In this way, when designing the sponge lining, one side plate 2 can be omitted, thereby reducing the volume of the sponge lining. The required thickness of the cardboard is smaller, and the overall volume can be reduced. Compared with sponge, cardboard is more environmentally friendly.

[0019] Furthermore, the bottom plate 1, the side plate 2, the cover plate 3, the top plate 4, the partition plate 5 and the plug-in structure are folded from a piece of cardboard, so that the overall structure is more solid, the processing steps are reduced, less waste paper is generated, and energy conservation and environmental protection are achieved.

[0020] As a first embodiment, the plug-in structure includes a plug-in board 6 arranged on the top of the cover plate 3, a plug-in interface 71 is arranged on the plug-in board 6, a gap 1 for inserting the plug-in board 6 is arranged between the top plate 4 and the partition plate 5, and a plug-in interface 72 is opened on the top of the two partition plates 5. The plug-in interface 71 and the two plug-in interfaces 72 are plugged into each other to fix the cover plate 3.

[0021] When connecting, the plug board 6 is inserted into the gap 1 to increase the strength of the cover plate 3 after it is covered; through the cooperation of the plug interface 1 71 and the plug interface 2 72, the cover plate 3 and the partition plate 5 are positioned and locked, making the overall structure more solid.

[0022] As a second embodiment, the plug-in structure includes an insert block arranged on the top of the cover plate 3 , a gap 2 for inserting the insert block is arranged between the top plate 4 and the partition plate 5 , and a plug-in interface 3 73 is opened on the top of the two partition plates 5 .

[0023] When connected, the plug block passes through the second slit and the third plug port 73 to lock the cover plate 3, which has a simple structure and is easy to manufacture.

[0024] Furthermore, a covering plate 8 for surrounding the opening between the side plate 2 and the partition plate 5 is connected to the partition plate 5 .

[0025] By setting the covering plate 8, after the side plates 2, the top plate 4 and the partition plate 5 are covered, the covering plate 8 is separated between the inner liner and the cover plate 3, thereby increasing the positioning performance of the inner liner and playing a protective role.

[0026] Furthermore, both the front and rear sides of the side plate 2 are connected with limit plates 9 , and the length of the limit plates 9 is greater than the distance between the side plate 2 and the partition plate 5 .

[0027] After the limiting plates 9 are further added, the two limiting plates 9 cross-limit the inner lining and the covering plate 8, making the overall structure more solid.

[0028] Furthermore, a notch 41 is formed on the top plate 4 , and the notch 41 is located above the second plug-in interface 72 .

[0029] The setting of the notch 41, in the first embodiment, facilitates the operator to insert the plug board 6 into the first gap, and can partially expose the second plug interface 72, so as to facilitate the alignment and plugging of the first plug interface 71 and the second plug interface 72. In the second embodiment, it is convenient to insert the plug block into the second gap.

[0030] Furthermore, observation windows 10 are provided on the top plate 4 and the partition plate 5 to facilitate observation of the packaging status and timely detection of problems before packaging is completed.
