[0002] Porcelain is a fragile product. When using cartons for transportation and storage, it is often necessary to stuff a lot of flexible fillers into the cartons to prevent the porcelain from being damaged. However, cartons may be damaged during transportation, or accidentally fall after being stacked. These factors can easily cause the items inside to break, especially for precious porcelain such as items produced by special techniques and antiques. Once damaged, the economic losses caused are huge. Commonly used cartons are thin, have low protection capabilities, and poor stability when stacked. In view of this, the inventor made a new invention. Utility Model Content

DETAILED DESCRIPTION

[0016] The following is combined with Figures 1 to 4 The utility model is described in detail.

[0017] The utility model discloses a thickened cardboard box that can be positioned and stacked, comprising a box body 1, wherein symmetrical first cover plates 11 are arranged on the top and bottom of the box body 1 in a first direction, symmetrical second cover plates 12 are arranged on the top and bottom of the box body 1 in a second direction, limiting slide grooves 13 are arranged on four corners inside the box body 1, the first cover plate 11 and the second cover plate 12 are arranged on the first and second cover plates 12, a positioning opening 14 corresponding to the limiting slide grooves 13 is arranged inside the box body 1, a lifting and lowering inner shell body 2 is arranged, limiting sliders 21 cooperating with the limiting slide grooves 13 are arranged on the four corners of the inner shell body 2, a positioning block 22 that can pass through the positioning opening 14 is arranged on the bottom of the limiting slider 21, window portions a15 are arranged on two opposite sides of the box body 1, window portions b23 are arranged on two sides of the inner shell body 2 corresponding to the window portions a15, a limiting strip 24 is extended outward from the top of the window portion b23, and the limiting strip 24 can move up and down in the window portion a15. When cartons are stacked, the positioning block 22 in the upper carton can pass through the positioning opening 14 at the bottom of the carton and be inserted into the positioning opening 14 at the top of the lower carton, so that the two cartons are positioned and stacked, which can prevent the cartons from shaking and moving. The limit bar 24 moves up and down in the window portion a15, so the movable range of the inner shell 2 is limited by the window portion a15. When the limit bar 24 is at the top of the window portion a15, the inner shell 2 is in an upper position inside the box 1, and the window portion b23 is interconnected with the window portion a15, which is convenient for the transporter to move the carton; when the limit bar 24 is at the bottom of the window portion a15, the inner shell 2 is in a lower position inside the box 1, and the positioning block 22 extends from the positioning port 14 below the box 1, which is convenient for plugging and positioning with the positioning port 14 at the top of other boxes 1. At the same time, the window portion b23 is staggered with the window portion a15, and the inner shell 2 blocks the window portion a15, which can be convenient for reminding the transporter that the carton is in a positioned and stacked state, avoiding direct movement and damage to individual components. The inner shell 2 can be quickly moved by the limit bar 24, which is simple to operate and easy to use.

[0018] In the present invention, the box body 1, the first cover plate 11, and the second cover plate 12 all have a certain thickness, specifically, Figure 2 As shown:

[0019] The shell of the box body 1 is composed of an outer corrugated layer 3, a first positioning layer 4 and an inner corrugated layer 5. The first positioning layer 4 is made of plastic material, and the buffering and protective performance of the inner and outer surfaces of the box body 1 is high.

[0020] The first cover plate 11 is composed of an outer corrugated layer 3, a second positioning layer 6 and an inner corrugated layer 5, and a connecting belt 61 is provided between the second positioning layer 6 and the first positioning layer 4. The second positioning layer 6 and the connecting belt 61 are both made of plastic material, and this structure makes the first cover plate 11 not easy to be torn, and has high protection capability and durability.

[0021] The width of the first cover plate 11 is greater than that of the second cover plate 12. In this solution, when packaging the carton, the second cover plate 12 is first covered, and then the first cover plate 11 is covered, so that the second cover plate 12 is hidden inside. The second cover plate 12 is made of pure corrugated paper and has a lower hardness than the first cover plate 11. It can separate the first cover plate 11 from the objects inside the box body 1, and further protect the objects inside the box body 1.

[0022] A step portion 16 is provided at the connection between the box body 1 and the second cover plate 12. The second cover plate 12 has a certain thickness. When the second cover plate 12 is normally covered, the connection between the second cover plate 12 and the box body 1 will be squeezed against each other, so that the second cover plate 12 cannot be smoothly covered. The box body 1 is partially cut downward to form the step portion 16. The step portion 16 provides an accommodating space at the connection between the box body 1 and the second cover plate 12. When the second cover plate 12 is covered, the step portion 16 abuts against the bottom of the second cover plate 12, so that the second cover plate 12 can be smoothly covered at the upper and lower ends of the box body 1.

[0023] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
