[0043] Embodiment 1

[0044] This embodiment provides a paper cardboard, which can change its size based on the size of the cardboard body 10 to adapt to the packaging of products of different sizes. Figure 1 and Figure 2As shown, the paper cardboard is made of all paper, wherein the paper cardboard includes a cardboard body 10 and at least two extension components (unnumbered), and a first plug-in slot 11 is provided on at least two adjacent sides of the cardboard body 10; at least two extension components are arranged in a one-to-one correspondence with the first plug-in slot 11, and the extension component includes an extension cardboard 21, and the extension cardboard 21 includes an extension body 211 and a plug-in component 212 protruding from the extension body 211, the extension body 211 and the plug-in component 212 are fixedly connected or detachably connected, the extension body 211 is arranged at the same height as the cardboard body 10, and the plug-in component 212 is plugged into and matched with the first plug-in slot 11 on the corresponding side. Through the above arrangement, when the size of the product changes, the extension card board 21 of suitable size can be inserted into the first plug-in slot 11, and the plug-in component 212 can be quickly plugged into the first plug-in slot 11 to realize the connection between the extension body 211 and the card board body 10. Since the first plug-in slot 11 is opened on at least two sides of the card board body 10, the extension card board 21 can be plugged on at least two sides of the card board body 10 to realize the size adjustment of the card board body 10 in the length and width directions to adapt to the packaging of products of different sizes.

[0045] In this embodiment, Figure 1 As shown, the cardboard body 10 is rectangular, and the four sides of the cardboard body 10 are provided with first plug-in slots 11, and four extension components are provided. That is to say, the four sides of the cardboard body 10 can be plugged with the extension cardboard 21, which can increase the range of size adjustment on the one hand, and on the other hand, if the two sides of the cardboard body 10 are plugged with the extension cardboard 21 in one direction, the overall symmetry is better.

[0046] For example, Figure 2 As shown, when the plug-in component 212 is fully inserted into the first plug-in slot 11, the extension body 211 is in contact with the cardboard body 10, and the extension length is the size of the extension body 211 in the extension direction. When the size of the extension body 211 in the extension direction does not reach the packaging size of the product, since the cardboard is made of all paper, such as Figure 3 As shown, the extension card plate 21 is pulled outward for a certain distance, and part of the connector 212 is still connected to the first connector slot 11, which is equivalent to lengthening the extension length and making the size change more flexible.

[0047] Optionally, the plug connector 212 is plugged into the extension body 211. Through the above arrangement, the plug connector 212 and the extension body 211 are detachable. On the one hand, the two are manufactured separately, so that the plug connector 212 can be made harder to ensure the strength of the connection position between the extension body 211 and the card body 10. On the other hand, the plug-in depth of the plug connector 212 and the extension body 211 can also be adjusted. Figure 3 In other words, Figure 3On the basis of this, the connector 212 remains stationary and the extension body 211 is pulled outward, which can further expand the range of size adjustment; furthermore, the minimum value of the extended size can be changed by manufacturing connectors 212 with different extension direction sizes.

[0048] Alternatively, if Figure 4 and Figure 5 As shown, the extended body 211 includes a first support portion 2111, a first reinforcement portion 2112 and a first panel 2114 bonded sequentially from bottom to top, a first notch 21121 is provided on one side of the first reinforcement portion 2112, the first notch 21121, the first support portion 2111 and the first panel 2114 together form a second plug slot 2113, and the plug-in 212 is plugged into the second plug slot 2113. It is understandable that since the extended body 211 is made of paper, it is difficult to form a notch after integral molding. By setting a three-layer structure, the second plug slot 2113 is formed after bonding, which can ensure strength and facilitate assembly.

[0049] Alternatively, if Figure 4 and Figure 5 As shown, the first support portion 2111 includes a second panel 21111 and at least two first support legs 21112. The second panel 21111 is bonded to the side of the first reinforcement portion 2112 away from the first panel 2114. The at least two first support legs 21112 are arranged in sequence along the length direction of the second panel 21111, and the at least two first support legs 21112 are connected to the side of the second panel 21111 away from the first reinforcement portion 2112. Through the above arrangement, the arrangement of the first support legs 21112 can raise the height of the extended body 211, and the gap between adjacent first support legs 21112 plays a role in reducing weight.

[0050] Optionally, the interior of the first support leg 21112 and the first reinforcement part 2112 are both honeycomb-shaped, the first panel 2114 and the second panel 21111 are both corrugated panels, and the internal structure of the connector 212 is different from that of the first reinforcement part 2112. It can be understood that the honeycomb-shaped paper board has better compression resistance and can ensure that the extended body 211 can carry heavier products, but the honeycomb-shaped paper product has poor compression resistance, and the first panel 2114 and the second panel 21111 are required to ensure that the extended body 211 has a stable shape. Optionally, the connector 212 is a corrugated panel, which can ensure that it is not easily deformed by lateral force during insertion. In other embodiments, the connector 212 can also be other paper-made plate-like structures with stronger deformation resistance than the honeycomb panel, which is not limited here.

[0051] In another optional embodiment, the first reinforcing portion 2112 and the plug-in connector 212 may be integrally formed using a corrugated panel to ensure strength. The integral part is T-shaped.

[0052] Optionally, combined Figure 1 and Figure 6 The cardboard body 10 includes a second support portion 12, a second reinforcement portion 13 and a third panel 14 bonded sequentially from bottom to top, and third notches 131 are provided on four sides of the second reinforcement portion 13. The third notches 131, the second support portion 12 and the third panel 14 form a first insertion slot 11. It is understandable that since the cardboard body 10 is made of paper, it is difficult to form a slot after integral molding. By setting a three-layer structure, the first insertion slot 11 is formed after bonding, which can ensure strength and facilitate assembly.

[0053] Alternatively, if Figure 6 As shown, the second support portion 12 includes a fourth panel 121 and at least four second support legs 122. The fourth panel 121 is connected to the side of the second reinforcement portion 13 away from the third panel 14; the at least four second support legs 122 are all arranged on the side of the fourth panel 121 away from the second reinforcement portion 13, and four of the at least four second support legs 122 are respectively arranged at the four corners of the fourth panel 121. Through the above arrangement, the arrangement of the second support legs 122 can raise the height of the card body 10, and the gaps between adjacent second support legs 122 play a role in reducing weight. In this embodiment, a second support leg 122 is arranged at each of the four corners of the fourth panel 121, and a second support leg 122 is arranged at the middle of each side, and a total of eight second support legs 122 are arranged. In other embodiments, four, nine or more second support legs 122 can also be arranged, which is not limited here.

[0054] Optionally, the interior of the second support leg 122 and the second reinforcement part 13 are both honeycomb-shaped, and the second panel 21111 and the fourth panel 121 are both corrugated panels. It can be understood that the honeycomb-shaped paper board has good compression resistance and can ensure that the extended body 211 can carry heavier products, but the honeycomb-shaped paper product has poor compression resistance, and the second panel 21111 and the fourth panel 121 are needed to ensure that the cardboard body 10 has a stable appearance.

[0055] Embodiment 2

[0056] The scheme of this embodiment is substantially the same as that of the first embodiment, except that the extension assembly includes a plurality of extension card boards 21 (not shown), the plug-in connector 212 in the first extension card board 21 is plugged into the extension body 211, and the rear extension card board 21 is plugged into the front extension card board 21. It is understandable that a plurality of extension card boards 21 can be plugged into one side of the card board body 10 in sequence, and the adjustment of the plug-in depth of the plug-in connector 212 further expands the adjustment range of the size of the paper card board. On this basis, the sizes of the plurality of extension bodies 211 can be made consistent, and there is no need to manufacture extension bodies 211 of various sizes to meet products with different extension size requirements. For the production line, it is not easy to make mistakes in configuring parts.

[0057] Alternatively, if Figure 7 As shown, a second notch 21122 is formed on the side of the first reinforcement portion 2112 away from the first notch 21121. The second notch 21122, the first support portion 2111 and the first panel 2114 together form a third plug-in slot (not shown). The third plug-in slot is used for plugging the rear plug-in component 212. It can be understood that in the first embodiment, the first reinforcement portion 2112 is Figure 4 In the U-shape shown in FIG. 1 , in this embodiment, the first reinforcement portion 2112 is Figure 7 The I-beam shown in .

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
