[0012] To enable those skilled in the art to better understand the technical solution of the present utility model, the preferred implementation of the present utility model will be described below in conjunction with specific embodiments. However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0013] The present utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Embodiment 1

[0015] See Figure 1 and Figure 2 As shown, a corrugated cardboard involved in this embodiment includes a base paper 1 and a face paper 2. A corrugated paper 3 is provided between the face paper 2 and the base paper 1. A jack 4 penetrating the corrugated paper 3 in the height direction is provided on the corrugated paper 3. A paper sheet 5 is adaptively inserted into the jack 4. The height of the paper sheet 5 is equal to the height of the corrugated paper 3. One end of the paper sheet 5 is bonded to the base paper 1 and the other end is bonded to the face paper 2.

[0016] Furthermore, the jack 4 extends in a straight line.

[0017] In this implementation, by setting the jack 4 to extend in a straight line structure, the jack 4 is convenient to open, and it is also convenient for the processing and insertion of the paper sheet 5.

[0018] Embodiment 2

[0019] See Figure 1 and Figure 2 As shown, a corrugated cardboard involved in this embodiment includes a base paper 1 and a face paper 2. A corrugated paper 3 is provided between the face paper 2 and the base paper 1. A jack 4 penetrating the corrugated paper 3 in the height direction is provided on the corrugated paper 3. A paper sheet 5 is adaptively inserted into the jack 4. The height of the paper sheet 5 is equal to the height of the corrugated paper 3. One end of the paper sheet 5 is bonded to the base paper 1 and the other end is bonded to the face paper 2.

[0020] Furthermore, the jack 4 extends in a curve; the extension trajectory of the jack 4 is in a sine curve shape.

[0021] In this implementation, by setting the jack 4 to extend in a curve structure, the arrangement length of the jack 4 is extended, the connection area between the paper sheet 5 inserted into the jack and the base paper 1 and the face paper 2 is increased. While making the connection reliable, the anti-bending ability of the cardboard in the end face direction is enhanced.
