Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example 1:

fig. 1 shows a connecting structure between paper boards, which is used for connecting a first paper board 1 and a second paper board 2, and comprises a tongue piece 3 connected with a crease at the edge of the first paper board 1, a blocking piece cutting seam 4 arranged on the convex edge of the second paper board 2, a blocking piece crease 5 arranged on the convex edge of the second paper board 2, and a locking seam 6 arranged at two ends of the blocking piece crease 5; the flap slit 4 and the flap fold 5 enclose on the second sheet 2 and form a bullet-proof flap 7 which can be turned around the flap fold 5.

Wherein, the length of tongue piece 3 is 5cm, and the width is 2cm, and 2 fore shaft kerfs 6's length is 0.5cm, and the distance between 2 fore shaft kerfs 6's outer end is 5.2cm to the both sides apex angle circular arc transition of tongue piece 3 is in order to insert in the fore shaft kerfs 6.
