[0019] Please see Figure 1-3This utility model provides a technical solution for a foldable paper packaging box: it includes a rear box panel 1, a rectangular groove 12 and a flap 13. The right side of the rear box panel 1 is connected to a right side panel 3 and a front box panel 4 in sequence. The left side of the rear box panel 1 is provided with a left side panel 5. The top and bottom of the rear box panel 1 are respectively provided with a box cover 2 and a bottom plate 6. The rear box panel 1, box cover 2, right side panel 3, front box panel 4, left side panel 5 and bottom plate 6 are folded into a packaging box. One side of the box cover 2 is provided with a locking protrusion 11. A through rectangular groove 12 is opened in the middle of the locking protrusion 11. The top center of the front box panel 4 is provided with a protruding flap 13. One side of the flap 13 is provided with an arc-shaped cardboard 14. The two ends of the arc-shaped cardboard 14 are fixedly connected to the two sides of the flap 13. The middle of the arc-shaped cardboard 14 is fixedly connected to the outer side of the front box panel 4.
[0020] Specifically, inclined protrusions 8 are provided on both sides of the bottom of the base plate 6 and on the side near the front box plate 4. Inclined grooves 9 are provided on the bottom of the right side plate 3, the left side plate 5 and the side of the front box plate 4 that contacts the base plate 6. The inclined protrusions 8 on the base plate 6 are respectively inserted into the corresponding inclined grooves 9.
