[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, the present utility model discloses a shock-proof plastic packaging box, which includes an outer box body 1 hinged with a box cover 6. An inner box body 2 is arranged in the inner cavity of the outer box body 1. A reinforcing bump 3 is integrally connected to the inner side wall of the outer box body 1. A reinforcing block 5 is integrally connected to the inner side wall of the inner box body 2. A positioning groove 4 corresponding to the reinforcing block 5 is formed on the outer side wall of the inner box body 2. The reinforcing bump 3 is inserted into the positioning groove 4. A connecting rib 10 is connected between adjacent reinforcing blocks 5 on the inner side wall of the inner box body 2.

[0021] A reinforcing rib 11 adjacent to its inner side wall is integrally connected to the bottom inner wall of the outer box body 1.

[0022] Specifically, a side groove 7 corresponding to the reinforcing bump 3 is formed on the outer side wall of the outer box body 1.

[0023] In this embodiment, the shapes of the reinforcing bump 3, the side groove 7, the reinforcing block 5, and the positioning groove 4 are all trapezoidal.

[0024] The side groove 7 arches towards the inner cavity of the outer box body 1 to form the reinforcing bump 3, and the positioning groove 4 arches towards the inner cavity of the inner box body 2 to form the reinforcing block 5.

[0025] Specifically, both ends of one side of the top of the outer box body 1 far from its hinge point with the box cover 6 are connected with buckle blocks 8, and buckle grooves 9 cooperating with the buckle blocks 8 are formed on the box cover 6.

[0026] In this embodiment, when the outer box body 1 is connected to the box cover 6, the buckle blocks 8 are snapped into the buckle grooves 9.

[0027] Specifically, a reinforcing cushion block 13 is integrally connected to the bottom of the outer box body 1. At least two bottom bumps 12 are integrally connected to the bottom inner wall of the outer box body 1. A connecting groove into which the bottom bumps 12 can be inserted is formed at the bottom of the inner box body 2. A bottom groove 14 corresponding to the bottom bumps 12 is formed at the bottom of the reinforcing cushion block 13.

[0028] In this embodiment, the bottom groove 14 arches towards the inner cavity of the outer box body 1 to form the bottom bumps 12.

[0029] When the outer box body 1 is connected to the inner box body 2, the bottom bumps 12 are inserted into the connecting groove at the bottom of the inner box body 2.

[0030] Specifically, a sealing groove 15 is formed at the top end of the inner cavity of the outer box body 1. A U-shaped block 16 is fixedly connected to the top inner wall of the sealing groove 15.
