[0032] Embodiment 1:

[0033] This embodiment provides a waterproof packing box, including:

[0034] The outer box body 1 includes a box body main body 11 and a box cover 12 provided on the top of the box body main body 11. First positioning holes 4 are provided at the corners of the bottom of the box body main body 11, and positioning grooves 5 are provided at the corners of the box cover 12 and are located above the first positioning holes 4.

[0035] The tray 2 includes a first plate body 21 provided on the outer bottom of the outer box body 1, a second plate body 22 connected below the first plate body 21, and a plurality of support rods 23 provided on the top of the first plate body 21.

[0036] Wherein, a jack 6 is formed between the first plate body 21 and the second plate body 22 by a connecting portion. The support rods 23 pass through the first positioning holes 4, and the support rods 23 abut against two side walls at the corners inside the outer box body 1. The top ends of the support rods 23 are inserted into the positioning grooves 5. A limiting plate 24 is provided at the bottom end of the support rods 23, and the limiting plate 24 abuts against the inner bottom of the outer box body 1.

[0037] In this technical solution, the outer box body 1 can be made of corrugated cardboard, and a waterproof film made of plastic material can be covered on the outer surface of the corrugated cardboard, so that the outer box body 1 has the effects of waterproofing and wear resistance. The outer box body 1 can be a cuboid or a polygonal columnar structure with more than four side walls.

[0038] The box cover 12 and the box body main body 11 can be separated from each other, and the positioning grooves 5 on the box cover 12 and the first positioning holes 4 on the box body main body 11 are both adapted to the shape of the top of the support rods 23.

[0039] The support rods 23 can be fixedly connected to the top of the first plate body 21, or can be clamped or threadedly connected to the top of the first plate body 21. The support rods 23 are perpendicular to the upper surface of the first plate body 21.

[0040] When installing the packing box, place the tray 2 horizontally on a plane, align the first positioning holes 4 of the outer box body 1 with the support rods 23 and insert them downward, so that the bottom surface of the outer box body 1 abuts against the upper surface of the first plate body 21, the sides of the support rods 23 abut against two adjacent side surfaces at the corners of the box body main body 11, and the top of the support rods 23 can be flush with the top of the box body main body 11.

[0041] Subsequently, install the limiting plate 24. The limiting plate 24 and the support rods 23 can be fixedly connected by screws. The limiting plate 24 is used to prevent the outer box body 1 from detaching from the tray 2, improve the connection stability between the tray 2 and the box body main body 11, and at the same time prevent the outer box body 1 from moving up and down. The limiting plate 24 is detachable, which is convenient for detaching the outer box body 1 from the tray 2 for classified recycling.

[0042] Finally, cover the box cover 12 so that the top end of the support rod 23 is inserted into the positioning groove 5. The positioning groove 5 is used to further limit the position of the support rod 23, improve the stability of the support rod 23, and prevent the support rod 23 from shaking within the box body 11 under the action of external forces.

[0043] The support rod 23 can improve the structural strength of the outer box 1, enabling the outer box 1 to resist forces from the side and the vertical direction, thereby reducing the deformation of the outer box 1 caused by external collisions, or the deformation of the outer box 1 caused by the pressure exerted by heavy objects on the side and top of the outer box 1, and further causing damage to the goods inside the outer box 1.

[0044] The tray 2 can be made of wood or plastic. Usually, the packing box is directly placed on a horizontal surface, or multiple packing boxes are stacked into multiple layers. Since the surface of the packing box is smooth, it is not convenient to handle.

[0045] In this embodiment, under the condition that the tray 2 is provided at the bottom of the outer box 1, it can ensure the stacking of multiple packing boxes. Among them, the second plate body 22 can increase the bottom area of the tray 2 and improve the stability during stacking. When it is necessary to move the outer box 1, for heavier goods, a forklift can insert the fork into the jack 6 formed between the first plate body 21 and the second plate body 22. For lighter goods, a person can insert a finger into the jack 6 to carry it, or use two rod-shaped tools to insert into the jack 6 to lift it, which is convenient for handling the packing box.

[0046] Among them, the jack 6 can penetrate both sides of the tray 2. The jack 6 can be provided on the left and right sides and the front and back sides of the tray 2, facilitating the handling of the packing box at the front, back, left, and right positions of the outer box 1.
