[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figures 1-6An embodiment of this utility model provides: a pull-out paper packaging box, including a box body 1, a plurality of first circular grooves 2 are provided on the bottom of the inner wall of the box body 1, and support rods 3 are provided on the plurality of first circular grooves 2. Four grooves 4 are provided on the bottom of the inner wall of the box body 1, and limiting grooves 5 are provided on both sides inside the grooves 4. Clamping components are provided inside the grooves 4. A first protective mechanism is provided on the top of the inner wall of the box body 1. A box cover 6 is provided on the top of the box body 1. A square groove 7 is opened on the top of the box cover 6. A second protective mechanism is provided on the square groove 7. A waterproof layer 18 is provided on one side of the box body 1, and a wear-resistant layer 19 is provided on one side of the waterproof layer 18.

[0035] Specifically, when the top and sides of the packaging box are impacted or squeezed, the reinforcing plate 9 and multiple support rods 3 can withstand part of the side force and support the sides of the main body of the cardboard box. At the same time, the square frame 12 and multiple connecting rods 14 can withstand part of the top force and support the top of the box lid 6. Meanwhile, the inflatable cushion 10 is set to provide buffer protection to prevent the box body 1 from being directly damaged by pressure or impact. The waterproof layer 18 is a waterproof plastic film, the wear-resistant layer 19 is coated paper, and the base plate 8, reinforcing plate 9, connecting rods 14 and support rods 3 are all solid paper structures.

[0036] The first protective mechanism includes a base plate 8 disposed on the top of the inner wall of the box 1, a reinforcing plate 9 disposed on one side of the base plate 8, a number of air cushions 10 disposed on the other side of the base plate 8, and a number of through holes 11 disposed on the bottom of the base plate 8.

[0037] The second protective mechanism includes a square frame 12 fixedly connected to the top of the square groove 7, a number of second circular grooves 13 are opened at the bottom of the square frame 12, and a number of connecting rods 14 are fixedly connected between the two sides of the inner wall of the square frame 12.

[0038] Specifically, by aligning the second circular groove 13 on the cover plate with the support rod 3 and inserting it into the support rod 3, the cover plate is fixed in place, thereby protecting the top of the items inside the packaging box. The second circular groove 13, the first circular groove 2, and the through hole 11 have the same diameter and are all matched with the support rod.

[0039] The clamping assembly includes a spring 15 fixedly connected to one side of the groove 4. One end of the spring 15 is fixedly connected to a clamping block 16. Limiting blocks 17 are provided on both sides of the clamping block 16. The limiting blocks 17 are adapted to the limiting groove 5. Anti-slip texture is provided on one side of the clamping block 16.

[0040] Specifically, the item is placed from top to bottom on the top of the inner wall of the box 1. At the same time, the clamping block 16 abuts against the item and moves, and the spring 15 is compressed. Thus, under the action of the clamping block 16 and the spring 15, the position of the item is limited and fixed. By setting anti-slip texture, friction can be increased to prevent the item from falling off the clamping block 16 when the transport is bumpy.

[0041] The two sides of the box body 1 are rotatably connected to a lifting handle 20, and the four corners of the bottom of the box body 1 are provided with support feet 21, and the bottom of the support feet 21 is provided with anti-slip pads 22.

[0042] Specifically, the lifting handle 20 can move the packaging box, and the support foot 21 can raise the bottom of the packaging box to prevent the bottom of the box 1 from directly contacting water and causing water to enter the bottom of the box 1.

[0043] Working principle: Before using the packaging box, several support rods 3 are inserted into the first circular groove 2 inside the box body 1. Then, the substrate 8 is inserted into the support rods 3 through the through hole 11 to limit the substrate 8, thus completing the work before using the packaging box.

[0044] Then, the item is placed from top to bottom on the top of the inner wall of the box 1. At the same time, the clamping block 16 abuts against the item and moves, and the spring 15 is compressed. Under the action of the clamping block 16 and the spring 15, the position of the item is limited and fixed. Then, the second circular groove 13 on the cover is aligned with the support rod 3 and inserted into the support rod 3 to complete the limiting and fixing of the cover, thus completing the use of the packaging box.

[0045] When the top and sides of the packaging box are impacted or squeezed, the reinforcing plate 9 and multiple support rods 3 can withstand part of the side force and support the sides of the main body of the cardboard box. At the same time, the square frame 12 and multiple connecting rods 14 can withstand part of the top force and support the top of the box lid 6. Meanwhile, the inflatable cushion 10 is set to provide buffer protection to prevent the box body 1 from being directly damaged by pressure or impact, thereby protecting the items inside the box body 1.
