DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 of the embodiments.

[0031] Please refer to Figures 1 to 7A packaging carton with adjustable internal space includes a box body 1, on which a closing wing 2 is arranged. After loading is completed, the closing wing 2 only needs to be folded to a corresponding position and then sealed with tools such as tape.

[0032] A moving plate 9 is slidably mounted inside the box 1, and fixed blocks 10 are fixedly mounted on both sides of the moving plate 9, and a sliding block 11 is fixedly mounted on the fixed block 10. A sliding groove 5 for the sliding block 11 to slide is provided at a corresponding position of the box 1;

[0033] Through the cooperation of the slider 11 and the slide groove 5, the movable plate 9 can be moved inside the box 1. The distance between the two movable plates 9 is the space available for loading items, and targeted regulation can be performed according to actual needs.

[0034] A lifting plate 12 is slidably installed inside the movable plate 9, and limit rods 13 are fixedly installed on both sides of the lifting plate 12. The limit rods 13 are exposed from the fixed block 10. Two fixed plates 7 are fixedly installed inside the box body 1, and limit holes 8 are evenly and equidistantly provided on the fixed plates 7.

[0035] The limiting hole 8 is matched with the limiting rod 13. By making the limiting hole 8 inside the limiting rod 13, the movable plate 9 cannot be moved, thereby ensuring the stability of the position of the movable plate 9 and preventing unexpected displacement due to changes in the external environment. This ensures that the loaded items will not shake, thereby ensuring stability during transportation.

[0036] The lifting plate 12 is provided with a pulling assembly and a resetting assembly.

[0037] When adjustment is needed, it is only necessary to pull the assembly to move the lifting plate 12 upwards, so that the limiting rod 13 can move upwards synchronously, and then the limiting rod 13 is disengaged from the limiting hole 8, so that the movable plate 9 can be moved, which is convenient for adjustment and makes the adjustment simpler and more convenient, and is easy to use.

[0038] The reset assembly can ensure that the limiting hole 8 of the limiting rod 13 is stably located inside when no external force is applied.

[0039] The pulling assembly includes a connecting rod 14 , which is fixedly mounted on the lifting plate 12 , and one end of the connecting rod 14 away from the lifting plate 12 is exposed to the movable plate 9 on which the operating plate 3 is fixedly mounted.

[0040] By raising the operating plate 3 , the lifting plate 12 can be raised by the driving action of the connecting rod 14 , thereby completing the disengagement of the limiting rod 13 and the limiting hole 8 .

[0041] The reset component includes a fixed cylinder 15 which is fixedly installed inside the moving plate 9. A sliding column 16 is slidably installed on the fixed cylinder 15. A spring 17 is fixedly installed inside the fixed cylinder 15, and the other end of the spring 17 is fixedly installed on the sliding column 16.

[0042] When the lifting plate 12 rises, the sliding column 16 moves into the fixed cylinder 15, and thus the spring 17 is compressed. When reaching the designated position, the force applied to the lifting plate 12 is cancelled, and then under the action of the elastic force, the lifting plate 12 automatically descends, and then the limiting rod 13 enters into the corresponding limiting hole 8 to complete the limiting activity.

[0043] The number of the reset components is two, and they are respectively located on both sides of the lifting plate 12.

[0044] The existence of the reset component enables the lifting plate 12 to stably perform ascending or descending activities in the vertical direction, ensuring the stability of the operation of the lifting plate 12 and the limiting rod 13.

[0045] The box body 1 is provided with taking slots 6 at the ends of the two sliding grooves 5. The taking slots 6 are communicated with the sliding grooves 5, and the taking slots 6 can expose the slider 11 completely.

[0046] The number of the moving plates 9 can be increased or decreased through the taking slots 6, so that the number of the taking slots 6 can be adjusted pertinently according to actual needs, with stronger applicability and more convenient use.

[0047] In the limited state, the operating plate 3 is at the same height as the upper surface of the box body 1. In the closed state, the closing wing 2 is in direct contact with the operating plate 3. Since the packing boxes are generally stacked during transportation, on the one hand, under the action of gravity, the operating plate 3 cannot move, which can ensure that the limiting rod 13 is stably located inside the limiting hole 8 to ensure the limiting effect. On the other hand, the fixing plate 7 can be used as the X-axis support, and the operating plate 3 and the devices at its bottom can be used as the Y-axis and Z-axis supports to ensure that the packing box will not be excessively deformed due to external extrusion, affecting the normal use of the internal items.

[0048] Air bags 4 are inlaid and installed on both the front and rear sides of the moving plate 9. The existence of the air bags 4 can further improve the protection effect on the items inside the box body 1, and can be inflated and deflated to control its volume.

[0049] The working process of the present utility model: First, adjust the number of the moving plates 9 pertinently through the taking slots 6 according to actual needs, and then adjust the distance between adjacent ones pertinently according to the size of the items.

[0050] By raising the operation panel 3, driven by the connecting rod 14, the lifting plate 12 can be raised, thus completing the separation activity between the limit rod 13 and the limit hole 8. At this time, the sliding column 16 moves into the fixed cylinder 15, and then the spring 17 is compressed.

[0051] After that, through the cooperation of the slider 11 and the chute 5, the moving plate 9 can be moved inside the box body 1. When the required position is reached, the force applied to the lifting plate 12 is cancelled. Then, under the action of the elastic force, the lifting plate 12 can automatically descend, and then the limit rod 13 enters into the corresponding limit hole 8 to complete the limiting activity.

[0052] At this time, the item is stably located between the two positions. According to the actual required volume, the airbag 4 can be inflated. After all the goods are placed and loaded, only need to fold the closing wing 2 to the corresponding position, and then use tools such as adhesive tape to seal it.

[0053] The closed closing wing 2 is in direct contact with the operation panel 3. Since the packing boxes are generally stacked during transportation, on the one hand, under the action of gravity, the operation panel 3 cannot move, which can ensure that the limit rod 13 is stably located inside the limit hole 8 to ensure the limiting effect. On the other hand, the fixing plate 7 can be used as the X-axis support, and the operation panel 3 and the devices at its bottom can be used as the Y-axis and Z-axis supports to ensure that the packing box will not be deformed excessively due to external force extrusion, affecting the normal use of the internal items.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
