Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a composite foam packaging box. Background Art

[0002] Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. They have the characteristics of light weight, heat insulation, sound absorption, shock absorption, and other properties. Their dielectric properties are better than those of the base resin, and they have a wide range of uses. Almost all kinds of plastics can be made into foam plastics, and foam molding has become an important field in plastic processing. Foam plastics are polymer materials with plastic as the basic component and containing a large number of bubbles. Therefore, they can also be said to be composite plastics with gas as filler. Compared with pure plastics, it has many excellent properties, such as light weight, high specific strength, ability to absorb impact loads, good heat insulation and sound insulation, etc. Therefore, it has been widely used in industries such as industry, agriculture, construction, and transportation.

[0003] Existing foam packaging boxes are usually made of a composite of multiple plastics. When placing items, ventilation is sometimes required. The first method is to directly open ventilation holes on the side of the packaging box body, but this easily causes external impurities to directly enter the interior, which is less safe. At the same time, when loading items, it is inconvenient to adjust the space size in the packaging box according to the size of the items, and the utilization rate is low. In order to solve the above problems, a composite foam packaging box is proposed. Utility Model Content

[0004] In response to the above technical problems, the utility model provides a composite foam packaging box, which is characterized by comprising a box body, a filter, an adjustment hole, a partition plate, a top plate, a limiting hole, a hard shell, a handle, a vent, a collection groove, a bottom plate, and a debris outlet. The filter is provided in the box body, the adjustment hole is provided at the bottom of the box body, a partition plate is provided on the adjustment hole, a top plate is provided on the box body, a limiting hole is provided on the top plate, a hard shell is provided outside the box body, a handle is provided on the hard shell, a vent is provided on the hard shell, a collection groove is provided in the hard shell, a bottom plate is provided below the hard shell, and a debris outlet is provided on the bottom plate.

[0005] Furthermore, the box body is fixedly arranged in the hard shell, the top plate is connected to the hard shell by a lock, there is an empty groove between the outer wall of the box body and the inner wall of the hard shell, there is a vent on each side of the hard shell, the vent leads to the empty groove, the collection groove is located below the empty groove, the lower end of the collection groove has an opening, and the opening of the collection groove is connected to the outlet of the bottom plate;

[0006] Furthermore, there is a filter screen on each side of the box body, and the outer side of the filter screen is in contact with the empty slot. There are two groups of adjustment holes at the bottom of the inner wall of the box body, and each group of adjustment holes has several holes, which are evenly distributed at the bottom of the box body. There are two groups of limiting holes on the top plate, which correspond to the positions of the two groups of adjustment holes. There are two protrusions at the upper and lower ends of the partition plate, which are respectively connected to the adjustment holes and the limiting holes. There are several partition plates.

[0007] Beneficial effects of the utility model:

[0008] The utility model adjusts the position of the partition plate, inserts the partition plate into the limiting hole at the appropriate position, and after the items are loaded, closes the top plate through the lock cover. At this time, the protrusions on the upper ends of the partition plate are inserted into the limiting holes of the top plate, so that the space inside the box can be adjusted. When ventilating, external impurities will enter the hard shell from the vent, and the filter screen on the box body will block the impurities. The impurities fall into the collection tank along the empty groove between the outer wall of the box body and the inner wall of the hard shell, and leave the device from the outlet of the bottom plate, avoiding the accumulation of impurities and preventing external impurities from directly entering the interior, thereby having higher safety. At the same time, when loading items, it is convenient to adjust the size of the space inside the packaging box according to the size of the items, and the space utilization rate is high.
