Description

Packaging structure

The invention relates to a packaging structure.

The current packaging method for electronic parts and other fragile items is to be loaded in a carton with multiple partitions inside. The industry refers to this packaging structure as a honeycomb partition. Specifically, the honeycomb partition system uses multiple partition plates to separate different packaging spaces to place multiple objects in the packaging space separately to avoid damage to the objects due to collisions during transportation. The situation happened.

FIG. 1 is a schematic diagram of a conventional packaging structure, that is, a schematic diagram of a traditional honeycomb partition. Please refer to FIG. 1. The conventional packaging structure 9 includes a box 91, a plurality of horizontal partitions 92, and at least two longitudinal partitions 93. Before the items are shipped, the packaging structure 9 must be assembled first. Generally speaking, the horizontal partition 92 and the vertical partition 93 have a plurality of clamping grooves, so the horizontal partition 92 and the vertical partition 93 can be assembled by mutual engagement. Then, the assembled horizontal partition 92 and the longitudinal partition 93 are placed in the box 91, as shown in FIG. 1. Finally, placing a plurality of objects (such as electronic components) to be transported separately in the packaging space divided by the horizontal partition 92 can achieve the effect of avoiding collision of the objects.

Among them, the longitudinal partition 93 is used to fix the interval width of the transverse partition 92. However, the horizontal partition 92 and the longitudinal partition 93 are assembled only by means of mutual engagement, and their structures are scattered and weak. Therefore, the combined horizontal partition 92 and the longitudinal partition 93 may fall off before the box 91 is placed. In addition, when the combined horizontal partition 92 and the longitudinal partition 93 are stacked and placed, the card grooves are more likely to be torn due to pulling, and there is a need for improvement.
