Description

Stackable packing box

Technical Field

The invention relates to a packaging box, in particular to a stackable packaging box.

Background

The liquid crystal panel is an important component of an electronic product having a display function such as a television, a computer, and a mobile phone, and it needs to be transported to an assembly or processing shop of the above electronic product by a transport device. However, both the semi-finished liquid crystal panels (Open Cell) and the finished liquid crystal panels need to be packaged and transported by using a packaging box to ensure the transportation safety of the finished liquid crystal panels and the semi-finished liquid crystal panels.

Plastic injection molding boxes, such as High Density Polyethylene (HDPE), have the characteristics of High strength, difficult damage, repeated recycling and the like, and are widely applied to packaging of liquid crystal panels at present. Meanwhile, the packing box is made of hard materials and has poor buffering performance, so the packing box is usually used together with a soft retaining wall when being used for packing the liquid crystal panel.

In the transportation process of the liquid crystal panel, the packing box placed on the pallet needs to be stacked in multiple boxes to save space, as shown in fig. 1, the existing packing box 90 includes a box body 91 for accommodating the product, and a circle of protrusions 93 and a circle of grooves 92 are respectively provided at the outer edge of the top end and the outer edge of the bottom end of the box body 91. After any two packing cases 90 are stacked on each other, the protrusion 93 of the packing case 90 at the lower position can be inserted into the groove 92 of the packing case 90 at the upper position, so as to enhance the stability of the stacked packing case group.

However, in order to facilitate the packaging operation and reduce the difficulty of the process, a certain assembly gap needs to be reserved for the matching between the packaging boxes 90, the width of the protrusion 93 is usually configured to be smaller than the width of the groove 92, meanwhile, the packaging boxes 90 are made of plastic materials, the materials of the packaging boxes are hard, and the surface friction force is small, so that the stacked packaging boxes 90 easily shake in the horizontal direction in a transportation link, and the horizontal direction impact is caused between the liquid crystal panel 80 packaged inside the packaging box 90 and the retaining wall 95 arranged on the side wall of the packaging box 90, and the liquid crystal panel 80 is damaged, and other disadvantages are caused.

In addition, as shown in fig. 2, since the number of the liquid crystal panels 80 loaded on the packing boxes 90 is large, the packing boxes 90 are heavy after being stacked, and the side walls of the packing boxes 90 located at the bottom layer are deformed and turned outwards due to excessive pressure, so that the risk of falling of the packing boxes exists.
