Description

Technical Field

[0001] This utility model relates to the field of packaging box placement technology, specifically a packaging box that can be stably stacked. Background Technology

[0002] In modern logistics, e-commerce, manufacturing, and many other industries, packaging boxes are indispensable tools for the transportation and storage of goods. From everyday consumer goods to industrial components, all kinds of products rely on packaging boxes for protection and transshipment. Stacking packaging boxes during warehousing and transportation can effectively save space and improve storage and transportation efficiency.

[0003] The prior art discloses a stackable water pump packaging box with announcement number CN205738568U, including a box body, a chassis, and a box cover. The surfaces of the chassis and the box cover are both square. Six uprights are evenly spaced on the surface of the chassis. The uprights are divided into three groups of two: a first group of uprights, a second group of uprights, and a third group of uprights. The first and second groups of uprights are symmetrically distributed on both sides of the chassis surface, and the third group of uprights is located between the first and second groups of uprights and arranged diagonally. The first, second, and third groups of uprights all have through holes in the same direction. The surface of the box cover has the same uprights as the chassis.

[0004] The aforementioned stable stackable packaging boxes have a stable center of gravity, can be stacked in multiple layers, occupy warehouse space reasonably, and have guaranteed safety, making them suitable for widespread promotion. However, the stable stackable packaging boxes use the method of inserting columns into the docking slots without setting locking components, which cannot ensure stability after placement and results in poor performance during use, requiring improvement.
