Description

Technical Field

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

[0002] A packaging box is a container used to store, protect and transport goods, usually made of cardboard, pulp or other materials. It plays a vital role in the transportation and storage of products. In particular, paper packaging boxes are widely used in the packaging of various commodities because of their light weight, easy processing and environmental protection.

[0003] Paper packaging boxes with interlayers provide additional protection, especially for transporting fragile items or multiple items that need to be stored separately. Although paper packaging boxes with interlayers have advantages in providing additional protection, many packaging boxes on the market currently have defects in the strength and durability of the interlayers. Usually, the interlayers are made of thinner cardboard or pulp materials, which are easily deformed or damaged after bearing heavy objects or experiencing long-term transportation. This lack of strength leads to a lack of adequate protection for the items in the box. In severe cases, the box may be deformed due to insufficient load-bearing or external squeezing and collision, causing damage to the items on the lower layer.

[0004] Therefore, there is an urgent need for a packaging box with a protective barrier to solve the technical defects proposed in the above technology. Utility Model Content

[0011] Preferably, the inner side walls of the limiting rings are welded with limiting blocks, and second corrugated paper strips are arranged between each of the limiting blocks, and the curvature of the second corrugated paper strips matches that of the limiting rings.

[0012] Preferably, a box cover is installed on the top of the outer box body, and a group of side buckles are provided on both sides of the top of the box cover, and hook strips are hung inside the side buckles. The hook strips are bent integrally to form a handle, and a convex handle is formed in the middle of the handle, and ground feet are welded at the four corners of the bottom end of the outer box body.

[0015] The packaging box is provided with positioning blocks, partitions, protective rods, corrugated paper strips, and slots. A group of positioning blocks is welded on the middle sections of both sides of the interior of the packaging box. The positioning blocks are triangular structures to improve the supporting force. A partition is pressed on the top to divide the outer box body into two upper and lower spaces. On the bottom surface of the partition, multiple groups of corrugated paper strips are used to improve the overall strength. Four groups of plug-in detachable protective rods are used to form bottom protection to prevent the partition from being squeezed, deformed, and collapsed due to impact on the items, thereby improving the protective effect of the partition.
