Description

Technical Field

[0001] The utility model belongs to the technical field of carton packaging boxes, and particularly relates to a carton packaging box with a corner reinforcement structure. Background Art

[0002] Carton packaging is a commonly used packaging material, mainly made of paper materials such as cardboard or corrugated paper. It is light, easy to fold, and recyclable. It is widely used in the packaging and transportation of various commodities. Cartons can be customized in different sizes and shapes as needed to meet the packaging needs of different commodities.

[0003] Because cardboard packaging is primarily made of paper, this characteristic significantly reduces its overall weight, making it easier to handle and transport, while also reducing logistics costs. However, this paper nature also presents certain limitations. The edges and corners of cardboard packaging are relatively fragile and susceptible to deformation or even damage when subjected to external pressure or impact. This deformation and damage not only affects the overall appearance of the cardboard packaging, making it less aesthetically pleasing, but more importantly, it impairs the cardboard packaging's load-bearing capacity, reducing its ability to protect the goods inside. Utility Model Content

[0004] The purpose of the present utility model is to provide a carton packaging box with a corner reinforcement structure, aiming to solve the problem that the main material used in the carton packaging box is paper. This feature greatly reduces the overall weight of the carton packaging box, making it easier to handle and transport, while also reducing logistics costs. However, the characteristics of paper also bring certain limitations. The corners of the carton packaging box are relatively fragile. When subjected to external compression or impact, these corners are prone to deformation or even damage. This deformation and damage not only affects the overall appearance of the carton packaging box, making it appear less beautiful, but more importantly, it destroys the force-bearing capacity of the carton packaging box and reduces its ability to protect the goods inside.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a carton packaging box with a corner reinforcement structure, comprising a carton packaging box, wherein a first vertical rod is respectively provided on the outer wall at each of the four corners of the carton packaging box, the first vertical rod being vertically connected to a second vertical rod on one side of the outer wall, and the first vertical rod and the second vertical rod being wrapped around the corners of the carton packaging box;

[0006] At least two first cross bars are fixedly connected between the two first vertical bars, and at least two second cross bars are fixedly connected between the two second vertical bars. The first vertical bars, first cross bars, second vertical bars and second cross bars are respectively provided in two groups and are installed around the outside of the carton packaging box.

[0007] In order to further enhance the stability of the carton, at least three first cross bars are fixedly connected between two of the first vertical bars, and at least three second cross bars are fixedly connected between two of the second vertical bars.

[0008] To allow the second vertical bar to dock with the first vertical bar, a preferred embodiment of the present invention's cardboard packaging box with a corner reinforcement structure includes a set of equally spaced inserts fixedly mounted on one side of the first vertical bar, each of which has through-holes formed therethrough. A set of equally spaced notches are formed on the outer wall of the second vertical bar on the side where it docks with the first vertical bar, and a polished rod is inserted inwardly from the top of the second vertical bar, extending through each of the notches.

[0009] In order to enable the plug-in blocks to be smoothly plugged into the corresponding recesses, as a preferred carton packaging box with a corner reinforcement structure of the present invention, the internal dimensions of the recesses are adapted to the dimensions of the plug-in blocks, and the spacing between each two adjacent recesses is adapted to the spacing between each two adjacent plug-in blocks.

[0010] In order to ensure that the insert block maintains a relatively fixed connection with the recess after being inserted into the recess, as a preferred embodiment of the present invention's cardboard packaging box with a corner reinforcement structure, the first vertical rod and the second vertical rod are connected by plugging the insert block into the recess. The smooth rod passes through the recess and also through the through hole, thereby forming a fixed connection between the first and second vertical rods.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The first and second vertical rods are connected together by docking the insert on one side of the first vertical rod with the notch on one side of the second vertical rod, and then inserting the light rod from the top of the second vertical rod into the interior of the second vertical rod. When in use, the assembled first and second vertical rods are wrapped around the corners of the corresponding carton packaging box. As a result, the corners of the carton packaging box can be reinforced by the above structure when in use, so as to prevent the corners of the carton packaging box from being easily deformed when squeezed, and unable to maintain a good appearance of the carton packaging box, and also enable the carton packaging box to maintain a good stress-bearing structure.
