Description

Technical Field

[0001] This utility model belongs to the field of cardboard box technology, specifically relating to an environmentally friendly corrugated cardboard box corner reinforcement lining. Background Technology

[0002] Environmentally friendly corrugated cardboard boxes are packaging containers made primarily of corrugated cardboard. Their structure consists of a corrugated core layer and at least one flat linerboard bonded together. Compared to traditional packaging materials, corrugated cardboard's main raw material is plant fiber, a renewable source, and its production process requires no large amounts of chemical adhesives, reducing harmful emissions.

[0003] Environmentally friendly corrugated cardboard boxes typically have reinforcing linings placed at their internal right angles to increase their load-bearing capacity. However, current reinforcing linings are simply placed directly at these right angles without any positioning assistance. This means that when goods are placed into the box, the resulting shaking can cause the lining to wobble and tip over, requiring it to be repositioned before further handling. This restricts the initial loading process for boxes with reinforcing linings. Utility Model Content

[0004] The purpose of this utility model is to provide a corner reinforcement liner for environmentally friendly corrugated cardboard boxes. This addresses the issue of placing a reinforcement liner at the right angles inside the box during use, which would increase the box's load-bearing capacity. Currently, reinforcement liners are simply placed directly at the right angles of the box, lacking a positioning function. This means that when goods are placed inside the box, the resulting shaking can cause the liner to wobble and tip over, requiring it to be repositioned before proceeding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly corrugated cardboard box corner reinforcement liner, comprising a corrugated cardboard box, wherein each of the four right-angled ends of the corrugated cardboard box is provided with an liner, the liner having an L-shaped structure and its outer wall being adapted to the inner wall of the right-angled ends of the corrugated cardboard box;

[0006] Two left horizontal strips are glued to one side of the outer wall of the inner lining, and two right horizontal strips are glued to the other side of the outer wall of the inner lining. Each pair of inner linings is supported inside the corrugated cardboard box by the mating of the corresponding left and right horizontal strips.

[0007] In order to ensure that the inner lining, left horizontal strip, and right horizontal strip effectively reinforce the inside of the corrugated cardboard box, as an environmentally friendly corner reinforcement lining of the corrugated cardboard box according to this utility model, preferably, the inner lining, left horizontal strip, and right horizontal strip are all made of hard rubber.

[0008] In order to ensure that the left and right horizontal bars can be completely joined together, as an environmentally friendly corrugated cardboard box corner reinforcement lining of this utility model, preferably, the joint ends of the left and right horizontal bars are provided with matching inverted L-shaped notches.

[0009] A movable block is fixedly bonded to the inner wall of the L-shaped notch of the left horizontal bar. A guide rod moves through the interior of the movable block. The two ends of the guide rod are fixedly connected to the inner walls of the two ends of the rectangular groove, which is opened on the L-shaped notch of the right horizontal bar.

[0010] In order to allow for adjustment of the lateral length between the left and right horizontal bars, as an environmentally friendly corrugated cardboard box corner reinforcement lining of this utility model, preferably, the movable block is movably connected inside the rectangular groove, and a spring is sleeved on the outer wall of one side of the guide rod. One end of the spring abuts against the outer wall of one side of the movable block, and the other end of the spring abuts against the inner wall of one end of the rectangular groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Place the four liners inside the corrugated cardboard box, then release the restraints. The springs will then return to their original position, pushing a movable block to move. This movement of the movable block, in turn, moves the left crossbar. The left crossbar then pushes the corresponding liners to move, ultimately securing the liners stably against the corners of the corrugated cardboard box. This structure allows for the adaptation to various sizes of corrugated cardboard boxes, and the liners are less likely to tip over once placed inside, facilitating the subsequent stacking of goods within the box and improving the overall practicality and coordination between the corrugated cardboard box and the liners.

[0020] Two left horizontal strips 3 are glued to one side of the outer wall of the inner lining 2, and two right horizontal strips 4 are glued to the other side of the outer wall of the inner lining 2. Each pair of inner linings 2 is supported inside the corrugated cardboard box 1 by the mating support between the corresponding left horizontal strips 3 and right horizontal strips 4.

[0021] When in use, the four inner linings 2 are placed at the four right-angled ends inside the corrugated cardboard box 1. In this way, the inner linings 2 can enhance the load-bearing capacity of the four right-angled ends inside the corrugated cardboard box 1 during use, thereby improving the load-bearing strength of the corrugated cardboard box 1.

[0022] Preferably, the inner lining 2, the left horizontal strip 3, and the right horizontal strip 4 are all made of hard rubber.

[0023] In practical use, the hard rubber lining 2, left horizontal bar 3 and right horizontal bar 4 can not only enhance the load-bearing strength of the corrugated cardboard box 1, but also prevent the lining 2, left horizontal bar 3 and right horizontal bar 4 from water stains during use, thereby ensuring the performance of the lining 2, left horizontal bar 3 and right horizontal bar 4.

[0024] Preferably, the left horizontal bar 3 and the right horizontal bar 4 have matching inverted L-shaped notches at their mating ends;
