Description

Technical Field

[0001] The utility model relates to the technical field of large-size packaging cartons, and in particular to a special-shaped large-size carton with high bending strength. Background Technique

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. In order to package various different items, various suitable packaging boxes are required at this time. Among them, there are some large items, and large-size cartons are needed for packaging these large items. In some cases, special-shaped cartons are used for large items.

[0003] In the prior art, for smaller cartons, due to the small stress area, fewer support points are required, so the relative stability is high. As the size of the carton increases, with the increase of its stress area, the number of support points required will increase. Therefore, for large-size cartons, due to the increase in the stress area, it is easy to cause the side panels of the carton to be bent when packing heavy objects or stacking and transporting, and then it is easy to cause the overall inclination of the carton and the items packed inside to be crushed, thus affecting the transportation of the items. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a special-shaped large-size carton with high bending strength, so as to solve the technical problems mentioned in the above background technique.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A special-shaped large-size carton with high bending strength, including a paper box body. The side wall of the paper box body is hollow, a reinforcing member is arranged inside the wide side of the paper box body, and a supporting member is arranged inside the long side of the paper box body;

[0007] The supporting member includes cross beam paper rods, triangular paper blocks, longitudinal beam paper rods and inserted paper rods. The number of cross beam paper rods is several, and several cross beam paper rods are fixedly installed in the long side of the paper box body in a linear array. The number of triangular paper blocks is several, and several triangular paper blocks are respectively fixedly installed between two adjacent cross beam paper rods in a linear array. The number of longitudinal beam paper rods is several, and each longitudinal beam paper rod is vertically connected between two adjacent triangular paper blocks. The number of inserted paper rods corresponds to the number of triangular paper blocks, and each inserted paper rod is vertically installed in the corresponding triangular paper block.

[0008] In a preferred example, the present utility model can be further configured as follows: the side surfaces of the triangular paper blocks are respectively fixedly connected to two opposite side edges inside the side wall of the paper box body, and the top and bottom ends of the longitudinal beam paper rods are respectively fixedly connected to the corresponding two cross beam paper rods.

[0009] In a preferred example, the present utility model can be further configured as follows: a gap is left between two adjacent triangular paper blocks, and the corresponding longitudinal beam paper rod is fixedly installed in the gap between the two adjacent triangular paper blocks, and the axial side of the longitudinal beam paper rod is fixedly connected to the side edge inside the side wall of the paper box body.

[0010] In a preferred example, the present utility model can be further configured as follows: the reinforcing member includes a corrugated folding plate, the corrugated folding plate is fixedly installed inside the side wall with a wide edge of the paper box body, and the corners of the corrugated folding plate are respectively fixedly connected to the corresponding side walls inside the side with a wide edge of the paper box body.

[0011] In a preferred example, the present utility model can be further configured as follows: fixed paper rods are fixedly connected to the corresponding corners of the corrugated folding plate, and the two end portions of the fixed paper rods are respectively fixedly connected to the corresponding side walls inside the side with a wide edge of the paper box body.

[0014] 1. For this special-shaped large-sized paper box with high bending strength, during use, the triangular paper blocks and cross beam paper rods provided can support multiple points on the long side of the paper box body, thereby improving the stability of the paper box body. At the same time, the corrugated folding plate provided fixes the side with a wide edge of the paper box body, and through the reinforcement of the fixed paper rods and side fixing paper rods, the stability of the side with a wide edge of the paper box body is further improved, thereby improving the overall stability of the paper box body, enhancing the load-bearing capacity of the paper box body, and avoiding the paper box being crushed and bent due to transportation bumps, thus affecting the items inside the paper box body;

[0015] 2.
