Technical Field

[0001] The utility model relates to the technical field of packaging boxes, and particularly relates to a packaging box with a deformation prevention function. Background Art

[0002] A packaging box is used to package products. There are a large number of packaging boxes required in the current market. Its functions are to ensure the safety of products during transportation and improve the grade of products. Most of the existing packaging boxes are made of paper, and most of them do not have the function of preventing deformation. During transportation, it is often easy to cause the deformation of the packaging box due to greater external pressure or external extrusion, which is likely to damage the internal items, and there is also a phenomenon that the opening of the packaging box is caused by extrusion deformation, which cannot meet the use requirements. Therefore, we propose a packaging box with a deformation prevention function to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a packaging box with a deformation prevention function to solve the problems in the background art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A packaging box with a deformation prevention function includes a box body. First protective strips made of epoxy resin are arranged at four corners along the height direction and four sides of the bottom in the box body. Second protective strips are arranged crosswise between the first protective strips on the same side. Third protective strips are arranged crosswise at the bottom of the box body. Two perpendicular sides at the upper end of the box body are respectively provided with a first cover sheet and a second cover sheet, and the first cover sheet and the second cover sheet are movably connected. Handles are arranged on both sides of the box body.

[0006] Further, notches are arranged at both ends of the first cover sheet, fixing pieces are arranged at both ends of the second cover sheet, folding pieces are arranged on both sides of the front end of the fixing piece, and the width of the fixing piece is the same as the width of the notch.

[0007] Further, each surface of the box body includes a base layer. The upper and lower ends of the base layer are respectively a double copper paper layer and a kraft paper layer. The base layer is composed of a plurality of continuously arranged semi-circular cardboard sheets, and the upper and lower ends of the cardboard sheets are fixedly connected to the double copper paper layer and the kraft paper layer.

[0008] Further, the thickness of the double copper paper layer is the same as the thickness of the kraft paper layer, and the thickness of the double copper paper layer is 0.33 - 0.35 times the thickness of the base layer.

[0009] Further, both ends of the handle penetrate through the side wall of the box body and are fixedly connected with fixing blocks, and the fixing blocks are adhered to the inner side wall of the box body.

[0010] After adopting the above technical solution, the utility model has the following beneficial effects:

[0011] In the packaging box of the utility model, first protective strips made of epoxy resin are arranged at the four corners inside the box body and the four sides of the bottom, and crossed second protective strips are arranged on each side, and crossed third protective strips are also arranged at the bottom, so as to support the packaging box, improve its stability and prevent deformation. Moreover, each surface of the box body is a three-layer structure, including a base layer, a double copper paper layer and a kraft paper layer, which can improve the impact resistance of each surface of the box body and is not easy to deform.

Second protective strips 3 which are cross-set are provided between the first protective strips 2 on the same side. Third protective strips 4 which are cross-set are provided at the bottom of the box body 1. At the upper end of the box body 1, two perpendicular sides are respectively provided with a first cover piece 5 and a second cover piece 6, and the first cover piece 5 and the second cover piece 6 are movably connected. Handles 7 are provided on both sides of the box body 1. The two ends of the handle 7 penetrate through the side wall of the box body 1 and are fixedly connected with fixing blocks 8, and the fixing blocks 8 adhere to the inner side wall of the box body 1. In this paper box, first protective strips 2 made of epoxy resin are provided at the four corners inside the box body 1 and at the four sides of the bottom, and cross second protective strips 3 are provided on each side, and cross third protective strips 4 are also provided at the bottom, so as to be able to support the packaging box, improve its stability and prevent deformation.

[0020] Further, notches 9 are provided at both ends of the first cover piece 5, fixing pieces 10 are provided at both ends of the second cover piece 6, folding pieces 11 are provided on both sides of the front end of the fixing piece 10, and the width of the fixing piece 10 is the same as the width of the notch 9. The upper end of the box body 1 is movably connected and is movably shielded by the first cover piece 5 and the second cover piece 6 for convenient opening. First, cover the second cover piece 6, then fold the folding pieces 11 on the second cover piece 6 towards the fixing piece 10, then make the fixing piece 10 pass through the notch 9 from the lower end of the first cover piece 5, and finally flatten the folding pieces 11. At this time, the folding pieces 11 and the front end of the fixing piece 10 are on the upper surface of the first cover piece 5, and the folding pieces 11 can block the notch 9, so that the first cover piece 5 is not easily lifted.
