Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] The present utility model provides as Figures 1-4A detachable paper packaging box as shown includes a box body. Eight right-angle parts 2 are evenly distributed on the left and right sides of the box body. On one side of the outer walls of the eight right-angle parts 2, first chutes 3 are opened, and on the other side of the outer walls of the eight right-angle parts 2, second chutes 13 are opened. Two screws 4 are arranged outside each of the eight first chutes 3 and the eight second chutes 13. The threaded ends of the multiple screws 4 are threadedly connected to a light steel bar 5. A right-angle strip 6 is arranged on the inner wall of the right-angle part 2. The box body formed by the cardboard 1 forms a cube. A total of eight edges on the left and right sides of the cube are provided with right-angle parts 2 made of light steel. The lengths of the right-angle parts 2 have various specifications to adapt to box bodies of different capacities. When the eight right-angle parts 2 are placed in the same direction, such as Figure 2 , at this time, a first chute is opened at the bottom left of the right-angle part 2, a second chute 13 is opened at the upper left of the left side of the right-angle part 2, a first limiting groove 7 is opened on the right side of the right-angle part 2, and a second limiting groove 10 is opened at the top. After the detachable packaging box is assembled, two screws 4 pass through both the first chute 3 and the second chute 13 and are screwed into the light steel bar 5 to realize the connection between the light steel bar 5 and the right-angle part 2. The light steel bar 5 surrounds the six sides of the box body to form a keel-type framework, preventing the detachable carton from loosening and strengthening the connection between the right-angle parts 2.
[0023] The box body includes six cardboard sheets 1. Folding edges 12 are folded at both ends of the six cardboard sheets 1. The box body is composed of six cardboard sheets 1 to form the six sides of a cube. The cardboard sheet 1 at the top is cut in half as an opening. To strengthen the connection between the cardboard sheets 1 after combination and save paper, folding edges 12 with the same width as the inner wall of the right-angle part 2 are folded at both ends of the six cardboard sheets 1. When two cardboard sheets 1 are clamped by the right-angle part 2 and the right-angle strip 6, the two cardboard sheets 1 and the folding edges 12 are all in a right-angle state, and the two right angles coincide and are clamped by the inner corner of the right-angle part 2 and the outer corner of the right-angle strip 6, which not only reduces the possibility of falling apart but also facilitates the targeted replacement of the cardboard sheets 1 on different sides of the box body when damaged, reducing resource waste.
[0024] Threaded holes for threaded connection with multiple screws 4 are opened at both the left and right ends of the multiple light steel bars 5. The multiple light steel bars 5 can all slide between two adjacent right-angle parts 2. The multiple light steel bars 5 are all arranged outside the box body. One threaded hole is arranged at both the left and right ends of each light steel bar 5. Each threaded hole is used for the screw 4 to pass through the first chute 3 or the second chute 13 and be threadedly connected to the light steel bar 5. The position of the light steel bar 4 is adjusted according to the main pressure area of the items loaded in the packaging box. After determining the position, tightening the screw 4 can realize the positioning of the light steel bar 4, support the main pressure area, and enhance the packaging durability of the packaging box.
[0025] One end of each of the eight right-angle members 2 is provided with a first limiting groove 7, and the other end of each of the eight right-angle members 2 is provided with a second limiting groove 10. The ends of multiple light steel bars 5 can slide in the eight first limiting grooves 7 and the eight second limiting grooves 10. The first limiting groove 7 and the second limiting groove 10 are used to accommodate both ends of each light steel bar 5, isolate both ends of the light steel bar 5 from the cardboard 1, avoid damage to the cardboard 1 caused by non-paper parts, and improve durability.
[0026] Multiple folding edges 12 are respectively arranged between the eight right-angle members 2 and the eight right-angle bars 6. Four first round holes 9 are evenly opened on the eight right-angle members 2, four third round holes 14 are evenly opened on the eight right-angle bars 6, and four second round holes 11 are evenly opened on multiple folding edges 12 and six cardboard sheets 1. Bolts 8 respectively penetrate through the multiple first round holes 9, the multiple second round holes 11 and the multiple third round holes 14. The first round hole 9, the second round hole 11 and the third round hole 14 are distributed left and right on the same right-angle member 2, right-angle bar 6, folding edge 12 and cardboard 1. The first round holes 9, the second round holes 11 and the third round holes 14 on the left and right sides are respectively communicated, and one bolt 8 can pass through each of the left and right sides, so that both ends of the bolt 8 are respectively located outside the right-angle member 2 and inside the right-angle bar 6. The middle of the bolt 8 penetrates through the folding edge 12 and the cardboard 1 near both ends. As the screw and nut of the bolt 8 are tightened, the gap between the right-angle bar 6 and the right-angle member 2 is compressed, and the cardboard 1 near both ends and the folding edge 12 are tightly clamped between the right-angle bar 6 and the right-angle member 2, realizing the assembly of the cardboard 1 into the packaging box.
