Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a corrugated paper box which is convenient for disassembly and assembly. Background Art

[0002] Durian pulp contains a variety of vitamins and is difficult to store. The rot loss rate is high during storage, transportation and sales. Since durian is prohibited from being transported by air, it can only be transported by land and water. However, due to the inevitable shaking during transportation, stricter packaging standards are required to avoid damage and cracking of the shell, deformation or leakage of the pulp. Corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers with their superior performance and good processing performance. Through reasonable design, corrugated boxes can withstand heavier products, and compared with wooden box transportation, they have the advantages of lighter weight, cleanliness and environmental protection. However, most of the existing corrugated boxes are made by nailing or gluing boxes. When not in use, they need to be reasonably stacked, otherwise they will be crushed and damaged. At the same time, when transportation is needed, the assembled corrugated boxes occupy more space, and the transportation cost of a large number of empty corrugated boxes is much higher than the cost of re-manufacturing corrugated boxes. Therefore, a large number of corrugated boxes will be abandoned after use. Utility Model Content

[0023] The present application will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0024] Please refer to Figures 1-5 In, a corrugated cardboard box that is convenient for disassembly and assembly provided in this embodiment includes: a corrugated cardboard shell 1. A through side outlet hole 2 is provided on the outer surface of one side of the corrugated cardboard shell 1, and an inner insertion hole 3 is provided on the inner surface of one side of the corrugated cardboard shell 1. A sealing plug 4 is arranged inside the side outlet hole 2. The outer surface of the corrugated cardboard shell 1 is penetrated by a lateral fixing rod 5. A box cover 6 is snap-connected to the upper surface of the corrugated cardboard shell 1. Limit seats 7 are arranged on the lower surface of the box cover 6 and the inner bottom surface of the corrugated cardboard shell 1. A longitudinal limiting rod 8 is arranged inside the corrugated cardboard shell 1. A placing seat 9 is fixedly arranged on the inner bottom surface of the corrugated cardboard shell 1, and a placing groove 10 is provided on the upper surface of the placing seat 9. And a relief groove 11 is provided in the exact middle of the placing groove 10;

[0025] In this embodiment, the corrugated cardboard box mainly includes a corrugated paper shell 1, a side outlet hole 2, an inner insertion hole 3, a sealing plug 4, a lateral fixing rod 5, a box cover 6, a limiting seat 7, a longitudinal limiting rod 8, a placement seat 9, a placement groove 10, a relief groove 11, and a non-destructive disassembly and assembly mechanism. The corrugated cardboard box provided in this solution realizes the disassembly and assembly of the cardboard box through the cooperation of the non-destructive disassembly and assembly mechanism and the folding of the corrugated paper shell 1, and cooperates with the lateral fixing rod 5 and the longitudinal limiting rod 8 to limit the articles, so that the articles will not impact the cardboard box and ensure the stability of the cardboard box.

[0026] In some embodiments, the non-destructive disassembly and assembly mechanism includes: a reinforcement groove 121 opened on the upper side surface of the corrugated paper shell 1, an insertion rod 122 snap-fitted inside the reinforcement groove 121, and an extension plate 123 fixedly connected to the outer surface of the insertion rod 122. During installation, the upper end of the corrugated paper shell 1 is folded into a box shape, and then the insertion rod 122 is longitudinally inserted into two mutually fitting reinforcement grooves 121, so that the side surface of the corrugated paper shell 1 can be fixedly limited. During disassembly, grasp the extension plate 123 and remove the insertion rod 122, then the corrugated paper shell 1 can be flattened for convenient transportation.

[0027] In some embodiments, the side outlet hole 2 and the inner insertion hole 3 are respectively located on two inner side surfaces of the corrugated paper shell 1 in opposite directions, and the side outlet hole 2 is penetrated by the lateral fixing rod 5, and the lateral fixing rod 5 is snap-fitted with the inner insertion hole 3, so that the lateral fixing rod 5 can be inserted into the corrugated paper shell 1 to prevent the article from swinging. By changing the positions of the side outlet hole 2 and the inner insertion hole 3 into which the lateral fixing rod 5 is inserted, the fixation of articles of different sizes can be realized, and the unused side outlet hole 2 is plugged tightly with a paper sealing plug 4.

[0028] In some embodiments, the sealing plug 4 is snap-fitted with the side outlet hole 2, and a circular plate-shaped protrusion is provided at one end of the sealing plug 4 facing the inside of the corrugated paper shell 1. The diameter of the circular plate-shaped protrusion of the sealing plug 4 is larger than the diameter of the side outlet hole 2, and the outer surface of the circular plate-shaped protrusion of the sealing plug 4 is fitted with the inner side surface of the corrugated paper shell 1, so that the side outlet hole 2 can be sealed by the sealing plug 4 when not in use to prevent foreign matters from entering the inside of the corrugated paper shell 1.

[0029] In some embodiments, the upper and lower ends of the longitudinal limiting rod 8 are respectively snap-fitted with the limiting seat 7 on the lower surface of the box cover 6 and the inner bottom surface of the corrugated paper shell 1, and the limiting seats 7 are evenly distributed around the placement seat 9 on the inner bottom surface of the corrugated paper shell 1. The limitation of articles of different sizes is realized by the way that the longitudinal limiting rod 8 is snap-fitted with the limiting seats 7 at different positions.

[0030] In some embodiments, the placement seat 9 is located exactly in the middle of the inner bottom surface of the corrugated paper shell 1, and the placement groove 10 on the upper surface of the placement seat 9 is designed as a downwardly concave arc, so that circular items can be placed in the placement groove 10 on the placement seat 9 to ensure the stability of the items. The raised portions on the surface of the items are given way through the relief groove 11 to prevent the items from being placed unevenly and wobbling randomly.

[0031] In some embodiments, both ends of the insertion rod 122 are designed as isosceles trapezoids, and both ends of the insertion rod 122 are designed in an L shape. One end of the extension plate 123 is located inside the cavity of the corrugated paper shell 1, so that the insertion rod 122 can be used to limit the folded and turned-up corrugated paper shell 1 through engagement with the reinforcement groove 121. When disassembling, the insertion rod 122 is lifted by the extension plate 123 protruding into the box body.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
