Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard box technology, and more specifically, it relates to a shock-absorbing corrugated cardboard box structure. Background Technology

[0002] When transporting and storing goods, in order to ensure the integrity of the goods and improve the turnover and reuse rate, shock-absorbing corrugated cardboard boxes are usually used to package the goods. During the transportation and storage process, the corrugated cardboard core in the corrugated cardboard box absorbs the impact and vibration during transportation through its own deformation and compression, so as to prevent the goods from being damaged due to bumps and collisions.

[0003] For example, existing application number CN202320044291.9 discloses a shock-absorbing and vibration-damping corrugated cardboard box, relating to the field of corrugated cardboard box technology. Specifically, it is a shock-absorbing and vibration-damping corrugated cardboard box, including a first corrugated cardboard box and a semi-support box. A support shaft is rotatably connected to one side of a convex long plate. This shock-absorbing and vibration-damping corrugated cardboard box, through the setting of a second limiting long plate, has the effect of increasing the firmness between the two semi-support boxes. Through the cooperative arrangement of the semi-support boxes, support shaft, concave long plate, and convex long plate, a good shock-absorbing and vibration-damping effect is achieved. Through the setting of a conical column, the shock-absorbing and vibration-damping corrugated cardboard box has the effect of preventing the second support column from shaking when rotating. Through the cooperative arrangement of the first semi-circular long plate, the second support column, and the limiting column, the two circular square plates can protrude from the outer sides of the two semi-support boxes during use, achieving the purpose of convenient handling.

[0004] Based on the above, when using corrugated cardboard boxes to package fruits and vegetables, the boxes are easily soaked by moisture released continuously from the respiration of the fruits and vegetables, residual moisture on the surface of the fruits and vegetables after washing, and condensation formed when low-temperature fruits come into contact with room-temperature air due to temperature differences. This not only affects the strength and stiffness of the cardboard box, causing deformation and damage, thus affecting the protection of the fruits and vegetables, but also easily leads to mold and rot due to the accumulation of moisture inside the box. This causes the fruit and vegetable skin to become sticky, affecting the taste, shortening the shelf life of the fruits and vegetables, and affecting the quality of the fruits and vegetables during transportation and storage. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a shock-absorbing corrugated cardboard box structure. This solves the problem that when using corrugated cardboard boxes to package fruits and vegetables, moisture is easily released due to the respiration of the vegetables, residual moisture from washing the fruits and vegetables seeps into the box, and condensation forms on the inner wall of the box due to the temperature difference when low-temperature fruits come into contact with room-temperature air. This wetness not only affects the strength and stiffness of the box, causing deformation and damage, thus affecting the protection of the fruits and vegetables, but also easily leads to mold and rot due to moisture accumulation inside the box. This causes the fruit and vegetable skins to become sticky, affecting the taste, shortening the shelf life, and impacting the quality of transporting and storing the fruits and vegetables.

[0006] The purpose and effect of this utility model's shock-absorbing corrugated cardboard box structure are achieved through the following specific technical means: A shock-absorbing corrugated cardboard box structure includes a corrugated cardboard box body, a top plate, shock-absorbing corrugated sheets, isolation corrugated sheets, and a drainage guide structure. The top plate is hinged to the rear side of the top end face of the corrugated cardboard box body; a positioning bracket is fixedly connected to the front side of the bottom end face of the top plate; the shock-absorbing corrugated sheets are inserted into the inner side of the corrugated cardboard box body; multiple isolation corrugated sheets are arranged vertically and inserted into the top end face of the shock-absorbing corrugated sheets; multiple receiving through holes are evenly arranged on the inner side of the isolation corrugated sheets; the receiving through holes penetrate the isolation corrugated sheets, and the receiving through holes are conical groove structures with an upper diameter larger than the lower diameter; the drainage guide structure is located at the upper end of the shock-absorbing corrugated sheets.

[0007] Furthermore, insertion slots are provided on the left and right sides of the upper end of the isolation corrugated sheet; insertion posts are fixedly connected on the left and right sides of the bottom end face of the isolation corrugated sheet; the insertion slots on the same side are adapted to the insertion posts.

[0008] Furthermore, shock-absorbing corrugated frames are fixedly connected to the left and right sides of the bottom end face of the shock-absorbing corrugated plate; positioning supports are fixedly connected to the left and right sides of the top end face of the shock-absorbing corrugated plate; the positioning supports on the same side are compatible with the plug-in columns at the bottom end.

[0009] Furthermore, multiple guide channels are arranged circumferentially at the contact surface between the through hole and the fruit and vegetables; the edges of the guide channels are rounded.

[0010] Furthermore, multiple ventilation openings are evenly arranged on the inner side of the top plate; ventilation balance strips are connected to the edges of the ventilation openings by dotted lines.

[0011] Furthermore, the drainage guiding structure includes: drainage guide channels and drainage through holes. There are multiple drainage guide channels, which are evenly arranged on the top end face of the shock-absorbing corrugated board. The drainage guide channels are aligned with the receiving through holes. The left and right ends of the drainage guide channels are inclined groove-shaped structures that slope from the upper inner end to the lower outer end. There are multiple drainage through holes, which are evenly arranged on the lower side of the left and right end faces of the corrugated cardboard box body. The drainage through holes are located on the left and right sides of the drainage guide channels.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When in use, the accommodating through holes of the isolation corrugated board allow for independent separation of fruits and vegetables, preventing them from being squeezed and collided during transportation. Combined with the rounded transition design of the guide channel, it reduces scratches on the surface of fruits and vegetables. The shock-absorbing corrugated frame absorbs the impact and vibration of transportation through the deformation and compression of its own corrugated structure. The positioning support and plug-in structure make the isolation corrugated board and the shock-absorbing corrugated board form a stable whole, preventing stacked fruits and vegetables from shaking and shifting, thus providing double protection for the integrity of fruit and vegetable transportation. In use, this invention forms a complete drainage path with the through-hole and the drainage channel. The water vapor released by the fruits and vegetables, the surface moisture, and condensation can flow into the inclined drainage channel along the through-hole and finally be discharged out of the box through the drainage hole, greatly avoiding the accumulation of water vapor. At the same time, the corrugated board completely separates the fruits and vegetables from the box walls and bottom, forming an air buffer layer and reducing the area of ​​water vapor in direct contact with the cardboard. The ventilation balance strip on the top plate can flexibly adjust the size of the ventilation openings to adapt to different humidity environments, balance the moisture retention needs of fruits and vegetables with the moisture protection needs of the cardboard, prevent the cardboard from getting wet, deformed, or damaged, and maintain the strength and stiffness of the cardboard.

[0013] When in use, this utility model reduces squeezing damage between fruits and vegetables through independent partition design, and the arc transition structure of the guide channel avoids scratching the skin of fruits and vegetables, ensuring the appearance of fruits and vegetables is intact; timely discharge of moisture can effectively inhibit the growth of mold in the box, prevent fruits and vegetables from becoming moldy and rotten, prevent the skin from becoming sticky, maintain the original taste and quality of fruits and vegetables, greatly extend the shelf life of transportation and storage, and improve the quality of fruit and vegetable circulation.
