Description

Technical Field

[0001] This application relates to the field of cardboard box technology, and in particular to a load-bearing cardboard box. Background Technology

[0002] Corrugated cardboard boxes are widely used in many industries such as packaging and transportation, serving to protect goods and facilitate packaging, storage, and transportation.

[0003] Chinese Patent Publication No. CN210133415U discloses a load-bearing cardboard box, which includes an outer cardboard box and a liner. The outer cardboard box is made of five-layer AB corrugated cardboard, and the liner is made of three-layer B corrugated cardboard. The liner includes a horizontal base plate and two vertical plates located opposite each other on the left and right sides of the base plate. The vertical plates are integrally formed with the base plate. The two vertical plates are respectively close to the two opposite inner side walls of the outer cardboard box. The top height of the vertical plates is flush with the inner height of the outer cardboard box. The base plate is placed on the bottom wall of the outer cardboard box. The corrugated core layer in the vertical plates is arranged vertically. Several reinforcing columns are inserted in the corrugated core layer of the two vertical plates. The height of the reinforcing columns is equal to the height of the vertical plates. Fixing ribs are pasted on the outer side walls of the vertical plates. The inner side walls of the outer cardboard box are provided with grooves that match the position and structure of the fixing ribs. The fixing ribs are embedded in the grooves. Although these heavy-duty cardboard boxes have added padding inside and improved overall load-bearing capacity through the addition of bottom and upright plates, when used to place metal shafts, the weight of a single metal shaft is relatively large, and multiple shafts are usually placed in a single box. These metal shafts are placed directly inside the box. To prevent the metal shafts from moving inside the box, partitions are usually placed inside the box using hot melt adhesive. However, the adhesive partitions may come loose due to the force of the metal shafts or if they are not properly glued, causing the metal shafts to collide or squeeze together. This results in uneven load distribution at the bottom of the box, which can lead to damage during transportation and reduce the box's load-bearing capacity. Utility Model Content

[0004] The purpose of this application is to provide a load-bearing cardboard box that improves the load-bearing capacity of the cardboard box.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a load-bearing cardboard box. Includes the enclosure, load-bearing base plate, and two fixed plates; The two ends of the load-bearing base plate are bent upward to form fixed side plates, and the two ends of the fixed side plates away from the load-bearing base plate are provided with first insertion grooves. The two fixing plates are located on both sides of the fixing side plate, and the fixing plates are provided with a second insertion groove that mates with the first insertion groove; the fixing plates are provided with a placement groove for placing the long shaft. The load-bearing base plate, the fixed plate, and the fixed side plate form a load-bearing box with an opening at the top; At least one load-bearing box is placed inside the box.

[0006] By adopting the above technical solution, the fixing plate is inserted into the fixing side plate through the second insertion slot, thereby forming a load-bearing box without the need for adhesive. Simultaneously, the fixing plate also secures the fixing side plate, preventing it from folding outwards due to the restoring force at the connection point with the load-bearing base plate. The placement slot allows for the placement of the long shaft, with both ends supported by the fixing plate. This allows the weight of the long shaft to act on the fixing plate, which then applies this force to the fixing side plate. This ensures that both the fixing plate and the fixing side plate simultaneously distribute the weight of the long shaft onto the load-bearing base plate, which is in surface contact with the bottom of the box. This distributes the weight of the long shaft evenly across the bottom of the box, improving the overall load-bearing capacity of the carton. The weight of the long shaft on the fixing plate makes the insertion and connection between the fixing plate and the fixing side plate tighter and more stable, resulting in a more stable overall structure of the load-bearing box.

[0007] Furthermore, the fixed side plate is perpendicular to the load-bearing base plate; When the fixing plate is inserted into the fixing side plate, the lower side of the fixing plate located between the two fixing side plates abuts against the load-bearing base plate, the lower side of the fixing plate located outside the two fixing side plates is flush with the bottom surface of the load-bearing base plate, and the upper side of the fixing plate is flush with the upper side of the fixing side plate.

[0008] By adopting the above technical solution, the lower side of the fixing plate inside the fixing side plate abuts against the load-bearing base plate, while the lower side outside the fixing side plate is flush with the load-bearing base plate. When the long axis is placed on the fixing plate, the weight of the fixing plate can be applied to the load-bearing base plate and the bottom of the box through the entire lower side of the fixing plate, thereby achieving uniform force distribution and improving the overall load-bearing capacity of the carton.

[0009] Furthermore, the bottom of the placement groove is an arc shape adapted to the shape of the long axis.

[0010] By adopting the above technical solution, when the long shaft is placed on the placement groove, the arc-shaped placement groove can fully contact the bottom of the long shaft, so that the placement groove is not easily deformed or damaged when supporting the long shaft.

[0011] Furthermore, the thickness of the fixing plate is 0.5 to 3 cm.

[0012] By adopting the above technical solution, the thickness of the fixing plate is increased to 0.5 to 3 cm, which increases the contact surface between the fixing plate and the load-bearing base plate and the box body, and provides extra capacity to improve the even distribution of force. When the fixing plate is inserted into the fixing side plate, the thicker fixing plate can better clamp the fixing side plate, improve the strength of the contact surface between the fixing side plate and the fixing plate, and make the fixing layer less prone to deformation and collapse under the weight, thereby improving the overall load-bearing capacity. In addition, since the thickened fixing plate is inserted into the fixing side plate and not around the outside of the long axis, the overall strength of the carton is improved without increasing the overall volume.

[0013] Furthermore, the opening of the first insertion slot is provided with a chamfer to facilitate the insertion of the fixing plate.

[0014] By adopting the above technical solution, the chamfer setting helps operators quickly insert the fixing plate into the fixing side plate, thus improving installation efficiency.

[0015] Furthermore, the two sides of the fixing plate abut against the inner side of the box body; The two sides of the fixed side plate abut against the inner side of the box.

[0016] By adopting the above technical solution, both the fixed plate and the fixed side plate abut against the inside of the box, which can stabilize the load-bearing box on the one hand; on the other hand, when multiple load-bearing boxes are placed inside the box, the upper and lower load-bearing boxes can overlap vertically due to the side enclosure, that is, the upper and lower adjacent fixed side plates are on the same vertical line, and the upper and lower adjacent fixed plates are on the same vertical line, thereby giving the load-bearing box better load-bearing capacity and stability.

[0017] Furthermore, the housing includes side enclosures with openings at both ends, a bottom cover and a top cover that respectively cover the two enclosures. The top cover includes a cover plate and a rim fixed around the cover plate. The bottom cover has the same structure as the top cover. The inner side of the rim abuts against the outer side of the side enclosure opening.

[0018] By adopting the above technical solution, the box is divided into a bottom cover, a top cover, and side panels, which makes it easy to disassemble and transport during transportation, saving transportation space.

[0019] In summary, this application has the following beneficial effects: By placing the long shaft on the placement slot and supporting it, the weight of the long shaft is applied to the load-bearing base plate through the fixed side plate and the fixed plate, and then the load is evenly applied to the bottom of the box through the surface contact with the box body, thus avoiding uneven or concentrated gravity that would reduce the load-bearing capacity of the box body. The arc-shaped placement groove is less likely to be damaged when placing long shafts; The bottom of the load-bearing box, which consists of a load-bearing base plate, a fixed plate, and fixed side plates, is flush, which helps to distribute the force evenly, prevents the force from being concentrated and causing damage, and improves the load-bearing capacity of the box. The modular design and plug-in structure save transportation space and reduce transportation costs. Attached Figure Description

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] In this embodiment, the long shaft that can be placed in the load-bearing cardboard box includes the rotating shaft 6 used in the automotive industry or other long shafts in other fields. This embodiment uses the rotating shaft 6 as an example to describe the embodiment.

[0024] This embodiment discloses a load-bearing cardboard box, such as Figure 1 , 3As shown in Figure 4, the box includes a corrugated cardboard box body 1, a load-bearing base plate 2, and two fixing plates 3. The load-bearing base plate 2 is bent upwards at 90° on opposite sides to form fixed side plates 21 of the same size. Two first insertion slots 211 are provided on the side of the fixed side plate 21 away from the load-bearing base plate 2, located near both ends of the fixed side plate 21. Two second insertion slots 31 are provided on one side of the fixing plate 3 to engage with the first insertion slots 211. To facilitate quick insertion and fixing of the fixing plate 3 onto the fixed side plate 21 during assembly, a chamfer 212 is provided at the opening of the first insertion slots 211. The chamfer 212 allows for rapid assembly of the fixing plate 3 onto the fixed side plate 21. Each of the two fixed plates 3 is provided with a number of corresponding placement slots 32. The bottom of the placement slot 32 is designed to be an arc shape that matches the shape of the rotating shaft 6. When the rotating shaft 6 is placed in the placement slot 32, the rotating shaft 6 fits against the bottom of the placement slot 32, so that the placement slot 32 will not be subjected to concentrated force and will not be deformed or damaged by pressure.

[0025] like Figure 1 and 2 As shown, the housing 1 includes a bottom cover 13, a top cover 11, and side enclosures 12. The side enclosures 12 have openings at both ends and are respectively covered by the bottom cover 13 and the top cover 11. The top cover 11 includes a cover plate 111 and an edge 112 integrally connected to the cover plate 111 around its perimeter. When the top cover 11 covers the side enclosures 12, the edge 112 covers the side enclosures 12 and abuts against the outside of the side enclosures 12. In this embodiment, the top cover 11 and the bottom cover 13 have the same structure, so there is no need to distinguish between the top cover 11 and the bottom cover 13 during assembly, which is beneficial for rapid assembly.

[0026] like Figure 1 As shown, when the fixing plate 3 is inserted into the fixing side plate 21, the load-bearing base plate 2, fixing plate 3, and fixing side plate 21 form a load-bearing box 4 with an open top. Both fixing plate 3 and fixing side plate 21 are perpendicular to the load-bearing base plate 2. At this time, the lower part of the fixing plate 3 located between the two fixing side plates 21 abuts against the load-bearing base plate 2, and the lower part of the fixing plate 3 located outside the two fixing side plates 21 is flush with the bottom surface of the load-bearing base plate 2. The upper sides of the fixing side plate 21 and the upper sides of the fixing plate 3 are flush with each other and are on the same plane.

[0027] like Figure 1As shown, multiple load-bearing boxes 4 can be set according to the height of the side enclosure 12. In this embodiment, four load-bearing boxes 4 are set up by stacking them vertically. When the load-bearing box 4 is placed on the bottom cover 13, the load-bearing bottom plate 2 is attached to the bottom cover 13, the fixing plate 3 is located on the lower side outside the fixing side plate 21 and abuts against the bottom of the box body 1, and the side of the fixing plate 3 abuts against the inner side of the side enclosure 12; the side of the fixing side plate 21 abuts against the inner side of the side enclosure 12. Since the sides of the fixing plate 3 and the fixing side plate 21 both abut against the inner side of the side enclosure 12, the four load-bearing boxes 4 are vertically aligned, that is, the upper and lower fixing plates 3 and the upper and lower fixing side plates 21 are vertically aligned. In order to improve the load-bearing capacity of the fixing plate 3, the thickness of the fixing plate 3 is set to 0.5 to 3 cm. It can be made by stacking multiple corrugated cardboard to achieve the required thickness. In this embodiment, the thickness is preferably 2 cm. The upper load-bearing box 4 is placed on top of the lower load-bearing box 4. The upper sides of the lower fixing plate 3 and the fixing side plate 21 abut against the load-bearing base plate 2. The upper and lower fixing plates 3 located outside the fixing side plate 21 abut against each other. Thus, when the rotating shaft 6 is placed inside the load-bearing box 4, the weight of the upper load-bearing box 4 is applied to the fixing plate 3 and the fixing side plate 21. Since the upper and lower fixing plates 3 and the upper and lower fixing side plates 21 are in the same vertical direction and are not prone to collapse due to the constraint of the side enclosure 12, the fixing plate 3 can stably support the weight of the rotating shaft 6 and transfer this gravity to the fixing side plate 21 and the load-bearing base plate. At the same time, the thickened fixing plate 3 has better support performance and does not increase the overall volume of the box 1.

[0028] like Figure 3 and 5 As shown, in this embodiment, when longer or more rotating shafts 6 need to be placed, a fixed plate 3 with the same structure can be added between the two fixed plates 3, and an auxiliary side plate 5 can be added between the two fixed side plates 21. A third insertion slot 51 is provided on the lower side of the auxiliary side plate 5, and a fourth insertion slot 33 that mates with the third insertion slot 51 is provided at a corresponding position on the fixed plate 3. This plug-in structure makes assembly more convenient for workers. During transportation, a wooden pallet is placed at the bottom of the carton to facilitate transport and transfer.

[0029] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
