Description

Technical Field

[0001] This utility model relates to a packaging carton, and more particularly to a modular packaging carton with a carrying tray. Background Technology

[0002] In the logistics and transportation sector, traditional packaging boxes often use wooden crates, corrugated solid wood pallets, and metal containers (such as tin drums and galvanized iron drums) as the basic load-bearing structure. For example, the compression-resistant modular packaging box proposed in publication number CN201721122426.X improves compression resistance through the design of reinforcing ribs and cushioning layers. However, this type of structure is mainly suitable for wooden crates and is difficult to adapt to packaging boxes made primarily of corrugated cardboard. Furthermore, it lacks a structure that allows for conversion between different transportation modes, requiring manual labor or additional equipment for handling.

[0003] Currently, in the packaging cardboard box industry, independent boxes are still used as the carrier for storing goods. During stacking, the bottom of the cardboard box is usually in direct contact with the ground, and it is rarely used in conjunction with pallets. This easily leads to water seepage into the bottom of the cardboard box, causing the goods to become damp. Meanwhile, existing technology CN218704721U discloses a stackable steel pallet structure. While it allows for moderate folding and stacking, its complex structure and overall weight cannot meet the load-bearing requirements of lightweight packaging cardboard boxes.

[0004] Furthermore, existing cardboard boxes are all handled manually when short-distance transfers are required. A few heavier items are handled using trolleys. However, trolleys and pallets lack structural compatibility, leading to reduced space utilization of transport vehicles and the need to repeatedly purchase trolleys and pallets.

[0005] Furthermore, when cardboard boxes are placed on a trolley, they tend to shift due to inertia. If the operator stops abruptly, this can easily cause the boxes to slide or tip over.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a modular packaging carton with a carrying tray, which would have greater industrial value. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a modular packaging carton with a carrying tray.

[0008] This utility model discloses a modular packaging carton with a carrying tray, comprising a carton body, a tray placed below the carton body, wherein: the top surface of the tray has several magnetic strips, and an anti-slip mat is laid on top of the magnetic strips; metal sheets are distributed at corresponding positions on the bottom of the carton body; several support columns are installed on the reverse side of the tray; the top surface of the tray also has receiving grooves; the anti-slip mat has through holes at the positions corresponding to the receiving grooves; when two trays are stacked, the support column of the upper tray is inserted into the receiving groove of the lower tray; the support column has a vertical insertion hole, and a caster wheel assembly is installed in the insertion hole; the caster wheel assembly includes a wheel body, a disassembly base is connected to the wheel body, and a connecting rod is provided on the disassembly base, the connecting rod is connected to the insertion hole; and a buffer strip is attached to the edge of the tray.

[0009] Furthermore, in the aforementioned pallet-type modular packaging carton, the anti-slip mat is a rubber mat, and both the upper and lower surfaces of the rubber mat are provided with anti-slip textures. The anti-slip textures are arrayed diamond-shaped grooves, and the depth of the diamond-shaped grooves is 0.5 to 1.5 mm.

[0010] Furthermore, in the aforementioned pallet-type modular packaging carton, the magnetic strip is a neodymium iron boron permanent magnet strip, the magnetic strips are arranged horizontally at equal distances from each other, and the magnetic strips are adhered to the pallet.

[0011] Furthermore, in the aforementioned pallet-type modular packaging carton, the metal sheet is attached to the outer side of the bottom of the carton, or to the inner side of the bottom of the carton, or embedded in the bottom of the carton.

[0012] Furthermore, in the aforementioned pallet-type modular packaging carton, the metal sheet has a rectangular structure; or, the metal sheet has an elliptical structure; and the metal sheets are arranged vertically at equal distances from each other.

[0013] Furthermore, in the aforementioned pallet-type modular packaging carton, a support device is distributed on the inner side of the carton body. The support device includes a support frame, and the support frame is provided with diagonal bracing rods distributed in a triangular pattern.

[0014] Furthermore, in the aforementioned pallet-type modular packaging carton, the corners of the pallet are rounded.

[0015] Furthermore, in the aforementioned pallet-type modular packaging carton, the edge of the pallet is provided with several cable tie holes, and nylon bushings are installed inside the cable tie holes.

[0016] Furthermore, in the aforementioned pallet-type modular packaging carton, the insertion rod has several expansion strips distributed on it, and the insertion rod is interference-fitted with the insertion hole.

[0017] Furthermore, in the aforementioned pallet-type modular packaging carton, the cushioning strip is an EPDM rubber strip, and the cushioning strip is distributed with several honeycomb-shaped shock-absorbing cavities.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] 1. Features multiple anti-slip positioning designs. Through the magnetic attraction between the magnetic strip and the metal sheet, combined with the friction enhancement effect of the anti-slip pad, a double anti-slip mechanism is formed, which can effectively prevent the carton body from sliding or shifting during transportation, especially suitable for heavy-duty scenarios.

[0020] 2. Modular stacking structure is adopted. The interlocking design of the support columns and receiving slots reduces the vertical space occupied when pallets are stacked, and physical limits prevent lateral slippage, significantly improving the utilization rate of warehouse and transportation space.

[0021] 3. Convertible transport mode. The plug-in installation structure of the caster wheel assembly, combined with the interference fit design of the connecting rods, allows for rapid conversion between the pallet and the transport trolley and the static load-bearing platform, resulting in high loading and unloading efficiency and facilitating short-distance movement.

[0043] 17. Buffer bar Detailed Implementation

[0044] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0045] like Figures 1 to 8The modular, pallet-type packaging carton includes a carton body 1 and a pallet 2 placed beneath it. The unique feature of the pallet 2 is that its top surface is covered with several magnetic strips 3, and an anti-slip mat 4 is laid on top of these strips. This increases the friction coefficient between the pallet 2 and the bottom of the carton body 1, preventing slippage during handling. Simultaneously, metal plates 5 are distributed at corresponding positions on the bottom of the carton body 1. These metal plates 5 can be attracted by the magnetic strips 3, providing proper positioning and restraint when the carton body 1 is loaded with contents. Furthermore, several support columns 6 are installed on the reverse side of the pallet 2, providing adequate support and preventing water accumulation or temperature conduction from below. For ease of storage and stacking, the top surface of the pallet 2 also features receiving grooves 7, with through holes 8 on the anti-slip mat 4 corresponding to these grooves. When two pallets 2 are stacked, the support column 6 of the upper pallet 2 inserts into the receiving groove 7 of the lower pallet 2. This reduces the vertical space occupied during stacking and provides appropriate support column 6 to limit the movement of the pallet 2, preventing it from slipping and falling. Furthermore, during actual manufacturing, the pallet 2 can be made of different materials, such as plastic sheets or iron sheets, depending on the load-bearing requirements.

[0046] Meanwhile, to facilitate proper handling, a vertical insertion hole (not shown in the figure) is provided in the support column 6, and a caster wheel assembly is installed in the insertion hole. Specifically, the caster wheel assembly used in this invention includes a wheel body 9, a disassembly base 10 connected to the wheel body 9, and a connecting rod 11 provided on the disassembly base 10, which is inserted into the insertion hole. Considering the convenience of temporary positioning, the wheel body 9 can be a model with a brake. Thus, a stable connection can be achieved, and when independent storage is required, the caster wheel assembly can be easily removed without affecting the normal use of the tray 2. To facilitate a stable connection, this invention can distribute several expansion strips 16 on the connecting rod 11, and the connecting rod 11 is interference-fitted with the insertion hole. In this way, even if the tray 2 is lifted in the middle, the caster wheel assembly will not accidentally fall off. When it is necessary to separate the caster wheel assembly, it can be pulled out manually by applying force outward. It should be noted that the wheel body 9 adopts a commercially available conventional caster wheel structure configuration, which will not be described in detail here.

[0047] Therefore, pallet 2 can be transformed into a transport cart, reducing the number of times the carton body 1 needs to be handled and achieving convenient transfer. Because of the cooperation between the anti-slip mat 4 and the magnetic strip 3, the carton body 1 will not easily slip off pallet 2. After transportation to its destination, the carton body 1 can be easily stacked and the pallet 2 stored by separating the pallet 2 and the caster wheel assembly.

[0048] Furthermore, this invention features a cushioning strip 17 attached to the edge of the pallet 2. This provides adequate cushioning during stacking and handling, even if there is scraping against the surrounding area, preventing the pallet 2 or the carton body 1 from being subjected to significant external pressure impact.

[0049] In a preferred embodiment of this invention, the anti-slip pad 4 is a rubber pad with anti-slip textures on both its upper and lower surfaces. To improve the anti-slip effect, the anti-slip texture consists of an array of diamond-shaped grooves 12, each with a depth of 0.5 to 1.5 millimeters. This increases the contact area with the bottom of the carton body 1. Simultaneously, the moderate deformation of the diamond-shaped grooves 12 achieves a suitable negative pressure adsorption effect.

[0050] Furthermore, the magnetic strip 3 used in this invention is a neodymium iron boron permanent magnet strip. The magnetic strips 3 are arranged horizontally at equal intervals and are adhered to the tray 2. This provides excellent adsorption capacity. Correspondingly, the metal sheet 5 is adhered to the outer side of the bottom of the carton, or to the inner side of the bottom of the carton, or embedded in the bottom of the carton. The main purpose is to ensure that the magnetic strip 3 can smoothly adsorb the carton body 1 through the metal sheet 5. During manufacturing, the magnetic strip 3 is 1.5 to 3 mm thick. To increase the thickness and improve the adsorption force, several grooves can be made on the upper surface of the tray 2, allowing the magnetic strip 3 to be embedded (adheded) into the grooves, keeping the upper surface of the tray 2 horizontal and without protrusions. Simultaneously, to achieve a larger adsorption area, the metal sheet 5 is rectangular or elliptical in shape. Furthermore, the metal sheets 5 are arranged vertically at equal intervals. Of course, other arrangements can also be used to achieve stable adsorption. Furthermore, when the weight of the cardboard box 1 is relatively small, the anti-slip mat 4 can be omitted, and the magnetic strip 3 and the metal sheet 5 can be used to attract each other.

[0051] In practical implementation, the inner side of the carton body 1 is equipped with a support device, which includes a support frame 13. The support frame 13 contains triangularly distributed diagonal braces 14. This achieves a triangular support structure, effectively transferring stress and preventing improper collapse of the top and side panels of the carton body 1 during stacking. Depending on the size of the carton body 1 and the weight of the contents, it can be made of corrugated cardboard, PC board, or wood.

[0052] Furthermore, the edges and corners of tray 2 are rounded. This avoids sharp protrusions that could scratch the buffer strip 17. The buffer strip 17 is made of ethylene propylene diene monomer (EPDM) rubber, which offers excellent deformation mitigation. Additionally, the buffer strip 17 contains several honeycomb-shaped shock-absorbing cavities. This allows the buffer strip 17 to moderately compress the honeycomb-shaped shock-absorbing cavities upon impact, thus absorbing stress.

[0053] Considering that moderate auxiliary positioning can be achieved after stacking and mass-producing cardboard boxes 1, several cable tie holes 15 can be opened on the edge of the pallet 2. This allows cable ties to be passed through the cable tie holes 15 for binding and positioning. Furthermore, nylon bushings are installed inside the cable tie holes 15 to prevent burrs from scratching the cable ties and to provide lubrication by reducing the coefficient of friction, thus preventing the cable ties from jamming.

[0054] The working principle of this utility model is as follows:

[0055] Cardboard box daily stacking

[0056] The cardboard boxes are placed directly onto the pallet, forming a stable support structure. Thanks to the support columns, they do not directly contact the ground. Furthermore, the cardboard boxes can be stacked to a certain extent.

[0057] Cardboard box handling

[0058] First, insert the caster wheel assembly into the socket in the support column. Then, brake the caster wheels and stack the cartons sequentially on the pallet. During this process, avoid unnecessary displacement of the anti-slip mat.

[0059] Next, if secondary securing is required, cable ties can be used to bind the carton body.

[0060] Then, the carton can be easily moved by pushing the carton itself, thanks to the omnidirectional wheel assembly, without the need for manual handling.

[0061] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0062] 1. Features multiple anti-slip positioning designs. Through the magnetic attraction between the magnetic strip and the metal sheet, combined with the friction enhancement effect of the anti-slip pad, a double anti-slip mechanism is formed, which can effectively prevent the carton body from sliding or shifting during transportation, especially suitable for heavy-duty scenarios.

[0063] 2. Modular stacking structure is adopted. The interlocking design of the support columns and receiving slots reduces the vertical space occupied when pallets are stacked, and physical limits prevent lateral slippage, significantly improving the utilization rate of warehouse and transportation space.

[0064] 3. Convertible transport mode. The plug-in installation structure of the caster wheel assembly, combined with the interference fit design of the connecting rods, allows for rapid conversion between the pallet and the transport trolley and the static load-bearing platform, resulting in high loading and unloading efficiency and facilitating short-distance movement.

[0065] 4. It has appropriate moisture protection. The raised layer formed by the support columns at the bottom of the pallet can isolate water below 10mm from the ground, significantly reducing the risk of moisture damage.

[0066] 5. Overall structural strength optimization: The supporting device enhances the compressive strength of the carton body, effectively preventing stacking collapse.

[0067] 6. The overall structure is simple and can be modified from existing cardboard boxes, making it highly adaptable.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
