Description

Technical Field

[0001] This utility model relates to the field of cardboard technology, and more specifically to a modular cardboard container. Background Technology

[0002] As is commonly known, cardboard boxes that are assembled or disassembled like building blocks are modular cardboard boxes, also known as automotive parts boxes. They are mainly used in industrial logistics scenarios. By replacing traditional disposable cardboard boxes, they can be reused many times. The entire box is made of corrugated paper and other materials with inner linings made according to the shape of the goods, and can bear a weight of several hundred kilograms or even several tons.

[0003] The specific steps for modular cardboard assembly are as follows: first, bend both ends of the bottom cardboard; then, splice the bottom cardboard with multiple long strips of cardboard; place long automotive parts into the formed cardboard inner lining compartments; finally, place the modular cardboard box into a pallet; and finally, the pallet side panels and the top lid fit together to form a complete large packaging box for long-distance transportation.

[0004] When the modular cardboard boxes described above carry long parts, the inner lining formed by splicing long cardboard strips does not have an additional limiting structure. Instead, the parts are individually limited by two adjacent long cardboard strips. This results in insufficient support strength for the long cardboard strips, causing them to sway during transportation and affecting the stable placement of the parts. This highlights a certain deficiency in modular cardboard boxes. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, one objective of this utility model is to provide a modular cardboard container to solve the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides a modular cardboard container, comprising a pallet body and multiple strips of cardboard, each strip of cardboard having multiple first limiting grooves, and further comprising: limiting strips, which engage with each of the first limiting grooves in the same width direction of each strip of cardboard; at least three reinforcing strips engaging with each strip of cardboard in the length direction; and multiple fixing grooves engaging with each limiting strip on each reinforcing strip.

[0007] Preferably, the pallet body consists of a load-bearing base plate, side panels, and a lid, wherein the load-bearing base plate is specifically a rectangular structure.

[0008] Preferably, the enclosure panel is adapted to the load-bearing base plate, and the enclosure panel and the load-bearing base plate are assembled and snapped together.

[0009] Preferably, the box cover is specifically two first flip-top box covers and two second flip-top box covers, with each first flip-top box cover located on the wall of the enclosure in the width direction.

[0010] Preferably, each of the second flip-top lids is located on the wall of the enclosure along its length.

[0011] Preferably, each of the limiting strips has a second limiting groove that engages with each of the first limiting grooves.

[0012] Preferably, each of the first limiting grooves is a rectangular structure that is adapted to each of the second limiting grooves.

[0013] Preferably, the pallet body is also provided with a bottom cardboard, and the bottom cardboard has a plurality of first slots opened opposite each other in the width direction, and each of the long strips of cardboard has a second slot opened opposite each other to engage with each of the first slots.

[0014] Preferably, each of the reinforcing strips has a positioning groove that engages with each of the long cardboard strips.

[0015] Preferably, each of the reinforcing strips is a rectangular structure, and each of the fixing grooves is located along the length of each of the reinforcing strips.

[0016] In the above technical solution, the modular splicing cardboard container provided by this utility model has the following beneficial effects: After the long cardboard strips are assembled, multiple limiting strips are engaged with the first limiting groove at the same position in the width direction of each long cardboard strip. Then, multiple reinforcing strips are engaged with the long cardboard strips and engaged with the limiting strips through fixing grooves. This device provides additional fixing and limiting for each long cardboard strip through multiple limiting strips, and connects the limiting strips into a whole with the reinforcing strips. This further improves the stability of the long cardboard strips after being engaged with the limiting strips and the strength of the inner lining formed between the long cardboard strips. It weakens or even avoids the problem that the inner lining formed by splicing long cardboard strips does not have an additional limiting structure and only limits the parts individually through two adjacent long cardboard strips, resulting in insufficient support strength of the long cardboard strips. During transportation, the long cardboard strips may shake, affecting the stable placement of the parts. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution, including the following embodiments:

[0027] Example 1

[0028] Combination Figure 2 , Figure 3 as well as Figure 4 As shown, the pallet includes a pallet body 1 and multiple strips of cardboard 3. Each strip of cardboard 3 has multiple first limiting grooves 3.2. The pallet also includes a limiting strip 4, which engages with each first limiting groove 3.2 in the same width direction of each strip of cardboard 3. Each strip of cardboard 3 has at least three reinforcing strips 5 engaged in the length direction. Each reinforcing strip 5 has multiple fixing grooves 5.2 that engage with each limiting strip 4.

[0029] After the long cardboard strips 3 are assembled, multiple limiting strips 4 are engaged with the first limiting grooves 3.2 at the same position in the width direction of each long cardboard strip 3. Then, multiple reinforcing strips 5 are engaged with the long cardboard strips 3, and simultaneously engaged with the limiting strips 4 through the fixing grooves 5.2. This device uses multiple limiting strips 4 to provide additional fixing and limiting for each long cardboard strip 3, and together with the reinforcing strips 5, connects the limiting strips 4 into a whole, further improving the stability of the long cardboard strips 3 after being engaged with the limiting strips 4 and the strength of the inner lining formed between the long cardboard strips 3. This weakens or even avoids the problem of insufficient support strength of the long cardboard strips when the inner lining formed by the splicing of long cardboard strips does not have an additional limiting structure and only uses two adjacent long cardboard strips to limit the parts individually. During transportation, the long cardboard strips may shake, affecting the stable placement of the parts.

[0030] In this embodiment, the number of limiting strips 4 and reinforcing strips 5 can be three to five. Preferably, the number of limiting strips 4 and reinforcing strips 5 is three. The specific number can be set according to the needs of those skilled in the art. The length of the limiting strip 4 is adapted to the length of the multiple long cardboard strips 3 spliced ​​together. The shape of the limiting strip 4 can be a cylindrical structure or a rectangular structure, etc. Preferably, the limiting strip 4 is a rectangular structure (for easy assembly). The rectangular structure of the limiting strip 4 facilitates splicing and assembly. The reinforcing strip 5 is used to additionally fix the limiting strip 4 and the long cardboard strips 3, improving the stability after the two are engaged. In some embodiments, such as Figure 2 As shown in the diagram, when transporting lightweight automotive parts with long dimensions, there are three reinforcing strips 5, which are symmetrically distributed and snapped together from the center strip cardboard 3 to both sides. In other embodiments, when transporting heavy automotive parts with long dimensions, there are five reinforcing strips 5, which are the same as the number of strip cardboard 3 (correspondingly set). Each strip cardboard 3 is provided with a reinforcing strip 5 to accommodate the heavier automotive parts.

[0031] Example 2

[0032] Combination Figure 3 and Figure 4As shown, this embodiment further describes the pallet body 1 provided in Embodiment 1. The pallet body 1 consists of a load-bearing base plate, side panels, and a lid. The load-bearing base plate is specifically a rectangular structure. The side panels are adapted to the load-bearing base plate and are assembled and snapped together. The lid specifically consists of two first flip-top lids 1.1 and two second flip-top lids 1.2. Each first flip-top lid 1.1 is located on the wall of the side panel in the width direction, and each second flip-top lid 1.2 is located on the wall of the side panel in the length direction. This is prior art. Furthermore, the side panels and the load-bearing base plate are assembled and snapped together, which facilitates disassembly or folding, saves storage space and reduces logistics costs when empty boxes are recycled later. Secondly, the tightly integrated side panels and load-bearing base plate resist bumps and shaking during transportation, preventing separation of the side panels and the load-bearing base plate and further protecting internal parts. The rectangular load-bearing base plate precisely matches the side panels, maximizing the pallet's load-bearing area while adapting to standard logistics pallet sizes, allowing for transport with forklifts and pallet trucks. The lid is directly connected to the side panel wall, forming a continuous protective structure when closed. The modular cardboard container (inner liner) formed by assembling long cardboard strips 3 and bottom cardboard 2 is placed inside the assembled load-bearing base plate, such as... Figure 1 The status is as shown.

[0033] Example 3

[0034] Combination Figure 4As shown, this embodiment is an optimization based on the limiting strip 4 provided in Embodiment 1. Each limiting strip 4 has a second limiting groove 4.1 that engages with each first limiting groove 3.2. Each first limiting groove 3.2 is specifically a rectangular structure, which is adapted to each second limiting groove 4.1. Further, preferably, the first limiting groove 3.2 is a rectangular structure. The rectangular groove opening can restrict the horizontal rotation of the limiting strip 4 and the long cardboard 3 after engagement (when the limiting strip 4 is inside the pallet body 1, its two ends contact the side panels of the pallet body 1, thereby restricting the displacement of the limiting strip 4, further improving the installation stability of the limiting strip 4, and preventing the limiting strip 4 from shaking). At the same time, the contact surface of the groove wall is larger, which can disperse the force of transportation vibration, reduce the risk of loosening at the engagement, and structurally avoid the problems of insufficient support strength and easy shaking of the long cardboard. The first limiting groove 3.2 and the second limiting groove 4.1 are precisely matched, and the gap is small after snapping together, so that the limiting strip 4 and the long cardboard 3 form a rigid connection. The two are equivalent to a whole to bear the force, which further enhances the support strength of the inner grid formed between the long cardboard 3. The rectangular structure can quickly align the grooves during assembly, avoiding the limiting strip 4 from being installed backwards or crookedly, reducing the error rate of manual assembly. In addition, the rectangle is a standard shape in industrial structures, which is easy to process and easy to control the dimensional accuracy. It can ensure that the grooves between the limiting strips 4 and long cardboard 3 of different batches can be precisely matched, improving the versatility of parts. The length direction of the rectangular groove can be consistent with the length direction of the long cardboard 3. After snapping together, it can provide continuous support along the length direction of the part, better adapting to the load-bearing requirements of long parts.

[0035] Example 4

[0036] Combination Figure 3As shown, this embodiment further describes the structure and installation of the long cardboard 3 provided in Embodiment 1. A bottom cardboard 2 is also provided on the pallet body 1. Multiple first slots 2.1 are formed opposite each other in the width direction of the bottom cardboard 2. Each long cardboard 3 has a second slot 3.1 that engages with each of the first slots 2.1. Furthermore, after the first slots 2.1 and second slots 3.1 are precisely engaged, they form a concave-convex interlocking structure (interlocking to prevent detachment). Compared to simple flat bonding or adhesive, this simultaneously restricts the translational movement of the long cardboard 3 in the width direction and its detachment in the vertical direction of the bottom cardboard 2. This prevents the long cardboard from shifting or loosening during transport bumps. The multiple slots are evenly distributed along the width direction, resulting in more contact points after engagement. This disperses the weight of the parts and the vibration force during transport onto multiple slots, preventing cardboard deformation caused by excessive force at a single point, and indirectly enhancing the support of the inner lining for long parts. To ensure stability, during assembly, simply align the second slot 3.1 of the long cardboard 3 with the first slot 2.1 of the bottom cardboard 2 and insert it to quickly complete the positioning. At the same time, the position and size of the slots are fixed, which can prevent the long cardboard from being installed crookedly or with incorrect spacing, and ensure the consistency of the dimensions of the inner lining compartments (such as the uniform width and depth of each inner lining compartment to match the specifications of the parts). Multiple slots are distributed along the width direction of the bottom cardboard 2. According to the size requirements of the parts, different slots can be selected to engage with the long cardboard 3, and the number and spacing of the inner lining compartments can be flexibly adjusted (for example, if a wider part needs to be placed, the number of long cardboard 3s can be reduced and the slot spacing can be increased), improving the versatility of the packaging. The number of the first slots 2.1 and their distribution spacing (this spacing is the spacing of the inner lining compartments after being engaged and assembled with the long cardboard 3) can be set according to the needs of those skilled in the art.

[0037] Example 5

[0038] Combination Figure 4 As shown, each reinforcing strip 5 has a positioning groove 5.1 that engages with each strip of cardboard 3. Each reinforcing strip 5 is specifically rectangular in structure, and each fixing groove 5.2 is located along the length of each reinforcing strip 5. Further, preferably, the reinforcing strip 5 adopts a rectangular structure, and its positioning groove 5.1 is adapted to engage with the strip of cardboard 3. The fixing groove 5.2 is arranged along the length and engages with the limiting strip 4. This achieves precise positioning and cross-fixation of the reinforcing strip 5, the strip of cardboard 3, and the limiting strip 4, forming a three-dimensional and stable inner lining frame. It also disperses the load through surface contact and simplifies processing and assembly. At the same time, it can accommodate different numbers of limiting strips 4 and strips of cardboard 3, improving the versatility and structural durability of the overall modular cardboard and preventing the strips of cardboard 3 and the limiting strip 4 from shaking and shifting during transportation.
