Description

Technical Field

[0001] The present invention relates to the technical field of packaging and transportation, and in particular to a modular transportation packaging box and an assembly and use method thereof. Background Art

[0002] In the logistics and transportation industry, most common logistics boxes are made of one-piece cardboard. Express items are often packaged and transported in cheap paper boxes. However, due to their poor quality and low mechanical strength, these boxes fail to effectively protect the packaged items from crushing or collisions during transportation. It's not uncommon for express items to be damaged by the time they reach customers, causing losses for both express delivery companies and customers. Furthermore, due to their poor quality and fragility, the packaging received by customers has a low reuse rate and is often discarded after a single use, resulting in significant resource waste. High-quality packaging is often costly, making it difficult for express delivery companies and customers to accept or reuse it for other purposes. If used repeatedly as express packaging, it is prone to breakage due to concentrated stress on the edges and corners. If even a single partial breakage occurs, the entire package becomes unusable, rendering its recycling efficiency low relative to its manufacturing cost.

[0003] In order to save space, facilitate transportation, and minimize damage, existing designs typically use an assembly process. For example, the boxes are assembled using a top, bottom, sides, alloy edging grooves, and tripods. The tripods are located at the box's eight corners. The aluminum alloy edging grooves are located at the face-to-face junctions, connecting the bottom and sides, the top and sides, and adjacent sides. However, this type of assembled box, which uses bolts and pins for fastening, has many parts, making assembly and disassembly complex, time-consuming, and labor-intensive. Furthermore, due to the heavy metal components, it is unsuitable for use as a logistics box.

[0004] Furthermore, because existing logistics boxes are simply empty boxes, they must be filled with a large amount of filler to protect and secure the items inside. This filler is often difficult or impossible to recycle, resulting in a significant amount of express delivery waste and failing to achieve the goal of environmentally friendly delivery. Fragile items, in particular, require even greater care when handling. Using filler or other securing methods is not only time-consuming, labor-intensive, and inconvenient, but also prone to accidents due to the numerous uncontrollable factors during transportation. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a modular transport packaging box and an assembly and use method thereof to solve the above-mentioned problems.

[0006] The present invention adopts the following scheme:

[0007] The present application provides a modular transport packaging box, comprising: a box cover and a box bottom, a left side panel and a right side panel, a front panel and a back panel; the box bottom is formed by joining two splicing panels, the box cover is opposite to the two splicing panels and the two have the same size specifications; the left side panel and the right side panel are respectively provided with handles, the front panel and the back panel have the same size specifications, and the front panel and the back panel have the same size specifications and their size specifications are the smallest; the front panel slides along a sealing guide groove formed by the left side panel and the right side panel to be plugged into the box bottom, and the back ... Another sealing guide groove slides to be plugged into the bottom of the box, and any adjacent plates are assembled together with a mortise and tenon structure to form the entire packaging box; the bottom, cover, left side plate and right side plate are respectively provided with airbag mechanisms, and the front plate and rear plate are respectively provided with pad mechanisms, and each airbag mechanism and pad mechanism cooperates with each other inside the packaging box to construct a storage space suitable for placing fragile items; within the storage space, the proportion of the airbag mechanism is much greater than that of the pad mechanism; when in the transportation state, the airbag mechanism is suitable for supporting and confining fragile items in the storage space.

[0008] As a further improvement, the airbag mechanism includes a plastic fixing seat installed on the plate body with a mortise and tenon, and an inflatable airbag arranged on the plastic fixing seat. The inflatable airbag is configured into a pillow-shaped structure. The pillow-shaped structure is connected to the outer peripheral side of the plastic fixing seat in an arc shape on all four sides, and its end surface forms a flat flexible contact plane.

[0009] As a further improvement, at least the inflatable airbags assigned to the box bottom and the box cover act on the fragile items directly in the form of upper and lower abutment via flexible contact planes.

[0010] As a further improvement, during normal transportation of the packaging box, the inflatable airbags assigned to the left and right panels are spaced apart from the fragile items at their flexible contact surfaces to form a movement space.

[0011] As a further improvement, the thickness of the inflatable airbag is more than five times the total thickness of the plastic fixing seat and the plate to which it is attached.

[0012] As a further improvement, the pad mechanism includes a mounting shell and a flexible memory foam layer covering and embedded in the inner end surface of the mounting shell. The mounting shell is mortise and tenon connected to the plate body to which it belongs. The sealing guide groove is opened on the edges on both sides of the inner end surface of the left plate and the right plate. The sealing guide groove extends from top to bottom, and its width is equivalent to the thickness of the side plate.

[0013] As a further improvement, corresponding plug-in grooves are opened on the edges of both sides of the inner end surface of the box bottom. The plug-in grooves are connected to the two sealing guide grooves, and their width is equivalent to the total thickness of the side panels and the pad mechanism.

[0014] As a further improvement, the thickness of the flexible memory foam is the sum of the thickness of the mounting shell and the plate to which it is attached.

[0015] As a further improvement, each plate body is provided with a corresponding mortise and tenon that cooperate with each other; and, an anti-collision corner block is correspondingly clamped at each corner of the packaging box, and the anti-collision corner block is plugged and fixed to each adjacent plate body at the corner, and the outer side surface of the anti-collision corner block is provided with a buffer pad, and the four anti-collision corner blocks arranged on the bottom of the box are correspondingly constructed to form a placement surface supported by the outside world.

[0016] The present application further provides a method for assembling and using a transport packaging box, based on the aforementioned modular transport packaging box, comprising the following steps:

[0017] S1: Assemble two splicing plates on site and install an airbag mechanism on each splicing plate;

[0018] S2: Connect the left and right side panels equipped with handles to the box bottom formed by the two spliced ​​panels through corresponding mortise and tenon joints, and install the airbag mechanism on the two side panels accordingly;

[0019] S3: The front and rear panels are provided with corresponding padding mechanisms, and the front and rear panels are correspondingly plugged into the bottom of the box from top to bottom along the sealing guide grooves defined by the left and right panels;

[0020] S4: The fragile items to be transported are placed centrally in the accommodation space formed by the bottom of the box and the panels, and the fragile items are confined to a position intermediate between the airbag mechanisms provided on the left and right panels;

[0021] S5: Connect the box cover with the airbag mechanism to the four plates with corresponding mortise and tenon joints, and then install the anti-collision corner blocks to form the entire packaging box for transportation.

[0022] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0023] 1. The modular transport packaging box of the present application is formed and manufactured by adopting modular assembled panels, and any adjacent panels are connected by a mortise and tenon structure, which improves the overall convenience of disassembly and assembly, as well as operability.

[0024] 2. The bottom of the box is formed by joining and assembling two splicing boards, and the box cover and the size of the two splicing boards are the same, which improves the splicing flexibility of the box bottom and improves the supporting stress of the box bottom, ensuring the load-bearing stability of the entire packaging box.

[0025] 3. Install the left and right panels on the bottom of the box first. The sealed guide grooves formed by the left and right panels facilitate the insertion and alignment of the front and rear panels from top to bottom to the front and rear sides of the bottom of the box, facilitating the connection and coordination between the surrounding panels and further improving the effectiveness of the mortise and tenon connections between the panels.

[0026] 4. The left and right panels are equipped with handles for users to operate, which helps to quickly define the placement posture of the box bottom or box lid always facing downwards. The bottom and box lid of the larger size specifications and the left and right panels are equipped with airbag mechanisms, and the front and rear panels of the smallest size specifications are equipped with pad mechanisms, thereby forming a storage space inside the packaging box that is conducive to the placement of fragile items.

[0027] 5. The proportion of the airbag mechanism in the accommodation space is much larger than that of the cushion mechanism, ensuring that the airbag mechanism fits more closely with the overall protection of fragile items. In addition, the airbag mechanism supports and limits fragile items within the accommodation space during transportation. The two airbag mechanisms provide tight and flexible contact with fragile items in the up and down directions, and the two airbag mechanisms in the left and right directions and the two air cushion mechanisms in the front and back directions respectively prevent collisions of fragile items, which can significantly improve the convenience and safety of transportation.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Example

[0040] Combine Figures 1 to 7 This embodiment provides a modular transport packaging box, including: a box cover 1 and a box bottom 2, a left side panel 3 and a right side panel 4, a front panel 5 and a rear panel 6.

[0041] The bottom 2 is formed by joining two panels 7, and the lid 1 is positioned above the two panels 7 and has the same dimensions. The left and right panels 3 and 4 are each provided with a handle 8, and the front and rear panels 5 and 6 have the same dimensions, with the front and rear panels 6 being the smallest.

[0042] Among them, the front panel 5 slides along a sealing guide groove 9 formed by the left side panel 3 and the right side panel 4 until it is plugged into the box bottom 2, and the rear panel 6 slides along another sealing guide groove 9 formed by the left side panel 3 and the right side panel 4 until it is plugged into the box bottom 2, and any adjacent panels (specifically the box cover 1 and the box bottom 2, the left side panel 3 and the right side panel 4, the front panel 5 and the rear panel 6) are assembled together with a mortise and tenon structure to form the entire packaging box.

[0043] The box bottom 2, box lid 1, left side panel 3, and right side panel 4 are each equipped with an airbag mechanism 10. The front panel 5 and rear panel 6 are each equipped with a cushioning mechanism 11. These airbag mechanisms 10 and cushioning mechanisms 11 cooperate within the box to create a storage space suitable for fragile items. Within the storage space, the airbag mechanism 10 occupies a significantly larger proportion than the cushioning mechanism 11. When in transport, the airbag mechanism 10 is suitable for supporting and confining fragile items within the storage space.

[0044] The modular transport packaging box mentioned above is formed by using modular assembled panels to form the entire packaging box, and any adjacent panels are connected by a mortise and tenon structure, which improves the overall convenience of assembly and disassembly, as well as the operability. In addition, the box bottom 2 is formed by the joint assembly of two splicing panels 7, and the box cover 1 has the same size specifications as the combination of the two splicing panels 7, which improves the splicing flexibility of the box bottom 2 and improves the supporting stress of the box bottom 2, ensuring the load-bearing stability of the entire packaging box. In addition, the left side panel 3 and the right side panel 4 are first installed on the box bottom 2, and the sealing guide groove 9 formed by the left side panel 3 and the right side panel 4 is conducive to the top-down insertion and alignment of the front panel 5 and the rear panel 6 to the front and rear sides of the box bottom 2, which facilitates the connection and coordination between the surrounding panels and further improves the effectiveness of the mortise and tenon connection between the panels.

[0045] In the above description, the left and right panels 3 and 4 are provided with handles 8 for user operation, thereby facilitating the quick placement of the box bottom 2 or lid 1 in a downward-facing position. Airbag mechanisms 10 are correspondingly provided on the larger-sized box bottom 2 and lid 1, as well as the left and right panels 3 and 4. Furthermore, the smallest-sized box front panel 5 and rear panel 6 are correspondingly provided with cushioning mechanisms 11. This creates a storage space within the box that is conducive to the placement of fragile items. In particular, the proportion of the airbag mechanism 10 within the storage space is significantly greater than that of the cushioning mechanism 11, ensuring that the airbag mechanism 10 more closely fits the overall protection of the fragile items. Furthermore, the airbag mechanism 10 supports and confines the fragile items within the storage space during transport. The two airbag mechanisms 10 provide close and flexible contact with the fragile items in the vertical direction, while the two airbag mechanisms 10 in the left and right directions, as well as the two cushioning mechanisms in the front and back directions, provide collision protection for the fragile items, significantly enhancing the convenience and safety of transportation.

[0046] like Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment, the airbag mechanism 10 includes a plastic mounting base 12 mounted on a corresponding plate body by mortise and tenon joints, and an inflatable airbag 13 disposed on the plastic mounting base 12. The inflatable airbag 13 is configured as a pillow-like structure, with its four sides connected to the outer periphery of the plastic mounting base 12 in an arc shape, and its end surface smoothly forming a flexible contact surface 14. Thus, the pillow-like structure of the inflatable airbag 13 facilitates an arc-shaped connection with the plastic mounting base 12, smoothly forming a flexible member directly on the entire mounting base for contact with fragile items. Furthermore, the flexible contact surface 14 directly acts on the fragile items through a large surface contact, significantly improving overall protective performance.

[0047] In this embodiment, at least the inflatable airbags 13 attached to the bottom 2 and lid 1 directly engage the fragile items via flexible contact surfaces 14. Furthermore, during normal transport of the packaging box, the flexible contact surfaces 14 of the inflatable airbags 13 attached to the left and right panels 3 and 4 are spaced apart from the fragile items to create a space for movement. Due to the dimensional specifications of the individual panels, the accommodation space is minimized in the vertical direction and larger in the front-to-back and left-to-right directions, thereby facilitating the construction of an accommodation space that provides flexible vertical contact for fragile items. Furthermore, the handles 8 of the left and rear panels define the vertical placement of the lid 1 and bottom 2. Along the vertical direction, the fragile items are tightly contacted by the airbag mechanisms 10 on the lid 1 and bottom 2, forming a flexible, position-limiting fixation to prevent them from moving during transport. In order to improve the safety and flexibility of the entire accommodating space, the fragile items are further spaced apart from the airbag mechanism 10 equipped on the left side panel 3 and the airbag mechanism 10 equipped on the right side panel 4, and a movable space is formed between them. In this way, when an accident occurs, the fragile items can overcome the abutting force provided by the airbag mechanism 10 in the upper and lower directions, and have a displacement stroke in the left and right directions, which greatly reduces the harm of direct collision and significantly reduces the phenomenon of transportation damage, thereby improving the product competitiveness of the packaging box.

[0048] Preferably, the thickness of the inflatable airbag 13 is at least five times the combined thickness of the plastic mounting base 12 and its associated plate. Thus, by designing the inflatable airbag 13 to have a multiple thickness, the flexible protection of the accommodation space is greatly enhanced. Obviously, the inflatable airbag 13 is specifically inflated and deflated along the air port, which will not be detailed here.

[0049] Furthermore, in order to provide a larger space for movement between the airbag mechanism 10 of the left side panel 3 and the right side panel 4 and the fragile items placed in the storage space, the inflatable airbags of the airbag mechanism 10 of the left side panel 3 and the right side panel 4 are configured to be half the thickness of the inflatable airbags of the airbag mechanism 10 of the box cover 1 and the box cover 2, thereby correspondingly increasing the effective spacing between the airbag mechanisms in the left and right directions.

[0050] like Figure 6 and Figure 7 As shown, in this embodiment, the pad mechanism 11 includes a mounting shell 15 and a flexible memory foam layer 16 encasing and embedded within the inner end surface of the mounting shell 15. The mounting shell 15 is mortise-and-tenon connected to the plate body to which it belongs. Furthermore, the movable space formed between the pad mechanism 11 and the fragile item is significantly larger than the movable space formed between the left side panel 3 and the rear side panel and the fragile item, and the multiple of the movable space is preferably at least three times. This allows the fragile item to move more freely in the front-to-back direction within the storage space, facilitating emergency braking during transportation (when transporting, the packaging box is placed front-to-back along the driving direction), effectively resolving emergencies during transportation, and significantly meeting the stringent requirements of logistics. The flexible memory foam layer 16 has a slow rebound characteristic, absorbing and decomposing external impacts. It accurately shapes the extrusion profile based on the different hardness and softness of the fragile item, providing a pressure-free fit while providing effective support.

[0051] In this embodiment, the sealing guide grooves 9 are defined on both edges of the inner end surfaces of the left and right panels 3 and 4. These sealing guide grooves 9 extend downward, and their widths are comparable to the thickness of the side panels. Furthermore, corresponding insertion grooves 17 are defined on both edges of the inner end surface of the bottom 2. These insertion grooves 17 communicate with the two sealing guide grooves 9, and their widths are comparable to the combined thickness of the side panels and the cushioning mechanism 11. Thus, by forming guide paths (e.g., sealing guide grooves 9) and joint locations (e.g., cushioning mechanisms 17) on the side panels and bottom 2 that facilitate the top-down insertion and alignment of the front and rear panels 5 and 6, the quick connection between the panels is significantly improved. Furthermore, the left panel 3 (or right panel 4) simply slides along the sealing guide grooves 9. Upon engagement with the cushioning mechanism 11, the left panel 3 and its cushioning mechanism 11 (or right panel 4 and its cushioning mechanism 11) are directly aligned within the cushioning mechanism 17, significantly enhancing lateral compliance between the panels and the sealing performance of the bottom. Correspondingly, another plug-in groove connected to the sealing guide groove is provided on the box cover 1 to achieve a tight connection and fit between the plates.

[0052] Preferably, the thickness of the flexible memory foam is the sum of the thickness of the mounting shell 15 and the plate to which it is attached. Thus, the flexible memory foam plays a corresponding role in protecting fragile items at any time with a considerable thickness, further improving the protection of the storage space.

[0053] like Figure 5 and Figure 7 As shown, in this embodiment, each plate body is provided with a corresponding mortise and tenon (not shown) that cooperate with each other. In addition, an anti-collision corner block 18 is correspondingly connected at each corner of the packaging box. The anti-collision corner block 18 is plugged and fixed to each plate body adjacent to the corner. The outer side of the anti-collision corner block 18 is provided with a cushioning pad, and the four anti-collision corner blocks 18 arranged on the bottom 2 of the box are correspondingly constructed to form a placement surface with external support. The anti-collision corner blocks 18 and their cushioning pads can, on the one hand, realize the corresponding plug-in fixation between each plate body, which is conducive to the rapid assembly and convenient disassembly of the entire packaging box. On the other hand, the bottom 2 of the box is lifted and supported, and can be effectively and stably placed in various types of external environments, and to a certain extent, it can prevent moisture and water from entering the box.

[0054] Furthermore, the anti-collision corner block 18 is provided with a corresponding slot on the three adjacent plates, and the three plates extend relatively raised sides in different directions (such as Figure 5 and Figure 7 As shown), each side is engaged with the corresponding slot to limit the position, so as to achieve stable disassembly and assembly.

[0055] Combine Figures 8 and 9 This embodiment further provides a method for assembling and using a transport packaging box, based on the aforementioned modular transport packaging box, comprising the following steps:

[0056] S1: Assemble two splicing plates 7 on site, and install an airbag mechanism 10 on the splicing plates 7;

[0057] S2: Connect the left and right side panels equipped with handles 8 by mortise and tenon to the box bottom 2 formed by the two splicing panels 7, and install the airbag mechanism 10 on the two side panels accordingly;

[0058] S3: Prepare the pad mechanism 11 on the front plate 5 and the rear plate 6 respectively, and insert the front plate 5 and the rear plate 6 into the box bottom 2 from top to bottom along the sealing guide groove 9 defined by the left and right side plates 3 / 4;

[0059] S4: The fragile items to be transported are placed centrally in the accommodation space formed by the box bottom 2 and the panels, and the fragile items are confined to a position intermediate to the airbag mechanisms 10 provided on ¾ of the left and right side panels;

[0060] S5: Connect the box cover 1 with the airbag mechanism 10 to the four plates with corresponding mortise and tenon joints, and then install the anti-collision corner blocks 18 to form the entire packaging box for transportation.

[0061] The above-mentioned method for assembling and using a transport packaging box adopts a mortise and tenon connection method, which allows the various plate modules to be assembled and combined in sequence quickly and conveniently, realizing free assembly and use. It can be more flexibly assembled into a suitable packaging box according to the size of fragile items, and the box cover 1 can be sealed only after the fragile items are placed, which greatly improves the operability and flexibility of logistics transfer, and the airbag mechanism 10 and the pad mechanism 11 in the internal accommodating space have the effect of all-round flexible protection.

[0062] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
