[0001] This utility model belongs to the field of plastic packaging box technology, and more specifically, it relates to a modular plastic packaging box. Background Technology

[0002] Plastic packaging boxes, made of plastic, serve as containers for various goods. During storage and transportation, they protect goods from damage, aid in transport, and are reusable, making them widely applicable in industrial production, commercial sales, and logistics. However, when traditional plastic packaging boxes are damaged during use, they must be replaced entirely. Even if some parts of the old boxes remain intact, they are often discarded. This replacement method directly increases packaging procurement costs, including the cost of purchasing new boxes. Furthermore, discarding old boxes entirely renders some intact parts unusable, leading to a waste of plastic raw materials. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a modular plastic packaging box, which solves the problem that traditional plastic packaging boxes need to be replaced entirely when damaged, thus increasing procurement costs and wasting plastic raw materials.

[0004] The purpose and function of this modular plastic packaging box are achieved by the following specific technical means: A modular plastic packaging box includes a box bottom and a box frame. The box frame is frame-shaped and is disposed on the box bottom. The box bottom has four sets of positioning grooves corresponding to the bottom end of the box frame. The bottom end of the box frame passes through the four sets of positioning grooves. A first box panel is replaced on two opposite sides of the box frame, and a second box panel is replaced on two adjacent sides of the box frame. When two sets of first box panels and two sets of second box panels are installed on the box frame, the first box panels and the second box panels are connected by limiting pins. The box frame also has a box cover. The bottom end of the box cover has an installation groove, through which the box cover is detached and mounted on the top of the box frame.

[0005] The above technical solution further includes that each of the four corners of the box frame is provided with a positioning mounting post, and the positioning mounting post is provided with a mounting slot. The first box plate and the second box plate are provided with a first card plate and a second card plate on both sides. When the first box plate and the second box plate are installed on the box frame, the two adjacent first card plates and the second card plates contact each other and are locked in the same set of mounting slots.

[0006] The above technical solution further includes that a through groove is formed through the first card plate, and an assembly hole is formed on the side of the second card plate near the first card plate corresponding to the through groove. The limiting pin passes through the through groove and is inserted into the assembly hole, and the limiting pin is provided with a foldable pull ring.

[0007] The above technical solution further includes that a first auxiliary fixing groove is provided on two adjacent sides of the positioning and mounting column, and a second auxiliary fixing groove is provided on the side of the first box plate and the second box plate near the positioning and mounting column, corresponding to the first auxiliary fixing groove. When the first box plate and the second box plate are installed on the box frame, the same set of fixing members are disassembled and passed through the first auxiliary fixing groove and the second auxiliary fixing groove.

[0008] The above technical solution further includes that a lifting groove is provided in the center of the side of the first box plate away from the box frame, and a force application handle is disassembled in the lifting groove.

[0009] The above technical solution further includes that each of the two sets of second box plates is provided with two sets of assembly slots, and each of the two sets of assembly slots is movably provided with an L-shaped locking fastener. The two sides of the box cover are provided with buckle grooves corresponding to the two sets of locking fasteners on the second box plate. When the second box plate and the box cover are installed on the box frame, the locking fasteners are fastened in the buckle grooves.

[0010] The above technical solution further includes that the top of the box cover is provided with a mating groove, and the bottom of the box is provided with a contact pad corresponding to the mating groove, and the contact pad can be fitted into the mating groove of another set of box covers.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. Modular plastic packaging boxes utilize a detachable structure consisting of the box bottom, frame, first panel, second panel, and lid, allowing for independent replacement of each component. When a box is damaged, it is not necessary to replace the entire box; only the damaged panel, frame, or lid needs to be replaced. This reduces the need for purchasing new boxes as a whole, lowering packaging costs. It also avoids discarding intact parts along with the damaged box, reducing waste of plastic materials, and eliminates the need for disposing of old boxes during replacement, further controlling resource consumption.

[0012] 2. The modular plastic packaging box's components are assembled and disassembled flexibly through positioning slots, limiting pins, and mounting slots. Positioning mounting posts at the four corners of the box frame cooperate with the locking plates on the box panels to ensure installation stability. The box lid connects to the box frame via mounting slots, and the bottom contact pad can fit into the groove of another box lid for easy stacking and storage. Furthermore, the handle on the first box panel facilitates handling, and the locking fasteners on the second box panel secure the lid's position. This improves the packaging box's assembly efficiency, enhances convenience during use, adapts to different storage and transportation scenarios, and extends its overall service life.

Detailed Implementation

[0018] The 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 the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0019] Example

[0020] like Figures 1 to 4As shown, this utility model provides a modular plastic packaging box, including a box bottom 1 and a box frame 2. The box frame 2 is frame-shaped and is disposed on the box bottom 1. The box bottom 1 has four sets of positioning grooves corresponding to the bottom end of the box frame 2, and the bottom end of the box frame 2 passes through the four sets of positioning grooves. A first box panel 101 is replaced on two opposite sides of the box frame 2, and a second box panel 102 is replaced on two adjacent sides of the box frame 2. When the two sets of first box panels 101 and two sets of second box panels 102 are installed on the box frame 2, the first box panels 101 and the second box panels 102 are connected by limiting pins 103. The box frame 2 is also provided with a box cover 3. The bottom end of the box cover 3 has an installation groove, and the box cover 3 is detached and installed on the top of the box frame 2 through the installation groove. The four sets of positioning grooves on the box bottom 1, with the bottom end of the box frame 2 passing through the positioning grooves, can fix the position of the box frame 2 on the box bottom 1 and prevent the box frame 2 from shifting during use. Two sets of first box panels 101 and two sets of second box panels 102 are respectively installed on opposite and adjacent sides of the box frame 2 and connected by limiting pins 103, allowing the first box panels 101 and second box panels 102 to connect and form a complete box structure, preventing the box from falling apart during the storage and transportation of goods. The box lid 3 is installed at the top of the box frame 2 through a bottom mounting groove, covering the top of the box to protect the internal items, while ensuring the stability of the connection between the box lid 3 and the box frame 2, preventing the box lid 3 from falling off during transportation.

[0021] Both the first box panel 101 and the second box panel 102 are replaceable. If either the first box panel 101 or the second box panel 102 is damaged, the entire packaging box does not need to be replaced; only the damaged first box panel 101 or the second box panel 102 needs to be replaced. The box frame 2 and the box bottom 1 are separate structures. If the box frame 2 or the box bottom 1 is damaged, the corresponding part can also be replaced individually. The box cover 3 is detachably connected to the box frame 2 via a mounting slot. If the box cover 3 is damaged, it can be directly removed and replaced with a new box cover 3. This independent replacement method reduces the need for overall replacement, lowers the procurement costs incurred by overall replacement, and also reduces component waste.

[0022] The lid 3 is detachably connected to the frame 2 via a mounting slot. When not in use, the lid 3 can be removed from the top of the frame 2 and stored separately. The first panel 101 and the second panel 102 are connected by a limiting pin 103. After removing the limiting pin 103, the first panel 101 and the second panel 102 can be removed from the frame 2. The bottom end of the frame 2 passes through a positioning groove in the bottom 1 of the box. Applying external force can separate the frame 2 from the bottom 1 of the box. After all components are disassembled, they can be stacked to reduce space occupation and facilitate the storage of empty boxes. At the same time, more disassembled components can be accommodated in a single transport, improving transport efficiency and reducing transport costs.

[0023] Each of the four corners of the frame 2 is equipped with a positioning mounting post 201, and the positioning mounting post 201 has a mounting slot. The first box panel 101 and the second box panel 102 each have a first clamping plate 202 and a second clamping plate 203 on both sides. When the first box panel 101 and the second box panel 102 are installed on the frame 2, two adjacent first clamping plates 202 and second clamping plates 203 contact each other and are secured in the same set of mounting slots. After contact, the adjacent first clamping plates 202 and second clamping plates 203 are fixed together in the slots, which restricts the horizontal displacement of the first box panel 101 and the second box panel 102, preventing the box panels from detaching from the frame 2 during use, ensuring the integrity of the box structure when carrying or transporting goods, and reducing box deformation caused by loose connections.

[0024] The mounting slots of the positioning mounting posts 201 provide clear assembly positions. The first mounting plate 202 and the second mounting plate 203 must be inserted into the corresponding slots to complete the installation. This structure eliminates the need for repeated adjustments to the box panel positions during assembly, allowing for quick alignment of the box panel and the connection points between the box panel and the frame 2, thus shortening assembly time. Simultaneously, the contact between the mounting plates of adjacent box panels within the slots helps to calibrate the connection angles between the box panels, ensuring a smooth joint on all sides of the box and preventing gaps.

[0025] like Figures 1 to 3 As shown, a through slot is formed on the first card plate 202, and an assembly hole is formed on the side of the second card plate 203 near the first card plate 202 corresponding to the through slot. A limiting pin 103 passes through the through slot and is inserted into the assembly hole, and the limiting pin 103 is equipped with a foldable pull ring. The limiting pin 103 passes through the through slot of the first card plate 202 and then into the assembly hole of the second card plate 203, which can fix the adjacent first card plate 202 and second card plate 203 together. This connection method restricts the relative movement of the two card plates, avoids gaps or separation between the first card plate 101 and the second card plate 102 during use, ensures the stability of the side structure of the box, and reduces the risk of items falling or damage to the box due to loose card plates. The foldable pull ring on the limiting pin 103 allows the pin to be quickly pulled out by applying force through the pull ring during disassembly without the need for additional tools. During installation, the limit pin 103 can be directly inserted into the through slot and assembly hole, which is simple to operate and shortens the disassembly and assembly time of the first box plate 101 and the second box plate 102, making it convenient for subsequent component replacement or box disassembly and storage.

[0026] like Figures 1 to 3As shown, the positioning mounting post 201 has a first auxiliary fixing groove on each of its two adjacent sides. The first box panel 101 and the second box panel 102, near the positioning mounting post 201, each have a second auxiliary fixing groove corresponding to the first auxiliary fixing groove. When the first box panel 101 and the second box panel 102 are installed on the box frame 2, the same set of fixing members 401 are detachably inserted into the first and second auxiliary fixing grooves. After the first and second auxiliary fixing grooves align, the fixing members 401 are inserted into the two sets of grooves, providing additional fixing force at the connection between the box panel and the positioning mounting post 201. This supplements the connection between the clamping plate and the mounting groove, further limiting the displacement of the box panel in the vertical and horizontal directions, preventing the box panel from loosening or shifting due to pressure from items or vibrations during transportation, ensuring the overall structure of the box remains stable when carrying heavy items, and reducing the risk of component deformation.

[0027] The fastener 401 is designed for disassembly. When the box panel needs to be disassembled, the fastener 401 can be removed directly without damaging the positioning mounting post 201 or the box panel structure. This strengthens the connection stability through the fastener 401 without sacrificing the disassembly and assembly characteristics of the modular packaging box. Damaged first box panel 101, second box panel 102 or positioning mounting post 201 can still be easily replaced in the future without having to replace the entire component due to the fixed structure, thus reducing maintenance difficulty and cost.

[0028] A lifting groove is provided in the center of the first box panel 101 on the side away from the box frame 2, and a force-applying handle 501 is detachably installed in the lifting groove. The force-applying handle 501 is located in the lifting groove, and the box can be moved by directly gripping the force-applying handle 501 during handling. There is no need to find other parts of the box to apply force, avoiding the box tilting due to improper grip position, reducing the risk of items falling out of the box, and reducing friction between the hand and the box surface during handling, thus improving the convenience of operation. The force-applying handle 501 is detachable and can be removed from the lifting groove when not in use, preventing the handle from protruding from the box surface, reducing the space occupied when the boxes are stacked, and facilitating the stacking and storage of multiple boxes. At the same time, the lifting groove only serves as a handle installation position and does not damage the overall structure of the first box panel 101, ensuring that the load-bearing and protective functions of the box panel are not affected.

[0029] Each of the two sets of second box panels 102 has two sets of assembly slots, and each set of assembly slots has an L-shaped locking fastener 601 that is movably installed in the two sets of assembly slots. The sides of the lid 3 have corresponding locking grooves for the two sets of locking fasteners 601 on the second box panels 102. When the second box panels 102 and the lid 3 are installed on the box frame 2, the locking fasteners 601 engage in the locking grooves. The locking fasteners 601 engaging in the locking grooves restrict the movement of the lid 3 at the top of the box frame 2. This prevents the lid 3 from detaching from the box frame 2 due to vibration or tilting during transportation or handling, ensuring the box remains closed at all times, preventing internal items from falling out, getting damp, or getting dusty, and maintaining the integrity of the items during storage and transportation. Simultaneously, the two sets of locking fasteners 601 act on both sides of the lid 3, ensuring balanced force on the lid 3 and further improving the fixing effect.

[0030] The locking fastener 601 is movably located within the assembly slot, allowing for opening and closing without additional tools. To open the lid 3, simply move the locking fastener 601 out of the slot to remove the lid 3. To close the lid 3, align the lid 3 with the top of the frame 2, push the locking fastener 601 into the slot, and secure it. The entire process is simple, reducing the opening and closing time of the lid 3, making it particularly suitable for scenarios requiring frequent item handling and minimizing operational time.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the top of the box lid 3 has a mating groove, and the bottom of the box bottom 1 has a contact pad 701 corresponding to the mating groove. The contact pad 701 can be fitted into the mating groove of another set of box lids 3. The contact pad 701 fitting into the mating groove of another set of box lids 3 can limit the relative displacement of the upper and lower sets of packaging boxes. This prevents the boxes from sliding due to vibration or tilting during stacking, prevents the stacking structure from collapsing, and ensures that multiple sets of boxes remain neat when stacked, reducing space waste and adapting to the needs of dense warehouse storage. The contact pad 701 fitting into the mating groove can also reduce direct collision between the upper and lower boxes, reduce wear on the surface of the boxes during stacking, extend the service life of the packaging boxes, and reduce external pressure on the contents of the lower box, preventing damage to the contents due to stacking stress.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
