Description

Technical Field

[0001] This utility model relates to the field of modular packaging paper boxes, specifically a modular packaging paper box. Background Technology

[0002] With economic development and the continuous improvement of people's living standards, packaging boxes have become a common tool for packaging goods in daily life. Packaging boxes are a general term for containers, materials, and auxiliary materials used according to certain technical methods to protect products during distribution, facilitate storage and transportation, and promote sales. It also refers to the operational activities involving the application of certain technical methods in the process of using containers, materials, and auxiliary materials to achieve the above objectives. Paper boxes have become a common tool for packaging gifts in people's daily lives.

[0003] A search revealed that Chinese utility model patent CN214420981U discloses a modular packaging box, including a base box. The base box has two rows of lower boxes, each row containing two boxes, one in front and one behind. Each box has an upward-facing opening and a lid at its upper opening. The upper side of the base box has two rotating boxes, one on the left and one on the right, corresponding to the two rows of lower boxes. The rotating box on the left is the left rotating box, and the rotating box on the right is the right rotating box. The lower left end of the left rotating box is foldably connected to the upper left end of the base box, and the lower right end of the right rotating box is foldably connected to the upper right end of the base box. A magnet is located on the right side of the left rotating box, and a magnet is located on the left side of the right rotating box. Magnets attract and fix each other. Both the left and right rotating boxes have upward-facing openings, providing multiple independent spaces for storing items. This allows for the categorization and placement of different items, making it convenient for users.

[0004] The technical solution in this application still has shortcomings: the space for placing items is fixed and cannot be flexibly adjusted according to the size of the items, resulting in poor space flexibility. When the magnet weakens or the items are too heavy, the rotating box may accidentally flip over, causing the items to fall or be damaged. Summary of the Invention

[0005] The purpose of this utility model is to provide a modular packaging box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined packaging cardboard box, comprising an outer cardboard box, a storage box, a cover plate, a spring post, and a window. The outer cardboard box has a storage compartment, and the inner wall of the storage compartment has a sliding groove. The outer wall of the storage box has a sliding strip, which is slidably connected to the sliding groove. The outer wall of the outer cardboard box has an opening, and the frame wall of the opening has a side groove. The top of the outer cardboard box has a window, and the cover plate is slidably placed in the window and the side groove. The top of the outer cardboard box has an installation groove, and the spring post is installed in the installation groove. A connecting rod is installed at one end of the spring post, and a fixed moving plate is installed at one end of the connecting rod. The fixed moving plate is located above the window.

[0007] Using the above technical solution, the storage box is slidably connected to the slide rail via a sliding strip, allowing it to be easily slid out or pushed into the placement compartment of the outer cardboard box. This design allows users to flexibly adjust the position of the storage box according to actual needs, facilitating the retrieval and placement of items. Simultaneously, the size of the storage box can be flexibly adjusted according to the internal space of the placement compartment, further improving space utilization and flexibility. After placing items in the storage box, the cover plate is slid into the side groove from the window, blocking the opening and preventing the storage box from slipping out. The spring column in the mounting groove, through a connecting rod, provides a pushing force to the fixed moving plate towards the window, ensuring the fixed moving plate fits tightly against the top of the window, preventing the cover plate from accidentally falling off. When it is necessary to open the cover plate, simply push the fixed moving plate to expose the window, remove the cover plate from the side groove, and open the opening for easy retrieval and placement of items. This prevents the cover plate from opening on its own, causing the storage box to slip and potentially fall or be damaged, further enhancing the stability and safety of the packaging cardboard box.

[0008] Preferably, a magnetic suction plate is installed on the cover plate, and a magnetic suction piece is provided on the side groove.

[0009] Using the above technical solution, the magnetic plate and magnetic sheet attract each other, which strengthens the connection between the cover and the side groove. When the user moves the cover down, the magnetic force will make the cover slide into the side groove more smoothly. After the cover is fully slid in, the tight fit between the magnetic plate and the magnetic sheet will automatically attract and position the cover, without the need for the user to deliberately align or press hard, which greatly improves the user experience.

[0010] Preferably, a handle is provided on the top of the cover plate.

[0011] With the above technical solution, the handle design makes it easy for users to grip and operate the cover. Users can easily pull the cover out of the side groove with a gentle pull, without having to pry it open or find other tools to assist. This design not only improves the convenience of operation, but also ensures the comfort of users during use.

[0012] Preferably, the storage box is provided with a recessed hand groove, and the size of the storage box can be flexibly adjusted according to the internal space of the storage compartment.

[0013] By adopting the above technical solution, the concave hand groove design provides users with a more comfortable grip point when pulling out the storage box, increasing the stability and convenience of pulling out the storage box, and further improving the user experience.

[0014] Preferably, the slide grooves are provided in five groups with equal spacing.

[0015] By adopting the above technical solution, the chute configuration provides multiple adjustable positions for the storage box, allowing users to flexibly choose the placement of the storage box according to actual needs and the size of the items, further improving the flexibility and utilization of space.

[0016] Preferably, the spring post includes a telescopic rod and a spring mounted outside the telescopic rod.

[0017] Using the above technical solution, the spring column includes a telescopic rod and a spring installed outside the telescopic rod. This structural design gives the spring column good elasticity and restoring ability. When the fixed moving plate is subjected to external force, the telescopic rod will extend and retract, and the spring will deform accordingly to absorb and store energy. When the external force disappears, the spring will release the stored energy, push the telescopic rod to reset, and thus drive the fixed moving plate back to its initial position. This design not only ensures that the fixed moving plate can be stably attached to the top of the window, preventing the cover from falling off accidentally, but also ensures the safety of the packaging box.

[0018] Compared with the prior art, the beneficial effects of this utility model are: The storage box is slidably connected to the slide rail via a slider, allowing it to be easily slid out or pushed into the outer cardboard box's storage compartment. This design enables users to flexibly adjust the storage box's position according to actual needs, facilitating the retrieval and placement of items. Furthermore, the size of the storage box can be flexibly adjusted to fit the internal space of the storage compartment, further improving space utilization and flexibility.

[0019] After placing the items in the storage box, slide the cover plate into the side groove from the window to block the opening and prevent the storage box from slipping out. The spring column in the mounting groove, through the connecting rod, provides a pushing force to the fixed moving plate towards the window, ensuring that the fixed moving plate fits tightly against the top of the window and preventing the cover plate from falling off accidentally. When it is necessary to open the cover plate, simply push the fixed moving plate to expose the window, remove the cover plate from the side groove, and open the opening for easy access to items. This prevents the cover plate from opening on its own and causing the storage box to slip, which could lead to items falling or being damaged, further enhancing the stability and safety of the packaging box.

The top of the outer cardboard box 1 has a window 16, and the cover plate 7 is slidably placed in the window 16 and the side groove 17. The top of the outer cardboard box 1 is provided with an installation groove 13, and the spring post 14 is installed in the installation groove 13. A connecting rod 15 is installed at one end of the spring post 14, and a fixed moving plate 9 is installed at one end of the connecting rod 15. The fixed moving plate 9 is located above the window 16. The storage box 5 is slidably connected to the slide rail 3 via the slide bar 4, allowing it to be easily slid out or pushed into the placement compartment 2 of the outer cardboard box 1. This design allows users to flexibly adjust the position of the storage box 5 according to actual needs, making it convenient to retrieve and place items. Meanwhile, the size of the storage box 5 can be flexibly adjusted according to the internal space of the storage compartment 2, further improving the space utilization and flexibility. After placing the items in the storage box 5, the cover plate 7 is slid into the side groove 17 from the window 16, so that the cover plate 7 blocks the opening 10, thereby preventing the storage box 5 from slipping out of the opening 10. The spring column 14 in the mounting groove 13 pushes the fixed moving plate 9 towards the window 16 through the connecting rod 15, so that the fixed moving plate 9 can be tightly attached to the top of the window 16, preventing the cover plate 7 from falling off accidentally. When it is necessary to open the cover plate 7, simply push the fixed moving plate 9 to expose the window 16, take the cover plate 7 out of the side groove 17, open the opening 10, and make it convenient for users to take out and put in items. This avoids the cover plate 7 opening on its own and slipping the storage box 5, causing items to fall or be damaged, further enhancing the stability and safety of the packaging box.

[0024] A magnetic plate 12 is installed on the cover plate 7, and a magnetic piece 11 is provided on the side groove 17. The magnetic plate 12 and the magnetic piece 11 attract each other, which strengthens the connection stability between the cover plate 7 and the side groove 17. When the user moves the cover plate 7 down, the magnetic force will make the cover plate 7 slide into the side groove 17 more smoothly. After the cover plate 7 is fully slid in, the tight fit between the magnetic plate 12 and the magnetic piece 11 will automatically attract and position the cover plate 7, without the user having to deliberately align it or press it hard, which greatly improves the user experience.

[0025] The top of the cover plate 7 is provided with a handle 8. The handle 8 is designed to make it easy for users to grip and operate the cover plate 7. Users can easily pull the cover plate 7 out of the side groove 17 by simply pulling it gently, without having to pry it open or find other tools to assist. This design not only improves the convenience of operation, but also ensures the comfort of users during use.

[0026] The storage box 5 is provided with a recessed hand groove 6, and the size of the storage box 5 can be flexibly adjusted according to the internal space of the storage compartment 2. The design of the recessed hand groove 6 provides users with a more comfortable grip when pulling out the storage box 5, increasing the stability and convenience of pulling out the storage box 5, and further improving the user experience.

[0027] The slide rails 3 are arranged in five sets with equal spacing. The arrangement of the slide rails 3 provides multiple adjustable positions for the storage box 5, allowing users to flexibly choose the placement position of the storage box 5 according to actual needs and the size of the items, further improving the flexibility and utilization of space.

[0028] The spring post 14 includes a telescopic rod and a spring installed outside the telescopic rod. This structural design gives the spring post 14 good elasticity and restoring ability. When the fixed moving plate 9 is subjected to external force, the telescopic rod will extend and retract, and the spring will deform accordingly to absorb and store energy. When the external force disappears, the spring will release the stored energy, pushing the telescopic rod back to its original position, thereby driving the fixed moving plate 9 back to its initial position. This design not only ensures that the fixed moving plate 9 can stably fit above the window 16, preventing the cover plate 7 from accidentally falling off, but also ensures the safety of the packaging box.

[0029] Working principle: The storage box 5 is slidably connected to the slide rail 3 via the slide bar 4, allowing it to be easily slid out or pushed into the placement compartment 2 of the outer cardboard box 1. This design allows users to flexibly adjust the position of the storage box 5 according to actual needs, facilitating the retrieval and placement of items. Simultaneously, the size of the storage box 5 can be flexibly adjusted according to the internal space of the placement compartment 2, further improving space utilization and flexibility. After placing items in the storage box 5, the cover plate 7 is slid into the side groove 17 from the window 16, blocking the opening 10 and preventing the storage box 5 from slipping out. The spring post 14 in the mounting groove 13, through the connecting rod 15, provides a pushing force to the fixed moving plate 9 towards the window 16, ensuring the fixed moving plate 9 is tightly fitted above the window 16, preventing the cover plate 7 from accidentally falling off. When it is necessary to open the cover plate 7, simply push the fixed moving plate 9 to expose the window 16. The cover 7 is removed from the side groove 17, opening the opening 10 for easy access to items. The magnetic plate 12 and magnetic piece 11 attract each other, strengthening the connection between the cover 7 and the side groove 17. When the user moves the cover 7 down, the magnetic force will make the cover 7 slide more smoothly into the side groove 17. After the cover 7 is fully slid in, the tight fit of the magnetic plate 12 and magnetic piece 11 will automatically hold the cover 7 in place, eliminating the need for the user to align it or press it down, greatly improving the user experience and preventing the cover 7 from opening the storage box 5 on its own and causing items to fall or be damaged. This further enhances the stability and safety of the packaging box.
