Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to an anti-mildew packaging box with anti-collision function. Background Technology

[0002] In logistics transportation, warehousing and storage scenarios, packaging boxes, as the core carriers for the protection of goods, need to deal with the two core issues of impact and collision and moisture and mold. In particular, for environmentally sensitive items such as electronic components, precision instruments and textiles, the quality of transportation and storage directly depends on the impact-absorbing performance and mold and moisture-proof capabilities of the packaging boxes. However, existing mold-proof packaging boxes still have certain defects in use.

[0003] As proposed in application number CN202421777981.6, a mildew-proof packaging box for goods belongs to the field of goods packaging technology. It includes a box body with a mildew-proof layer on the inner side. The mildew-proof layer includes an antibacterial layer and a moisture-proof layer. The antibacterial layer is disposed on the inner wall of the box body, and the moisture-proof layer is disposed on the surface of the antibacterial layer. A PE waterproof membrane is adhered to the outer wall of the box body. A sealing cap is installed on the top of the box body, and a fastening mechanism is provided on the sealing cap to fix it to the box body. In actual use, this mildew-proof packaging box achieves mildew prevention through sealing and the mildew-proof layer. However, the mildew-proof layer needs to be replaced periodically, reducing its practicality. Furthermore, the internal space of this mildew-proof packaging box is fixed and cannot be adjusted according to actual needs, reducing its effectiveness.

[0004] Therefore, we propose a mildew-proof packaging box with anti-collision function to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a mildew-proof packaging box with anti-collision function, so as to solve the problems mentioned in the background art that the mildew-proof layer needs to be replaced regularly and that it is inconvenient to adapt and adjust the internal space.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mildew-proof packaging box with anti-collision function, comprising a box body, side handles fixedly installed on the front and rear sides of the box body, a connecting edge fixedly installed on the outer ring of the top of the box body, a top cover movably installed on the top of the box body, a butt edge installed on the outer ring of the bottom end of the top cover, and a positioning connection mechanism connecting the top cover, the butt edge, and the connecting edge.

[0007] Ventilation holes are provided at equal intervals on the left side of the box, and a ventilation and drying mechanism is installed on the right side of the box;

[0008] A telescopic buffer mechanism is installed on the right side of the box;

[0009] The interior of the box is equipped with a space division mechanism.

[0010] Preferably, the positioning and connecting mechanism includes a positioning bolt that passes through the top corner of the mating edge, the bottom end of the positioning bolt being threadedly connected to the connecting edge, and a top handle being fixedly installed on the top surface of the top cover.

[0011] With the above-mentioned structural design, the positioning bolts pass through the mating edge and the connecting edge and are threaded and locked, which can realize the sealed fixation of the top cover and the box body, and prevent the top cover from loosening during transportation. The top handle design makes it easy to disassemble and assemble the top cover, improving the ease of operation. At the same time, the threaded connection has strong stability and can be combined with the overall structure of the box body to enhance the overall anti-collision protection and prevent the top cover from falling off due to impact.

[0012] Preferably, the ventilation and drying mechanism includes a mounting frame embedded in the right side of the housing, with positioning frames installed at equal intervals inside the mounting frame, a support frame fixedly connected to the inner ring of the positioning frame, a drive motor fixedly installed in the middle of the support frame, a fan blade assembly fixedly installed at the shaft end of the drive motor, a filter screen fitted into the inner ring of the right end of the positioning frame, and an energy storage module fixedly installed on the right side of the housing. The energy storage module is connected to the drive motor via a wire.

[0013] The above-mentioned structure design uses an energy storage module to power the drive motor, which drives the fan blade assembly to rotate. This creates air convection inside the box with the ventilation holes on the left side, quickly achieving air circulation, inhibiting mold growth, and solving the problem of limited adsorption capacity and the need for regular replacement of traditional desiccants.

[0014] The positioning frame and support frame provide stable support for the motor and fan blade assembly. The filter screen can block external dust and impurities from entering the cabinet, preventing contamination of internal items or affecting ventilation. Multiple fan blade assemblies are evenly distributed to ensure that the dry airflow evenly covers the inside of the cabinet, providing comprehensive and long-lasting anti-mildew effect.

[0015] Preferably, the telescopic buffer mechanism includes limiting seats symmetrically installed at equal intervals on the right side surface of the housing. A slider is slidably installed inside the limiting seat. A rubber block is connected to the left side of the slider. A connecting rod is symmetrically installed on the right side of the slider. A protective plate is fixedly installed at the right end of the connecting rod.

[0016] Preferably, the connecting rod and the slider form a telescopic structure with the limiting seat through a rubber block, and the protective plate protects the ventilation and drying mechanism.

[0017] With the above-mentioned structure, the slider slides within the limit seat and works with the elastic buffer of the rubber block to form a retractable anti-collision structure. When the box is impacted from the right side, the protective plate first bears the external force and pushes the slider to squeeze the rubber block through the connecting rod. The elastic deformation of the rubber block absorbs the impact energy, greatly reducing the transmission of the impact force to the inside of the box and improving the core anti-collision performance.

[0018] The protective plate also provides physical protection for the ventilation and drying mechanism, preventing external collisions from damaging key components such as the motor and fan blade assembly, and ensuring the continuous operation of the ventilation and drying function.

[0019] Preferably, the space division mechanism includes a fixed plate fixedly installed inside the box body. The box body has equally spaced insertion slots on the front and rear sides. Insertion plates are movably inserted into the insertion slots. A connecting slot is provided in the middle of the insertion plate. The connecting slot is inserted into the fixed plate. The fixed plate and the insertion plate form an internal cross support structure for the box body.

[0020] With the above-mentioned design, the fixing plate and the plug-in plate form a detachable cross support structure through the plug-in slot and the connecting slot. Users can flexibly adjust the plug-in position of the plug-in plate according to the size and quantity of the items, and freely divide the internal space of the box, solving the problem that the internal space of traditional packaging boxes cannot be adapted and adjusted.

[0021] The cross-shaped support structure not only positions the items, reducing shaking and collisions during transportation, but also enhances the structural strength of the container and improves its overall anti-collision performance.

[0022] Preferably, the positioning and connecting mechanism includes limiting rods symmetrically installed on the top surfaces of both ends of the connecting edge, and the limiting rods are slidably connected to the mating edge.

[0023] Preferably, the positioning and connecting mechanism further includes positioning seats symmetrically installed on the top surface of the top cover. A rotating rod is rotatably passed through the interior of the positioning seat. The two ends of the rotating rod are threaded in opposite directions. Sleeves are threaded onto the two ends of the rotating rod. A snap-fit ​​plate is fixedly fitted onto the outer ring of the sleeve. A limit plate passes through the interior of the snap-fit ​​plate. The limit plate is fixedly connected to the positioning seat. The snap-fit ​​plate is slidably connected to the limit plate. The snap-fit ​​plate is movably engaged with the connecting edge.

[0024] The design of the above structure, with the limiting rod slidingly engaging with the mating edge, provides guidance for the top cover docking and ensures the alignment of the top cover with the box body. The reverse thread design at both ends of the rotating rod allows the two sets of sleeves to move synchronously in opposite directions when rotated, thereby driving the snap-fit ​​plate to slide along the limiting plate, achieving quick engagement or disengagement with the connecting edge without the need for bolt locking, making the operation more efficient. The overall structure allows the opening and closing of the top cover to be completed without complicated tools, facilitating the retrieval and placement of items inside the box or the adjustment of the space division structure, taking into account both convenience and protection.

[0025] Compared with the prior art, the beneficial effects of this utility model are: the anti-collision and mildew-proof packaging box has anti-collision function;

[0026] 1. Through the coordinated design of the ventilation and drying mechanism and the space division mechanism, the core pain points of traditional packaging boxes are effectively solved. The ventilation and drying mechanism uses a drive motor to rotate the fan blade assembly, which forms air convection inside the box with the ventilation holes. It can inhibit the growth of mold for a long time without relying on traditional desiccants, and completely avoids the trouble of regularly replacing the anti-mold layer. At the same time, the filter screen can block impurities from entering and ensure stable ventilation and drying effect. The space division mechanism adopts a detachable cross support structure. Users can flexibly adjust the position of the plug plate according to the size and quantity of the items and freely divide the internal space. It not only achieves the adaptation to different items, but also reduces the shaking and collision of items during transportation through positioning, taking into account both practicality and protection.

[0027] 2. The telescopic buffer mechanism utilizes the elastic telescopic cooperation of the slider and rubber block to efficiently absorb external impact energy and significantly reduce the transmission of impact force to the items inside the box. At the same time, the protective plate can protect the key components of the ventilation and drying mechanism. The positioning and connection mechanism offers two options: bolt locking and snap-fit. The bolt connection ensures a stable seal, while the snap-fit ​​design uses a reverse thread design to enable quick opening and closing of the top cover without complicated tools, making operation efficient and convenient. Both structures can enhance the overall connection between the box body and the top cover. Combined with the cross support structure to strengthen the box body, it further enhances the overall anti-collision protection capability of the packaging box. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a mildew-proof packaging box with anti-collision function, including a box body 1, side handles 2 fixedly installed on the front and rear sides of the box body 1, a connecting edge 3 fixedly installed on the top outer ring of the box body 1, a top cover 4 movably installed on the top of the box body 1, a mating edge 5 installed on the bottom outer ring of the top cover 4, a positioning connection mechanism connecting the top cover 4, the mating edge 5 and the connecting edge 3, the positioning connection mechanism including a positioning bolt 6 passing through the top corner of the mating edge 5, the bottom end of the positioning bolt 6 being threadedly connected to the connecting edge 3, and a top handle 7 fixedly installed on the top surface of the top cover 4;

[0038] With the above-mentioned structure, when in use, the operator can lift the top cover 4 through the top handle 7 on the top surface of the top cover 4, align the mating edge 5 of the bottom outer ring of the top cover 4 with the connecting edge 3 of the top outer ring of the box body 1, so that the mating edge 5 is completely in contact with the top surface of the connecting edge 3. Then, the positioning bolt 6 is inserted vertically from the top corner of the mating edge 5, so that the bottom end of the positioning bolt 6 engages with the threaded hole inside the connecting edge 3. By tightening the positioning bolt 6, the self-locking property and fastening force of the threaded connection are used to firmly lock the mating edge 5 and the connecting edge 3, thereby fixing the top cover 4 to the box body 1, avoiding the top cover 4 from loosening and falling off due to vibration and impact during transportation, and at the same time enhancing the overall structural integrity of the packaging box to help improve the anti-collision protection effect.

[0039] When it is necessary to open the packaging box to take out or put in items or adjust the internal space, loosen the positioning bolt 6 in the reverse direction to disengage it from the threaded hole of the connecting edge 3, and then easily lift the top cover 4 through the top handle 7 to complete the disassembly. The side handles 2 on the front and rear sides of the box body 1 can facilitate the operator to move the entire packaging box, or assist in fixing the box body 1 when disassembling and assembling the top cover 4, further improving the ease of operation.

[0040] Ventilation holes 8 are evenly spaced on the left side of the housing 1. A ventilation and drying mechanism is installed on the right side of the housing 1. The ventilation and drying mechanism includes a mounting frame 9 embedded in the right side of the housing 1. Positioning frames 10 are evenly spaced inside the mounting frame 9. A support frame 11 is fixedly connected to the inner ring of the positioning frame 10. A drive motor 12 is fixedly installed in the middle of the support frame 11. A fan blade assembly 13 is fixedly installed at the shaft end of the drive motor 12. A filter screen 14 is fitted into the inner ring of the right end of the positioning frame 10. A power storage module 15 is fixedly installed on the right side of the housing 1. The power storage module 15 is connected to the drive motor 12 by wires.

[0041] The above-mentioned structure is designed so that the power storage module 15, which is fixedly installed on the right side of the housing 1, provides stable power support to the drive motor 12, which is fixed in the middle of the inner ring support frame 11 of the positioning frame 10, through the wire. After the drive motor 12 starts, it drives the fan blade assembly 13 at its shaft end to rotate at high speed. The fan blade assembly 13 maintains stable operation under the stable support of the positioning frames 10 and support frames 11, which are evenly distributed inside the mounting frame 9. During the rotation, a directional airflow is generated. At the same time, the filter screen 14, which is embedded in the inner ring of the right end of the positioning frame 10, filters the outside air that is about to enter the housing 1, blocking dust, impurities and other pollutants from entering, so as to avoid contaminating the internal items or affecting the ventilation effect. The air enters the housing 1 under the action of the fan blade assembly 13, and forms an air convection channel with the ventilation holes 8, which are evenly opened on the left side of the housing 1, to quickly exhaust the air inside the housing. The humidity inside the housing 1 is reduced by continuous air circulation, inhibiting the growth of mold. There is no need to rely on traditional desiccants, which solves the problem of the anti-mold layer needing to be replaced regularly. The mounting frame 9 provides a stable embedded mounting base for the entire ventilation and drying mechanism, ensuring the reliability of the coordinated operation of each component.

[0042] A telescopic buffer mechanism is installed on the right side of the box 1. The telescopic buffer mechanism includes a limiting seat 16 symmetrically installed at equal intervals on the right side surface of the box 1. A slider 17 is slidably installed inside the limiting seat 16. A rubber block 18 is connected to the left side of the slider 17. A connecting rod 19 is symmetrically installed on the right side of the slider 17. A protective plate 20 is fixedly installed at the right end of the connecting rod 19. The connecting rod 19 and the slider 17 form a telescopic structure with the limiting seat 16 through the rubber block 18. The protective plate 20 protects the ventilation and drying mechanism.

[0043] The design of the above structure, with the limiting seat 16 symmetrically installed at equal intervals on the right side surface of the box 1, provides a stable installation base for the entire mechanism. The slider 17 slidably installed inside the limiting seat 16 and the rubber block 18 connected on the left side constitute an elastic buffer assembly. When the right side of the box 1 is subjected to external collision or impact, the protective plate 20 fixedly installed at the right end of the connecting rod 19 first directly bears the external force. The external force is transmitted to the slider 17 through the connecting rod 19, pushing the slider 17 to slide to the left inside the limiting seat 16 and squeezing the rubber block 18. The elastic deformation characteristics of the rubber block 18 are used to convert the impact energy into elastic potential energy. The connecting rod 19 and the slider 17, through the telescopic structure formed by the rubber block 18 and the limiting seat 16, ensure the stability and guidance of the component movement during the buffering process.

[0044] Meanwhile, the protective plate 20 covers the outside of the ventilation and drying mechanism, which can block external collisions, foreign object contact and other direct damage to key components such as the mounting frame 9, drive motor 12, and fan blade assembly 13, ensuring the continuous and stable operation of the ventilation and drying mechanism and achieving the effect of protecting functional components.

[0045] The interior of the housing 1 is equipped with a space division mechanism, which includes a fixed plate 21 fixedly installed inside the housing 1. The interior of the housing 1 has equally spaced insertion slots 22 on the front and rear sides. Insertion plates 23 are movably inserted into the insertion slots 22. A connecting slot 24 is opened in the middle of the insertion plate 23. The connecting slot 24 is inserted into the fixed plate 21. The fixed plate 21 and the insertion plate 23 form an internal cross support structure for the housing 1.

[0046] The above-described structure design features a fixed plate 21 installed inside the box 1, which provides the core support foundation for space division. The equally spaced insertion slots 22 on the front and rear sides of the box 1 provide adjustable mounting points for the insertion plates 23. Users can select the appropriate insertion slot 22 based on the size and quantity requirements of the items to be stored, and insert the insertion plate 23 into the slot 22. Simultaneously, the connecting slot 24 in the middle of the insertion plate 23 aligns with the fixed plate 21, completing the insertion. At this point, the fixed plate 21 and the insertion plate 23 together form a cross-shaped support structure inside the box 1. This structure not only divides the inside of the box 1 into multiple independent and adjustable storage spaces, enabling the classification and positioning of items of different sizes and reducing shaking and collisions during transportation, but also enhances the structural stability and deformation resistance of the box 1 through the cross-shaped support structure, further improving the overall anti-collision protection effect of the packaging box.

[0047] Example 2: Based on Example 1, this utility model adopts the following... Figure 6-7The technical solution shown further discloses that the positioning and connecting mechanism includes limiting rods 25 symmetrically installed on the top surfaces of both ends of the connecting edge 3. The limiting rods 25 are slidably connected to the mating edge 5. The positioning and connecting mechanism also includes positioning seats 26 symmetrically installed on the top surface of the top cover 4. A rotating rod 27 is rotatably inserted inside the positioning seat 26. The two ends of the rotating rod 27 are threaded in opposite directions. The two ends of the rotating rod 27 are threaded with a sleeve seat 28. A snap-fit ​​plate 29 is fixedly fitted on the outer ring of the sleeve seat 28. A limiting plate 30 is inserted inside the snap-fit ​​plate 29. The limiting plate 30 is fixedly connected to the positioning seat 26. The snap-fit ​​plate 29 is slidably connected to the limiting plate 30. The snap-fit ​​plate 29 is movably engaged with the connecting edge 3.

[0048] The above structure is designed so that the limiting rods 25 symmetrically installed on the top surfaces of both ends of the connecting edge 3 provide guidance for the docking of the top cover 4. When the top cover 4 is installed, the docking edge 5 of the bottom outer ring of the top cover 4 is slidably connected to the limiting rod 25, so that the docking edge 5 quickly fits against the top surface of the connecting edge 3, providing a positioning basis for subsequent locking. Then, the positioning seat 26 symmetrically installed on the top surface of the top cover 4 is used as a support carrier. The rotating rod 27 that runs through the inside of the positioning seat 26 is rotated. Since the threads at both ends of the rotating rod 27 are reversed, when it rotates, it will drive the sleeve 28 with threads at both ends to move synchronously towards each other. The sleeve 28 then drives the snap-fit ​​plate 29 fixedly fitted on the outer ring to slide along the limiting plate 30 that runs through the inside of the snap-fit ​​plate 29. Finally, the snap-fit ​​plate 29 and the connecting edge 3 are connected in a movable snap-fit ​​connection. The self-locking property of the reverse threads realizes the stable fixation of the top cover 4 and the box 1, avoiding loosening during transportation.

[0049] When the top cover 4 needs to be opened, the rotating rod 27 is rotated in the opposite direction, and the sleeve 28 drives the snap plate 29 to move in the opposite direction in sync, so that the snap plate 29 is disengaged from the connecting edge 3, and the top cover 4 can be easily lifted. The whole process does not require bolt disassembly and assembly, and the operation is efficient and convenient. At the same time, the cooperation between the limit rod 25 and the snap plate 29 can still ensure the integrity of the connection and help improve the anti-collision protection effect of the packaging box.

[0050] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
