Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, and in particular relates to a shockproof packaging box. Background Technology

[0002] With the development of the logistics and transportation industry, packaging boxes are widely used in cargo transportation and consignment. However, due to the complex road conditions and variable operating conditions during transportation, packaging boxes are often subjected to vibration and impact, leading to damage to the items inside. Currently, common shock absorption methods include installing shock-absorbing devices at the bottom of the packaging box or placing shock-absorbing materials inside. These methods can effectively mitigate minor vibrations or vertical vibrations to some extent, but their effectiveness is often insufficient under complex transportation conditions, especially in cases of horizontal circumferential vibration, sudden braking, or rapid acceleration.

[0003] Furthermore, when the contents of the packaging box are components, vibration may cause displacement between these components, affecting the integrity and functionality of the product. Current technologies for vibration reduction still have limitations and cannot fully address the complexities of multi-dimensional vibrations. There is an urgent need for a better technical solution to improve the safety and stability of goods during transportation. Utility Model Content

[0004] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects and advantages of the present application more readily apparent.

[0005] This invention proposes a shockproof packaging box that solves the technical problem that existing packaging boxes cannot fully cope with multi-dimensional vibrations. This invention features a packaging box capable of adapting to vibrations in multiple directions.

[0006] This utility model discloses a shockproof packaging box, including a box body, a vertical shock-absorbing mechanism, a bottom cover, and a horizontal shock-absorbing mechanism. The box body has a first receiving cavity inside, and a support plate is provided in the first receiving cavity. The vertical shock-absorbing mechanism is disposed between the support plate and the bottom of the box body to reduce the vertical vibration of the box body. The bottom cover abuts against the box body, and a second receiving cavity is provided inside the bottom cover. The horizontal shock-absorbing mechanism is disposed in the second receiving cavity and is fixedly connected to the bottom of the box body to reduce the horizontal vibration of the box body.

[0007] In some embodiments, the horizontal damping mechanism includes a support plate and four telescopic hinge rods. The support plate is disposed within the second accommodating cavity. The four telescopic hinge rods are respectively disposed around the support plate, with one end of each telescopic hinge rod connected to the support plate and the other end connected to the bottom cover.

[0008] In some embodiments, the telescopic hinge rod has multiple rotating connections along its telescopic direction, and the horizontal damping mechanism further includes multiple first elastic elements. Each pair of adjacent rotating connections is provided with a first elastic element. One end of the first elastic element is connected to one of the rotating connections, and the other end of the first elastic element is connected to another adjacent rotating connection. The first elastic elements provide horizontal telescopic buffering for the telescopic hinge rod.

[0009] In some embodiments, the vertical damping mechanism includes a plurality of first bosses, a plurality of second bosses, and a plurality of second elastic members. The plurality of first bosses are evenly disposed at the bottom of the housing. The plurality of second bosses correspond one-to-one with the first bosses and are disposed on the support plate. One end of the second elastic member is connected to the first boss, and the other end of the second elastic member is connected to the second boss, so as to provide vertical damping.

[0010] In some embodiments, the bottom of the cover has four cylindrical stepped protrusions for rotatably connecting to the four telescopic hinge rods respectively.

[0011] In some embodiments, the support plate is provided with two spaced upper and lower ribs around its perimeter. The ribs are provided with through holes. One end of the telescopic hinge rod is located between the upper and lower ribs and is connected to the telescopic hinge rod by a pin passing through the through hole. The telescopic hinge rod is rotatably connected to the pin.

[0012] In some embodiments, the bottom of the tray is provided with a plurality of rollers for rolling on the bottom cover to facilitate movement of the tray.

[0013] In some embodiments, the tray is provided with multiple threaded holes, and the bottom of the box is provided with multiple connecting holes. Screws pass through the connecting holes and are threadedly connected to the threaded holes to fix the bottom cover to the tray.

[0014] In some embodiments, the shockproof packaging box further includes several rubber hoses and cushioning cotton, with the rubber hoses evenly adhered to the sides and bottom of the box; the cushioning cotton is adhered to the rubber hoses to further enhance the shockproof effect.

[0015] In some embodiments, the shockproof packaging box further includes a lid, which is located on top of the box body to close the box body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model discloses a shockproof packaging box. Through the combination of the box body, vertical shock-absorbing mechanism, bottom cover, and horizontal shock-absorbing mechanism, the shockproof performance of the packaging box in both vertical and horizontal directions is comprehensively improved. The vertical shock-absorbing mechanism, through the setting of a first boss, a second boss, and a second elastic element, provides effective cushioning when the box body is subjected to vertical impact, preventing damage to the internal items due to vertical vibration. The horizontal shock-absorbing mechanism, through the design of a support plate, a telescopic hinge rod, and a first elastic element, effectively absorbs vibration energy when the box body is subjected to horizontal vibration through the transmission of the telescopic hinge rod and the cushioning effect of the elastic element, ensuring multi-dimensional protection of the box body.

[0018] 2. This utility model further enhances the horizontal stability of the pallet by setting a rotating connection structure between the cylindrical stepped protrusion at the bottom of the base cover and the telescopic hinge rod, thus preventing the horizontal shock absorption mechanism from shifting or loosening during operation. The roller design at the bottom of the pallet increases the mobility of the horizontal shock absorption mechanism, allowing it to move freely on the horizontal surface. When a horizontal force is applied externally, the rollers can quickly respond to changes in force through their rotational characteristics, effectively buffering horizontal impacts. By reducing friction, the rollers allow the pallet to move easily, achieving a smooth movement function.

[0019] 3. This utility model achieves further shock absorption by attaching rubber hoses to the sides and bottom of the box and installing cushioning cotton on the rubber hoses. This design not only improves shock absorption but also enhances the overall structural strength of the packaging box, effectively preventing external impacts from directly affecting the internal items and ensuring more reliable protection during transportation.

[0020] 4. This utility model, through its ingenious structural design and the application of multiple shock-absorbing mechanisms, effectively solves the problem of existing packaging boxes being easily damaged by vibration during transportation, making it particularly suitable for long-distance transportation of fragile items requiring high protection. Its multi-dimensional vertical and horizontal shock-absorbing design, along with further enhanced external cushioning protection, gives this invention broad application prospects and significant market value.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0032] This utility model embodiment provides a shockproof packaging box, see reference. Figure 1-8As shown, the shockproof packaging box includes a box body 1, a vertical shock-absorbing mechanism 4, a bottom cover 2, and a horizontal shock-absorbing mechanism 5. The box body 1 has a first receiving cavity 101 inside, and a support plate 6 is installed within the first receiving cavity 101. The vertical shock-absorbing mechanism 4 is located between the support plate 6 and the bottom of the box body 1 to reduce vertical vibration of the box body 1. The bottom cover 2 abuts against the box body 1, and a second receiving cavity 201 is located inside the bottom cover 2. The horizontal shock-absorbing mechanism 5 is located within the second receiving cavity 201 and is fixedly connected to the bottom of the box body 1 to reduce horizontal vibration of the box body 1. The vertical shock-absorbing mechanism 4, located between the support plate 6 and the bottom of the box body 1, can reduce the transmission of vertical vibration through its elastic structure, thereby protecting the items inside the box body 1. The horizontal shock absorption mechanism 5 is located inside the bottom cover 2 of the box body 1. Its main function is to reduce horizontal vibrations. When the packaging box is subjected to impacts from various directions, sudden braking or acceleration, or when the contents of the packaging box are components, the vertical and horizontal shock absorption mechanisms work together to effectively absorb external impact forces, protect the safety of the contents, and effectively prevent changes in the assembly relationship of components. This shockproof packaging box, through the combination of vertical and horizontal shock absorption, significantly improves its shock resistance and reduces damage to the contents caused by vibrations during transportation. This structure also enhances the overall stability of the shockproof packaging box, improves its service life, and increases the protection effect on the contents.

[0033] In some embodiments, the vertical damping mechanism 4 may employ different types of elastic elements, such as air springs or compression springs; the horizontal damping mechanism 5 may also be replaced with other damping solutions, such as hydraulic buffer devices or damping rubber blocks, to meet the needs of different transportation environments.

[0034] Furthermore, the horizontal shock absorption mechanism 5 includes a pallet 501, which is located within the second cavity 201 and connected to the bottom cover 2 via four telescopic hinge rods 502. One end of each telescopic hinge rod 502 is connected to the pallet 501, and the other end is connected to the bottom cover 2. Since the pallet 501 is equipped with telescopic hinge rods 502 on all four sides, it can buffer vibrations in all horizontal directions. This ensures the stability of the packaging box during transportation, shipping, sudden braking, sharp turns, and acceleration. Each telescopic hinge rod 502 can extend or retract when the box 1 is subjected to a horizontal impact, thereby absorbing some of the impact energy, reducing vibration transmission, and decreasing the vibration amplitude of the items inside the box 1 during horizontal movement. This design, through the cooperation between multiple telescopic hinge rods 502 and the pallet 501, provides excellent shock absorption performance, enabling the shockproof packaging box to effectively absorb vibration energy under vibrations in different directions, thus protecting the items from damage.

[0035] Furthermore, the telescopic hinge rod 502 has multiple rotating connecting parts 5021 along its telescopic direction, and a first elastic element 503 is provided between two adjacent rotating connecting parts 5021. One end of the first elastic element 503 is connected to one rotating connecting part 5021, and the other end is connected to another adjacent rotating connecting part 5021, providing horizontal telescopic buffering for the telescopic hinge rod 502. The telescopic hinge rod 502 is connected by multiple rotating connecting parts 5021, and the first elastic element 503 is provided between the rotating connecting parts 5021. When the shockproof packaging box is subjected to horizontal impact, the first elastic element 503 will absorb part of the impact energy through its elastic deformation, thereby reducing the transmission of vibration. The telescopic hinge rod 502 achieves a better buffering effect through multiple first elastic elements 503 and rotating connecting parts 5021, further enhancing its horizontal shock absorption capability. This horizontal shock absorption mechanism greatly improves the shock resistance performance of the shockproof packaging box under multi-dimensional impacts.

[0036] In some embodiments, a pin 7 is used for rotatable connection at the rotating connection 5021, and a cotter pin is inserted into the tail hole of the pin 7 to prevent the pin 7 from slipping. After the cotter pin is inserted into the tail of the pin 7, it effectively prevents the pin 7 from accidentally loosening due to vibration or external force during use, ensuring the stability of the connection. The pin 7 passes through the rotating connection 5021 of the telescopic hinge rod 502 and is connected to the upper and lower ribs 5011, allowing the telescopic hinge rod 502 to rotate freely. A cotter pin is inserted into the tail of the pin 7. When the cotter pin is inserted and bent to fix it, the pin 7 will not fall off due to vibration or external force, thus maintaining the firmness and safety of the connection. This design, by adding a cotter pin to the tail of the pin 7, further improves the reliability of the pin 7 connection and effectively prevents the pin 7 from slipping during use. Especially in shockproof packaging boxes, the addition of the cotter pin can enhance the stability of the overall structure under vibration, ensuring that the shock absorption effect of the packaging box is not affected.

[0037] Furthermore, the vertical damping mechanism 4 includes multiple first protrusions 401, evenly distributed at the bottom of the housing 1, and multiple second protrusions 402 corresponding one-to-one with the first protrusions 401, disposed on the support plate 6. One end of each of the multiple second elastic elements 403 is connected to a first protrusion 401, and the other end is connected to a second protrusion 402, providing vertical damping. This vertical damping mechanism 4, through the combination of multiple second elastic elements 403, first protrusions 401, and second protrusions 402, effectively buffers the vertical vibration of the housing 1. When the housing 1 is subjected to an external impact from the vertical direction, the second elastic elements 403 absorb the impact force through deformation, thereby preventing direct transmission to the support plate 6 and the items inside the housing 1, achieving a vertical damping effect. By using the design of multiple first protrusions 401, second protrusions 402, and second elastic elements 403, the vertical impact force received by the bottom of the housing 1 can be evenly distributed, preventing excessive local vibration and improving the stability and uniformity of the damping effect. This not only protects the items inside the box, but also extends the lifespan of the shockproof packaging box.

[0038] Furthermore, the bottom of the base cover 2 is provided with four cylindrical stepped bosses 202, which are rotatably connected to the four telescopic hinge rods 502 respectively. The cylindrical stepped bosses 202, as fixed components, serve to rotatably connect with the telescopic hinge rods 502, allowing the support plate 501 to move elastically in the horizontal direction while maintaining the stability of the overall structure. The cylindrical design provides flexibility for the rotation of the telescopic hinge rods 502, ensuring that the connection will not experience excessive wear or obstruction when subjected to impact. This design provides a stable connection while allowing the telescopic hinge rods 502 to rotate flexibly, enabling the horizontal shock absorption mechanism 5 to cope flexibly under multi-directional impacts. The cylindrical stepped bosses 202 have a simple and durable structure, effectively reducing manufacturing costs and improving the reliability of the connection.

[0039] In some embodiments, the cylindrical stepped boss 202 may adopt different geometries, such as square or elliptical, to further adapt to specific application requirements. The connection can also be achieved through other forms of rotating brackets or bearings.

[0040] Furthermore, the pallet 501 is provided with two spaced upper and lower ribs 5011 around its perimeter. Each rib 5011 has a through hole 5012. One end of the telescopic hinge rod 502 is positioned between the two ribs 5011 and connected to the telescopic hinge rod 502 via a pin 7 passing through the through hole 5012. The telescopic hinge rod 502 and the pin 7 are rotatably connected. The upper and lower ribs 5011 of the pallet 501 are rotatably connected to the telescopic hinge rod 502 via the pin 7. This design allows for flexible horizontal movement of the pallet 501 while ensuring its stability at the connection point. When the housing 1 is subjected to external horizontal vibration, the pallet 501 can absorb the vibration through the connection between the telescopic hinge rod 502 and the ribs 5011, and the first elastic element 503 provides cushioning, reducing vibration transmission. The design of the upper and lower ribs 5011 effectively improves the connection strength between the pallet 501 and the telescopic hinge rod 502 while maintaining good rotational flexibility. The use of pin 7 simplifies the connection structure, facilitates installation and maintenance, and further enhances the shock absorption effect of the support plate 501 in the horizontal direction.

[0041] Furthermore, the bottom of the pallet 501 is equipped with multiple rollers 8, which roll on the bottom of the bottom cover 2 to facilitate the movement of the pallet 501. The roller design at the bottom of the pallet 501 allows it to roll smoothly inside the bottom cover 2, reducing frictional resistance between the pallet 501 and the bottom cover 2. When the position of the pallet 501 needs to be adjusted, the use of rollers 8 greatly improves the ease of movement, especially when the shock-resistant packaging box is large or heavy, the roller design helps to reduce the operator's workload. This design makes the movement of the pallet 501 more convenient and flexible, and the rollers 8 reduce friction between the pallet 501 and the bottom cover 2, extending the service life of both. It improves the flexibility of pallet 501 adjustment, making the operation of shock-resistant packaging boxes easier in complex transportation environments.

[0042] Furthermore, the pallet 501 has multiple threaded holes 5013, and the bottom of the housing 1 has multiple connecting holes 102. Screws 11 pass through the connecting holes 102 and are threaded into the threaded holes 5013 to securely connect the bottom cover 2 to the pallet 501. The pallet 501 and the bottom of the housing 1 are connected by screws 11. When the bottom cover 2 needs to be fixed to the pallet 501, the screws 11 pass through the connecting holes 102 at the bottom of the housing 1 and connect to the threaded holes 5013 on the pallet 501, thus firmly fixing the pallet 501 to the bottom cover 2. This connection method facilitates installation and disassembly, while ensuring sufficient stability during fixing to prevent the pallet 501 from loosening or shifting during use. The fixing connection method of screws 11 and threaded holes 5013 allows the pallet 501 and the bottom cover 2 to be tightly joined, providing reliable structural support. This design facilitates quick installation or disassembly of the pallet 501 by operators, improving operational convenience and ensuring structural stability under vibration.

[0043] Furthermore, a shockproof packaging box also includes several rubber hoses 9, which are evenly adhered to the sides of the box body 1 and the support plate 6. Cushioning cotton 10 is adhered to the rubber hoses 9 to further enhance the shockproof effect. The rubber hoses 9, acting as a buffer layer, adhere to the sides of the box body 1 and the support plate 6, providing cushioning against external vibrations. The cushioning cotton 10 further covers the rubber hoses 9. When external impact is transmitted to the box body 1, the rubber hoses 9 and the cushioning cotton 10 work together to absorb and disperse vibration energy, thus providing multiple layers of shockproof protection and reducing the probability of vibrations from the box body 1 being transmitted to the internal items. This design effectively enhances the shockproof effect through a multi-layered structure. The elasticity of the rubber hoses 9 and the shock-absorbing properties of the cushioning cotton 10 combine to give the packaging box superior protective capabilities against strong vibrations. It is particularly suitable for long-distance transportation or harsh vibration environments, providing better protection for the items inside the box body 1.

[0044] In some embodiments, the rubber hose 9 can be replaced with other materials, such as silicone hose or polyurethane hose, to adapt to different environmental requirements. The cushioning cotton 10 can also be replaced with sponge or high-density foam material according to shock absorption requirements to provide stronger shock absorption or durability.

[0045] Furthermore, the shockproof packaging box also includes a lid 3, which is located on top of the box body 1 to close the box body 1. The lid 3 is designed to cover and seal the top of the packaging box, protecting the contents inside the box body 1 from external environmental influences such as dust, moisture, or vibration. When the packaging box is closed, the lid 3 is tightly engaged with the box body 1 via a latch or other securing device, ensuring the safety and stability of the contents inside the box body 1 during transportation. The lid 3 can be designed for sealing according to different needs, providing additional protection. This lid 3 design provides extra protection for the packaging box, preventing the contents inside the box body 1 from being affected by the external environment, especially during long-distance transportation or storage, effectively preventing contamination or damage to the items. The use of the lid 3 also enhances the overall security and sealing of the packaging box.

[0046] In some embodiments, a handle may also be provided on the top of the lid 3 of the shockproof packaging box for easy carrying. This handle may be made of a sturdy material and connected to the top of the lid 3 via hinges or fasteners, allowing users to more easily grip and lift the packaging box during transportation or handling. The handle is fixed to the top of the lid 3 via a connecting structure, allowing users to easily lift or move the packaging box. When not in use, the handle can be laid flat on the surface of the lid 3, avoiding space occupation or interference with the stacking of packaging boxes. When handling is required, the handle provides a convenient gripping point, making the handling process more effortless.

[0047] The working process of the above-mentioned shockproof packaging box is as follows:

[0048] When the shockproof packaging box is subjected to vertical vibration during transportation and shipping, the vertical shock absorption mechanism 4 is mainly used to reduce the vibration. When it is subjected to horizontal vibration, the box body 1 drives the pallet 501 to swing and vibrate through the rollers 8. At this time, the telescopic hinge rod 502 buffers the vibration of the entire pallet 501 and the box body 1 through the first elastic element 503 to reduce the vibration. Since the pallet 501 is equipped with telescopic hinge rods 502 on all four sides, it can buffer the vibration in all horizontal directions. When the shockproof packaging box encounters sudden braking, sharp turning, acceleration and other conditions during transportation and shipping, the stability of the shockproof packaging box can be guaranteed. In addition, the rubber hoses 9 and cushioning cotton 10 glued to the inner cavity of the box body 1 and the support plate 6 can also buffer some of the vibration.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
