Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation equipment technology, specifically a reusable transport box with shock-absorbing support. Background Technology

[0002] With the continuous development of the logistics and transportation industry, the demand for environmentally friendly, efficient, and recyclable packaging containers is increasing. EPP (expanded polypropylene), as a high-performance environmentally friendly material, is widely used in the manufacture of transport boxes due to its lightweight, pressure resistance, and excellent cushioning properties. Currently, there are various reusable transport boxes based on EPP material available on the market, widely used for the turnover and transportation of goods in the food, pharmaceutical, electronics, and automotive parts industries.

[0003] Existing reusable shipping containers still have certain shortcomings in actual use. Since most shipping containers do not have a dedicated shock-absorbing support structure, the contents are prone to displacement or even damage when encountering vibration or impact during transportation. In particular, when shipping containers are stacked, the lack of an effective buffer connection mechanism between the upper and lower containers causes vibration to be directly transmitted to the lower container, affecting transportation safety. In addition, in order to compensate for the structural deficiencies, it is usually necessary to add disposable cushioning materials such as foam pads and air bags, which reduces the recycling efficiency of shipping containers and increases packaging costs and environmental burden. Utility Model Content

[0004] The purpose of this invention is to provide a reusable transport box with shock-absorbing support to solve the problems mentioned in the background art, such as the lack of effective shock-absorbing structure, significant vibration transmission during stacking, and reliance on additional cushioning materials in current reusable transport boxes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating transport box with shock-absorbing support, comprising a transport box body, wherein the top and bottom of the transport box body are respectively provided with an upper connecting frame and a lower supporting frame, the upper connecting frame is symmetrically provided with strip-shaped bearing protrusions on its long side, and the top of the strip-shaped bearing protrusions is provided with multiple modular shock-absorbing units spaced apart along the length direction, the lower supporting frame is symmetrically provided with supporting grooves matching the strip-shaped bearing protrusions on its long side, and the four corners of the upper connecting frame and the lower supporting frame are provided with recesses, and the interior of the recesses is rotatably connected to connecting parts.

[0006] Preferably, the connector has a connecting shaft inserted through a perforation inside, and the corresponding ends of each pair of connecting shafts are connected by a threaded structure, and an elastic support ring is sleeved on the outside of the connecting end of the connecting shaft.

[0007] Preferably, the upper connecting frame is provided with trapezoidal protrusions at the top four corners, and the lower supporting frame is provided with trapezoidal grooves at the bottom four corners that match the structure of the trapezoidal protrusions.

[0008] Preferably, a threaded ring is welded and fixed on the outer side wall of the connector, and a positioning bolt is inserted into the inside of the threaded ring through a threaded structure, and a positioning screw hole that matches the structure of the positioning bolt is provided on the inner side wall of the recess.

[0009] Preferably, the upper connecting frame and the lower supporting frame are integrally formed with the main body of the transport box, and the width of the upper connecting frame and the lower supporting frame is greater than the outer wall contour of the main body of the transport box.

[0010] Preferably, the inner wall of the main body of the transport box is provided with supporting ribs on all four sides. The supporting ribs are arranged in a wave-like manner and adopt an EPP one-piece molding structure.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: the reusable transport box with shock-absorbing support achieves excellent shock absorption and protection, improves transport stability and safety, reduces reliance on additional cushioning materials, and improves recycling efficiency. This reusable transport box with shock-absorbing support constructs a multi-level linkage shock absorption system through the cooperative structure of the upper connecting frame and the lower supporting frame, combined with the limiting design of the strip-shaped bearing boss and the supporting groove, and the connection of the connecting parts within the recess. This effectively absorbs vibration and impact during transportation. The modular shock-absorbing units further enhance local buffering capacity, making the overall structure more stable and reliable, thereby significantly improving the safety of the transportation process and the economy of reusing the box.

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a reusable transport box with shock-absorbing support, comprising a transport box body 1, an upper connecting frame 2 and a lower supporting frame 3 respectively provided at the top and bottom of the transport box body 1, symmetrically provided with strip-shaped bearing protrusions 4 on the long side of the upper connecting frame 2, the strip-shaped bearing protrusions 4 being an integral structure with the long side of the upper connecting frame 2, multiple modular shock-absorbing units 5 spaced apart along the length direction on the top of the strip-shaped bearing protrusions 4, the shock-absorbing units 5 being made of high-performance elastic polymer materials, such as high-damping rubber or polyurethane foam, symmetrically provided with supporting grooves 6 matching the strip-shaped bearing protrusions 4 on the long side of the lower supporting frame 3, and notches 7 being provided at the four corners of both the upper connecting frame 2 and the lower supporting frame 3, the notches 7... An internal rotating connection 8 is provided, with the inner end of the connector 8 connected to the bottom inner wall of the recess 7 via a pivot pin. This structure allows the main body 1 of the transport box to connect with the lower support frame 3 of the upper transport box 1 via the upper connecting frame 2. At this time, the strip-shaped support boss 4 can be inserted into the corresponding support groove 6 of the lower support frame 3, forming a stable longitudinal limiting and support structure. Simultaneously, in the stacked state, the upper connecting frame 2 and the lower support frame 3 are connected to each other via the connectors 8 in the four corner recesses 7, ensuring alignment between the upper and lower boxes while providing a certain buffer deflection space. Therefore, this structure achieves lateral limiting through the engagement of the strip-shaped support boss 4 and the support groove 6, preventing stacking misalignment. Meanwhile, the modular shock-absorbing unit 5 directly absorbs shocks from the upper... The vibration energy of the container is prevented from being directly transmitted to the interior of the main body 1 of the transport box. The resulting multi-level linkage shock absorption structure not only improves the overall stability and impact resistance during stacked transportation, but also effectively reduces the risk of damage to internal items caused by external vibration. This solves the problems of lack of buffer connection mechanism between upper and lower boxes, direct transmission of vibration to the lower box, and reliance on additional buffer materials in the existing technology, thereby improving transportation safety and recycling efficiency. The connecting parts 8 have connecting shafts 9 inserted through perforations inside, and the corresponding ends of each set of connecting shafts 9 are connected by a threaded structure. The connecting ends of the connecting shafts 9 are fitted with elastic support rings 10, which are placed in the gaps between the connecting parts 8 of the same group. When multiple transport box bodies 1 are stacked, the connecting parts 8 at the four corners of the upper and lower boxes are connected to each other. The connecting shaft 9 passes through the through holes on the connecting parts 8 and is screwed on to fix it, so that a stable mechanical connection is formed between adjacent boxes. At the same time, the elastic support ring 10 is compressed and clamped between the connecting parts 8, and uses its elasticity and retraction performance to provide continuous buffer support force and absorb vertical vibration impact. This structure not only enhances the connection stability between boxes in the stacked state, but also effectively improves the overall vibration resistance. The four corners of the top of the upper connecting frame 2 are also provided with trapezoidal protrusions 11, which are also integral with the upper connecting frame 2. The four corners of the bottom of the lower support frame 3 are provided with trapezoidal grooves 12 that match the structure of the trapezoidal protrusions 11.The tight fit between the trapezoidal protrusion 11 and the trapezoidal groove 12 provides additional lateral limiting function, preventing the box from shifting due to vibration or collision during transportation. This further optimizes the stress distribution between boxes in the stacked state, reduces the risk of localized concentrated stress, and improves the overall safety and reliability of transportation. It also reduces the need for external cushioning materials and improves the recycling efficiency of the transport box. A threaded ring 13 is welded and fixed to the outer side wall of the connector 8, and a positioning bolt 14 is inserted into the threaded structure inside the threaded ring 13. A positioning screw hole matching the structure of the positioning bolt 14 is provided on the inner side wall of the recess 7. When the connector 8 rotates out of the recess 7, the positioning bolt 14 is screwed into the positioning screw hole on the inner side wall of the recess 7 through the threaded ring 13, locking the position of the connector 8 and preventing unnecessary rotation or displacement due to vibration or external forces during transportation. Both the upper connecting frame 2 and the lower supporting frame 3 are integrally molded with the main body 1 of the transport container. The width of the upper connecting frame 2 and the lower supporting frame 3 is slightly larger than the outer contour of the main body 1. This structure ensures both structural strength and good shock absorption performance. The slightly larger width allows the upper connecting frame 2 and the lower supporting frame 3 to form an extended limiting edge when multiple transport containers 1 are stacked. This enhances lateral load-bearing capacity while maintaining alignment of the upper and lower containers, preventing stacking misalignment, and effectively improving the contact stability and support area between adjacent containers. Supporting ribs are provided around the inner wall of the main body 1. These ribs extend in a wavy pattern and are integrally molded using EPP. This structure enhances the compressive strength and elastic cushioning capacity of the internal space of the main body 1, providing auxiliary shock absorption for the loaded goods during transportation.

[0018] Working principle: When using this shock-absorbing and support-equipped circulating transport box, first place the items to be transported into the main body 1 of the transport box, then close the lid and lock it. When stacking is required, the operator aligns the lower support frame 3 of one transport box body 1 with the upper connecting frame 2 of another transport box body 1, and makes the trapezoidal groove 12 and trapezoidal protrusion 11 fit together. At the same time, the strip-shaped bearing protrusion 4 of the lower support frame 3 is inserted into the corresponding support groove 6 of the upper connecting frame 2. During this process, the recesses 7 at the four corners of the two transport boxes correspond to each other, and the connecting parts 8 rotate out from their respective recesses 7 and connect. The connecting shaft 9 passes through the through holes on the connecting parts 8 in sequence and is tightened by the threaded structure. The elastic support ring 10 forms a pre-compression state between the connecting parts 8. Then, the positioning bolt 14 is screwed into the positioning screw hole on the inner wall of the recess 7 through the screw ring 13 to lock the position of the connecting parts 8. As multiple transport boxes are stacked in sequence, the stacking stability is further ensured. After the overall assembly is completed, the transport operation can begin, thus completing a series of tasks.

[0019] 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.
