Description

Technical Field

[0001] This utility model relates to the field of cargo transportation equipment technology, specifically a turnover box for cargo transportation. Background Technology

[0002] In the modern freight transportation industry, turnover boxes are widely used as standardized loading tools because of their ease of handling and reusability.

[0003] A search revealed CN220865947U, a cargo transport turnover box. This cargo transport turnover box includes a box body, which is open-top. A positioning groove is provided on the top of the side wall of the box body, and a positioning protrusion is provided on the bottom of the box body at a position corresponding to the positioning groove. The shape of the positioning protrusion matches the shape of the space within the positioning groove. A locking groove is also provided on the top of the side wall of the box body, containing a locking hole. The lock also includes a latch, which consists of a latch plate and a latch post disposed on the latch plate. The shape of the latch post matches the shape of the locking hole. Through the matching positioning post and positioning groove, when the turnover boxes are stacked, the positioning post of the upper turnover box can be embedded into the positioning groove of the lower turnover box, preventing displacement between the upper and lower turnover boxes and greatly increasing the stability between the upper and lower turnover boxes during transportation.

[0004] The aforementioned device, by setting positioning posts at the top and positioning grooves at the bottom of the turnover boxes, allows the positioning posts of the upper turnover boxes to be embedded in the positioning grooves of the lower ones, thereby avoiding horizontal displacement between the upper and lower turnover boxes to a certain extent and ensuring the stability of the stacking foundation. However, the actual transportation environment is complex and changeable. Sudden braking of vehicles, road bumps, and cargo collisions occur frequently during transportation. When such collisions occur, the cooperation of positioning posts and positioning slots alone cannot effectively resist horizontal impact forces. The upper turnover box is very likely to tip over due to imbalance of forces, which may not only damage the goods inside the box, but also cause a large-scale collapse of the goods inside the transport vehicle, seriously affecting transportation safety and efficiency.

[0017] 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.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-3 As shown, this utility model is a turnover box for cargo transportation, comprising: Box 11; The stacking component includes a second box 21, a first bottom plate 22, a second bottom plate 23, a first top cover 24, and a second top cover 25. The first bottom plate 22 is fixed to the bottom of the first box 11, the second bottom plate 23 is fixed to the bottom of the second box 21, the first top cover 24 is suspended from the top of the first box 11, and the second top cover 25 is suspended from the top of the second box 21. The limiting component includes an inner groove 31, a rotating shaft 32, a vertical plate 33, and a snap-fit ​​groove 35. The inner groove 31 is opened on the top of the first top cover 24 and the second top cover 25. The rotating shaft 32 is set at one end of the inner surface of the inner groove 31. The vertical plate 33 is rotatably connected to the outer surface of the rotating shaft 32. The snap-fit ​​groove 35 is opened at both ends of the outer surface of the second bottom plate 23. The upper part of the vertical plate 33 is snapped into the inside of the snap-fit ​​groove 35. The upright plate 33, which can be rotated, unfolded, or folded, cooperates with the locking groove 35. When the second box 21 is stacked on top of the first box 11 and the upright plate 33 is unfolded and locked into the locking groove 35, a multi-dimensional limiting and fixing structure can be formed. This not only restricts horizontal displacement, but also effectively disperses and offsets external forces when impact occurs due to collision. The locking action of the upright plate 33 and the locking groove 35 greatly reduces the risk of the upper turnover box tipping over and provides a more reliable safety guarantee for cargo transportation.

[0020] A top block 34 is fixedly connected to the top of the upright plate 33, and the second box 21 is located above the first box 11.

[0021] It also includes a fixing component, which includes a support frame 41, a slide groove 42 and a slider 45. The support frame 41 is located on the upper part of the outer surface of the second box 21, the slide groove 42 is opened on the upper part of both sides of the outer surface of the second box 21, and the slider 45 is arranged on both sides of the inner surface of the support frame 41 and is movably connected to the inside of the slide groove 42. The slider 45 slides inside the groove 42, causing the support frame 41 to move up and down.

[0022] The inner surface of the support frame 41 has two end openings for snap fastening grooves 44, which are embedded in the outer surface of the top block 34. When the support frame 41 moves to the lower part, the top block 34 will be engaged inside the fastening groove 44 to reinforce the position of the inlaid upright plate 33.

[0023] A slot 43 is provided at the lower part of the inner surface of the slide groove 42, and an insert 46 is provided at the bottom of the slider 45, which is inserted into the slot 43. Insert 46 is inserted into the slot 43 to fix the position of the support frame 41 after it has been moved.

[0024] Working principle: During the stacking of turnover boxes, when box 21 needs to be stacked on top of box 11, box 21 is first aligned with box 11 to initially align their positioning structures. Then, the upright plate 33 is rotated, and using the connection between the upright plate 33 and the rotating shaft 32, the upright plate 33 is rotated and unfolded from the folded state. After unfolding, the upright plate 33 is precisely engaged in the locking groove 35. At this time, the upright plate 33 and the locking groove 35 cooperate to form a multi-dimensional limiting and fixing structure. In the horizontal direction, the upright plate 33 restricts the displacement of box 21 relative to box 11. When a collision occurs during transportation, the engaging surfaces of the upright plate 33 and the locking groove 35 can effectively disperse and offset the external force, preventing the upper turnover box from tipping over due to force imbalance, thus providing reliable safety for cargo transportation.

[0025] To further stabilize the position of the upright plate 33 and prevent it from loosening during transportation, components such as the support frame 41, slider 45, slide groove 42, top block 34, fastening groove 44, insert block 46, and slot 43 work together. The slider 45 is installed on the support frame 41 and can slide inside the slide groove 42. By pushing the support frame 41, the slider 45 is moved within the slide groove 42, adjusting the support frame 41 to a suitable lower position. At this time, the top block 34 is engaged inside the fastening groove 44, and the insert block 46 is inserted into the slot 43. Together, they fix the position of the support frame 41 and the upright plate 33. Because anti-slip particles are set between the insert block 46 and the slot 43, and between the top block 34 and the fastening groove 44, the friction of the contact surface is increased, effectively preventing the loosening and falling off of the components, and further enhancing the stability of the turnover box stacking structure.

[0026] When disassembling the turnover box, reverse the above process. First, pull the insert 46 out of the slot 43 to remove the lateral constraint of the support frame 41. Then, slide the support frame 41 upward to move the slider 45 in the slide groove 42, so that the top block 34 is disengaged from the fastening groove 44, thereby releasing the fixation of the support frame 41 and the upright plate 33. Then, fold the upright plate 33 up to easily separate the upper and lower turnover boxes. The whole operation process is simple and convenient, and can effectively ensure the stability and safety of the turnover box in transportation, storage and other links. Please see Figure 1 , Figure 2 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes: The protective component includes a horizontal rubber pad 51 and a vertical rubber pad 52. The horizontal rubber pad 51 is respectively embedded at both ends of the inner surface of the first box 11 and the second box 21, and the vertical rubber pad 52 is respectively embedded on both sides of the inner surface of the first box 11 and the second box 21. The horizontal rubber pad 51 and the vertical rubber pad 52 are respectively attached to the inner surfaces of box body 11 and box body 21, which can protect the goods when they are placed inside.

[0027] A support strip 54 is provided at one end of the outer surface of the horizontal rubber pad 51, and support grooves 53 are provided at both ends of the outer surface of the vertical rubber pad 52. The support bar 54 is snapped into the inside of the support groove 53; The horizontal rubber pad 51 and the vertical rubber pad 52 are installed and fixed by inserting the support into the support groove 53.

[0028] Working principle: When goods are placed inside the turnover box, the horizontal rubber pad 51 and the vertical rubber pad 52 are tightly attached to the inner surfaces of box body 11 and box body 21, respectively. Their good elasticity plays a key role. During the placement of goods, they come into contact with the horizontal rubber pad 51 and the vertical rubber pad 52 and are squeezed. The horizontal rubber pad 51 and the vertical rubber pad 52 deform under the force, converting the impact force applied by the goods into their own elastic potential energy, effectively buffering the external force on the goods, and avoiding direct collision between the goods and the hard surface of the box, thus providing all-round protection for the goods.

[0029] In terms of installing and fixing the horizontal rubber pad 51 and the vertical rubber pad 52, the support is inserted into the support groove 53, and the two fit together to form a stable connection structure. The support groove 53 plays a limiting role for the support, ensuring that the support maintains a stable position after installation. When the support is inserted into the support groove 53, the horizontal rubber pad 51 and the vertical rubber pad 52 are in close contact with the support. The support, with its own rigidity, provides stable support force for the rubber pads, and firmly fixes the horizontal rubber pad 51 and the vertical rubber pad 52 inside the box.
