Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other. The embodiments of this application are described below with reference to Figures 1-6.According to an embodiment of this application, a logistics turnover box is provided, as shown in Figures 1, 2, 3, 4, and 5, including: a box body 1, a box cover 2, an edge drainage groove 3, and a waterproof flap 4. The box body 1 has an opening and a receiving cavity communicating with the opening; two box covers 2 are rotatably connected to the opening, and when both box covers 2 are simultaneously closed on the box body 1, they can close the receiving cavity, forming an assembly gap between the two box covers 2; the edge drainage groove 3 and the waterproof flap 4 are respectively provided on the edges of the two box covers 2 near the assembly gap; when the two box covers 2 are simultaneously closed on the box body 1, the edge drainage groove 3 is used to collect water falling on the box cover 2 and discharge it to the outside of the box cover 2, and the waterproof flap 4 is used to cover the assembly gap. 35 In the above embodiment, by setting an edge drainage groove 3 on the edge of the box cover 2 near the assembly gap to collect rainwater and other water stains, water falling on the box cover 2 near the assembly gap can be discharged to the outside of the box cover 2, preventing water from flowing into the assembly gap; while setting a waterproof flap 4 on the edge of the box cover 2 near the assembly gap to cover the assembly gap, rainwater and other water stains are prevented from falling directly into the assembly gap; thus, rainwater and other water stains can be prevented from flowing into the box body 1 of the logistics turnover box through the assembly gap, ensuring the waterproof performance of the logistics turnover box, so as to avoid the wet damage of the items shipped in the box. Specifically, the lid 2 is rotatably connected to the opening of the box body 1 via hinges and other structures. Having two lids 2 on the box body 1, designed to open in opposite directions, reduces the space occupied when the lids 2 are open, facilitating the loading and unloading of items inside the box. To ensure the normal opening and closing of the two lids 2, a gap is designed between them to allow for smooth relative movement. When rainwater or water leaking from upper cargo falls onto the lids 2 during logistics transportation, the edge drainage groove 3 near the edge of the gap catches the water flowing onto the gap and drains it outside the lids 2, preventing water from flowing directly into the box body 1. The waterproof flap 4 near the edge of the gap covers the gap, preventing water from falling directly into it, thus providing double waterproof protection for the gap area and effectively draining rainwater and other water stains from the edge of the lids 2 near the gap. Furthermore, this embodiment does not limit the specific arrangement of the edge drainage groove 3 and the waterproof gusset 4.In one implementation, when the edges of the two open-topped lids 2 are arranged in a straight line, the edge drainage groove 3 is arranged in a straight line through the edge of one lid 2, and the waterproof flap 4 is arranged in a straight line through the edge of the other lid 2. In another implementation, when the edges of the two open-topped lids 2 are arranged in a bent shape, the edge drainage groove 3 is arranged in a bent shape at the edge of the lid 2, and the waterproof flap 4 is arranged in a bent shape at the edge of the lid 2. The distribution of the edge drainage groove 3 and the waterproof flap 4 on the two lids 2 is not limited. For example, the edge drainage groove 3 can be completely arranged at the edge of one lid 2, and the waterproof flap 4 can be completely arranged at the edge of the other lid 2. Alternatively, the edge drainage groove 3 and the waterproof flap 4 can be divided into multiple segments and arranged intersectingly at the edges of the two lids 2. 20 Further, in this embodiment, the edge drainage groove 3 extends outward at the side edge of the lid 2, facilitating water drainage to the outside of the lid 2. In some embodiments, as shown in Figures 1, 2, 4, and 5, when both lids 2 are simultaneously closed on the box body 1, the edge of the waterproof flap 4 extends beyond the assembly gap to above the edge drainage groove 3, allowing water falling on the lid 2 to flow into the edge drainage groove 3 from the edge of the waterproof flap 4. 25 In the above embodiments, while ensuring that the waterproof flap 4 blocks the assembly gap and prevents water from falling directly into the assembly gap, the edge of the waterproof flap 4 extends beyond the assembly gap to above the edge drainage groove 3, allowing water falling on the lid 2 to flow into the edge drainage groove 3 from the edge of the waterproof flap 4, further improving the waterproof effect of the logistics turnover box. Specifically, in the preferred embodiment, when the edge of the waterproof panel 4 extends beyond the assembly gap to above the edge drainage groove 3, the edge of the waterproof panel 4 is positioned at the middle of the area above the edge drainage groove 3, to ensure that water at the edge of the waterproof panel 4 can accurately flow into the edge drainage groove 3.In some embodiments, as shown in Figures 1, 2, 4, and 5, the edge of the box cover 2 near the assembly gap is provided with protruding teeth 201 and concave teeth 202. The protruding teeth 201 are formed by at least a portion of the box cover 2 extending towards the assembly gap, and the concave teeth 202 are formed by at least a portion of the box cover 2 recessing away from the assembly gap. The protruding teeth 201 and concave teeth 202 on one box cover 2 are spaced apart from each other. When two box covers 2 are simultaneously closed on the box body 1, the protruding teeth 201 on one box cover 2 engages with the concave teeth 202 on the other box cover 2, and a splicing seam 203 communicating with the assembly gap is formed between two adjacent protruding teeth 201. At least a portion of the edge drainage groove 3 and / or the waterproof flap 4 are provided on the edge of the protruding teeth 201. When two box covers 2 are simultaneously closed on the box body 1, the waterproof flap 4 can cover the splicing seam 203 to cover the gap. The assembly gap is 5, and the edge of the waterproof cover plate 4 extends beyond the splice seam 203 to the top of the edge drainage groove 3. In the above embodiment, a protruding tooth 201 and a concave tooth 202 are provided between the two box covers 2 to facilitate the fastening between the two box covers 2 and improve the sealing performance of the logistics turnover box; at least a part of the edge drainage groove 3 and the waterproof cover plate 4 are provided at the edge of the protruding tooth 201, so that the waterproof cover plate 4 can cover the splice seam 203 to cover the assembly gap, preventing rainwater and other water stains from falling into the assembly gap through the splice seam 203, and the edge of the waterproof cover plate 4 extends beyond the splice seam 203 to the top of the edge drainage groove 3, so that water falling on the box cover 2 can flow from the edge of the waterproof cover plate 4 into the edge drainage groove 3 on the other side of the splice seam 203. Specifically, when the two lids 2 are simultaneously closed onto the box body 1, a straight assembly gap is formed because the edges of the two lids 2 near the receiving cavity are arranged in a straight line. By providing protruding teeth 201 formed by at least a portion of the lids 2 extending towards the assembly gap, and concave teeth 202 formed by at least a portion of the lids 2 recessing away from the assembly gap, the protruding teeth 201 will pass over the assembly gap while the two lids 2 are fastened together, thereby shielding the assembly gap and preventing rainwater and other water stains from falling directly into the assembly gap.Simultaneously, the interlocking protruding teeth 201 and concave teeth 202 form a splicing seam 203 between the two box covers 2 on the side away from the receiving cavity, communicating with the assembly gap. At this time, the edge drainage groove 3 and the waterproof plate 4 provided on the edge of the protruding teeth 201 interact to prevent rainwater and other water stains from falling into the assembly gap through the splicing seam 203, and allow water falling on the box cover 2 to flow from the edge of the waterproof plate 4 into the edge drainage groove 3 on the other side of the splicing seam 203. Further, the edge drainage groove 3 has a water-receiving portion provided on the edge of the protruding teeth 201 and a water-guiding portion communicating with it for drainage. At least part of the edge drainage groove 3 refers to the water-receiving portion of the edge drainage groove 3 provided on the edge of the protruding teeth 201. Further, this embodiment does not limit the specific distribution of the water-receiving portion of the edge drainage groove 3 provided on the edge of the protruding teeth 201 and the waterproof plate 4. In one embodiment, edge drainage grooves 3 are provided at all edges of the protrusions 201 of one cover 2, and waterproof flaps 4 are provided at all edges of the protrusions 201 of the other cover 2. In another embodiment, edge drainage grooves 3 and waterproof flaps 4 are provided at intervals at all edges of the protrusions 201 of one cover 2, and similarly, waterproof flaps 4 are provided at intervals at all edges of the protrusions 201 of the other cover 2. The waterproof flaps 4 at the edges of the water-receiving parts of the edge drainage grooves 3 are provided one-to-one, ensuring that the waterproof flaps 4 cover the splice seam 203 and that the edge of the waterproof flaps 4 extends beyond the splice seam 203 to above the edge drainage grooves 3. Further, the protrusions 201 and concave teeth 202 are fastened together by snaps and slots. In this embodiment, the outer surface of the concave teeth 202 is provided with snaps, and the inner side of the protrusions 201 is provided with slots. In some embodiments, as shown in Figures 1, 2, 4, and 5, the edge drainage channel 3 includes a water receiving channel 30130 and a water diversion channel 302. The water receiving channel 301 is located at the edge of the protruding tooth 201 and is used to collect water falling on the protruding tooth 201 and the waterproof cover plate 4; the water diversion channel 302 is connected to the water receiving channel 301 and is used to collect water from the water diversion channel 302 and discharge it to the outside of the tank cover 2. In the above embodiments, the water falling on the protruding tooth 201 and the waterproof cover plate 4 is collected by the water receiving channel 301, and the water flowing out of the water receiving channel 302 is collected by the water diversion channel 302 and finally discharged to the outside of the tank cover 2, thereby realizing the drainage operation of the edge drainage channel 335. Specifically, the water receiving channel 301 is distributed along the edge of the protruding tooth 201, and the water diversion channel 302 is distributed along the length direction of the tank cover 2.In some embodiments, as shown in Figures 1, 2, 4, and 5, a water inlet trough 302 is located downstream of the water receiving trough 301 and extends through the length of the cover 2. In the above embodiments, the water inlet trough 302 is located downstream of the water receiving trough 301 to receive water from the water inlet trough 302, and the water inlet trough 302 extends through the length of the cover 2 to discharge water outside the cover 2. Specifically, the end of the edge drainage trough 3 extending outward, that is, the end of the water inlet trough 302 extending outward, is located at the side edge of the cover 2 and has a notch to discharge water outside the cover 2. In some embodiments, as shown in Figures 1, 4, and 5, the water receiving trough 301 is located at the side edge of the protrusion 201, the water inlet trough 302 is located at the root of the protrusion 201, and multiple water receiving troughs 301 are connected. In the above embodiments, the water receiving trough 301 is located on the side edge of the protruding tooth 201 to facilitate cooperation with the waterproof cover plate 4 also located on the side edge of the protruding tooth 201; the water guiding trough 302 is located at the root of the protruding tooth 201, so that it is located close to the edge of the box cover 2 in the same position as the water receiving trough 301, thereby improving the compactness of the components of the edge drainage trough 3 and facilitating efficient drainage. Specifically, the protruding tooth 201 has a trapezoidal structure, the water receiving trough 301 is located at the edge of one side of the protruding tooth 201; the water guiding trough 302 is located at the edge of the bottom edge of the protruding tooth 201, and the protruding tooth 201 extends through the length of the box cover 2. In some embodiments, as shown in Figures 1 and 2, the logistics turnover box also includes a middle drainage trough 5, which is located on the panel of the box cover 2. The middle drainage trough 5 extends through the length of the box cover 2 and is used to collect water falling on the panel of the box cover 2 and discharge it to the outside of the box cover 2. In the above embodiments, a central drainage groove 5 extending through the length of the lid 2 is provided to drain water falling on the panel of the lid 2 to the outside of the lid 2, preventing water from flowing further toward the assembly gap. Specifically, the outwardly extending end of the central drainage groove 5 is located at the side edge of the lid 2 and has a notch to facilitate water drainage to the outside of the lid 2. In some embodiments, as shown in Figures 1 and 2, the panels of the lid 2 on both sides of the central drainage groove 5 are respectively constructed as downwardly inclined slopes. In the above embodiments, the panels of the lid 2 on both sides of the central drainage groove 5 are respectively constructed as downwardly inclined slopes to improve the drainage efficiency of the central drainage groove 5.Specifically, the panels of the box covers 2 located on both sides of the central drainage channel 5 are respectively constructed as downwardly inclined slopes 25, so that the panels of the box covers 2 on both sides of the central drainage channel 5 have a "V" shape structure, thereby making the central drainage channel 5 in a low position, so as to collect water on the panels of the box covers 2 into the central drainage channel 5. In some embodiments, as shown in Figures 2 and 6, the top of the box body 1 is provided with a first clearance portion 101 and a second clearance portion 102; the first clearance portion 101 is configured to conform to the outer contour of the edge drainage channel 3, and the outer wall of the edge drainage channel 3 can be fitted into the first clearance portion 101; the second clearance portion 102 is configured to conform to the outer contour 30 of the central drainage channel 5, and the outer wall of the central drainage channel 5 can be fitted into the second clearance portion 102.
