For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The pallet box is often used for loading and packaging of goods in the logistics industry, which facilitates the handling and loading of goods. Using pallet box to load goods can reduce the number of goods handling, improve the efficiency of goods handling and loading, especially for small volume or irregular shape of goods. By using pallet box, the goods can also be protected to a certain extent, greatly reducing the damage.

[0046] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8The application provides a tray box, which comprises a bottom frame 100, wherein the bottom frame 100 comprises a supporting frame body 1, a bearing plate 2 and a liquid collecting groove 3; the supporting frame body 1 is in the shape of a cuboid frame for facilitating carrying and stacking. Of course, the supporting frame body 1 can also be provided in other shapes, which are not limited herein. The bearing plate 2 is arranged in the supporting frame body 1, and the edge of the bearing plate 2 is tightly connected with the supporting frame body 1 to seal the bottom of the bottom frame 100, so that when the goods in the tray box leak, the liquid cannot directly flow from the bottom of the bottom frame 100 to the external environment. At least one liquid collecting groove 3 is arranged in the bottom frame 100, and the liquid collecting groove 3 is arranged at the bottom of the bearing plate 2. At least one liquid collecting hole 21 is arranged on the bearing plate 2, and the liquid collecting hole 21 is communicated with the liquid collecting groove 3, so that the liquid on the bearing plate 2 can be collected in the liquid collecting groove 3 through the liquid collecting hole 21. The two ends of the liquid collecting groove 3 are tightly connected with the supporting frame body 1, so as to ensure that the liquid collected in the liquid collecting groove 3 cannot overflow from the two ends of the liquid collecting groove 3. In order to discharge the liquid in the liquid collecting groove 3 for centralized treatment or recycling, a liquid discharging hole 31 is arranged on the liquid collecting groove 3, and the liquid discharging hole 31 can be opened to discharge the liquid in the liquid collecting groove 3 or sealed to ensure the sealing of the liquid collecting groove 3. That is, when the tray box is loaded with goods, the liquid discharging hole 31 is in a sealed state, so that the leaked liquid can be collected in the liquid collecting groove 3 without leakage; when the tray box is in an idle state or the liquid in the liquid collecting groove 3 has been collected to a certain amount, the liquid discharging hole 31 can be opened, so that the liquid in the liquid collecting groove 3 flows out of the liquid discharging hole 31 for unified recycling and treatment.

[0047] The tray box provided by the embodiment supports the goods through the bearing plate 2 and seals the bottom of the bottom frame 100, so that when the goods leak, the liquid is collected in the liquid collecting groove 3 through the liquid collecting hole 21, avoiding the leakage of the liquid, especially the oil, which can pollute the external environment if directly discharged from the bottom of the tray box to the external environment. The collected oil can be recycled, avoiding the waste of resources.

[0048] Further, as shown in Figure 9 the bearing plate 2 is in the shape of a corrugated plate, the wave crest of the corrugated plate forms a bearing part 22, and the wave trough of the corrugated plate forms a liquid collecting part 23, that is, the bearing part 22 and the liquid collecting part 23 are arranged alternately; the bearing part 22 and the liquid collecting part 23 are arranged along the extension direction of the liquid collecting groove 3 respectively, and the liquid collecting hole 21 is arranged on the liquid collecting part 23; in this way, each liquid collecting part 23 intersects with the liquid collecting groove 3, and the bearing part 22 is located at the position of the wave crest of the corrugated plate and is used for bearing the goods in the tray box, improving the uniformity of the pressure of the goods on the bearing plate 2; also, the liquid leaked from the goods can quickly flow to the position of the wave trough, that is, the liquid collecting part 23, and then flows to the liquid collecting groove 3 through the liquid collecting hole 21, shortening the flow path and residence time of the leaked liquid in the bearing plate 2, so that the leaked liquid and the goods can be quickly separated, preventing the leaked liquid from continuously soaking at the bottom of the goods and polluting the goods.

[0049] Further, as shown in Figure 4 to Figure 6 Further, at least one side of the bearing plate 2 is provided with a liquid collecting groove 3, a first side wall 32 of the liquid collecting groove 3 is arranged between the bearing plate 2 and the support frame 1, and the first side wall 32 of the liquid collecting groove 3 abuts against the bearing plate 2 and the support frame 1 respectively, the connection between the bearing plate 2 and the first side wall 32 of the liquid collecting groove 3 is located above the liquid collecting groove 3, and corresponds to the opening 36 of the liquid collecting groove 3. Even if liquid leaks from both sides of the bearing plate 2 in the extension direction, the liquid can only flow into the liquid collecting groove 3, further improving the sealing performance of the bottom of the bottom frame 100. Further, the height of the first side wall 32 of the liquid collecting groove 3 is higher than the height of the bearing part 22 of the bearing plate 2. If the liquid flows along the bearing part 22 to the side, the first side wall 32 of the liquid collecting groove 3 blocks the liquid, preventing the liquid from overflowing from the edge of the bearing part 22. The height difference between the first side wall 32 of the liquid collecting groove 3 and the bearing part 22 of the bearing plate 2 can be set according to the specific application scene. As long as the first side wall 32 of the liquid collecting groove 3 can effectively prevent liquid from overflowing, and does not affect the loading and unloading of goods.

[0050] As shown in Figure 8 In the present embodiment, the liquid collecting groove 3 further includes a second side wall 33, a bottom wall 34 and a top wall 35. The second side wall 33 of the liquid collecting groove 3 is parallel to the first side wall 32 and is arranged in a spaced manner with the first side wall 32. The height of the second side wall 33 is lower than that of the first side wall 32. The bottom wall 34 is connected to the bottom of the first side wall 32 and the second side wall 33 respectively. The top wall 35 is connected to the top of the second side wall 33. An opening 36 is formed between the top wall 35 and the first side wall 32. The opening 36 is arranged corresponding to the position of the liquid collecting hole 21, so that the liquid flowing out of the bearing plate 2 can flow directly into the liquid collecting groove 3 through the liquid collecting hole 21 and the opening 36. The space for storing liquid in the liquid collecting groove 3 is formed between the first side wall 32, the second side wall 33, the bottom wall 34 and the top wall 35. The top wall 35 abuts against the bottom of the liquid collecting part 23, not only having a certain supporting effect on the bearing plate 2, but also reducing the area of the opening 36, which can block the liquid in the liquid collecting groove 3 to a certain extent, reducing the possibility of liquid overflowing in the liquid collecting groove 3.

[0051] As shown in Figure 4 and Figure 7As shown, as a preferred embodiment, liquid collecting troughs 3 are provided on both ends of the liquid collecting portion 23 along the length of the carrier plate 2, and each liquid collecting portion 23 is provided with a liquid collecting hole 21 connected to the liquid collecting trough 3; that is, the liquid collecting troughs 3 are provided on both sides of the carrier plate 2 along the extension direction, and each liquid collecting portion 23 is provided with a liquid collecting hole 21 at both ends. The liquid in the tray box flows into the liquid collecting portion 23, and then flows from both ends of the liquid collecting portion 23 into the liquid collecting trough 3. The liquid collecting holes 21 provided on both sides of the liquid collecting portion 23 facilitates the complete discharge of the liquid in the liquid collecting portion 23 into the liquid collecting trough 3. For example, by raising or lowering one side of the tray box along the length of the liquid collecting portion 23, thereby tilting the tray box, the liquid in the liquid collecting portion 23 will flow to the lower end, and then flow into the liquid collecting trough 3 through the liquid collecting holes 21 at that end.

[0052] like Figure 4 and Figure 9 As shown, the first end of the carrier plate 2 is bent upward to form a first connecting portion 24, and the second end of the carrier plate 2 is bent upward to form a second connecting portion 25.
