The horizontal portion is lower than the step portion and extends along the lateral direction. The floor overlaps the inner end of the horizontal part and extends along the transverse direction. The floor is higher than the horizontal part and together with the horizontal part and the step part, they form a water-retaining groove. An opening is formed at the upper end of the water-retaining groove. The connecting plate is placed over the opening, and the inner and outer ends of the connecting plate are fixedly connected to the floor and the step, respectively.

[0005] Furthermore, the outer end of the connecting plate is bent downward to form a lower extension plate, which is welded to the step portion.

[0006] Furthermore, the inner end of the connecting plate is inclined upward relative to the outer end, and the lower extension plate is located inside the water-blocking groove and welded to the inner end face of the step portion.

[0007] Furthermore, the upper end of the outer end face of the stepped portion is inclined inward relative to the lower end, the upper end of the lower extension plate is inclined inward relative to the lower end and its inclination angle is the same as that of the outer end face of the stepped portion, and the lower extension plate is welded to the outer end face of the stepped portion.

[0008] Furthermore, the inner end of the connecting plate is bent and extended to form an upper extension plate, which is welded to the top surface of the floor.

[0009] Furthermore, a sealing plate is fixedly covered on the outer end face of the floor. The sealing plate is located inside the water-blocking groove and is lower than or flush with the top surface of the floor. The inner end of the connecting plate is welded to the upper end of the sealing plate.

[0010] Furthermore, the floor is a T-shaped floor with its top surface higher than the top surface of the step portion.

The refrigerated container door end structure includes a threshold assembly 1, a floor 2, and a connecting plate 3.

[0017] like Figure 1 , Figure 2 As shown, the threshold assembly 1 includes an outer threshold 11 and an inner threshold 12 located inside the outer threshold 11. A base plate 13 is welded to the inner side of the lower end of the outer threshold 11. The inner threshold 12 is located above the base plate 13. The top surface of the inner threshold 12 protrudes upward to form a step 121. The upper end of the outer end face of the step 121 is inclined inward relative to the lower end so that the forklift can pass smoothly. The step 121 extends along the lateral direction X of the refrigerated container and its inner end face extends inward to form a horizontal part 122. The horizontal part 122 is lower than the step 121 and extends along the lateral direction X. The horizontal part 122 is plate-shaped and its bottom surface protrudes downward to form a hook 1221. The hook 1221 is used to hook the insulation layer (not shown) formed by the foam material. A PE block 14 is also provided between the horizontal part 122 and the base plate 13. The PE block 14 abuts against the horizontal part 122 and the base plate 13.

[0018] like Figure 1 , Figure 2 As shown, specifically, a groove 123 is formed between the inner sill 12 and the outer sill 11. An insert 124 is embedded in the groove 123. The top surface of the insert 124 is close to the top surfaces of the inner sill 12 and the outer sill 11 relative to the bottom surface to ensure that the top surface of the sill is flat. The step portion 121 is located inside the insert 124 and is higher than the insert 124 to prevent condensate from flowing back into the insert 124. In this embodiment, the inner end of the outer end of the inner sill 12 is hollow to form the groove 123. The top of the groove 123 is open. The upper end of the outer sill 11 is integrally bent inward to form a flat plate 111. The flat plate 111 is located above the groove 123 and has a gap between it and the inner sidewall of the groove 123 near the opening of the groove 123. The insert 124 is inserted into the groove 123 from the opening of the groove 123 and abuts against the inner bottom wall of the groove 123 and the flat plate 111. The insert 124 is made of PVC.

[0019] like Figure 1 , Figure 2 As shown, the floor 2 overlaps the inner end of the horizontal part 122 and extends in the transverse direction X. The floor 2 is higher than the horizontal part 122 and together with the horizontal part 122 and the step part 121, forms a water-blocking groove 4 for blocking condensate. An opening 41 is formed at the upper end of the water-blocking groove 4. The floor 2 is a T-shaped floor and its top surface is higher than the top surface of the step part 121. A sealing plate 21 for sealing the outer end of the floor 2 is fixedly covered on the outer end of the floor 2. The sealing plate 21 is located in the water-blocking groove 4 and is lower than or flush with the top surface of the floor 2 to prevent the floor 2 from becoming uneven due to its protrusion from the top surface of the floor 2. The sealing plate 21 is made of horseshoe aluminum. The upper end of the sealing plate 21 is inclined inward relative to the lower end and welded to the floor 2. The lower end of the sealing plate 21 is welded to the horizontal part 122.

[0020] like Figure 1 , Figure 2 As shown, the connecting plate 3 is installed on the opening 41. It is made of aluminum profile, and the inner and outer ends of the connecting plate 3 are fixedly connected to the floor 2 and the step 121, respectively. This can prevent the forklift from impacting the step 121 and the end of the floor 2 when entering or leaving the container, thus avoiding damage to the step 121 and the end of the floor 2 due to the impact of the forklift. This protects the threshold and the floor 2, reduces maintenance costs, and allows the forklift to enter and leave the container smoothly, further improving the safety of the operation.

[0021] like Figure 2 , Figure 3 As shown, the connecting plate 3 gradually rises from its outer end to its inner end. Specifically, the inner end of the connecting plate 3 is inclined upward relative to its outer end. To simplify the structure, facilitate installation, and enhance structural strength, the inner and outer ends of the connecting plate 3 are bent and extended to form an upper extension plate 32 and a lower extension plate 31, respectively. The upper extension plate 32 and the lower extension plate 31 are both located on the same side of the connecting plate 3 and are welded to the floor 2 and the step portion 121, respectively. Specifically, the inner end of the connecting plate 3 is bent and extended inward to form an upper extension plate 32, which is welded to the top surface of the floor 2. The outer end of the connecting plate 3 is bent and extended downward to form a lower extension plate 31, which is welded to the step portion 121. In this embodiment, the lower extension plate 31 is located inside the water-retaining groove 4 and welded to the inner end face of the step portion 121. Alternatively, in another embodiment, the upper end of the lower extension plate 31 is inclined inward relative to the lower end, and its inclination angle is the same as that of the outer end face of the step portion 121. The lower extension plate 31 is welded to the outer end face of the step portion 121, and the inner end of the connecting plate 3 is welded to the upper end of the sealing plate 21 (e.g., ...). Figure 3 As shown). Figure 4As shown, in other embodiments, the connecting plate 3 can be a split type, that is, there are multiple connecting plates 3, and the multiple connecting plates 3 are evenly distributed along the lateral direction X. When only two connecting plates 3 are provided, the distance between the two connecting plates 3 is adapted to the wheel track of the forklift so that the forklift can pass smoothly. The specific setting can be set according to actual needs.

[0022] This utility model's refrigerated container door end structure, by incorporating a connecting plate that covers the opening of the water-retaining groove, and whose inner and outer ends are fixedly connected to the floor and steps respectively, prevents forklifts from impacting the steps and floor ends when entering or exiting the container.
