The upper cover 2 and the lower cover 1 are connected to the side wall of the open-top container via multiple sets of flipping mechanisms 3. The open-top container in this embodiment can be a transport equipment with an open-top structure, such as a shipping container.

[0030] like Figure 2 As shown, the lower cover 1 is a frame structure composed of end beams 1-1, side longitudinal beams 1-2, central longitudinal beams 1-3, and a top plate 1-6. The frame also incorporates reinforcing structures such as reinforcing beams and stiffening ribs. End beams 1-1 and side longitudinal beams 1-2 are U-shaped structures, each with a sealing strip 1-7 inside. The bent edge of end beam 1-1 is higher on the outer side of the open-top box than on the inner side, forming a rain shield. The lower cover 1 frame forms a structure where the middle of the open-top box is higher than the sides, suitable for the tilt angle formed after loading bulk materials on top, increasing the loading volume. Tilting shafts and their reinforcing seats 1-5 are installed at both ends of the lower cover 1 frame, serving as the force points when the top cover is tilted. A rain shield bent plate 1-4 is installed near the middle of the open-top box in the lower cover 1 frame. Multiple sets of support plates 1-8 and support plates 1-9 are installed at the bottom of the central longitudinal beam 1-3. The support plates 1-8 support the upper cover 2 to share its weight, while the support plates 1-9 support the lower cover 1 to share its weight with the internal longitudinal beams. A rainproof edge 1-10 is installed around the inner perimeter of the open-top box's top beam. The rainproof edge 1-10, together with the end beam 1-1 and the side longitudinal beams 1-2, forms a labyrinth structure, simultaneously compressing the sealing strip 1-7 to form a rainproof and sealed structure. Figure 4 As shown.

[0031] like Figure 3 As shown, the upper cover 2 has a similar structure to the lower cover 1, employing a frame structure composed of end beams 1-1, side longitudinal beams 1-2, middle longitudinal beams 1-3, and top plate 1-6. Sealing strips 1-7 are installed inside both the end beams 1-1 and the side longitudinal beams 1-2. A cap-shaped plate 2-1 is installed near the center of the open-top box in the upper cover 2 frame. Sealing strips 1-7 are installed in the groove of the cap-shaped plate 2-1. The angle of the cap-shaped plate 2-1's burr is lower than the inclination angle of the lower cover 1, forming a labyrinth sealing structure. Figure 5 As shown. Rainproof baffles 2-2 are installed at both ends.

[0032] like Figure 6 As shown, the flipping mechanism 3 consists of a fixed ear seat 3-1, a flipping ear seat 3-2, and a flipping arm 3-3. The fixed ear seat 3-1 and the flipping ear seat 3-2 are connected to the flipping arm 3-3 by means of pins, bolts, etc. The fixed ear seat 3-1 is connected to the side wall, and the flipping ear seat 3-2 is connected to the lower cover 1 and the upper cover 2.

[0033] This utility model relates to a flip-top cover and its sealing structure for open-top containers. The flip-top mechanism allows the cover to be opened without encroaching on ground space. The labyrinth structure and sealing strips provide a rainproof seal. The flip-top cover is designed to be high in the middle and low on both sides, matching the angle formed by the top loading of particulate bulk materials, increasing the internal volume, and preventing rainwater accumulation.
