As the cover plate 2 is further pressed down, the sealing gasket 20 (fixedly connected to the inner wall of the annular positioning groove 18) will come into close contact with the outer side of the annular positioning plate 19, forming the first layer of seal. This layer of seal effectively prevents external dust, moisture and other impurities from entering the barrel 1. As the cover plate 2 continues to be pressed down, the inner ring plate 15 (fixedly connected to the inner side of the bottom of the cover plate 2) will pass through the opening of the barrel 1 and enter the barrel 1. At the same time, the annular sealing strip 16 (fixedly connected to the top and bottom positions of the outer wall of the inner ring plate 15) will come into close contact with the annular sealing strip 17 (fixedly connected to the top of the inner barrel 1), forming the second layer of seal. This layer of seal ensures that the barrel 1 To ensure the sealing of the internal materials and prevent leakage, as the cover plate 2 is fully in place, the annular retaining plate 13 (fixed to the outer bottom of the cover plate 2) will naturally align and insert into the annular retaining groove 12 (located on the outer top of the barrel 1). At this time, the limiting block 14 (fixed to the bottom of the annular retaining groove 12) will lock the bottom of the annular retaining plate 13 to prevent the cover plate 2 from accidentally falling off or loosening. On the outside of the cover plate 2, the outer fixing ring plate 6 will pass through the L-shaped annular bottom plate 8 (fixed to the top of the outer side of the barrel 1) and make close contact with the sealing gasket 9 inside the L-shaped annular bottom plate 8 to form a third layer of seal. This layer of seal further enhances the sealing performance of the barrel 1. At the same time, the arc-shaped buckle block 11 (fixed to the inner wall of the outer fixing ring plate 6) will naturally align and insert into the buckle groove 10 (located on the outer surface of the barrel 1 above the L-shaped annular bottom plate 8) to achieve additional fixing. This step ensures the stability of the cover plate 2 during transportation or storage.

[0022] In summary, this plastic drum for storing industrial raw materials, through its multi-layered sealing structure, including the cooperation between the annular positioning groove 18 and the annular positioning plate 19, the addition of a second sealing gasket 20, and the tight contact between the inner ring plate 15 and the first and second annular sealing strips 16 and 17, greatly improves the sealing performance between the top cover and the drum body 1. This multi-layered design effectively prevents gap expansion and leakage caused by factors such as vibration and temperature changes, ensuring the safety and stability of raw materials during long-term storage or transportation. Furthermore, the annular groove 12 on the outer side of the top of the drum body 1 engages with the annular locking plate 13 at the bottom of the cover plate 2. Meanwhile, a limiting block 14 is set for further fixation, making the connection between the top cover and the barrel 1 more stable. This design not only improves the overall structural strength of the plastic barrel, but also enhances its durability in various environments and reduces the risk of damage caused by external forces. The top cover design is simple and clear, and the installation and disassembly process is simple and quick. In particular, through the interlocking of the annular card plate 13 and the annular card groove 12, and the interlocking of the arc-shaped buckle block 11 and the buckle groove 10, the top cover can be quickly and firmly fixed to the barrel 1, and it is also easy to disassemble quickly when needed. This design not only improves work efficiency, but also reduces the difficulty of operation and cost.
