The fixing component includes a fixing ring and a first protrusion. The cross-section of the fixing ring is L-shaped. The first protrusion is located at the bottom of the fixing ring. There are multiple first protrusions, which are arranged in a circumferential array. The first protrusion is integrally formed with the fixing ring. A receiving cavity is provided between the fixing component and the sealing cavity. An inflation ring is provided in the receiving cavity. A first concave thread is provided on one side of the sealing cavity. A second protrusion is provided on the barrel lid. A first convex thread is provided on the second protrusion. The first convex thread is used to connect with the first concave thread. A third protrusion is provided at the bottom of the second protrusion. The third protrusion is used to squeeze the inflation ring after being inserted into the receiving cavity.

[0006] The present invention is further configured such that: the opening of the barrel body is provided with a second convex thread, and the barrel cover is provided with a second concave thread; the second convex thread is used for threaded connection with the second concave thread, and the first convex thread and the second convex thread have the same structure.

[0007] The present invention is further configured such that: three reinforcing rings are provided on the outer wall of the barrel, the three reinforcing rings being located at the top, middle and bottom of the barrel respectively, and the reinforcing rings are made of aluminum alloy.

[0008] The present invention is further configured such that: the outer wall of the bucket lid is provided with multiple anti-slip ridges, the multiple anti-slip ridges are evenly distributed, and the anti-slip ridges are made of rubber material.

[0009] The present invention is further configured such that the thickness of the bucket lid is 3-5cm.

[0010] The present invention is further configured such that the outer side of the barrel is coated with a corrosion-resistant coating.

[0011] In summary, this utility model has the following beneficial effects: the multiple threaded connections and the inflatable ring greatly improve the sealing between the barrel and the lid, effectively preventing liquid or gas leakage, ensuring the quality and safety of the contents, and reducing the risk of material loss and environmental pollution. The three reinforcing rings on the outer wall of the barrel, located at the top, middle, and bottom respectively, significantly enhance the structural strength of the barrel, making it less prone to deformation during handling and storage, and extending the service life of the open barrel. The corrosion-resistant coating on the outside of the barrel effectively protects it from external corrosive substances, further extending the service life of the open barrel and reducing maintenance costs.

A sealing cavity 3 is formed at the top of the barrel body 1, and a fixing component 4 is installed within the sealing cavity 3. The fixing component 4 includes a fixing ring 5 and a first protrusion 6. The fixing ring 5 has an "L"-shaped cross-section. The first protrusion 6 is located at the bottom of the fixing ring 5 and is arranged in a circumferential array. The first protrusion 6 and the fixing ring 5 are integrally formed, making the structure more robust and enhancing the structural stability of the fixing ring 5, allowing it to better withstand pressure. A receiving cavity 7 is provided between the fixing component 4 and the sealing cavity 3, and an inflation ring 8 is installed within the receiving cavity 7. The pores of the inflation ring 8 are melt-treated, and the inflation ring 8 is completely sealed. The inflation ring 8 is made of silicone rubber, which has high chemical stability and corrosion resistance. It is strong and has good flexibility and elasticity. After inflation, it can maintain a good shape and performance. One side of the sealing cavity 3 is provided with a first concave thread 9, and the lid 2 is provided with a second protrusion 10. The second protrusion 10 is provided with a first protruding thread 11. The two are threaded together. This connection method makes the lid 2 and the body 1 fit tightly, effectively preventing external impurities from entering the bucket and ensuring the quality and safety of the contents. The bottom of the second protrusion 10 is provided with a third protrusion 12. The third protrusion 12 is used to insert into the receiving cavity 7 to squeeze one end of the inflation ring 8, causing the other end of the inflation ring 8 to expand and fit tightly with the second protrusion 10.
