[0022] The prior art discloses a utility model patent with the application number CN202122932591.4 and the patent name of a sealing structure of an iron can. Its structure is to curl the bottom of the barrel and the edge of the barrel body along the roller groove curve and then flatten the curled part by a hydraulic press to achieve line sealing. However, such sealing has the following problems: the sealing effect decreases after deformation, and the processing process is complex and the cost is high.

[0023] To solve the above problems, this embodiment discloses a surface-sealed sealing structure of a tank body 101, and its structure is as Figure 1 shown. The sealing structure of the tank body 101 includes the tank body 101 and a tank bottom 102 connected to the bottom of the tank body 101. An arc-shaped first bending part 103, a flat first fitting part 106, and a flat second fitting part 107 are sequentially arranged along the inner side of the tank wall at the bottom of the tank body 101; the periphery of the tank bottom 102 is bent towards the direction close to the tank body 101 to form an L-shaped concave platform 105, and the outer side of the concave platform 105 extends and bends into an arc-shaped second bending part 104 away from the tank body 101; the first fitting part 106 and the second fitting part 107 are respectively in contact with the side surface of the concave platform 105 to form a surface seal, and the second bending part 104 is in contact with the first bending part 103 to form a fitting seal.

[0024] Specifically, for the surface-sealed sealing structure of the tank body 101 in this embodiment, each sealing surface is formed by the surface contact between the arc-shaped first bending part 103, the second bending part 104, and the flat first fitting part 106 and the second fitting part 107, effectively improving the sealing performance of the metal tank body 101, with a simple processing process and lower cost.

[0025] Furthermore, the first fitting part 106 and the second fitting part 107 are arranged perpendicularly and intersectingly, which can effectively improve the strength and stability of the tank body structure.

[0026] Furthermore, one end of the second fitting portion 107 away from the first fitting portion 106 abuts against the inner side of the second bending portion 104; one end of the second bending portion 104 away from the concave platform 105 abuts against the inner side of the first fitting portion 106. Through the above two abutting structures, two auxiliary support points and sealing points are formed, further enhancing the strength and sealing performance of the tank body structure in this embodiment.

[0027] Specifically, the tank body 101, the first bending portion 103, the first fitting portion 106, and the second fitting portion 107 are integrally formed, and the tank bottom 102 and the second bending portion 104 are integrally formed; in addition, the thicknesses of the tank body 101, the tank bottom 102, the first bending portion 103, the first fitting portion 106, the second fitting portion 107, and the second bending portion 104 are the same, which can ensure the consistency between the tank body 101 and the tank bottom 102 during processing and improve the yield rate of the tank body structure processing in this embodiment.
