the door comprises a rear door panel 1, wherein a main shaft 4 is fixed on the rear door panel 1, and a sleeve 5 is sleeved on the main shaft 4;

the front door panel 2 is provided with a shaft hole, and the front door panel 2 is sleeved on the sleeve 5 through the shaft hole;

the limiting plate 3 is fixed with the sleeve 5;

the rear door panel 1 is provided with a sealing ring 8; the opposite end surfaces of the limiting plate 3 and the front door panel 2 are respectively provided with a limiting protrusion 21 and a limiting groove 31, the limiting protrusion 21 is in shape fit with each other, the height of the limiting protrusion 21 gradually decreases from the center to the two ends, and the depth of the limiting groove 31 gradually decreases from the center to the two ends.

The main shaft 4 of the hatch cover is fixedly connected with the rear door panel 1 relatively, and preferably, the main shaft 4 can be vertically fixed at the central position of the rear door panel 1. The sleeve 5 of the hatch cover is fixedly connected with the limiting plate 3, and preferably, the sleeve 5 can be vertically fixed at the central position of the limiting plate 3. Therefore, after the sleeve 5 is movably sleeved on the main shaft 4, the sleeve 5 and the main shaft 4 can rotate relatively, and the limiting plate 3 and the rear door panel 1 can form a relatively rotating assembly relation by means of the relative rotation between the sleeve 5 and the main shaft 4. Meanwhile, after the front door panel 2 is movably sleeved on the sleeve 5 through the shaft hole, the front door panel 2 can also rotate around the sleeve 5, and preferably, the shaft hole is also positioned in the center of the front door panel 2. Preferably, the front door panel 2, the rear door panel 1 and the limit plate 3 are all arranged in a circular structure.

In this structure, the opposite end surfaces of the limiting plate 3 and the front door panel 2 are also provided with a limiting protrusion 21 and a limiting groove 31 which are matched with each other, preferably, the limiting protrusion 21 is arranged on the end surface of the front door panel 2, and the limiting groove 31 is arranged on the end surface of the limiting plate 3. Wherein, spacing arch 21 highly reduces gradually to both ends direction from its center, and spacing recess 31 reduces gradually to both ends direction degree of depth from its center, relies on this kind of collocation structure of spacing arch 21 and spacing recess 31, when limiting plate 3 rotated for preceding door plant 2, can control holding of spacing arch 21 adaptation and advance in spacing recess 31, perhaps break away from in the spacing recess 31.
