[0030] In summary, when the sliding door 4 is opened, the two supporting wheels 4.2 on the top of the door panel 4.1 are both located in the column cavity 1.3, and at this time, the rear wall of the door panel 4.1 does not rest against the front wall of the frame-shaped baffle 3.

[0031] When the sliding door 4 is closed, the supporting wheel 4.2 gradually transitions into the column cavity 1.1, and the slider 4.2 also slides from the slide groove 1.4 into the slide groove 1.2; at this time, the edge of the rear wall of the door panel 4.1 is in contact with the front wall of the frame baffle 3, and the rubber sealing strip 3.1 is stuck in the strip groove 4.1.3. The side wall of the door panel 4.1 away from the strip groove 4.1.3 is pressed against the inner side wall of the side beam 2, and then the rod body 4.3.3 is pressed, so that the polygonal plate 4.3.4 compresses the spring 4.3.6 and disengages from the polygonal groove 4.3.1.2. At this time, the rod body 4.3.3 can be rotated clockwise by the handle 4.3.2, and the rod body 4.3.3 rotates the swing rod 4.4.3 through the prism 4.3.5, so that the sealing column 4.4 moves outward and upward at the same time, and the outer side of the sealing column 4.4 is inserted into the strip groove 2.1, and the outer top of the sealing column 4.4 is inserted into the slot 1.5. At this time, the pressing of the rod body 4.3.3 is released, and the rebound force of the spring 4.3.6 pushes the polygonal plate 4.3.4 into the polygonal groove 4.3.1.2 again to achieve the positioning of the rod body 4.3.3, so as to ensure the sealing effect between the door panel 4.1 and the side beam 2.

[0032] The polygons corresponding to the polygonal plate 4.3.4 and the polygonal groove 4.3.1.2 are regular polygons. When the rod body 4.3.3 rotates one or more inner angles of the regular polygon, the sealing column 4.4 just completes the action of the outer side being inserted into the bar groove 2.1 and the outer top end being inserted into the slot 1.5; and when the rod body 4.3.3 is released, the polygonal plate 4.3.4 can just be re-inserted into the polygonal groove 4.3.1.2.
