The fourth protrusion 243 is connected to the supporting portion 242 and inserted into the embedded groove. Based on this, the present embodiment can achieve a high degree of sealing between the first door panel 120 and the second door panel 220 through the first sealing member 130, the second sealing member 140, and the third sealing member 230. At the same time, a high degree of sealing between the first door frame 110 and the second door frame 210 can be achieved through the assembly frame 300 and the fourth sealing member 240. This allows the present application to have both a lifting function and a stopping sealing effect without affecting the lifting function, and ensures that the operating environment is always stable.
