Upper part 11 is square cavity 111 for installation, and lower part 12 is U-shaped frame body with limiting groove 121 formed on the inner side. Further, the mute sliding door further includes moving door body 2, suspension moving assembly 3, liftable mute sliding rail 4 and drive lifting mechanism 5. Among them, the liftable mute sliding rail 4 is arranged in square cavity 111 through drive lifting mechanism 5, and moving door body 2 is hoisted and connected to liftable mute sliding rail 4 through suspension moving assembly 3. Therefore, the moving door body 2 can be moved along liftable mute sliding rail 4 to realize opening and closing door by pushing, and the height of liftable mute sliding rail 4 can be adjusted through drive lifting mechanism 5, so that the distance between the bottom surface of moving door body 2 and limiting groove 121 is changed, which can prevent friction noise and noise generated by compressing air when moving moving door body 2 at the same time.

[0025] Further, as Figure 1 ,Figure 2 、 Figure 3 and Figure 5 As shown in the drawings, the liftable mute sliding rail 4 comprises a sliding bearing part 41 and a connecting part 42, the sliding bearing part 41 is an open downward open square tube, and the connecting part 42 is connected with the driving lifting mechanism 5. Further, the driving lifting mechanism 5 comprises a guide rod 51, a guide hole column 52 and a flange gear 53. More specifically, the guide hole column 52 corresponding to the guide rod 51 is formed on the mounting horizontal plate 112, and the guide rod 51 is slidingly inserted into the guide hole column 52. The top of the guide hole column 52 is provided with an exhaust hole 521 for balancing air pressure. Two of the guide rods 51 are threadedly connected to the flange gear 53, and the flange gear 53 is engaged with a worm 54 for transmission. Rotating the worm 54 can drive the guide rod 51 to lift through the flange gear 53, so as to realize the lifting of the liftable mute sliding rail 4. One end of the worm 54 extends out of the square cavity 111, and the end face is provided with a countersunk regular hexagonal hole 541, so as to facilitate the adjustment by using a tool. As shown in Figure 2 , the embodiment can adopt an internal hexagonal wrench to rotate the worm 54 for adjustment.
