[0039] See also Figure 1-Figure 4 A sliding door body 6 is provided between the first door frame 1 and the second door frame 14, and a plurality of mounting seats 10 are provided on the sliding door body 6. When the sliding door body 6 moves, it will drive the mounting seats 10 to move. A roller shaft 11 is provided on the outer surface of the mounting seat 10, and a roller 13 is provided at one end of the roller shaft 11. When the mounting seat 10 moves, it will drive the roller shaft 11 to move, and the roller 13 can rotate, which is convenient for guiding the sliding door body 6. A rubber member 12 is sleeved on the outer wall of the roller shaft 11. The setting of the rubber member 12 can protect the roller shaft 11. A torsion spring 8 is provided on the outer wall of the rotating shaft 3. The roller 13 is located inside the guide groove 15, and one side of the roller 13 contacts the inner wall of the guide groove 15 so that the roller 13 can roll inside the guide groove 15, thereby improving the stability of the movement of the sliding door body 6.

[0040] Specifically, the buffer assembly 9 includes a buffer spring 901 and a telescopic rod 902 arranged inside the guide groove 15 and a movable groove 904 opened above the inside of the guide groove 15, a trigger switch 905 is installed on one side of the inside of the movable groove 904, and a pressure block 906 is arranged inside the movable groove 904. When the pressure block 906 moves, it will squeeze the buffer spring 901 and the telescopic rod 902, so that the buffer spring 901 is compressed and the telescopic rod 902 is contracted. One end of the buffer spring 901 and the telescopic rod 902 are both installed with a slider 903, the slider 903 is connected to the pressure block 906, and the pressure block 906 is slidably connected to the movable groove 904. When the pressure block 906 moves, it will drive the slider 903 to move, so that the slider 903 can slide inside the movable groove 904.

[0041] Embodiment 2:

[0042] On the basis of the above-mentioned first embodiment, after the sliding door body 6 moves upward, it is necessary to limit the sliding door body 6 to prevent the sliding door body 6 from moving downward at will, so the following structure is provided to limit the sliding door body 6.

[0043] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A protective cover 18 is installed on the other side of the first door frame 1 and the second door frame 14, and an electric push rod 16 is installed inside the protective cover 18. The output end of the electric push rod 16 is installed with a limit plate 17 through a telescopic rod. After the limit plate 17 moves, it will move into the guide groove 15 and contact with the bottom of the sliding door body 6 to limit the sliding door body 6. The trigger switch 905 is electrically connected to the electric push rod 16 and the drive motor 7 respectively. When the trigger switch 905 is pressed, it will start the electric push rod 16 and turn off the drive motor 7. The operation of the electric push rod 16 can extend the telescopic rod and thereby drive the limit plate 17 to move.

[0044] The working principle of the utility model is as follows: first, when the sliding door body 6 needs to be moved up, the driving motor 7 can be started, and the driving motor 7 can drive the rotating shaft 3 to rotate, and the rotating shaft 3 drives the hexagonal supporting wheel 4 to rotate. Since the hexagonal supporting wheel 4 is engaged with the engaging groove 5 on the sliding door body 6, the sliding door body 6 is driven to rise, and the sliding door body 6 drives the roller shaft 11 to move, and drives the roller 13 to roll inside the guide groove 15. When the sliding door body 6 is opened to the limit position, the roller 13 will push the pressure block 906 to move. When the pressure block 906 moves, it will squeeze the buffer spring 901 and the telescopic rod 902, so that the buffer spring 901 is compressed and the telescopic rod 902 is contracted, thereby buffering the sliding door body 6 and preventing The sliding door body 6 continues to move and directly collides with the inner wall of the guide groove 15, and the pressure block 906 drives the slider 903 to move, and the slider 903 touches the trigger switch 905. The trigger switch 905 starts the electric push rod 16 and turns off the drive motor 7, so that the drive motor 7 no longer drives the rotating shaft 3 to rotate, and prevents the drive motor 7 from continuing to drive the rotating shaft 3 and the hexagonal support wheel 4 to rotate, so that the drive motor 7 can be turned off immediately when the sliding door body 6 is opened to the limit position, and the electric push rod 16 can extend the telescopic rod and drive the limit plate 17 to move. After the limit plate 17 moves, it will move into the inside of the guide groove 15 and contact with the bottom of the last roller 13, so as to limit the sliding door body 6 and prevent the sliding door body 6 from moving downward at will.
