The guide plate 150 is installed at the top of the first door body 100, bears the first guide wheel 160 and the second guide wheel 170, and is in contact with the third guide wheel 180 through the guide groove 220 designed on the inner side thereof, thereby achieving the function of synchronously driving the second door body 110 when the first door body 100 moves. In order to improve the use convenience and safety, the handle 140 is arranged on the inner side and the outer side of the first door body 100, so that the user can conveniently operate the door body from any side.

[0052] When it is necessary to open or close the linkage door, the user can start the sliding action of the first door body 100 by pulling the handle 140 on either side. As the first door body 100 moves along the first guide rail 200, it indirectly pushes the second door body 110 to move synchronously along the second guide rail 210 through the guide plate 150. In this process, the limiting blocks and limiting grooves at the bottom of each door body cooperate with each other to ensure the precise alignment and smooth running between the door bodies. Finally, all the movable door bodies will be compactly stored together, next to one side of the third door body 120, realizing efficient space utilization.
