[0002] "Door" refers to the entrance and exit of a building or a device installed at the entrance and exit that can be opened and closed. Traditional interior doors usually use the door frame as the fulcrum, the door leaf as the radius, and the dumpling chain as the center to solve the switching function in a fan-shaped manner. This switching method takes up a large space and is suitable for large apartments. Small apartments have less space, and this door body is difficult to set up and has a switching function. This switching method takes up a large space and is suitable for large apartments. Small apartments have less space, and this door body is difficult to set up and is very inconvenient to use.

[0003] When the existing folding door is in use, when the door is opened, one end of the door is connected to the frame and the other end is suspended. After a long time of use, the suspended end of the door will drop, causing the door frame to deform, thereby reducing the service life of the door and increasing the noise when closing the door.
