[0002] At present, in many medical and office occasions, in order to expand the access space as much as possible, the hidden sliding door structure is often used, that is, the door is moved into the wall when the door is opened, so that the door cannot be seen and the door does not affect the passage. This requires that the width of the hidden door cavity on the wall must be the same as the width of the door. In general, the width of the door required in this way is relatively large, mostly more than 2 meters, which requires the width of the wall to be more than 2 meters. In some occasions, the width of the door will be greater than the width of the solid wall. In this case, the hidden door cannot be installed, affecting the application of the hidden sliding door.

When the door needs to be closed, the inner door or the outer door is pulled hard to make the locking pin 8 break away from the constraint of the elastic door lock piece 7. The inner and outer doors slide leftward using the inclined surface under the action of gravity ( Figure 1 (in the figure, it is tilted to the lower left) If the inner door moves faster, the guide rope 13 will pull the outer door 2 to move, and the buffer spring 15 can slow down the moving speed until the inner door moves into place. Under the restriction of the pull rope, the outer door also moves into place. When the door needs to be closed, push either the inner door or the outer door to the left by hand, and the inner and outer doors will move synchronously through the position rope until the outer door is in place, and the locking pin 8 on the inner door is stuck in the elastic lock door piece 7 to realize the positioning of the inner and outer doors.
