[0031] The working principle of this utility model is as follows: When it is necessary to install the floor door during actual construction, the fixed frame 3 can be installed on the floor slab through the installation component. Then, the construction hoist is operated. When the cage reaches the corresponding floor, the construction hoist sends a signal and controls the drive component 10 of the corresponding floor, so that the drive component 10 drives the locking plate 13 to retract and exit the slot 16. At the same time, the linkage plate 6 extends, and then the cage door of the cage opens. At the same time, the cage door lifts the linkage plate 6 through the door lifting plate, and the folding floor door component is opened through the linkage plate 6.
[0032] Furthermore, the drive assembly 10 includes a rotation drive member, a first drive wheel 15, and a second drive wheel 14. Both the first drive wheel 15 and the second drive wheel 14 are rotatably connected to the interior of the linkage top box 9.

[0041] As can be seen from the above description, it is advantageous for the first door 5 to slide inside the fixed frame 3 via the first slide groove 7, and for the second door 4 to slide inside the fixed frame 3 via the second slide groove 8. At the same time, the lower part of the second slide groove 8 is closed, so that the first door 5 and the second door 4 are staggered when closed. When the first door 5 slides upward, the second door 4 is lifted up by the linkage top box 9.
[0042] Furthermore, it also includes a buffer pad 12, which is laid on the upper part of the linkage top box 9.
