When the protective door body 2 falls, the height value detected by the distance sensor 7 changes rapidly. At this time, the controller controls the electric push rod 13 to start, so that the lock block 28 is separated from the locking toothed plate 23. At this time, the reset force generated by the volute spring 18 can make the rotating rod 16 rotate, so that the second connecting rod 15 drives the locking toothed plate 14 to move horizontally, so that the locking toothed plate 14 squeezes the wall of the toothed rod 11, thereby instantly fixing the position of the locking box 8, thereby instantly fixing the falling of the protective door body 2, and preventing the occurrence of falling;

[0038] When manual unlocking is required, it is only necessary to turn the rotating knob 22 to control the rotation of the first bevel gear 19 through the second bevel gear 21, so that the spiral spring 18 generates elastic force and controls the locking tooth plate 14 to reset.

The rotation angle of the locking toothed disk 23 can be fixed, which is convenient for unlocking and improves the use effect.
