A guide plate 5 is fixedly connected to one end of the contact plate 2 extending into the elevator landing door 1. A flip wheel 6 is respectively arranged on the upper end of the guide plate 5. An assist push plate 3 is slidably arranged inside the elevator landing door 1, and the assist push plate 3 is located at one end of the guide plate 5. The assist push plate 3 and... The guide slide plate 5 is provided with a locking groove 9, and the flip wheel 6 is equipped with two locking protrusions 16. The locking protrusions 16 are respectively locked in the locking grooves 9 on the power push plate 3 and the guide slide plate 5. The bottom of the power push plate 3 is provided with a spring support plate 13, which is installed on the side wall of the elevator door 1. The spring support plate 13 and the power push plate 3 are connected by a compression spring 11. A micro switch 14 is installed on the side of the elevator door 1 near the power push plate 3. A control rod 15 is installed on the top of the power push plate 3, and the control rod 15 is in contact with the control end of the micro switch 14.

[0025] As one embodiment of this utility model, a guide rail 8 is installed on one side of the elevator landing door 1, and a guide slide plate 5 is slidably connected to the surface of the guide rail 8. The guide rail 8 is horizontally set.

[0026] In one embodiment of this utility model, the power push plate 3 and the guide slide plate 5 are arranged perpendicularly to each other. The power push plate 3 is slidably disposed inside the elevator landing door 1 through the sliding sleeve plate 4, and the sliding sleeve plate 4 is installed on the surface of the elevator landing door 1.

[0027] As one embodiment of this utility model, the bottom of the push plate 3 is provided with a guide rod groove 10, and a guide rod 12 is vertically connected to the surface of the spring support plate 13. One end of the guide rod 12 is movably inserted into the guide rod groove 10, and the compression spring 11 is movably wound around the surface of the guide rod 12.

[0028] In one embodiment of this utility model, the micro switch 14 is disposed on the top of the push plate 3.

[0031] Specific working principle:

[0032] During normal elevator operation, if the touch plate 2 is triggered, the staggered touch plate 2, positioned along the side wall of the elevator landing door 1, allows for the detection of personnel information from multiple locations and enables contact at multiple heights. The touch plate 2 presses against the guide slide plate 5, which in turn pushes the locking protrusion 16 at one end of the tilting wheel 6 to rotate. This, in turn, causes the other locking protrusion 16 to push the assist push plate 3 upward, bringing the control lever 15 closer to the micro switch 14 and triggering it. This controls the operation of the elevator landing door 1, stopping its continued operation. The state of the micro switch 14 can be adjusted via the control lever 15, thereby triggering the automatic recovery function of the elevator landing door 1 and preventing dragging. The staggered touch plate 2 not only increases the range of contact between the two elevator landing doors 1 but also prevents the touch plates 2 from contacting each other and triggering the switch.

[0033] In its natural state, the compression spring 11 at the bottom pulls the push plate 3 downward, thereby moving the control rod 15 away from the micro switch 14 and no longer controlling the micro switch 14, allowing the elevator door 1 to continue operating normally.
