Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Examples. The magnetic attraction type construction elevator electric door is shown in figures 1 to 5, and comprises a door frame 1, wherein a left door plate 2 and a right door plate 3 which are oppositely opened are rotatably connected to the door frame 1, and 2 electric driving mechanisms 4 which respectively drive the left door plate 2 and the right door plate 3 to open and close are connected to the door frame 1; the top of the right door plate 3 is connected with a suction plate 5, an electromagnetic door stopper 6 is arranged at the position of the top of the door frame 1 corresponding to the suction plate 5, and a controller 7 (MCU controller is selected, and the model is GD32F103RET 6) is electrically connected to the electromagnetic door stopper 6; a travel switch 9 is arranged at the top of the door frame 1 corresponding to the top of the left door plate 2 (the travel switch 9 is a switch for detecting the rotation travel, the model is LXJMH 8104), a horizontal rod 10 which is horizontally arranged is rotationally connected to the bottom of the travel switch 9, and the horizontal rod 10 is pushed by the left door plate 2 to rotate in the closing process of the left door plate 2; the controller 7 is electrically connected with the 2 electric driving mechanisms 4 and the travel switch.
