Abstract

The invention discloses a safe and realizable electric convolute limit detection device capable of accurately positioning. The detection device comprises a core tube. The core tube is provided with an opening, the interiors of two ends of the core tube are respectively provided with a core tube plug and a core tube rotor, one end of the core tube is movably arranged in a left end cap through the core tube plug, the other end of the core tube is connected with an output shaft of a synchronous motor arranged in a vibration damping motor seat through the core tube, the vibration damping motor seat at the lower end of the core tube rotor is fixedly provided with a switch mounting seat in which an upper limit detection switch and a lower limit detection switch are respectively arranged. The limit detection device has the advantages of overcoming the defect of inaccurate positioning of the prior upper limit detection switch and the prior lower limit detection switch caused by easily moving positions, ensuring accurate of an upper limit position and a lower limit position of a convolution object, having reliable guarantee of overall safe performance at the same time, and reducing maintenance cost greatly.

Description

technical field [0001] The invention relates to a limit detection device for detecting the position of winding objects in an electric shutter. Background technique [0002] As we all know, electric roller blinds used for winding screens, curtains and other winding objects are equipped with a controller and a limit detection device. The structure of the limit detection device usually includes: a screw fixedly connected to the output shaft of the motor, The screw rod is provided with a travel nut through the thread, and the upper and lower limit detection switches are respectively arranged on both sides of the screw rod, and the positions of the upper and lower limit detection switches can be adjusted. The controller that runs the motor is connected. During production debugging, adjust the relative positions of the upper and lower limit detection switches and the stroke nut, so that the stroke between them and the stroke nut corresponds to the upper and lower strokes of windi...
