Abstract

A high-stability electric soft roller shutter door relates to electric soft roller shutter doors, comprising an actuator, a support frame, a door spindle, a roller, a door curtain, a cross beam and a door frame; driving sprockets are respectively arranged at both ends of the door spindle; the bottom of the door frame is provided with a driven sprocket; a drive chain is wound between the driving sprocket and the driven sprocket at each side; both ends of the cross beam are respectively connected with the drive chains at both sides; a spring is wound on the door spindle; one end of the spring is connected with a boosting sleeve and the other end thereof is connected with the roller; a transverse stop pin is arranged on the roller and a vertical stop pin is arranged on the door spindle. The electric soft roller shutter door can effectively prevent untight closing caused by wind force, prevent the door curtain from swaying along with the cross beam, prevent the door curtain from artificial opening arbitrarily and ensure the door curtain to be rapidly and stably opened and closed and the working performance to be safe and reliable.

Description

technical field [0001] The invention relates to a soft rolling shutter electric door. Background technique [0002] The existing soft rolling shutter electric door is mainly composed of a driver, a support frame, a door shaft, a roller, a door curtain, a beam and a door frame. The driver is connected to the door shaft, and the door shaft is fixedly connected to the roller. In the lower part, the two sides of the door curtain between the roller and the crossbeam and the two ends of the crossbeam are placed in the door frame. When the door is opened, the driver drives the door shaft and the roller to rotate, and the roller winds up the door curtain. When the door is closed, the driver acts in reverse, and the door curtain falls by the limited gravity of the beam. The above-mentioned soft rolling shutter electric door is widely used in places that need to quickly block the environment on both sides of the door, such as the entrance and exit of the logistics warehouse. The sof...
