Abstract

The invention relates to an energy-saving electric rolling shutter door capable of adjusting pre-torsion of a torsional spring. The energy-saving electric rolling shutter door comprises a bracket plate, a guide rail, a reel, a winding drum, a roller shutter, a rolling door machine, a stopper, the torsional spring and an adjusting rod. The winding drum is internally provided with an adjusting wheel, an anti-motion rod and anti-motion pins, the adjusting wheel and the reel are rotatably connected, and a plurality of countersinks are formed in the outer circumference of the adjusting wheel and the reel. The anti-motion rod is arranged on the radial outer side of the adjusting wheel, and is fixedly connected with the reel. The anti-motion pins are matched with the countersinks, after each anti-motion pin is inserted into each countersink, one end of each anti-motion pin outside the countersink can lean against the anti-motion rod, the winding drum at the corresponding position of the adjusting wheel is provided with a plurality of slots, one end of the torsional spring is fixedly connected with the inner wall of the winding drum, and the adjusting wheel is fixedly connected with the other end of the torsional spring . A driven chain wheel which is in transmission connection with a door rolling machine is arranged at one end of the winding drum, the adjusting rod can be inserted into each countersink through each slot, the diameter of the adjusting rod matches the diameter of each countersink. Torsion force of the torsional spring is convenient to adjust, the structure is simple, and energy and electricity are saved.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to an energy-saving electric rolling door capable of adjusting the pre-torque force of a torsion spring. Background technique [0002] Electric rolling shutter doors are widely used in stores, shopping malls, garages and other places. Electric rolling shutter doors are generally driven by a rolling door machine to rotate the reel, and drive the roller shutter wound on the reel to slide up and down along the guide rail to open and close the door. The utility model patent with authorized notification number CN206397411U discloses an energy-saving and power-saving electric rolling door. A planar scroll spring is arranged in the reel. The function of the planar scroll spring is to save effort in opening and closing the door curtain. When the door curtain is lowered, the drooping part of the door curtain becomes longer and heavier, and the rotation of the reel drives the flat scrol...
