Rapid garage door

Abstract

The invention discloses a rapid garage door which comprises a door frame and a door curtain. The door curtain comprises a rope rolling shaft, ropes, torsion springs and movable shafts. The upper ends of a first row of the torsion springs are connected with a fixed shaft, the lower ends of the first row of the torsion springs are connected with the first movable shaft, the upper ends of a second row of the torsion springs are connected with the first movable shaft, and the lower ends of the second row of the torsion springs are connected with the second movable shaft. The upper ends of a last row of the torsion springs are connected with the third movable shaft, the lower ends of the last row of the torsion springs are connected with the rope connecting movable shaft located at the lowest end of the door curtain, the upper ends of the ropes are connected with the rope rolling shaft, and the lower ends of the ropes are connected with the rope connecting movable shaft. The rope rolling shaft is supported by a shaft seat and a motor seat, one end of the rope rolling shaft is connected with an output shaft of a motor, the motor is installed on the motor seat, and the upper ends and the lower ends of the shaft seat and the motor seat are respectively connected with the lower portion of a door upper frame and tops of door side frames. Long grooves are formed in the door side frames and used for displacement of the movable shafts. The fixed shaft is fixed on the upper portions of the door side frames through shaft seat plates. The rapid garage door has the advantages of being rapid in the speed of door opening and closing, good in permeability, small in occupied places at the top, the bottom, the left and the right, good in safety and capable of withstanding the low-speed impact of a motor vehicle. The rapid garage door is very suitable for a stereo garage.

Description

technical field [0001] The invention relates to a garage door. Background technique [0002] Existing existing public garage doors have glass doors, sliding gates, rolling gates, and flat doors. Its shortcomings are: glass door: good permeability, but the left and right positions are large, fragile, and unsafe; retractable and rolling shutter doors: due to structural reasons, the speed of opening and closing the door is slow and takes a long time, which affects the garage. Access car speed; flat door: the required position is large, and the permeability is poor. Contents of the invention [0003] The object of the present invention is to provide a fast garage door to overcome the above disadvantages. It has fast opening and closing speed, good permeability, small space occupied by up, down, left, and right sides, good safety, and can withstand low-speed impact of automobiles. This kind of door is very suitable for three-dimensional garages. [0004] The present inventio...
