Lift and rotation mechanism for quick door-opening device

A lift and rotation mechanism for a quick door-opening device, the quick door-opening device comprising a movable circular door, an end flange, and the lift and rotation mechanism, wherein the lift and rotation mechanism comprises:

• (a) a lift component, wherein the lift component is installed in a central position of an outer surface of the movable circular door and is arranged to move the circular door along a vertical direction, the lift component comprising a first motor, a screw rod, a tubular body, a circular pipe, and an annular connection, wherein:
• (i) a power-output end of the first motor is connected to one end of the screw rod and an other end of the screw rod is connected to one end of the circular pipe;
• (ii) the tubular body is provided at one end with a connection portion, the connection portion being fixedly connected to one end of a coupling component, wherein parts of the circular pipe and the screw rod are disposed within the tubular body;
• and
• (iii) the annular connection removably and fixedly connects an other end of the circular pipe to the circular door;
• (b) a rotary component, wherein the rotary component rotates the quick door-opening device and the lift component in a horizontal direction, the rotary component comprising a second motor, a rotary shaft, a supporting seat, and a circular disk, wherein:
• (i) an output shaft of the second motor is removably connected to one end of the rotary shaft to drive the rotary shaft;
• (ii) the rotary shaft is disposed in the supporting seat, and the supporting seat is removably connected to the end flange of the quick door-opening device;
• and
• (iii) the circular disk is fixedly connected to an other end of the rotary shaft, and the circular disk is fixedly connected to the coupling component;
• and
• wherein the coupling component comprises a bar-shaped plate, a tubular connection, and a reinforcing member, wherein:
• (i) the bar-shaped plate is provided with openings at both ends thereof, with the opening at one end being passed through by the circular pipe and the opening at an other end being passed through by the tubular connection;
• (ii) the tubular connection is welded with the a bar-shaped plate;
• and
• (iii) the reinforcing member is welded respectively with the a bar-shaped plate and with the tubular connection above the a bar-shaped plate.
