The utility model discloses a theory of operation and use flow: when the door is opened, as shown in fig. 5, the driving shaft 6 is driven by the chain 7 and the motor 8 to rotate counterclockwise, at this time, the connecting rod 22 approaches to the connecting seat 11 and forms a clamping with the clamping groove 15, so as to realize the connection between the connecting seat 11 and the connecting rod 22, and at the same time, the limit connecting block 14 also moves along the limit groove 13, and the limit connecting block 14 does not separate from the connecting seat 11, so as to ensure that the connecting seat 11 forms a stable location, and then along with the continuous rotation of the driving shaft 6, the connecting seat 11 and the locking and unlocking piece 16 generate a relative motion trend, and simultaneously form a fit with the sliding inclined plane 20, so that the locking and unlocking piece 16 and the connecting seat 11 slide relatively, so as to separate the connecting seat 11 and the locking and unlocking piece 16, and at the same time, the connecting seat 11 and the inner sleeve 5 rotate counterclockwise synchronously under the limitation of the clamping with the connecting, gradually approaching the fixing nail 21 and forming limitation through the fixing nail 21, in this state, the inner sleeve 5 continues to rotate, the inner sleeve 5 pushes the connecting seat 11 through the connecting clamping rod 22, the connecting seat 11 pushes the outer sleeve 4 through the fixing nail 21, and therefore the outer sleeve 4 also rotates anticlockwise, so that the retracting operation of the roller shutter door body 2 is effectively achieved, and the door opening effect is achieved;

when the door of the rolling door is closed, as shown in fig. 6, the locking and releasing piece 16 is clamped with the locking groove 10 through the resilience of the spring 19, at this time, the inner sleeve 5 and the driving shaft 6 rotate clockwise, the inner sleeve 5 drives the connecting seat 11 to rotate through the matching of the structures such as the limiting connecting block 14, the limiting groove 13, the limiting end 12 and the like, and the connecting seat 11 drives the outer sleeve 4 to rotate through the locking and releasing piece 16 and the locking and releasing seat 9, so that the door closing effect of the rolling door body 2 is realized;

in the door closing operation, if the lower end of the rolling shutter door body 2 is blocked by an obstacle, the rolling shutter door body 2 cannot move downwards, the supporting force applied to the rolling shutter door body 2 acts on the outer sleeve 4 to limit the outer sleeve 4 from rotating, and the inner sleeve 5 and the driving shaft 6 still have a tendency of rotating, so that the locking and releasing piece 16 and the connecting seat 11 are subjected to opposite acting forces, and because the locking and releasing piece 16 and the connecting seat 11 form a main force connection through the friction inclined surface 23 during clockwise rotation, a certain static friction force exists between the locking and releasing piece 16 and the connecting seat 11, when the opposite acting forces are greater than the static friction force, the locking and releasing phenomenon occurs between the locking and releasing piece 16 and the connecting seat 11, as shown in fig. 7, the inner sleeve 5 and the driving shaft 6 idle clockwise under the driving of the motor 8, even if the rotating action is released when the driving of the motor 8, the connection joints between the components are prevented from being damaged, the outer sleeve 4 is still kept still under the limitation of the roller shutter body 2, when the barrier is cleared, the outer sleeve 4 automatically rotates under the action of the gravity of the roller shutter body 2, and the locking and releasing seat 9 gradually approaches to the connecting seat 11 along with the rotation of the outer sleeve 4, so that the reconnection between the locking and releasing seat 9 and the connecting seat 11 is realized;

if the locking and unlocking seat 9 is not connected with the connecting seat 11 after the rolling shutter door body 2 is completely descended, the driving shaft 6 can be driven to rotate anticlockwise and be connected under the anticlockwise rotation.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
