When the roller shutter door needs to be closed, only the driving motor 31 needs to be controlled to rotate in the opposite direction, so that the connecting plate 51 and the door plate assembly 4 are driven by the transmission shaft 32 and the transmission rod 33 to rotate in the opposite direction along the vortex track 23, and re-enter the track groove 11 of the fixed track 1, and descend along the track groove 11, thereby closing the roller shutter door.

[0052] When a certain piece of hard door plate 41 on the door plate assembly 4 is damaged and needs to be repaired or replaced, two people can press the transmission plate 523 on the front side or the rear side of the connecting plate 51 connected to the damaged hard door plate 41 at the same time, so that it slides along the communication groove 511 away from the hard door plate 41, at this time, the transmission plate 523 drives the clamping block 52 to slide into the storage sliding groove 54 from the clamping groove 411 at one end of the hard door plate 41, and compresses the elastic top piece 56, at this time, the damaged hard door plate 41 can be removed in the front-rear direction, and a new hard door plate 41 is reinstalled to the original position in the front-rear direction, so that the clamping grooves 411 at both ends of the new hard door plate 41 are opposite to the clamping blocks 52 on the two connecting plates 51 respectively, and then the transmission plate 523 is loosened, at this time, the elastic top piece 56 is no longer pressed by the clamping block 52, and starts to release the elastic force accumulated during compression to reset, the clamping block 52 is re-slid into the clamping groove 411 on the new hard door plate 41 from the storage sliding groove 54 under the action of the elastic top piece 56, and at the same time, the clamping block 52 also synchronously drives the transmission plate 523 to reset when sliding, thereby completing the replacement of the damaged hard door plate 41.

[0053] When one of the connecting plates 51 or a component mounted thereon is damaged, first, the hard door plate 41 mounted on the connecting plate 51 is removed according to the above steps, then a supporting block is placed at the position of the hard door plate 41 to support the hard door plate 41 above it to avoid its falling. Then the hinge members 53 at the top and bottom of the connecting plate 51 are removed from the hinge shafts 513, at this time the damaged connecting plate 51 can be taken out from the track slot 11 of the fixed track 1. Due to the supporting effect of the supporting block, the falling of the other connecting plate 51 above the connecting plate 51 after it is taken out can be avoided.
