The fixed part 3 is fixed on the ceiling, and one end of the pull rope 54 far away from the winch is connected on the ceiling.

When the curtain 2 needs to be installed, the self-locking motor operates, so that one end of the telescopic connecting frame is located at one end of the lifting part 4, the self-locking motor is locked in a self-locking mode, then the driving machine 30 operates, the driving shaft 29 rotates, the transmission gear 22 is driven to move under the action of damping oil, the driving mechanism and the fixing mechanism are close under the action of the driving rack 21, the telescopic connecting frame contracts, finally, the two ends of the telescopic connecting frame are located on the lifting part 4, then the lifting device operates, the lifting part 4 descends, the two ends of the upper edge of the curtain 2 are respectively hooked by the driven hooks 42, and at the moment, the curtain 2 is loose, and the curtain 2 is shown in fig. 6 and fig. 7;

the lifting device operates, the lifting part 4 rises to the ceiling, then the self-locking motor operates, and the fixing mechanism moves to the fixing part 3 and then is locked in a self-locking mode, and the lifting device is shown in fig. 8; then the driving machine 30 is operated, the driving mechanism moves to the side far away from the fixing mechanism, the telescopic link is extended, and at this time, the curtain 2 is extended, (it should be noted that, in the process of extending the telescopic link, the length of the telescopic rod 7 is unchanged, the telescopic rod 7 rotates relatively, and under the action of the guide sleeve 10 and the guide rod 11, the hanging slide seat 6 always corresponds to the position of the middle part of the telescopic part, that is, the first limit plate 45 is positioned below the driving hook), (in addition, in the process of rotating the transmission gear 22, the transmission shaft 24 rotates, under the action of the damping oil, the damping gear 28 rotates, and drives the sliding rack 25 to move upwards to the proximity switch 27, see fig. 10; the second return spring 26 is extended), and after the curtain 2 is straightened, see fig. 9; the driving mechanism stops moving, the transmission gear 22 and the transmission shaft 24 stop rotating, the driving shaft 29 rotates in place, the sliding rack 25 moves downwards under the action of the second return spring 26, and the sliding rack 25 is disengaged from the proximity switch 27, see fig. 11; the proximity switch 27 sends a signal to the drive cylinder 38, which moves the drive machine, which moves in the direction of the second rod, under the action of the buffer spring 32, the driving plate 33 moves towards the pulling turntable 36, the clamping block 37 is matched with the clamping groove, the rotating shaft 35 is pulled to rotate, under the action of the damping oil, the pulling gear 34 rotates, under the action of the pulling rack, the pull rod 20 drives the piston 17 to move, since the liquid 16 is supplied to the cylinders 15, and the adjacent cylinders 15 are connected to each other by the pipe 14, so that when the pulling mechanism moves the piston 17 of one of the adjusting cylinders, pulling and moving the whole body, the liquid 16 will flow through the pipe to the adjacent cylinder 15, with the end effect that, when the pulling mechanism pulls one of the pistons, other pistons move for the same distance, so that the length of each telescopic rod 7 is always equal; here, each telescopic rod 7 is shortened by the pulling mechanism, see fig. 12; the supporting rod 39 approaches the groove 46, a limiting protrusion 57 for limiting the supporting rod 39 is arranged on the inner wall of the groove 46, when the supporting rod 39 abuts against the limiting protrusion 57 (at this time, the telescopic rod 7 cannot be continuously shortened, the rotating shaft 35 is pulled to rotate in place, and the pulling gear 34 cannot be continuously rotated), the driven wheel 40 corresponds to the driving wheel 47 in position, the protrusion 41 is located at the upper end of the vertical chute 50, and the upper edge of the curtain 2 is located between the first limiting plate 45 and the second limiting plate 51 (the limiting plate functions to keep the stability of the curtain 2 when the needle passes through the curtain 2), see fig. 13; the servo motor drives the driving wheel 47 to rotate 180 degrees, the driven wheel 40 also rotates 180 degrees under the action of the protrusion 41 and the vertical chute 50, in the process of the rotation, the driving needle 49 slowly moves towards the curtain 2, the driven needle 44 slowly comes out of the curtain 2, the driving needle 49 penetrates through the upper edge of the curtain 2, then the driven needle 44 is separated from the curtain 2, and after the 180-degree rotation is finished, the protrusion 41 is positioned at the lower end of the vertical chute 50, see fig. 14; in the process, the driver always keeps the running state, so that the curtain 2 keeps the tense state and the pricker can conveniently penetrate through the curtain;

then the driving machine stops running, under the action of the first return spring 19, the telescopic rod 7 slowly recovers the length, the supporting rod 39 slowly descends, and the driven puncture needle 44 and the driving puncture needle 49 are far away; see fig. 15 and 16; the curtain 2 can be freely dragged after the installation is finished, and the hanging sliding seats 6 are uniformly distributed because the telescopic rods 7 are the same in length, so that the curtain 2 has a good display effect.

When curtain 2 needs to be unloaded, the fixing mechanism is fixed at one end of the telescopic connecting frame, then the driving mechanism runs, the telescopic connecting frame extends, after curtain 2 is tightened, and in the same way as above, the telescopic rod 7 can be shortened, then when the driven wheel 40 rises to the position of the driving wheel 47, curtain 2 is located between the first limiting plate 45 and the second limiting plate 51, the protrusion 41 is located at the lower end of the vertical chute 50, the servo motor rotates 180 degrees, in the process, the driven puncture needle 44 firstly penetrates through curtain 2, then the driving puncture needle 49 leaves curtain 2, then the self-locking motor runs to one end of the lifting part 2 and then self-locks, the driving machine rotates reversely, the driving mechanism stops after moving to the other end of the lifting part 4, so far, the two ends of the telescopic connecting frame are located on the lifting part 4, the lifting device runs, the lifting part 4 descends, and the curtain 2 can be replaced.

The driven wheel 40 has a large rotation resistance, so that when the driven wheel 40 is separated from the driving wheel 47, the driven wheel 40 cannot rotate freely, and the protrusion 41 and the vertical sliding groove 50 can be smoothly matched.
