Referring to fig. 8 to 11, which are respectively an axial view of the telescopic unit during engagement and a top view of the telescopic unit during movement and an axial view of the first slider 26, the principle of the engagement of the shaped gear 22 with the transmission cylinder 24 is as follows: when the lifting frame 12 ascends, the first slide block 26 is driven to ascend together, at the moment, the first slide block 26 is pushed by the fourth spring 28 to be clung to the first limit block 27, the first limit block 27 is pulled by the fifth spring 32 to enable the first cylindrical guide rail 29, the first slide block 26 and the second slide block 30 to be always kept at the same position in the ascending process, therefore, the contact position of the second driving shaft 20 is always the same position when just contacting with the first slide block 26, the front end of the second driving shaft 20 can be inserted into the annular guide groove along the annular slope of the first slide block 26, the annular guide space of the first slide block 26 can ensure the relative position when the special-shaped gear 22 is meshed with the transmission cylinder 24, the lower end of the gear teeth of the special-shaped gear 22 is chamfered, the upper end of the transmission cylinder 24 is hemispherical, the transmission cylinder 24 is vertically installed in the guide groove of the first slide block 26 through the third spring 25, the transmission cylinder 24 can move up and down along the first sliding block 26, the third spring 25 makes the transmission cylinder 24 always keep at the highest point when no external force acts, therefore, when the gear teeth of the special-shaped gear 22 vertically contact with the transmission cylinder 24 and interfere in the meshing process, the transmission cylinder 24 can overcome the thrust of the third spring 25 to move down, at this time, the lifting frame 12 is still in the lifting process, taking the top direction as reference, the second driving shaft 20 and the inner ring of the second overrunning clutch 21 fixedly connected with the second driving shaft are in the anticlockwise rotating state, so that the outer ring can freely rotate in the clockwise direction, the outer ring can freely rotate when the speed of the anticlockwise direction does not exceed the speed of the inner ring, and simultaneously, because the front end of the second driving shaft 20 can drive the first sliding block 26 to move a small distance along the direction overcoming the work of the fourth spring 28 and the fifth spring 32 in the process of inserting into the annular groove along the slope of the first sliding block 26, the interference contact of the teeth of the shaped gear 22 with the driving cylinder 24 is misaligned by a small distance, and since the contact surface is spherical, the third spring 25 pushes the driving cylinder 24 upward to rotate the shaped gear 22 by a small range, so that the teeth can be inserted into the space between the driving cylinders 24 until the lifting process is finished and the engagement is completed.
Referring to fig. 12 and 13, an axial view after the clothes airing rod 35 enters the self-locking state and an axial view when the clothes airing rod 35 is completely extended are shown, when weather changes and the clothes airing rod 35 needs to be extended out of or retracted into the balcony, with reference to a top view direction, after the lifting frame 12 enters the self-locking state, the telescopic control key is pressed, the control part receives a signal and controls the motor 2 to be electrified to drive the first gear 4 to rotate clockwise, so as to drive the mutually meshed second gear 5, the first driving shaft 7 and the inner ring of the first overrunning clutch 8 to rotate anticlockwise, the third gear 6, the second driving shaft 20 and the second overrunning clutch 21 to rotate clockwise, at the moment, the outer ring of the first overrunning clutch 8 cannot rotate, the outer ring of the second overrunning clutch 21 can be driven by the inner ring to move clockwise together, the special-shaped gear 22 can be driven by the outer ring of the second overrunning clutch 21 to move clockwise, the special-shaped gear 22 is meshed with the transmission cylinder 24, and the guide groove of the first sliding block 26 can ensure the relative position of the special-shaped gear 22 and the transmission cylinder 24 during meshing transmission, so that the special-shaped gear 22 rotates clockwise to drive the first sliding block 26 to do reciprocating motion through the transmission cylinder 24, the first sliding block 26 drives the second sliding block 30 and the clothes-horse 35 to do reciprocating linear motion through the first cylinder guide rail 29, when the special-shaped gear extends to the farthest end, the photoelectric switch 33 detects the gear rack 34 for the first time, the motor 2 is powered off and extends out completely, when the telescopic control key is pressed down again, the control part receives signals and controls the motor 2 to be powered on again to drive the third gear 6 to continue to rotate clockwise, and therefore the clothes-horse 35 continues to do reciprocating linear motion, and when the photoelectric switch 33 detects the gear rack 34 again, the motor 2 is powered off and retracts completely.
Referring to fig. 4 to 7, which are a front view of the self-locking unit, an axial view of the self-locking unit, a process from an unlocked state to a self-locked state of the self-locking unit, and a process from the self-locking state to the unlocked state of the self-locking unit, when the clothes rod 35 needs to be lowered, the lowering control key is pressed with reference to a top view direction, the lifting frame 12 is in the self-locking state at this time, the self-locking needs to be released first and then lowered, the control part controls the motor 2 to be powered on first and rotate counterclockwise, so that the lifting frame 12 continues to rise, the lifting frame 12 drives the male head 13 of the self-locking switch to continue to move upward along the self-locking chute of the female head 16 of the self-locking switch, when the male head 13 of the self-locking switch abuts against the second peak section 41 of the female head 16 of the self-locking switch, the female head 16 of the self-locking switch, after the unlocking is finished, the motor 2 starts to be electrified reversely to drive the first gear 4 to rotate clockwise, so as to drive the second gear 5, the first driving shaft 7 and the inner ring of the first overrunning clutch 8 which are meshed with each other to rotate anticlockwise, the third gear 6, the second driving shaft 20 and the second overrunning clutch 21 to rotate clockwise, and the lifting frame 12 is unlocked, so that the lifting rope 11 is driven to descend by the self-gravity of the lifting frame 12, so as to drive the rope winding wheel 9 and the outer ring of the first overrunning clutch 8 to rotate anticlockwise together, because the anticlockwise rotation speed of the outer ring of the first overrunning clutch 8 cannot exceed the anticlockwise rotation speed of the inner ring thereof, the speed of the outer ring and the speed of the inner ring are kept consistent, so that the descending power source of the lifting frame 12 is the self-gravity, but the descending speed is controlled by the motor 2, in the descending process, after the special-shaped gear, no matter the clothes-horse 35 is stretched out or not, the clothes-horse 35 can be pulled by the fifth spring 32, so that the clothes-horse 35 is kept in a withdrawing state, and when the lifting frame 12 touches the travel switch 17 arranged in the second limiting block 37, the motor 2 is powered off, and the descending is completed.
