Novel anti-reverse laundry rack hand-cranking machine

A novel anti-reverse laundry rack hand-cranking machine comprises I-shaped wheels wound with steel wire ropes and rolling stopper pins, the surface of a wheel shaft of each I-shaped wheel is provided with a rolling stopping clamping part, one end of each rolling stopper pin is movably hinged, and the other end of each rolling stopper pin is close to the surface of the wheel shaft of the corresponding I-shaped wheel and is matched with the rolling stopping clamping part on the surface of the wheel shaft of the I-shaped wheel; when the I-shaped wheels roll reversely, the steel wire ropes are released to make the rolling stopping clamping parts on the surfaces of the corresponding wheel shafts of the corresponding I-shaped wheels totally exposed, the rolling stopper pins head on abut against the rolling stopping clamping parts to be clamped, and continuous reverse rolling of the I-shaped wheels is prevented; when the I-shaped wheels roll forwards, the rolling stopper pins roll following the rolling stopping clamping parts, and the steel wire ropes are smoothly wound on the I-shaped wheels. The novel anti-reverse laundry rack hand-cranking machine further comprises rolling stopper pin torsional springs which press the rolling stopper pins to be close to the surfaces of the corresponding wheel shafts of the corresponding I-shaped wheels. The side face of the wheel shaft of each I-shaped wheel can be provided with a steel wire rope fixed grain hidden groove and can be also provided with a steel wire rope hidden groove which can hide an initial section of steel wire rope, and each steel wire rope hidden groove is communicated with the corresponding steel wire rope fixed grain hidden groove. By means of the novel anti-reverse laundry rack hand-cranking machine, the steel wire ropes are not prone to fracture and disengagement, and the service life and the safety are effectively improved.
