Bicycle ratchet wheel assembly convenient to lubricate

The invention discloses a bicycle ratchet wheel assembly convenient to lubricate, and relates to the technical field of bicycle ratchet wheel assemblies, the bicycle ratchet wheel assembly comprises a rotating shaft, a linkage shaft, a ratchet wheel and a protective shell, one side of the rotating shaft is fixedly connected with the linkage shaft, one end of the linkage shaft is in threaded connection with the ratchet wheel, and the protective shell is installed on the outer wall of the ratchet wheel. A rapid safe lubricating mechanism is arranged on the arc surface of the linkage shaft, a lubricating pretreatment mechanism is arranged on the inner wall of the protective shell, a triangular block can pop out of an auxiliary groove again by means of the elastic force of a spring, the effect of fixing the adjusting plate is achieved, the adjusting plate is prevented from continuously rotating, and at the moment, only the rear wheel of the bicycle needs to be rotated; when the ratchet wheel rotates, the quick sa
