The invention provides a reinforced type bicycle crank. The bicycle crank comprises a connecting handle, a fluted disc connecting part and a pedal connecting part; the fluted disc connecting part andthe pedal connecting part are fixedly connected with two ends of the connecting handle respectively; and a bent part is arranged on the connecting handle. The bicycle crank has the beneficial effectsthat the fluted disc connecting part and the pedal connecting part are arranged at two ends of the connecting handle and are used for connecting a fluted disc and pedals of a bicycle; meanwhile, the bent part is arranged on the connecting handle, so under the condition of the same interval, the stress surface is enlarged, the bearing capacity of the crank is improved, and a part of acting force isdissipated through a curved surface, so finally, the bent part generates a buffering effect on acting force which is applied to the pedals and then transmitted to the crank; and the crank is light inweight, high in strength, high in bearing capacity and long in service life.

    本发明提供了一种加强型自行车曲柄,包括连接柄、齿盘连接部、脚蹬连接部,所述齿盘连接部和脚蹬连接部分别固定连接在连接柄的两端,且在所述连接柄上设有弯折部。本发明有益效果:在连接柄两端设置齿盘连接部和脚蹬连接部,用于连接自行车齿盘和脚蹬,同时,在连接柄上设置弯折部,在相同间距的条件下,加大受力面,增加了曲柄的承载能力,并且采用曲面消散一部分作用力,最终使得弯折部对施加给脚蹬进而传递到曲柄上的作用力产生缓冲作用;该曲柄重量轻、强度高,承载能力强,使用寿命长。
