Problems solved by technology

[0002] Bicycle is a commonly used means of transportation, which has the advantages of energy saving, environmental protection, and convenient use; the pedals in the current bicycles are connected to the crank through the connecting shaft pierced in the pedal, that is, the pedal is connected to the connecting shaft in rotation, and the connecting shaft is connected to the crank. But because the crank can rotate relative to the frame of the bicycle, and because the connecting shaft and the crank are threaded, in this way, when the connecting shaft and the crank are tightened with a wrench, the crank tends to rotate relative to the frame , which will bring inconvenience to the tightening process of the connecting shaft and the crank, that is, there is the disadvantage of inconvenient assembly of the pedal and the crank

Abstract

The invention discloses a bicycle with pedals convenient to install. The bicycle comprises a bicycle frame, a crank is rotationally connected to the middle of the bicycle frame, pedals are installed at the two ends of the crank respectively, a supporting shaft penetrates through each pedal, the pedals are rotationally connected with the supporting shafts, the outer end of each supporting shaft isprovided with an end with the outer diameter larger than that of the corresponding supporting shaft, and the inner end of each supporting shaft penetrates through the corresponding pedal and then is clamped with a first clamping spring in a matched mode; a square inserting part is integrally formed in the middle of the inner end of the supporting shaft, the inserting part is inserted into a squareinserting groove in the outer side face of the crank, a plug pin coaxial with the supporting shaft is integrally formed in the middle of the inner end of the inserting part, and the plug pin movablypenetrates through the crank, then stretches out of the crank and is clamped with a second clamping spring in a matched mode; the supporting shaft arranged in the pedal in the penetrating mode is assembled with the crank in a matched and clamped mode, in this way, when the pedal and the crank are assembled, tools such as a wrench do not need to be used, and therefore convenience can be brought toinstallation of the pedal.
