Abstract
The utility model particularly relates to a connecting structure for a crank and a pedal center shaft of a body-building bicycle, which comprises a pedal center shaft and a crank, wherein a mounting hole matched with the pedal center shaft is arranged at the end part of the crank; the connecting structure is characterized in that the pedal center shaft and the mounting hole of the crank are in conical surface matching, the mounting hole of the crank is a taper hole with smaller inside and larger outside, and the inner end of the pedal center shaft is in frustum shape matched with the mounting hole. The connecting structure has the advantages of being convenient to install, good in self-tightening property, not easy to damage and long in service life. As the pedal center shaft and the mounting hole of the crank are in the conical surface matching, the connecting structure is good in self-tightening property, convenient to install, and can be automatically aligned; and simultaneously, the conical surface structure can transfer greater torque, is not easy to damage, and is long in service life.
Description
Technical field
The utility model is specifically related to Axile connection structure in a kind of crank of body-building bicycle and the pedal.
Background technology
At present, in bicycle and body-building bicycle field, the pedal axis is that the face of cylinder is connected with junction between the crank, and promptly the inner of pedal axis is cylindrical, and the mounting hole on the bent axle also is columniform, insert in the mounting hole of bent axle the inner of pedal axis, re-use bolt both are linked together, because in the process of scrunching, crank and pedal axis place are the places of stressed maximum, therefore this part influences vehicle operation often because of stressed excessive being damaged.
The utility model content
The purpose of this utility model is to solve in the crank of prior art body-building vehicle and the pedal shaft connection place because stressed excessive, the easy defective of damaging, provide the difficult damage in shaft connection place in a kind of crank and the pedal, Axile connection structure in the crank of the body-building bicycle of long service life and the pedal.
The utility model is achieved by the following technical solution:
It is Axile connection structure in a kind of crank of body-building bicycle and the pedal, comprise pedal axis and crank, the end of crank is provided with and pedal axis installation holes for matching, it is characterized in that being between the mounting hole of pedal axis and crank cone match, the mounting hole of crank is the little outer big taper hole in lining, and the inner of pedal axis is the taper type that mates with mounting hole.
The utlity model has advantage easy for installation, good, not fragile, long service life from sigma compactness.This adopts cone match between the mounting hole of pedal axis of the present utility model and crank, have good in sigma compactness, but automatic capturing easy for installation, cone structure can transfer larger torque simultaneously, and is not fragile, long service life.The utility model can also be applicable to the bicycle field.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
As shown in FIG.: 1 pedal axis; 2 thick washers; 3 bolts; 4 cranks.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in drawings: bent refined 4 lower end is equipped with pedal axis 1 by bolt 3, and bent refined 4 lower end is provided with mounting hole, and mounting hole is the little outer big taper hole in lining, and the inner of pedal axis 1 is the taper type that mates with mounting hole.Pedal axis 1 is a cone match with the mounting hole of crank 4.
The utlity model has good in sigma compactness, but automatic capturing easy for installation, cone structure can transfer larger torque simultaneously, and is not fragile, long service life.
