A bicycle pedal mounting structure comprising:
- a pedal assembly comprising:
- a pedal for adapting to be stepped on by a rider;
- a spindle having a first end pivotally mounted on the pedal, such that the spindle is able to pivotally rotate relative to the pedal, the spindle having a connecting portion axially formed thereon and protruding from a second end thereof opposite to the first end, the connecting portion having a through bore radially defined therein and formed two openings on an outer periphery thereof, an abutting ball received in the through bore and movably engaged with one opening, the opening having a diameter less than an outer diameter of the abutting ball, a fastener received in the through bore and fixedly threaded in the other opening, a second spring compressively received in the through bore and having two ends respectively abutting against the abutting ball and the fastener;
- a pivot sleeve coaxially and fixedly sleeved on the second end of the spindle, the pivot sleeve having a limiting flange annularly formed on an outer periphery of a first end thereof, the pivot sleeve having a receiving groove annularly defined in an inner periphery of a second end thereof opposite to the first end for corresponding to the connecting portion of the spindle, the connecting portion having an outer diameter less than an inner diameter of the receiving groove, the pivot sleeve having at least two bores radially defined in the second end and extending therethrough for communicating with the receiving groove, a positioning ball movably received in each of the at least two bores;
- a slidable sleeve coaxially and slidably sleeved on the pivot sleeve, the slidable sleeve having a through hole axially defined therein and extending therethrough, the slidable sleeve having an annular recess defined in an inner periphery of the through hole for selectively engaging with the positioning balls, the slidable sleeve having an inserted recess defined in the inner periphery of the through hole thereof, the slidable sleeve having a limiting flange annularly formed on the inner periphery of the through hole and located between the annular recess and the inserted recess;
- and
- a first spring coaxially sleeved on the pivot sleeve and compressively received in the inserted recess of the slidable sleeve, the first spring having two ends respectively abutting against the limiting flange of the pivot sleeve and the limiting flange of the slidable sleeve;
- a retaining sleeve detachably and coaxially receiving the second end of the spindle, the retaining sleeve having a retaining hole axially defined therein for correspondingly receiving the connecting portion, the retaining sleeve having a plurality of indents spacedly defined in an inner periphery of the retaining hole for selectively engaging with the abutting ball, a first end of the retaining sleeve having an outer diameter less than the inner diameter of the receiving groove of the pivot sleeve, the retaining sleeve having a positioning groove annularly defined in an outer periphery of the first end thereof for selectively engaging with the positioning balls.
