Planar structure scheme drawing when Fig. 2 is each component part expansion of the utility model;
Fig. 3 is the planar structure scheme drawing after each component part of the utility model folds.
The specific embodiment
To accompanying drawing 3, embodiment of the present utility model is described below in conjunction with accompanying drawing 1:
A kind of folding pedal mechanism of bicycle is provided, it is by the crank 1 of captiveing joint with bicycle middle shaft, with crank 1 pivotally attached connecting rod 2, form with connecting rod 2 pivotally attached pedals 4, pedal 4 and crank 1 are folding be fitted on the connecting rod 2 after, make the bar length direction of connecting rod 2 with the axial vertical of bicycle middle shaft or be similar to vertical; The axial coincidence of the axle sleeve 12 of axial and crank 1 front end of described bicycle middle shaft.
After described pedal 4 and crank 1 folded and be fitted on the connecting rod 2, the axle sleeve 12 of crank 1 front end can be contained in the notch 41 of pedal 4.
Described crank 1 is provided with projection 11, and connecting rod 2 is provided with projection groove 21 with crank 1 bonded assembly one end, connecting rod 2 and first column pin hole 22 of crank 1 bonded assembly one end and second column pin hole, the 111 same axial settings on the projection 11.
First column pin hole 22 on described connecting rod 2 and crank 1 bonded assembly one end and first column pin hole 22 on connecting rod 2 and pedal 4 bonded assemblys one end, its upper end is square, the lower end is rounded, and the upper end 51 of employed pin 5 is square, the lower end of pin 5 52 rounded and described first column pin holes 22 match.
In the middle of the 3rd column pin hole 311 in the middle of described on the contiguous block 3 is arranged in the roller 31 of contiguous block 3 and be square.
Be provided with convex platform 26 and lower bulge 24 in the contiguous block groove 25 in the middle of described, convex platform 26 is provided with the square opening part of first column pin hole 22, lower bulge 24 is provided with the circular port part of first column pin hole 22, roller 31 contracts of middle contiguous block 3 are gone into 24 of convex platform 26 and lower bulges, contiguous block 3 is with after pedal 4 is connected in the middle of making, rotary connection with connecting rod 2, be convenient to the folding of pedal 4.
