Abstract
The utility model relates to a folding bicycle, in particular to a folding bicycle with a forwardly folded rear wheel, which comprises a front wheel, a rear wheel, a bicycle head, a cross beam, a seat cushion and a rear wheel steel pipe used for fixing the rear wheel, wherein a folding device used for folding the rear wheel forwardly is arranged on the cross beam and the rear wheel steel pipe and comprises a limiting stopper and a revolving part, the revolving part and a seat cushion retracting rod are fixedly connected, the seat cushion is fixed on a bicycle frame via the seat cushion retracting rod, the limiting stopper is provided with a rotating shaft hole and a limiting arc-shaped groove, the revolving part is provided with a rotating shaft hole and a quick release parbuckle screw mounting hole, the distance between the rotating shaft hole and the limiting arc-shaped groove equals to that between the rotating shaft hole and the quick release parbuckle screw mounting hole, and a quick release parbuckle screw is mounted on the quick release parbuckle screw mounting hole. The utility model has the benefits that the bicycle is compact when folded, thereby saving space; and the seat cushion retracting rod is close to the cross beam when pushed toward the front wheel, so that the folding bicycle is more compact than the conventional open-close type bicycles with forwardly folded rear wheels, and the size after folding is greatly reduced, thereby resulting in portability and more attractive integral effect.
Description
Technical field
The utility model relates to a kind of folding bicycle, refers more particularly to the preceding fold type folding bicycle of a kind of trailing wheel.
Background technology
The fold type folding bicycle is to use the open-close type folder more before the present trailing wheel, and seat cushion expansion link and the spacing between crossbeam after folding are bigger, and is compact inadequately.
Based on the weak point of fold type folding bicycle before the above-mentioned existing trailing wheel, the inventor has designed the utility model " fold type folding bicycle before a kind of trailing wheel ".
The utility model content
The utility model at above-mentioned the deficiencies in the prior art technical matters to be solved is: provide a kind of trailing wheel preceding fold type folding bicycle.
The technical scheme that its technical matters that solves the utility model adopts is:
Fold type folding bicycle before a kind of trailing wheel, comprise front vehicle wheel, rear wheel, headstock, crossbeam, seat cushion and the trailing wheel steel pipe that is used for fixing rear wheel, described crossbeam and trailing wheel steel pipe place are provided with the folding device that will roll over before the trailing wheel, this folding device is made up of limiting stopper and revolving part, revolving part and seat cushion expansion link Joint, seat cushion is fixed on the vehicle frame by the seat cushion expansion link, limiting stopper is provided with rotation axis hole and spacing deep-slotted chip breaker, revolving part is provided with shaft hole and quick detach bottle rigging screw mounting hole, the spacing of rotation axis hole and spacing deep-slotted chip breaker equals the spacing of shaft hole and quick detach bottle rigging screw mounting hole, on quick detach bottle rigging screw mounting hole the quick detach bottle rigging screw is housed.Folding device is made up of limiting stopper and revolving part, limiting stopper is provided with rotation axis hole and spacing deep-slotted chip breaker, revolving part is provided with shaft hole and quick detach bottle rigging screw mounting hole, and quick detach bottle rigging screw mounting hole and spacing deep-slotted chip breaker align, and the quick detach bottle rigging screw is locked on the quick detach bottle rigging screw mounting hole.The spacing of rotation axis hole and spacing deep-slotted chip breaker equals the spacing of shaft hole and quick detach bottle rigging screw mounting hole.Bicycle is when folded state, and the seat cushion expansion link advances toward front-wheel, and is approaching with crossbeam, compact.
The rotation axis hole on the limiting stopper and the shaft hole of revolving part align with S. A. and are coupling, revolving part S. A. on limiting stopper rotates, revolving part is when rotating, the quick detach bottle rigging screw moves along spacing deep-slotted chip breaker, when bicycle during at deployed condition or folded state, with the locking of quick detach bottle rigging screw, revolving part just can and not unclamp around the limiting stopper rotation, is easy to carry.Described limiting stopper rear side offers the opening that is used to increase screen resilience.
The beneficial effect of fold type folding bicycle is before a kind of trailing wheel of the utility model:
Compact when folding, save the space, the seat cushion expansion link advances back and crossbeam approaching toward front-wheel, and is compacter more than folding bike before the existing open-close type trailing wheel, dwindles folding rear space volume greatly, is convenient for carrying, and whole structure is more attractive in appearance.
