Abstract
The invention provides a foldable front three-wheel bicycle, which comprises two front wheels, a rear wheel, handles, a sprocket transmission mechanism, foot pedals, a saddle, a chassis, a telescopic handle supporting tube, a basket, a telescopic rear wheel installation tube and a saddle supporting and folding mechanism. The telescopic handle supporting tube can contract to be accordant with the upper edge of the basket; the saddle supporting and folding mechanism can be contracted, folded and adhered to the telescopic rear wheel installation tube; and the telescopic rear wheel installation tube can drive the connected components to be contracted to the lower part of the chassis and causes the rear wheel to be arranged below the handle to form a wheelbarrow. Before being folded, the bicycle is a whole one which can be ridden especially to go shopping. After arriving at the shopping malls, the bicycle can be turned into the wheelbarrow by slightly folding which can be pulled into the shopping malls to go shopping. The purchased goods can be put into the basket until being pulled out of the shopping malls. After going out of the shopping malls, the wheelbarrow can be turned back into the bicycle again which can be ridden to go home, which is very convenient and trouble-saving.

Fig. 7 is the structural representation of looking closely of folding type front three-wheeled bicycle of the present invention.
The specific embodiment
Below in conjunction with specific embodiment the present invention is described further.
Referring to Fig. 1; Cooperation is referring to Fig. 7; Folding type front three-wheeled bicycle of the present invention comprises two front-wheels 1, trailing wheel 2, telescopic trailing wheel mounting pipe 3, handle 4, telescoping handle support tube 5, chain wheel driving mechanism 6, pedal 7, saddle 8, saddle supporting folding mechanism 9, chassis 10 and a bicycle basket 11.Telescoping handle support tube 5 is installed in respectively on the chassis 10 with bicycle basket 11, and trailing wheel 2, chain wheel driving mechanism 6, pedal 7 and saddle supporting folding mechanism 9 are installed in respectively on the telescopic trailing wheel mounting pipe 3.Telescoping handle support tube 5 may contract to suitable for reading concordant with bicycle basket 11; It is folding attached on the telescopic trailing wheel mounting pipe 3 that saddle supporting folding mechanism 9 is collapsible, telescopic trailing wheel mounting pipe 3 can drive institute's bonded assembly elements constrict to 10 bottoms, chassis and make trailing wheel 2 be positioned at handle 4 under form hand barrow.
Telescopic trailing wheel mounting pipe 3 among the present invention is made up of interior pipe 31, middle pipe 32 and outer tube 33 three-joint pipes order suit; The front end of interior pipe is fixedly connected on the downside crossbeam middle part of chassis 10 front ends; The front end of middle pipe is provided with spacing chimb 321; Fixedly connected to the inner side a bracing frame 322 at spacing chimb, between the upside crossbeam of pipe 32 and 10 rear ends, chassis, trailing wheel 2, chain wheel driving mechanism 6, pedal 7 and saddle supporting folding mechanism 9 were installed in respectively on the outer tube 33 during this bracing frame can be supported on.
