The purpose of this utility model is to provide a kind of box-bag type folding bicycle of compactness, under the situation of hardware ﹠ tools, just can simply install the folded part of case and bag at short notice, becoming is bicycle, being again the case and bag that can load luggage and articles, is again the seat that the journey respite is used.

The purpose of this utility model is achieved in that a kind of box-bag type folding bicycle, comprise leading direction assembly, seat saddle assembly, assembly of drive gear, case and bag are made up of combination lock and the decoration casing that is positioned at its front and rear portions, leading direction assembly after folding is loaded in the front decoration casing, and seat saddle after the contraction and crank driving mechanism are loaded on the back and decorate in the casing.

Tap direction assembly by tap, front fork, front-wheel, turn to bindiny mechanism to form, leading lifting bar stretches into that front fork is interior and join with expansion sleeve, front fork is captiveed joint with the combination lock antetheca by turning to bindiny mechanism, front-wheel is equipped with in the front fork lower end.Described tap mainly is made up of leading lifting bar, left and right handlebar stem and connection catch gear thereof.

Crank driving mechanism is made up of drive axle, axis, chain, sprocket wheel, axle drive shaft, trailing wheel and rear brake wheel nave boss, and captives joint with the combination lock rear wall by connecting bridge.The seat saddle lifting bar that a saddle is equipped with in the upper end inserts in the drive axle and by seat saddle lifting fixer and is fixed on arbitrary position.Also be provided with the crank suspension member in the drive axle upper end, after folding, the crank step is just hung thereon.

Advantage of the present utility model is compact conformation; Assembly is convenient and swift, does not need by any hardware ﹠ tools; Purposes is various, behind the assembly the bicycle of band baggage container, promptly be the case and bag of a belt wheel after folding, it can adorn the required article of whilst on tour, simultaneously can be for people seat during as the journey respite.

Fig. 1 is the folding case and bag that become a belt wheel afterwards of the utility model.

Fig. 2 becomes a box-bag type bicycle behind the utility model stretching assembly.

Fig. 3 is the inner structure scheme drawing of box-bag type bicycle shown in Figure 2.
