8332, 8333 namely can realize relatively rotating seatpillar 15 by bearing 143, namely remove at the bottom of saddle 833 and seatpillar 15 between spacing, can carry out as required adjustment in direction, when adjustment in direction complete, unclamp button connecting handle 146, spring 145 recovers elastic deformation button 142 is ejected, again realize button 142 and the engagement of rotating tooth 144, namely fixed being connected of base 833 and seatpillar 15, mode by this light and handy pressing keys connecting handle 146 namely can realize adjusting the adjustment in direction between all parts easily.Principle is basically identical therewith for all the other 3 rotary joints, no longer continues tired stating at this.

Referring to Figure 24, front upset joint 9 comprises the upper adaptor union 91 that connects the front upper pipe 11 of car beam, the lower pipe connection 92 that connects car beam 1, button wheel 93, cushion block 94, self-locking lock pawl 95, pin 96, lock pawl orienting lug, dovetail furrow enclosing cover and spring.wherein go up adaptor union 91 and are connected coaxial connection with lower pipe connection, upper adaptor union 91 can rotate around the axle center, button wheel 93 passes the through hole of lower pipe connection 92 correspondences, one end is by being threaded into cushion block 94, cushion block 94 is taken turns by button and is limited in lower pipe connection 92 inboards, can move axially by the major axis that screws or unscrew along button wheel 93 that button is taken turns, pin 96 1 ends insert in upper adaptor union 91, after the cover upper spring with the cavity 911 that is built in adaptor union 91 belows in self-locking lock pawl 95 fixing, the other end is limited in adaptor union 91 outsides, self-locking lock pawl 95 is limited on lock pawl orienting lug at its back simultaneously, can move along the direction of lock pawl orienting lug, the dovetail furrow that lock pawl orienting lug opposite side is fixed in adaptor union 91 simultaneously covers outward, self-locking lock pawl 95 padlock shapes and cushion block 94 padlock shape complementarities, when the joint 9 of overturning needs the contact locking, first back-out button wheel 93, cushion block 94 is along with the twisting displacement inward vertically of button wheel 93, from linking closely state-transition for relaxing with self-locking lock pawl 94, pull pin 96, driving self-locking lock pawl 95 moves outward along lock pawl orienting lug, thereby remove the lock-out state of self-locking lock pawl 94 and cushion block 94, namely removed the locking of upper adaptor union 91 and lower pipe connection 92, upper adaptor union 91 can be drilled the axle center at this moment and be carried out 180 degree upsets, thereby drive the upset of whole front fork assembly 3 and front-wheel, when the joint 9 of overturning needs locking, forwarding upper adaptor union 91 to tangent plane with lower pipe connection 92 overlaps, self-locking this moment lock pawl 95 is because the effect of spring is forced in cushion block 94 padlocks, screw button wheel 93 this moment, being about to cushion block and self-locking lock pawl 94 links closely, self-locking lock pawl 94 and the friction force of cushion block contact surface are increased, can't extract pin 96 unlocks.

referring to Figure 25, rear upset joint 16 is mainly by the transposition joint 161 of captive joint back vent assembly 4, the firm part 162 of rotation that connects seatpillar 15 forms, the two sides in back vent assembly 4 front ends and transposition joint 161 are clamped the cooperation simultaneously, be fixed on transposition joint 161 by rotating shaft, can be along the transposition joint 161 rotating shaft be rotated, back vent assembly 4 is formed with transposition joint 161 by button bit assembly 163 and fixes, button bit assembly 163 is by locking sliding block 1631, hang fastener 1632, hang buckle 1633, governing screw consists of, locking sliding block 1631 is placed in transposition joint 161, by governing screw secured adjusted locking sliding block 1631 positions, hang to be buckled in fastener 1632 and hang buckle 1633, and with hang buckle 1633 and be fixed on transposition joint 161 by same center shaft.again by hanging fastener 1632 and hanging buckle 1633 lockings coordinating of locking sliding block 1631, thereby reach the purpose in light and handy locking upset joint, when unlocking state, only need to break into two with one's hands and lock slider 1631 along center shaft, the suspension fastener 1632 that governing screw is spacing, namely removed the locking of suspension button plate 1633 with lock slider 1631, can open suspension buckle 1633 by reversing sense this moment, remove the spacing of back vent assembly 4 and transposition joint 161, allow back vent assembly 4 can be along the transposition joint 161 rotating shaft be rotated, simultaneously be provided with the second cover safety device 164 below transposition joint 161, the second cover safety device is by miniature lever, slide block, spring forms, slide block is placed in transposition joint 161, on the miniature lever bar, cover has spring one end to be connected with slide block, the other end is placed on 161 belows, transposition joint, slide block blocks back vent assembly 4 and the clamped bottom surface that coordinates, transposition joint, with the common fixedly back vent assembly 4 of suspension buckle 1633.

Left handlebar 23 and right handlebar 24 that handlebar assembly 2 of the present utility model is mutual mirror image symmetry, each device of both sides has a handlebar deflection joint (not indicating in figure) between the right handlebar 24 of left handlebar 23 and handlebar tube I 21, handlebar can be deflected into and handlebar tube I 21 same levels along the deflection joint, when with handlebar tube I 21, handlebar tube II 22 during together with the handlebar bend forward, the right handlebar of left handlebar just is positioned at the both sides of front-wheel, has reduced to greatest extent the space after folding.

Figure 26,27 illustrates the folding step of the utility model folding bicycle:

Referring to Figure 26, with handlebar along deflection joint (indicating in figure) forward to handlebar tube I 21, car beam 1 same level after, the rotary joint 14 of pressing handlebar tube II 22 two ends with handlebar assembly 2 toward front-wheel 6 direction adjustment, include as much as possible handlebar assembly 2 in front-wheel 6 scopes, then handlebar assembly 2 is together overturn along the joint of overturning together with front fork assembly 3, make the front upper pipe of car beam 1 11 with front fork assembly 3 after front upset joint 9 upsets, front-wheel 6 and front fork assembly 3 fall in the scope that car beam 1 surrounds.

Referring to Figure 27,16 to be turned to the opposite side of car beam 1 parallel with car beam 1 along rear upset joint with trailing wheel 7, press the rotary joint 14 of saddle assembly 8, with the past trailing wheel 7 direction adjustment of saddle assembly 8, allow whole saddle assembly 8 include in as much as possible in trailing wheel 7 scopes, make integral body be smooth circular arc state, three castor 16 pulsation-frees of car beam 1 bottom contact to earth conveniently to tow simultaneously.

Of the present utility modelly step on stretcher rides except bicyclist oneself, can also ride to reduce muscle power by motorized motions, electric capacity, electrical controller that battery, saturation type self-generating device connect all can be located in car beam 1 inner chamber, battery is connected to actuating device, changes in temperature seat 81, cold and warm box 17, and the needs that GPS, LED illuminating lamp etc. various power devices satisfy the bicyclist can also be set according to specific needs.

More than open be only an embodiment of the present utility model, but the present embodiment is not limited only to this, and any those skilled in the art protect within spirit within the variation of consideration that can think of all should be considered as protection domain of the present utility model at claims.
