The ontology 41 that transverse bar 10 is fixedly connected, the ontology 41 is equipped with to the preceding convex body 42 protruded on front side of transverse bar 10, described
2 upper end of back leg be hinged on before on convex body 42, the lower convex body 43 protruded below transverse bar 10 is additionally provided on the ontology 41,
8 upper end of draw bar is hinged on lower convex body 43.Therefore, back leg 2, back support bar 3 and draw bar 8 are not coaxial hinged,
But be arranged in a staggered manner, back leg 2 and articulated section 4 position that is hinged are located at the front side of 3 lower end of back support bar, draw bar 8 and articulated section 4
Articulated position is located at the lower end of articulated section 4 so that baby stroller fold up it is smooth flexibly.
As shown in Figure 7 and Figure 8, the articulated section 4 is located at the inside of back support bar 3, and the lower convex body 43 is located at lordosis
The inside of body 42, total is simple and compact, so that baby stroller volume after folding is small, folds flexibly.
As shown in Fig. 1, Fig. 8, Fig. 9 and Figure 10, seat board 11, the ontology 41 are fixedly connected on the mounting bar 6
On be additionally provided with the projection seat body 44 protruded on front side of transverse bar 10, the locking device includes the shell being connected on projection seat body 44
121, the shell 121 is interior to be equipped with the pulling plate 122 that can longitudinally slide in it, and the pulling plate 122 inclines equipped with inclined
Inclined hole 123, being additionally provided in the shell 121 being capable of transverse movement and the clamping block that engages with the detent 124 on seat board 11
125, the clamping block 125 is equipped with the transverse holes 126 communicated with angling hole 123, the transverse holes 126 and angling hole
The impeller-hub 127 that 125 transverse shifting of clamping block can be pushed when pulling plate 122 vertically moves, the shell are equipped in 123
Being additionally provided in 121 can make clamping block 125 keep the first spring 128 engaged with detent 124.It needs to fold in baby stroller
When, by pulling pulling plate 122, when pulling plate 122 vertically moves in shell 121, the hole wall of the angling hole 123 on pulling plate 122 is just
Push impeller-hub 127, impeller-hub 127 just pushes 125 transverse shifting of clamping block, during 125 transverse shifting of clamping block just with
Detent 124 on seat board 11 is detached from, and the lower end of back support bar 3 can start the movement being located remotely from each other with 11 rear end of seat board at this time, this
When locking device just unlock, baby stroller can start to be folded.Certainly, the locking device can also be using tradition
Locking structure, such as mutually with rotation relation two components between be arranged grab and bayonet lock snap-in structure, in card
Hook realizes that engaging or disengaging with bayonet lock reach locking baby stroller to lock the rotation of each component during rotating
Purpose.
As shown in figure 8, the detent 124 is the detent block being arranged on seat board 11, it is described in locking device locking
Clamping block 125 be resisted against on the side of detent block.In locking device locking, clamping block 125 is resisted against the side of detent block
On, when unlocked, the side of clamping block 125 and detent block is detached from, and 3 lower end of back support bar can be detached from simultaneously with 11 rear end of seat board at this time
It is separate, it can be achieved with the folding of baby stroller.
As shown in Figure 9 and Figure 10, being also connected on the shell 121 can stop pulling plate 122 to vertically move and opposite
Two locks that can be stepped down after 121 transverse shifting of shell for the longitudinal movement of pulling plate 122 push button 129, also set in the shell 121
There is the second spring 120 that can push two locks that button 129 is pushed to reset.After pushing two lock pushing buttons 129, ability stretchy is drawn
Plate 122 vertically moves, and otherwise pulling plate 122 pushes button 129 to stop by two locks.Therefore, two locks push the setting of buttons 129 can be with
The malfunction for preventing pulling plate 122 avoids locking device from misreading lock, more ensures safety.
As shown in Figure 1,3 upper end of back support bar is also rotatably connected to handspike 13.Certainly, handspike 13 can also be slided
It is arranged in back support bar 3 dynamicly.The setting of handspike 13 can be convenient user and push baby stroller.
