It is folded.Therefore, entire stroller construction is simple, low in cost, and entire folding process is very smooth, occupied space after folding
It is small, it is easy to carry.
As shown in figure 5 and figure 7, the lower end of the back support bar 3 is provided with transverse bar 10, the articulated section 4 include with
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 figures 7 and 9, 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, the seat support 6 includes the first seat support tube 61 and can be at the first seat
Stretch the second seat support tube 62 slided in support tube 61,61 rear end of the first seat support tube and 3 lower end of back support bar
Rotation connection, 62 front end of second seat support tube and 1 upper end of foreleg are rotatablely connected.When stroller folds, second
Seat support tube 62 slides from inside to outside in the first seat support tube 61, so that seat support 6 is before and after stroller
Direction extends, so that the smooth folding of stroller.When stroller is in unfolded state, second support tube 61
Then contracting is in the first seat support tube 61, and seat support 6 is then in contraction state at this time, to guarantee the expansion shape of stroller
State.
As shown in Figure 8 and Figure 9, the seat 7 includes seat plate 71, and 71 front end of seat plate passes through front rail 11
It is connect with 62 front end of second seat support tube, 71 rear end of seat plate, which is equipped with, to be passed through and can supply for the first seat support tube 61
The sliding sleeve 72 that first seat support tube 61 slides inside, the upper end of the upper strut 9 are rotatably connected on 71 middle part of seat plate.?
When stroller folds, the first seat support tube 61 slides in sliding sleeve 72, and seat plate 71 follows second seat support tube 62 to transport
It is dynamic.
As shown in figs. 7 to 11, the projection seat body 44 protruded on front side of transverse bar 10 is additionally provided on the ontology 41, it is described
Locking device include the shell 121 being connected on projection seat body 44, being equipped in the shell 121 can longitudinally slide in it
Pulling plate 122, the pulling plate 122 are equipped with inclined angling hole 123, and being additionally provided in the shell 121 being capable of transverse movement
And the clamping block 125 engaged with the detent 124 on seat plate 71, the clamping block 125 are equipped with and communicate with angling hole 123
Clamping block can be pushed when pulling plate 122 vertically moves by being equipped in transverse holes 126, the transverse holes 126 and angling hole 123
The impeller-hub 127 of 125 transverse shiftings, being additionally provided in the shell 121 can make clamping block 125 and the detent 124 keep engaging
First spring 128.When stroller needs to fold, by pulling pulling plate 122, pulling plate 122 vertically moves in shell 121
When, the hole wall of the angling hole 123 on pulling plate 122 just pushes impeller-hub 127, and impeller-hub 127 just pushes clamping block 125 laterally to move
It is dynamic, it is just detached from the detent 124 on seat plate 71 during 125 transverse shifting of clamping block, locking device just unlocks at this time,
Stroller can start to be folded.Entire locking device is very simple, operates also very convenient.Certainly, the lock
Determine device can also using traditional locking structure, such as between two components mutually with rotation relation setting grab with
The snap-in structure of bayonet lock realizes engaging or disengaging with bayonet lock during grab rotation, so that the rotation of each component is locked,
Achieve the purpose that lock stroller.
As shown in Figure 10 and Figure 11, 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 9, the detent 124 is the detent block being arranged on seat plate 71, and in locking device locking, institute
The clamping block 125 stated is resisted against on the side of detent block.In locking device locking, clamping block 125 is resisted against the side of detent block
On face, when unlocked, the side of clamping block 125 and detent block is detached from, and 3 lower end of back support bar can be de- with 71 rear end of seat plate at this time
From and realize unlock, at this time energy baby stroller folding.
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.
