Preferably, described sleeve is provided with axial groove, sets and the depression bar of drive block circumferential clocking of turbine in rotary handle, and described depression bar has the circumferential positive stop strip coordinated with axial groove。
In this utility model, the circumferential positive stop strip of depression bar can snap in the axial groove in sleeve, keeps rotary handle circumferentially fixed, and namely depression bar coordinates composition two road locking devices with sleeve。
Preferably, setting the spring supporting described depression bar in described rotary handle, drive block has the stopper slot adapting to the slip of described depression bar。
Depression bar is had thrust by spring, depression bar is kept to coordinate rotary handle is locked with sleeve, the active force of spring is overcome by moulded rod, circumference positive stop strip is made to exit in axial groove, i.e. rotatable rotary handle, and driving drive block to circumferentially rotate by depression bar, the stopper slot on drive block is for adapting to the axial movable of depression bar。
Preferably, described expansion link is two, is plugged in the two ends of assembling pipe respectively, and is provided with stage clip between two expansion links。
The both sides of rear wheel support are provided with lock sleeve, and two expansion links can simultaneously enter locking slot with fixing hand push frame and rear wheel support, rotates rotary handle, can simultaneously drive two expansion links and mutually draw close, and exit locking slot, to unlock handbarrow and rear wheel support。
This utility model simple in construction, easy to operate, hand push frame and the rear wheel support cooperation by locking device, keep vehicle frame stably to launch after locking, fold for vehicle frame after unblock。

Detailed description of the invention
Below in conjunction with accompanying drawing, baby stroller of the present utility model is described in further detail。
As Figure 1-4, a kind of baby stroller being easy to folding and unfolding, including vehicle frame and seat, vehicle frame includes front-wheel support 302, rear wheel support 301, arm-rest frame 304, hand push frame 303 and bracing frame 306。Hand push frame 303 and rear wheel support 301 connect by controlling vehicle frame expansion and the locking device 310 folded, and locking device includes:
Being fixed on the lock sleeve (not shown) of rear wheel support 301 both sides, this lock sleeve is provided with locking slot；
It is rotatably assorted at hand push frame 303 end the expansion link 315 that coordinates with locking slot；
And it is axially movable to exit rotary handle 313 and the turnbarrel 314 of locking slot for driving expansion link 315。
Locking device 310 also includes the assembling pipe 316 being fixed on hand push frame 303, and the end of bracing frame 306 is slidingly connected the joint 311 for the pipe 316 that is linked and packed, and assembling pipe 316 is by the bottom-hinged of movable pull bar 312 with rear wheel support 301。
Expansion link 315 is two, being plugged in the two ends of assembling pipe 316 respectively, and be provided with stage clip 321 between two expansion links 315, two expansion links 315 can simultaneously enter locking slot with fixing hand push frame and rear wheel support, expansion link 315 is had resiliency supported by stage clip 321, keeps expansion link 315 to insert in tight groove。
