Embodiment：
As depicted in figs. 1 and 2, a kind of technical solution of present invention offer, a kind of braking mechanism of Medical flat stroller,
Including stroller chassis 1, universal wheel 8 and braking mechanism 2, and the braking mechanism 2 is arranged on stroller chassis 1, institute by threaded post 3
The bottom for stating braking mechanism 2 is fixed with universal wheel 8 by axle, it is characterised in that：The braking mechanism 2 includes shell 201, institute
Surface is provided with U-shaped loose slot 203 after stating shell 201, and lever shaft 204 is provided among the inner top of shell 201, and described
The wheel that Z-type is movably fixed with lever shaft 204 steps on 202, and the left side of shell 201 is internal to be provided with limited block 205, described spacing
Block 205 has extended transversely through guide rail 206, and the bosom of guide rail 206 installs hinged ball 207, and the wheel steps on 202 one end and passes through ball pivot
It is longitudinally connected in hinged ball 207, the hinged ball 207 is laterally fixedly connected with brake pad 208, and the hinged ball 207 passes through horizontal ball
Hinge is connected to connecting shaft expansion link 6, and the connecting shaft expansion link 6 is horizontally through loose slot 203 and is connected with square foot-operated circle 7, and institute
State and Hanging frame 4 is connected with by movable axis among connection expansion link 6, the top of Hanging frame 4 is fixed on the bottom of stroller chassis 1
Portion.
Preferably, the threaded post 3 and the junction of braking mechanism 2 are provided with driving washer 5, and the driving washer 5
It is flexibly connected with braking mechanism 2；The guide rail 206 is into runway shape；The universal wheel 8 and braking mechanism are in the bottom of stroller chassis 1
It is symmetrical arranged, and 7 left ends of the foot-operated circle connect a braking mechanism again by connecting shaft expansion link 6；The brake pad 208 is set
The rubber friction pad of steel plate and arcuation is equipped with, and the radian of the rubber friction pad is identical with the surface radian of universal wheel 8, rubber
