Aforesaid a kind of buffer braking device that is used for perambulator is characterized in that described space cam one end face is provided with deep-slotted chip breaker, is provided with cam profile in deep-slotted chip breaker, and cam profile is provided with the recessed brake position and the un-brake position of epirelief.
Aforesaid a kind of buffer braking device that is used for perambulator, it is characterized in that described cam chair is provided with the jack that connects along the main-shaft axis direction, on the jack hole wall, be provided with along the dovetail furrow of main-shaft axis direction, the deep-slotted chip breaker notch one end outer rim of space cam is provided with step, the space cam outer wall is provided with coattail strip, and coattail strip cooperates in the insertion dovetail furrow.
Aforesaid a kind of buffer braking device that is used for perambulator, it is characterized in that being connected by pin between described brake lever and the pull bar, brake lever and pull bar bonded assembly one end are provided with step, and step withstands the buffering operating spring, and the other end of buffering operating spring withstands on the cam chair.
Compared with prior art, the utility model has following advantage:
1, the utility model is provided with the buffering operating spring in brake gear, can when needing brake
In time step on brake pedal, can realize timely brake, safe and reliable;
2, the utility model adopts cam mechanism to drive brake lever, and is simple in structure, easy to operate.
