Wheel set brake mechanism and baby transport

A wheel set brake mechanism for locking a wheel of a movable frame, the wheel having a wheel stand, the wheel stand being mounted on the movable frame through a hollow shaft in such a way the wheel is rotatable in all directions, the wheel set brake mechanism comprising:

• a drive member mounted on the movable frame;
• and
• a brake assembly including a drive pin, a traction member and a locking member, wherein the drive pin is operably connected to the drive member, the traction member includes a first cable and a second cable, a first end of the first cable is connected to the drive pin, a second end of the first cable extends into an inner cavity of the hollow shaft to be rotatably connected to a first end of the second cable, and a second end of the second cable is connected to the locking member;
• wherein the drive member is configured to drive the drive pin to slide so that the traction member causes the locking member to slide to lock the wheel, and
• wherein the locking member includes a transverse shaft and a longitudinal shaft arranged perpendicularly to each other, the longitudinal shaft is slidably engaged with the wheel stand, an axis of the longitudinal shaft is perpendicular to a rolling axis of the wheel, the second end of the second cable is connected to the longitudinal shaft.
