Embodiment
The present invention is specifically described with reference to specific embodiment.
Embodiment：As shown in Figures 1 to 8, bassinet wheel automatic retracting structure, including handle pipe 1, lower coil pipe 2, front-wheel 3,
Trailing wheel 4.Handle pipe 1 is hinged with lower coil pipe 2, in this example, and handle pipe 1 and the front end of lower coil pipe 2 are hinged.Front-wheel 3 is located at front-wheel seat
On 301, trailing wheel 4 is on rear wheel seat 401, and front-wheel seat 301 can be rotatably connected with lower coil pipe 2 around lower coil pipe 2, rear wheel seat 401
It can be rotatably connected with lower coil pipe 2 around lower coil pipe 2.Lower coil pipe 2 provided with can along lower coil pipe 2 slide sliding sleeve 5, handle pipe 1 with
Connecting rod 6, the one end of connecting rod 6 and the movable connection of handle pipe 1, the other end of connecting rod 6 and the movable company of sliding sleeve 5 are provided between lower coil pipe 2
Connect.Lower coil pipe 2 is provided with interlinked mechanism, and when being folded between handle pipe 1 and lower coil pipe 2, sliding sleeve 5 drives front-wheel by interlinked mechanism
Seat 301, rear wheel seat 401 make front-wheel 3, trailing wheel 4 from placing vertically to horizontal positioned directional steering.
