Description of the drawings
Attached drawing 1 is the structural schematic diagram of infant car seat elevating mechanism described in the utility model.
Specific implementation mode
A preferred embodiment of infant car seat elevating mechanism described in the utility model is shown refering to attached drawing 1.Such as
Figure, infant car seat elevating mechanism described in the utility model, including a support base 1, are arranged the spine in the support base 1
Wheel assembly and gear-driven assembly, the ratchet assembly include one can commutate be rotatably installed on the support base 1
Pawl 2, one is supported on support with 2 matched bidirectional ratchet 3 of the pawl, the bidirectional ratchet 3 by a driving shaft 4
In seat 1, the gear-driven assembly includes one and is mounted on the active oblique gear 5 that is rotated with bidirectional ratchet 3 on driving shaft 4, and one
A driven helical gear 6 being meshed with active oblique gear 5,6 center of driven helical gear is equipped with to be synchronized with driven helical gear 6
The support base 1 is stretched out in the upper end of the power output shaft 7 of rotation, the power output shaft 7, and the upper end of power output shaft 7 is one
A screw rod 8, screw rod 8 screw togather be equipped with adjusting nut 9 outside, and the periphery of adjusting nut 9 is installed with to be moved down on adjusting nut 9
Dynamic connection pedestal 10.The connection pedestal 10 is used to install the vehicle seat of perambulator.1 top of support base is installed with package assembly
11, the setting that the connection pedestal 10 slides up and down cannot rotate, the driving shaft in package assembly 11 in package assembly 11
Fixed disk 12 is installed, the pedal 13 that the bidirectional ratchet 3 rotates can be driven by fixing eccentric being equipped on disk 12 on 4.
In actual implementation, in order to enable the connection pedestal 10 to be slided up and down in package assembly 11, but cannot be in housing
