The beneficial effects of the utility model are:Infant car seat elevating mechanism described in the utility model is stepped on described in utilizing Plate controls ratchet assembly, and ratchet assembly drives the screw rod to rotate by gear-driven assembly, realizes the lifting of connection pedestal, makes Directly foot pedals can complete the adjustment of height of seat to user repeatedly in operation, can be made with being observed in adjustment With conveniently, structure design is relatively simple, safety.
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 Guiding rib 14 can be arranged in the inner wall of the package assembly 11 in rotation in part 11, and the periphery of connection pedestal 10 is led described in correspondence Guide groove 15 is set to the position of muscle 14;In addition to this it is possible to the section of the inner cavity of the package assembly 11 is designed as ellipse Circle, the section for connecting the periphery of pedestal 10 are ellipse with matching;Alternatively, can also will be in the package assembly 11 The section of chamber is designed as rectangle, and the section for connecting the periphery of pedestal 10 is designed as rectangle with matching;Or it will be described The section of the inner cavity of package assembly 11 is designed as equilateral triangle, and the section for connecting the periphery of pedestal 10 is with matching equilateral Triangle.Above several forms can realize that connection pedestal 10 cannot the rotation in package assembly 11.
When actually doing exercises, adjustment height of seat tends not to complete by trampling a pedal 13, ordinary circumstance It is required for repeatedly trampling.Therefore, 1 reduction torsion spring 16 can be additionally provided in the support base, one end of reduction torsion spring 16 is fixed On support base 1, the other end of reduction torsion spring 16 is fixed on pedal 13.In this way, reduction torsion spring 16 is just after the completion of once trampling It can be resetted with the pedal 13, so that next time tramples, without manually adjusting.
Preferably, in order to improve safety in utilization, it is also equipped with bolt on the support base 1, confession is offered on pedal 13 The interspersed jack of bolt.After seat adjustment is completed child being put into perambulator, user can be by bolt by the pedal 13 fix, and prevent that baby's height is made to change because accidentally stepping on.
The action process of infant car seat elevating mechanism described in the utility model is:User operate pawl 2 with it is two-way The pawl 2 of 3 side of ratchet abuts against, and bolt is extracted from the jack of pedal 13, repeatedly pushes pedals 13, and pedal 13 drives institute It states the rotation of fixed disk 12 or forward or reverse is determined by the force direction of pedal(It is the prior art herein, the utility model does not have Improvement is made, is repeated no more).Fixed disk 12 drives bidirectional ratchet 3 to rotate by the driving shaft 4.Bidirectional ratchet 3 passes through gear Transmission component drives the screw rod 8 to rotate, and nut drives the fixed disk 12 to move up and down the adjustment for completing seat.
