Specific embodiment
Below with reference to Fig. 1 to Fig. 3, the utility model is described further:
As shown in Figure 1, a kind of piston type step-less adjustment supporting leg, including outer support pipe 4 and inner support tube 6, outer support pipe
4 by supporting foot pad 1 to abut with automobile chassis, and inner support tube 6 is connect with children car seat, inner support tube 6 and outer support pipe 4
It connects and can mutually stretch, between inner support tube 6 and outer support pipe 4 between the two by piston sealing structure step-less adjustment
Collapsing length.
Piston sealing structure includes upper sealing structure and lower sealing structure；Upper sealing structure be located at 6 lower end of inner support tube with
The junction of 4 upper end of outer support pipe, lower sealing structure are located at 4 lower end of outer support pipe and support the junction of foot pad 1.Upper sealing knot
Structure includes piston 7, and piston 7 is fixed on 6 lower end of inner support tube, and the inner wall of piston 7 and outer support pipe 4 coincide and is in seal shape
State.It is additionally provided with supporting sleeve 5 in outer 4 upper end inner wall of support tube, supporting sleeve 5 is used to support the movement of inner support tube 6.
Lower sealing structure includes support tube socket 3, and support 3 lower end of tube socket is connect with support foot pad 1 and the two can be opposite
Displacement, support 3 upper end of tube socket are groove, are sealed in 4 lower end of outer support pipe insertion groove, the bottom of groove is equipped with gas vent, right
Column 8 is equipped in support foot pad 1 with answering, and the thin lower end in 8 upper end of column is thick and lower end is fixedly connected with support foot pad 1, column 8
