Abstract
This utility model provides a novel cushion adjustment mechanism and child tricycle, which includes cushion; one end of the said main beam tube is connected with the cushion and the other end is connected with the tricycle body; the adjustment unit is fixing-connected with the main beam tube. The adjustment unit is provided with a positioning assembly; the rear part includes two fixing plates. One end of the fixing plates is connected with the rear wheel and the other end is connected with the adjustment unit. The fixing plate connected with the adjustment unit is provided with a counter locking screw rod. One end of the counter locking screw rod passes through the rotation hole and is fixing-connected with the adjustment unit. After adjustment, the child tricycle using this mechanism will have a good stability and avoids the slippage issue of the cushion height controlled by the friction force.
