Abstract
The utility model relates to a baby carriage, in particular to an improved framework of the baby carriage which is a herringbone carriage support formed by the combination of a front-wheel rod, a rear-wheel rod, a seat rod, a lying-back support, a connecting seat, a positioning seat, a carriage-pushing rod and the like. The top of the front-wheel rod of the utility model and the connecting seat are positioned by fixed sleeves, and the top end of the rear-wheel rod and the connecting seat are in pivot connection. The seat rod crossed between the lower end of the carriage-pushing rod and the lower section of the rear-wheel rod, and the middle section of the seat rod and the lower end of the lying-back support are in pivot combination. The carriage-pushing rod sequentially passes through through-holes for the carriage-pushing rod arranged on the connecting seat and the positioning seat from the bottom up. In the course of carriage folding and extension, the carriage-pushing rod enables the distance of up-down shifting position to be firmly fixed with the through-holes for the carriage-pushing rod arranged on the connecting seat and the positioning seat as a track. The external portion of the upper section of the carriage-pushing rod is fixedly sleeved with a clamping pull member. Further, the inner of carriage-pushing rod is sequentially provided with an upper-pulling board, a lower-pulling board, a tensioning member, a fixed element and a stopping member. The interlocking of the stopping member by the clamping pull member releases the fixed clamping connection of the carriage-pushing rod and the positioning seat, thereby achieving the effect of folding the carriage body.
