Abstract
The invention discloses a folding baby carriage frame. The folding baby carriage frame comprises a front frame pipe, a rear frame pipe and an armrest pipe and is characterized in that the folding baby carriage frame further comprises a first connecting piece, a second connecting piece, a linkage piece and a first folding control device. The first folding control device is used for locking and fixing the first connecting piece and the second connecting piece when the baby carriage frame is spread to be used. When the baby carriage frame is folded and collected, the first connecting piece and the second connecting piece are unlocked so that the armrest pipe can freely rotate around a first hinging part relative to the front frame pipe and be folded and collected and the rear frame pipe can be driven by the linkage piece to freely rotate around a second hinging part relative to the front frame pipe. The folding baby carriage frame is simple in structure and convenient to collect.
