Abstract
The utility model discloses a baby carriage convenient to fold. The baby carriage convenient to fold comprises folding joints. The folding joints include a lower joint and an upper joint which are hinged through a rotary shaft. The lower joint is provided with an arc slide way distributed around the rotary shaft. A bent locking slide way is joined with the end of the arc slide way. A slide block with a pulling cable is installed in the upper joint. The slide block is provided with a clamping pin extending into the arc slide way. The upper joint is further internally provided with a spring used for pushing the clamping pin into the locking slide way. As the arc slide way of which the end is joined with the locking slide way is matched with the slide block which is arranged in the upper joint and provided with the pulling cable and the clamping pin, the joints can be unfolded and folded.
