Abstract

The utility model relates to a connecting rod connecting device for baby carriages, which is composed of a rotating element, a plug, an elastic element, a slide block and a traction element. In the utility model, one end of the elastic element is fixed on the rotating element, and the other end of the elastic element pushes and supports the plug and is used for pushing the plug in a through hole of a first connecting rod. When the utility model has a need for being retracted and folded, a control switch is pressed and pulls the slide block to move upwards by the traction element. Because the end of the plug is provided with a lead angle, the plug is retracted along a bevel of the slide block causing the rotating element to move in the axial direction of the first connecting rod, the first connecting rod and a second connecting rod are gradually closed, and retracting and folding actions are completed. Because the utility model has a simpler structure compared with a connecting device of a folio joint design, the utility model has the advantages of low cost and less failure.
