Abstract
A cross stay folding mechanism for child trolley comprises a first linkage and a second linkage which are arranged at two sides of a frame of a pushchair, and a first cross stay and a second cross stay whose outer ends are rotatablely connected to the first linkage and the second linkage. The inner end of the first cross stay and the inner end of the second cross stay are rotatablely connected by a third rotary shaft. A first angular sliding piece and a second angular sliding piece are slidingly arranged on the first linkage and the second linkage. A first sliding chute is opened on either the first angular sliding piece or the first cross stay whilea first guide pin is arranged on the other. The first guide pin is slidingly inserted in the first sliding chute. A second sliding chute is opened on either the second angular sliding piece or the second cross stay while a second guide pin is arranged on the other. The second guide pin is slidingly inserted in the second sliding chute. When the first angular sliding piece and the second angular sliding piece are pulled upwards, the first cross stay and the second cross stay can move upwards at the same time so as to be folded. The utility model has less connecting linkages, and consequently reduces production cost.
