Abstract

A top connecting mechanism of a canopy includes a connecting seat and a plurality of connecting rods. The connecting seat includes a plurality of pivoting grooves, each of which includes a first side wall and a second side wall. Each of the plurality of pivoting grooves includes an elastic buckling column and an abutting portion. The elastic buckling column includes a buckling protrusion. Each of the plurality of connecting rods is configured to be rotated relative to the connecting seat to be in a first position, and a bottom of each of the plurality of connecting rods is configured be supported on the abutting portion. The buckling protrusion is configured to be buckled to a top of a corresponding one of the plurality of connecting rods, and the abutting portion and the buckling protrusion cooperate to maintain the corresponding one of the plurality of connecting rods in the first position.
