The invention discloses a pulley locking device of an air cooler. Hollow shafts are arranged on a base, bearings are fixed to the hollow shafts, pulley supports are fixed to the bearings, pulleys are fixed to the pulley supports, and the hollow shafts are sleeved with locking sleeves and connected to the upper portions of the bearings in a sleeving mode. A switch support is arranged in a shell, the bottom ends of driving rods of the switch support penetrate through the hollow shafts to extend into the pulley supports, rotating bearings are fixed to the switch support, locking pieces are arranged on the two sides of the pulleys, and the upper ends of the locking pieces penetrate through one sides of the pulley supports to be connected with the rotating bearings. Multiple clamping grooves and a clamping block are arranged on each pulley, locking blocks matched with the clamping grooves are arranged on the locking pieces and provided with grooves matched with the clamping blocks, an operation rod is arranged on the switch support, a switch button assembly is arranged at the top inside the shell, and the top end of the operation rod extends out of the shell. The pulley locking device of the air cooler locks the pulleys more conveniently and rapidly, and the practicability and using effect of the air cooler are improved.
