Abstract

A sprinkler rotary mechanism and a sprinkler are provided. The rotary mechanism comprises a bracket and a reversing carrier, with the latter disposed on the rotation shaft of the bracket. A transmission shaft is disposed on the reversing carrier so as to drive the bracket. The sprinkler comprises a tube, a gasket, an adaptor, an angle carriage, the rotary mechanism, a reversing mechanism, a sprinkler head tube, and a nozzle. The reversing mechanism is rotated to strike the rotary mechanism, and in turn activate the sprinkler head tube to rotate. The water stream sprayed out of the nozzle impacts the reversing mechanism at the other side, and so repeated in order to achieve the rotation of the sprinkler. The present sprinkler uses mechanical transition to replace spring deformation used in the prior art to achieve water stream rotation. The sprinkler is resistant to damage and has simpler structure and larger cover range.
