Nozzle Adjustment Member for Sprinkler

摘要

A nozzle adjustment member for a sprinkler is revealed. A plurality of nozzle tubes aligned in at least one row is positioned on a wall of a hollow pipe. A top end of the nozzle tube is projecting to an outside of the hollow pipe. At least one pivot support is disposed on the outside of the hollow pipe. Each pivot support is pivoted with an adjustment piece having a plurality of guiding openings. The guiding openings are positioned over the plurality of nozzle tubes correspondingly. A nozzle cover is connected with the outside of the hollow pipe for covering the adjustment piece. A plurality of long through holes for mounting the corresponding nozzle tubes is arranged at the nozzle cover. Around a pivot hole, the adjustment piece swings so as to drive the plurality of nozzle tubes moving at an angle and different water distribution patterns are provided.

主权项

1. A nozzle adjustment member for a sprinkler, comprising:
a hollow pipe disposed with at least one row of a plurality of nozzle tubes, a nozzle cover fastened and integrated with said hollow pipe and having at least one row of a plurality of long through holes positioned over said plurality of nozzle tubes and arranged on a top thereof, and two adjustment pieces each having a pivot hole disposed on one end thereof and a plurality of guiding openings extending outwardly from said pivot hole and positioned over said plurality of nozzle tubes so as to drive a displacement of said nozzle tubes, and a control part disposed on the other end thereof integrally and correspondingly, wherein a pair of shaft tubes is disposed on a middle part of said nozzle cover and mounted in said pivot holes of said adjustment pieces so as to be used as a static pivot of a swinging movement of said adjustment pieces, wherein said control part is operated such that said adjustment pieces swing and move in a pendulum-type path for synchronously driving said nozzle tubes, wherein said control part is respectively operated to separately move said two adjustment pieces, thereby driving said nozzle tubes disposed on said adjustment pieces at different angles to provide different water distribution patterns on two sides.
