Abstract

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.

Claims

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.

2. The nozzle adjustment member for a sprinkler, as recited in claim 1, wherein a receiving space for receiving said control part is arranged at said nozzle cover.

3. A nozzle adjustment member for a sprinkler comprising:

a hollow pipe connected with and positioned over 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 long through holes positioned over said plurality of nozzle tubes and arranged on a top thereof, and

two adjustment pieces each having one row of a plurality of long through holes positioned over said plurality of nozzle tubes and assembled between said hollow pipe and said nozzle cover,

wherein two shaft tubes are positioned on a middle part between said nozzle cover and said hollow pipe, wherein a set of control parts is disposed on one end of said adjustment pieces, while opposite to said one end thereof is disposed with a pivot hole, wherein two pivot holes of said two adjustment pieces overlap with each other, wherein said control parts are operated respectively to drive said adjustment pieces swinging and moving within a pendulum-type path respectively and said correspondingly nozzle tubes are respectively controlled to be adjusted at different angles, thereby providing different water distribution patterns at different angles on two sides.

4. A nozzle adjustment member for a sprinkler comprising:

a hollow pipe in which at least one row of a plurality of nozzle tubes is disposed on an end thereof,

a nozzle cover fastened and integrated with said hollow pipe and having at least one row of long through holes positioned over said plurality of nozzle tubes correspondingly, and

two adjustment pieces, disposed between said hollow pipe and said nozzle cover, each having a pivot hole disposed on one end and a set of control parts disposed on the other end thereof, wherein a plurality of guiding openings extends outwardly from said pivot hole and is positioned over said plurality of nozzle tubes so as to drive a displacement of said nozzle tubes,

wherein a pair of shaft tubes is disposed on a middle part between said nozzle cover and said hollow pipe, wherein said shaft tubes are mounted in said pivot holes of said adjustment pieces as a static pivot of a pivoting rotation of said adjustment pieces, wherein said control part is operated in such a manner that said adjustment pieces pivot around said shaft tubes and move in a pendulum-type path respectively and for synchronously driving said nozzle tubes, thereby driving the sprinkler sprinkling at different angles to provide different water distribution patterns on two sides.
