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 long through holes positioned over said plurality of nozzle tubes and arranged on a top thereof;

a shaft tube disposed on a middle part of said nozzle cover; and

a single piece 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 said single piece has a pivot hole disposed on a middle part thereof and a set of control parts disposed on two ends thereof, wherein said pivot hole is positioned over said shaft tube as a pivot such that said control part is operated to drive two ends of said single piece to swing in a pendulum-type path and said plurality of nozzle tubes is adjusted at different angles respectively, thereby providing different water distribution patterns at different angles on two sides, wherein said single piece comprises two adjustment pieces, wherein each of said adjustment pieces has a pivot hole and said pivot holes of said adjustment pieces are overlapped and integrated to define said pivot hole of said single piece, so as to enable said single piece to swing at reverse direction through said pivot.

2. The nozzle adjustment member for a sprinkler, as recited in claim 1, wherein said through holes of said single piece are respectively arranged in said adjustment pieces, wherein said through holes arranged in different adjustment pieces are equal in height.

3. The nozzle adjustment member for a sprinkler, as recited in claim 1, wherein said hollow pipe is disposed with a plurality of holes that are aligned and spaced at an interval and said plurality of nozzle tubes project from said plurality of holes to an outside of said hollow pipe correspondingly, wherein said hollow pipe is arranged with a plurality of racks equal in height for supporting said adjustment pieces stably.

4. The nozzle adjustment member for a sprinkler, as recited in claim 1, wherein said set of control parts comprises two control parts and each of said control parts is disposed on one end of said adjustment member.
