Abstract:
1. An adjustable sprinkler, comprising: a base having a vertical water way, and a transverse through hole formed at an upper end of said vertical water way; a transverse axle tube having an axial transverse water way formed therein, wherein said transverse water way has an open end connected to said transverse through hole of said base, wherein said transverse axle tube further has at least one water outlet formed to a peripheral of said transverse axle tube and is communicated with said transverse water way; a mobile tube, having: an axial water way formed therein; a water outlet communicated with said axial water way; a transverse axial hole formed on said mobile tube at a position adjacent to said water outlet and has an axial direction perpendicular to that of said axial water way, wherein said transverse axial hole is arranged to connect to said transverse axle tube, and has a plurality of protrusions formed on an inner wall of said transverse axle hole for selectively blocking said water outlet of said transverse axle tube; and an extension portion downwardly extended from said axial water way such that a center of gravity of said mobile tube is close to said extension portion while said transverse axle hole is regarded as a pivot; and an nozzle mounted to said water outlet of said mobile tube, in such a manner that when said protrusions of said transverse axle hole are moved away from said water outlets of said transverse axle tube so that said water outlets are not blocked by said protrusions, said water way of said mobile tube forms an angle of elevation such that water coming from said vertical water way of said base is arranged to first flow into said transverse water way of said transverse axle tube, and then into said transverse axle hole of said mobile tube through said water outlets of said transverse water way, and finally be sprinkled out of said water outlet through said water way of said mobile tube, wherein when said mobile tube is pivoted on said transverse axle tube, said angle of elevation of said mobile tube is arranged to decrease so that said protrusions are moved to block said water outlets so as to selectively adjust a flow rate of said water.
