Abstract

An adjustable water-guiding rod for a cleaning brush comprises a rotary joint furnished between a water-input rod and a water-output rod. The rotary joint includes two disks, each of which is mounted on one end of the water-input rod and the water-output rod respectively. The disks are furnished with ring-shaped water passages respectively in communication with each other. The inner surface and the outer surface of the ring-shaped water passage are mounted with seal rings. One of the two disks is furnished with clutch teeth and a bolt at the center thereof. The other disk is mounted with a positioning disk and a spring is provided therebetween. The positioning disk has clutch teeth for engaging with the clutch teeth of one of the disks. A rotary disk having a thread center hole is mounted on the outer surface of the positioning disk to couple with the bolt for joining the two disks and the positioning disk together. The two disks are set at a position by the clutch teeth. After the rotary disk is loosened, the spring will push the positioning disk out of the engagement of the clutch teeth gradually. The two disks are still maintained in the original tension to let the water-output rod be adjusted at a desired angle without water leakage.

Claims

1. An adjustable water-guiding rod for a cleaning brush comprising:

a water-input rod including a water-input passage in center thereof;

one end of said rod having a disk furnished with a ring-shaped water passage in communication with a said water-input passage;

both inner and outer surfaces of said ring-shaped water passage furnished with ring-shaped grooves for receiving seal rings respectively;

the center of said disk furnished with a bolt, and the outer edge of said disk furnished clutch teeth;

a surface of said disk assembled together with a water-output rod;

said bolt molded together with said water-input rod disk;

the outer end of said bolt furnished with a thread portion for mounting a rotary joint thereon;

said water-output rod having a water-output passage in center thereof;

one end thereof having a disk furnished with a ring-shaped water passage in communication with a water-output passage;

both inner and outer surfaces of said ring-shaped water passage of said disk furnished with ring-shaped grooves respectively for receiving seal rings;

the center of said disk furnished with a cylindrical hole for receiving said bolt, and the outer edge of said disk mounted with a positioning disk;

two sealing rings having different diameters mounted between said disks of said water-input rod and said water-output rod respectively

a spring mounted in a cylindrical groove of said disk of said water-output rod, and one end of said spring pushing against the inner surface of said positioning disk;

said positioning disk mounted over said disk of said water-output rod by means of a cylindrical space which being similar to outer shape of said disk;

one side of said positioning disk furnished with a cut-out for receiving said water-output rod;

the center of said positioning disk having a round hole for receiving said bolt;

the outer edge of said positioning disk furnished with ring-shaped clutch teeth engaged with said clutch teeth of said disk of said water-input rod; and

a rotary disk having a cross-shaped knob on the outer surface thereof, and the center thereof furnished with a threaded hole;

the inner surface thereof furnished with slightly salient rib strips;

said threaded hole engaged with said thread portion of said bolt so as to control tension between said water-input rod and said water-output rod.

2. An adjustable water-guiding rod for a cleaning brush as claimed in claim 1, wherein the outer edge of said disk on one end of said water-input rod is furnished with said clutch teeth to be engaged with said clutch teeth on the outer edge of said positioning disk over said disk of said water-output rod.

3. An adjustable water-guiding rod for a cleaning brush as claimed in claim 1, wherein the outer edge of said disk of said water-input rod is furnished with ring-shaped clutch teeth slightly higher than inner surface thereof;

a said ring-shaped surface furnished within said clutch teeth so as to receive a round flange of disk of said water-output rod;

after said ring-shaped surface and said round flange being engaged together, a circular guide surface being formed for said two disks.

4. An adjustable water-guiding rod for a cleaning brush comprising:

a water-input rod having a water-input passage in center thereof, and one end of said rod furnished with a disk, which has a ring-shaped water passage in communication with said water-input passage;

the inner and outer surfaces of said ring-shaped water passage furnished with ring-shaped grooves for receiving seal rings respectively, and the center of said disk having a bolt;

a said bolt furnished integrally on said disk upon molding;

the outer end of said bolt having a thread portion for mounting a rotary joint;

a water-output rod having a water-output passage in the center thereof, and one end of said rod furnished with a disk, which has a ring-shaped water passage in communication with said water-output passage;

the inner and outer surfaces of said ring-shaped water passage furnished with ring-shaped grooves for receiving seal rings respectively;

the center of said disk furnished with a cylindrical hole for receiving said bolt;

a rotary disk having a threaded hole in center thereof to be mounted on the thread portion of said bolt; and

which characterized that the outer edge of said water-input rod disk being furnished with clutch teeth, of which the inner edge having a ring-shaped groove for receiving a round flange of said disk of said water-output rod;

said two disks able to be assembled together by means of said ring-shaped surface and said round flange;

the center of said disk of said water-output rod having a cylindrical groove for receiving a spring to be pressed in said cylindrical groove by means of said rotary disk;
