Faucet assembly and a bushing thereof
A faucet assembly and a bushing thereof are described. The faucet assembly comprises a case, a drain tube and a bushing. The drain tube is assembled in the case. The drain tube has a first opening and a second opening extending coaxially from the first opening. The bushing set is at the first opening of the drain tube. The bushing is assembled to a water pipe extending from a wall. The case has an exit at a front end thereof. The second opening of the drain tube is connected to the exit. The bushing comprises a main body. The main body has a through opening formed therethrough to be assembled to a water pipe. The main body further comprises a water-inlet portion, a water-outlet portion, and a protruding portion between the water-inlet portion and the water-outlet portion. The protruding portion is thicker than both of the water-inlet portion and the water-outlet portion of the main body. The water-outlet portion has an outer surface and an inner surface.
1. A bushing set at a drain tube having a first opening and a second opening extending coaxially from the first opening, the bushing comprising:
a main body having a through opening formed therethrough to be assembled to a water pipe, the main body comprising a water-inlet portion, a water-outlet portion, and a protruding portion between the water-inlet portion and the water-outlet portion;
the protruding portion being thicker than both of the water-inlet portion and the water-outlet portion of the main body;
the water-outlet portion having an outer surface and an inner surface; and
a step portion being defined between the first opening and the second opening of the drain tube, wherein the water-outlet portion of the main body is adjacent to the step portion.
2. The bushing of claim 1 , further comprising a first slope between the water-inlet portion and the protruding portion.
3. The bushing of claim 1 , further comprising a second slope between the water-outlet portion and the protruding portion.
4. The bushing of claim 1 , further comprising a first ring groove formed in the outer surface of the water-outlet portion.
5. The bushing of claim 4 , further comprising a first ring member positioned in the first ring groove.
6. The bushing of claim 1 , further comprising a second ring groove formed in the inner surface of the water-outlet portion.
7. The bushing of claim 6 , further comprising a second ring member positioned in the second ring groove.
8. The bushing of claim 1 , wherein the busing is set at the first opening of the drain tube.
9. The bushing of claim 1 , wherein the first opening is larger in diameter that the second opening of the drain tube.
10. The bushing of claim 1 , wherein the first opening has an inner side adjacent to the step portion.
11. The bushing of claim 10 , wherein the first ring member is adjacent to the inner side of the first opening.
12. A faucet assembly comprising:
a case, a drain tube and a bushing, the drain tube assembled in the case, the drain tube having a first opening and a second opening extending coaxially from the first opening, the bushing set at the first opening of the drain tube, the bushing assembled to a water pipe extending from a wall, the case having an exit at a front end thereof, the second opening of the drain tube connected to the exit,
wherein, the bushing comprises:
a main body having a through opening formed therethrough to be assembled to a water pipe, the main body comprising a water-inlet portion, a water-outlet portion, and a protruding portion between the water-inlet portion and the water-outlet portion;
the protruding portion being thicker than both of the water inlet portion and the water-outlet portion of the main body;
the water-outlet portion having an outer surface and an inner surface; and
a step portion being defined between the first opening and the second opening of the drain tube, wherein the water-outlet portion of the main body is adjacent to the step portion.
13. The faucet assembly of claim 12 , further comprising a threaded hole formed on the water-inlet portion of the main body.
14. The faucet assembly of claim 12 , wherein the water-outlet portion and the water-inlet portion have the same thickness.
15. The faucet assembly of claim 12 , wherein the protruding portion is thicker than both of the water-inlet portion and the water-outlet portion of about 3.6 mm.
16. The faucet assembly of claim 12 , further comprising a knob being movable to control an on-off state of the drain tube.
