At the bottom side of thewashbowl30′ and thefaucet body10′, and at the proper position of the washer11′ are respectively disposed a fixing hole and a thru-hole (without shown in the diagram) for the engagement of ascrew bolt12′ therewith so as to securely fix the washer11′ thereby.
• The second conventional water outlet tubing structure for faucets also has some drawbacks. Most of all, at the bottom side of thewashbowl30′ and thefaucet body10′, and at the proper position of the washer11′ are respectively provided with the fixing hole and the thru-hole to mate with thescrew bolt12′ so as to firmly secure the washer11′ onto the underside of thewashbowl30′ thereby, which is not only uneconomically time-consuming and effort-wasting in the processing thereof, but also inefficiently tedious and troublesome in the assembly thereof.
• Please refer toFIG. 4. A third water outlet tubing structure for faucets includes afaucet body10″ properly located on top of awashbowl30″ wherein at the other side wall of thewashbowl30″ is disposed a washer11″ with acoupling slot111″ defined thereon for a pair of symmetricalwater inlet pipes20″ to be guided there-through from bottom to top thereof before thewater inlet pipes20″ are further led sequentially through the bottom side of thewashbowl30″ and thefaucet body10″ and fixedly screwed up thereto. At the preset position of thewashbowl30″, at the bottom side of thefaucet body10″, and at the proper position of the washer11″ are respectively disposed a fixing hole and a thru-hole (without shown in the diagram) for the engagement of ascrew bolt12″ therewith so as to securely fix the washer11″ thereby.
• The third conventional water outlet tubing structure for faucets is also featured by some disadvantages. Most of all, at the bottom side of thefaucet body10″, at the proper position of thewashbowl30″ and at the preset position of the washer11″ are respectively disposed the fixing hole and the thru-hole to mate with thescrew bolt12″ so as to secure the washer11″ firmly onto the underside of thewashbowl30″, which is not only uneconomically time-consuming and effort-wasting in the processing, but also inefficiently tedious and troublesome in the assembly thereof.
