Description
- The present invention relates to a faucet, and more particularly to a bendable positioning structure of an outlet pipe for the faucet.
- A faucet is one of the indispensable water supply tools in human life, and the development of the faucet has also contributed to the progress of human beings in the application of “washing methods”. Different structural designs of faucets are used for washing to provide consumers with diversified styles. Because these faucets are designed for specific purposes, it is more convenient for people to use water.
- Conventionally, the faucets installed on the sink are mostly designed in a vertical type. For the convenience of water control, a water control valve is set on the side of a body of a faucet, and an outlet pipe is fixed on a top of the body. However, this faucet is applied to clean a countertop, but a water supply range of the outlet pipe cannot cover the entire countertop, so an internally-connected faucet has been developed, wherein the outlet pipe has a flexible connection tube received therein, an end of the flexible connection tube is connected with a threaded tube of a control valve via a body of the internally-connected faucet, and the other end of the flexible connection tube is connected with a water head, wherein the water head is engaged on an outer wall of the outlet pipe, such that the flexible connection tube is pulled to a desired position with the water head when desiring to wash the countertop or to the other ranges based on user requirements, thus obtaining a flexible application.
- However, the flexible connection tube of the outlet pipe of the conventional structure drops downward because of gravity causing friction between the flexible connection tube and an inner wall of the outlet pipe. Furthermore, a skewed movement and a block of the flexible connection tube will occur, when pulling the flexible connection tube outward or retracting the flexible connection tube inward.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- The primary aspect of the present invention is to provide a bendable positioning structure of an outlet pipe for a faucet by which a flexible connection tube is slidably received in a spring tube of the outlet pipe and is limited by a small-diameter portion of a spring tube so that the flexible connection tube is fixed on a centrally-axial line of the output tube, a friction between the flexible connection tube and an inner wall of the outlet pipe, a skewed movement and a block of the flexible connection tube are avoidable, when pulling the flexible connection tube outward or retracting the flexible connection tube inward.
- To obtain the above-mentioned aspects, a bendable positioning structure of an outlet pipe for a faucet provided by the present invention contains a body, a spring tube, and a flexible connection tube.
- The body includes a columnar holder, the outlet pipe connected to a top of the holder, and a fixer connected to an end of the outlet pipe away from the columnar holder.
- The spring tube is made of a metal wire and is spirally tubular. The spring tube is fitted in the outlet pipe and is stopped and positioned by the fixer, the spring tube includes a large-diameter portion and a small-diameter portion which are alternatively formed along the spring tube. The large-diameter portion abuts against an inner wall of the outlet pipe.
- The flexible connection tube is slidably received in the spring tube of the outlet pipe to be limited by the small-diameter portion of the spring tube so that the flexible connection tube is fixed on a centrally-axial line of the output tube. An outer wall of an end of the flexible connection tube is connected with a water head, and the water head is engaged on an edge of the outlet pipe and is pulled outward with the flexible connection tube based on user requirements.

FIG. 10 is an amplified cross-sectional view of a portion A2 ofFIG. 9 . - With reference to
FIGS. 1-6 , a bendable positioning structure of an outlet pipe for a faucet according to a first embodiment of the present invention comprises abody 10, aspring tube 20, and aflexible connection tube 30. - The
body 10 includes acolumnar holder 11, a water-supply control portion 12 connected on a side of thecolumnar holder 11, theoutlet pipe 13 connected on a top of thecolumnar holder 11, being flexibly bendable and having an internal diameter D1, and afixer 14 connected with an end of theoutlet pipe 13 away from thecolumnar holder 11 and being annular. - The
spring tube 20 is made of a metal wire and is spirally tubular, wherein thespring tube 20 is deformably fitted in theoutlet pipe 13 and is stopped and positioned by thefixer 14, thespring tube 20 includes a large-diameter portion 21 and a small-diameter portion 22 which are alternatively formed along thespring tube 20, wherein the large-diameter portion 21 has an external diameter D2 which is greater than or equal to the internal diameter DI of theoutlet pipe 13, and the large-diameter portion 21 abuts against an inner wall of theoutlet pipe 13 so that thespring tube 20 is fitted in theoutlet pipe 13 securely. - The
flexible connection tube 30 is slidably received in thespring tube 20 of theoutlet pipe 13 to be limited by the small-diameter portion 22 of thespring tube 20 so that theflexible connection tube 30 is fixed on a centrally-axial line of theoutput tube 13, wherein an outer wall of an end of theflexible connection tube 30 is connected with awater head 31, and thewater head 31 is engaged on an edge of theoutlet pipe 13 and is pulled outward with theflexible connection tube 30 based on user requirements. - In operation, the water-
supply control portion 12 is operated to control a mixing ratio of cold water and hot water, a water supply, and a water stop, such that a water flow of the cold water and the hot water is supplied from thewater head 31 of theflexible connection tube 30. As desiring to wash a countertop or supplying the water flow within a large range, as shown inFIG. 7 , thewater head 31 is pulled outward to a desired position with theflexible connection tube 30 and then is retracted inward so that thewater head 31 moves back to an original position (now shown) automatically, and theflexible connection tube 30 is actuated by thewater head 31 to retract back to an original position. Since an automatic return of thewater head 31 and theflexible connection tube 30 is a well-known art, further remarks are omitted. - Referring to
FIGS. 8-10 , a difference of a bendable positioning structure of an outlet pipe for a faucet of a second embodiment from that of the first embodiment of the present invention comprises a coveringlayer 23 covered on thespring tube 20 and configured to contact with the inner wall of theoutput tube 13 and the outer wall of theflexible connection tube 30. - Thereby, the bendable positioning structure of the present invention has advantages as follows: the
flexible connection tube 30 is slidably received in thespring tube 20 of theoutlet pipe 13 and is limited by the small-diameter portion 22 of thespring tube 20 so that theflexible connection tube 30 is fixed on the centrally-axial line of theoutput tube 13, a friction between theflexible connection tube 30 and the inner wall of theoutlet pipe 13, a skewed movement and a block of theflexible connection tube 30 are avoidable, when pulling theflexible connection tube 30 outward or retracting theflexible connection tube 30 inward. - While the first embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. The scope of the claims should not be limited by the first embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
