Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of a water faucet in which an auxiliary spout pipe of a desired shape can be replaced at the spout of the faucet.

[Conventional technology and its problems]

In everyday homes, there are many requests to change the height and water supply direction of a faucet in a kitchen sink at any time, depending on the intended use. Even if the parts were integrally constructed or rotatably connected using cap nuts, it was not planned that this part would be replaced, so a wrench or other tool would be required to attach or remove it. However, it was not possible to easily change the height of the spout in a typical household.

On the other hand, in recent years, the above-mentioned water discharge pipe has been made up of two parts and both pipes can be connected with a fixing screw, or the joint ends of both pipes are provided with L-shaped locking notches and protrusions that can be joined to each other. Some water supply faucets have been found that connect the two pipes, but the former requires time and effort to attach and detach, especially in ordinary households, and the latter allows the auxiliary water pipe to come off during use. There was still room for improvement, as there was a risk of it coming off (Utility Model Publication No. 56-23422,
(Refer to Utility Model Publication No. 48-4288).

[Means for solving problems]

Therefore, the present invention proposes a water faucet in which the faucet main body's water discharge pipe and the auxiliary water faucet pipe can be freely connected via an engaging part provided at the joint end of the two pipes. Consisting of a key-shaped locking hole opened at the tip and a connecting fitting to which elastic packing is attached as a ring and fitable into the through hole of the auxiliary water discharge pipe,
By preparing in advance several types of auxiliary water discharge pipes with shapes depending on the purpose, it is possible to easily replace a water faucet with a shape according to the purpose and use in a general household.

[Effect]

The water faucet of the present invention has the effect that the auxiliary spout pipe can be easily and reliably attached and detached by pressing the connecting fitting.

〔Example〕

Hereinafter, the configuration of the present invention will be described in more detail based on examples. In Figs. 1 and 2, 1 has one end as a water discharge pipe A, the other end as a main pipe connection part B, and a valve chamber C in the middle. 2 is a key-shaped locking hole opened at the tip of the water spout A, or 3 is the water spout 3a at the tip, and the base end is the water spout 3a.
An auxiliary spout pipe that can be fitted externally to the auxiliary spout pipe, and 4 is a connecting fitting that is fitted into a through hole 3b on the base side of the auxiliary spout pipe, and an elastic packing 5 is attached to the rod 4a, and a push plate 4b at the upper end is pressed. By pressing, the circular seat plate 4c at the lower end can be elastically moved by a certain amount.

Note that 6 in the figure indicates an O-ring.

Next, to describe an example of use and the function and effect of the above-mentioned water supply faucet, when attaching the auxiliary water-discharge pipe 3 according to the purpose of use to the main body-side water-discharge pipe A, press the connecting fitting 4 fitted into the above-mentioned auxiliary water-discharge pipe 3. Push down the board 4b, and insert the rod into the circular hole 2a of the key-shaped locking hole 2 of the water discharge pipe A on the main body side with the rod 4a and seat plate 4c exposed inside the pipe. After that,
If the pressing of the pressing plate 4b is released, the seat plate 4c
is pushed back by the elastic force of the packing 5 and fitted into the circular hole portion 2a of the locking hole, and both of the water discharge pipes A and 3 are
are securely joined, and at the same time, the packing 5 and the O-ring 6 provide the engaging portion with high watertightness.

Further, it goes without saying that the auxiliary water discharge pipe 3 may have a distal end rotatable via a connecting member 7 as shown in FIG. 3.

[Effect of idea]

As described above, the water faucet according to the present invention allows the seat plate 4c of the connecting fitting to be elastically engaged with the key-shaped locking hole 2, so that it can be used at any time in a general household as a water spout according to the purpose. The auxiliary water discharge pipe 3 having the height and direction 3a exhibits excellent practical effects such as being able to be reliably attached and detached with one touch without using any tools.
