Description

[Detailed description of the invention] [Industrial application field] The present invention is a water faucet spouting device for connecting the water spouting device to a circular water spout pipe connected to the faucet in a state where the spouting device cannot be rotated relative to the faucet and cannot be pulled out. It is related to the connection structure.

[Conventional technology]

For example, a horizontally oriented circular water discharge pipe connected to a hot water mixing faucet so as to be rotatable around the vertical axis,
Conventionally, when connecting downward water discharging type water discharging tools, as shown in FIG.
The cylindrical part 22 of the water spouting tool 21 is fitted into the tip of a circular water spouting pipe 25 rotatably equipped with a gasket holder 24 on the tip side, and the gasket 23 is pressed through the gasket holder 24. Screw member 2
6 is screwed onto the cylindrical portion 22.

[The problem that the idea aims to solve]

In the above configuration, the prevention of rotation and removal of the water discharging tool 21 from the circular water discharging pipe 25 depends on the pressing force of the packing 23 by the screw member 26.

If the threaded member 26 is not tightly tightened to the cylindrical portion 22, or if the threaded member 26 is loosened due to long-term use, the water discharging tool 21 may move around the horizontal axis of the circular water discharging pipe 25. Therefore, when the water spouting tool 21 is held and the circular water spouting pipe 25 is turned around the vertical axis in order to change the downward water spouting position of the water spouting tool 21, the However, the water discharging tool 21 rotates about the horizontal axis, causing the downward direction of the water discharging direction of the water discharging tool to be directed in an unexpected direction, resulting in the inconvenience of wetting surrounding objects with water.

In addition, there was also an inconvenience that the water spouting tool 21 sometimes slipped out of the circular water spouting pipe 25 when strong water pressure was applied to the water spouting tool 21.

An object of the present invention is to provide a connection structure for a water spout that can reliably prevent the water spout from rotating and coming off from the circular water spout pipe even if the screw member is insufficiently tightened or loosens to some extent. be.

[Means to solve the problem]

In order to achieve the above object, the present invention provides the above-mentioned water discharging tool connection structure, in which an engaging recess is partially formed in the circumferential direction on the end surface of the water discharging pipe connecting cylindrical portion of the water discharging tool, and An engaging member that can be freely engaged and detached from the engaging recess is provided on the circumferential surface of the circular water spout that is inserted into the cylindrical portion in a watertight manner, and the water is discharged from the circular water spout by acting on the engaging member. The device is characterized in that a retaining portion that prevents the tool from coming off is provided on a screw member that is screwed onto the cylindrical portion.

[Effect]

According to the above characteristic structure, by engaging the engagement member on the circular water discharge pipe side with the engagement recess on the water discharge tool side,
By preventing the water spouting tool from rotating with respect to the circular water pipe, and by screwing the screw member into the cylindrical part,
The water spouting tool is prevented from coming off from the circular water spouting pipe through the engagement member.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

1 and 2 show the whole of a hot water mixing faucet 2 to which a water spouting device 1 is connected, and hot water and water introduction portions a and b.
The faucet body 3 has a built-in hot water mixing part (not shown), and is equipped with an operating lever 4 for adjusting the hot water mixing ratio and water volume. A water discharge pipe 5 is connected to the faucet main body 3 so as to be rotatable about the vertical axis.

The water spouting device 1 is of a downward water spouting type, and is connected to the circular water spouting pipe 5 in such a manner that it cannot be rotated relative to the distal end thereof and cannot be removed.

A specific example of the connection structure of the water discharging tool 1 to the circular water discharging pipe 5 will be explained based on FIGS. 3 and 4.

That is, a semicircular engagement member 6 is connected to the distal end side of the circular water discharge pipe 5 by means of press fastening or the like, and an O-
The ring 7 is fitted and held, and the engagement member 6
Also, prior to attaching the O-ring 7, the screw member 9, which is provided with a retaining ring 8 that comes into contact with the engaging member 6 and a retaining portion c that comes into contact with the retaining ring 8, is attached to the circular hole. It is externally fitted to the water pipe 5.

On the other hand, an engagement recess 1 having a shape corresponding to the engagement member 6 is formed on the end surface of the cylindrical portion 10 of the water discharge tool 1 into which the O-ring 7 of the circular water discharge pipe 5 is fitted in a watertight state.
1, and a male threaded portion d is formed on the circumferential surface of the cylindrical portion 10.

Then, the circular water spouting pipe 5 with the O-ring 7 externally fitted is fitted into the cylindrical portion 10 of the water spouting tool 1 in a watertight state, and the engaging member 6 of the circular water spouting pipe 5 is fitted.
is engaged with the engagement recess 11 of the cylindrical portion 10, and
A screw member 9 is screwed onto the male threaded portion d of the cylindrical portion 10, and the retaining ring 8 is connected to the engagement member 6 and the cylindrical portion 1 by the retaining portion c of the screw member 9.
It is pressed against the end face of 0.

According to the above configuration, by engaging the engagement recess 11 of the water discharging device 1 with the engaging member 6 of the circular water discharging pipe 5, rotation of the water discharging device 1 with respect to the circular water discharging pipe 5 is prevented. , and the retaining portion c of the screw member 9 screwed onto the cylindrical portion 10 is locked to the engagement member 6 of the circular water discharge pipe 5 via the retaining ring 8, so that the circular The water discharging tool 1 is prevented from coming off from the water discharging pipe 5.

Therefore, even if the screw member 9 is not tightly tightened to the cylindrical portion 10, the water spouting tool 1 is reliably prevented from rotating and coming off from the circular water spouting pipe 5.
Therefore, when the circular water spouting pipe 5 is rotated around the vertical axis by holding the water spouting tool 1 in order to change the downward water spouting position of the water spouting tool 1, the water spouting tool 1
Rotating around the horizontal axis is reliably prevented, and the water spouting tool 1 is also reliably prevented from slipping out of the circular water spouting pipe 5 due to water pressure.

FIG. 5 shows another embodiment of the water discharging device connection structure. In this device, two pin-shaped engaging members 6 are attached to the circular water discharge pipe 5 with a phase of 180 degrees by means such as brazing, and a plurality of evenly divided pieces (four pieces are shown in the figure) are equally spaced. The number of engagement recesses 11 shown in FIG.
By selectively engaging the engaging members 6 individually, the angle at which the water spouting tool 1 is attached to the circular water spouting pipe 5 can be changed every 90 degrees.

Note that in the above configuration, the engagement member 6 is
In this configuration, it is not necessary to divide the plurality of engaging members 6 into even numbers at equal intervals. Alternatively, the engaging members 6 may be provided to correspond to all of the engaging recesses 11.

[Effect of idea]

As explained above, according to the faucet water spout fitting connection structure according to the present invention, it is possible to simultaneously and reliably prevent the water spout from turning and coming off with respect to the circular water spout pipe connected to the faucet. As a result, the water spouting direction of the water spouting tool is reliably prevented from changing, and the water spouting tool is prevented from coming out of the circular water spouting pipe, and although it is a simple improvement, the conventional drawbacks can be rationally solved.
