An object of the present invention is to solve the above-mentioned conventional problems and to provide a nozzle of a bubble bath, a nozzle mounting structure of the bubble bath, and a packing capable of easily mounting the nozzle to the bath.

[0008]

According to the present invention, there is provided a structure for mounting a fumarolic nozzle, wherein a nozzle is mounted on a nozzle mounting hole of a bubble bath, wherein the nozzle comprises a nozzle body disposed outside the bath tub, A mounting cylinder screwed into the nozzle body from the inside of the bathtub through the nozzle mounting hole, and flanges respectively provided on the mounting cylinder and the nozzle body are arranged so that a peripheral portion of the nozzle mounting hole of the bathtub is connected to the bathtub. In the nozzle mounting structure of the bubble bath tub which is sandwiched from inside and outside and packing is interposed between each flange and the bath tub, the packing inside the bath tub and the packing outside the bath tub are integrated. And the packing holds the flange of the nozzle body.

The packing of the present invention is used in this structure, and includes a cylindrical portion inserted into the nozzle mounting hole, and a radially extending direction from one end of the cylindrical portion in the direction of the axis of the cylindrical axis. A protruding plate-shaped flange portion and a protruding portion are provided in the diameter-enlarging direction at the other end value of the cylindrical portion in the direction of the axis of the cylinder. And a U-shaped flange portion having a U-shaped cross-sectional shape so as to go around the surface and reach the other plate surface of the flange.

According to the structure and the packing, the packing holds the flange of the nozzle body so that the packing cannot be removed from the nozzle body. The packing is inserted into the nozzle mounting hole of the bathtub, and the packing (especially the flat plate) (Flange) is locked to the peripheral edge inside the bathtub in the nozzle mounting hole of the bathtub.

With this arrangement, even if the user releases his / her hand from the nozzle body, the nozzle body is held in the bathtub via the packing. Therefore, the nozzle can be fixedly attached to the bathtub by screwing the mounting cylinder into the nozzle body from the inside of the bathtub.

When a cylindrical guide is protruded from the nozzle body and the cylindrical guide is inserted into the nozzle mounting hole of the bathtub, the center line of the nozzle body is held perpendicular to the outer surface of the bathtub (the nozzle body is not closed). Tilting is prevented). Further, the mounting cylinder is guided by the cylindrical guide portion, approaches the nozzle body, and the mounting cylinder is screwed into the nozzle body in a state where the center line of the nozzle body and the center line of the mounting cylinder coincide with each other. Become. For this reason, the screw of the mounting cylinder is correctly engaged with the screw of the nozzle body.

By making the cylindrical guide portion tapered, it becomes easy to insert the cylindrical guide portion into the cylindrical portion of the packing.

By providing a recess on the outer periphery of the base end of the cylindrical guide portion and a protrusion on the inner surface of the packing, the waterproof property is improved.

In the present invention, the cylindrical guide portion, the cylindrical portion of the mounting cylinder, and the nozzle mounting hole are formed in a rectangular shape, thereby preventing the nozzle body from rotating together when the mounting cylinder is screwed into the nozzle body. it can.

When mounting the packing 25, the packing 25 is attached to the nozzle body 22, and the flat flange 25a of the packing 25 is locked around the mounting hole of the bathtub 7. In a state where the flange 25 a is locked to the peripheral edge of the mounting hole of the bathtub 7, the nozzle body 22 is held in the bathtub 7 via the packing 25 even when the hand is released from the nozzle body 22. Therefore, even for one worker, first, the nozzle body 22 is temporarily fixed to the outside of the bathtub 7 via the packing 25, and then the worker goes into the inside of the bathtub 7 to attach the mounting cylinder 23 to the nozzle. Can be screwed into the body. Thus, even a single worker can attach the fumarole nozzle 22 to the bathtub 7 very easily.

Moreover, in this embodiment, since the cylindrical guide portion 22b is inserted into the nozzle mounting hole 8, the center line of the nozzle body 22 is perpendicular to the outer surface of the bathtub 7. Moreover, the mounting cylinder 23 is guided by the cylindrical guide portion 22b, approaches the nozzle body 22, and is then screwed. Therefore, the center line of the mounting cylinder 23 and the nozzle body 2
Since the mounting cylinder 23 is screwed into the nozzle body 22 in a state where the center line of the mounting cylinder 2 and the center line coincide with each other, the male screw of the mounting cylinder 23 is properly engaged with the female screw of the nozzle body 22.

In the above embodiment, the spout cap 24 and the mounting cylinder 23 are separate bodies, but in the present invention, both may be integrated.

By forming a cut in the U-shaped flange 25c of the packing 25, the U-shaped flange 25c can be easily mounted on the flange 22a.

It should be noted that the present invention has an advantage that not only the work of attaching the blast nozzle 20 to the bathtub 7 becomes easy, but also the inspection work of the blast nozzle 20 attached to the bathtub 7 can be easily carried out. That is, in the state shown in FIG. 1, when the spout cap 24 is removed from the mounting cylinder 23, and then the mounting cylinder 23 is rotated and removed from the nozzle body 22, the flat flange portion 25a of the packing 25 competes with the bathtub 7. Therefore, even if the mounting cylinder 23 is removed, the nozzle body 2
2 is held in a bathtub 7. Accordingly, it is possible to easily clean and repair the inside of the nozzle body 22 and the mounting cylinder 23 or replace the mounting cylinder 23 by removing the mounting cylinder 23.
