Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an operating structure for a water stop valve for a washbasin bowl, and more specifically, to maintain a good appearance of the operating part over a long period of time, and to prevent water leakage from the operating part. Regarding prevention technology.

[Background Art] Conventionally, in the operating structure of a water stop valve for a wash bowl, which opens and closes the bottom opening of the wash bowl, the water stop valve is opened and closed by pushing down and pulling up an operating tool provided at the upper part of the back of the wash bowl. As shown in the figure, a rod-shaped operating tool 4 is inserted through a guide tube 6 that is fixed to a mounting hole 5 provided at the rear upper part of the washing bowl so as to be able to be pushed down and pulled up. , water leaks from the gap between the rod-shaped operating tool 4 and the guide tube 6, and the metal guide tube 6 and operating tool 4 come into sliding contact, causing both to wear out.
In particular, there was a problem in that the plating on the guide tube 6, which also served as the flanged decorative ring 7, peeled off, degrading the appearance.

[Purpose of the invention] The present invention was created in view of the above problems, and its purpose is to maintain the good appearance of the operation part over a long period of time, while also reducing the amount of noise from the operation part. To provide an operating structure for a stop valve of a washbasin bowl that can prevent water leakage.

[Disclosure of the invention] The operating structure of the water stop valve of the washing bowl of the present invention is such that the water stop valve 3 for opening and closing the bottom opening 2 of the washing bowl 1 is operated by pushing down and pulling up an operating tool 4 provided at the top of the back of the washing bowl 1. This is an operating structure for a stop valve for a washbasin bowl that is opened and closed, and a recess 9 is formed in a decorative ring 7 with a flange arranged on the upper surface of the periphery of a mounting hole 5 formed on the upper periphery of the washbowl 1. , O in recess 9
The threaded part 10 on the upper outer surface of the guide tube 6, which houses the ring 8 and is inserted into the mounting hole 5 so as to be prevented from coming off upward, is screwed into the threaded hole 12 formed on the lower inner circumferential surface of the flanged decorative ring 7. At the same time, the O-ring 8 is positioned, and the inner diameter of the O-ring 8 is deformed to be smaller than the through hole 13 of the flanged decorative ring 7 and the inner diameter of the guide cylinder 6, and the flanged decorative ring 7, O-ring 8, and guide are It is characterized in that the rod-shaped operating tool 4 is inserted into the cylinder 6 so as to be able to be pushed down and pulled up, and by configuring it in this way, the above object is achieved. In other words, the guide tube 6
The threaded portion 10 on the upper outer surface of the O-ring 8 is screwed into the screw hole 12 formed on the lower inner peripheral surface of the flanged decorative ring 7, and the inner diameter of the O-ring 8 is adjusted to the through hole 13 of the flanged decorative ring 7 and the inner diameter of the guide tube 6. Since the inserted operating tool 4 can be brought into sliding contact with the O-ring 8, water leakage between the rod-shaped operating tool 4 and the guide tube 6 can be prevented, and the operating tool 4 and the flanged decorative ring 7 can be avoided, and the flanged decorative ring 7
Moreover, the plating of the operating tool 4 does not need to be peeled off, and a good appearance can be maintained for a long period of time.

Embodiments of the present invention will be described in detail below based on the drawings.

Figure 3 shows the schematic configuration of the washbasin bowl 1.
The water stop valve 3 that opens and closes the bottom opening 2 of the wash basin 1
Opening/closing operations can be performed via an intermediate link mechanism 14 by pushing down and pulling up a bar-shaped operating tool 4 provided at the upper part of the rear side. The configuration of the intermediate link mechanism 14 can be modified in various ways, and in short, the stop valve 3 is closed by pulling up the operating tool 4, and opened by pushing down the operating tool 4. I wish I could.

A mounting hole 5 is formed in the upper peripheral edge of the washbowl 1. A through hole 13 is formed in the flanged decorative ring 7 arranged on the upper surface of the periphery of the attachment hole 5. A recess 9 having a larger diameter than the through hole 13 is formed in the flanged decorative ring 7 so that the O-ring 8 can be housed in the recess 9. A screw hole 12 having a larger diameter than the recess 9 is formed below the flanged decorative ring 7.
A threaded portion 10 is formed on the outer periphery of the guide tube 6 which can be inserted into the mounting hole 5. A holding portion 15 is formed at the upper end of the guide tube 6 and can be inserted into the recess 9. A driver groove 16 is formed at the lower end of the guide tube 6. Then, insert the O-ring 8 into the recess 9 of the flanged decorative ring 7, rotate the guide tube 6 with a screwdriver, screw the threaded part 10 into the screw hole 12, and position the O-ring 8. At the same time, the inner diameter of the O-ring 8 is deformed to be smaller than the inner diameter of the through hole 13 of the flanged decorative ring 7 and the guide tube 6, and the guide tube 6 is inserted into the mounting hole 5.
and place the flanged decorative ring 7 above the periphery of the mounting hole 5 via the gasket 17. Then, the nut 19 is screwed onto the guide cylinder 6 via the packing 17 and the washer 18, and the installation is carried out as shown in FIG. Next, the rod-shaped operating tool 4 is inserted into the flanged decorative ring 7, the O-ring 8, and the guide tube 6 so as to be able to be pushed down and pulled up, and the lower end of the operating tool 4 is connected to the intermediate link mechanism 14. Incidentally, such installation and assembly procedures may be modified as appropriate to facilitate the work.

According to such a configuration, the threaded portion 10 on the upper outer surface of the guide tube 6 is screwed into the screw hole 12 formed on the lower inner circumferential surface of the flanged decorative ring 7, and the inner diameter of the O-ring 8 is connected to the flanged decorative ring. 7 through hole 13 and guide tube 6
By deforming the O-ring to be smaller than the inner diameter, the inserted operating tool 4 can be brought into sliding contact with the O-ring 8, preventing water leakage between the rod-shaped operating tool 4 and the guide tube 6, Moreover, sliding between the operating tool 4 and the flanged decorative ring 7 is avoided, the plating of the flanged decorative ring 7 and the operating tool 4 is not peeled off, and a good appearance is maintained over a long period of time.

A shower body 21 is attached to the washbasin bowl 1 via piping 20. This shower body 21 consists of a shower head 22 and a head holding part 23 that holds the shower head 22 by spline fitting, and the tips of the spline teeth 24 in the spline structure of each shower head 22 are as shown in FIGS. 6 to 9. The tip is sharpened into a spear shape to facilitate spline fitting. Since spline fitting can be easily performed in this way, the fitting tolerance (clearance) of spline fitting can be kept small, and the fitting force can be increased in the spline fitting state, so that the spline can be strongly Because it can be fitted, water pressure allows
There is no need for the shower head 22 to fall out.

[Effects of the invention] In summary, the present invention has the threaded part on the upper outer surface of the guide cylinder screwed into the screw hole formed on the lower inner circumferential surface of the flanged decorative ring, so that the inner diameter of the O-ring can be connected to the threaded part of the flanged decorative ring. Since the deformation is made smaller than the inner diameter of the hole and the guide tube, the inserted operating tool can be brought into sliding contact with the O-ring, preventing water leakage between the rod-shaped operating tool and the guide tube. There are advantages in that sliding between the operating tool and the flanged decorative ring can be avoided, and a good appearance can be maintained over a long period of time without peeling off the plating on the flanged decorative ring and the operating tool.
