Regarding the device. Specifically, the present invention relates to a water tank drain plug device that is extremely easy to repair and is suitable for installation in a bathtub.

[0002]

2. Description of the Related Art Conventionally, a drain plug of a drain plug device for a water tank of this type is attached to a drain port at the bottom of a bath, and an operation unit for opening and closing a valve body of the drain plug is provided on a flange of the bath. An example will be described with reference to FIGS.

A drain plug 14 is attached to a drain port 12 on the bottom surface 10 of the bathtub, an operating device 20 is attached to a mounting port 18 of a flange portion 16 of the bath, and the drain plug 14 and the operating device 20 are connected by an operating cable 22. ing.

The drain plug 14 has a cylindrical lower casing 24.
And an upper casing 26 screwed to the lower casing 24 from above, and a valve seat portion 28 is provided around the inner peripheral surface of the upper end of the upper casing 26. A valve body 30 is provided so as to be seated on the valve seat portion 28.

One end of the operation cable 22 is inserted into the lower casing 24 through a cable insertion hole 24h on the side peripheral surface thereof, and one end of the operation cable 22 is a mechanical box (valve body advancing / retreating device) 32. It is connected to the.

The operation cable 22 is a hollow guide 22.
a, a wire 22b inserted into the guide 22a, and a terminal 22c attached to the other end of the guide 22a.
It has and. This guide 22 is attached to the mechanical box 32.
a is attached, and the wire 22b is attached to the mechanical box 32.
It is drawn in.

The mechanical box 32 raises the valve body 30 when the wire 22b is pushed in, and stops the valve body 30 at the pushed-up position. Then, when the wire 22b is pushed again, the valve body 30 is lowered. In addition, such a mechanical box 32 is disclosed in Japanese Utility Model Publication No. 60-22147.
It is made publicly known in the publication.

An arm-shaped bracket 34 projects from the inner peripheral surface of the upper casing 26 in the center direction, and the flange portion 3 of the mechanical box 32 is provided above the bracket 34.
2a are overlapped and the bolt 36 is tightened from above.

As shown in FIG. 5, a rod 30a projects from the lower surface of the center of the valve body 30, and the rod 30a is inserted into the mechanical box 32.

The operating device 20 includes a lower housing 40.
The push button 46 is slidably fitted in a tubular housing 44 having an upper housing 42 screwed into the lower housing 40 from above. The upper housing 42 has a container (cup) shape, and the terminal 22c is fixed to the bottom 42a of the upper housing 42 by a bolt 48 screwed from above.

The wire 22b of the operation cable 22 is
It passes through the terminal 22c and is fitted into a receiving hole 46a provided in the push button 46. In addition, terminal 22
A guide 22a is fixed to c.

In this water tank drain plug device, the drain plug 1
When repairing the valve body 30 or the mechanical box 32 of 4,
As shown in FIG. 5, first, the valve element 30 is pulled upward and pulled out, and then the bolt 36 is removed. After that, the mechanical box 32 is pulled and lifted, and the end portion of the guide 22a is pulled out upward. Then, the tip of the guide 22a of the operation cable 22 is firmly sandwiched by a tool such as radio pliers 50, and the mechanical box 32 is rotated counterclockwise to separate the mechanical box 32 from the operation cable 22.

[0013]

As described above, when repairing the drain plug 14 in the conventional water tank drain plug device, it is necessary to firmly pinch the tip of the operation cable 22 with the radio pliers 50 or the like. However, since there is almost no play in the operation cable 22, the tip of the operation cable 22 can be pulled out only slightly from the bracket 34.

Therefore, there is a very small gap between the lower surface of the flange portion 32a of the mechanical box 32 and the bracket 34. Moreover, since the drain plug 14 is provided at the drain port 12 at the corner of the bath bottom surface 10,
Radio pliers 5 in this narrow space in a difficult working position
It is necessary to insert the tip of 0 and firmly sandwich the guide 22a.

Therefore, in the conventional water tank drain plug device, the mechanical box 32 is connected to the operation cable 22.
It was extremely difficult to remove from.

[0016]

According to another aspect of the present invention, there is provided a drainage tap device for a water tank, wherein the drainage plug is installed at a drainage port at the bottom of the water tank and is connected to the drainage plug via an operation cable so as to be remotely controllable.
