Description

[Detailed description of the invention] (Industrial application field) This invention is based on a system that is formed on the bottom plate of a cabinet in order to connect a drainage pipe hanging down from a water tank such as a sink or washstand to a sewage pipe rising from the floor. The present invention relates to a sealing plate for sealing an opening for drain pipe insertion.

(Prior art) Conventionally, the drain pipe that hangs down from the water tank of a sink, washstand, etc. is inserted and connected to a sewer pipe that rises from the floor of the house through an opening formed in the bottom plate of the cabinet. .

In order to prevent odor and moisture from rising from below through the gap between the hanging drain pipe and the opening in the cabinet bottom plate, or to prevent cockroaches from entering, install a rubber plate or the like on the drain pipe. The opening of the bottom plate is closed by inserting a disc-shaped closing plate made of the bottom plate into the bottom plate. However, since the outer diameter of the drain pipe that hangs down from the water tank differs depending on the model, it is necessary to prepare a plurality of sealing plates that match the diameter of the drain pipe, which is inconvenient.
In addition, since the position of the sewer pipe rising from the floor of the house and the position of the water tank's drain outlet are not necessarily coaxial, the position of the drainage pipe insertion hole formed in the sealing plate is changed. It was also necessary to prepare multiple types of blocking plates.

(Problems that the invention aims to solve) This invention aims to eliminate the drawbacks of conventional sealing plates and to be able to seal multiple types of drainage pipe diameters. It is something to do.
It is also intended to be able to accommodate differences in the positions of the water tank drain and the sewer pipe.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by this invention is that the drain pipe 3 connected to the water tank drain port is inserted into the drain pipe 3, and is formed on the bottom plate 4 of the cabinet. A sealing plate 8 that closes the opening 5 is formed into a disk shape with an elastic sealing material such as rubber, and has circular grooves 1 cut into different diameters corresponding to the outer diameter of the drain pipe 3.
0 are formed on concentric circles, and the pipe insertion hole 9 is formed by cutting along the cut circular groove 10.

(Operation) A pipe insertion hole is formed by cutting along the cut circular groove. By selecting a cut circular groove with a diameter corresponding to the outer diameter of the drain pipe, it is possible to obtain a pipe insertion hole with an optimal diameter for inserting the drain pipe.

By selecting cut circular grooves with different center positions in accordance with the insertion position of the drain pipe, the pipe insertion hole can be formed at the optimal position for inserting the drain pipe.

(Effects of the invention) According to this invention, by selecting and cutting out the cut circular groove of the required diameter, it is possible to form a pipe insertion hole that matches the outer diameter of the drain pipe. There is no gap between the drain pipe and the drain pipe, and the intrusion of odors, moisture, cockroaches, etc. can be reliably prevented.

Furthermore, by selecting the position of the cut circular groove to be cut out, it is possible to position the pipe insertion hole approximately on the same axis as the drain port of the water tank and the sewer pipe.

(Embodiments) Preferred embodiments of this invention will be described below with reference to the drawings. In the figure, 1 is a water tank of a sink, and a bellows-shaped drain pipe 3 is connected to a drain port 2. The drain pipe 3 extends downward through a large diameter opening 5 formed in the bottom plate 4 of the cabinet, and is inserted into and connected to a sewer pipe 6 rising from the floor of the house.

The opening 5 in the bottom plate has a size sufficient to cover fluctuations in the upright position of the sewer pipe 6, and prevents the occurrence of the inconvenience that the opening 5 and the sewer pipe 6 do not match. The periphery of the opening 5 is formed with a step 7 recessed slightly downward, and a disk-shaped sealing plate 8 according to the present invention is disposed with its peripheral edge placed and supported on the step 7.
The opening 5 is closed. The sealing plate 8 has a thickness that is substantially the same as the height of the stepped portion 7, and the upper surface of the sealing plate 8 is flush with the bottom plate 4. Note that the peripheral edge of the opening 5 does not necessarily have to be the stepped portion 7 as shown in the figure. The sealing plate 8 is made of rubber,
Made of elastic sealing material such as soft plastic,
A pipe insertion hole 9 is provided through which the drain pipe 3 is inserted. The pipe insertion hole 9 substantially matches the outer diameter of the drain pipe 3 and can contact the outer peripheral surface to seal the gap.

Three cut circular grooves 10 located concentrically are formed in the sealing plate 8. Each cut circular groove 10 is cut out with a cutter 11 along the cut circular groove 10 having a diameter corresponding to a different outer diameter of the drain pipe 3 to create a pipe insertion hole 9. Note that the number of cut circular grooves 10 is not limited to three.

The cut circular grooves 10 are preferably formed at two or more locations with different center positions. As a result, even if the position of the drain pipe 6 is shifted from the center of the opening 5, the position of the pipe insertion hole 9 can be formed approximately on the same axis, and the connection between the drain pipe 3 and the drain pipe 6 can be made. can be done without any problems.

In addition, as shown in FIG. 1, the position of the drain port 2 formed in the water tank 1 may be shifted back and forth depending on the model, but even in such cases, the drain port 2 and the sewer pipe 6 By cutting out the notched circular groove 10 in which the grooves 10 and 10 are aligned substantially on the same axis, and rotating the sealing plate 8 within the stepped portion 7 or moving it on the bottom plate, the drain port 2, the sewer pipe 6 and the pipe insertion hole 9 can be located substantially on the same axis, and the drain pipe 3 can be inserted therethrough and connected.

In this way, a pipe insertion hole 9 having a required diameter and position is formed in the sealing plate 8, and the drain pipe 3 is inserted into the pipe insertion hole 9, and the pipe insertion hole 9 is disposed inside the stepped portion 7, thereby sealing the opening 5. The sealing plate 8 has adhesive tape 1 fixed on the back side.
2, it is adhesively fixed onto the stepped portion 7.
