When the water stop is closed, the drain plug is located above the drain port bracket in the drain port where accuracy is difficult to collect. However, in terms of water stoppage, it is difficult to seal the water stop because the inside of the drainage port is not elaborate, and it is difficult to form an elaborate drainage port together with the drainage port fitting in the water tank. In addition, when it comes to a water tank such as pottery, it is difficult to form a more precise drainage port part, it is difficult to obtain accuracy, and water stoppage at the drainage port part with poor elaboration impairs the sealing performance. In addition, the water stop in the closed state by the packing adjacent to the bottom of the lid covers the edge of the stopper lid against the inner surface of the drainage port before contact by the packing, resulting in insufficient sealing by the packing and causing trouble. It is inconvenient.
Furthermore, when the water stop by the drain plug at the drain port that gradually decreases in diameter, the drain plug fits into the wedge-shaped drain port, and the operation from the fitted state to the pull-out state of the drain plug becomes heavy. It ’s not good.

  Therefore, the present invention provides a cover that can be moved up and down in the depressed portion so as to prevent the drainage fitting that is sandwiched and attached to the inward flange portion of the depressed portion from being formed in the depressed portion at the bottom of the water tank. In order to ensure water stoppage, the packing is brought into contact with a drainage fitting that is processed elaborately. And it aims at obtaining such a drain plug device.

  In the drain plug device of the present invention, a cylindrical depression is formed at the bottom of the water tank, and an inward flange formed on the depression is sandwiched and attached between the drain fitting and the connection pipe. The drain port portion is provided with a cover that is moved up and down in the depressed portion to be substantially flush with the bottom surface of the water tank. A drain plug provided with a shaft portion for inserting and holding is constructed, and is opened and closed by raising and lowering the drain plug.

  In the drain plug device of the present invention, an operation portion of a release wire supported by a support member provided on the drain port fitting is attached to the lower surface of the cover and is operated by remote operation.

The drain plug device of the present invention comprises a drain plug composed of a cover that covers the drain port and a packing that stops drainage. Can be obtained. For example, since the cover is in the cylindrical depression of the drain port portion and can move up and down and does not contact the packing, it does not interfere with the pressing water-stopping action of the packing, and the flange portion of the drain port bracket regardless of the function of the cover Can be sealed with water. Further, the position of the cover can be set regardless of the action of sealing water sealing of the packing, and the cover can be easily and easily positioned substantially flush with the bottom surface of the water tank.
Therefore, the drain plug can stop the drainage even with a light contact just by mounting the packing on the flange portion of the drain port fitting, and the cover is substantially flush with the bottom surface of the water tank. It is possible to cover the part and cover the dirt in the drainage port part, and it is possible to look good.

  The drain plug device of the present invention can be easily contacted to the flange portion of the drain fitting by the packing inserted and held in the shaft portion of the lower surface of the cover by the construction in which the operating portion of the release wire is provided on the lower surface of the cover. Sealed water can be stopped by the contact. Therefore, the construction of such a drain plug device can be performed easily and easily.

  A cylindrical depression is formed at the bottom of the aquarium, and a cover is covered with a drainage outlet mounted with a drainage fitting with an inward flange formed on the depression, and a packing provided below the cover. A drain plug device that can raise and lower a drain plug, and shows an open / closed state by raising and lowering the drain plug.

As shown in FIG. 1, the drain plug device of the present invention forms a cylindrical depression 10 in the bottom 1 of a water tank such as a vanity, a bathtub, a sink, etc., and an inward flange 11 is formed at the bottom of the depression. The inward flange portion is formed and sandwiched and attached to the drain port fitting 3 and the connecting pipe 5 via the packing material 4 to constitute the drain port portion 2.
The drain port 2 is provided with a cover 6 that can move up and down in the depression 10 and is generally flush with the bottom 1 of the aquarium. The bottom surface of the cover can be sealed with the drain port fitting 3. A shaft 61 for inserting and holding the packing 7 to be inserted is provided to constitute the drain plug 20.

An operating portion 81 of a release wire 8 is supported by a support member 9 on the drain fitting 3, and the operating portion is attached to the lower surface of the cover 6 via a support shaft 82, and a shaft portion provided on the lower surface of the cover 6. The packing 7 inserted and held in 61 is actuated by remote operation with a release wire 8 to open and close.
A guide cylinder 62 is provided on the lower surface of the cover 6, and the guide cylinder is guided by the release wire operating portion 81 to raise and lower the drain plug 20.

The drain port metal fitting 3 is configured such that the inward flange portion 11 of the cylindrical depression 10 is clamped and attached to the connection pipe 5 so as not to be exposed to the bottom 1 of the water tank, and the drain port fitting 3 is attached to the depression 10. The portion 2 is provided with the cover 6 of the drain plug 20 in the cylindrical depression 10 so as to be movable up and down, so that the drain port 2 is covered, and is caused by residual water or scale generated at the attachment boundary of the drain port fitting 3 or the like. Dirt etc. are hidden and convenient.
Further, since the cover 6 is provided so as to be movable up and down in the cylindrical depression 10 regardless of the sealing action of the packing 7 provided for water stop, the position setting can be easily and easily performed. In order to prevent the cover from being tripped, the position of the edge of the depressed portion 10 and the edge of the cover 6 may be substantially matched so that the top surface 60 of the cover is substantially flush with the bottom surface 1 of the water tank.

  The packing 7 inserted and held in the shaft cylinder 61 provided on the lower surface of the cover 6 is not in contact with the recessed portion 10 which is difficult to be elaborate in the molding process, but in contact with the drainage fitting 3 which is easy to perform elaborate processing. Therefore, it is possible to obtain a watertight seal accurately and reliably, which is advantageous. Moreover, since the airtightness is good, it is possible to stop the water just by placing the drain plug 20 on the drain outlet fitting 3, and further, the effect is improved if the packing 7 that is sealed by line contact is used.
