つ適切に接続することができる。 In the drain plug device configured as described above, when connecting the cap 3 to the end of the pipe 2, the sleeve 5, which has seal lips 7, 7 attached to the outer circumferential surface,
is inserted into the end of the pipe 2 to bring the flange 4 into contact with the end surface of the pipe 2. Then, the tips of the seal lips 7, 7 attached to the sleeve 5 (lip 7a)
is pressed against the inner circumferential surface of the pipe 2, so the cap 3 can be connected to the end (open end) of the pipe 2 in a watertight manner. still,
In order to improve the sealing performance of the connection part, the lip 7 of the sealing lips 7, 7 as shown in FIG.
It is desirable to fill the inside of a with a suitable caulking material 17. In addition, since the outer diameter of the sleeve 5 is sufficiently smaller than the inner diameter of the pipe 2 to form a ring-shaped gap 6 between the two, the sleeve 5 (insertion metal fittings) can be freely tilted within the pipe 2. Therefore, even if the bottom surface 1 and the pipe 2 are not perpendicular to each other, the insertion fitting can be connected without causing any particular difficulty. Further, a plurality of seal lips 7, 7 are provided on the outer periphery of the sleeve 5, and the tip of the seal lip 7 located relatively downward can be superimposed on the base of the seal lip 7 located relatively upward. At the same time, since the overlapping thickness of the tip and base of the seal lip 7 is equal to or greater than the thickness of the gap 6, even if the sleeve 5 is tilted significantly, the tip of the seal lip 7 will not disturb the inside of the pipe. It is pressed against the peripheral surface to ensure sealing performance. Therefore, even if the bottom surface 1 is inclined to improve drainage, the cap 3 can be easily and appropriately connected to the end of the pipe 2.

く傾斜することを防止できる。 Further, since the seating surface of the drain port 10 is constituted by an O-ring 11, even if a large water pressure is applied to the drain plug 12, the drain plug 12 will not be fixed to the base 3. For this reason, the drain plug 12 can be removed extremely easily when draining water. Furthermore, since the seating surface 14 of the drain plug 12 is formed with a spherical surface, even if the drain plug 12 is inclined, the seating surface 14 can be securely attached to the seating surface (O-ring 11) of the drain port 10. closely adhere to. Therefore,
Not only the ease of removing the drain plug 12 but also the workability of installing it can be improved. In addition, drain port 10
Since the seating surface of the drain plug 12 is formed by the O-ring 11, the O-ring 11 deforms following the seating surface 14 of the drain plug 12, so that the watertightness of the drain plug 12 becomes high. Further, since a guide 13 is provided on the back side of the drain plug 12, the guide 13 can easily guide the drain plug 12 to the drain port 10, and the guide 13 and the inner surface of the drain port 10 can be easily guided. This engagement action prevents the drain plug 12 from tilting more than necessary.
尚、実施例では配管に対して口金を傾斜状態で
接続できるようにしているが、この口金の具体構

きる。<Effects of the invention> As explained above, according to the invention, it is possible to install the drain plug in a watertight manner by simply dropping it into the drain outlet, and the structure is such that the drain plug and the fitting do not come into direct contact with each other. Since the drain plug can be easily removed, the workability of attaching and removing the drain plug can be greatly improved without impairing watertightness.
