Description

  The present invention relates to a drainage drain having a rotating trap and a rotating leg.

Conventionally, as a drain with a rotating trap, a small-diameter trap receiving port is formed at the bottom of a small-diameter mast to insert a U-trap trap insertion port in a freely rotatable manner. The receiving port and the inserting port There is provided a trap that allows the U-trap to always rotate with respect to the small diameter by interposing an O-ring sandwiched between bushes provided in the vertical direction between them (see Patent Document 1). ).
Conventionally, as a drop trough with a trap, a dredging for use in a residential land or the like in which a drop tube receptacle is formed in the lower part of the dredge body and a U-shaped trap is attached to the drop pipe receptacle has been provided (Patent Literature). 2).

However, in the above-mentioned conventional trap, a drainage main receptacle is formed in the center of the bottom of the small caliber, that is, on the side of the U trap, and the drainage main is inserted into the drainage main receptacle. Since the main pipe flow path is formed, even if it is a U trap that can always rotate, the drain main pipe flow path considerably limits the rotation angle of the U trap. However, there is a problem that the desired piping may not be realized. Further, in the above-mentioned trap, in order to improve the workability of the piping construction work, it is conceivable to provide a leg portion at the lower part of the drain main pipe receptacle. However, there is a problem in that the degree of freedom of piping may be further reduced.
In addition, since the above-mentioned conventional housing lots are not provided with legs at the bottom of the rod body, the posture of the rod is not stable when piping work is performed, and the workability of the piping work may be reduced. There was a problem that there was.

As a means for solving the above-mentioned conventional problems, the present invention has a main body 2 having a drain pipe connection port 3, an inspection cleaning port 4, and a trap connection port 5, and one end of the trap connection port 5 of the main body 2. In the drainage drain provided with a rotating trap 14 that is rotatably attached, a rotating leg 6 that supports the main body 2 is rotatably attached to the main body 2 , and the rotating trap 14 and the rotating leg are supported. The part 6 provides a drain 1 which is adapted to rotate together.
The central axis X at one end of the rotary trap 14 is preferably set at a position eccentric from the central axis Y of the trap connection port 5 in the direction in which the rotation angle θ of the rotary trap 14 increases.
Further, it is desirable that a rotary elbow 18 is rotatably attached to the other end of the rotary trap 14.
Further, it is desirable that the main body is a drop 2.

In the drainage basin 1 of the present invention, the rotary trap 14 attached to the main body 2 and the rotary leg 6 are rotated together.
The rotation angle θ is not limited, and the rotation range of the rotary trap 14 can be secured widely. Therefore, the degree of freedom of piping is improved, and a desired piping can be realized.
Further, in the drainage basin 1 of the present invention, the main body 2 can be supported by the rotating legs 6 attached to the main body 2, so that the posture of the drainage basin 1 can be stabilized when performing piping construction work. It is possible to improve workability of piping construction work.

It is attached so that it can rotate freely.
In the present embodiment, a sealing rubber ring 11 is interposed between the outer peripheral surface of the trap connection port 5 and the inner peripheral surface of the upper receiving port 8 of the eccentric joint portion 7. Inside the drop trough 2, a cleaning eye plate 12 is fitted into the trap connection port 5 from above (see FIGS. 1 and 5).

One end of a U-shaped rotary trap 14 is inserted and fixed to the lower eccentric receiving port 13 of the eccentric joint portion 7 of the rotary leg 6, and one end of the rotary trap 14 is fixed to the rotary leg portion. It is rotatably attached to the trap connecting port 5 of the drop 2 through an eccentric joint portion 7 of 6. In this way, the rotary trap 14 and the rotary leg 6 rotate together.
In the present embodiment, the central axis X at one end of the rotary trap 14 is in the direction in which the rotation angle θ of the rotary trap 14 increases, that is, in the direction opposite to the drain pipe connection port 3. 5 is set at a position eccentric from the central axis Y (see FIGS. 1, 2 and 6).

The rotating leg 6 is provided with a pair of left and right support legs 15. A notch 16 is provided in front of and behind the rotating leg 6, and the rotating leg 6 has a substantially U shape when viewed from the front (see FIGS. 3 and 4).
The substantially half of one end of the rotary trap 14 connected to the eccentric joint part 7 of the rotary leg 6 is in a state of being accommodated between the pair of left and right support legs 15 of the rotary leg 6. In addition, substantially half of the other end of the rotary trap 14 protrudes from the notch 16 of the rotary leg 6 (see FIGS. 1 and 2).
In this embodiment, a support leg 17 for supporting the rotary trap 14 is provided below the rotary trap 14.

A rotating elbow 18 is attached to the other end of the rotating trap 14. An annular locking rib 19 is provided on the outer peripheral surface of the other end of the rotating trap 14, while an annular locking claw 21 is provided at the receiving port 20 at one end of the rotating elbow 18. The locking claw 21 of the rotating elbow 18 is locked to the locking rib 19 of the rotating trap 14, so that one end of the rotating elbow 18 is rotatably attached to the other end of the rotating trap 14.
In this embodiment, the outer peripheral surface of the other end of the rotary trap 14 and the inner end of the rotary elbow 18
A sealing rubber ring 22 is interposed between the peripheral surface and a downstream drain pipe (not shown) is connected to the receiving port 23 at the other end of the rotating elbow 18. .

  In the case of piping construction using the drainage trough 1 as shown in FIG. 7, according to the piping layout, the rotary trap 14 and the rotary leg 6 are rotated together with respect to the drop trough 2, The rotary elbow 18 is rotated with respect to the rotary trap 14, the orientation of the drain pipe connection port 3 and the rotary elbow 18 is adjusted, the upstream drain pipe is connected to the drain pipe connection port 3, and the rotary elbow A downstream drain pipe is connected to the other end of 18.

As described above, in the drainage drain 1 of this embodiment, the rotary trap 14 and the rotary leg 6 attached to the lower part of the drop trough 2 are rotated together. The rotation angle θ of the rotary trap 14 is not limited, and a wide rotation range of the rotary trap 14 can be secured. Therefore, the degree of freedom of piping is improved, and a desired pipe can be realized. It becomes.
Further, in the drainage basin 1 of this embodiment, the drop basin 2 can be supported by the support leg 15 of the rotary leg 6 attached to the lower part of the drop basin 2 and provided at the lower part of the rotary trap 14. Since the rotation trap 14 can be supported by the support leg 17, the posture of the drainage 1 can be stabilized when the piping construction work is performed, and the workability of the piping construction work can be improved.

  In the present embodiment, the central axis X at one end of the rotary trap 14 is set at a position that is eccentric from the central axis Y of the trap connection port 5 in the direction in which the rotational angle θ of the rotary trap 14 increases. A wider rotation range of the rotary trap 14 can be secured, so that the degree of freedom of piping can be further improved, and a desired piping can be reliably realized.

  Further, in this embodiment, since the rotary elbow 18 is rotatably attached to the other end of the rotary trap 14, the rotary trap 14 is rotated with respect to the drop 2 and the rotary elbow 18 is rotated. By rotating with respect to the other end of the trap 14 (see FIG. 7), the degree of freedom of piping can be further improved, and a desired piping can be realized more reliably.

  Furthermore, in this embodiment, the main body is the drop 2, the drain pipe connection port 3 is provided at the side of the drop 2, and the trap connection port 5 is provided at the lower part of the drop 2. The rotation angle θ of the rotary trap 14 is not so limited by the drain pipe connection port 3.
