BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a universal pipe connecting portion of a drainage basin arranged at a confluence of sewage pipes.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, a drainage tub (1) is provided with an inspection tube connecting part (3) at the upper part of the main body (2), and a pipe connecting part (4) and a free pipe are provided on the side. A configuration is provided with a connection (5).

The universal pipe connecting portion (5) is enlarged in diameter all around the root, and the connected pipe (7) is the universal pipe connecting portion (5).
Packing ring fitted in the packing mounting groove (5A) of
It can be rotated left and right and up and down with (6) as a fulcrum, and the connection angle can be freely adjusted left and right and up and down.

[0004]

However, in the above-mentioned conventional structure, as shown in FIG. 6, when the pipe (7) is connected to the universal pipe connecting portion (5) from diagonally above, the universal pipe connection is performed. Part (5) has a problem in that a pool A is formed at the bottom, and dust or mud accumulates in the pool A, increasing the frequency of cleaning work.

[0005]

[Means for Solving the Problems] As a means for solving the above-mentioned conventional problems, the present invention is a universal pipe connecting portion (16) provided on the side surface of a drainage basin (11) main body (12), which extends to the root portion. The purpose of the present invention is to provide a universal pipe connecting part (16) of a drainage basin (11) whose diameter is expanded only in the horizontal direction.

[0006]

[Function] Since the universal pipe connecting part (16) provided on the side surface of the main body (12) of the drainage basin (11) is expanded only in the horizontal direction toward the root part, it is connected to the universal pipe connecting part (16). Since the pipe is prevented from rotating in the vertical direction and can rotate only in the horizontal plane, the connection angle cannot be adjusted in the vertical direction, and the connection angle can be adjusted only in the horizontal direction.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 5, in which an inspection tube connecting portion (13) is provided on an upper portion of a main body (12) of a drainage basin (11) and side portions thereof are provided. The main pipe connecting portion (14) and the branch pipe connecting portion (15) are provided, and the universal pipe connecting portion (16) is further provided. As shown in FIG. 5, the universal pipe connecting portion (16) is expanded in the horizontal direction only toward the root, and is provided with a packing mounting groove (16A) for mounting the packing ring (17).

In the above-mentioned configuration, the inspection pipe (18) is connected to the inspection pipe connection part (13) of the drainage basin (11), and the sewer pipe is connected to the main pipe connection part (14) and the universal pipe connection part (16). The pipes (19, 20) are connected, and the sewer branch pipe (21) is connected to the branch pipe connection part (15), but the universal pipe connection part (16) is expanded only in the horizontal direction toward the root part. since, sewer main pipe (20) as shown in FIG. 3 dashed line in right and left (20
The connection angle can be adjusted by rotating in the range shown in A, 20B) . However, as shown in FIG. 4, since the sewage main pipe (20) is prevented from rotating up and down, the bottom pool portion of the universal pipe connecting portion (16) is not formed.

[0009]

[Effects of the Invention] Therefore, according to the present invention, a pool portion is not formed in the free pipe connection portion of the drainage basin , dust and mud accumulate in the pool, and the water is smoothly joined to and discharged from the drainage basin.
Also, the frequency of cleaning work is reduced.
