工性が一層向上する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin drainage basin with a U trap used for a sewer pipe. 2. Description of the Related Art As a conventional drainage basin with a U-trap, the one described in Japanese Utility Model Laid-Open No. 9-11 is known. The drainage basin described in the above publication comprises a main body and a U trap, a main flow groove is formed at the bottom of the main body provided with an inspection tube receiving portion at the upper end, and an upstream end and a downstream end of the main flow groove are provided on the left and right sides of the main body. A pair of main pipe receptacles that communicate with the main body are inserted, a trap connection port is further inserted into the lower side of the main body, the trap connection port and the main flow groove are connected by an overflow groove, and a joint is connected to the trap connection port. A U trap having a diameter smaller than the diameter of the trap connection port is connected to the main body so as to be able to swing freely. [0003] The above drainage basin is connected to an upstream residential drainage main pipe and a downstream drainage main pipe to a main pipe receiving portion, respectively, and is connected to a U trap connected to a trap connection port via a pipe joint. A branch pipe is connected, a check pipe is connected to the check pipe socket, and the upper end of the check pipe is opened to the ground and closed by a lid to perform piping. However, in the above-mentioned conventional drainage basin, since a joint is provided between the trap connection port and the U trap, a U trap having a small diameter can be connected. Since the joint shaft center connected to the side and the joint shaft center connected to the trap connection port are formed coaxially, there is a limit in increasing the swing angle of the U trap. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to attach a U-trap having a diameter smaller than the diameter of the trap connection port, and at the same time, to attach a U-trap to the neck of the U-trap. An object of the present invention is to provide a drainage basin capable of further increasing the swing angle. SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and the drainage basin of the present invention comprises a main body and a U trap, and has a check tube receiving member at an upper end. A main flow groove is formed at the bottom of the main body provided with the mouth, and a pair of main pipe receiving portions communicating with the upstream end and the downstream end of the main flow groove are protruded to the left and right of the main body, and further, the lower side of the main body is formed. The trap connection port is inserted into the trap connection port, the trap connection port and the main flow groove are connected by the overflow groove, and a U trap having a diameter smaller than the diameter of the trap connection port is swung with respect to the main body through the joint. In the freely connected drainage basin, the joint axis of the side connected to the U trap outlet side is eccentric from the joint axis of the side connected to the trap connection port, and the axis of the trap connection port and the U trap By increasing the distance from the inflow side axis, The swing angle of the U trap is increased. In the drainage basin of the present invention, since the U trap having a diameter smaller than the diameter of the trap connection port is connected to the trap connection port via a joint, the shape of the trap connection port can be changed. A small U-trap can be attached. At the same time, the joint shaft center on the side connected to the U trap outflow side is
By decentering from the joint axis on the side connected to the trap connection port and increasing the distance between the axis of the trap connection port and the axis of the U trap inflow side, the swing angle of the U trap can be reduced by the conventional drainage. Since it can be even larger than a basin,
Workability is improved. 1 to 3 show an embodiment of the present invention. FIG. 1 is a longitudinal sectional view of a drainage basin, FIG. 2 is a plan view of a drainage basin, and FIG. FIG. 2 is an enlarged partial cross-sectional view showing a joint mounting portion of FIG. 1. In the figure, 1 is a drainage basin, 2 is a main body, 3
Is a U trap, and 4 is a joint. The drainage basin 1 of this embodiment is made of a hard vinyl chloride resin, and comprises a main body 2 and a U trap 3. An inspection tube receiving portion 21 is provided at an upper end of the main body 2, and a bottom portion of the main body 2 is provided. The main flow groove 22 is formed in the main flow path. On the left and right sides of the main body 2, a pair of main pipe receiving portions 23 and 24 communicating with the upstream end and the downstream end of the main flow groove 22 are inserted, and a trap connection port 25 is inserted below the main body 2. Have been. The trap connection port 25 and the main flow groove 22 are connected by an overflow groove 26,
A U trap 3 having a smaller diameter than the diameter of the trap connection port 25 is swingably connected to the main body 2 via the joint 4 at the trap connection port 25. As shown in FIGS. 1 and 2, the drainage basin 1 has a joint shaft center J on the side connected to the U trap outlet side 31.
1 is the joint shaft center J on the side connected to the trap connection port 25.
2, the swing angle K of the U trap 3 is increased by increasing the distance L2 between the axis J2 of the trap connection port 25 and the axis J3 on the inflow side of the U trap by deviating from the center 2 by a distance ΔL. . L1 is the inflow side 3 of the U trap 3.
2 is the distance between the axis J3 of the second and the axis J1 of the outflow side 31. One side of the joint 4 is, as shown in FIG.
A groove 41 is formed at the upper end of the outer peripheral surface, and a waterproof packing 42 is attached below the groove 41. The concave groove 41 is formed in a shape that corresponds to a protrusion 251 provided on the inner peripheral surface of the U trap connection port 25, and one side of the joint 4 is
5, the protrusion 251 is forcibly fitted into the groove 41. The other end of the joint 4 is formed as a receiving port, and a projection 43 is formed on an inner peripheral surface thereof. The projection 43 is fitted into a concave groove 33 formed on the outer peripheral surface of the outflow side 31 of the U trap 3 to prevent the U trap 3 from coming off.
The U trap 3 can be swung freely. Further, a waterproof packing 34 is attached below the concave groove 33. The drainage basin 1 is provided with main port receiving portions 23 and 24.
And a drain pipe in the residential land on the upstream side and a drain pipe on the downstream side, respectively, and a branch pipe connected to the U trap 3 connected to the trap connection port 25 via the joint 4 by a pipe joint. An inspection tube is connected to the mouth portion 21, and the upper end of the inspection tube is opened to the ground and closed with a lid for use. As described above, the drainage basin 1 of this embodiment is
The trap connection port 2 is connected to the trap connection port 25 via the joint 4.
Since the U-trap 3 having a diameter smaller than the diameter of No. 5 is connected, the U-trap 3 having a small diameter can be attached without changing the shape of the trap connection port 25. At the same time, U
The joint shaft core J1 on the side connected to the trap outlet side 31 is
It is eccentric by ΔL from the joint axis J2 on the side connected to the trap connection port 25, and the axis J2 of the trap connection port 25 and U
By increasing the distance L2 from the trap inflow side axis J3 by ΔL, the swing angle K of the U trap can be further increased as compared with the conventional drainage basin, thereby improving workability. According to the drainage basin of the present invention, the swing angle of the U trap can be further increased as compared with the conventional drainage basin in which a joint having the same axis is interposed. Workability is further improved.
