DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small cell, and more particularly to a small cell used for, for example, a house cell for drainage facilities in a house or a public cell for sewerage.

[0002]

2. Description of the Related Art Referring to FIG. 6, a conventional small container 1 includes a main body 2, which has an inlet 3 connected to an inflow side pipe and a flow connected to an outflow side pipe. An inspection port 5 communicating with the ground via the outlet 4 and the riser pipe is integrally formed.

[0003]

In the conventional small basin 1,
Since the position of the inflow port 3 is uniquely regulated by fixing the main body 2, for example, as shown in FIG. If it does not coincide with the axial center 8, the deviation must be absorbed through another member such as the eccentric socket 9 and the workability is poor. On the other hand, actual development Sho 58-16508
No. 6 has a lid attached to the inlet to the inlet
Eccentric socket is provided, and the cover is rotated
Adjust the position of the mouth so that the inlet axis and the inflow
Disclosed is a configuration that absorbs the deviation from the axis of the side conduit.
Have been. According to this conventional technique, an eccentric socket etc.
Although it can absorb the misalignment of the shaft center without using it,
Since it is necessary to use a tightening screw ring for fixing,
There was a problem that the workability was poor.

Therefore, a main object of the present invention is to provide a small sized basin capable of improving workability.

[0005]

Means for Solving the Problems] The present invention, inlet, outlet and Masumoto body having an inspection opening, a flange formed on the outer periphery of the inlet fitting fitted forced the flange rotation capable sealing the gap between the short pipe, and the flange and the fitting portion which have a shaft center which is eccentric with respect to part the inlet of the axis and a receptacle for receiving a tube
It is a small box with a seal ring .

[0006]

When the short pipe attached to the inflow port is rotated , the axial center of the receiving port moves around the axial center of the inflow port on the circumference corresponding to the deviation of the axial center. Therefore, rotate the short tube
Only then, the position of the socket can be adjusted appropriately. It also fits on the tsuba
So that the parts are rotatably forcibly fitted through a seal ring
Since a short pipe is attached to the inlet, another
It is not necessary to use the mounting member of.

According to the present invention, it is possible to absorb the offset (offset) of the axial center of the inflow side pipe line without using a separate member such as an eccentric socket as in the prior art, and moreover, to attach the short pipe to the inflow port. Since it is not necessary to use a separate mounting member, workability can be dramatically improved. Also rotate the short tube
You can easily adjust the position of the inlet port by simply doing
Even when a step difference of a predetermined amount or more is required between the inflow side and the outflow side to completely prevent the backflow, it is possible to cope with it very simply by rotating the short pipe. Further, since the fitting portion is forcibly fitted to the collar, the short pipe does not come off from the inflow port.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 4, a small container 10 of this embodiment includes a main body 12 made of a synthetic resin such as vinyl chloride. At the top of the main body 12, the rising pipe 1 is provided on the inner surface thereof.
Inspection port 18 having receiving port 16 for receiving the pipe end 4 (FIG. 5)
Are formed, and an outlet 20 and an inlet 22 are formed on the left and right of the main body 12, respectively. In addition, legs 24 for stabilizing the small rod 10 are formed on the bottom of the main body 12. Further, as shown in FIG. 4, a flange 26 is formed on the outer periphery of the end of the inflow port 22 by expanding the diameter in two steps, and a seal ring 30 is attached to the step portion 28.

A short pipe 32 is rotatably connected to the inlet 22 by, for example, "forced insertion" or "forced fitting". The short pipe 32 has an inflow side conduit 34 on its inner surface.
A pipe line portion 38 having a receiving port 36 for receiving the pipe end (FIG. 5) and having an inner diameter smaller than the inner diameter of the inflow port 22 is included. At the outer periphery of the end portion of the pipe path portion 38 on the connection side, a disc portion 44 (in which the outer diameter is slightly larger than the outer diameter of the inflow port 22 and the axis 40 thereof is eccentric from the axis 42 of the receiving port 36 by a distance L 3) is formed. Further, a substantially triangular reinforcing rib 46 is formed perpendicularly to and integrally with both the side surface of the conduit portion 38 and the main surface of the disc portion 44. A fitting portion 48 (FIG. 4) having a substantially U-shaped cross section is formed on the peripheral edge of the disc portion 44, and the fitting portion 48 is forcibly fitted to the outside of the collar 26. Therefore, the axis 40 of the disc portion 44 and the axis 50 of the inflow port 22 coincide with each other. When the short pipe 32 is rotated, the shaft center 42 of the receiving port 36 has a circumference 52 with a radius L centered on the shaft center 50 of the inflow port 22 as shown by the alternate long and short dash line in FIG.
Move up.

Referring to FIG. 5, such a small rod 10 is installed in the ground, and the rising pipe 1 is installed at the inspection port 18 (reception port 16).
4, the outflow side pipeline 54 is connected to the outflow port 20, and the inflow side pipeline 34 is connected to the pipeline portion 38 (reception port 36).
Is connected. A lid 56 is provided on the upper end of the rising pipe 14.
Is attached. According to this embodiment, the position of the receiving port 36 (FIG. 1) can be adjusted as appropriate by rotating the short pipe 32. Therefore, for example, as shown by the chain double-dashed line in FIG. Even when 34 is disposed slightly downward, the displacement can be easily absorbed by adjusting the position of the receiving port 36 (FIG. 1). Also, fit on the collar 26
The fitting portion 48 is rotatably forcibly fitted through the seal ring 30.
Therefore, the short pipe 32 is installed in the inflow port 22.
No need to use a separate mounting member to attach
Further, the short pipe 32 does not separate from the inflow port 22.

In the above-described embodiment, an example in which only one set of the inflow port 22 and the short pipe 32 connected to the inflow port 22 is formed, but two or more sets may be formed if necessary.
