Description

[Detailed Description of the Invention] The present invention relates to an odor-preventing ring in which a long cylindrical vinyl is disposed in a streamer-like manner in a wastewater pipe connected to a wastewater basin to prevent the emission of strange odors from the wastewater pipe.

Conventionally, deodorizing rings installed at the connection between sewage basins or rainwater basins and drainage pipes have been used, for example, in the "Jikko 54
-28310 Publication”. As shown in FIG. 4, the deodorizing ring 40 is made up of a ring 41 with a flange and a cylinder 43 that is detachably fixed to a drain pipe 42. The angle formed by the axis of the drain pipe 42 can only be changed by a small amount, and therefore, as shown in FIG. 4, the connection angle between the basin 44 and the drain pipe 42 must be small to be able to be installed. That is, when the drain pipe 42 is connected diagonally to the basin 44, the deodorizing ring 40 cannot be attached.

This invention is an improvement on the conventional deodorizing ring.
The purpose of the present invention is to provide a deodorizing ring that can be easily attached to a sewage basin and a sewage pipe even when the sewage pipe is connected at an arbitrary angle to the sewage basin, and the ring is designed to prevent the inside of the sewage basin from leaking when fluid is passing through. A flange 1 has an opening at one end of a cylindrical body 8 that can be deformed so as to expand, and a mounting body 2 that is detachably fixed in a fluid discharge pipe surrounding the cylindrical body 8. ,
They are characterized in that they are connected to each other by a connecting rod 3 of a required length so that the angles formed by their respective axes can be varied.

The following will be explained based on the embodiment shown in the attached drawings. Fig. 1 shows a side sectional view of the deodorizing ring A, where 1 is a flange, 2 is a flange cut out in the required number of slits in the longitudinal direction, and is inserted into a wastewater pipe. Mounting body to be fixed, 3
is a connecting rod of a required length that connects the flange 1 and the mounting body 2.

In this example, one for a round-shaped box is shown.
Therefore, the flange surface of the flange 1 has a required curvature so as to approximately match the curvature of the inner circumference of the cell.
It is molded from ABS resin, etc., and has an annular recess 4.
The rubber gasket 5 is installed in the annular recess. As shown in FIGS. 1 and 2, one end of the connecting rod 3 is rotatably attached to the flange 1 via a fastener consisting of a bolt 6a and a nut 6b, and the other end is attached to the mounting body 2. It is likewise pivotably mounted on the projection 7, so that the mounting body 2 can be tilted relative to the flange 1, as can be seen in FIG. Length of connecting rod 3 (strictly speaking, bolt-nut 6a, 6
b) and the distance between the protrusion 7) in the annular recess 4 of the flange 1.
If the radius is longer than the radius of the flange, the upper end 2a of the mounting body 2 will not come into contact with the flange, and since the bolt-nut 6a, 6b positions are shifted downward from the lower surface 1a of the flange 1, the connecting rod 3 The rotation angle is 180° or more, so that the mounting body 2 can be sufficiently inclined with respect to the flange 1. Furthermore, since the mounting body 2 is also rotatable with respect to the connecting rod 3, the angle between the 1 axis of the flange and the axis of the mounting body 2 can be set arbitrarily.

The mounting body 2 is integrally molded using elastic material such as polyethylene, and has an annular base 2 at the upper end.
Several extension parts 2c are formed in a strip shape so as to expand in the radial direction at a required circumferential pitch from b, and further extend in the axial direction for a required length from the end of each extension part 2c, and the outer peripheral surface is connected to the wastewater pipe P. A contact portion 2d is provided as a contact surface with the inner surface of the contact portion 2d. Therefore, the outer diameter D ₀ of the contact portion 2d
Since the mounting body 2 has elasticity and the space between adjacent extension parts is cut out in a slit shape, if each contact part 2d is pressed toward the center of the mounting body 2, the extension part 2c The subsequent portions can be elastically deformed and reduced in diameter.

Further, in FIG. 2, the flange 1 is provided with an opening 1b, and a rivet 20 is pushed through the opening.
As a result, the cover 21 that closes the sewage pipe connection port opened in the sewage basin is fixed. Figure 5 shows sewage basin 5.
A cross-sectional view is shown in which the deodorizing ring A is placed at the inlet of a wastewater pipe P connected perpendicular to the axis, and as will be described later, the attachment body 2 is inserted into the wastewater pipe P and the extension part 2c is The deodorizing ring A is fixed by the elastic force. M is mortar filled between the sewage pipe connection port J of the sewage basin S and the outer periphery of the sewage pipe P. The cover 21 is curved with approximately the same curvature as the inner circumferential surface of the sewage basin S so that it can be fitted onto the inner circumferential surface of the sewage basin S, and blocks the inside of the sewage basin S and the sewage pipe connection port J as shown in the figure. ing. Therefore, the sewage from the cesspit S can be discharged from the flange 1 of the deodorizing ring A in the direction of the sewage pipe P without leaking to the outside.

Furthermore, a long cylindrical body 8 made of vinyl or polyethylene or the like with openings at both ends is attached to the flange 1 in a windsock manner, and the sewage from the sewage basin is discharged from this cylindrical body 8 into the sewage pipe P. When the water does not pass through, the bag-like structure deflates and the sewage pipe P
The construction is such that no odor is emitted from the tank to the sewage basin.

Fig. 3 shows a cross-sectional view of the deodorizing ring A installed in the wastewater pipe P, and the wastewater pipe P is connected so that its axis is inclined with respect to the wastewater basin S. Since the angles formed by the respective axes of the flange 1 and the mounting body 2 can be freely changed, the arrangement as shown in the drawings is possible. In addition, this installation method is as follows: After pressing each extension part 2c of the mounting body 2 to reduce the diameter of the contact part 2d, the cover 21 is inserted into the wastewater pipe P until it comes into contact with the inner peripheral surface of the wastewater basin S. , the extension portion 2c is subjected to elastic strain, and the abutting portion 2d is pressed against the inner surface of the wastewater pipe P by this elastic repulsion force, thereby fixing the mounting body 2 to the wastewater pipe P.

Therefore, due to the fixation of the deodorizing ring A, the cylindrical body 8 is placed in a streamer state inside the wastewater pipe P, and the emission of strange odors from the wastewater pipe P can be prevented.

As described above, according to the present invention, it is possible to freely change the angle formed by the axes of the flange located in the sewage basin and the mounting body located in the sewage pipe, so that the connection angle between the sewage pipe and the sewage basin can be adjusted. The effect is that the deodorizing ring can be reliably provided regardless of the situation.
