Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an adjuster cylinder body fitted and connected to an upper edge of a drainage mass main body used for sewerage.

(Prior art) When connecting a drainage pipe directly to the body of the drainage mass, which is generally used in the past, or when fitting the adjuster cylinder to the body of the drainage mass to adjust the height with the ground surface. In some cases, the drainage pipe is connected to this adjuster cylinder.

Normally, a socket for connecting the drainage pipe is integrally projected on the drainage mass body, but the adjuster cylinder is simply formed with a punching groove, which is used when connecting the drainage pipe. The punching groove is punched and a drainage pipe is inserted.

An example of such a structure is, for example, Jpn.
There are drainage masses described in Japanese Patent No. 261 and Japanese Utility Model Publication No. 61-45264.

As shown in FIG. 5, the former is such that a punching groove 15 is preliminarily formed on the peripheral wall 13 of the adjuster cylinder 11 which is fitted and connected to the drainage mass main body 10 in accordance with the shape of the drainage pipe to be connected. Plural pieces are engraved in a mutually shifted manner so as to form the portion 17.

To connect the drainage pipe, the punching groove 15 at an appropriate position may be punched with a hammer or the like, and then the drainage pipe may be fitted. When a plurality of punched grooves 15 are formed in the vertical direction as in this known example, the height position of the drainage pipe can be variously changed and connected.

As shown in FIG. 6, the latter is composed of an adjuster cylinder 19 fitted and connected to the drainage mass main body 17, and a knockout hole 20 is formed on the peripheral surface of the adjuster cylinder 19. Then, the position of the knockout hole 20 may be adjusted and opened so as to match the drainage pipe of the rain trough, and the drainage pipe may be inserted into this opening.

In each of the known examples, fitting drainage grooves 21 and 23 are formed at the upper ends of the drainage mass body and the adjuster barrel body, and the fitting ring grooves 21 and 23 are respectively provided with the adjuster barrel body 11 and the adjuster barrel body. 19 is fitted and connected, or a lid is fitted.

(Problems to be Solved by the Invention) However, the above configuration has the following problems.

That is, the punching groove 15 or the knockout hole 20 engraved on the peripheral surface of the adjuster cylinder 11 and the adjuster cylinder 19 is,
If both are punched out and the drainage pipe is inserted,
The thickness of the peripheral wall of the adjuster cylinder only holds the drainage pipe. Moreover, in the past, the adjuster cylinder was made of expanded polypropylene resin, whereas the drainage pipe was made of vinyl chloride resin, so it was not possible to connect both by adhesive. Therefore, since the drainage pipe is merely fitted into the opening, the holding force is weak and there is a risk of falling off, and the watertightness is poor and water leakage cannot be prevented.

Further, the fitting annular grooves 21 provided on the upper end edges of the drainage mass body 10 and the adjuster cylinder 11, respectively, and the fitting annular grooves 23 provided on the upper end edges of the drainage mass body 17 and the adjuster cylinder 19 respectively. In each case, the side surface of the annular groove is formed vertically and an insertion clearance is provided. Therefore, just by inserting the lower part of the peripheral wall of the adjuster cylinder into the fitting annular grooves 21 and 23, the water blocking performance is not sufficient, and rainwater, earth and sand, etc. flow into the main body 1 and the adjuster cylinder 3 from the connecting portion of both. . In addition, the inflow of rainwater and earth and sand is enormous, which greatly increases the amount of wastewater to be treated and puts pressure on the treatment capacity at the treatment plant.

The present invention has been made in view of the problems of the conventional technique, and the purpose thereof is to easily and surely insert a drainage pipe,
It is intended to provide an adjuster cylinder body for a drainage mass which is excellent in waterproofness.

(Means for Solving the Problem) Therefore, the drainage mass in this invention has the following configuration.

That is, in the drainage mass adjuster cylinder body which is fitted and connected to the annular groove of the drainage mass main body in which the fitting annular groove is provided all around the upper end edge, the inner diameter wall and the inner diameter are provided all around the upper end edge of the peripheral wall. A fitting annular groove is formed by an outer diameter wall having a height higher than that of the wall, and the entire inner surface of the outer diameter wall forming the groove is gradually reduced in diameter from the upper end to the lower end so that the crucible moves downward. On the other hand, the outer surface of the lower portion of the peripheral wall is made to have an inclined surface having substantially the same diameter and inclination angle as the inner surface of the outer diameter wall, and two or more horizontal annular projections are formed in a step shape. A connection port pipe reinforced by a reinforcing rib is provided, and the peripheral wall portion surrounded by the connection port pipe is made thin, or an annular punching groove is formed along the inner surface of the connection port pipe. Characterize.

(Operation) In the drainage mass adjuster cylinder having the above-described configuration, the inner surface of the outer diameter wall forming the fitting annular groove is an inclined surface, and the outer surface of the lower portion of the peripheral wall is an inclined surface having substantially the same diameter and inclination angle as the inclined surface. Therefore, the fitting and connection can be easily performed, and the water tightness is improved by the close fitting without providing the insertion clearance. Further, the connection port pipe provided at an appropriate position on the peripheral wall reliably holds the drainage pipe and prevents water leakage.

(Example) Next, the adjuster cylinder for drainage mass according to the present invention will be described in detail based on an example.

1 is a front view in which the right half is sectioned, FIG. 2 is a plan view,
FIG. 3 is a side view, and FIG. 4 is a partially sectional front view showing a usage state.

An annular groove 31 for fitting is provided all around the upper edge of the peripheral wall 30. The fitting annular groove 31 includes an inner diameter wall 33 and the inner surface wall 33.
A slant which is formed by an outer diameter wall 35 having a height higher than that of the outer diameter wall 35 forming the groove, and the entire inner surface 37 of the outer diameter wall 35 is gradually reduced in diameter from the upper end to the lower end so as to be downwardly inclined. It is regarded as a face.

Further, since the lower portion of the peripheral wall 30 is fitted and connected to the fitting annular grooves of the drainage mass main body and the adjuster cylinder located at the lower stage when fitted and connected, the lower outer surface 39 forms the fitting annular groove 31. The outer diameter wall 35 has an inclined surface having substantially the same diameter and inclination angle as the inner surface 37. Therefore, the lower outer surface
The inner surface 39 of the outer diameter wall 35 is an inclined surface that inclines downward and inward.

Thus, by making the inner surface 37 of the outer diameter wall 35 and the lower outer surface 39 be inclined surfaces having the same diameter and inclination angle, not only the fitting is facilitated without providing an insertion clearance, but also the inclined surface. Comrades are in close contact with each other, and water stopping ability can be improved.

Further, when two or more annular projections are formed in a step shape on the lower outer surface 39, the inner surface 37 of the outer diameter wall 35 when fitted and connected.
The adhesive work and the sealant are held, and the application work is facilitated.

Further, in this invention, the connection port pipes 41 are provided on the outer surface of the peripheral wall 30 so as to be 180 degrees apart from each other. The connection pipe 41
Is reinforced by two reinforcing ribs 43 which are parallel to each other in the vertical and horizontal directions. The peripheral wall portion 45 surrounded by the connection port pipe 41 is formed thin so as to facilitate opening, and a hole saw positioning recess 47 is provided at the center position.

In addition to the above embodiment, an annular punching groove may be formed in the peripheral wall portion 45 along the inner surface of the connection port pipe 41 in order to facilitate punching with a hammering force or the like.

Further, as shown in the drawing, a spiral projection 49 may be provided on the inner surface of the connection port pipe 41. The provision of the spiral projection 49 is effective in preventing the drainage pipe press-fitted from coming off and preventing water leakage.

In the above embodiment, the number of connection port pipes 41 can be changed appropriately. Further, the shape of the adjuster cylinder is not limited to the above-mentioned embodiment, but can be applied to various shapes.

The drainage mass body to which the adjuster cylinder is connected has the lower end portion of the adjuster cylinder fitted and connected to the upper end edge thereof. Therefore, a fitting annular groove is formed at the upper edge of the drainage mass body so that the lower end of the adjuster cylinder can be fitted. The fitting annular groove of the drainage mass body is preferably formed in the same shape and size as the fitting annular groove of the adjuster cylinder. That is, the fitting annular groove is formed by the inner diameter wall and the outer diameter wall having a height higher than that of the inner diameter wall, and the entire inner surface of the outer diameter wall is gradually reduced in diameter from the upper end to the lower end. It is preferably formed by inclining so as to bulge toward it.

The following effects can be obtained in the above embodiment.

That is, the inner surface 37 of the outer diameter wall 35 forming the fitting annular groove 31 is an inclined surface, and the lower peripheral wall outer surface 39 is also the inner surface 37 of the outer diameter wall 35.
Since the inclined surface has the same diameter and the same inclination angle as the above, the connecting work is easy, and the waterproof property is maintained by the close contact of the inclined surfaces.

When two or more horizontal annular projections are provided on the outer surface 39 of the lower portion of the peripheral wall, the inner surface 37 of the outer diameter wall 35 is brought into close contact with the outer surface 39 to enhance the water blocking property, and the work of applying an adhesive or a sealant is facilitated.

In addition, the drainage pipe to be connected is a connection port pipe 41
Since it is press-fitted into, it is firmly connected and there is no risk of falling off, and it is also highly watertight and can prevent water leakage.

Further, since the peripheral wall portion 45 surrounded by the connection port pipe 41 is formed thin, it can be easily opened. On the other hand, the peripheral wall portion 45 is a connection port pipe although it is formed thinly.
Since it is surrounded by 41, it does not open accidentally.

(Effect of the Invention) Since the present invention has the connection port pipe provided on the outer surface of the peripheral wall, the drainage pipe can be easily and surely inserted and the press-fitted drainage pipe can be closely fitted with the connection port pipe. Water leakage can be prevented. In addition, the inner surface of the outer diameter wall and the outer surface of the lower peripheral wall not only facilitate fitting connection, but also
Excellent watertightness to prevent water leakage. In addition, the horizontal annular projection on the outer surface of the lower part of the peripheral wall facilitates the application work of adhesives and sealants, enhances the waterproof performance, and facilitates the mating connection with the drainage mass body and the mating connection between the adjuster cylinders.
