Abstract

PURPOSE: To absorb a diametral difference between an adapter and a drainage pipe so as to completely accomplish sealing by screw-fitting box nuts, and pressing a curved longitudinal lip provided on the upper end of the cylindrical main body of the adapter from above. CONSTITUTION: After nox nuts 5, 5 are previously fitted to a drainage pipe 11 from an equipment apparatus such as a wash basin or the like, a drainage pipe 11 is inserted in the inside diameter of an adapter. At this time, a back-up plate 6 is interposed between the box nuts 5 and a flange 9 provided on the upper part of the cylindrical main body 8 of an adapter 8. Subsequently, a screw 4 provided in the inside diameter of the box nut 5 is screw-engaged with a screw 11 provided on the outer periphery of the flange 9 to screw-fit the box nut 5 to the cylindrical main body 8. Whereupon, the box nut 5 presses a curved collar-like longitudinal lip 2 provided on the upper end of the cylindrical main body 8, and the longitudinal lip 2 is brought into close contact with the outer peripheral surface of the drainage pipe 11 to completely accomplish sealing. Even if another U-shaped ring packing 3 is installed instead of the longitudinal lip 2, the same effect can be obtained.

2. Description of the Related Art A soft material adapter is fitted and mounted by pushing the adapter into the inner diameter of a drain pipe that is preliminarily installed on a wall or floor, and then the drain pipe on the equipment side is inserted into the inner diameter of the soft material adapter. Although the two pipes are connected, the drainage pipes of washbasins, hand washbasins, dressing tables, and other living equipment equipment have different diameters, so each is for each diameter. , The diameter of the drainage pipe to be inserted is almost the same as the diameter of the drainage pipe to be sealed, or a simple ring-shaped ridge is provided to accommodate it. I can't do that,
It corresponds individually for each diameter.

The present invention is intended to solve these problems, and as will be described below with reference to the drawings, as shown in the partial sectional view of the side surface of FIG. 8) The upper part of 8) is formed with a collar part (9) that can be integrally connected.
(C) A hakama-shaped vertical lip (2) is integrally provided which protrudes upward from the inner diameter upper end of the main body (8) and the inner diameter end of the collar portion (9) and goes downward in a curved shape. A vertical lip is provided between the cap nut (5) having the screw (4) screwed on the flange (9) on the inner diameter, and (e) the lower surface of the cap nut (5) and the upper surface of the vertical lip (2). A backup ring plate to be pressed is interposed and a cap nut is screwed to the main body. Further, as shown in FIG. 3, the inverted L-shaped step groove is provided on the inner diameter upper end of the body (8) and the inner diameter surface of the collar (9) without integrating the hakama-shaped vertical lip (2). , A U-shaped ring packing having a height protruding from the top surface of the main body when mounted in the inverted L-shaped step groove, and a pack-up ring plate for pressing the U-shaped packing on the bottom surface of the cap nut and the U-shaped packing. And the cap nut is screwed to the main body. Since the cap nut and the main body of the screw part on the outer periphery of the collar (8) are not always detached, the screw may be directly formed on the outer periphery of the collar (8), but a screw member made of metal or hard resin may be used. The threaded portion may be formed by attaching a fitting adhesive to the collar portion of the main body, or by screwing from the upper surface of the collar portion.

[Effects of the Invention] By doing so, (a) the vertical lip or U-shaped packing can absorb the difference in diameter of the drain pipe of the equipment inserted into the inner diameter of the vertical lip or U-shaped packing, and the drain of the difference in diameter can be obtained with a single adapter Can handle pipes. (A) Moreover, the sealing function is more reliable in the cap nut method of pressing the packing portion than in the case of contacting the inner diameter surface by simply inserting the drainage pipe. (C) Reducing the number of varieties due to the diameter difference can increase the production amount of one varieties and improve the productivity. (D) The number of molds for production is reduced accordingly, and the amount of mold capital investment can be reduced. (E) The smaller the variety, the easier the management
In addition, it leads to reduction of inventory burden. In addition, the external shape of the adapter of the present invention shown in the figure corresponds to various pipes having different inner diameters in order to prevent corrosion and electric contact of piping pipes in recent years. The external shape of the adapter allows one size and one type. When the external shape is adopted, the effect can be exerted more significantly in combination with the present invention that corresponds to pipe insertion of the drainage pipe to be inserted.
