Description

  The present invention relates to a cleaning port adapter for enabling a press-fitting lid for a press-fitting type cleaning port to be applied to a screw type cleaning port mounted on a drain pipe end.

  The cleaning port connected to the drain pipe end and embedded in the floor has a lid that is detachably attached to the upper surface in order to prevent odor from rising from the drain pipe. The lid is flush with the floor in a state of being attached to the upper surface of the cleaning port so as not to obstruct walking.

  As a method of detachably attaching the lid to the upper surface of the cleaning port, there is a screw type cleaning port. The screw-type cleaning port is configured to screw a screw lid having a male screw portion on the outer peripheral surface thereof into a female screw portion on the inner peripheral surface of the cleaning port. When the screw cover is attached to or detached from the screw type cleaning port, the screw cover needs to be rotated on the upper surface of the cleaning port.

  However, a protrusion for rotating operation cannot be formed on the upper surface of the screw lid that should be flush with the floor surface. For this reason, two concave portions are formed on the upper surface of the screw lid, and when the screw lid is attached or detached, a dedicated tool having two claw portions that fit into the two concave portions must be prepared.

  Therefore, conventionally, a press-fitting type cleaning port using a press-in lid provided with an elastic body whose outer peripheral surface is in close contact with the inner peripheral surface of the cleaning port on the bottom surface side of the thin disk has been commercialized (for example, Patent Documents). 1). The outer peripheral surface of the elastic body is formed in a tapered shape, and the upper end portion of the outer peripheral surface of the elastic body is elastically deformed by pressing the press-fit lid in a state of being placed on the upper surface of the cleaning port. Press contact. A notch is formed in a part of the periphery of the thin disk of the press-fit lid, and the tip of the driver, which is a general-purpose tool, is inserted into the notch and the press-fit lid is removed from the cleaning port. There is no need to rotate the press-fit lid when attaching to or detaching from the cleaning port, and no special tool is required.

  Below, the adapter for cleaning openings concerning the embodiment of this invention is explained, referring to drawings.

  As shown in FIG. 1, the cleaning port adapter 1 is attached to a screw-type cleaning port 3 having a nominal diameter (first nominal diameter) excluding a minimum nominal diameter among a plurality of nominal diameters. The press-fit lid 4 having a nominal diameter (second nominal diameter) smaller than the diameter is made usable. The screw type cleaning port 3 is attached to the upper end of a drain pipe (not shown). The cleaning mouth adapter 1 can accommodate the eye plate 5 therein. In the press-fit lid 4, an elastic body 41 is attached to the bottom surface of the top plate 41, and a notch 43 is formed in a part of the outer periphery of the top plate 41. The press-fit lid 4 is attached to the cleaning port adapter 1 by a pressing force, and can be detached from the cleaning port adapter 1 using a general-purpose tool such as a screwdriver inserted into the notch 43.

  As shown in FIG. 2, the cleaning adapter 1 includes a flange 11, a male screw part 13, a step part 14, a connection surface 15, an eye plate step part 16, an operation on a main body 11 made of metal or resin. The bar 17 is integrally formed. The cleaning port adapter 1 is attached to the screw-type cleaning port 3 together with the packing 2.

  The main body 11 has a cylindrical shape having a flange portion 12 at an upper end portion. The inner diameter of the main body 11 is equal to the inner diameter of the second nominal diameter cleaning port. The male screw portion 13 is formed on the outer peripheral surface of the flange portion 12. The screw diameter and pitch of the male screw portion 13 are equal to the female screw portion 31 of the screw type cleaning port 3. The height of the flange portion 12 is shorter than the effective length of the female screw portion 31. The step portion 14 is configured by an annular plane located below the upper surface of the flange portion 12 by a length equal to the thickness of the top plate 41 of the press-fit lid 4.

  The outer diameter of the flange portion 12 is sized to match the first nominal diameter. Further, the inner diameter of the main body 11 and the inner diameter of the flange portion 12 are sized to correspond to a second nominal diameter that is one smaller than the first nominal diameter.

  The connection surface 15 is configured by an arc or a straight surface in a cross section in which the inner diameter gradually decreases from the inner peripheral edge of the step portion 14 toward the inner peripheral surface 111 of the main body 11. The step portion 14 and the connecting surface 15 constitute a fitting portion of the present invention together with the upper end portion of the inner peripheral surface 111. The eye plate step 16 is formed at the lower end of the inner peripheral surface 111 over the entire circumference. The eye plate step 16 is equal to the outer diameter of the eye plate 5 having the second nominal diameter.

  An operation bar 17 that is an operation unit of the present invention is disposed on the bottom surface of the main body 11 in the entire radial direction of the main body 11. The operation bar 17 does not necessarily need to be disposed in the entire radial direction, and an intermediate portion can be omitted. Moreover, the operation part of this invention should just be a shape which can make the operation force of a rotation direction act on the main body 11, and is not restricted to a rod shape.

  The packing 2 is made of an elastic material such as rubber as an example, and the outer diameter is equal to the inner diameter of the first nominal diameter cleaning port, and the inner diameter is equal to the outer diameter of the main body 11. The height of the packing 2 is made longer than the difference between the length from the upper surface 30 to the step portion 32 in the screw type cleaning port 3 and the length from the upper surface to the bottom surface of the flange portion 12 in the main body 11.

  In addition, when the length from the step part 32 in the screw type cleaning port 3 to the bottom face of the flange part 12 in the main body 11 is sufficiently small, the packing 2 can be omitted by filling the adhesive therebetween.

  When the press-fit lid 4 is applied to the existing screw-type cleaning port 3 shown in FIG. 3 (A), as shown in FIG. 3 (B), the screw cover 6 and the packing 7 are removed from the screw-type cleaning port 3, The cleaning port adapter 1 corresponding to the nominal diameter of the screw type cleaning port 3 is attached to the screw type cleaning port 3.

The cleaning port adapter 1 is rotated. The packing 2 is compressed in the vertical direction by the step portion 32 in the screw-type cleaning port 3 and the bottom surface of the flange portion 12 in the main body 11 and expands in the radial direction. As a result, the inner peripheral surface of the screw-type cleaning port 3 and the outer periphery of the main body 11 Keep airtight between the surfaces.

  By attaching the cleaning port adapter 1 to the screw type cleaning port 3 in the state shown in FIG. 3 (D), the nominal diameter is one smaller than the nominal diameter of the screw type cleaning port 3 as shown in FIG. 3 (E). The press-fit lid 4 having a diameter can be attached to the cleaning adapter 1. At this time, the eye plate 5 can be accommodated in the eye plate step 16 if necessary.

  The top plate 41 of the press-fit lid 4 is accommodated on the stepped portion 14 in the flange portion 12, and the upper surface coincides with the upper surface of the screw type cleaning port 3 and is flush with the floor surface 100. When the upper end portion of the elastic body 42 of the press-fit lid 4 moves downward from the step portion 14 toward the inside of the main body 11, it is gradually compressed by the connecting surface 15 to cause elastic deformation, and the inner peripheral surface of the main body 11. Press contact with 111.

  As described above, the press-fit lid 4 can be used without removing the screw-type cleaning port 3 from the floor surface. By preparing the cleaning port adapter 1 having a size corresponding to a plurality of nominal diameters excluding the minimum nominal diameter of the cleaning port, the press-fit lid 4 can be used for the screw type cleaning port 3 of plural kinds of nominal diameters. Can do.

  In this case, it is not necessary for the cleaning port adapter 1 of all sizes to have an inner diameter corresponding to the press-fit lid 4 having a nominal diameter that is one smaller than the nominal diameter of the cleaning port. For example, the inner diameter of the cleaning port adapter 1 used for the screw type cleaning port 3 having the largest nominal diameter can be made to correspond to the press-fit lid 4 having a smaller nominal diameter by two or more.
