  The present invention relates to a structure for mounting a pipe inserted into a pipe insertion hole of a pipe mounting member, and more particularly to a structure for attaching a pipe to a pipe mounting member having an inclined mounting surface portion without being orthogonal to a pipe center line.

Conventionally, as shown in FIG. 9, the pipe mounting structure inserted into the pipe mounting member has a pipe 103 from the mounting surface portion 102 on the washing side 1 side of the piping mounting member 101 made of the bathtub apron to the rear surface side on the bathtub side. There is what was attached through (patent document 1).
Japanese Patent No. 2715824

  Incidentally, as shown in FIG. 10, the pipe mounting member has a type 20 in which the mounting surface portion 21 is inclined at an angle of θ degrees with respect to the vertical surface portion 24, and the pipe is inserted into the inclined mounting surface portion 21 for mounting. In addition, there is a request for making the center line in the longitudinal direction of the pipe (hereinafter referred to as “pipe center line”) a right angle with respect to the vertical surface portion 24. The following structure 110 can be considered as an attachment structure that meets this requirement.

  That is, the pipe mounting member 20 is provided with a pipe insertion hole 23 extending from the mounting surface portion 21 to the inside of the annular rib 22 on the back surface side, and the opening peripheral edge 21a of the pipe insertion hole 23 formed in the mounting surface portion 21 is defined as the pipe center line. Inclined at an angle of (90−θ) degrees without being orthogonal to A, and the end face 22a of the annular rib 22 is orthogonal to the pipe centerline A. The piping 111 is provided with an annular flange 31 on the front surface and a male screw portion 32 on the rear surface, which are in contact with the contact surface portion 31 a via the packing 50, on the opening peripheral edge 21 a of the mounting surface portion 21. Is inclined at an angle of (90-θ) degrees with respect to the piping center line A. The pipe 111 is inserted from the surface side of the pipe mounting member 20 into the pipe insertion hole 23 and the inside of the annular rib 22, and the nut 51 is screwed to the male screw part 32 from the back side, and the end face of the mounting surface part 21 and the annular rib 22. 22 a is clamped and held by the flange 31 and the nut 51 and attached to the pipe mounting member 20.

In this mounting structure 110, in order to facilitate the insertion of the pipe 111, the inner diameters of the pipe insertion hole 23 and the annular rib 22 are made larger than the outer diameter of the pipe 111, and the pipe 111 is inserted into the pipe insertion hole 23 with a large clearance gap. Insert in the state.

  However, in the mounting structure 110, the opening peripheral edge 21 a of the mounting surface portion 21 is inclined at an angle of (90−θ) degrees with the pipe center line A, and therefore the opening peripheral edge 21 a of the mounting surface portion 21 from the tip surface 22 a of the annular rib 22. The distance dimension X along the pipe center line A is smaller than the distance dimension Y on the pipe center line A from the virtual plane in contact with the opening peripheral edge 21a of the mounting surface portion 21 to the virtual plane in contact with the end face 22a of the annular rib 22. (Referred to as “loose side” in FIG. 10) and a large side (referred to as “tightening side” in FIG. 10).

  Therefore, the attachment structure 110 receives an external force F in a direction in which the pipe 111 in the attached state is directed from the tightening side toward the loose side as shown in FIG. Alternatively, the pipe 111 is loosened due to vibration caused by a water hammer, and the holding force of the flange 31 and the nut 51 of the pipe 111 against the mounting surface portion 21 and the annular rib 22 is loosened. This may cause a problem that the water seal of the packing 50 cannot be secured. Note that the above problem also occurs in an attachment structure in which a pipe is inserted and attached to an inclined attachment surface portion such as a wash basin or a sink counter.

  In order to solve the above problems, an object of the present invention is to provide a pipe mounting structure that does not loosen the pipe and move it to the other side even if the pipe receives an external force or generates vibration. .

In order to provide a stable pipe mounting structure in which a pipe attached to a pipe mounting member having an inclined mounting surface portion that is not orthogonal to the pipe center line is loosened and is not moved to the user's side, A pipe mounting member provided with a pipe insertion hole leading from the mounting surface part on the side to the inside of the annular rib on the other side, and one side that is inserted into the pipe insertion hole and abuts the opening peripheral edge of the mounting surface part with or without packing A pipe provided with an annular flange and a male screw part on the other side, and a nut screwed into the male screw part of the pipe from the other side, and the pipe mounting member pipes the opening peripheral edge of the pipe insertion hole formed in the mounting surface part. Inclined without being orthogonal to the center line, and the end face of the annular rib is orthogonal to the pipe center line, and a looser side and a tightened side are formed between the opening edge of the pipe insertion hole and the end face of the annular rib. Flange and A pipe mounting structure in which the opening peripheral edge of the mounting surface and the end surface of the annular rib are clamped and held with a tightened nut, and the outer surface between the annular flange of the pipe and the male screw is loosened and tightened Positioning stoppers that are provided with positioning surface parts in parallel, are fitted on the annular ribs to prevent the movement toward the loose side with the annular ribs, and the peripheral edge of the opening through which the pipe is inserted is clamped and held by the annular ribs and nuts A pipe mounting structure inserted into a pipe mounting member, wherein two positioning surface portions of the pipe are sandwiched between two parallel positioning pieces provided on the positioning stopper.
Note that the looseness-side means that the interval dimension along the pipe center line from the end surface of the annular rib to the opening periphery of the mounting surface portion is from the virtual plane in contact with the opening periphery of the mounting surface portion to the virtual plane in contact with the end surface of the annular rib. The side smaller than the interval dimension on the center line is referred to, and the fastening side refers to the larger side.

  In order to prevent the positioning stopper and the pipe from co-rotating together with the nut when the nut is screwed onto each male screw portion of the two pipes, the means adopted by the invention according to claim 2 includes: The pipe mounting member is provided with two opening rims of the annular rib, the pipe insertion hole, and the mounting surface part, and includes two pipes and two nuts inserted through the annular rib and each pipe insertion hole. The positioning stopper is provided with two sets of the positioning pieces in two pairs and two opening peripheral edges through which the pipes are inserted, and is fitted on both annular ribs toward the looser side of the two pipes.

Annular flange and two nuts Perform a mounting structure of the piping inserted through the pipe mounting member sandwiched claim 1 wherein the positioning surface of the two pipes in two sets of positioning pieces.

  The pipe mounting structure inserted into the pipe mounting member according to the first aspect of the present invention is the two positioning pieces provided on the positioning stopper, and the pipe is loosened with the two positioning surface portions of the pipe sandwiched therebetween. Since the pipe is not moved, even if the pipe receives an external force or generates vibration, the pipe can be loosened and the pipe can be stably attached without moving to the user side.

  In the pipe mounting structure inserted into the pipe mounting member according to the second aspect of the present invention, the positioning stopper is externally fitted to the two annular ribs without rotating, so that the pipe is screwed to the male screw portion of each pipe. It is possible to prevent the positioning stopper from rotating together with the nut. In addition, since the positioning stopper in a non-rotating state holds the piping by sandwiching the two positioning surface portions of each piping with two sets of positioning pieces, the piping is connected together with a nut screwed to the male screw portion of the piping. You can prevent them from rotating together.
