  In the case of Patent Document 1 described above, by turning the cap 101, the inner surface of the pipe 109 can be spread by the four cylindrical portions 104, the end cap 100 can be attached to the pipe 109, and the attachment of the end cap 100 is easy Can do it.

  The present invention is to improve the end cap of Patent Document 1 mentioned above, and to provide an end cap for pipe which can be fixed to the pipe more firmly.

  The present invention relates to an end cap for a pipe attached to a pipe having one or both ends opened, wherein a metallic disc-like cap, a bolt portion fixed to a central portion of the cap, and the bolt at one end The inner wall pressing member includes a nut portion to be screwed, an inner wall pressing member made of a spring material for pressing an inner diameter surface of the pipe, and a mounting screw to be screwed to the other end of the nut portion. A plurality of legs disposed and having a central portion bulged outward and bent, a tip end bent inward from the legs, and a rear end provided with a hole into which the attachment screw is inserted The nut portion is inserted into the leg portion of the inner wall pressing member, one end of the nut portion is brought into contact with the rear end portion, the mounting screw is screwed into the nut portion, and the nut portion is attached to the inner wall pressing member The bolt is screwed into the other end of the nut to assemble the end cap for the pipe, and in a state where the inner wall pressing member is inserted into the pipe, the nut is rotated by rotating the cap, the rear end of the inner wall pressing member Move in the direction of the cap to expand the leg outward, and abut the leg against the inner diameter surface of the pipe to fix the end cap for the pipe.

  Further, guide tongues may be provided between the legs so as to project outward.

  Further, a saucer having a central hole into which the bolt is inserted and an outer peripheral peripheral edge rising from the peripheral edge of the central hole is interposed between the tip of the leg of the inner wall pressing member and the cap. When fixing the pipe, the tip end portion and the outer peripheral peripheral portion may be in contact with each other.

  According to the present invention, the end cap for the pipe is inserted into the pipe, and the cap is rotated to move the nut portion and the rear end of the inner wall pressing member in the cap direction to give the leg a force to expand outward. Is firmly pressed against the inner diameter surface of the pipe to firmly fix the end cap for the pipe to the pipe.

  Embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding portions in the drawings are denoted by the same reference numerals, and the description thereof will not be repeated to avoid the repetition of the description.

  The pipe end cap 1 of the present invention is used in a hanger pipe apparatus as shown in FIGS. 6 and 7. A plurality of slits 91 are provided in a support 9 fixed to a wall or the like, and an engagement hook (not shown) provided at a rear end portion of the hanger bracket 7 is inserted and attached to the slits 91. Then, the pipe 8 is inserted into the opening of the hanger bracket 7 and used as a hanger pipe device.

  Furthermore, a retaining member 71 is attached to the hanger bracket 7, and a part of the retaining member 71 enters between the slit 91 and the engagement hook to prevent the hanger bracket 7 from dropping off from the column 9. ing.

  As shown in FIGS. 6 and 7, the pipe end cap 1 of the present invention is attached to the openings 81 at both ends of the pipe 8 inserted into the opening of the hanger bracket 7.

  The pipe end cap 1 includes a metal disk-shaped cap 10, a bolt portion 11 fixed to the central portion of the cap 10, a pan 12, a nut portion 13, an inner wall pressing member 14, a washer 15, and a mounting screw 16. It is done.

  The tray 12 has a central hole 12a into which the bolt 11 is inserted, a central peripheral edge 12b rising from the peripheral edge of the central hole 12a, and an outer peripheral edge 12c rising from the outer periphery. The outer diameter of the outer peripheral edge 12 c is formed slightly smaller than the inner diameter of the pipe 8.

  The bolt portion 11 of the cap 10 is inserted into the central hole 12 a of the receiving plate 12, and the receiving plate 12 is attached to the cap 10. The tray 12 is pressed toward the cap 10 by a tip 14 b of a leg 14 a of the inner wall pressing member 14 described later.

  As shown in FIGS. 1 to 3, in the inner wall pressing member 14, three legs 14 a are arranged at equal intervals in the circumferential direction. And between the leg parts 14a and 14a, the guide tongue piece 14c is provided. The inner wall pressing member 14 is formed of a spring material, and three legs 14a are bent forward from a rear end 14e provided with a hole 14d into which a mounting screw 16 is inserted at the center. The guide tongues 14c are formed to protrude in the circumferential direction from the rear end 14e. The guide tongues 14 c are formed so as not to abut on the inner diameter surface of the pipe 8.

  The leg portion 14a is first bent in the direction orthogonal from the rear end portion 14e, and then bent toward the tip end in the shape of "he" in which the vicinity of the central portion bulges outward. The end 14b is bent inward from the leg 14a, and the end 14b is formed to be parallel to the receiving surface 12d of the tray 12.

  In the pipe end cap 1, the nut portion 13 is inserted into the leg portion 14 a of the inner wall pressing member 14, one end of the nut portion 13 is in contact with the rear end portion 14 e, and the screw 16 is screwed through the washer 15. Screw into The nut portion 13 is attached to the inner wall pressing member 14 by the nut portion 13 and the screw 16. And the bolt part 11 which attached the saucer 12 to the other end of the nut part 13 is screwed in, and the end cap 1 for pipes is assembled.

  The outermost bulging portion of the leg portion 14 a of the inner wall pressing member 14 of the assembled pipe end cap 1, that is, the apex portion of the “H” shape is formed slightly larger than the inner diameter of the pipe 8.

  The pipe end cap 1 thus configured is inserted from the opening 81 of the pipe 8 as shown in FIG. At this time, the leg portion 14a is slightly bent in the inward direction and inserted. When the cap 10 of the pipe end cap 1 is turned in this state, the nut portion 13 and the rear end portion 14e of the inner wall pressing member 14 move in the direction of the cap 10 by the bolt portion 11 and the nut portion 13. By this movement, the leg portion 14a of the inner wall pressing member 14 is axially contracted, and a force is applied to expand the leg portion 14a outward. As a result, the leg portion 14a and the inner diameter surface 82 of the pipe 8 are firmly pressed. Then, as shown in FIG. 4, the tip end 14b of the leg 14a abuts on the central peripheral edge 12b of the pan 12, and the reaction force from this position causes the leg 14a to contact the inner diameter surface 82 of the pipe 8. The contact force is maintained, and the pipe end cap 1 is firmly attached to the opening 81 of the pipe 8.

  Also, when removing the pipe end cap 1, the cap 10 is turned in the direction to loosen the bolt portion 11. By the bolt portion 11 and the nut portion 13, the nut portion 13 and the rear end portion 14 e of the inner wall pressing member 14 are moved in a direction away from the cap 10. By this movement, the leg portion 14a of the inner wall pressing member 14 extends in the axial direction, the contact force of the inner wall pressing member 14 can be weakened, and the pipe end cap 1 can be removed from the pipe 8.

  It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is shown not by the above description of the embodiment but by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
