  A single core with a shape in which the top is bent and crushed is attached to the tip of the insertion rod and inserted to a predetermined position in the main drilling portion, and the insertion rod enlarged portion is press-fitted into the inner diameter portion of the cylindrical body, and further expanded. The top of the core is bent and deformed by pressing the upper flange of the diameter portion.

  However, the conventional single core is based on a method in which a mounting edge attached to the distal end of the insertion rod is locked by a fastening head screwed into the insertion rod, with a protruding edge protruding inwardly at the lower end of the core. In order to mount the core member, it was necessary to remove the fastening head once, insert the core member, and screw the fastening head again.

  In addition, there is no special locking structure for the insertion rod at the top of the core, and it depends exclusively on the threaded support of the protruding edge of the lower end and the fastening head. There was a problem.

  Furthermore, in the past, the surface of the metal main body was locally covered with an elastic film, but in addition to the problem that the diameter of the core member expanded due to the press-fitting of the diameter-increasing portion of the insertion rod, it was attached to the tip of the insertion rod. According to the protruding shape of the metal body tip end edge, the core member inner diameter space does not have room for the locking flange side of the insertion rod tip, such as the fastening head base, and the core member is difficult to engage. There was also a problem.

  In view of the above problems, the present invention intends to cope with this, and coats the entire outer surface of the core member with an elastic material, and the lower end edge of the coated elastic material protrudes inside the lower end edge of the metal body, It becomes a projecting body that engages with the insertion rod locking shape part, so that it can be inserted into the locking recess provided on the insertion rod with one touch by the plastic elasticity of the metal main body or the elastic film covering its outer surface I made it.

  With such a configuration, the coated elastic material directly contacts the insertion rod and stabilizes the engagement with the insertion rod by the flexible elasticity, and the pressure contact with the hole wall pressure contact surface after the core member has been subjected to the diameter expansion crimping. The water-tight effect by is further enhanced.

  Further, the engagement structure to the insertion rod is formed at the inner diameter end edge of the core member upper end bending structure portion so that the insertion rod is engaged on the upper end side of the member, and the engagement mechanism does not exist at the lower end portion. It was configured to be compatible with insertion bars.

Further, the shape of the engagement protrusion on the insertion rod is a protrusion that circulates around the inner diameter of the core member corresponding to the member engagement environment of the insertion rod, or a protrusion that is arranged at an appropriate interval on the circumferential line of the inner diameter of the core member. The body is configured to accommodate a wide variety of insertion rods.

  Hereinafter, an embodiment of the present invention in which a close core is mounted from the installation of a water faucet will be described with reference to the drawings. 3 is a core member made of a plastic material such as pure copper or phosphorous deoxidized copper, and the outer surface is bent to be bent by pressing on the top 33 of the cylindrical body 3 to which a coating layer 37 made of an elastic material such as rubber is fixed. The structure 35 is provided, and a flange portion 34 for supporting the core member is formed on the upper surface of the water main pipe 2 to be attached.

  The bent structure 35 has a widened shape in which the peripheral wall protrudes slightly to the outside due to bending, and is inserted into the main pipe punching portion 11 while being engaged with the insertion rod 4, and has a tapered surface at the lower end of the flange 43 of the insertion rod. By pressing the top portion 33 by press-fitting, the outer peripheral wall 36 is bent and widened and bent, and the widened peripheral wall 36 protrudes further and is pressed against the inner wall of the water faucet water inlet 11.

  The coating layer 37 is a projecting shape in which the entire outer surface including the lower end edge of the main body made of a plastic metal is covered with an elastic material, and the lower end edge of the covering elastic material coating layer protrudes inside the lower end edge of the metal main body. It is formed in the body 31a, and is configured such that the lower end of the protruding body 31a is suspended on the upper surface of the locking flange 44 of the insertion rod 4.

  The core member 3 is attached to the insertion rod 4 when the tip of the insertion rod 4 is inserted from the top 33 of the cylindrical main body 3 and the lower end of the core member mounting portion 41 and the upper end of the top 33 of the cylindrical main body 3 abut each other. The narrowed portion is pushed open by the elasticity of the main body itself, and the insertion rod is press-fitted. When reaching the upper end of the locking flange 44, the lower end of the projecting body 31a is fitted into the upper end surface of the locking flange 44, and the engagement member It will be stopped.

Further, since the bent structure portion 35 of the top portion 33 of the core member 3 is bent into a dogleg shape and its upper end inner diameter edge protrudes inwardly, the protruding portion 31 b is the core of the insertion rod 4. The core member 3 is stably engaged with the insertion rod 4 in combination with the support groove 48 formed on the upper end side of the member mounting portion 41, coupled with the lower end locking of the 31a.
In some cases, the protrusion 31b may not be provided.

  The protrusion 31a has a shape of a protrusion 31e that circulates around the inner diameter of the core member as shown in FIG. 3, or a protrusion 31f that is arranged at appropriate intervals on the peripheral line of the inner diameter of the core member as shown in FIG. Can respond as.

  Next, the mounting configuration of the water-adhesive core according to the present invention to the water faucet 11 with a saddle and the structure of the water faucet with a saddle will be described with reference to FIG. A saddle 12 fastened to a main pipe 2 of a water pipe in which a water faucet is installed, and a water inlet 11 is opened above the saddle 12.

  The upper part of the water flow port 11 is a valve chamber 13, which stores a ball valve 15 that is rotated by an operating rod fitted to the ball valve rotation shaft 14, and opens and closes the water flow path 16 to the branch pipe. The upper portion of the valve chamber 13 is an open hole 18 and is normally closed by a cap 17.

  First, when the water faucet is attached to the main pipe 2 of the water pipe where the water faucet 1 is installed by the saddle 12 attached to the water faucet, the cap 17 is removed and the ball valve 15 is opened, the water faucet Since the through hole from the open hole 18 to the main pipe 2 is opened through the valve hole 19, the perforated water through hole 21 is drilled in the main pipe 2 through the open hole by a punching machine.

  When the perforated water passage hole is perforated, water overflows into the drainage channel provided in the perforator due to the water pressure of the main pipe 2, and impurities such as chips from the perforation are discharged together with the overflow water, so the ball valve 15 is closed. Then, the insertion rod 4 to which the core member 3 is fixed is joined to the insertion portion 5 as shown in FIG. The part 51 is screwed and the ball valve 15 is opened.

  By opening the bulb valve 15, the through hole from the water faucet upper opening 18 to the main pipe 2 through the valve hole 19 is opened again. If the length of the insertion rod 4 cannot be accommodated in the space between the insertion rod accommodating portion 52 of the insertion device 5 and the opening hole 18 of the water faucet, the length of the insertion rod 4 is increased by interposing a space adapter 6 as shown in FIG. Adjust the height.
