Description

[Technical Field]

[0001] The present invention relates to a faucet core insertion machine used to insert a faucet core with a saddle into a drilled hole after drilling a faucet with a saddle, which is set to prevent contact with the drilled hole in a water distribution pipe and to ensure the water flow diameter. [Background technology]

[0002] When inserting the water distribution valve core into the drilled hole, it must be firmly attached to the inner surface of the drilled hole, as simply inserting it will allow water to seep in through the gaps in the insertion part. Therefore, when inserting the core, pressure must be applied to the core against the inner wall of the drilled hole to expand its diameter and make it adhere tightly.

[0003] The prior art invention described in Patent Document 1 uses a screw-type handle that is rotated to lower the core to the drilled hole, and then rotates it further to expand the diameter of the core and attach it to the drilled hole.The invention described in Patent Document 2 reduces the number of rotations required for downward propulsion by pushing the handle down to the vicinity of the drilled hole, and moves the cam pin along the cam groove to expand the diameter of the core and attach it to the drilled hole.

[0004] Furthermore, the invention described in Patent Document 3 uses a spring that transmits the downward movement of the main body to the insertion rod, so that a marker indicating completion of insertion protrudes, instead of relying on the operator's sense to determine the completion of insertion, which previously had to be determined by pushing down the core. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-180648 [Patent Document 2] Japanese Patent Application Laid-Open No. 2017-127946 [Patent Document 3] Japanese Patent Application Publication No. 2019-107705 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the case of the invention described in Patent Document 2, in which a cam pin with a handle for rotating the equipment and an axial member with a head for holding and attaching the diverter valve core are fitted into a groove provided in the axial member, and the core is pressed in, if the length of the saddle-equipped diverter valve member is different, the installation position of the core will not match.

[0007] Therefore, the length (height) of the saddle-equipped diverter valve as a component attached to the perforated portion of the distribution pipe becomes an issue. For example, for currently used saddle-equipped diverter valves with a nominal diameter of 25, the length S from the top end of the diverter valve to the top of the pipe as shown in Figure 2 is 86 mm for the AF type without an intermediate structure, 100 mm for the AS type with an intermediate structure, and 102 mm for the BS type with a different intermediate structure. Therefore, depending on the component length and manufacturer of the saddle-equipped diverter valve, corresponding equipment is required.

[0008] Furthermore, when the core member is held and attached to the press-fit head and the rotating rod is lowered and inserted into the drilled hole in the water pipe, downward thrust using a screw-type rotation requires a large number of rotations, which results in unnecessary waste of time and effort. In addition, the water pressure of the flowing water entering from below during descent makes it difficult to propel the vehicle downwards in a vertical direction.

[0009] In the invention described in Patent Document 2, as shown in attached drawing 1 of the specification, the cam pin moves in the cam groove, so there is no change in the range of up and down movement. If the height position of the component length of the saddle-equipped branch valve differs from the initial setting value, the setting position of the core will shift up and down, which may result in insufficient protection of the drilled hole from contact. [Means for solving the problem]

[0010] The present invention aims to address the above-mentioned problems, a cylindrical faucet core insertion device for inserting a tapered portion formed on one end of a cylindrical faucet core placed in the internal space of a saddle-type faucet into a distribution pipe by protruding the tapered portion from the opening of the saddle-type faucet and inserting it into the distribution pipe, and expanding the diameter of the inserted tapered portion to make it fit tightly against the distribution pipe, thereby connecting the distribution pipe and the internal space of the saddle-type faucet with the faucet core; the device comprises: a cylindrical sleeve placed in the saddle-type faucet and having one end that leads to the internal space of the saddle-type faucet; a core mounting member placed in the internal space of the saddle-type faucet, to which the faucet core is attached, and which is pushed into the tapered portion of the faucet core to expand the diameter of the tapered portion; a rod inserted into the sleeve and connected at one end to the core mounting member; a height adjustment member placed at the other end of the rod; a cylindrical handle support member threadedly attached to the outer periphery of the other end of the sleeve; and a handle supported by the handle support member and used to move the rod. The height adjustment member and the handle support member are threadedly connected to each other, and by rotating the height adjustment member relative to the handle support member, the rod is moved axially within the sleeve, which in turn moves the core mounting member and the faucet core attached to it, positioning the faucet core in the interior space of the saddle-type faucet near the opening of the faucet. By rotating the handle (hereinafter referred to as the handle bar) and rotating the handle support member relative to the outer periphery of the other end of the sleeve, the handle support member (hereinafter referred to as the handle fixing member) is moved in the axial direction of the sleeve (hereinafter referred to as the outer sleeve) together with the height adjustment member, and the rod (hereinafter referred to as the rotation operating rod) is moved in the axial direction accordingly, thereby further moving the core mounting member toward the water distribution pipe, causing the tapered portion of the water distribution valve core to protrude from the opening and be inserted into the water distribution pipe, and by further pushing the core mounting member into the inserted tapered portion, the tapered portion can be expanded in diameter and brought into close contact with the water distribution pipe. The rotation rod is inserted into handle fixing members that screw-fit handlebars for rotation on both sides so that it can move up and down. A height adjustment member is rotatably set at the top of the rotation rod, and the height adjustment member has an adjustment male thread that screws into the handle fixing member set at the bottom. The handle fixing member also has an adjustment female thread that screws into the adjustment male thread of the height adjustment member at the top. The threading efficiency can be improved by using a trapezoidal thread for the adjustment screw.

[0011] This allows the position to be adjusted by rotating the rotating operating rod that holds and inserts the faucet core into the drilled hole in the water distribution pipe and the adjustment screw of the height adjustment member, so it can easily be adapted to cases where the height of the saddle-equipped faucet member length varies.

[0012] The rotation operating rod has a hollow cavity formed in its lower half, and a through hole drilled in this cavity that leads to the interior gap with the outer sleeve described below.Furthermore, a contact surface is formed on the outer surface, the top is attached to the lower part of the handle fixing member, and the lower end is connected to a water faucet mounting member that is attached to a saddle-type water faucet, and is rotatably installed inside the outer sleeve.

[0013] A core mounting member is connected to the lower end of the rotation operating rod, and abuts against the drilled hole in the water distribution pipe, ensuring a structure that allows the water distribution valve core to be smoothly inserted into the drilled hole in the water distribution pipe.

[0014] By configuring the rotation operating rod as described above, when it is propelled downward, running water enters the interior gap between the rotation operating rod and the outer sleeve through the through hole, making the hollow cavity of the rotation operating rod and the interior gap at the same pressure, allowing the rotation operating rod to be propelled smoothly. [Effects of the Invention]

[0015] As described above, the present invention provides a height adjustment mechanism for the handle fixing member and the height adjustment member, making it possible to accommodate saddle-type faucets of different heights. The process of lowering the core to the installation position and the process of expanding the core are separated. The equal pressure structure used for the lowering process makes it easy to lower the rotation rod, reducing the number of handle rotations. Furthermore, the core expands from the tapered portion touching the top of the drilled hole, minimizing the amount of rotation work. [Brief explanation of the drawings]

[Figure 5] FIG. 10 is a plan view of a pressing member that prevents the handle fixing member from slipping out of the outer sleeve. [Figure 6] FIG. 6 is a right side view of the pressing member shown in FIG. 5. DETAILED DESCRIPTION OF THE INVENTION

[0017] An embodiment of the present invention will now be described with reference to the drawings. Reference numeral 1 denotes a rotation operation rod, and a height adjustment member 3 is rotatably set at the top. The height adjustment member 3 has an adjustment male screw 31 threaded thereon to threadably engage with a handle fixing member 2 set at the bottom. An adjustment female screw 21 is threadedly set on the inner periphery of the upper part of the handle fixing member 2 to screw into the adjustment male screw 31 of the height adjustment member 3 to adjust its position.

[0018] The rotation operating rod 1 has a hollow cavity 12 formed in its lower half, and this cavity 12 has a through hole 13 drilled through it that leads to an interior gap 51 with the outer sleeve 5, which will be described later, and the outer surface of the outer sleeve 5 has an abutment surface 52 that indicates the lowered position where the water distribution valve core C is inserted into the water distribution pipe drilling hole P1 and the tip is expanded in diameter, and the outer sleeve 5 is fitted with a retaining flange 11 to prevent it from slipping out of the outer sleeve in the upward direction. An O-ring that moves within the interior gap 51 for a pressure equalization structure is attached to the retaining flange 11.

[0019] The outer sleeve 5 has its top connected to the lower part of the handle fixing member 2, and the water faucet mounting member 8 is connected to the lower end, and is fitted inside while holding an O-ring of the water stop member with the rotation operation rod 1.

[0020] The handle fixing member 2 is attached by threading handle bars 6 for rotation operation onto both sides of the rotation operating rod 1, which is inserted so as to be movable up and down, and is attached to the upper end of the outer sleeve 5. After adjusting the height by rotating the height adjustment member 3, the handle fixing member 2 is propelled downward by the handle bar 6 to expand the diameter of the water faucet core C and crimp it. The retaining member 4 is rotated by a tool hook groove 41 engraved on its top surface, and a male thread 42 engraved on the bottom is threaded into a female thread engraved on the inner periphery of the outer sleeve 5, preventing the handle fixing member 2 from slipping out.

[0021] As described above, the rotation operation rod 1 is installed inside the outer sleeve 5, leaving an interior gap 51. Therefore, when the rotation operation rod 1 is propelled downward, flowing water enters the interior gap 51 between the rotation operation rod 1 and the outer sleeve 5 through the core mounting member 7, the rotation operation rod 1, and the through hole 13, making the hollow cavity of the rotation operation rod and the interior gap the same pressure, allowing the rotation operation rod to be propelled downward smoothly.

[0022] To install the saddle-equipped diverter valve core insertion device of the present invention, a saddle-equipped diverter valve W is attached to the distribution pipe P at the distribution location, a diverter hole is drilled, the core insertion device is attached, and the height adjustment member 3 is pushed down to thread onto the adjustment female thread 21. The handle fixing member 2 is then rotated downward until its lower end abuts against the abutment surface 52 of the exterior sleeve, thereby inserting the diverter valve core C into the distribution pipe drilling hole P1 and crimping it against the drilling hole P1. The height adjustment member 3 and the rotation operating rod 1 are rotatable relative to each other, and it is preferable to prevent the rotation operating rod 1 from rotating while the handle fixing member descends its descent length R, thereby preventing the diverter valve core C from rotating and damaging it. When installing a diverter valve with a different nominal diameter, an adapter can be used between the diverter valve mounting member 8 and the saddle-equipped diverter valve W.

[0023] Once the water distribution valve core C has been inserted into the drilled hole as described above, the handle fixing member 2 is rotated up until it abuts the lower part of the retaining member 4, then the handle fixing member 2 and the height adjustment member 3 are unscrewed, and the height adjustment member 3 and the handle fixing member 2 are pulled up further to return them to their original positions before they were attached, and the water distribution valve core insertion device is removed. [Industrial Applicability]

[0024] The saddle-type faucet core insertion machine of the present invention is able to accommodate height adjustments for saddle-type faucets of different heights by providing height adjustment mechanisms in the handle fixing member and the height adjustment member.Furthermore, the process of lowering the faucet core to near the installation position and the process of expanding the core are separated, and the lowering process is performed using the same pressure structure.This makes it easy to lower the rotation operating rod, reducing the number of handle rotations, and since the faucet core is expanded from the state where it hits the top of the drilled hole, the rotation work can be minimized, making it highly useful in the water supply facility industry.
