Description

  The present invention relates to a flange type or screw type saddle water faucet, and more particularly, a saddle water faucet used during branching operation of a water pipe made of stainless steel pipe, steel pipe, copper pipe, or PE pipe, The saddle is a metal plate made of the same material as the water faucet, and its weight can be greatly reduced and corrosion between dissimilar metals can be prevented compared to the saddle made with conventional castings. Of course, energy saving, environmental protection, productivity improvement, logistics cost reduction, etc. can be realized, and when connecting the water faucet with a saddle, a lock nut is attached to the lower outer peripheral surface of the water faucet body. The main body of the hollow cylindrical fixing member that is screwed and formed with an outward projecting flange at the lower end is connected to the lower part of the water faucet body through the water hole of the saddle, and the upper surface of the flange is the edge of the water hole of the saddle On the underside After adjusting the outlet direction to which the branch pipe is connected by twisting the water faucet body in any horizontal direction, the lock nut is tightened and the flange of the fixing member is tightly attached to the lower surface of the saddle It is related with the coupling | bonding structure of the saddle water faucet which crimps | bonds to a saddle and couple | bonds a water faucet.

  The saddle water faucet is used at the time of branching of the water pipe, and is generally composed of two parts, a saddle coupled to the upper part of the outer peripheral surface of the water pipe and a water faucet coupled to the upper part of the saddle. Another band can be constructed on the other side of the saddle.

  Conventional saddle water faucets generally have a screw-type saddle water faucet, in which a screw portion is formed in the saddle and the main body of the water faucet, and the screw portion of the water faucet is screwed into the screw portion of the saddle. There is a flange-type saddle water faucet in which a flange is formed in the lower part of the main body of the faucet, a coupling portion is formed on the upper surface of the saddle, and the coupling is fastened with a number of bolts.

  As shown in FIG. 1 or FIG. 2, the general configuration of a conventional saddle water faucet is such that the saddle 20 is applied to the upper part of the water pipe to be branched, and the band 32 is applied to the lower part. The side of the band is tightened with bolts and nuts, a gasket 34 is inserted inside the center of the saddle, and a water faucet provided with an upper cap 12 and a water faucet bar 13 at the top of the saddle. Ten bodies are combined. Inside the main body, a ball 36 for ejecting tap water to the upper cap 12 or the branch pipe 35 by the rotation of the water faucet bar is built in. Then, the upper cap 12 is opened, a perforator (not shown) is attached, and the water pipe 30 is perforated at the center of the gasket 34. Such saddle water faucet configurations are known. Further, the conventional saddle 20 and band 32 are made of iron casting, and the surface is coated with anticorrosion, and the water faucet has components such as a main body, a ball, a water faucet bar, and an upper cap made of stainless steel or copper. Like alloys, it is made of materials with excellent mechanical properties such as corrosion resistance and strength.

  On the other hand, in general, the saddle water faucet includes a screw-type saddle water faucet (see FIG. 1) in which a screw portion 23 is formed on the saddle and the main body of the water faucet, and a flange 11 at the lower part of the main body of the water faucet. And a connecting portion 21 is formed on the upper surface of the saddle 20, and there is a flange-type saddle water faucet (see FIG. 2) for fastening the flange and the connecting portion with a bolt 31.

  However, the conventional saddle water faucet has a problem in that corrosion between different metals occurs at the bonding site because the casting saddle and the water faucet mainly made of stainless steel or copper alloy are different from each other. That is, the screw-type saddle water faucet of the type in which the saddle made of iron material and the main body of the water faucet made of stainless steel or copper alloy are directly screwed has a problem that corrosion between different metals occurs in the screw portion 23. . In addition, a flange coupling method in which a flange is formed at the lower part of the main body of the water faucet, a coupling portion is formed on the saddle and coupled with a bolt, a portion of the nut hole 24 formed for bolt coupling in the coupling portion of the saddle. However, there is a problem that corrosion between different metals occurs.

  On the other hand, when it is necessary to change the connecting direction of the branch pipes due to obstacles in the conventional saddle diverter, the flange type saddle diverter has a fixed outlet direction to which the branch pipes are connected. However, it is possible to adjust the outlet direction of the screw type saddle water faucet by changing the degree of tightening of the water faucet and the saddle. There is a problem that water leakage can occur.

  The present invention has been made to solve the above-mentioned problems, and provides a saddle made of a metal plate material produced by press working instead of a conventional saddle made of iron casting, and is lighter and more excellent in quality. Further, there is an object to provide a saddle water faucet, and in particular, it is an object to provide a flange type or screw type saddle water faucet which is free from the risk of corrosion between different metals.

  Further, the present invention is a saddle water faucet coupling structure capable of rotating and changing the outlet direction of the water faucet in an arbitrary horizontal direction, and the coupling portion of the saddle and the water faucet is arbitrary after the coupling. Therefore, it is an object of the present invention to provide a coupling structure for a saddle water faucet that does not rotate and does not cause water leakage at the coupling site.

  According to still another embodiment of the present invention, a saddle water faucet has a hollow cylindrical fixing member body in which a lock nut is screwed onto an outer peripheral surface of a lower part of the water faucet body and an outward projecting flange is formed at a lower end portion. Inserted into the lower part of the faucet body through the saddle's water hole and joined, and the upper surface of the flange is configured to be in close contact with the lower surface of the edge of the water hole of the saddle. After adjusting the outlet direction to be connected to the branch pipe by twisting, the lock nut is tightened, and the flange of the fixing member is tightly crimped to the lower surface of the saddle to join the saddle and the water faucet, thereby preventing the possibility of water leakage The saddle water faucet is configured to adjust the outlet direction of the water faucet in a horizontal arbitrary direction.

  In a saddle water faucet according to still another embodiment of the present invention, a main body of the fixing member and a lower portion of the water faucet body form a male screw portion on an outer peripheral surface of the main body of the fixing member, By forming a corresponding female screw part on the peripheral surface, it is screwed, especially if it is formed on the left screw and screwed, the opposite direction of the lock nut screwed with the outer peripheral surface of the water faucet body by the right screw method It is possible to prevent the saddle and the water faucet from being released arbitrarily by loosening, and it is a saddle water faucet that prevents the binding site from loosening and the occurrence of water leakage.

  As described above, the present invention can achieve the following effects by the above-described problem solving means and the configuration, connection, and operation relationship described later.

FIG. 7a is a perspective view showing another embodiment of the flange-type saddle water faucet of the present invention, and FIG. 7b is a view of the flange-type saddle portion of the present invention. FIG. 7c is a perspective view showing still another embodiment of the flange-type saddle dispensing tap of the present invention, and FIG. 8 is a perspective view of the screw-type saddle dispensing tap of the present invention. 9 is a perspective view showing an embodiment, FIG. 9 is a partial cross-sectional perspective view of the screw-type saddle dispensing tap of the present invention, and FIG. FIG. 10B is a perspective view showing still another embodiment of the screw-type saddle water tap of the present invention, and FIG. 10C is a screw-type saddle of the present invention. It is a perspective view showing other examples of a water faucet.

  In general, the saddle water faucet is largely composed of two parts, a saddle 20 coupled to the upper part of the water pipe 30 and a water faucet 10 coupled to the upper part of the saddle 20, and the saddle 20 is coupled to the water pipe 30. In order to do so, a band 32 can be further provided on the opposite side of the saddle 20.

  Depending on the method of connecting the water faucet 10 to the upper part of the saddle 20, it can be divided into a screw type saddle water faucet and a flange type saddle water faucet. As shown in FIG. 1, the former is a type in which a screw part 23 is formed in the lower part of the main body of the water faucet 10 and the upper part of the saddle, and the saddle 20 and the water faucet 10 are directly screwed together. In the screw-type saddle water faucet, when the iron material saddle 20 and the water faucet 10 made of stainless steel or copper alloy material are screwed together, there is a problem that it is difficult to prevent corrosion of the screw portion 23 between different metals. As shown in FIG. 2, the flange 11 is formed at the lower part of the main body of the water faucet 10 and is coupled with the coupling portion 21 of the saddle 20 and the bolt 31. Since the materials are different from each other, there is a problem that corrosion between different metals occurs in the portion of the nut hole 24.

  Corrosion between different metals that occurs between a saddle made of conventional iron casting and a water faucet made of stainless steel, or between a saddle made of iron casting and a water faucet made of copper alloy is naturally the same material. This can be solved by making a saddle and a faucet. By the way, the water faucet cannot be made of iron casting, so the saddle must be made of stainless steel or copper alloy, but in the conventional casting method, due to excessive cost increase due to the use of expensive materials, Reality is low.

  Hereinafter, a flange type saddle water faucet according to an embodiment of the present invention will be described in detail with reference to FIGS.

  According to one embodiment of the present invention, the flange-type saddle water faucet of the present invention is manufactured by pressing a metal plate material made of the same material as the water faucet, instead of a conventional saddle made of a cast iron material. This is one of the gist.

  The saddle 20 is bent by a press so as to surround the outer peripheral surface of the water pipe 30, and the vertical cross section has an arc shape. The coupling portion 21 formed at the center is formed by deep drawing of the press, Since this is a general technical content that can be implemented by those skilled in the art, a detailed description thereof will be omitted.

  The press working is a plastic working using a press, and is also called stamping. The press is equipped with a ram that reciprocates up and down, and is attached to the upper mold of the mold at the lower end. The lower mold is fixed to the upper surface of the lower bed, and a material material such as metal is placed on it. The product is compressed to produce a product having a desired shape and size. Press work is a collective term for many processes such as deep drawing, stretch-expand, forging, extrusion, and coining, which are methods of making a container by punching into a hole of a shear, bending, or die.

  In the present invention, producing a saddle by pressing a metal plate material can significantly reduce its weight compared to producing a saddle with a conventional casting, as well as energy saving, environmental protection, and productivity. It has many advantages such as improvement and logistics cost reduction.

  Several specific examples for stably connecting the saddle of the present invention manufactured by pressing a metal plate to the lower flange of the water faucet body with bolts will be given.

  The coupling portion 21 of the saddle 20 is formed with a large number of bolt holes having threaded portions on the inner peripheral surface, and the flange 11 of the water faucet 10 also corresponds to the bolt holes formed in the coupling portion 21. A plurality of bolt holes are formed, and the bolt 31 penetrates the bolt hole from above and is screwed into the bolt hole of the saddle 20 to be fastened, so that the saddle 20 and the water faucet 10 can be coupled. .

  In addition, a large number of bolt holes are formed in the coupling portion 21 of the saddle 20 and the flange 11 of the water faucet 10, and the body of the bolt 31 penetrates from the bottom to the top, and is tightened with the nut 33 at the top. The main body is configured to be coupled, and the bolt head is fixed by welding a metal plate in which a bolt head insertion hole having the same shape as the bolt head is formed on the lower surface of the coupling portion 21 so that the bolt 31 does not slip. Can be configured.

  Further, a number of bolt holes are formed in the coupling portion 21 of the saddle 20 and the flange 11 of the water faucet 10, the body of the bolt 31 penetrates from the bottom to the top, and is tightened with the nut 33 at the top, The water faucet 10 is configured to be coupled, and a bolt head can be welded to the lower surface of the coupling portion 21 so that the bolt 31 does not idle.

  In order to prevent corrosion between different metals, the saddle 20, the bolt 31, the metal plate and the nut 33 are preferably made of the same material as the water faucet 10.

  When the coupling portion 21 of the saddle 20 and the flange 11 of the water faucet 10 are coupled with the bolt 31, the projecting portion 39 of the seat 38 accommodates the projecting portion of the bolt head or the bolt body. It is natural to form

  An O-ring for preventing leakage or a plate-like packing 37 is interposed between the coupling portion 21 of the saddle 20 and the flange 11 of the water faucet 10. Since this is a technique generally used for preventing water leakage between the contact surfaces of the two plates, a detailed description thereof will be omitted.

  In the flange-type saddle water faucet of the present invention, a sheet 38 having an outlet 22 is interposed between the saddle 20 and the water pipe 30 to prevent water leakage, and the water pipe 30 and the saddle. It is configured to prevent corrosion between dissimilar metals between 20. In general, the sheet 38 is merely configured to maintain airtightness and prevent water leakage, and is positioned only at the outlet of the saddle 20 and the water pipe 30. However, the sheet 38 according to the present invention covers not only the outlet portion of the saddle 20 but also all the portions that come into contact with the water pipe 30, and does not only achieve the effect of preventing water leakage by maintaining airtightness. It is comprised so that the corrosion between the different metals which generate | occur | produce between the water pipe 30 and the saddle 20 may be prevented.

  The outlet 22 is a hollow passage through which water flowing out from a hole drilled in the water pipe 30 passes, and not only the seat 38 but also the center of the connecting portion 21 of the saddle 20 and the center of the flange 11 of the water faucet 10. Of course, it is also formed in the part.

  In the sheet 38, a hollow type protruding portion 39 excluding the outlet 22 fills a space formed between the inner surface of the coupling portion 21 formed by deep drawing and the outer peripheral surface of the water pipe 30. It is preferable that they are integrally formed. This is because the protruding portion 39 has an effect of performing a watertight function by being in close contact with the surface forming the space, and further, the saddle 20 and the sheet 38 can be easily aligned without deviation.

  In the present invention, a specific example for stably coupling the saddle 20 to the outer peripheral surface of the water pipe 30 is as follows.

  Since both end portions of the saddle 20 parallel to the longitudinal direction of the water pipe 30 are bent upward and the ring rod 40 is inserted into the space, as a result, only a part of the outer peripheral surface of the water pipe 30 is left and surrounded. Composed. Here, by tightening the two ring rods 40, 40 on both sides with bolts, the ring rod 40 uniformly presses both ends of the saddle 20, whereby the saddle 20 is applied to the outer peripheral surface of the water pipe 30. It is configured to be bonded in close contact uniformly.

  Further, a band 32 is provided on the opposite side with the water pipe 30 interposed therebetween, and the saddle 20 and the band 32 can be tightened and coupled together. The band 32 is manufactured by pressing a metal plate material, and is manufactured so that the lower surface of the water pipe 30 can be surrounded. The saddle 20 has both end portions of the saddle 20 parallel to the longitudinal direction of the water pipe 30. The ring rod 40 is bent upward, the ring rod 40 is inserted into the band 32, and both ends of the band 32 are bent round. The ring rod 40 is inserted into the band 32. By tightening with, the saddle 20 and the band 32 can be tightly coupled to the outer peripheral surface of the water pipe 30.

  The present invention can have the following effects by the configuration of the ring rod 40 as described above. First, since it has a coupling hole that allows a fastening bolt to be screwed in the vertical direction of the ring rod 40, the bolt can be more easily coupled by fixing the bolt than when no ring rod is provided. In addition, the contact area between the bolt and the male screw can be widened to improve the coupling force. Further, since the ring rod 40 is interposed in the longitudinal direction of the pipe at the fastening portion of the saddle 20 and the band 32, the contact area in the longitudinal direction of the pipe with the saddle 20 and the band 32 can be increased. Therefore, the fastening force can be improved by increasing the contact area. Further, the saddle-side ring rod 40 and the band-side ring rod 40 are tightened with a large number of bolts, so that the two ring rods 40, 40 pressurize both ends of the saddle 20 uniformly. The saddle 20 can be uniformly and tightly coupled to the outer peripheral surface of the water pipe 30 to ensure a firm coupling fixing force.

  Another embodiment for achieving stable coupling of the saddle 20 and the water pipe 30 by the ring rod 40 is as follows.

  Referring to the embodiment shown in FIG. 7a, the saddle water faucet of the present invention does not include a band and the saddle 20 surrounds the entire water pipe. In this case, the ring rod 40 is included in the coupling portion at the end of the saddle 20 and can be firmly and stably coupled to the water pipe 30 by bolts. Referring to another embodiment shown in FIG. 7b, the saddle water faucet of the present invention can be composed of a saddle coupled to the upper part of the outer peripheral surface of the water pipe 30 and a band 32 coupled to the lower part of the outer peripheral surface. is there. Here, the ring rod 40 is provided at a portion where the end of the saddle 20 and the end of the band 32 are joined, and as described above, the ring rod 40 at the saddle end and the ring rod at the band end are connected with bolts. 40 is uniformly pressurized, and the saddle 20 is bonded so as to be in close contact with the outer peripheral surface of the water pipe 30. Referring to FIG. 7c, still another embodiment of the present invention, the saddle 20 has one of both end portions of the saddle 20 parallel to the longitudinal direction of the water pipe 30 bent in a round shape. A rod 40 is inserted, and the other is connected to one end of a band 32 bent so as to surround the lower portion of the water pipe 30 by a hinge 41, and the band 32 is opposite to the end connected to the saddle 20 and the hinge 41. Since the side end portion is bent round and the ring rod 40 is inserted therein, the saddle 20 and the band 32 are tightened by tightening the saddle side ring rod 40 and the band side ring rod 40 with a bolt. Can be configured to be closely bonded to the outer peripheral surface of the water pipe 30. The above-described stable coupling structure of the saddle 20 and the water pipe 30 by the ring rod 40 is only a preferred embodiment, and is not limited to this, and any one that can be easily implemented by those skilled in the art. Can also be included.

  Hereinafter, a screw-type saddle water faucet according to another embodiment of the present invention will be described in detail with reference to FIGS.

  The screw type saddle water faucet of the present invention is made of a metal plate material made of the same material as the water faucet, instead of the conventional saddle made of iron material, like the flange type saddle water faucet according to the embodiment of the present invention. One of the features is that it is equipped with a saddle manufactured by pressing.

  The saddle 20 has a vertical section bent into a circular arc by a press so as to surround the outer peripheral surface of the water pipe 30, and a coupling portion 21 that is screwed into the water faucet 10 at the center is upward in a hollow cylindrical shape. It is formed by pressing so as to protrude. This is a general technical content that can be implemented by those skilled in the art, as described in the flange-type saddle water faucet, and a detailed description thereof will be omitted. Further, the description of the press processing and the advantages and effects of manufacturing the saddle water faucet of the present invention by pressing from a metal plate material are the same as described above, and the description thereof will be omitted.

  In the screw-type saddle water faucet of the present invention, a sheet 38 having an outlet 22 is interposed between the saddle 20 and the water pipe 30 to prevent water leakage, and the water pipe 30 and the saddle 20 are prevented from leaking. It is configured to prevent corrosion between different metals. In general, the seat 38 is merely a structure for maintaining airtightness and preventing water leakage, and is located only at the outlet of the saddle 20 and the water pipe 30. However, the seat 38 according to the present invention covers not only the outlet 22 portion of the saddle 20 but also all the portions that come into contact with the water pipe 30, and does not only achieve the effect of preventing water leakage by maintaining airtightness. In addition, it is configured to prevent corrosion between different metals generated between the water pipe 30 and the saddle 20.

  The outlet 22 is hollow to allow water flowing out from a hole drilled in the water pipe 30 to pass therethrough.

  In the present invention, considering that the water pipe 30 is a circular pipe, the inner surface of the joint portion 21 of the water faucet 10 that is screwed with the joint portion 21 of the saddle 20 is less likely to be in close contact with the outer peripheral surface of the water pipe 30. , There is only a space in the coupling portion 21 of the saddle 20. A hollow protrusion 39 can be integrally formed with the sheet around the outlet 22 so as to fill this space. The protruding portion 39 has an effect of a watertight function, and further has an effect of allowing the saddle 20 and the sheet 38 to be easily aligned without being displaced.

  In the present invention, a specific embodiment for stably coupling the saddle 20 to the outer peripheral surface of the water pipe 30 has the same configuration as the flange-type saddle water faucet of the present invention.

  Both end portions of the saddle 20 parallel to the longitudinal direction of the water pipe 30 are bent upward, and a ring rod 40 is inserted into each of the saddles 20 so as to surround only a part of the outer peripheral surface of the water pipe 30, Are tightened with bolts 31 to pressurize both ends of the saddle 20 uniformly, so that the saddle 20 is evenly closely attached to the outer peripheral surface of the water pipe 30 and is firmly fixed. Power can be secured.

  Referring to the embodiment shown in FIG. 10a, the saddle water faucet of the present invention does not include a band, and the saddle 20 can be formed to surround the entire water pipe. In this case, by providing the ring rod 40 at a portion to be joined at the end of the saddle 20, the bolt 31 can be firmly and stably joined to the water pipe. Referring to the embodiment shown in FIG. 10b, the saddle water faucet of the present invention can be composed of a saddle 20 coupled to the upper outer peripheral surface of the water pipe and a band 32 coupled to the lower outer peripheral surface. The band 32 is manufactured by pressing a metal plate, and is manufactured so as to surround the lower surface of the water pipe. The saddle 20 has both end portions of the saddle 20 parallel to the longitudinal direction of the water pipe rounded upward. The ring 20 is bent, the ring rod 40 is inserted into the band 20, and both ends of the band 20 are bent round. The ring rod 40 is inserted into the band 20, and the saddle side ring rod 40 and the band side ring rod 40 are tightened with bolts 31. Thus, the saddle and the band can be configured to be closely bonded to the outer peripheral surface of the water pipe. At this time, as described above, the ring rod 40 uniformly pressurizes both the ring rod 40 at the saddle end and the ring rod 40 at the band end with the bolt 31, and the saddle 20 is applied to the outer peripheral surface of the water pipe. Make sure to bond evenly. In another embodiment of the present invention shown in FIG. 10c, in the saddle 20, either one of both end portions of the saddle 20 parallel to the longitudinal direction of the water pipe is bent upward and the ring rod 40 is inserted into the other. Is connected to one end of a band 32 bent so as to surround the lower part of the water pipe by a hinge 41, and the band 32 is bent round at the end opposite to the end connected to the saddle 20 and the hinge 41, An annular rod 40 is inserted into the saddle 20 and the band-side annular rod 40 is tightened with a bolt 31 so that the saddle 20 and the band 32 are in close contact with the outer peripheral surface of the water pipe. it can.

  Still another embodiment of the ring rod 40 of the present invention includes a protrusion 40b for separating the bolt 31 from the water pipe 30 as shown in FIGS. 11 to 13, and the ring rod 40 has a hollow 40a. Is done. As shown in FIGS. 7a to 7c and FIGS. 10a to 10c, the protrusion 40b and the hollow 40a have a structure in which the ring rod 40 is formed by a rod filled with the contents of the ring rod. The configuration is different from the configuration in which the bolt is inserted. When the ring rod for coupling the saddle 20 and the band 32 is made of a solid rod, and a coupling hole for inserting a bolt is located in the middle of the ring rod, the thickness of the ring rod is ultimately determined by the thickness of the ring rod. There is a thinned portion at the hole portion, and the strength is lowered. As a result, when a large pressure is applied, a phenomenon that the portion of the coupling hole is bent occurs. Furthermore, since the ring rod is a rod-shaped member filled with contents, the bending strength is lower than that of a hollow rod. Moreover, since the coupling hole is formed in the said ring rod itself, if a volt | bolt is inserted and coupled, it may contact with a water pipe. Thereby, the corrosion between different metals will generate | occur | produce with the water pipe and bolt of a different material. Therefore, the present invention includes the hollow 40a so that a space is formed in the central portion in the longitudinal direction of the ring rod 40, thereby achieving the effect of improving the bending strength as well as the cost reduction effect due to the material saving. The bolt 31 is inserted and coupled to the protrusion 40b of the ring rod 40, and is spaced apart from the water pipe 30 to prevent contact with the water pipe 30, thereby preventing corrosion between dissimilar metals. Try to achieve an effect that can.

  The surface of the band 32 can be painted to provide anticorrosion and insulation functions.

  It is preferable to interpose a sheet 38 a for preventing corrosion between different metals between the band 32 and the outer peripheral surface of the water pipe 30. By the way, since it can be said that the main object of the present invention is to prevent corrosion due to contact between different metals, a saddle water faucet is configured using a saddle and a band formed of a metal material different from the water pipe. Of course, even if the saddle is pressed, manufactured and assembled with the same material as the water pipe, there is still a risk of corrosion. For this reason, the sheet 38 a is positioned between the lower band 32 and the outer peripheral surface of the water pipe 30, thereby preventing contact between the band 32 and the water pipe 30, thereby preventing corrosion. It can be so.

  By manufacturing the band 32, the ring rod 40, and the bolt 31 for fastening the two ring rods with the same material as the saddle 20, corrosion between different metals can be prevented.

  The sheets 38 and 38a of the present invention are made of rubber or synthetic resin like a conventional general packing.

  Hereinafter, a connecting structure of a saddle water faucet according to still another embodiment of the present invention will be described in detail.

Join. At this time, the upper surface of the flange 320 is configured to be in close contact with the lower surface 210 of the saddle 20. After the water faucet body 10a is twisted in an arbitrary horizontal direction and the outlet direction to which the branch pipe 35 is connected is adjusted, the lock nut 100 is tightened to fix the flange of the fixing member coupled to the water faucet body 10a. A feature is that the saddle 20 and the water faucet 10 are coupled by tightly pressing 320 to the lower surface 210 of the saddle.

  The saddle water spigot coupling structure of the present invention configured as described above can easily change the outlet direction of the water faucet by simply unscrewing only the lock nut 100 and tightening it, in the direction of the branch pipe 35. There is an advantage that can be combined together.

  Water leakage prevention packings (not shown) may be interposed between the lock nut 100 and the contact surface of the saddle 20 and between the fixing member flange 320 and the contact surface of the saddle, respectively.

  The fixing member 300 inserted into the lower part of the water faucet body 10a can be welded and joined to the lower part of the water faucet body 10a. In a preferred embodiment, the outer periphery of the main body 310 of the fixing member 300 A male screw portion 80 is formed on the surface, and a female screw portion 60 is formed on the inner peripheral surface of the lower part of the water faucet body 10a and screwed together. Here, the screw portion is formed as a left-hand screw (or right-hand screw), while the screw portion 50 formed on the outer peripheral surface of the water faucet body 10a and the female screw portion 70 of the lock nut 100 are right-hand screws (or Left screw). This is because the fixing member 300 and the lock nut 100 are respectively screwed into the inner peripheral surface and the outer peripheral surface of the water faucet body 10a via a left screw (or right screw) and a right screw (or left screw) in opposite directions. This is a coupling structure that prevents the water faucet 10 from loosening arbitrarily. That is, when a drilling machine is connected to a portion of the water faucet 10 where the upper cap 12 is mounted, and a drill is inserted into the water faucet 10 to pierce a water passage hole, the water faucet 10 There is an advantage that it can be prevented from rotating together with the perforating machine, and an easier operation can be achieved, and it is possible to prevent the saddle 20 and the water faucet 10 from loosening arbitrarily and causing water leakage. There is an advantage that can be.

  The saddle 20 can be manufactured by casting, or can be manufactured by pressing a metal plate material made of the same material as the water faucet 10.

  The saddle 20 is manufactured by pressing a metal plate made of the same material as the water faucet 10 in order to follow the trend that the use of water faucets made of stainless steel material, which is an expensive high-grade material, is gradually spreading. If the saddle and the water faucet are made of the same material, the phenomenon of corrosion between different metals can be prevented, and if the price of the material is expensive, the plate material is produced by pressing the material by casting. This is because it is much more advantageous in terms of manufacturing costs.
