Description

  The present invention relates to an outlet structure for a water faucet with a saddle used to draw fluid from various main pipes into a home or a building, and in particular, the outlet structure of the water faucet is directly provided with a flange. It can withstand external impacts such as land subsidence or earthquakes, and since the elastic member is equipped with a tube crimping member that crimps the tube, it is excellent in workability and crimpability and can be reused. The present invention relates to an outlet structure of a saddle-equipped water faucet having high pipe adaptability that can be applied to a pipe having a deviation.

The saddle-equipped water faucet is used, for example, when connecting a branch pipe to the main water supply pipe in order to supply tap water from the main water supply pipe to a home or a building. In this way, the water faucet with saddle is buried underground (not excluding ground installation), so it is frequently exposed to external impacts such as land subsidence and earthquakes, which breaks the water faucet with saddle. As a result, water leakage occurs.
In particular, frequent breakage of the saddle-equipped faucet occurs at the outlet part where the branch pipe is connected. This is because the outlet is attached perpendicularly to the main body of the faucet, and it is loaded vertically from external impact. It is for receiving. Therefore, the conventional technology has been developed in a direction to give flexibility to the branch pipe in order to solve such a problem, but does not present a fundamental solution that breaks the outlet structure. .

Next, the conventional technique will be considered.
Patent application 1 filed on January 8, 1992 under the name of “Improved water tap for water supply”, published on August 21, 1993, and “Water tap for water supply” on December 7, 1993 Patent Document 2 filed under the name and published on January 1, 1991, Patent Document filed on March 19, 1998 under the name “Anti-corrosion water faucet” and published on October 15, 1999 3. Patent Document 4 filed on September 18, 1998 under the name of “Saddle Tap” and published on April 25, 2004, “Leakage of Water Tap for Water Supply” on August 23, 1999 Patent Document 5, filed under the name “Prevention Structure” and registered on November 23, 1999, filed under the name “Saddle with Saddle” on September 16, 2000, and dated December 29, 2000 Registered Patent Document 6 discloses a water faucet with a saddle And which, in the present application is omitted specific explanation of the diversion stoppered saddle, briefly described within to aid the understanding of the present invention.

  FIG. 1A is a view showing a state in which a branch pipe is inserted into a conventional saddle-equipped water faucet. Referring to FIG. 1-a, the saddle-equipped water faucet is largely composed of a water faucet body 62 and a saddle 64. The water faucet body 62 is connected to a ball valve (not shown) inserted therein to control the ball valve, and a cap fastened to the upper end of the water faucet body 62 with a screw. And an upper cap 62a that blocks the fluid flow by blocking the opening that allows the insertion of the drilling equipment, and an outlet structure 62c that allows the fluid flowing from the main pipe 17 to flow into the branch pipe 1. Provided. Further, the saddle 64 serves to fix the water faucet with a saddle to the main pipe, and includes an upper saddle 64a coupled to the body of the water faucet and a lower saddle 64b fastened to the upper saddle 64a with a bolt. Composed.

  Next, in order to help understanding of the present invention, a conventional process of installing a watering tap with a saddle will be briefly described. A water faucet with a saddle is fixed to a predetermined position of the main pipe with the upper saddle and the lower saddle, and the opening and closing valve 62b is operated to open the flow path of the ball valve so that the fluid in the main pipe flows to the upper cap 62a. After that, in order to drill the connection hole in the main pipe, a drilling facility (not shown) is inserted into the flow path to provide the connection hole, and then the drilling facility is removed, and the opening / closing valve 62b is operated again to operate the flow. After the passage is cut off and then the branch pipe 1 is piped to the outlet structure 62c, the fluid in the main pipe 17 can flow into the branch pipe 1 by operating the on-off valve 62b. Complete plug installation.

  As described above, when a conventional water faucet with a saddle is subjected to an external impact such as ground subsidence after installation, the inflexible outlet structure 62c is first destroyed as shown in FIG. Because it is installed in the main pipe buried at a certain depth as described above, the work of connecting the branch pipe to the inflexible outlet structure is very difficult and the workability is greatly reduced. Yes.

  On the other hand, in order to solve such a problem, Patent Document 7 filed on April 21, 2001 under the name of “flexible pipe for connecting a faucet with a saddle” and registered on June 14, 2001. , Patent document 8 filed on October 20, 2001 under the name of “corrugated pipe for connecting faucet with saddle”, and registered on January 21, 2002, Patent Document 9 filed under the name of “S-band for faucet connection” and registered on March 5, 2002 is disclosed.

FIG. 2A is a diagram showing a flexible pipe 3 attached to a conventional saddle-equipped water faucet in order to solve the problems of the saddle-equipped water faucets of FIGS. 1A and 1B, and FIG. FIG. 2A is a diagram showing a state in which the flexible pipe 3 of FIG. 2A is attached to a water faucet with a saddle, and FIG. 2-C is a diagram showing a state in which the water faucet with a saddle in FIG.
Referring to FIGS. 2-a to 2-c, these saddle-equipped water faucets tried to solve the problems of the conventional saddle-equipped water faucets described above by adopting the flexible pipe 3. In such a technique, the outlet structure provided in the water faucet with a saddle is made of a non-flexible structure, and as shown in Fig. 2-c, the outlet structure is still damaged or has a problem of low workability. In addition, since a large number of flanges must be processed in the branch pipe and provided with an iron net and a rubber tube, there is another problem that the manufacturing cost increases.

FIG. 3A is a diagram showing another flexible pipe 70 attached to the conventional saddle-equipped water faucet in order to solve the problems of the saddle-equipped water faucet of FIGS. 1A and 1B. 3-b shows a state in which the flexible pipe 70 in FIG. 3-a is attached to the water faucet with saddle, and FIG. 3-c shows a state in which the water faucet with saddle in FIG. FIG.
The flexible pipe 70 shown in FIGS. 3A and 3B is another example of the flexible pipe shown in FIGS. 2A to 2C. However, only the problem of breakage of the outlet structure and low workability is shown. In addition, since the collar portion 70a must be separately formed on the branch pipe, there is still a problem that the manufacturing cost increases.

On the other hand, in order to crimp the branch pipe inserted into the outlet structure, the outlet structure is provided with a ball guide as a pipe crimping member, an example of which is shown in FIG.
Referring to FIG. 7, a ball guide 10 of a tube crimping member includes a metal ball 14 and an elastic material fixing portion 12 for positioning the ball by embedding the ball 14 along a peripheral surface at a predetermined interval. It consists of.
Referring to FIG. 8, the ball guide 10 is inserted into the pipe together with the O-ring 30, the pushing member 40, the packing member 50, the main body of the outlet structure 720 and the nut 200, and the ball 14 is tightened by tightening the nut 20. Crimps the outer periphery of the tube. The ball guide is disclosed in Korean Registered Design No. 30-301306.

However, as shown in FIG. 8, the conventional water tap with a saddle that uses the ball guide 10 of the tube crimping member loses or is inserted by the ball 14 coming out of the fixing portion 12 in the process of being inserted into the tube. After that, since it leaves the normal position, there is a problem in terms of workability and airtightness maintenance, and when the water faucet is replaced later, it cannot be reused due to the loss of the ball.
Such problems are particularly noticeable when inserted into a tube having a diameter larger than that of a tube having a diameter that allows the use of a ball guide. It means the ability to be used even for tubes with large diameters). Further, since the outer inclined surface of the ball guide and the inner inclined surface of the nut are in surface contact with each other, there is a problem that a large tightening force is required when the nut is tightened.

  In addition to such problems on and after construction, in order to produce the ball guide, a mold must be produced so that the ball 14 is positioned along the peripheral surface of the fixed portion 12. Therefore, the manufacturing cost is increased, and the balls 14 must be positioned one by one in the mold and then manufactured by injection molding. Therefore, there are problems that much time and effort are required in the manufacturing process. .

  Accordingly, there is a need for the development of a saddle-equipped water faucet that satisfies all of the workability, reusability of parts, pipe adaptability, low manufacturing cost, simple manufacturing process and high impact resistance. In response to such a request, the applicant has developed the present invention.
