[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water faucet used when connecting a branch pipe to a fluid pipe such as a water pipe.

[0002]

[Prior art]

 Conventionally, when drawing water to a newly built house, a water faucet with a saddle as shown in FIGS. 5 and 6 is used. This faucet with a saddle is fastened and fixed to a water pipe d by upper and lower bands b 1 and c 2 of a saddle part a, and a plug f having a ball valve e is attached to the saddle part a, and The cap g is removed, the perforator h is inserted, the hole i is opened in the water pipe d, the perforator h is pulled out, and at the same time, the ball valve e is closed to prevent spouting of water and the connection port on the side of the plug f. After connecting the branch pipe k to j, the ball valve e is opened to allow water to flow from the water pipe d to the branch pipe k.

[0003]

[Problems to be solved by the device]

 If such a water faucet with a saddle is used, even if a hole i is opened in the water pipe d, the ball valve e can be closed to prevent the tap water from being ejected. Therefore, it is necessary to stop the water flow through the water pipe d during construction. There is no annoyance to the residents in the surrounding area due to water interruption. However, a water faucet with a saddle has a lot of components such as a bronze plug body, a ball valve installed inside, and a hole for inserting a drilling machine, and a cap attached to the hole, resulting in high cost. There are drawbacks. The present invention has been made in order to solve such a conventional drawback, and an object of the present invention is to provide a water faucet which has a simple structure and can be manufactured at low cost.

[0004]

[Means for Solving the Problems]

 As a means for technically solving the above-mentioned problems, the present invention has a body for tightening and fixing to a fluid pipe such as a water pipe and a band portion, and the body has a hole for making a hole in the fluid pipe. A through hole through which the machine passes is formed, and a connection port for a branch pipe is provided in the upper part of the through hole. An operation shaft is rotatably attached to the main body, and a rotation arm is provided on the operation shaft and the tip thereof is provided. An engaging rod is attached to the section in parallel with the operating shaft, and a valve body is formed in the main body by forming a long hole in the side portion and inserting the engaging rod into the long hole. The gist is that the through hole can be opened and closed by sliding by rotating.

[0005]

[Work]

 Tighten the main body and the band part to fix it to the water pipe, insert a punch into the through hole to make a hole in the water pipe, pull out the punch, and at the same time rotate the operating shaft, the rotary arm and the engaging rod will If the valve body slides sideways to block the through hole to prevent water from spouting from the water pipe, connect the branch pipe to the upper part of the through hole, and then slide the valve body sideways again to open the through hole. Water can be passed from the pipe to the branch pipe.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 1 denotes a water faucet body having a through hole 1a for inserting a perforator, and a cylindrical connecting port 2 for connecting a branch pipe formed at an upper portion thereof. A screw 2a is provided on the outer circumference.

A substantially elliptical storage portion 1b is provided below the through hole 1a of the main body 1, and a lower storage portion 1d is further provided below the through hole 1a with a step portion 1c as a boundary. A packing 3 is fitted along the inner wall of d, and a holding plate 4 is fixed between the packing 3 and the step portion 1c with a screw 5 or the like. The holding plate 4 has a hole 4a having substantially the same size as the through hole 1a, and the center of the hole 4a and the central axis of the through hole 1a are aligned with each other. Further, the packing 3 has a lower portion cut in an arc shape so that it can be closely attached to the fluid pipe 6 when the body 1 is fastened and fixed to the fluid pipe 6 such as a water pipe.

Reference numeral 7 denotes a disc-shaped valve body for opening and closing the through hole 1a, which is received by the holding plate 4 and slidable in the storage portion 1b as shown in FIG. That is, a long hole 7a is pierced through the side surface of the valve body 7 in a diametrical direction, and the engagement rod 8 inserted in the through long hole 7a can be slid in the left and right directions in the storage portion 1a by an arc motion. Is done.

Reference numeral 9 denotes an operating shaft for operating the engaging rod 8, which is rotatably attached to the main body 1 as shown in FIG. It is fitted and has a watertight structure with respect to the main body 1, a rotary arm 11 is attached to the tip portion, and the engaging rod 8 is attached to the tip portion of the rotating arm 11 so as to be parallel to the operation shaft 9. There is.

Therefore, when the head 9b of the operating shaft 9 is rotated by an appropriate tool to rotate the rotary arm 11 in the counterclockwise direction as shown in FIG. It is possible to slide the valve body 7 from the left end to the right end of the accommodating portion 1b by reciprocating up and down along the vertical direction, and when the rotating arm 11 is rotated clockwise, the engagement rod 8 moves the valve body 7 The valve body 7 can be slid from the right end to the left end of the accommodating portion 1b by making one reciprocal movement in the vertical direction along the long hole 7a. At this time, the valve body 7 is preset so as to occupy almost half of the volume of the storage portion 1b.

Reference numeral 12 denotes a band portion, which has an arcuate contact portion 12 a that is in close contact with the fluid pipe 6 and mounting portions 12 b formed on both sides thereof, and mounting portions formed on both sides of the main body 1. The main body 1 and the band portion 12 can be fastened and fixed to the fluid pipe 6 by inserting the bolt 13 between them and the nut 14.

The water faucet according to the present invention is configured as described above, and when it is used in, for example, waterworks, it is possible to connect a branch pipe to a water pipe without interruption. To explain the procedure, first, the main body 1 and the band portion 12 are applied to predetermined positions of the fluid pipe 6, and the mounting portions 1e and 12b are fixed by tightening with bolts 13 and nuts 14. At this time, the packing 3 of the main body 1 comes into close contact with the fluid pipe 6 and the lower housing portion 1d becomes a closed chamber.

Next, the head portion 9b of the operating shaft 9 is rotated in a predetermined direction (counterclockwise direction in FIG. 2) with an appropriate tool, and the valve body 7 is moved from the left end to the right end of the storage portion 1b (shown in phantom in FIG. 1). Position) and the through hole 1a of the main body 1 and the hole 4a of the holding plate 4 are opened.

Thereafter, the perforator 15 is inserted from above the through hole 1a to open the hole 6a in the fluid pipe 6, and the perforator 15 is pulled out from the through hole 1a. At the same time, the valve body 7 is moved from the right end to the left end (see FIG. 1 to the position indicated by the solid line) to close the through hole 1a and the hole 4a of the holding plate 4. Therefore, even if water flows out from the hole 6a of the fluid pipe 6, it will not be ejected to the outside from the through hole 1a. Further, the water accumulated in the lower storage portion 1d is also blocked by the packing 3 and does not leak to the outside.

While maintaining this state, the branch pipe 16 is screwed and connected to the connection port 2 of the main body 1 with the screw 2a, and a predetermined pipe (not shown) is connected to the branch pipe 16. The head 9b of the operating shaft 9 is turned again to slide the valve body 7 to the position shown by the phantom line in FIG. 1, and the through hole 1a and the hole 4a of the holding plate 4 are opened to branch from the fluid pipe 6. Water can be passed through the pipe 16. The tool (not shown) that turned the operation shaft 9 at the end is removed from the head 9b.

[Effect of device]

 As described above, according to the present invention, the structure of the water faucet is extremely simple, and the bronze plug body such as the conventional water faucet with a saddle and the ball valve mounted inside are unnecessary. Since the number of parts is small, it can be provided at low cost.
