Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a temporary stopper for installing a hydrant, and more specifically, it relates to a temporary stopper for installing a hydrant that does not get in the way of the pipe end core and has excellent watertightness. .

[Conventional technology] Temporary faucets for installing water faucets are made by burying water pipes within a concrete wall, completing interior wall interior work such as pouring interior concrete, laying tiles, and pasting decorative panels, and completing water pressure tests, etc. This is a temporary faucet that temporarily closes the faucet elbow at the tip of the piping until the faucet is installed after the water piping is completed.

Conventionally, such temporary faucets for installing water faucets were disclosed in Japanese Utility Model Publication No. 49-8046, Japanese Utility Model Publication No. 50-28055, and Japanese Utility Model Publication No. 52-91652.
Those described in Utility Model Publication No. 46-3081, Utility Model Application Publication No. 51868-1982, and Utility Model Application Publication No. 60-29509 are known.

[Problems to be solved by the invention] In recent years, pipe end cores as shown in FIG. 1 have come to be widely used in joints of pipes for attaching water faucets. This is because it is recognized to be effective in preventing rust in threaded joints.

In the same figure, 50 is a joint (90° elbow) buried in the wall 51, and female threads are cut at both ends.One female thread 52 is open from the wall surface, and the inner A resin tube end core 53 having a lip (not shown) is screwed into the inner part. For example, a water pipe 55 is screwed into the other female thread 54, and a tube end core 53 similar to that described above is also screwed into the female thread 54 (not shown in the drawing).

In the joint having the above configuration, the temporary stopper for attaching a water tap can be used to be screwed into the female thread 52 of the joint 50.

However, the above-mentioned Utility Model Publication Nos. 49-8046 and 50-
In the device described in No. 28055 and Utility Model Application Publication No. 52-91652, when trying to screw it into the female screw 52, the tip of the male screw of the temporary faucet for attaching the faucet hits the tube end core 53, and the screw The threaded portion of the tube cannot be covered with the tube end core 53, and rust cannot be prevented from occurring, resulting in poor watertightness.

On the other hand, the above-mentioned Utility Model Publication No. 46-3081,
-51868 and Utility Model Publication No. 60-29509,
Although it does not have the above drawbacks,
The technique described in Japanese Utility Model Publication No. 60-29509 has the disadvantage that a hexagonal wrench cannot be used, and the technique described in Japanese Utility Model Publication No. 56-51868 has the disadvantage that it is difficult to attach plasterboard (see Japanese Utility Model Publication No. 60-29509).

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a temporary faucet for installing a faucet in which the tube end core does not get in the way, a hexagonal wrench can be used, and plasterboard can be easily attached.

[Means for Solving the Problems] A temporary faucet for attaching a water faucet according to the present invention which achieves the above object has a partition part in the center of the cylindrical body, and the bottoms of the hollow parts on the left and right sides of the partition part. A hexagonal wrench engaging hole is formed in each of the cylindrical bodies, and a male screw is formed on the outer periphery of one end of the cylindrical body.

[Function] In the present invention, as shown in FIG.
Due to the presence of the hollow part 3, when screwing the temporary plug body 1 into the female thread 52, the tip of the temporary plug body 1 can be screwed into the tube end core 53 without hitting it, and also when attaching and removing the temporary plug body 1. A hex wrench (spanner) can be used.
Furthermore, since the partition wall is formed in the center of the cylindrical body, the partition wall will not be damaged even by small pressure or even when it is hit by instruments used in various construction works.

In addition, since the main body is cylindrical, there is no problem when pasting plasterboard.

[Example] Hereinafter, an example of the present invention will be described based on the accompanying drawings.

FIG. 1 is a cross-sectional view showing an attached state of a temporary faucet for attaching a water tap according to the present invention, and FIG. 2 is a cross-sectional view showing another embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a temporary faucet body for attaching a water faucet, which has a cylindrical shape. The cylindrical main body 1 has a partition wall 2 in the center thereof, and hollow parts 3 on the left and right sides of the partition wall 2,
3 is formed. Hexagonal wrench engaging holes 4, 4 are formed at the bottoms (inner parts) of the hollow parts 3, 3, respectively. It is preferable that the main body 1 is substantially symmetrical with respect to the partition wall 2. Here, "substantially" means that the length and shape may be slightly different, and the presence of screws, which will be described later, is not taken into consideration.

5 is a male thread formed on one end side of the cylindrical main body 1, and it is preferable that the shape of the male thread 5 is formed into a tapered surface whose diameter becomes smaller toward the tip.

The other end side of the cylindrical main body 1 is in an open state without being formed with a male thread.

To install the above temporary stopper, screw the male screw 5 of the temporary stopper main body 1 into the female screw 52 provided in the wall 51, advance it until it abuts the lowest surface of the tube end core 53, and then Screw on the stopper body 1.

The method of making the temporary stopper of the present invention is not limited, but for example, prepare a round bar (preferably an iron bar) that is shorter than the final product, set it in a press,
The hollow portions 3, 3 and the hexagonal wrench engaging hole portions 4, 4 are formed by cold forging. By this forging, the main body 1 is expanded to a predetermined length, and then a predetermined thread is cut to obtain a temporary plug having the shape shown in the figure.

Although one embodiment of the present invention has been described below, the present invention is not limited thereto, and the shape of the hollow portions 3, 3 may be made into two stages, as shown in FIG. 2, or may be made into multiple stages of three or more. can.

It is also possible to form a female thread in the hollow portion 3 on the right side and reuse the temporary stopper itself.

Furthermore, as an application example of the present invention, it is also possible to make the outer diameters of the left and right sides of the temporary faucet body different, and cut male threads on the left and right sides, so that it can be used with water faucets of different diameters.

[Effects of the invention] According to the invention, when the male thread is screwed into the female thread, due to the presence of the hollow part, the tip of the temporary stopper body can be screwed into the pipe end core without hitting it, making it watertight. In addition, a hex wrench can be used to install and remove the temporary stopper body, and since there is a partition wall in the center of the cylindrical shape, it is suitable not only for small pressure applications but also for equipment used in various construction works. The partition wall will not be damaged even if it is damaged.

In addition, since the main body is cylindrical, there is no problem when pasting plasterboard. Note that if the temporary stopper main body is formed symmetrically, threading can be performed on either the left or right side, and the threading can be performed without any selection, so that manufacturing is easy. Furthermore, there is the advantage that if the male thread is crushed or fails to be cut, the outer periphery of the other end can be used.
