Description

[Detailed explanation of the invention] [Industrial application field] This invention is a flexible pipe (hereinafter referred to as "flexible pipe")
This is a piping tool used when installing indoor piping for city gas, etc., using a flexible pipe that is used to connect the end of a flexible pipe to an interior wall before construction of an interior wall. This invention relates to a wire hooking tool for later pulling out the wire through a hole.

[Conventional technology]

Currently, when performing indoor city gas piping using flexible pipes, as shown in Figure 1, all piping must be completed before the interior wall is constructed, and after the interior wall is constructed, all piping must be completed. Insert the flexible pipe 04, which has been temporarily fixed to the stud 02 etc. through the bolt mounting hole 01 using the fixing wire 03 and the nail 06, into the bolt mounting hole 01 using the rod-shaped hooker 05 shown in FIG. A construction method is adopted in which the end of the flexible tube 04 is pulled out by hooking the stop wire 03 on its tip and pulling it out from the collar attachment hole 01, and a connecting fitting is attached to it to connect it to the collar.

[Issues with conventional technology]

As mentioned above, the interior wall will be constructed after the piping of the flexible pipe 04 is completed, and since the piping and the interior wall are constructed by different contractors, the flexible pipe 04, which has been temporarily fixed to the mounting hole 01, The position of the stopper 03 may be separated. As a result, as shown in FIG. 3, the hooker 05 cannot reach the stopper wire 03 through the collar attachment hole 01, which has a relatively small diameter.

From this point of view, the present invention provides a tool that can easily pull out a flexible pipe by hooking it on the stop wire through the stopper mounting hole, even if the positions of the stopper attachment hole, the flexible pipe, and the stop wire are far apart. The purpose is to

[Means to solve the problem]

The configuration of the present invention is as follows.

A shaft rod made of elastic wire wound into a coil is extended from the handle, and an L-shaped hook is attached to the tip of the shaft rod, and an L-shaped hook is attached to the shaft rod so as to be slidable thereon. A wire hooking tool consisting of a sheath tube attached.

[Effect]

To use the above tool, place the L-shaped sheath tube at the collar mounting hole, facing the wire (flexible tube), hold the sheath tube with one hand, and hold the handle of the tool with the other hand. Insert it behind the interior wall. As a result, the shaft rod bends 90 degrees at the sheath pipe and enters the back side of the interior wall, making it easy to bring the hook at the tip close to the stop wire. Then, insert the stop wire into the hook from the entrance of the loop, rotate the hook 180 degrees, and the stop wire will enter the loop of the hook. Please note that this work is done while looking inside through the collar mounting hole. So, when I pulled the handle,
The retaining wire can be removed from the peg and the flexible tube can be pulled to the collar mounting hole. Once the stop wire has reached the collar mounting hole, you can use a tool to pull it further out of the collar mounting hole, or you can pull it out by hand.

〔Example〕

A tool according to the present invention and an example of its use will be explained based on FIGS. 4 to 6.

As shown in FIG. 4, the tool consists of a handle 1, an axial rod 3 extending from the handle 1 and made of elastic wire wound in a coil, and an L-shaped rod attached to the tip of the axial rod 3. It consists of a hook 2 which is curved into a loop shape, and an L-shaped sheath tube 4 which is slidably sheathed around a shaft rod 3.

As shown in FIG. 6, the above tool is used by applying the sheath tube 4 to the locking attachment hole 6 provided in the interior wall 5 with the locking wire 7 facing the direction, and pressing the handle 1 while holding it with one hand. Hold the shaft rod 3 and insert it into the back side of the interior wall 5. . As a result, the shaft rod 3 is located at the sheath pipe 4.
As it approaches the stop wire 7 while bending 90 degrees, insert the stop wire 7 into the hook 2 from the entrance of the loop and rotate the hook 2 by 180 degrees.
goes into hook 2 and will not come off even if you pull it.

After hooking the stop wire 7 in the hook 2 in this manner, when the handle 1 is pulled, the stop wire 7 and the flexible tube 8 can be pulled out of the collar attachment hole 6 together.

It goes without saying that the stop wire 7 should be fastened to the nail so that it can easily come off.

[Effects of this invention]

As described above, the present invention uses a loop-shaped hook, so by simply pressing the hook against the stop wire, the stop wire is inserted into the hook from the entrance of the loop, and by rotating it 180 degrees, it will not come off even if pulled.

As a result, hooking on the stop wire becomes easy and reliable.

In addition, in this invention, an L-shaped sheath tube is slidably mounted on an elastic shaft rod, the sheath tube is placed on the collar mounting hole, the shaft rod is bent 90 degrees, and the rod is guided to the stop wire. Therefore, even if the stop wire is far away or close to an interior wall,
You can easily hang the hook.
