Abstract

<P>PROBLEM TO BE SOLVED: To provide a low cost pipe penetrating tool which can penetrate a drain pipe by easily and surely removing clogging. <P>SOLUTION: The pipe penetrating tool comprises a pipe body 2 whose tip end 3 is inserted into an opening 17 of the drain pipe 16 from which the clogging 18 is to be removed, a liquid introducing pipe connected to the pipe body 2 for introducing a pressurized liquid into the drain pipe 16, a water stop faucet 7 with a check valve for backflow prevention, and an elastic body, such as synthetic rubber 9, installed on the outer periphery of the tip end 3 of the pipe body 2. In the elastic body, a doughnut-shaped rubber ring 9 is held by washers 5, 6 from both sides and tightened by a butterfly nut 10 through an outer pipe body 12. As a result, the rubber ring 9 is elastically deformed toward the outer periphery in the radial direction to expand the diameter, thereby coming into close contact with the inner peripheral surface of the drain pipe 16. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

The present invention relates to a through-pipe tool that removes clogging of a drain pipe and penetrates the drain pipe.

Generally, when a drain pipe is clogged at home or the like, a wire is inserted into the drain pipe to remove the clog. However, when a wire is used in this way, when the wire is pulled out, sewage may sag and stain the surroundings. In addition, the distance that a wire can reach is determined, and it is often short. In addition, the wire is weak to the bending of the drain pipe and may not advance from the bent portion. In order to respond to such a demand, a tube passing tool disclosed in the following patent document has been developed. This tube passing tool has a complicated structure and a problem in durability of the used bag body, and there is a problem that the manufacturing cost is high.
JP 2001-146682 A

  It can be used for drainage pipes with long and complicated bends and clogged shape components, and can be used easily by non-professional engineers and ordinary households. For the purpose of provision.

  In order to achieve the above-described object, the tube passing tool according to the present invention is provided on the outer periphery of the distal end portion of the tubular body, and is elastically deformed outward in the tubular body radial direction by tightening the wing nut to expand the diameter. An elastic rubber body that is in close contact with the inner peripheral surface of the drain pipe is provided.

  Further, a water conduit for introducing the pressurized liquid into the drain pipe is connected to the pipe body.

  Then, in the pipe connection method according to the present invention, the pipe body in each of the above-described pipe connection tools is inserted into the opening of the drain pipe to be clogged, and the outer pipe body is unwound by tightening the wing nut. The elastic body is expanded and brought into close contact with the inner peripheral surface of the drain pipe to seal the gap between the outer peripheral surface of the pipe body and the inner peripheral surface of the drain pipe, and then the pressurized liquid from the liquid guide pipe is introduced from the pipe body to the drain pipe. To do.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a tube-connecting tool according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a main part showing a state where the tube-connector is inserted into a drain pipe. In each drawing, the pipe 1 according to this embodiment includes a water stop cock with a check valve for preventing a backflow, and the tube 1 has a tip 3 inserted into the opening 17 of the drain pipe 16. Have. In the vicinity of the opening 8. The reversely supported valve and the reversely supported valve upper end portion are connected to the liquid introduction pipe 19 through the hose 13 and the faucet 15 fixed by the fixing bands 17 and 17, respectively.

  An elastic body 9 that is expanded in diameter by tightening a wing nut is fixed to the outer periphery of the distal end portion 3 of the tube body 2. The elastic body 9 is made of an elastic body such as synthetic rubber. In the vicinity of the distal end portion 3 on the outer periphery of the tube body 2, a retaining nut 4 is secured to prevent the rubber body 9 during diameter expansion from falling off the distal end portion 3.

  Next, a method for passing the drain pipe 16 using the pipe connecting tool 1 will be described with reference to FIG. In this case, the distal end portion 3 of the tube body 2 is inserted into the opening portion 17 of the drainage pipe 16 in the drainage pipe 16 from which the clogging 9 is to be removed. Therefore, the diameter of the wing nut 10 is expanded outward in the radial direction of the tightening tube 2 and is brought into close contact with the inner peripheral surface of the drain pipe 16. In this way, the gap 17 @ between the outer peripheral surface of the tube body 2 and the inner peripheral surface of the drain pipe 16 is sealed.

Subsequently, the flow path of the cock 7 is released to the outside, and when the faucet 15 is opened, the pressurized liquid W (for example, tap water having a pressure of about 0.2 kg / cm ² is used here) from the liquid introduction pipe 19 is used. ) Is introduced into the drainage pipe 16 through the pipe body 2, and the clogging 18 in the drainage pipe 16 is pushed away in the direction of the arrow 11 and removed accordingly.

  The pipe device 1 and the pipe method using the pipe tool 1 according to this embodiment have the pipe body 12 and the distal end portion 3 of the pipe body 2 in the opening 17 of the drain pipe 16 even if the drain pipe 16 is deep. All that is required is to open and close the cock 7 on the ground 20. As a result, the opening 17 of the drain pipe 16 is sealed with the rubber body 9 whose diameter has been expanded by the wing nut, and the pressurized liquid W is introduced into the drain pipe 16.

Therefore, the drainage pipe 116 can be easily and quickly passed through at home. Further, even when the distance from the opening 17 of the drain pipe 16 to the clogging 18 is long, or even when the drain pipe 16 has a bent portion, the clogging operation is performed because the pressurized liquid W is an operation source. Has little effect.

  In addition, regarding the tubular body and configuration of the present invention, each shape and connection state is not limited to the actual form described above. On the other hand, as the pressurized liquid of the present invention, water is most preferable from the viewpoint of easy availability, low cost, safety, preparation of post-treatment, etc., but other than water, for example, vegetable oil, glycerin, ethylene glycol, or other liquids may be used. Absent.

The invention's effect

  As described above, according to the through-tube tool and the through-tube method according to the present invention, even in a deep drainage pipe, the tip of the pipe body is inserted into the opening, and the rubber body is pressed into the drainage pipe and sealed. After that, you can operate on the ground. Thereby, the pressurized liquid can be introduced into the drain pipe. Accordingly, the drainage pipe can be easily and quickly passed through at home. Further, even when the distance from the opening of the drain pipe to the clogging is somewhat long or when the drain pipe has a bent portion, the clogging can be removed by the action of the pressurized liquid alone.

  It is a block diagram which shows the through-tube tool which concerns on one actual form of this invention.   It is principal part sectional drawing which shows the state which inserted the said through-tube tool in the drain pipe.   It is a front view of the said pipe passing tool.   It is a right view containing the partial cross section of the said tube-connecting tool.   It is a left view of the said tube-pipe tool.   The principal part sectional view of the above-mentioned pipe passing tool is shown.
