Description

[Detailed Description of the Invention] This invention relates to a hose extraction tool, and more specifically, to a tool for extracting a hose fitted into a hose connection ferrule provided on various types of piping, a pot, etc. from the ferrule.

Conventionally, when removing a hose fitted to a cap, the hose end was usually pulled while turning the hose, or by using a screwdriver or the like to pry the end of the hose against the cap. For this reason, when the hose is tightly fitted to the cap, removing the hose becomes difficult and dangerous, and sometimes it is necessary to cut off the end of the hose that is fitted to the cap. A problem will occur if the

In view of the above reasons, the purpose of this invention is to provide a tool that allows the hose to be easily and safely removed from the mouthpiece even when the hose is firmly fitted to the mouthpiece.

An embodiment of this invention will be described below with reference to the drawings.

In a tool for extracting a hose H fitted into a hose connection cap J installed in various types of piping or a pot, etc., the tool body 1 is formed of a flat strip-shaped member with a predetermined thickness, and the center part of the plate surface is There is a hose band in the longitudinal direction (Jubilee type hose band)
A long hole 2 is formed which fits into the knob Ba of the tightening screw B in A.

First and second insertion parts 3 and 4 are formed at both ends of the plate surface of the tool body 1, the first insertion part 3 has the same plate thickness as the tool body 1, and the second insertion part 4 has the same thickness as the tip. It is formed into a wedge shape, with the plate thickness gradually decreasing toward . U-shaped fitting grooves 5, 6 having an opening width slightly wider than the outer diameter of the base J are formed in the center portions of the first and second insertion portions 3, 4, respectively.

In the above configuration, when removing the hose H fitted to the cap J, first, as shown in FIG.
With the elongated hole 2 of the tool body 1 fitted into the
The tightening screw B can be loosened by rotating the tool body 1 in a predetermined direction. Note that if the tightening screw B of the hose band A does not have a knob Ba and a minus groove is formed in the head Ba of the tightening screw B as shown in FIG. The tightening screw B can be loosened by fitting the part into the minus groove of the head Ba of the tightening screw B and rotating it in a predetermined direction.

Next, as shown in FIG. 2, a second
The insertion part 4 is inserted and its fitting groove 6 is fitted into the cap J. Then, as shown in FIG. 3, the end of the hose H comes out of the mouthpiece J by a predetermined amount by tilting the tool body 3 in the horizontal direction in the figure using a lever. After that, the first insertion part 3 is inserted between the end surface of the hose H that has come out of the cap J by a predetermined amount and the flange Ja of the cap J, and the fitting groove is fitted into the cap J.
By tilting the tool body 1 in the left-right direction in FIG. 4 in substantially the same manner as described above, the end of the hose H is further removed from the mouthpiece J. For this reason, the fitting of the hose H to the cap J becomes loose, and after that, the hose H can be easily and safely removed from the cap J by lightly pulling the hose H.

As described above, this invention is a tool for extracting a hose fitted into a hose connection mouthpiece from the mouthpiece, and the tool body is formed of a flat strip-shaped member having a predetermined plate thickness, and both ends of the plate surface of the body are are respectively formed with first and second insertion portions each having a U-shaped fitting groove that fits into the mouthpiece, and of these first and second insertion portions, the first insertion portion has a thickness corresponding to the plate thickness of the tool body. The second insertion part is formed into a wedge shape with the plate thickness gradually decreasing toward the tip, and the center part of the tool body has a length into which the knob of the tightening screw of the hose band is inserted. This is a hose removal tool with a hole formed in it.

Therefore, when removing a hose fitted to a hose connection cap, first insert the wedge-shaped second insertion portion between the flange formed at the base of the cap and the end surface of the hose, and With the fitting groove of the second insertion part fitted into the cap, the tool body is tilted like a lever to allow the hose to come out by a predetermined amount from the cap. Next, the first plate with the same plate thickness as the tool body
By inserting the insertion part between the mouthpiece and the end surface of the hose and tilting the tool body while the fitting groove of the first insertion part is fitted into the mouthpiece, the hose can be further removed from the mouthpiece. Therefore, even when the hose is firmly fitted into the cap, the hose can be easily and safely removed from the cap.

Further, the tightening screw can be tightened or loosened by inserting the elongated hole formed in the center of the tool body into the knob of the tightening screw of the hose band and rotating the tool body in a predetermined direction.

In particular, the first insertion part of the first and second insertion parts is formed with U-shaped fitting grooves at both ends of the tool body, which is formed from a flat strip member with a predetermined plate thickness. The tool body has an extremely simple structure in which the plate thickness remains the same, the second insertion part is formed in a wedge shape with the plate thickness gradually decreasing toward the tip, and a long hole is formed in the center of the tool body. This has the effect that a hose extraction tool can be obtained and can be provided at a low cost.
