Description

[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting tool for connecting a supply hose to a supply pipe, and more particularly to a so-called wire for connecting a hose and a metal pipe for supplying a liquid or a gas. It is an object of the present invention to be able to easily and reliably connect and fix without using a tool tightened at a line.
[0002]
2. Description of the Related Art Generally, in order to connect a supply hose of this kind with a metal pipe by fitting them together, a connection portion is wound around the metal pipe with a metal wire called a number line, and further tightened by using a tool called a Shino. Was.
[0003]
However, it is very time-consuming to use a wire or a tool to fit the above-mentioned supply hose and a metal pipe or to connect the hoses with a joint pipe, and it takes a lot of skill. It costs. Further, when it is necessary to frequently attach and detach the supply hose and the metal pipe, it is not suitable for tightening using the line.
[0004]
SUMMARY OF THE INVENTION Accordingly, the present invention is to solve the conventional problems and to achieve the object of the invention.
[0005]
A first aspect of the present invention is a connecting tool for communication between a supply hose and a supply pipe, wherein a part in the length direction of the metal cylindrical body is formed along the axial direction, and a cutout portion is formed in the radial direction. A semicircular lid corresponding to the portion is openably and closably connected via a hinge, and a tightening lever handle is rotatably connected to the main body at a position opposed to the hinge, and a taper is formed on the top surface of the semicircular lid. It is provided with a shape projection.
[0006]
According to a second aspect of the present invention, in a method for connecting a supply hose and a supply pipe using a communication connection tool, a semicircular cover is hinged on a cutout formed in a part of a metal cylindrical main body so as to be freely opened and closed. After connecting the distal end portion of the soft polyethylene hose to the main body in the cut-off portion, close the lid to hold the hose, and attach the lever handle to the tapered projection on the top surface of the lid. The hose is fixed by being pressed while rotating, and one end of a supply metal tube is connected and fixed to the other end of the main body.
[0007]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The length of a metal cylindrical main body is set to twice or three times the outer diameter of a hose. Next, a half part from the one end side in the length direction of the main body is formed along the axial direction along the axial direction to form a cutout portion in the radial direction, and a semicircular lid corresponding to the cutout portion is inserted via a hinge. Open and close. Further, the end of the metal tube is inserted and fixed to the other end of the main body. Then, after inserting the end of the soft polyethylene hose into the main body on the side of the opening portion where the lid is opened, the lid is closed via the hinge to hold the hose, and the lever handle is rotated. The hose is fixed to the main body by pressing the tapered projection on the top surface of the lid, and the hose and the supply metal pipe are brought into communication. When the lever handle is turned in the release direction in this state, the lid is opened with respect to the main body, and the end of the hose comes off the main body.
[0008]
Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a metal cylindrical body, and its length L is set to be about two or three times the outer diameter of the hose or metal pipe to be connected. The inner diameter of the cylindrical body 1 ₁ in the body is set to match to the outer diameter of the hose and metal tube charged. Reference numeral 2 denotes a semicircular lid made of the same material as the main body, and has a length L 'approximately half the length from one end of the main body 1 and extends in the axial direction and forms a cylindrical cutout portion S in the radial direction. In addition, the cover is disposed in the cut-out portion and is connected to the main body 1 so that the cover can be opened and closed by the hinge 3. It is assumed that the side opposite to the hinge 3 is cut by a small amount g on the lid.
[0009]
4 in semicircular top surface of the lid 2, a tapered projection provided toward the longitudinal direction, are molded with serrations 4 ₁ for lever handle slip to the surface if necessary. Reference numeral 5 denotes a lever handle rotatably attached to a bracket 6 integrally formed on the main body 1 on the side opposite to the hinge of the main body 1, and slides and presses on the tapered projection 4 in a closed state. ing. 7 is a metal tube inserted into and fixed to the other end of the metal cylindrical main body 1, 8 is a soft polyethylene hose whose end is inserted into the main body from the open part S at the one end of the main body. It is. Reference numeral 9 denotes a non-slip saw tooth portion provided on the semicircular inner surface of the main body 1 and the semicircular inner surface of the lid 2.
[0010]
[Specific use example]
The length L of the metal cylindrical main body 1 is set to 140 mm when the outer diameter R of the hose 8 is 70 mm, or set to 96 mm when the outer diameter of the hose 8 is 48 mm. The cutout portion S is formed in a cylindrical shape with a length L ′ (70 mm or 48 mm) from one end of the main body 1 and a depth of a radius r ′. A semicircular lid 2 made of the same material as the main body is connected to the main body 1 via the hinge 3 so as to be openable and closable. Then, the end of the metal tube 7 is inserted and fixed to the other end of the main body 1.
[0011]
Then, charged with the ends of the soft polyethylene hose 6 in the body 1 of KetsuJo portion S side open the lid 2, and a small size that the tip in the cylindrical portion 1 in ₁ alpha (5 to 10 mm position) After fitting, the lid 2 is closed and the hose is held, the lever handle 5 is rotated to press the tapered projection 4 on the top of the lid, and the hose is fixed to the main body 1 and supplied with the hose 6. The metal tube 7 enters a communication state. In this case, since the side opposite to the hinge 3 of the lid 2 is shaved by an amount g smaller than the semicircle, the tightening force is increased by that amount.
[0012]
When the lever handle 5 is rotated in the release direction in this communication state, the lid 2 is opened with respect to the main body 1, and the end of the hose 8 can be detached from the main body 1.
[0013]
【The invention's effect】
The present invention having the above configuration has the following effects. That is, it is possible to simply and reliably connect and fix various supply hoses for liquids and gases to supply pipes without using a metal wire called a so-called wire or a tool tightened by the wire.
