Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil supply pipe connection port provided for receiving oil supplied from a separate oil tank through an oil supply pipe into an oil combustion heater main body.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a connection port of an oil supply pipe of this kind is provided at an outer side end of a metal pipe 3 on a body side connected to an oil leveler 2 provided in an oil combustion heater body. The part itself is plastically worked into the shape of the nipple 4 so that only the rubber tube is connected to the tip (including the case where the nipple 4 is welded to the metal tube 3), or as shown in FIG. In some cases, an external threaded connection port 7 was attached to the end of the side metal pipe 3 by welding or the like so that only the flared separate oil tank side metal pipe 14 was connected using the cap nut 6.

As shown in FIG. 5, when a rubber pipe is connected to the male screw connection port 7, a flared rubber pipe connecting nipple 8 is attached using a cap nut 6 as shown in FIG. , To which a rubber tube could be connected.

[0004] As shown in FIGS. 7 and 8, a separate oil tank side metal pipe 14 is connected to the metal pipe connection portion 11 of the rubber pipe metal pipe common connection port 16 provided at the end of the main body side metal pipe 3. An oil tank side rubber pipe 15 separately attached to the rubber pipe 15 attached to the cap nut 6 or the rubber pipe connection portion 12 of the connection port 16 is also used.
Some were attached using a band 5.

[0005]

Among the above-mentioned conventional examples, the end of the metal pipe 3 on the main body side shown in FIG. 4 is formed into a nipple 4 dedicated to a rubber pipe. However, there is a problem that an adapter of another piece must be interposed when connecting the two.

Further, when the rubber pipe 15 is connected to the male screw connection port 7 as shown in FIG. 6, a nipple 8 for connecting the rubber pipe has to be separately provided.

Further, as shown in FIGS. 7 and 8, when the metal pipe 14 on the separate oil tank side is connected to the metal pipe rubber pipe common connection port 16, the size of the rubber pipe 15 on the separate oil tank side is specified. Therefore, the outer diameter of the rubber tube connecting portion 12 of the metal tube / rubber tube common connection port 16 is limited accordingly, and there is a problem that a metal tube having an inner diameter smaller than the size cannot be connected. Was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is provided at an outer portion of an oil-fired heater main body and is provided with a metal pipe or a rubber pipe on a separate oil tank side. An oil feed pipe connection port for connecting to an oil feed pipe, a metal pipe on the main body side and a metal oil pipe on a separate oil tank side that communicate with an oil leveler in an oil combustion heater main body at one end and a part thereof. A metal pipe connection part with a specific slope was formed on the periphery to connect the pipe, and a male screw part for a cap nut was formed, and a part was flared to connect a rubber oil supply pipe An oil feed pipe connection port of an oil fired heater was characterized by forming a rubber pipe connection.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention having the above-described structure, a metal pipe connection portion is formed by giving a specific inclination to one end and a part of the periphery of a common connection port for a metal pipe and a rubber pipe.
By forming a helical groove to form a male screw portion for a cap nut, the metal pipe on the main body side and the metal pipe on the separate oil tank side communicating with the oil leveler in the oil combustion heater main body are smaller than the conventional inner diameter dimensions. The rubber tube is connected by forming a rubber tube connection part with flared processing on a part of the other side so that the rubber tube is connected. It is in the state of.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view of an embodiment of the present invention, 1 is a main body of an oil-fired heater, 2 is an oil leveler for supplying a fixed amount of oil to a combustion section (not shown), Reference numeral 3 denotes a main body-side metal pipe having one end connected to the oil leveler 2 and the other end facing the outer shell of the main body 1. These components are exactly the same as those described in the conventional example. 9 is the metal tube 3 on the main body side
15 is a metal pipe / rubber pipe shared connection port attached to an end of the main body outer shell side, and 15 is a separate oil tank side rubber when the oil feed pipe connected to the metal pipe / rubber pipe shared connection port 9 is made of rubber. Reference numeral 5 denotes a hose band for fixing the separate oil tank side rubber pipe 15 to the metal pipe rubber pipe common connection port 9, and is specifically as shown in FIGS.

FIG. 2 is a cross-sectional view showing a case where an oil supply pipe on the side of the separate oil tank in one embodiment of the present invention is made of metal, and FIG. 3 is a side view of the side of the separate oil tank in one embodiment of the present invention. FIG. 6 is a cross-sectional view showing a case in which the oil supply pipe is made of rubber;
6 is a cap nut for fixing the main body side metal pipe 3 and the metal pipe rubber pipe common connection port 9, and 10 and 10 are cap nuts 6, 6.
Is a male screw part to be fitted. Reference numeral 14 denotes a separate oil tank-side metal pipe of the oil supply pipe connected to the metal pipe rubber pipe common connection port 9, and reference numerals 11 and 11 correspond to the flared portions of the metal pipe 3 and the separate oil tank-side metal pipe 14. To be connected
It is a tapered metal pipe connection part with a specific inclination.
Reference numeral 12 denotes a rubber pipe connecting portion to which the separate oil tank side rubber pipe 15 is connected when the oil pipe on the separate oil tank side is made of rubber.

Here, the dimensions of the outer diameter and the inner diameter at one end of the metal pipe 14 on the separate oil tank side are adjusted to the conventional outer diameter of 8.
From 8 mm and 7.2 mm inner diameter to 8 mm outer diameter and 6.4 mm inner diameter are set to dimensions that can be easily connected.

Next, an embodiment of the present invention will be described with reference to FIG.
When the oil feed pipe is made of metal as in the above, the main body side metal pipe 3 is connected to the rubber pipe connection portion 12 at one end of the metal pipe rubber pipe shared connection port 9.
So that the flared portion of the main body side metal tube 3 matches the metal tube connection portion 11 of the metal tube / rubber tube common connection port 9 and then fixed with the cap nut 6 to connect the metal tube / rubber tube common connection At the other end of the opening 9, the flared portion of the separate oil tank side metal pipe 14 is matched with the other metal pipe connection section 11 and then fixed with the cap nut 6 to complete the connection.

When the oil feed pipe is made of rubber as shown in FIG. 3, the metal pipe rubber pipe common connection port 9 is turned left and right in FIG. The flared portion 3 is fitted with the metal pipe connection portion 11 and then fixed with the cap nut 6. At the other end of the metal pipe rubber pipe shared connection port, the rubber pipe connection port 12 is connected to the separate oil tank side rubber pipe 15. After being inserted into the tip, it is fixed with the hose band 5 to complete the connection.

Thus, even if the oil feed pipe connected to the metal pipe rubber pipe common connection port 9 is either the separate oil tank side metal pipe 14 or the separate oil tank side rubber pipe 15, a special adapter is provided. Oil can be supplied to the oil-fired heater main body 1 by simply connecting it immediately without using any other means.

[0017]

As described above, according to the present invention, the metal pipe on the main body side and the metal pipe on the separate oil tank side can be connected to ones smaller than the conventional inner diameter to some extent. The width can be widened, and even if the oil supply pipe on the separate oil tank side is made of metal or rubber, a special adapter etc. is used by reversing the connection of the metal pipe rubber pipe shared connection port It is now possible to supply oil to the oil-fired heater directly and easily without any connection.
