Abstract

PROBLEM TO BE SOLVED: To prevent the erroneous use of a gas connection plug. SOLUTION: A socket fitting part A provided with an annular groove on a straight pipe part is connected to the tip of a rubber hose inserting part B provided with annular irregularities on its peripheral surface. When a gas type quick coupling unit is connected, a gas type quick coupling unit connecting socket S is fitted to the socket fitting part A, on the other hand, when a rubber hose is connected, the tip of the rubber hose is inserted into the rubber hose inserting part B and connected. Therefore, a user can be prevented from erroneously connecting the rubber hose to a socket connecting plug and from feeling inconvenience due to misfitting of the gas appliance and a gas hose of a gas cock when the using place is changed.

2. Description of the Related Art In recent years, a so-called reinforced hose containing a metal reinforcing material is widely used as a gas hose connected to a gas fan heater or a gas stove so that the metal hose will not be drowsed when stepped on. Since this reinforced hose is poor in elasticity and cannot be attached to the plug by expanding the tip like a rubber hose, a quick joint connecting socket S as shown in FIG.
Is attached to its tip. In the socket S, normally, when not connected, the spring 6 presses the valve seat 12 in the socket to close the gas passage, and when connected, the valve body is pressed by the tip of the reinforced hose plug R to open the gas passage. 11 is provided, there is an advantage that raw gas does not leak from the socket S even if the socket S is detached from the plug of the gas device during storage.

However, in the above-mentioned conventional structure, the user may mistakenly connect the rubber hose to the gas equipment to which the quick joint connecting plug R is attached, as in the case of the gas range. In such a case, since the shape of the plug R is not formed into a “bamboo shoot” shape for inserting a rubber hose as shown in FIG. 5, even if the plug R is pressed by the hose clip 14, the frictional force is insufficient. There was a problem in safety. In view of such problems, it is an object of the present invention to provide a structure of a gas connection plug that can be safely inserted and attached to either a rubber hose or a reinforced hose with a quick joint.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a gas connecting plug P according to the present invention. The base end portion outside the drawing is attached to a gas burner built-in device such as a gas fan heater or an infrared gas stove. There is. At the tip of the plug, first, a so-called "bamboo shoot" -shaped rubber hose insertion portion B having annular irregularities on the peripheral surface is formed, and further, a socket fitting portion A is formed at the tip thereof. The rubber hose insertion part B has a shape in which two spherical parts 3 each having a peripheral surface formed by cutting a sphere into a circular shape are overlapped with each other.
An annular recess is formed between them. Socket fitting part A
Is provided with an annular groove 2 into which the metal ball Q of the quick joint connecting socket S is fitted near the tip of the straight pipe portion 1, and as shown in the figure, the outer diameter (Da = 11m
m) is the outer diameter of the rubber hose insertion part B (Db = 11.5 m)
Since it is formed to be slightly smaller than the rubber hose, the socket fitting portion A can be relatively easily passed through when inserting the rubber hose, but this A portion also has an inner diameter (9.
Since it is sufficiently large for 5 mm), it fulfills a gas sealing function.

FIG. 2 shows another embodiment of the gas connection plug P according to the present invention, in which the rubber hose insertion portion B is formed by one spherical surface portion 3 to make the shape compact. In this case, in order to ensure that the rubber hose is held by the hose clip 14, an inclined surface 4 is formed at the rear end of the straight pipe part 1 so that the annular recess for the hose clip 14 to bite becomes large. . Even when the rubber hose is inserted into the plug P, since the outer diameter of the socket fitting portion A is slightly smaller than the outer diameter of the rubber hose inserting portion B as described above, the pushed rubber hose does not fit into the socket fitting portion A. After passing relatively easily, it is press-fitted into the rubber hose insertion portion B.

FIG. 3 shows a state in which the quick joint connecting socket S is fitted in the plug P according to the present invention. Springs 6 and 7 are provided on the inner and outer surfaces of the peripheral wall 5 forming the body of the socket S, respectively. The valve actuating ring 8 and the operating ring 9 are slidably inserted, and a through hole 10 is provided at the tip of the peripheral wall 5, and the metal ball Q housed in the through hole 10 serves as a valve. It is sandwiched by the operating ring 8 and the operating ring 9. At the rear end of the valve operating ring 8, the valve body 1
1, the valve body 11 is normally in pressure contact with a valve seat 12 which is annularly projected on the inner circumference of the peripheral wall 5 to shut off the gas passage.

When the plug P is now inserted into the socket S, the valve actuation ring 8 is pushed into contact with the tip of the plug, and when not connected, the spring 7 biases the spring 7 through the step portion of the operating ring 9. Metal ball Q that was pressed inward
Fits into the annular groove 2 at the tip of the plug, so that the plug P and the socket S are engaged with each other. Further, at this time, the valve operating ring 8 is retracted so that the valve element 11 integrally provided at the rear end of the valve operating ring 8 is separated from the valve seat 12 projecting on the inner periphery of the peripheral wall 5 and opened. Valve to allow fuel gas to flow through the reinforced hose. Next, in order to remove the socket S from the plug, the operating ring 9 is attached to the spring 7
The metal ball Q, which has been pushed outward by the spring 6 via the inclined surface of the annular groove 2 by the sliding operation against, is extruded from the annular groove 2 and moves to the inner peripheral surface of the operation ring 9. It is received in the recessed portion 13. As a result, the plug P is disengaged from the socket S, and at the same time, the valve actuation ring 8 is returned by the spring 6 and the valve body 11 shuts off the gas passage in the socket S.

As described above, the present invention has the drawback that the conventional quick joint connecting plug R has a slight difference in outer diameter from the rubber hose connecting plug G, and thus is easily misused by the user. Since it has a structure that can be connected to either a reinforced hose or a rubber hose with a single plug,
In addition to preventing users from accidentally connecting the rubber hose to the socket connection plug, the gas hose of the gas equipment and the gas hose of the gas tap do not match when moving or changing the place of use. There is an advantage that you do not feel inconvenienced.
