The purpose is to provide.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a cut groove 2 is provided on the outer peripheral edge of the operation ring 1 whose main body is a circular lid, and a circular recess 3 is formed on the upper surface of the operation ring 1 to form a hole in the center. Open. Insert the rubber ring 5 in the center of the bottom of the gas introduction main pipe 4 integrated with the upper burner part, insert the gas introduction end ring 6 in the lower part, and operate the bottom collar part 7 of the gas introduction main pipe 4. It is inserted into the circular recess 3 of the ring 1, and the convolution frame projection 13 is formed on the inner frame of the lower surface of the operation ring 1. In the lower frame of the operation ring 1, the confined semicircular projection groove is formed. A connection attachment 8 having a container receiving guide ring fixing projection 16 is provided at one end of the frame 14 so that the operating ring 1 can be rotated left and right by screwing the connection attachment 8 into the bottom flange 7 from the screw hole 15 on the lower surface. It is characterized in that it is provided so as to be engaged with the connection attachment 8. In addition, the gas introduction main pipe 4 of the burner portion, which is fitted on the upper surface of the operation ring 1, is made independent, and the male screw portion 12 is formed on the outer peripheral surface of the upper portion of the gas introduction main pipe 4, and the male screw portion 12 is formed. The feature is that various burning appliances can be attached tightly.

[0005]

[Action]

 According to the present invention, a combustion instrument is attached to the gas introduction main pipe 4 attached to the upper surface of the operation ring 1 which is the main body, and the container receiving guide ring of the connection attachment 8 is attached to the notch of the container receiving guide ring 10 of the cassette gas cylinder 9. By fitting the fixing protrusion 16 and twisting the operation ring 1, the connection attachment 8 engages with the operation ring 1 and tightly adheres to the container receiving guide ring 10 on the upper part of the cassette gas cylinder 9 and the cassette gas cylinder. The nozzle portion 11 at the tip of 9 can be connected in close contact with the gas introduction end ring 6. Further, the notch groove 2 provided on the outer peripheral edge of the operation ring allows the combustion appliance to be attached firmly and easily to the cassette gas cylinder without slipping the hand.

[0006]

【Example】

 1 to 4 show an example of a cassette gas cylinder connection hole plate to be mounted in the cassette gas cylinder of the present invention, the main body of which has a circular lid shape, and a non-slip groove 2 on the outer peripheral edge. The operation ring 1 with a hole in the center is provided with clamping frame projections 13 on the four sides of the inner frame of the lower surface, and in the lower frame of the operation ring 1, four convolutions are made on the disk-shaped lower surface. The connection attachment 8 provided with the container receiving guide ring fixing protrusion 16 is inserted into one end of the semicircular protrusion lacking groove frame 14 and screwed into the bottom flange 7 from the screw hole 15 on the lower surface to connect. When the attachment 8 is provided, the operation ring 1 does not fall off and can be rotated left and right, and the container receiving guide ring fixing protrusion 16 is inserted into the cut portion of the container receiving guide ring 10 provided in the cassette gas cylinder 9. When the operating ring 1 is twisted, The tightening frame projection 13 provided at the position tightens the tightening semicircular projection lacking groove frame 14 of the connection attachment 8 so as to be tightly attached to the container receiving guide ring 10 of the cassette gas cylinder 9. The nozzle part 11 at the tip is in close contact with the gas inlet end ring 6 and the gas outlet conduit is shortened, and the cassette gas cylinder and the operation ring 1 are kept tightly attached even when used at various angles during use. Therefore, it can be used without the risk of gas leakage or fire extinguishing during use. In addition, the reduced number of parts makes it lighter and easier to transport, and the structural simplification has made it easier to put it on and can be used for camping, outdoor activities and disasters. Can also exert great power.

Next, an example of a specific configuration that is internal to the present invention will be shown. Main gas inlet pipe Brass 1 Rubber ring Rubber 1 Gas inlet end ring Brass 1 Operating ring PA resin 1 Connection attachment PA resin 1 Tightening screw Steel 2

It should be noted that the above-described configuration example is an example, and the configuration is not limited to this, and the configuration such as the shape can be changed according to the application. Further, the dimension (mm) of the cassette gas cylinder connection hole body of claim 1 of the present invention is about 62 (diameter) x 12 (height). It is about 62 (diameter) × 52 (height).

[0009]

[Effect of device]

 The present invention has the following effects due to the above configuration. A connection attachment was provided by forming a locking frame protrusion on the lower surface of the operation ring, which is the main body, and in which the locking semicircular protrusion groove and the container receiving guide ring fixing protrusion are provided. Therefore, by inserting the connection attachment into the container receiving guide ring of the cassette gas cylinder and turning the operating ring, the connecting hole plate of the present invention is integrated with the container receiving guide ring of the cassette gas cylinder. At the same time, it can be easily connected. In addition, by making the gas introduction main pipe part of the combustion equipment integrally installed on the upper part independent, various combustion equipment can be attached and replaced on the upper part, and of course it can be used for camping and outdoor activities. It can also be used as an emergency life-saving tool in the event of a disaster.
