Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting device for a cartridge-type gas cylinder in a combustion device such as a portable gas stove, a portable gas stove, or a portable barbecue maker.

[Prior Art] Portable gas stoves, portable gas stoves, portable barbecue ovens, etc. are removably equipped with gas cylinders filled with liquefied gas, and the liquefied gas is vaporized and burned. After the gas cylinder is used, it is taken out and a new gas cylinder is installed. At this time, the gas cylinder must be securely connected to the flow control valve.

As a mounting device for such a gas cylinder, Japanese Utility Model Application Publication No. 54-94639 discloses that a Z-shaped fixture is provided at a portion of a holder that holds a gas cylinder that corresponds to the bottom of the gas cylinder. It has been proposed that the bottom of the gas cylinder is connected to and removed from the tool.

[Problems with the prior art] In the prior art described above, the gas cylinder is placed on the holder while pressing the end of the fixture, and then the pressure on the fixture is released to set it and take out the gas cylinder. Even when installing or removing a gas cylinder, it was necessary to keep pressing the end of the fixture to remove the gas cylinder and then release the pressure on the fixture. However, there was a problem that the operability was poor.

The present invention solves the above-mentioned problems and aims to provide a gas cylinder mounting device with good operability.

[Means for Solving the Problems] The present invention includes a receiver provided in the container frame to hold the circumferential surface of the gas cylinder, and a flow rate control valve provided on one side of the receiver to which the nozzle of the gas cylinder can be connected. , a gas cylinder setting fitting pivotally connected to the other side of the receiver, the setting fitting having a pivot portion facing the circumferential surface of the gas cylinder and whose axis is orthogonal to the gas cylinder; a first arm part extending on one side of the part and inclined toward the circumferential surface of the gas cylinder and whose end side can come into contact with the circumferential surface of the gas cylinder; and a bottom part of the gas cylinder on the other side of the pivoting part. a second arm part extending slightly more protrudingly and tilting toward the circumferential surface of the gas cylinder; It is configured to include a locking part that can come into contact with the bottom and a pressing part for operation that projects from the other side of the locking part.

[Function] When the gas cylinder is pushed into the receiving body, the locking part fixes it to the bottom of the gas cylinder, and by operating the pressing part, the bottom of the gas cylinder is lifted, allowing easy installation and removal.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a main body of the device, which is a container frame, which is equipped with a burner 2 almost in the center, and forms a storage chamber 4 on one side in which a cartridge-type gas cylinder 3 filled with liquefied gas is installed. 4A is a cover that opens and closes the storage chamber 4.

Reference numeral 5 denotes a metal receiver on which the gas cylinder 3 is placed horizontally. It is composed of a bottom portion 5B and support portions 5C extending in an arc shape on both sides of the bottom portion 5B. A flow control valve 6 with a pressure reducing valve is fixedly installed in the rising portion 5A to take out a predetermined amount of gas from the gas cylinder 3. The flow rate control valve 6 has a communication port 7 at one end that communicates with the gas cylinder 3, and a needle valve 9 in a nozzle pipe 8 that communicates with the communication port 7.
is housed so that it can be moved forward and backward by a knob 10, and the needle valve 9 is attached by caulking so as to freely fit the needle body 11 at the tip with an inclined plane.
A shoulder 13 is provided at the base of the nozzle tube 8 to contact the slope 12 formed on the nozzle pipe 8.
A protruding portion 15 for forming a bulge 4 is provided. 16
17 is a notch formed in the flange of the gas cylinder 3 that engages with the protrusion 5A for positioning, and 18 is a set metal fitting pivoted near the rear end of the receiver 5. The set fitting 18 has a first arm portion 1 which extends to one side and is inclined toward the circumferential surface 3A of the gas cylinder 3, and whose end portion 18A abuts the circumferential surface 3A of the gas cylinder 3.
8B, and the end 18C on the other side is the gas cylinder 3.
A second arm portion 18D extends slightly protruding from the bottom portion 3B and is inclined toward the peripheral surface 3A side.
further extends above the end portion 18C and is inclined toward the bottom portion 3B side.
A locking portion 18E that can be locked on the B is formed, and the pressing portion 1 for operation is formed by bending the locking portion 18E to the rear of the locking portion 18E.
8F is formed. A pivot shaft 19 serving as a pivot portion for pivotally attaching the set fitting 18 is connected to the first and second
The gas cylinder 3 is provided between the arm portions 18B and 18D, and its axis 19A is perpendicular to the longitudinal direction of the gas cylinder 3.

Note that 20 is a pipe connecting the burner 2 and the flow control valve 6.

Next, the operation of the above structure will be explained. First, when installing the gas cylinder 3, put the nozzle 3C of the gas cylinder 3 on the communication port 7, and then
When the entire body is pressed against the receiving body 5, the end portion 18
A is pushed down and the set metal fitting 18 rotates clockwise about the pivot 19. As a result, the locking portion 18E is pressed against the bottom portion 3B, locked and held, and the gas cylinder 3 can be fixed.

For combustion, when the needle valve 9 is fully opened by turning the knob 10, the liquefied gas is supplied to the burner 2 through the nozzle 3C, the communication port 7, the vaporizer tube 14, and the pipe 20, and can be combusted.

Next, after consuming the liquefied gas in the gas cylinder 3,
When replacing a new gas cylinder 3, first press the pressing part 18F, and the setting fitting 18 will align with the pivot 1.
It rotates counterclockwise around 9 as the center of rotation. Therefore, the peripheral surface 3A of the gas cylinder 3 is automatically pushed up by the end portion 18A and released from the locked state by the locking portion 18E. Then, the gas cylinder 3 is taken out from the storage chamber 4, and a new gas cylinder 3 is installed in the same manner.

As described above, the first arm portion 1 has an end portion 18A that can come into contact with the circumferential surface 3A of the gas cylinder 3 on one side of the set metal fitting 18 that is pivotally connected to the rear end of the receiver 5.
8B, and a second arm portion 18D is provided on the other side, and an end portion 1 of this second arm portion 18D is provided.
By providing the locking part 18E and the pressing part 18F on 8E, when installing the gas cylinder 3, the nozzle 3
The gas cylinder 3 can be set by simply applying C to the communication port 7 and pushing the gas cylinder 3, and when taking out the gas cylinder 3, the gas cylinder 3 can be pushed up and taken out by pressing the pressing part 18F.
Gas cylinder 3 can be easily installed and removed.

Further, since the locking portion 18E of the set fitting 18 can always press the bottom portion 3B of the gas cylinder 3, leakage from the nozzle 3C can be prevented.

Moreover, by providing the receiving body 5, the flow rate control valve 6, and the setting metal fitting 18 in one piece, the gas cylinder 3 can be mounted firmly by the combination thereof.

It should be noted that the present invention is not limited to the above-mentioned embodiments; for example, the flow rate regulating valve may be provided with a valve body that uses a spring to maintain a set pressure, and it may also be used in a portable barque maker, etc. Various modifications are possible, such as allowing the receiver to be exposed without providing a protective cover on the outside of the receiver, and furthermore, the setting metal fittings may be made of synthetic resin.
