Description

[Detailed explanation of the idea] The present invention relates to a pressurizing device for supplying and supplying gas.

For example, when sealing oil pipes, gas supply pipes, and water pipes, when lifting and widening heavy objects such as disaster relief, when supplying gas to air bunks, or when supplying tire air to particularly large vehicles. There are various cases where compressed gas is required.

In these cases, what has been considered so far is generally high-pressure gas cylinders, near compressors, and other air pumps referred to in the High Pressure Gas Control Law.

Conventionally, when these air supply means are used to inflate, for example, the above-mentioned air bank, there have been the following inconveniences.

That is, when compressors are used, these devices are relatively large and heavy, and are therefore extremely inconvenient to carry.

Furthermore, when using a compressor, not only does it take a considerable amount of time to be able to supply high-pressure air, but it also has the fatal flaw that it requires a reliable power supply to start the compressor.

However, the air pack described above is not necessarily used in a place where there is a power source, but rather is often used in a place where there is no power source.

Therefore, in such cases, a separate compressor with an internal combustion engine or a power supply vehicle was prepared, or a manual or foot-operated air pump was also used.

However, when using a power supply vehicle, it is an extremely large-scale work, and even when using a manual or foot-operated air pump, it takes a considerable amount of time to supply gas into the air bank. , it can hardly be used for emergency purposes.

The present invention has already attempted to use a large high-pressure gas cylinder that does not require a compressor device or a power source to start it, and connect it to an air pack, but ordinary high-strain gas cylinders are relatively large and weigh considerably. It is extremely inconvenient to carry around, and not only does it require container certification, but it also has the inconvenience of being able to be refilled only at a specific location after use, so it was confirmed that it was ultimately impractical. did.

Therefore, as a result of further research and experiments, the inventor of this invention came up with the idea of using multiple small-sized high-pressure gas cylinders at the same time, which did not require the use of gas cylinders.
f)> also led to the development of a heating device for gas supply that was lightweight and made it possible to instantly supply high-pressure gas.
・Specifically, a movable rod, a plurality of cylinder mounts installed at predetermined intervals on the side or both sides in parallel with the rod, and a plurality of cylinder mounts for adding small gas cylinders, each of which is individually installed. It consists of an opening means for opening the cylinder, a connecting pipe for collecting the gas ejected from each cylinder, and an outlet for sending out the collected gas, and a backflow prevention balloon is installed between the cylinder mounting base and the connecting pipe. is interposed therebetween, and the movable rod is provided with engaging protrusions capable of regulating the operation of the cylinder opening means described above at respective locations corresponding to the small gas cylinders attached to each of the cylinder mounts. Another object of the present invention is to provide a gas supply device characterized in that the operation of the cylinder opening means can be regulated or released by arbitrarily moving the moving rod in its longitudinal direction.

Below, the specific content of the present invention will be explained based on an illustrated embodiment. 1 is a bottom plate, 1a and 1b are bottom plates 1
1c and 1d are side plates planted on the bottom plate 1;
2 is a movable rod that penetrates the side plates 1c and 1d and moves in the longitudinal direction; 3 is a protrusion integrally provided on the movable rod 2 at equal intervals in the longitudinal direction in a zigzag manner from side to side; and 4 is a protrusion on the movable rod 2. The attached locking part 5 is a spring, which is fitted between the locking part 4 and the side plate 1d, and keeps the movable rod 2 constantly connected to the side plate 1.
It is biased in the direction of pushing out in the direction c.

The movable rod 2 has a through hole 6 roughly near the side plate 1C direction,
Roughly, on the side plate 1cK, an operating rod 7 having a protrusion 9 at its tip is rotatably attached to a shaft 8 as a fulcrum, and when the movable rod 2 moves, the through hole 6 portion thereof intersects with the operating rod 1. At this position, the protrusion 9 of the operating rod 1 enters into the through hole 6 to engage and hang therein.

Reference numeral 11 denotes a spring, which includes a protrusion 10 provided on the side plate 1c and a protrusion provided above the shaft 8 of the operating rod 7.
(not shown), and always biases the operating rod 7 in the half-clockwise direction in FIG.

On the other hand, reference numeral 13 denotes a cylinder tray fixedly provided on both sides of the movable rod 2 at equal intervals. A needle 15 is planted in the thin plate at the opening of the gas cylinder to unseal the puncture wound.

Furthermore, 17 is an opening lever, which is a cylinder mounting stand 13.
It is rotatably mounted on a support shaft 16 suspended horizontally at the rear upper position of the base 12 directly below the base plate 12, and in normal times, its tip head 17a is lowered to a position close to the bottom plate 1, and the opposite side is lowered. The handle part 17b is raised upward, and when the handle part 17b is pressed down in the direction of the bottom plate 1 during use, the pricking needle 15 is pushed upward at the same time.

Reference numeral 18 indicates a gas take-off portion integrally added to the side of the stand 130 for mounting the cylinder, and reference numeral 19 indicates a backflow prevention valve.

As shown in FIG. 4, the backflow prevention nozzle 19 consists of a valve external pressure 20, a valve main body 22 screwed into the inside thereof, and a connecting camp 24, and the backflow prevention nozzle 19 is made up of an external valve pressure 20, a valve main body 22 screwed into the inside thereof, and a connecting camp 24. For high pressure, the valve core 23 is extended in the direction of the coupling camp 24 to introduce the supplied pressurized gas, but completely blocks the supply in the opposite direction.

Further, reference numeral 25 indicates a take-out pipe, the tips of which are connected to the main pipe 26, respectively, and the take-out pipe 2
5 and the main pipe 26 constitute a connecting pipe. Furthermore, an outlet 29 is attached to the end of the main pipe 26 on the side plate 1d side.

In addition, 27 shows an opening/closing cock, and 28 shows a pressure gauge.

Therefore, each cylinder is attached to a stand 13 with a small gas cylinder 3.
0 in the upside down direction, and then rotate the operating rod 7 clockwise in FIG.
At the same time as the cover is pulled out, the moving rod 2 moves toward the side plate 1c.

As a result, all the protrusions 3 of the moving rod 2 are removed from the upright position of the head 17a of the lever 17, so that the handle 1 of the lever 1T
7b can be pressed downward, and when the thin plate at the opening of the small gas cylinder 30 located directly above it is unsealed by the puncture needle 15, the high-pressure gas in the cylinder 30 passes from the extraction part 18 through the backflow prevention valve 19 and is rubbed out. It is fed under pressure to the main pipe 26 via the pipe 25.

At this time, if other small gas cylinders 30 are opened one after another, the gas pressure will be increased, and the necessary number of small gas cylinders 30 will be opened depending on the object to which the gas pressure is supplied.

In this case, the gas that has partially passed through the Vc inside the in-pipe 26 will not flow back toward the stand 13 when the cylinder is installed again due to the action of the backflow prevention valve, so any one of the small gas cylinders will have a low pressure. Or, there is no need to worry even if there are places where small gas cylinders are not installed.

The high-pressure gas taken out in this manner is supplied to the target airbag 31 through the outlet 29 while operating the valve cock 27, and is inflated.

Further, the used small gas cylinder 30 is removed from the cylinder mounting table 13 and replaced with a new small gas cylinder.

In addition, when the present device is not in use or when being transported, in order to prevent the handle portion 17b of the lever 17 from being inadvertently pressed in the direction of the bottom plate 1 and opening the small gas cylinder, the movable rod 2 described above is installed. Drill 50 springs and install side plate 1d.
When moved in the direction of , the protrusions 3 on both sides of each lever 7
The protrusion 9 of the operating rod 7 is located directly above the head 17a of the
As a result, the head 17a of the lever 17 is clamped so that the small gas cylinder 30 will not be opened by mistake.

Since the present invention has the above-described structure and function, it is lightweight and compact, making it easy to carry around.Although it does not require a power source to drive it, it is capable of instantaneously supplying high-pressure gas. This makes it possible to use the airbag especially during disaster relief, and it also has various effects such as opening the required number of gas cylinders or replacing or increasing the number of gas cylinders depending on the object to be used.

In the above-mentioned embodiments, the case where the present invention is used to supply high-pressure gas to an airbag has been described, but it goes without saying that the present invention is not limited to these applications and can be used in a wide variety of applications.
