Hereinafter, with reference to the accompanying drawings with respect to the configuration and operation of the embodiment of the present invention will be described.

Figure 4 is a front view of the automatic time control gas injection device of the present inventors lifejacket and life jacket.

Referring to Figure 4, all the components constituting the gas injection device of the present invention is a built-in and the body 5 is waterproof so that the water is not absorbed, the air inlet of the main body 5 and the life tube and life jacket The connection part 10 which is a part which is combined with 50, the compressed gas cylinder 20 which has the compressed gas sealed and the blower outlet 20a is provided in the upper end, and the gas blown out from the compressed gas cylinder 20 is a tube or a life tube. The gas inlet 15 for ejecting to the air inlet 50 (see Fig. 6) of the main body 5, the inner right end of the main body 5 is coupled to a predetermined ring is rotatable and refracted at a predetermined angle, the compressed gas cylinder Compression stage 25a is provided to compress the gas ejection opening 20a of the head), and a predetermined time is caused by the difference between the force by the first spring 30 and the second spring 35 and the friction gear 45 described later. With the time control bar 25 proceeds to the bottom with the device to operate Consists of a button 40.

In addition, with reference to Figure 5 with respect to the configuration that does not appear in the front view of FIG.

Figure 5 is a left side view of the automatic time control gas injection device of the present inventors lifejacket and life jacket.

Referring to Figure 5, the left side of the gas injection device of the present invention is equipped with a friction gear 45 that rotates in a clockwise direction and has a constant friction force, and the time control rod 25 on the right side of the friction gear 45 Coupling grooves 65 are formed to be coupled.

And, at the bottom there is a button 40 to enable the friction gear 45 to operate. In addition, the part shown by the dashed-dotted line is the only part which protrudes outward of the main body 5, and only the button 40 which makes this apparatus operate is projected outward. In addition, the main body 5 is waterproofed so that water does not seep even when the button 40 protrudes.

The operation of the present invention having the above configuration will be described with reference to FIGS. 4 and 5 as follows.

When the user is coupled to the connection portion 10 to the air inlet 50 of the life tube or life jacket when an emergency occurs and press the button 40 is coupled to the coupling groove 65 of the predetermined position of the friction gear 45 of FIG. The time adjustment bar 25 is moved to the bottom.

Referring to the principle that the time adjustment bar 25 is moved to the lower side, first, the first spring 30 and the second spring 35, which is pulling the time adjustment bar 25 elastically, the difference in the elastic force The elastic force of the second spring 35 is greater.

However, the button 40 is to prevent the time adjustment bar 25 to proceed to the lower end by the elastic force by fixing the friction gear 45. If the button 40 is pressed, the fixing means of the friction gear 45 which stops the time adjusting rod 25 is released, and the friction force of the first spring 30 and the friction gear 45 is the time adjusting rod. 25 prevents progression to the bottom. However, since the combined force of the elastic force of the second spring 35 and the weight of the time adjustment bar 25 exceeds the friction force of the first spring elastic force + the friction gear, it proceeds with a predetermined time to the lower end.

In addition, 1 to 6 seconds shown in the coupling groove 65 of the friction gear 45 shown in FIG. 5 is the compressed gas cylinder 20 adjusts the gas ejection time according to the position where the time adjustment bar 25 is coupled.

That is, when the time control bar 25 is coupled to the position of 6 seconds, when the button 40 is pressed, the time control bar 25 proceeds to the bottom, and the coupling groove corresponding to the 6 seconds of the coupling position is the top. Therefore, the compression stage 25a of the time adjustment bar 25 proceeds to the lower end to compress the ejection opening 20a of the compressed gas cylinder 20 during the time of about 6 seconds. The compression stage 25a of the rod 25 presses the spout 20a of the compressed gas cylinder 20. Accordingly, the liquefied gas stored in the compressed gas cylinder 20 vaporizes the liquefied gas at a large pressure. The gas passed through the gas outlet 15 is injected into the air inlet 50 of the life jacket or the tube through the connection part 10.

Similarly, the position of 3 seconds and the position of 1 second of the engaging groove 65 of the friction gear 45 is such that the compression end 25a of the time adjusting rod 25 pressurizes the outlet 20a of the compressed gas cylinder 20 so that the gas Is the time to erupt. In other words, if it is located at the top, the time is delayed, and if it is located at the bottom, it is faster.

When the gas is injected into the life jacket or the life tube using the device in the above process, the gas is released to the outside again if the stopper is not closed when the device is spaced apart. In order to prevent such a phenomenon will be described with reference to FIG.

6 is an exemplary view for explaining the sealing of the tube connecting portion in the present invention.

The air inlet 50 of a general life tube or life jacket protrudes outward so that air can be injected through a predetermined portion of the tube casing 60 made of a predetermined material. However, as shown in FIG. 6, when the stopper 55 is inserted into the air injection port 50 protruding to the outside, the plug 55 is sealed without closing the plug of the air injection hole 50. The stopper 55 has a rectangular body portion 55-1 and a head portion 55-2 having a triangular pyramid shape in the air inlet 50 direction.

That is, when the gas is injected into the air inlet 50 of the life tube or the life jacket according to Figures 4 and 5, the internal pressure is stronger than the external pressure. At this time, if the air injector of the present invention is separated, the compressed air of the high pressure inside the tube is momentarily discharged to the outside of the low pressure, and is inserted into the air inlet 50 at that moment, and a stopper having a triangular pyramid shape outward ( 55 is pushed out by the pressure so that the plug 55 blocks the inlet of the air inlet 50.

This device is not discarded after one use but can be used more if gas remains according to the designed structure.If the gas is used up, it can be recycled by replacing only the compressed gas cylinder with a new one.

Through all the above processes, the automatic time control gas injection device of the life tube and the life jacket is implemented as intended by the present invention.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, conversions, and modifications are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

As can be seen from the above description, the present invention includes a compressed gas cylinder into which the liquefied gas is inserted so that the air can be instantaneously injected into the life jacket and the life tube, and a friction gear to control the time that the gas is ejected from the gas cylinder. Using the coupling stage and time control rod coupled thereto, the time of gas ejection is controlled according to the coupling position, and by inserting porous material into the tube, the tube is automatically sealed after gas injection. As air can be injected, there is an effect that can control the gas ejection time according to the position of the distress during the third party rescue, the portability, the effect of being compatible with all life tubes, life jackets.
