Description of the Invention: [Technical Field] The present invention relates to a structure of an airbag anti-reverse device, and more particularly to a gating device provided inside an air bag nozzle, and the anti-reverse device is matched with a coupling member outside the air nozzle The relative structure inside the airbag and the airtight structure of the anti-reverse device make the result of the anti-reverse better—to achieve the requirement of airtightness. [Prior Art] . The application of the general airtight back-up device is based on the end of the hard material object. The reverse device has a certain airtight effect, such as the "fuel gasification wheel transfer device" No. 88220495 for steel. The structure of plastic anti-airtightness is widely used. It has not changed much in the structure, and the structure must be assembled or made difficult by the structure of the rigid material. It is used in the structure of soft airbags or airbags. Therefore, the backstops currently used in general airbags or airbag structures are mostly provided with an airtight cover on the air nozzles of airbags or airbags. However, this cover structure is very easy to fall off due to Shiya & 'the airtight effect can not be effectively achieved. Therefore, some operators have other anti-reverse devices on the gas nozzle, and there are many forms, but these are not necessary. The structure of the device is very simple, and there is no need to achieve the effect of airtightness; ^#83212751 "Compressive bag structure for clothes", the structure of the anti-reverse is very: the "easy" is directly by the bag of the exhaust Body sheet bonding, that is, the knot Y is the structural stability of this difference, a slight pressure or rub off, at the exhaust gas, namely a gas-tight and can not easily open by the effect. 5 1343891 In addition, the "backstop valve and the packaging bag having the check valve and the manufacturing device of the packaging bag" are gambling, and the structure of the reverse structure (4) of the plurality of materials overlaps each other, and the structure thereof The airtightness also depends on the airtightness of the fit between the sheets, as well as the "Multi-section clamping air sealing body" No. 4016 = multi-section bending scale * production line red effect, this - structural stability It is also very limited. For example, No. 95219〇28 “Enhanced air-sealing body for side buffer function” ^ is also a design with a backstop structure, but the structure of the job is still in the form of a bag-like point. The airtightness of the fit is very limited, so there is a need for improvement. "Another inspecting the soft (4) or the anti-reverse structure of the silk structure, such as the 812th sun-filled milk-proof and comfortable cap", there is another inflatable device, which is more compatible with the structure of the anti-reverse structure. On the upper and the tube body is connected to the air bag to form the anti-reverse structure; Zhuang..., [Summary of the invention] The inventor of the present invention has carefully studied and accumulated many years of various gas-reverse structure products.

The diameter and the restriction portion 311 of the main member 31 and the positioning portion (1) can be in a form in which the large diameter is sequentially arranged to be smaller, so as to correspond to the degree of the inclined portion 8 ^, that is, the limit portion 311 has the largest circular diameter, and the stopper 32 Second: Positioning. When the stopper 32 is fitted with the stopper 4 to be airtight, that is, as shown in FIG. 4, the elastic member 33 generates a pulling force pp to the main member 31, and the Hela force Pp is transmitted to the restricting portion 311. Even if the limiting portion 311 generates a push-up force on the stopper 32, since the stopper portion 4 is formed into a taper slope of $'!, the force of the § stopper 32 is pushed up via the stopper & The inclination generates the force-returning push-back member 32, that is, the horizontal force Ph' in the direction of the main member 31, so that the sea-stop member 32 is not only pressed against the stopper portion 4 at the outer diameter but also with the restricting portion 311 and the positioning. The space between the portions 312 creates a certain tightness, so that the main member 31, the stopper 32 and the stop portion 41 can produce an airtight effect; and at the same time, the positioning portion 312 can also cover the air nozzle 2 at the same time. The vent hole 22 on the raft is used to achieve multiple airtight effects. The slope of the expansion of the stop portion 41 can be between 0 and 90 degrees outside the axis of the stop portion 41, wherein the shape of the expansion at an angle of 15 to 45 degrees is the angle of expansion closer to the horizontal angle. In a preferred embodiment of the invention, when the outward expansion angle is less than 15 degrees, it is susceptible to the effect of the air pump. In summary, the structure of the case is uncovering the structure of the anti-reverse device, and the special design has been "having the availability of the industry". There is no doubt that, in addition, the characteristics of the touch are revealed in the work of Benzai. Before the application, I have not seen it in various publications, nor have I been controlled by it.
