[0047] The structure of the gas valve structure in the utility model and the effects it can produce are now described in detail as follows with reference to the accompanying drawings, with a preferred embodiment of the present application.

[0048] First see Figure 1 , Figure 2 and Figure 3As shown, the air valve structure of the present application includes a first body 1, a second body 2, a spring 3, a sliding body 4, an umbrella-shaped body 5 and a third body 6. The first body 1 is in a ring shape, and a space 11 is formed inside. A ring plate 12 is arranged at the bottom of the space 11, and one or more grooves 13 are arranged on the inner edge surface of the ring plate 12, and the groove 13 is arranged slightly inclined. The second body 2 is used to be matched with the bottom of the first body 1. The second body 2 includes a bottom plate 21, a tube 22 is arranged on the top of the bottom plate 21, a screw thread 221 is arranged on the outer edge of the tube 22, and the screw thread 221 is used to match the groove 13; one or more notches 222 are opened on the tube 22; and one or more guide rails 224 are arranged on the inner edge of the tube 22, and the guide rails 224 are arranged along the axial direction of the tube 22; and one or more protrusions 223 are arranged on the outer edge of the top of the tube 22. The spring 3 is assembled on the top of the bottom plate 21 of the second body 2. The sliding body 4 is assembled on the top of the spring 3, a through hole 41 is penetrated in the center of the sliding body 4, and one or more guide rods 42 are connected to the bottom of the sliding body 4, and the guide rods 42 are used to match the guide rail 224. The umbrella-shaped body 5 is assembled on the top of the sliding body 4. A column 51 is provided at the center of the bottom of the umbrella-shaped body 5. The column 51 passes through the through hole 41. The third body 6 is provided with a flat plate 61 at the bottom. A hollow column 62 is connected upwardly to the top of the flat plate 61. One or more side plates 63 are transversely provided on the side of the hollow column 62. The bottom of the third body 6 is connected to the top of the ring plate 12 of the first body 1. In addition, one or more recesses 64 are provided at the bottom of the third body 6. The recess 64 is used to be tightly connected with the protrusion 223.

[0049] When assembling, first assemble the umbrella-shaped body 5 with the sliding body 4, then make the sliding body 4 cooperate with the second body 2 to clamp the spring 3, and screw the second body 2 into the groove 13 of the first body 1 from bottom to top, and then make the second body 2 and the third body 6 form a connection relationship through the engagement of the recess 64 and the protrusion 223.

[0050] When an inflatable cushion 7 is inflated internally, as Figure 4 , using an inflatable unit 9 as an air source, injecting gas through the hollow cylinder 62, the gas will pressurize the umbrella-shaped body 5, thereby compressing the spring 3, and the air will enter the internal air chamber 71 of the inflatable cushion 7 through the notch 222, so that the inflatable cushion 7 is filled with air for easy use.

[0051] When an inflatable cushion 7 is deflated internally, as Figure 5By rotating the two side plates 63 in a specific direction by fingers, the third body 6 is rotated, and the second body 2 is simultaneously rotated and moved upward along the groove 13 until the original joint between the first body 1 and the third body 6 is separated, and the air originally located in the internal air chamber 71 of the inflatable cushion 7 will escape toward the external space 72 through the notch 222 to achieve the purpose of deflation.

[0052] This application has the following advantages:

[0053] 1. The gas valve structure in this application is detachable, which is convenient for maintenance and replacement of internal parts;

[0054] 2. The air intake and exhaust are integrated into the same structure, which is convenient for application and saves costs;

[0055] 3. The airtight structure design of the U-shaped sliding body 4 and the C-shaped umbrella body 5 is combined, which can achieve an airtight effect when locked to prevent gas leakage;

[0056] Fourth, the structure of the umbrella-shaped body 5 plus the spring 3 structure can reduce air backflow, and when the inflation flow rate is reduced to the return value of the spring 3, it can play a check effect;

[0057] 5. When the side plate 63 is rotated, the air release function can be achieved, and the operation is convenient;

[0058] Sixth, there will be no problem of parts coming loose when rotating the side plate 63 to perform the deflation operation;

[0059] 7. The umbrella-shaped body 5 is equipped with a guide rail 224 that allows it to be raised and lowered, so that it will not flip over during longitudinal movement, thereby preventing the airtightness from being lost;

[0060] 8. The design of the concave portion 64 on the second body 2 and the third body 6 and the protrusion 223 being tightly connected can reduce the concern that the spring 3 and the sliding body 4 and the umbrella-shaped body 5 will loosen from each other;

[0061] 9. The sliding body 4 cooperates with the second body 2 to clamp the spring 3, so as to ensure that the spring 3 is straight up and down, and reduce the skewness and the like.

[0062] Although the present invention is described through the above embodiments, its form and details can still be changed without departing from the spirit of the present invention and can be understood by those skilled in the art. The above preferred embodiments of the present application are only one of the ways in which the principle of the present application can be specifically implemented, but are not limited to this and should be defined in accordance with the scope of the claims of the present application.
