Description

Technical Field

[0001] The utility model relates to an air valve, in particular to a bottom-embedded air valve. Background Art

[0002] Inflatable paddle boards are a common type of watersports equipment. Compared to rigid paddle boards, inflatable paddle boards are foldable when deflated, making them easier to transport and store. As a result, they are becoming increasingly popular among watersports enthusiasts. Air pressure is crucial for inflatable paddle boards, as the quality of inflation determines the performance and lifespan of the board. Therefore, the inflation valve is a crucial component of a paddle board.

[0003] The existing inflation valve body will form a bulge on the surface of the paddle board. This bulge not only affects the appearance of the paddle board, but the strong hardness will also affect the user's sports performance and even pose a risk of scratching or accidentally injuring the user.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] like Figure 1-7 As shown together, this embodiment relates to a bottom-embedded gas valve, comprising an injection valve housing 2 and a gas valve cover 1 detachably connected thereto. After the gas valve cover 1 is connected and assembled on the injection valve housing 2, it is in a bottom-embedded state and will not form a protrusion beyond the injection valve housing 2.

[0026] In this embodiment, if Figure 1 、 5 As shown together, the air valve cover 1 is formed with an integrated cover body, a handle portion, and an assembly body. The cover body is adapted to the inner ring diameter of the air injection valve housing 2, so that the air valve cover 1 can be embedded in the air injection valve housing 2; the handle portion protrudes from the upper surface of the cover body, and the handle portion is convenient for the operator to manually tighten the air valve cover 1; the assembly body is located on the lower surface of the cover body and is in the shape of a cylinder extending downward, and a tightening groove 12 is provided on the assembly body.

[0027] In this embodiment, if Figure 1 、 3 As shown in the figure, the inner ring of the injection valve outer shell 2 is matched with the middle shell 3, and the middle shell 3 is equipped with a detachable air valve locking block 4 and an air valve inner bracket 5 fastened by the air valve locking block 4. The inner ring wall of the air valve inner bracket 5 is provided with a tightening protrusion 13 adapted to the tightening groove 12.

[0028] Based on the above structure, there are multiple tightening grooves 12, each tightening groove 12 corresponds to a tightening protrusion 13, and the tightening protrusion 13 is implemented in a manner that it moves to the root position of the tightening groove 12 under the action of external force. Figure 5 As shown, the tightening groove 12 is a guide groove, so that when the tightening protrusion 13 enters the notch of the tightening groove 12, under the external force of the operator, specifically the operator manually twists the air valve cover 1 to move the tightening protrusion 13 to the root of the tightening groove 12, the air valve cover 1 is embedded in the air injection valve housing 2.

[0029] like Figure 2-3 As shown, the outer ring of the middle shell 3 is provided with a number of grooves arranged at equal intervals, and the middle shell 3 is connected to the gas injection valve shell 2 through the grooves. That is to say, the outer ring of the gas injection valve shell 2 is provided with protruding ribs that cooperate with the grooves, and the two are fastened together by plugging.

[0030] like Figure 3 As shown, the maximum axial extension length of the middle shell 3 is longer than the maximum axial extension length of the valve locking block 4, and the non-overlapping position of the middle shell 3 and the valve locking block 4 forms a large sinking cavity 14, which is used to provide avoidance for the lower embedding of the valve cover 1; the inner ring of the middle shell 3 and the valve locking block 4 that contact each other is provided with an internal thread, and the outer ring of the valve locking block 4 and the middle shell 3 that contact each other is provided with an external thread that adapts to the internal thread, so the middle shell 3 and the valve locking block 4 are threadedly connected to each other.

[0031] like Figure 7 As shown, the valve inner bracket 5 is a hollow structure and specifically includes a flat plate portion pressed by the valve locking block 4, a ring opening portion extending upward from the upper surface of the flat plate portion and located in the inner circle of the valve locking block 4, and a skirt portion extending downward from the lower surface of the flat plate portion.

[0032] Preferably, a small sinking cavity 15 is formed on the inner ring of the air valve inner bracket 5, and the small sinking cavity 15 is used for embedding the assembly body of the air valve cover 1. A deflation button 6 located at the axis of the air valve inner bracket 5 is provided in the small sinking cavity 15. The deflation button 6 is inserted into the convex column of the deflation bracket 8, and the outer ring of the deflation button 6 is also sleeved with a spring 7.

[0033] The outer ring of the chassis of the deflation bracket 8 is indirectly connected to the anti-leakage seat 10 through the gasket 9. The anti-leakage seat 10 is covered with a valve filter cover 11, and the skirt of the valve locking block 4 is lowered into the valve filter cover 11.

[0034] The present application discloses a bottom-embedded air valve, in which the air valve covers 1 that are detachably connected to each other can be completely embedded in the space of the air injection valve housing 2 when tightened. Therefore, the air valve cover 1 will not form a bulge, which is more beautiful in appearance, will not affect the user's sports performance, and will further avoid the risk of the air valve cover scratching the user.

[0035] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
