[0005] Furthermore, the connecting sealing assembly includes an inner ring, an upper sealing ring, and a lower sealing ring, wherein:

[0006] The inner ring is fixedly connected to the inner wall of the bottom cylinder, and the upper sealing ring and the lower sealing ring are both fixedly connected to the inner wall of the bottom cylinder, and are respectively located at the top and bottom of the inner ring.

[0007] Furthermore, the outer wall of the bottom cylinder is provided with a bottom ring, and the outer wall of the bottom ring is fixedly connected with anti-slip rings, which are arranged vertically at equal intervals.

[0008] Furthermore, the top of the top cylinder is provided with a top cover, and the bottom of the top cover is provided with an inner groove, which is arranged in a ring shape.

[0009] Furthermore, the outer wall of the top cylinder is provided with an external thread, the inner wall of the top cylinder is provided with an internal thread, the inner wall of the inner ring is provided with a bottom thread, and the inner wall of the inner groove is provided with a top thread.

[0010] Furthermore, the top thread inside the inner groove is threaded to both the internal thread and the external thread.

[0011] Furthermore, a limiting ring is fixedly connected to the top of the bottom cylinder, and the inner diameter of the limiting ring is smaller than the inner diameter of the upper sealing ring.

[0012] Furthermore, the outer wall of the top cover is provided with anti-slip ridges, which are arranged in a ring.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows:

[0014] (1) The inner ring inside the bottom cylinder and the bottom thread provided on its inner wall can be connected to the valve, and the sealing effect at the connection is increased by the upper sealing ring and the lower sealing ring to avoid air leakage.

[0015] (2) The internal and external threads facilitate connection with other valves. When not connected, the top of the top cylinder can be sealed by the top cover to further ensure the sealing effect.

[0016] (3) The anti-slip ridges and anti-slip rings can increase the friction during use and improve the effect of use. Attached Figure Description

[0023] like Figure 1-2 As shown, a valve stem adapter includes a bottom cylinder 1 and a top cylinder 2. The top cylinder 2 is fixedly connected to the top of the bottom cylinder 1 and their interiors are connected. It also includes a connecting sealing assembly, which is disposed inside the bottom cylinder 1 and the top cylinder 2.

[0024] The flexibility of use is improved by connecting the sealing assembly for valve stem conversion.

[0025] like Figure 1-4As shown, for easy conversion, the connecting sealing assembly includes an inner ring 3, an upper sealing ring 4, and a lower sealing ring 5. The inner ring 3 is fixedly connected to the inner wall of the bottom cylinder 1. The upper sealing ring 4 and the lower sealing ring 5 are both fixedly connected to the inner wall of the bottom cylinder 1, and are respectively located at the top and bottom of the inner ring 3. The top cylinder 2 is provided with a top cover 8. The bottom of the top cover 8 is provided with an inner groove 9, which is arranged in a ring shape. The outer wall of the top cylinder 2 is provided with an external thread 10, the inner wall of the top cylinder 2 is provided with an internal thread 11, the inner wall of the inner ring 3 is provided with a bottom thread 12, and the inner wall of the inner groove 9 is provided with a top thread 13. The top thread 13 inside the inner groove 9 is threadedly connected to the internal thread 11 and the external thread 10.

[0026] The inner ring 3 can be quickly connected and used by the bottom thread 12 and the top cylinder 2 external thread 10 and internal thread 11.

[0027] In order to limit the installation position of the inner ring 3, a limiting ring 14 is fixedly connected to the top of the bottom cylinder 1. The inner diameter of the limiting ring 14 is smaller than the inner diameter of the upper sealing ring 4.

[0028] The bottom cylinder 1 has a bottom ring 6 on its outer wall, and anti-slip rings 7 are fixedly connected to the outer wall of the bottom ring 6. They are arranged vertically at equal intervals. The top cover 8 has anti-slip protrusions 15 on its outer wall, and they are arranged in a ring.

[0029] In practical use, by screwing on the anti-slip ring 7 on the outside of the bottom ring 6, the bottom cylinder 1 can be connected to the valve stem through the bottom thread 12 on the inner wall of the bottom ring 6. The limiting ring restricts the installation position of the bottom cylinder 1. The upper sealing ring 4 and the lower sealing ring 5 wrap around the outer wall of the valve stem, providing a good sealing effect. When not in use, the top cover 8 is installed on the top cylinder 2 through the top thread 13 inside the inner groove 9. When switching to use, the top cover 8 is unscrewed, and the connection and switching can be made through the external thread 10 or the internal thread 11.
