AI Technical Summary
When installing and connecting high-precision wireless transmitters, threaded connections are prone to wear, leading to fluid leakage and affecting sealing.
The system employs a fastening connection structure, including an external connecting pipe, an internal telescopic connector, and a rubber airbag ring. By rotating the threaded rod to stretch or compress the internal telescopic connector, gas can enter or exit the rubber airbag ring, thereby improving the sealing performance.
It improves the sealing performance of threaded connections, makes operation simple and quick, and enhances the practicality of high-precision wireless transmitters.

Abstract
Claims
1. A protective structure for a high-precision wireless transmitter, comprising a mounting and fastening connection structure (4) and a connecting threaded post (5) provided at the bottom of the mounting and fastening connection structure (4); characterized in that An external connecting pipe (9) is provided on the side of the fastening connection structure (4). An internal telescopic connector (13) is provided in the middle of the external connecting pipe (9). A connecting threaded rod (10) is provided on the outer side of the internal telescopic connector (13). A ventilation connecting pipe (14) is connected to the middle of the bottom of the external connecting pipe (9). A rubber airbag ring (12) is provided at the end of the ventilation connecting pipe (14) and near the upper end of the connecting threaded post (5). The connecting threaded rod (10) can stretch and compress the internal telescopic connector (13) by rotating and moving due to the thread action. The air inside the internal telescopic connector (13) will be drawn out or discharged due to stretching or compression. The discharged gas will enter the rubber airbag ring (12) and cause it to expand. Conversely, it will cause the rubber airbag ring (12) to be concave.
2. The protection structure for high-precision wireless transmitters according to claim 1, characterized in that: The inner side of the outer connecting pipe (9) is provided with an internal thread that matches the connecting threaded rod (10).

5. The protection structure for high-precision wireless transmitters according to claim 4, characterized in that: A high-precision wireless transmitter device body (1) is provided on the upper side of the data dial (2), and the high-precision wireless transmitter device body (1) and the data dial (2) are an integral structure.
6. The protection structure for high-precision wireless transmitters according to claim 5, characterized in that: A connecting shaft column (7) is provided on the side of the high-precision wireless transmitter device body (1), and a connecting antenna (8) is connected to the side of the connecting shaft column (7). The connecting antenna (8) is connected to the high-precision wireless transmitter device body (1) by rotating the connecting shaft column (7).
7. The protective structure for a high-precision wireless transmitter according to claim 1, wherein: A connecting guide rod (6) is provided at the bottom middle position of the connecting threaded column (5), and the connecting guide rod (6) is connected to the connecting threaded column (5) by means of threads.
