[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 4As shown, the wing pitot tube connector includes a static pressure tube 1, the inner wall of the static pressure tube 1 is provided with a total pressure tube 5, the static pressure tube 1 is sleeved on the outer wall of the total pressure tube 5, and a total pressure hole is opened at the center of the front end of the total pressure tube 5. When the aircraft flies forward, the oncoming airflow enters the total pressure chamber through this hole and is blocked and decelerated, and the speed drops to zero. The pressure at the stagnation point is the total pressure. The total pressure chamber transmits the measured total pressure to the relevant flight instruments or sensors and computers through the conduit for calculating the parameters such as the speed of the aircraft flight. The top of the static pressure tube 1 is closed, and many static pressure holes are opened on the side part of the rear where the airflow is not easily disturbed. The static pressure hole is used to sense the local atmospheric static pressure, and the measured static pressure is transmitted through the conduit of the static pressure chamber. By measuring the static pressure, the flight speed and other data of the aircraft can be calculated in combination with the total pressure. A fixed base 2 is provided on the rear side of the outer wall of the static pressure tube 1. The fixed base 2 is used to support the static pressure tube 1 and the total pressure tube 5. A threaded hole is provided at the bottom of the fixed base 2. The fixed base 2 can be installed and connected with the designated mounting hole on the wing. A fixing ring 6 is provided on the upper end of the fixed base 2. A fixing bolt is provided between the fixing ring 6 and the fixed base 2. The fixing ring 6 is detachably connected to the fixed base 2 through the set fixing bolts. The fixing ring 6 fixes the static pressure tube 1 and the total pressure tube 5 to the fixed base 2. A fixed baffle 4 is also provided on the front side of the outer wall of the static pressure tube 1. A positioning plate 3 is also provided on the front end outer wall of the fixed baffle 4 on the outer wall of the static pressure tube 1. The positioning plate 3 and the fixed baffle 4 are both provided with mounting holes in the middle. The static pressure tube 1 passes through the mounting holes in the middle of the positioning plate 3 and the fixed baffle 4. The positioning plate 3 and the fixed baffle 4 are used to be connected to the installation position of the pitot tube, so that the connection between the pitot tube and the wing is more stable.

[0022] It should be noted that the utility model is a wing pitot tube connector. When in use, the total pressure pipe 5 is installed inside the static pressure pipe 1, and the static pressure pipe 1 is passed through the middle of the positioning plate 3 and the fixed baffle 4. At the same time, the positioning plate 3 is mounted on the upper end of the fixed base 2, and the fixing ring 6 covers the upper end of the fixed base 2. The fixing ring 6 is connected to the fixed base 2 by fixing bolts, and then the fixed base 2 is installed at the specified position of the wing, connected and fixed by fixing bolts, and the static pressure pipe 1 and the total pressure pipe 5 pass through the mounting holes in the wing, so that the static pressure pipe 1 and the total pressure pipe 5 can be installed on the wing.
