[0002] In the field of aviation, the performance monitoring and safe flight of an aircraft are of great importance, and the pitot tube is one of the key sensors for measuring the speed of the aircraft relative to the air. In order to ensure the accuracy of the airspeed data, the pitot tube needs to be regularly maintained, calibrated or replaced. However, in actual operation, the connection between the pitot tube and other systems is usually complex, especially when multiple air sources or test equipment need to be connected at the same time, the traditional method often involves the use of an adapter with a single interface, which not only increases the difficulty of operation, but also easily leads to unstable connection, thereby affecting the reliability of the measurement results.

[0003] The existing pitot tube adapter has many deficiencies in design:

[0004] There is no independent and easily identifiable operation method for each connection port, making it difficult for field engineers to quickly and accurately complete the connection;

[0005] There is a lack of effective anti-slip design, especially in high-altitude operations or slippery environments, which may increase the risk of accidental falling;

[0006] During carrying, the unused connection port lacks protection measures and is easily contaminated or damaged, thereby affecting subsequent use. SUMMARY

[0007] The technical problem to be solved by the utility model is to provide a pitot tube multi-pass adapter with multiple interfaces, independent identification, and precise alignment for different data measurements. The interface position is sealed and protected, which not only prevents impurities from entering and being damaged, but also prevents the loss of blocked fittings.
