The present invention relates to an ultrasonic detecting mechanism, and more particularly to an ultrasonic detecting unit and a detecting mechanism.

Ultrasonic detection technology is a commonly used non-destructive detection method, which is often used to detect the mechanical properties or defects of materials, as well as the internal structure and damage of various workpieces. The ultrasonic wave is a kind of mechanical wave, and must be used as a coupling liquid through a medium such as water as a propagation medium of the ultrasonic wave. Therefore, in the conventional ultrasonic detection of the object to be tested, the object to be tested must be placed in the water. The ultrasonic probe is then used to transmit and receive ultrasonic waves in the water for detection.

However, the method of inserting the measured object into the water for ultrasonic detection requires a large coupling fluid storage tank to accommodate a large amount of coupling liquid for providing the entire measured object to be placed in the coupling fluid, and the coupling fluid storage tank. Larger, too much coupling fluid usage. Moreover, this method is not suitable for some products, such as ceramic targets and high-purity metal targets, which are susceptible to oxidation due to contact with water and affect the quality of the target.

For example, in the patent of WO1980002074A1, it discloses a method of coating an ultrasonic probe and a coupling liquid with a wheel-shaped outer casing, and performing ultrasonic pressure detection, so that the surface skin of the wheel-shaped outer casing is in close contact with the object to be tested through the pressing, and the ultrasonic wave is self-wheeled.
