Description

Technical Field

[0001] The utility model relates to the technical field of eddy current metal material analysis, and particularly relates to an eddy current metal material analysis sensor. Background Technique

[0002] The eddy current sensor system is composed of three parts: a sensor probe and a housing, a preamplifier, a cable and a connector. The eddy current sensor probe is the part of the sensor that senses the measured signal. It is composed of a rectangular cross-section coil wound on a non-metallic skeleton. The probe head body generally uses high-temperature resistant PEEK engineering plastic (or ceramic), and the coil is sealed therein by "secondary injection molding" to enable the probe to work reliably in a harsh environment. When using the eddy current sensor probe for work, it is usually necessary to use a bracket to fix the probe.

[0003] The existing eddy current sensor needs to fix the probe on the bracket by means of threaded connection. When fixing the probe, it is necessary to rotate the first nut and the second nut. Such an installation method is relatively cumbersome, and if impurities adhere to the inside of the nut, it is very likely to cause unstable installation connection, thus affecting the subsequent use of the entire eddy current sensor. Therefore, it is urgent to design an eddy current metal material analysis sensor to solve the above problems. Content of the Utility Model

[0024] Specifically, in this embodiment, the sensor body 4 is inserted into the annular shell 13 and the mounting bracket, and then the rotating ring 14 is rotated to make the rotating ring 14 drive the trapezoidal block 15 to move. When the trapezoidal block 15 contacts one end of the slide bar 19, the slide bar 19 is squeezed, wherein one end of the slide bar 19 is arc-shaped. When the trapezoidal block 15 squeezes the slide bar 19, the inclined surface of the trapezoidal block 15 and the arc-shaped surface of the slide bar 19 can make the slide bar 19 move along the slide groove 16.
