Description

Technical Field

[0001] The utility model relates to the technical field of eddy current detection, in particular to a probe structure for an external through-type eddy current detector. Background Technique

[0002] Eddy current detection refers to a non-destructive testing method that uses the principle of electromagnetic induction to non-destructively evaluate certain properties of conductive materials and their workpieces or detect defects by measuring the changes in the induced eddy currents in the workpiece to be tested. In industrial production, eddy current detection is one of the main means to control the quality of various metal materials and a few non-metal conductive materials such as graphite and carbon fiber composites and their products, and occupies an important position in the field of non-destructive testing technology.

[0003] According to a multifunctional external through-type eddy current detection probe structure disclosed on the patent network (authorization announcement number: CN217385324 U), it is described that "the utility model provides a multifunctional external through-type eddy current detection probe structure, including a male detection probe, a female detection probe and a clamping member. The male detection probe and the female detection probe can be spliced together or separated through the clamping member. The male detection probe and the female detection probe include a housing, a detection through hole penetrating both ends is opened in the middle of the housing, and a detection coil for eddy current detection is also arranged on the housing. The center lines of the detection coil and the detection through hole coincide, and the detection coil is electrically connected with a plug connector. When the male detection probe and the female detection probe of the utility model are spliced together, a self-comparative eddy current detection probe is formed, and when separated, a comparative eddy current detection probe is formed, with the functions of two eddy current detection probes, having multifunctional uses such as sudden defect detection, slow-varying defect detection, thickness measurement or material discrimination detection, reducing the user's use cost, improving the detection efficiency, having a simple structure, strong practicability, low production cost, and being easy to use."

[0004] Regarding the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, since the male detection probe and the female detection probe can be spliced together or separated through the clamping member, when the male detection probe and the female detection probe are spliced together, a self-comparative eddy current detection probe is formed, and when the male detection probe and the female detection probe are separated, a comparative eddy current detection probe is formed, with the functions of two eddy current detection probes. However, during actual use, due to positioning through the insertion post and the insertion hole, but the limitation of the insertion post is not stable enough, so when the metal rod to be tested slides, it is not easy to ensure the stability of the probe, thus affecting the detection work. Therefore, it is necessary to improve a probe structure for an external through-type eddy current detector to solve the above problems. Content of the Utility Model

[0031] Furthermore, the positioning component 31 includes a stud 311. The stud 311 is threadedly installed inside the male probe head 2. A connection column 312 is fixedly installed on the back of the stud 311. A connection piece 313 is fixedly installed at the end of the connection column 312 away from the stud 311. A flap 314 is slidably installed inside the female probe head 1, and a connection plate 315 is fixedly installed outside the flap 314, facilitating the connection work between the female probe head 1 and the male probe head 2.

[0032] Further, a sliding groove is provided at a position corresponding to the connecting piece 313 inside the female probe head 1, and the connecting piece 313 is slidably installed in the sliding groove, which facilitates the positioning of the connecting piece 313.

[0033] Further, the limiting component 32 includes a connecting shell 321 which is fixedly installed on the outside of the female probe head 1. A sliding piece 322 is slidably installed on the inner wall of the connecting shell 321. One end of the sliding piece 322 is fixedly installed with a baffle 323. One end of the sliding piece 322 away from the baffle 323 is fixedly installed with a telescopic column 324, and the telescopic column 324 is fixedly installed with the connecting shell 321. A spring 325 is fixedly installed between the sliding piece 322 and the connecting shell 321. A slider 326 is fixedly installed on the outside of the sliding piece 322.

[0034] Further, a through groove is provided at a position corresponding to the slider 326 inside the connecting shell 321, and the slider 326 is slidably installed in the through groove, which facilitates the movement of the slider 326.

[0035] Embodiment 2:

[0036] Please refer to Figure 6 , and in combination with Embodiment 1, it is further obtained that the stabilizing mechanism 4 includes an extension plate 401 which is fixedly installed on the outside of the female probe head 1. An insertion block 402 is slidably installed inside the extension plate 401. A bolt 403 is threadedly installed inside the extension plate 401.
