[0002] Flaw detector probes are important components used in non-destructive testing. They are mainly used to detect internal or surface defects in materials and components without damaging the object being inspected. Flaw detector probes vary depending on the detection principle and application scenario.

[0003] Currently, flaw detector probes have low flexibility and cannot be bent, limiting their application range. They are also difficult to inspect curved parts, resulting in significant errors and numerous blind spots during inspection, which reduces the accuracy of the inspection and is not conducive to current use.

[0022] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0023] Please see Figure 1-4 In this utility model, a flexible deformable high-precision probe for a magnetic flux leakage flaw detector includes a flexible shell 3. The interior of the flexible shell 3 is provided with a flexible silicon steel magnetic conductive sheet 9. A set of probe chips 10 is connected to the bottom surface of the flexible silicon steel magnetic conductive sheet 9. A plug 11 is connected to the back of the flexible shell 3. A probe wire 12 is plugged into the plug 11. An electrical adapter 6 is connected to the upper surface of the flexible shell 3.

[0024] In this embodiment, the flexible shell 3 includes a flexible base layer 301, the inner wall of which is connected to a composite elastic layer 303, and the inner wall of the composite elastic layer 303 is connected to a silicone layer 302. The flexible base layer 301, the composite elastic layer 303 and the silicone layer 302 facilitate the formation of a multi-layer flexible structure that can adaptively bend and deform according to the curved surface shape. The inner wall of the flexible shell 3 is connected to a sound insulation layer 8, and the inner top wall of the sound insulation layer 8 is connected to the upper surface of the flexible silicon steel magnetic sheet 9. The sound insulation layer 8 facilitates the suppression of external vibration and interference.

[0025] In this embodiment, a protective cover 5 is fitted on the outer surface of the electrical adapter 6. The bottom surface of the protective cover 5 is connected to the upper surface of the flexible shell 3. The protective cover 5 is used to protect the electrical adapter 6. A set of openings 7 are provided on the front of the protective cover 5. The number of openings 7 is at least four. The design of the openings 7 is used to facilitate heat dissipation of the electrical adapter 6. A wear-resistant polyurethane protective ring 1 is provided on the bottom of the flexible shell 3. The upper surface of the wear-resistant polyurethane protective ring 1 is connected to the bottom surface of the flexible shell 3. The design of the wear-resistant polyurethane protective ring 1 is used to facilitate wear resistance.

[0026] In this embodiment, a model label 2 is provided on the front of the flexible shell 3, and the back of the model label 2 is connected to the front of the flexible shell 3. The model label 2 is used to facilitate the identification of the probe model. Anti-slip recesses 4 are provided on the left and right sides of the flexible shell 3. The side of the two anti-slip recesses 4 that are close to each other is connected to the left and right sides of the flexible shell 3 respectively. The design of the anti-slip recesses 4 makes it possible to stably pick up the probe during operation.

[0027] Working principle: In use, the probe wire 12 is first connected to the main control system of the magnetic flux leakage flaw detector via the plug 11. Then, the probe chip 10 is attached to the surface of the part to be tested. At this time, the flexible base layer 301, composite elastic layer 303 and silicone layer 302 of the flexible shell 3 form a multi-layer flexible structure that can bend and deform adaptively with the curved surface shape, ensuring that the probe chip 10 is tightly attached to the test surface. The flexible silicon steel magnetic conductive sheet 9 concentrates and conducts the leakage magnetic field to the probe chip 10. After the probe chip 10 converts the magnetic signal into an electrical signal, it is processed by the electrical adapter 6 and transmitted to the detection system. The sound insulation layer 8 suppresses external vibration interference. At this time, the protective cover 5 dissipates heat from the electrical adapter 6 through the port 7.
