[0002] Metal material refers to the material with luster, ductility, easy electric conduction, heat conduction and other properties. It is generally divided into two kinds of ferrous metal and nonferrous metal. Currently, when detecting metal material defects, ultrasonic nondestructive testing instrument is usually used, and the ultrasonic nondestructive testing instrument is a detector that does not damage or affect the future use performance or purpose of the material or workpiece. It can find defects in the internal and surface of the material or workpiece. When the ultrasonic flaw detector is used, the probe is usually attached to the surface of the material to be detected, and scanning is performed along the area to be detected. The probe emits ultrasonic waves, and when the waves encounter defects in the material, part of the waves will be reflected back. After the probe receives the reflected waves, it converts them into electrical signals. By analyzing the signals received by the flaw detector, the location, size and nature of the internal defects of the material can be determined. Usually, the defects are displayed on the screen of the flaw detector, which can be further analyzed and evaluated.

A display screen 7 and control buttons 8 are installed on the front of the ultrasonic non-destructive testing instrument 1. A carrying strap 6 is fixedly connected to the left side of the ultrasonic non-destructive testing instrument 1.

[0024] In this embodiment, the carrying strap 6 facilitates the user's carrying of the ultrasonic non-destructive testing instrument 1. By inserting the connector 42 into the connector port 5 of the ultrasonic non-destructive testing instrument 1, the test probe 4 is connected to the ultrasonic non-destructive testing instrument 1, allowing the ultrasonic non-destructive testing instrument 1 and the test probe 4 to be used. After use, the test probe 4, wire 41, and connector 42 can be stored inside the storage cover 31 for protection.

[0025] Example 2:

[0026] like Figures 1-5 As shown, a dustproof mechanism 2 is provided on the left side of the top of the ultrasonic non-destructive testing instrument 1. The dustproof mechanism 2 includes a protective cover 21. The bottom of the protective cover 21 is fixedly connected to the left side of the top of the ultrasonic non-destructive testing instrument 1. A dustproof plate 29 is provided inside the protective cover 21. The bottom of the dustproof plate 29 overlaps the top of the ultrasonic non-destructive testing instrument 1. A connecting block 27 is fixedly connected to the left side of the top of the dustproof plate 29. A lead screw 26 is provided above the dustproof plate 29. The two ends of the lead screw 26 are rotatably installed on both sides of the inner wall of the protective cover 21 through bearings. The middle part of the connecting block 27 is threadedly connected to the outer wall of the lead screw 26. A worm gear 2 is fixedly sleeved on the left side of the outer wall of the lead screw 26. 5. A worm 24 is provided behind the worm gear 25. The worm 24 meshes with the worm gear 25. The bottom end of the worm 24 is rotatably mounted on the lower left side of the inner wall of the protective cover 21 through a bearing. The top end of the worm 24 extends to the top of the protective cover 21 and is fixedly connected to a knob 23. A protective cap 22 is provided on the left side of the top of the protective cover 21. An annular mounting groove is opened on the left side of the top of the protective cover 21. The bottom of the protective cap 22 is threaded into the inside of the annular mounting groove. The knob 23 is located inside the protective cap 22. Guide rods 28 are movably sleeved on both the front and rear sides of the inside of the connecting block 27. The two ends of the guide rods 28 are fixedly connected to the two sides of the inner wall of the protective cover 21.

[0027] In this embodiment, the protective cap 22 is provided to protect the knob 23 and prevent workers from accidentally touching it. If dust protection is required for the connection port 5, the protective cap 22 can be screwed off, and the worm gear 24, worm wheel 25 and lead screw 26 can be rotated by the knob 23. The lead screw 26 drives the connecting block 27 and dustproof plate 29 to move. At the same time, the guide rod 28 is provided to guide the connecting block 27 and dustproof plate 29 horizontally. The bottom right side of the dustproof plate 29 can be moved to the top of the connection port 5 to seal the connection port 5, thereby preventing dust from adhering and accumulating inside the connection port 5.

[0028] In summary, as Figures 1-5 As shown, this non-destructive testing device for metal material defects is used by first unscrewing the protective cover 32, then removing the detection probe 4, wire 41, and connector 42 from inside the storage cover 31, and inserting the connector 42 into the connection port 5 of the ultrasonic non-destructive testing instrument 1 to connect the detection probe 4 to the ultrasonic non-destructive testing instrument 1. At this point, the ultrasonic non-destructive testing instrument 1 and the detection probe 4 can be used. Coupling agent is applied to the metal to be tested, and the detection end of the detection probe 4 is pressed against the surface of the material to be tested. The material is scanned along the area to be tested for non-destructive testing. After the test, the connector 42 can be removed from inside the connection port 5, and the detection probe 4 is placed inside the lower part of the storage cover 31. Then, the round cover 324 is unscrewed, and the wire 41 and connector 42 are passed through the central opening 321 of the protective cover 32. The protective cover 32 is then screwed onto the top of the storage cover 31. The protective cover 32, through the connecting rod 33, causes the limiting ring 34 to press down on the detection probe 4. Above the outer wall, the detection probe 4 is limited, and then the wire 41 and connector 42 are placed inside the storage cover 31 through the opening 321. The round cover 324 is screwed into the opening 321 to seal the inside of the opening 321, thus facilitating the storage and protection of the detection probe 4, wire 41 and connector 42. Since the detection probe 4 is placed inside the storage cover 31 first, and then the wire 41 and connector 42 are placed inside the storage cover 31, it can prevent the limiting ring 34 from pressing on the wire 41 and connector 42 when limiting the detection probe 4. The operator then screws off the protective cap 22 and rotates the knob 23 and worm gear 24. The worm gear 24 drives the worm wheel 25 and lead screw 26 to rotate. The lead screw 26 drives the connecting block 27 to slide on the outer wall of the guide rod 28. The bottom of the connecting block 27 and the right side of the bottom of the dustproof plate 29 move to the top of the connecting socket 5 to seal the top of the connecting socket 5, which can prevent dust from adhering and accumulating inside the connecting socket 5.
