Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detectors, and more specifically to an adjustable ultrasonic flaw detector light shield. Background Art

[0002] Ultrasonic flaw detectors are suitable for non-destructive testing of metals such as welds and forgings, and some non-metallic materials. When the ultrasonic flaw detector is used in a strong light environment, a light shield is generally required to be installed in correspondence with the flaw detector for easy observation of the display screen. When using the existing light shield for ultrasonic flaw detectors, it is generally necessary to assemble the corresponding flaw detector, which is not convenient for automatic retraction and release. Since the overall length of the light shield is fixed, the light shielding area is fixed; and when in use, the light shield can only provide light shielding protection for the upper and two sides, and its light shielding angle is fixed, which is not convenient to adjust; and when the bottom light shielding mechanism and the upper side light shield are assembled together, there is a lack of a suitable quick locking mechanism.
