[0002] Detect cracks or defects inside metal materials or parts. Common flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, eddy current flaw detection, gamma ray flaw detection and other methods. Ultrasonic flaw detection is a method of inspecting part defects by using the characteristics of ultrasonic energy penetrating deep into metal materials and reflecting at the edge of the interface when entering from one section to another. When the ultrasonic beam passes from the surface of the part through the probe to the inside of the metal, it will generate reflected waves when encountering defects and the bottom of the part, forming pulse waveforms on the fluorescent screen. The location and size of the defect are determined based on these pulse waveforms.

[0003] However, the fluorescent flaw detection lamp in the prior art still has some shortcomings. For example, when installing the traditional flaw detection lamp lens, many locks need to be unlocked to replace the lens, which is extremely inconvenient and cannot be replaced quickly. Therefore, the prior art needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] The rear side wall of the lens hoop 5 is provided with a mounting tube 10, the outer wall of the mounting tube 10 is provided with an external thread 11, the interior of the lens holder 4 is provided with an internal thread 8, and there is a thread fit between the internal thread 8 and the external thread 11, so that the lens is assembled by means of a threaded connection;

[0024] The inner wall of the lens hoop 5 is evenly installed with limit blocks 6, and the outer wall of the fluorescent lens 3 is provided with a limit groove 13, and the limit blocks 6 are installed in the limit groove 13. When the fluorescent lens 3 is installed in the lens hoop 5, the limit blocks 6 are inserted into the limit groove 13, thereby improving the connection strength;

[0025] The side wall of the lens holder 4 is rectangular and has a mounting hole 9, and the front side wall of the flaw detection lamp body 1 is rectangular and has a threaded groove. A bolt body 12 is screwed into the mounting hole 9 and the threaded groove. The positions of the mounting hole 9 and the threaded groove correspond to each other, so that the lens holder 4 is installed to the lens mounting position of the flaw detection lamp body 1 by the bolt 12.

[0026] A circular groove 123 is formed at the lower end of the bolt body 12 , and a bolt rod 121 is fixedly mounted at the middle section of the lower end of the circular groove 123 .
