[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 , the utility model provides a technical solution:

[0024] An ultrasonic flaw detector includes a detector body 1, the top of the detector body 1 is fixedly connected to one end of a connecting line 2, the other end of the connecting line 2 is fixedly connected to a detection probe 3, and a ring light 16 is fixedly installed on the outer wall of a mounting base 6. The irradiation direction of the ring light 16 is consistent with the detection direction of the detection probe 3. By setting the ring light 16, the illumination for the operator can be improved under dim light adjustment, so that it is easy to find the detection site for detection.

[0025] It also includes a detection rod 4, a handle 5 is rotatably installed at the bottom of the detection rod 4, a mounting seat 6 is fixedly installed on the top of the detection rod 4, and a detection probe 3 is arranged in the mounting seat 6. By arranging the detection rod 4, it is convenient for the operator to move the detection probe 3 to a higher or narrower area, thereby reducing the difficulty of detecting welds of some steel structures such as bridges, buildings and factories, and facilitating detection; a limit plate 14 is fixedly installed at the bottom of the detection rod 4, and a limit groove 15 is provided inside the handle 5. The limit plate 14 and the limit groove 15 are slidably matched. By arranging the limit plate 14 and the limit groove 15 for use in combination, it is ensured that the handle 5 can rotate normally, and at the same time, the handle 5 and the detection rod 4 are prevented from falling off.

[0026] The adjusting assembly also includes an adjusting component for adjusting the angle of the detection probe 3, the adjusting component includes a mounting seat 6, the detection probe 3 is fixedly mounted on one side of the mounting seat 6, a connecting plate 8 is fixedly mounted on the other side of the mounting seat 6, the connecting plate 8 is rotationally matched with one side of the connecting member 9, the other side of the connecting member 9 is rotationally matched with the rotating seat 10, the rotating seat 10 is fixedly mounted on the top of the adjusting rod 11, the adjusting assembly also includes two groups of sliding rods 12, the sliding rods 12 are fixedly mounted on both sides of the mounting seat 6, the sliding rods 12 are slidably matched with the adjusting grooves 13, the adjusting grooves 13 are opened on both sides of the mounting seat 6, and the adjusting grooves 13 are close to the middle of the mounting seat 6. One end is low and the other end close to the edge of the mounting seat 6 is high. By setting a sliding rod 12 and an adjusting slot 13 for use together, the mounting seat 6 can be rotated while the rotating shaft moves, preventing the mounting seat 6 from interfering with the adjusting rod 11 during the rotation process, thereby ensuring that the mounting seat 6 and the detection probe 3 can rotate normally; the adjusting rod 11 is slidably matched with the bottom of the mounting seat 6 and the inside of the detection rod 4, and the bottom of the detection rod 4 is threadedly matched with the handle 5.
