Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detectors, in particular to an anti-strong light irradiation device for an ultrasonic flaw detector. Background Art

[0002] An ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument. It can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects inside workpieces. Since many non-destructive detections involve on-site ultrasonic detection, under strong outdoor light irradiation, it is difficult for the human eye to clearly see the digital ultrasonic display screen. In order to be able to see the display screen clearly, therefore, a light-shielding cover for the display screen is proposed.

[0003] During the use of the existing anti-strong light irradiation device for ultrasonic flaw detectors, it can usually only block the sunlight from the top, and it is not convenient to block the sunlight from the side, resulting in it being difficult for the detector to clearly observe the images and data information displayed by the flaw detector, so that the detection data deviates. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the existing technology that it can only block the sunlight from the top, and it is not convenient to block the sunlight from the side, resulting in it being difficult for the detector to clearly observe the images and data information displayed by the flaw detector, so that the detection data deviates, and to propose an anti-strong light irradiation device for an ultrasonic flaw detector.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an anti-strong light irradiation device for an ultrasonic flaw detector, including an ultrasonic flaw detector assembly. An adjustable light-shielding component is arranged on the top of the ultrasonic flaw detector assembly, and side light-shielding components are arranged on both sides of the ultrasonic flaw detector assembly. The ultrasonic flaw detector assembly includes an ultrasonic flaw detector body. The side light-shielding components include two side light-shielding plates. Sliding grooves are installed on both sides of the ultrasonic flaw detector body. The side light-shielding plates are movably arranged inside the sliding grooves. Springs are installed on the inner sides of the sliding grooves. Pull rods are installed inside the springs. Limiting grooves are formed on the sides of the side light-shielding plates. One end of the pull rod is installed inside the limiting groove.

[0006] Preferably, the adjustable light-shielding component includes a rotating shaft. A top light-shielding plate is installed on the outer side of the rotating shaft. Hydraulic telescopic rods are symmetrically installed between the top light-shielding plate and the ultrasonic flaw detector body. Rotating seats are installed at both ends of the hydraulic telescopic rods.

[0007] Preferably, through grooves are formed on the sides of the sliding grooves. One end of the pull rod penetrates through the through grooves.

[0008] Preferably, a positive magnet is installed on the top of the top light shield, a negative magnet is installed on the top of the positive magnet, and a splicing light shield is installed on the top of the negative magnet.

[0009] Preferably, a display screen is installed on the side of the ultrasonic flaw detector body, and a plurality of buttons are distributed on the side of the ultrasonic flaw detector body.

[0010] Preferably, a connector is installed on the top of the ultrasonic flaw detector body, a wire is connected to the top of the connector, a detector is installed at one end of the wire, rotating shafts are installed at both ends of the ultrasonic flaw detector body, and a support frame is installed on the outside of the rotating shafts.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0012] 1. In the present utility model, by pulling the pull rod outwards, the spring is compressed under force, and then the side light shield is moved inside the chute.
