Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flaw detector technology, and more specifically, to an ultrasonic flaw detector that is resistant to strong light irradiation. Background Technology

[0002] An ultrasonic flaw detector is a portable industrial non-destructive testing instrument. It can quickly, conveniently, non-destructively, and accurately detect, locate, evaluate, and diagnose various internal defects in workpieces. Since non-destructive testing often involves on-site ultrasonic testing.

[0003] A search revealed application CN202420150227.3, entitled "Anti-Strong Light Irradiation Device for Ultrasonic Flaw Detectors." This application addresses the problem that existing anti-strong light irradiation devices for ultrasonic flaw detectors (application number: 201720814978.0) have a fixed size light-blocking shield, making it inconvenient for operators to adjust the size of the light-blocking plate. This can lead to incomplete light blocking, affecting the operator's use of the ultrasonic flaw detector. The proposed solution addresses this issue by using a combination of the ultrasonic flaw detector, bracket, base plate, rubber pad, block, vertical block, lead screw, nut, light-blocking plate, outer shell, vertical cylinder, and adjustment structure. This allows the device to be used by moving the straight plate to the right, which in turn moves the square plate to the right. The process involves the square plate moving the crossbar to the right, which in turn moves the first inclined block to the right. The first inclined block then moves the second inclined block upwards. After the straight plate is adjusted, the spring moves the crank downwards, which in turn moves the second inclined block downwards. This causes the second inclined block to engage with the first inclined block, thus positioning the straight plate. This allows operators to adjust the size of the light-blocking plate, preventing incomplete light blocking and ensuring proper use of the ultrasonic flaw detector. However, the light-blocking structure of this application is relatively complex and occupies a large volume. While easy to remove, resetting is cumbersome and can be further improved. Additionally, the ultrasonic flaw detector itself is large, making it inconvenient to hold with one hand and limiting its usability. These issues can also be addressed through further improvements.

Figure 1-4 As shown, an ultrasonic flaw detector resistant to strong light irradiation according to an embodiment of the present invention includes an ultrasonic flaw detector body 1, a base 8, and a threaded head 11. The base 8 is fixedly installed on the bottom surface of the ultrasonic flaw detector body 1, and threaded holes 10 are provided on the bottom surface, front surface, and back surface of the base 8. An end plate 6 is fixedly installed on the top surface of the ultrasonic flaw detector body 1, and a central shaft 7 is fixedly connected between the end plates 6. An outer sleeve 2 is provided in front of the front surface of the ultrasonic flaw detector body 1, and a movable plate 3 is connected through the bottom opening of the outer sleeve 2. A friction sleeve 4 is fixedly connected to one end of the movable plate 3 inside the outer sleeve 2, and the friction sleeve 4 abuts against the outer sleeve 2. A connecting plate 5 is fixedly connected to one end of the top surface of the outer sleeve 2. The central shaft 7 passes through the connecting plate 5 and rotates with the connecting plate 5 through a damping bearing 12. The connection, damping bearing 12, is a common structure and will not be described in detail here. During flaw detection, the operator can flip the outer plate 2 and the movable plate 3 to block light. Flipping the outer plate 2 causes the connecting plate 5 to rotate along the damping bearing 12, allowing for multi-angle suspension and easy angle adjustment. At the same time, the operator can pull the movable plate 3 outward and inward to adjust the blocking area. The damping effect provided by the friction sleeve 4 facilitates the positioning of the movable plate 3 and prevents it from moving arbitrarily, thus achieving a good light-blocking effect. Adjustment can be completed simply by flipping the outer plate 2 and pushing and pulling the movable plate 3, making adjustment and use simpler. In addition, the outer plate 2 and the movable plate 3 of this device are thinner and lighter, with a simpler structure, making storage and movement more convenient, further improving the ease of use.

[0030] In one embodiment, a handle 9 is threadedly inserted into the threaded head 11, and one end of the handle 9 is provided with a threaded head 11 that mates with the threaded hole 10. There are three sets of handles 9, and a rubber sleeve is fitted on the outer surface of the handle 9 for easy gripping.

[0031] In one embodiment, the back face of the base 8 has two sets of threaded holes 10, the front face of the base 8 has one set of threaded holes 10, and the bottom face of the base 8 has three sets of threaded holes 10. When handheld use is required, the operator can hold one of the handles 9 for gripping. When placed for use, the operator can rotate and remove the handle 9, insert two of the handles 9 into the two threaded holes 10 on the back face of the base 8, and then insert the remaining handle 9 into the threaded hole 10 on the front face of the base 8, thus forming a stable base 8, which is convenient for placement and use, provides multiple usage methods, and further improves the convenience of use.

[0032] In one embodiment, two sets of end plates 6 and two sets of central shafts 7 are arranged to improve stable connection.

[0033] In one embodiment, the outer cover 2 and the movable plate 3 are made of opaque plastic, which is lightweight, and the outer cover 2 is hollow, which facilitates the movement of the movable plate 3.

[0034] In one embodiment, the friction sleeves 4 are distributed on both sides of one end of the moving plate 3, and the outer wall of the friction sleeves 4 is provided with friction texture. The friction sleeves 4 are made of rubber, which has high friction and good damping effect.

[0035] In one embodiment, the inner wall of the outer jacket 2 has a rough structure to increase friction and further improve the damping effect.

[0036] Working principle:

[0037] During flaw detection, the operator can flip the outer cover plate 2 and the movable plate 3 to provide light shielding. Flipping the outer cover plate 2 causes the connecting plate 5 to rotate along the damping bearing 12, allowing for multi-angle suspension and easy angle adjustment. Simultaneously, the operator can pull the movable plate 3 outwards and inwards to adjust the shielding area. The damping effect provided by the friction sleeve 4 facilitates the positioning of the movable plate 3, preventing it from moving arbitrarily, thus achieving a good light shielding effect. Adjustment can be completed simply by flipping the outer cover plate 2 and pushing / pulling the movable plate 3, making adjustment and use simpler. Furthermore, the outer cover plate 2 and the movable plate 3 of this device are lighter. Thinner and simpler in structure, it is easier to store and move, further improving the ease of use. When handheld use is required, the operator can hold one of the handles 9. When it needs to be placed, the operator can rotate and remove the handle 9, insert two of the handles 9 into the two threaded holes 10 on the back of the base 8, and then insert the remaining handle 9 into the threaded hole 10 on the front of the base 8 to form a stable base 8, which is convenient for placement and provides multiple usage methods, further improving the ease of use.
