Description

Technical Field

[0001] This utility model relates to the field of ultrasonic test block depth groove measurement technology, specifically to an ultrasonic test block depth groove measurement tool. Background Technology

[0002] In ultrasonic flaw detection technology, determining flaw detection sensitivity, displaying detection distance, evaluating defect size, and testing the combined performance of instruments and probes are all achieved using test blocks. A characteristic of ultrasonic flaw detection is using test blocks as a reference for comparison. While depth indicators or calipers are generally used to measure the depth of holes and grooves in test blocks, many holes and grooves in the test blocks are small in size or diameter, making measurement inconvenient. Furthermore, some larger holes and grooves are difficult to support, necessitating an ultrasonic test block depth measurement tool.

[0003] The existing patent, CN217465635U, entitled "Digital Depth Gauge," discloses a digital depth gauge comprising a mounting plate. One side of the mounting plate has a mounting groove, the inner wall of which is threaded with a mounting bolt. A mounting sleeve is fixedly connected to the top of the mounting plate, and a positioning bolt is located on one side of the mounting sleeve. A sliding groove is formed on the top of the mounting plate, and a measuring bracket is slidably connected to the inner wall of the sliding groove. This digital depth gauge includes a mounting plate, mounting sleeve, positioning bolt, measuring scale, sliding groove, and measuring bracket. By mounting the mounting plate on the measuring bracket, it can move along the measuring bracket via the sliding groove. After movement, the mounting plate can be fixed to the measuring bracket by the positioning bolt. The height of the mounting plate can be adjusted according to daily usage needs, and the measurement results can be recorded by observing the values ​​of the measuring scale and the digital display device, facilitating adjustment of the depth gauge's measurement range to meet daily usage requirements.

[0004] The above-mentioned device installs the mounting plate on the measuring bracket, and the mounting plate can move on the measuring bracket by means of the sliding groove. After moving, the mounting plate can be fixed on the measuring bracket by the positioning bolt. However, some holes are large, and the extension base hole needs to be used frequently, which makes the operation more troublesome and has a lower range of applicability. It cannot meet people's needs well. In view of the above situation, technical innovation is carried out on the basis of existing depth groove measuring tools. Utility Model Content

[0010] Furthermore, an extension rail is installed inside the lower part of the measuring base, and the extension rail is slidably connected to the measuring base.

[0011] Furthermore, a support block is installed at the outer end of the extension rail, and the support block is welded to the extension rail. The extension rail slides outward to increase the distance between the two support blocks, thus providing a larger support range.

[0012] Furthermore, fastening knobs are installed on the left and right sides of the front end of the measuring base, and fastening knobs are threadedly connected to the measuring base. Rotating fastening knobs loosens the extension rail, and the extension rail slides outward to increase the distance between the two support blocks. Rotating fastening knobs fixes the extension rail.
