In use, it helps ensure the safe operation of water supply and drainage pipelines. With its ease of operation and accurate measurement, the pipe wall gauge has become a key piece of equipment for maintaining pipeline safety and extending its service life.

[0003] Existing thickness measuring tools, such as vernier calipers and micrometers, require manual operation to measure the wall thickness of PVC pipes. This operation is somewhat slow and reduces measurement efficiency. Therefore, an improved thickness measuring tool is needed to solve the above-mentioned problems.

[0004] A search of existing technical literature revealed a patent application with application number 201220727832.X, entitled "Pipe Wall Thickness Measuring Micrometer." This patent discloses a pipe wall thickness measuring micrometer that can conveniently measure the pipe wall thickness at various locations and has a simple structure. However, this patent has issues such as somewhat slow operation. Utility Model Content

The measuring scale 23 is connected to both sides of the slider 22. The outer side of the measuring scale 23 is slidably connected to the inner side of the slide groove 101. Indicator marks 105 are provided on both sides of the first clamping head 21. The arrows of the indicator marks 105 point to the zero mark of the measuring scale 23.

[0020] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, a first clamping head 10 is provided on the front side of the clamping handle 1, and a handle 11 is provided on the rear side. A first clamping opening 104 is provided on the first clamping head 10. A second clamping head 21 is provided on the front side of the measuring component 2. A second clamping opening 211 is provided on the second clamping head 21. The first clamping opening 104 and the second clamping opening 211 are symmetrically fitted together for clamping the pipe wall. A sliding groove 101 is provided on each of the outer sides of the first clamping head 10, and a groove 103 is provided on the upper side of the first clamping head 10. A slider 22 is connected to the side of the second clamping head 21 near the groove 103. The slider 22 slides in the groove 103, so that the first clamping opening 104 and the second clamping opening 211 open. A measuring scale is connected to each side of the slider 22. 23. Each measuring scale 23 slides within the groove 101 on that side.

The scale value is fixed, and the indicator mark 105 indicates the measured pipe wall thickness. At this time, the scale value can be read to obtain the pipe wall thickness.

[0021] Example 2 This embodiment further provides supplementary explanation of the thickness measuring ruler proposed in the above embodiment.

[0022] The first clamping head 10 has a fixing head 102 connected to both sides by threads. One end of the fixing head 102 is located inside the slide groove 101 and fixes the measuring ruler 23.

[0023] Specifically, when the slider 22 stops moving, the first clamping port 104 and the second clamping port 211 clamp the tube wall, and the measuring ruler 23 stops moving accordingly.
