Technical Field

[0001] The utility model relates to the technical field of quality supervision of civil air defense projects, in particular to a measuring device for quality supervision of civil air defense projects. Background Art

[0002] Civil air defense project quality supervision involves the oversight and inspection of civil air defense projects (such as fortifications and underground shelters) throughout their design, construction, and acceptance phases to ensure they meet appropriate engineering quality standards and safety requirements. This quality supervision requires the use of measuring devices, including depth gauges.

[0003] However, most existing measuring devices for quality supervision of civil air defense projects use a top screw to fix the position of the depth gauge during use, and the outer surface of the depth gauge will be scratched after long-term use. The depth gauge needs to be fixed by rotating the top screw during use, which makes the device inconvenient to use and not practical enough. Therefore, a measuring device for quality supervision of civil air defense projects is proposed to address the above problems. Utility Model Content

[0015] 1. The utility model holds the measuring ruler with one hand and squeezes the handle with the other hand to drive the clamping plate, the clamping block and the clamping pad to disengage the clamping of the measuring ruler. Then, the bottom of the sleeve is brought into contact with the surface to be measured. Then, the measuring ruler is moved with one hand to facilitate the downward movement of the measuring ruler for subsequent depth measurement. After the movement and measurement, the handle is released so that the handle is reset under the action of the rebound force of the squeezed spring. In this way, the clamping plate, the clamping block and the clamping pad are reset to squeeze and clamp the measuring ruler, so that the measuring ruler is positioned after measurement. After the measurement, the measured value can be directly viewed after the ruler is taken out, making the device easy to use.

[0016] 2. The utility model uses a soft sponge material clamping pad to squeeze and clamp the outer surface of the measuring ruler, and wipes the outer surface of the measuring ruler when sliding after the measurement is completed, so as to keep the outer surface of the measuring ruler clean.
