Description

Technical Field

[0001] The utility model relates to a geological surveying ruler capable of fixing the measuring position, belonging to the technical field of geological surveying instruments. Background Technique

[0002] The task of geological surveying is to measure a geological map, also known as geological mapping or geological mapping, which is the projection of the intersection trace of the terrain and geological bodies on a horizontal plane. That is, with a certain scale and various pattern symbols, all geological bodies exposed on the surface are reflected on a plan.

[0003] Geological surveying is commonly used in fields such as mine production and resource exploration, and is a basic technical work for project development. Generally, during geological surveying, when using a tape measure, the phenomenon of the tape getting stuck often occurs due to the too fast retracting and releasing speed of the tape measure. And after the tape is pulled to the designated position, the reel cannot be fixed. When affected by external forces or other factors, the tape is prone to retracting or releasing too much, resulting in a large change in length, thereby affecting the measurement accuracy.

[0004] Chinese Patent Application No. CN213932258U discloses a measuring ruler for geological surveying. This measuring ruler includes structures such as a housing, a support shaft, a reduction motor, and a transmission gear. This measuring ruler can automatically and evenly retract the tape, and the friction between the clamping block and the reel can be adjusted through a push block to control the rotation speed of the reel, reducing the labor intensity of the user. And it can avoid the phenomenon of the tape getting stuck due to the too fast retracting and releasing speed of the tape, and can fix the reel after the tape is pulled to the designated position, avoiding large errors caused by the tape retracting or releasing too much when affected by external forces, and improving the measurement accuracy. In use, this measuring ruler fixes the reel after the tape is pulled to the designated position to avoid large errors caused by the tape retracting or releasing too much when affected by external forces. However, the device is not convenient to fix during use, resulting in the device being prone to move under external forces during the use process, so the stability of the device during use is reduced. And this device is not convenient to limit the retraction of the tape, and when affected by external forces during the use process, the tape is prone to elongate, reducing the measurement accuracy of the device.
