Description

Technical Field

[0001] The utility model relates to the technical field of geographic information surveying and mapping, in particular to a distance measuring device for terrain surveying and mapping. Background Art

[0002] Surveying and mapping refers to the determination, collection and drawing of the shape, size, spatial position and attributes of natural geographical features or artificial facilities on the surface. Distance measurement refers to the work of measuring the length of the line connecting two points on the ground. What usually needs to be measured is the horizontal distance, that is, the length of the projection of the line connecting the two points on a certain level surface. It is one of the elements to determine the planar position of the ground point and is one of the most basic tasks in surveying work. What usually needs to be measured is the horizontal distance, that is, the length of the projection of the line connecting the two points on a certain level surface.

[0003] A Chinese patent with publication number CN209927125U is retrieved, which discloses a distance measuring device for geographic information surveying and mapping. By rotating the second rotating rod, the first gear meshing with the second gear drives the electric telescopic rod to rotate together, so as to facilitate the adjustment of the measuring angle of the telescope laser rangefinder. By extending and retracting the electric telescopic rod, it is convenient to adjust the measuring height of the telescope laser rangefinder, thereby achieving the effect of improving the accuracy of the measurement data, thereby effectively solving the problem that the telescope laser rangefinder is generally used for outdoor distance measurement. However, the existing telescope laser rangefinder is measured by the user holding the instrument in hand during use, which may easily cause the instrument to fall off from the hand, causing damage to the instrument. At the same time, due to the shaking of the hand during hand-held measurement, the measurement result is likely to be inaccurate.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The measuring angle of the telescope laser rangefinder can be adjusted by rotating the gear, but the ground where the box is placed may be uneven. The overall tilt of the box makes it impossible for the telescope laser rangefinder to maintain a horizontal level for measurement, and the surveying and mapping data is not accurate enough. In addition, the second rotating rod is set at the bottom, and the telescope laser rangefinder is at the top. It is difficult to control the rotation of the second rotating rod while understanding the adjustment of the measuring angle of the telescope laser rangefinder. The disassembly operation of the telescope laser rangefinder is also relatively complicated, and the operating space is too small, which reduces the use efficiency of the distance measuring device for terrain surveying and mapping.

[0008] In some embodiments, the four corners of the outer wall of the bottom end of the base are provided with card slots, the card slots are all hemispherical, the card blocks are all spherical, and the card blocks are all adapted to the size of the card slots.

[0011] The utility model provides a distance measuring device for terrain surveying and mapping through improvement, which has the following improvements and advantages compared with the prior art:

[0012] First, the utility model is provided with a box body, a hydraulic rod, a telescope laser rangefinder, a sleeve, an inner rod, a wheel and a grip. The grip arranged at the top pushes the rotating rod to rotate, and the gear 1 at the bottom drives the meshing gear 2 to rotate, thereby driving the hydraulic rod, the circular plate and the telescope laser rangefinder to rotate, and the surveying angle is adjusted. When the telescope laser rangefinder needs to be disassembled for use, the telescope laser rangefinder is directly twisted to make the base press the block in the circular plate, and the block shrinks under the action of the spring, and the telescope laser rangefinder is no longer limited. The telescope laser rangefinder can be pulled out for use. Whether the box body is horizontal can be detected by a level measuring instrument, and the box body can be adjusted to the horizontal by controlling the extension of the bottom wheel.

The disassembly and assembly of the telescope laser rangefinder itself only requires twisting and rotating, and the operation is simpler and more convenient, thereby improving the use efficiency of the distance measuring device for terrain surveying and mapping.

[0013] Second, the utility model is provided with a fixed rod, a protective cover and a circular plate. The protective cover fixedly connected to the fixed rod on the top of the circular plate protects the telescope-type laser rangefinder. When the hydraulic rod controls the circular plate to descend, the protective cover just blocks the inlet and outlet, thereby reducing the possibility of the surveying and mapping structure being affected by external factors when not in use, and improving the safety of the distance measuring device for terrain surveying and mapping.
