Description

Portable survey and drawing frame for land survey and drawing Technical Field The utility model relates to the technical field of land mapping, in particular to a portable land mapping frame. Background In the technical field of land mapping, a mapping frame is an important device for supporting and fixing a mapping instrument, and the performance quality of the mapping frame directly influences the efficiency and accuracy of mapping work. At present, a conventional tripod structure is often adopted for a mapping frame for land mapping, and a supporting plate of the structure can only adjust the length along a fixed direction. In the actual use process, the surveying and mapping frame has a plurality of defects. On the one hand, when the ground of survey and drawing place is uneven, because backup pad angle modulation is limited, be difficult to keep perpendicular when inserting ground awl and ground contact, lead to the surveying and drawing frame to place stability poor, take place to rock easily, and then influence the precision of surveying and drawing appearance measurement data, on the other hand, traditional surveying and drawing frame structure is relatively fixed, can't adapt to different topography and survey and drawing demands in a flexible way, and angle modulation's flexibility ratio is lower, when using under complicated topography environment, needs spending a large amount of time adjustment surveying and drawing frame position and angle, has seriously reduced survey and drawing work efficiency. In addition, traditional mapping frame is bigger, weight is heavier, carries very inconvenient in open-air mapping work, has increased mapping personnel's work burden, also is unfavorable for the high-efficient of mapping work to develop. Therefore, research and development of a portable, flexible-adjustable and stable-placement soil mapping frame becomes a problem to be solved in the technical field of soil mapping. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a portable mapping frame for land mapping. In order to achieve the above object, the technical scheme of the present utility model is as follows: a portable's survey and drawing frame for soil survey and drawing includes: A supporting plate; The U-shaped rotating plates are arranged at the bottoms of the supporting plates in an annular mode, the sealing ends of the U-shaped rotating plates rotate at the bottoms of the supporting plates, the sealing ends of the U-shaped rotating plates and the supporting plates form rotation locking, and fixing columns perpendicular to the inner walls of the U-shaped rotating plates are fixed on the opposite inner walls of the opening ends of the U-shaped rotating plates; The limit bolt is in threaded connection with the fixed column; The support plate is connected in the U-shaped rotating plate in a sliding way, and a track groove for the fixed column to slide is formed in both sides of the support plate along the length direction of the support plate; Wherein: After the angle of the U-shaped rotating plate and the supporting plate is adjusted, the screwing end of the limiting bolt is rotated, and the limiting end of the limiting bolt is propped against the inner wall of the track groove to form locking of the supporting plate.
