Description

Technical Field

[0001] The utility model belongs to the technical field of land surveying and mapping, and particularly relates to a surveying instrument adjusting bracket for multi-topography national land space surveying and mapping. Background Art

[0002] Land resource management refers to a series of activities for planning, surveying, managing, and supervising land resources. Its purpose is to rationally utilize and protect land resources, and promote the sustainable utilization and development of land resources. Therefore, the surveying and mapping of national land is particularly important. Only accurate surveying and mapping data can effectively ensure the effective implementation of policies for land planning and governance.

[0003] After retrieval, a surveying and mapping device for land management with the prior art publication number CN221258414U is provided with a guide post and a guide ring. When the fixed plate is unfolded, the guide ring moves on the guide post. When it is unfolded to the maximum limit, the connecting plate fixes the fixed plate and will not move, with relatively high stability. At the same time, it is provided with a locking bolt and a limit hole to play a role in adjusting the height, reducing the situation of large deviations during surveying and mapping, and having relatively high practicability.

[0004] In the above solution, although the use of the guide post, guide ring, connecting shaft, and connecting plate can play a stabilizing role, it also has certain constraints, that is, the adjustment of the support angle of the unfolded fixed plate is simultaneous and synchronous, and the support angles of all fixed plates are consistent. Therefore, when facing different terrains, such as surveying and mapping on slopes or terrains with large slopes, a stable support effect cannot be achieved.

[0005] After retrieval, a surveying and mapping device for land consolidation with the prior art publication number CN216383431U also has the above-mentioned defects. Through the setting of the support assembly, through the connecting rod, telescopic bracket, sliding rod, sliding sleeve, support seat, and anti-slip nails, it is convenient to connect the support assembly and the fixed disk, reducing the connection difficulty between the telescopic bracket and the fixed disk, and at the same time making the connection between the telescopic bracket and the fixed disk more stable, thereby improving the stability between the surveying instrument and the support assembly. The support angle between the fixed disk and the telescopic frame can only be controlled and adjusted synchronously and consistently, and the support adjustment of the telescopic frame cannot be carried out separately for the slope.
