Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction engineering surveying and mapping support frame. Background Art

[0002] Construction projects refer to the engineering entities formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities.

[0003] During the construction process, it is often necessary to use a surveying instrument to survey the construction site. Generally, the surveying instrument will be installed through a support that is easy to carry. Traditional supports are generally composed of a foldable structure for easy carrying. During the folding process, the support legs will be brought together. However, in order to prevent the support legs from loosening during carrying, they are generally fixed by binding. However, this requires binding and unbinding operations every time they are used, which is very troublesome. Although there are also methods such as using spring pins to achieve simple storage positioning, these structures are similar to the automatic opening structure of automatic umbrellas, but after long-term use, it is found that the ends of the spring pin structures are worn during subsequent folding, and it is difficult to achieve stable storage operations.
