Description

Technical Field

[0001] The utility model relates to the technical field of a total station bracket, in particular to a total station bracket with a protection mechanism. Background Art

[0002] The total station is a high-tech measuring instrument that integrates optics, mechanics and electronics. It is widely used in deformation monitoring projects in the fields of railways, high-speed railways, foundation pits, dams, slopes, tunnels, tall buildings, etc. In these applications, the total station usually needs to be stably supported on the ground by a bracket so that the staff can perform accurate data measurements. However, there are some problems with the existing brackets, such as a single bottom structure, difficulty in adapting to uneven ground, inconvenience in carrying, and poor stability. In order to solve these problems, a bracket for a total station with a protective mechanism was invented. The design purpose of this bracket is to provide a device that is convenient for stably supporting the total station on uneven ground, while protecting the total station from damage. This bracket may include a mounting platform, a lifting mechanism, a support frame and multiple retractable legs to adapt to the needs of different terrains and ensure the stability and safety of the total station during use.

[0003] The support structure used by most existing total stations is a very simple fixed bracket, which is firmly supported by a single or multiple support columns and has poor protection.
