Technical Field

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

[0002] A total station is a high-tech measuring instrument that integrates optics, mechanics and electronics. It integrates the functions of horizontal angle, vertical angle, distance (slant distance, horizontal distance), height difference measurement, etc. It can complete all the measurement work on the station by installing the instrument once. A total station usually consists of an electronic angle measurement system, an electronic distance measurement system, a data processing part, a communication interface, a display screen and a keyboard, etc., and has a high degree of automation and versatility.

[0003] After searching, the Chinese patent application number is: CN202110437484.6, which involves a total station, which includes an instrument body and a tripod. The tripod includes a mounting platform for mounting the instrument body and three rotating drums rotatably connected to the lower side of the mounting platform. A support rod for supporting on the ground is slidably embedded in the rotating drum; a first limiting mechanism for limiting and fixing one of the rotating drums is provided on the mounting platform, and a second limiting mechanism for limiting and fixing the support rod is provided on one of the rotating drums; the mounting platform is slidably connected with a sliding rod in the vertical direction, and each support rod is rotatably connected with a rotating rod, and the three rotating rods are rotatably connected to the sliding rod. When the first limiting mechanism limits and fixes the rotating drum, the sliding rod will drive the support rod to slide in the rotating drum through the rotating rod; when the second limiting mechanism limits and fixes the support rod, the sliding rod will drive the support rod and the rotating drum to rotate through the rotating rod, so that the height of the instrument body changes. This application can improve measurement efficiency.

[0004] The above technical solution still has a defect, that is, there is a lack of protection for the total station lens. The lens of the total station is exposed to the outside for a long time and is easily damaged by wind, sun, falls, collisions, etc. In order for the total station to be used normally for a long time, we need to propose a total station.

[0037] See also Figure 1 , Figure 3-4 :

[0038] It also includes a support structure for supporting the main body 1. The support structure includes a support seat 11 corresponding to the fixed seat 2, and three groups of legs. The support seat 11 is installed at the bottom of the fixed seat 2, and the three groups of legs are hinged to the bottom of the support seat 11. A threaded groove 9 is provided at the bottom center of the fixed seat 2, and a threaded boss 12 corresponding to the threaded groove 9 is provided at the top center of the support seat 11. The threaded boss 12 is threadedly installed inside the threaded groove 9 and is positioned by a fixing screw. A positioning screw hole 10 is provided at the bottom of the fixed seat 2 on one side of the threaded groove 9, and a through hole 13 for the fixing screw to pass through is provided on one side of the threaded boss 12 of the support seat 11.
