Description

Technical Field

[0001] The utility model relates to the technical field of total stations, in particular to a total station with an eye protection device. Background Art

[0002] A total station, or total station electronic distance meter, is a high-tech measuring instrument that integrates optics, mechanics, and electronics. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance), and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical degree disk with a photoelectric scanning degree disk, and replaces the manual optical micrometer readings with automatic recording and display of readings, which simplifies the angle measurement operation and avoids the occurrence of reading errors. Because it can complete all measurement work at the survey station by setting up the instrument once, it is called a total station. It is widely used in precision engineering measurement or deformation monitoring fields such as large-scale ground buildings and underground tunnel construction.

[0003] However, when using a total station in an environment with strong sunlight, the smooth surface of the reference object will reflect part of the sunlight, making it difficult for the operator to adapt to the environment, which reduces the accuracy and efficiency of engineering measurement to a certain extent.

[0028] Preferably, as 2 and Figure 3 As shown, the ends of the fine-adjusting sunglasses 6 and the coarse-adjusting sunglasses 7 are respectively provided with a rotating shaft 10 rotatably connected to the connecting channel 5 to limit the rotation direction of the fine-adjusting sunglasses 6 and the coarse-adjusting sunglasses 7; a convex point 11 is provided on one side of the rotating shaft 10, and the driving block 9 is slidably connected to the rotating shaft 10, and a guide groove 12 slidably contacted with the convex point 11 is provided on the driving block 9. When the driving block 9 slides on the rotating shaft 10, the driving shaft 10 is driven to rotate on the connecting channel 5 through the force generated by the contact between the guide groove 12 and the convex point 11, thereby driving the fine-adjusting sunglasses 6 and the coarse-adjusting sunglasses 7 to rotate on the connecting channel 5, so that the corresponding fan-shaped lenses 8 on the fine-adjusting sunglasses 6 and the coarse-adjusting sunglasses 7 move to the connecting channel 5, thereby intercepting the sunlight reflected by the smooth object, avoiding the strong light from affecting the operator's line of sight, and improving the accuracy and efficiency of engineering measurement.

Through the cooperation between the convex point 11 and the guide groove 12, the ink degree of the combined sunglasses is adjusted, the sunlight reflected by the smooth object is better intercepted, and the accuracy and efficiency of engineering measurement are improved.

[0032] Preferably, Figure 2 As shown, the eye protection device also includes a telescopic cover 21 arranged on the fixing seat 2 and used in conjunction with the objective lens 4, which plays a role in shielding strong sunlight around, preventing strong light from affecting the operator's vision, and improving the accuracy and efficiency of engineering measurement.

The force applied to the fixed block 22 drives the fixed block 22 to reset under the action of the rebound force of the fourth spring 27, so that the other side of the fixed block 22 contacts the limit block 24, thereby limiting the fixed block 22 from continuing to slide, thereby fixing the telescopic cover 21 to prevent the telescopic cover 21 from blocking light when it is dark outside, resulting in poor observation line of sight and affecting the accuracy and efficiency of engineering measurement; in addition, by pressing the limit block 24 to retract it into the guide rod 23, the fixed block 22 can pass through the limit block 24 smoothly, and under the action of the fourth spring 27, the fixed block 22 is pushed to slide on the guide rod 23, so that the telescopic cover 21 is opened to block sunlight, thereby preventing strong light from affecting the operator's line of sight; at the same time, the operating steps of fixing and resetting the telescopic cover 21 are simplified, thereby improving the accuracy and efficiency of engineering measurement.
