Description
Technical Field
[0001] The utility model belongs to the technical field of engineering construction, and in particular relates to a fine-tuning mechanism for a surveying and mapping instrument. Background Art
[0002] A surveying instrument is an instrument used for various types of orientation, distance, angle, height, mapping and photogrammetry work during the planning, design, construction and management stages of engineering construction. A surveying instrument generally consists of the surveying instrument itself and a tripod for fixing it. When the surveying instrument is in use, it usually needs to be leveled.
[0003] The existing leveling methods mostly rely on manually adjusting the tripod to achieve leveling. Since the three legs of the tripod need to be adjusted, the process is cumbersome, and the manually adjusted angle will deviate, resulting in a significant reduction in the accuracy of subsequent surveying and mapping. Moreover, since the surveying and mapping reference points need to be moved frequently, and the horizontal degree of the reference points moved each time is different, the height of the legs needs to be readjusted each time they are moved, which is time-consuming and labor-intensive, greatly reducing the efficiency of surveying and mapping. Therefore, we provide a surveying and mapping instrument fine-tuning mechanism. Utility Model Content

Since one end of the adjustment plate is hinged to the inner side of the vertical plate, when the first movable shaft moves upward or downward, it can drive one end of the adjustment plate to move, thereby changing the use angle of the adjustment plate, and the angle is read by the spirit level. When it is adjusted to the appropriate angle, the movement stops, thereby achieving the purpose of fine-tuning.

[0008] By adopting the above scheme, through the setting of two electric telescopic rods, the two clamping plates can be driven to move inward or outward, thereby changing the distance between the two clamping plates, making it easier to clamp surveying instruments of different sizes and preventing the surveying instrument from slipping during the angle adjustment process.
[0009] As a preferred implementation of the fine-tuning mechanism of a surveying and mapping instrument, a power supply box is fixedly connected to the left side of the top of the base plate, and a battery is provided in the inner cavity of the power supply box.

[0012] By adopting the above solution, the bottom plate can be quickly disassembled and assembled on the top of the tripod through the arrangement of the mounting bolts, thereby greatly improving the efficiency of disassembly and assembly.
[0013] As a preferred implementation of the fine-tuning mechanism of a surveying and mapping instrument, one end of the threaded rod is movably connected to a bearing, and one side of the bearing is fixedly connected to the right side of the inner cavity of the shell.
[0014] By adopting the above solution, one end of the threaded rod is limited by the setting of the bearing, so as to prevent the one end of the threaded rod from being suspended in the air and then shaking.
[0015] As a preferred implementation of a surveying and mapping instrument fine-tuning mechanism, a slide groove is provided at the bottom of the inner cavity of the shell, a slider is fixedly connected to the bottom of the threaded sleeve, and the bottom of the slider is slidably connected to the inner wall of the slide groove.
[0016] By adopting the above scheme, the slide block is limited by setting the slide groove, and the threaded sleeve is assisted to move, thereby improving the stability of the threaded sleeve when moving.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The utility model drives the threaded rod to rotate through a motor, drives the threaded sleeve to move horizontally through the threaded rod, drives the second movable shaft to move horizontally through the threaded sleeve, and generates thrust through the second movable shaft in cooperation with the movable rod, thereby driving the first movable shaft to move upward or downward. Because one end of the adjustment plate is hinged to the inner side of the vertical plate, when the first movable shaft moves upward or downward, it can drive one end of the adjustment plate to move, thereby changing the use angle of the adjustment plate, and the angle is read through a level meter. When it is adjusted to a suitable angle, the movement stops, thereby achieving the purpose of fine-tuning.

The utility model can drive the two clamping plates to move inward or outward by setting two electric telescopic rods, thereby changing the distance between the two clamping plates, making it easier to clamp surveying instruments of different sizes and preventing the surveying instruments from slipping during the process of adjusting the angle.

Through the setting of the bearing, one end of the threaded rod 7 is limited to prevent one end of the threaded rod 7 from being suspended and then shaking. The surface of the threaded rod 7 is threadedly connected with a threaded sleeve 8, and the top of the threaded sleeve 8 is fixedly connected with a second movable shaft 9. The second movable shaft 9 and the first movable shaft 4 are hinged through a movable rod 10. The threaded rod 7 is driven to rotate by the motor 6, and the threaded sleeve 8 is driven to move horizontally by the threaded rod 7. The second movable shaft 9 is driven to move horizontally by the threaded sleeve 8. The second movable shaft 9 generates a thrust under the cooperation of the movable rod 10, and then the first movable shaft 4 can be driven to move upward or downward. Because one end of the adjustment plate 3 is hinged with the inner side of the vertical plate 2, when the first movable shaft 4 moves upward or downward, it can drive one end of the adjustment plate 3 to move, thereby changing the use angle of the adjustment plate 3, and the angle is read by the level 11.

Finally, when it is necessary to fine-tune the use angle of the surveying instrument, the motor 6 drives the threaded rod 7 to adjust the angle. Rotate, drive the threaded sleeve 8 to move horizontally through the threaded rod 7, drive the second movable shaft 9 to move horizontally through the threaded sleeve 8, and generate thrust through the second movable shaft 9 in cooperation with the movable rod 10, so as to drive the first movable shaft 4 to move upward or downward.
