DETAILED DESCRIPTION

[0025] The application will be further described in detail below in combination with the drawings of the specification.

[0026] Reference Figure 1 and Figure 2 The embodiment of the application discloses a surveying and mapping instrument positioning device for surveying and mapping engineering. The positioning device body 1;

[0027] The fixing mechanism 2 is installed and fixed on the bottom surface of the positioning device body 1, and the fixing mechanism 2 comprises a lifting rod 3 connected and fixed with the positioning device body 1, an insert frame 4 slidably connected on the lifting rod 3, a rack 5 connected and fixed in the insert frame 4, a driving gear 6 meshingly connected on the rack 5, and the driving gear 6 rotationally connected with the lifting rod 3.

[0028] A drive motor 7 is installed and fixed at the lower end of the lifting rod 3. Both the drive motor 7 and the drive gear 6 are connected and fixed with mating gears 8. The two mating gears 8 are meshed with toothed belts 9.

[0029] When the positioning device body 1 needs to rise during use, the drive motor 7 can drive the mating gear 8, and then the two mating gears 8 can work together with the toothed belt 9. Then another gear 8 will drive the drive gear 6 to rotate, and then the drive gear 6 will mesh with the rack 5 to move relative to each other. Then the lifting rod 3 will rise inside the insertion frame 4. This design can not only stably drive the positioning device body 1 to rise, but also avoid the problem of poor sealing performance caused by gears and racks in the existing technology.

[0030] Reference Figure 3 A support member 10 is installed and fixed at the lower part of the insertion frame 4. The support member 10 includes an insertion strip 11 that is connected and fixed to the lower part of the insertion frame 4. A sliding frame 12 is slidably connected to the insertion frame 4 and the insertion strip 11. Multiple support legs 13 are rotatably connected to the lower part of the sliding frame 12. The support legs 13 are magnetically engaged with the insertion frame 4.

[0031] The support member 10 also includes a spring 14 that is fixedly connected to the inner wall of the sliding frame 12. The other end of the spring 14 is fixedly connected to a limiting rod 15. The limiting rod 15 is slidably connected to the sliding frame 12 and is inserted into the two ends of the insert 11.

[0032] The support member 10 at the bottom of the insertion frame 4 is designed so that when the ground is hard, the limiting insertion rod 15 can be pulled to compress the spring 14 and separate it from the top of the insertion strip 11. Then the support leg 13 can be opened to move the sliding frame 12 downward. After reaching the bottom, the limiting insertion rod 15 can be released. At this time, the spring 14 drives the limiting insertion rod 15 to be inserted into the lower end of the insertion strip 11. In this way, the sliding frame 12 can be positioned after the support leg 13 is opened, thus ensuring the support and fixation of the device on a hard ground.

[0033] A battery is installed and fixed at the lower end of the lifting rod 3, and the battery is electrically connected to the drive motor 7.

[0034] The implementation principle of the surveying instrument positioning device for surveying engineering is as follows: when the positioning device main body 1 needs to ascend in use, the drive motor 7 drives the matching gear 8, then the two matching gears 8 cooperate with the toothed belt 9 to operate, then the other gear 8 drives the drive gear 6 to rotate, then the drive gear 6 meshes with the rack 5 to move relatively, then the lifting rod 3 ascends in the insert frame 4, when the ground is relatively hard, the limiting insert rod 15 is pulled to compress the spring 14 and separate from the upper end of the insert strip 11, then the supporting leg 13 can be opened to move the sliding frame 12 downwards, after reaching the lower end, the limiting insert rod 15 can be released, at this time, the spring 14 drives the limiting insert rod 15 to be inserted into the lower end of the insert strip 11, so that the supporting leg 13 can be opened to ensure that the sliding frame 12 is positioned, so that the device can be supported and fixed on the relatively hard ground.
