[0032] Example 1: Please refer to Figure 1-3 The utility model provides a technical solution: a land engineering surveying and mapping device, comprising a surveying and mapping box body 1. The top of the surveying and mapping box body 1 is slidably provided with two covers 3;

[0033] It should be noted that a first T-shaped slot 24 is provided at the top of the surveying and mapping box body 1. Covers 3 are slidably mounted on both sides of the first T-shaped slot 24, and handles 4 are fixedly mounted at positions close to the upper end surfaces of the two covers 3. When in use, the two handles 4 are pulled to drive the corresponding covers 3 to move in opposite directions.

[0034] Furthermore, a rectangular groove is provided in the middle of the lower end surface of the two covers 3. A second rack 12 is fixedly mounted on the inner wall of the two rectangular grooves;

Second gears 13 are fixedly mounted on the tops of the two first screw rods 14, and the two second gears 13 are meshed and connected with the corresponding second racks 12. The two covers 3 move in opposite directions to drive the two second racks 12 to move synchronously, thereby driving the two second gears 13 to rotate, and the rotation of the two second gears 13 drives the two first screw rods 14 to rotate.

[0036] The two first screw rods 14 are threadedly connected with support plates 15;

[0037] It should be noted that the support plate 15 includes a support plate body and connecting plates fixedly installed on both sides of the support plate body. The two connecting plates are respectively threadedly connected to the outer surfaces of the two first screw rods 14. The two first screw rods 14 rotate to drive the support plate 15 to move upward.

[0038] The upper end surface of the support plate 15 is provided with a measuring instrument 11 , which is a prior art and will not be described in detail herein.

[0039] Furthermore, the bottom ends of the two first screw rods 14 extend downward from the lower surface of the surveying and mapping box body 1, and the bottom ends of the two first screw rods 14 are fixedly mounted with the first gear 8;

[0040] Specifically, a second T-shaped slide groove 25 is provided in the middle of the lower surface of the surveying and mapping box body 1. Two first movable plates 9 are slidably installed inside the second T-shaped slide groove 25 through two T-shaped sliders. First racks 7 are fixedly installed on both sides of the two first gears 8 corresponding to the opposite surfaces of the two first movable plates 9. The four first racks 7 are meshed and connected with the corresponding first gears 8. The four first racks 7 are slidably connected with the corresponding first movable plates 9;

The four support rods are slidably inserted inside the four sockets 6 respectively. The two first screw rods 14 rotate to drive the two first gears 8 to rotate, and the two first gears 8 rotate to drive the four first racks 7 to move, thereby causing the two first moving plates 9 to move away from each other along the slide groove 10, so that the two first moving plates 9 are close to the corresponding fixed blocks 5, and then clamp the legs 2 to prevent the surveying and mapping box body 1 and the legs 2 from being separated by external forces and causing equipment damage.

[0043] Working principle of embodiment 1: When in use, place the support leg 2 in the measuring area, and insert the four support rods of the support leg 2 into the corresponding four sockets 6 on the surveying and mapping box body 1; pull the two handles 4 to move the two covers 3 away from each other, and the movement of the cover 3 drives the corresponding second rack 12 to move, and the second rack 12 engages with the second gear 13 to make the first screw rod 14 rotate, and the rotation of the first screw rod 14 drives the support plate 15 to move upward along the axis of the first screw rod 14, thereby making the measuring instrument 11 move outside the surveying and mapping box body 1 to prepare for surveying.

[0044] At the same time, the two first screw rods 14 rotate to drive the two first gears 8 to rotate, and the two first gears 8 rotate to drive the four first racks 7 to move, so that the two first movable plates 9 move away from each other along the slide groove 10, so that the two first movable plates 9 are close to the corresponding fixed blocks 5, and then clamp the legs 2 to prevent the surveying and mapping box body 1 and the legs 2 from being separated by external forces and causing damage to the equipment.

[0045] Embodiment 2: Figure 4-Figure 5 A land engineering surveying and mapping device is shown, and the difference between this embodiment and the first embodiment is that:

[0046] The upper end surface of the support plate 15 is provided with a first groove 22. The middle position of the side surface of the support plate 15 is provided with a second groove 10. The second screw rod 18 is rotatably mounted inside the first groove 22;

[0047] It should be noted that the second screw rod 18 is a bidirectional threaded rod.

[0048] One end of the second screw rod 18 is rotatably mounted on the inner wall of the first groove 22. The other end of the second screw rod 18 extends into the interior of the second groove 10. A third gear 17 is fixedly mounted on one end of the second screw rod 18 located inside the second groove 10;

[0049] A third rack 16 is fixedly mounted on the inner wall of the surveying and mapping box body 1 at a position corresponding to the third gear 17. The third rack 16 is meshedly connected with the third gear 17.

[0050] Furthermore, sliders 20 are slidably mounted on both sides of the interior of the first groove 22. Both sliders 20 are threadedly connected to the second screw rod 18. Both sliders 20 are threadedly connected to the reverse threaded sections on both sides of the second screw rod 18, respectively. Slide rods 19 are slidably inserted on both sides of the opposite surfaces of the two sliders 20. Clamps 21 are fixedly mounted on the ends of the two corresponding slide rods 19 away from the sliders 20. Two springs 23 are fixedly mounted on the opposite back surfaces of the two clamps 21, and the ends of the four springs 23 away from the clamps 21 are fixedly mounted on the corresponding sliders 20, and the four springs 23 are respectively sleeved on the outer sides of the corresponding slide rods 19. The measuring instrument 11 is placed on the upper surface of the support plate 15, and the two clamps 21 are clamped on both sides of the measuring instrument 11.

[0051] Working principle of embodiment 2: The difference between this working principle and the working principle of embodiment 1 is that:

[0052] When in use, the support plate 15 moves up, driving the third gear 17 to move up synchronously. Since the third gear 17 is meshed with the third rack 16, the third gear 17 rotates to drive the second screw rod 18 to rotate. The second screw rod 18 rotates to drive the two sliders 20 to move away from each other along the axis of the second screw rod 18. The two sliders 20 move away from each other, causing the corresponding springs 23 to extend, and then the four springs 23 pull the corresponding clamps 21, so that the two clamps 21 are away from the outer wall of the measuring instrument 11. By arranging the springs 23, when the surveying and mapping box body 1 is bumped or collided during the transfer process, the buffering effect of the springs 23 is used to avoid hard collision of the measuring instrument, thereby avoiding damage to the measuring instrument 11 caused by external force factors, and facilitating the replacement and movement of the measuring instrument 11.

[0053] The other processes are the same as those in the first embodiment and will not be described in detail in this working principle.

[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
