Specific implementation method:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-6 In the present embodiment, a surveying and mapping fixed-point device includes a column 1 and a base plate 4. The bottom of the column 1 is fixedly connected to the top of the base plate 4. The inner wall of the column 1 is connected to a lifting structure 2. The top of the lifting structure 2 is movably connected to a ball column 5. The top of the ball column 5 is fixedly connected to a top plate 6. The top of the top plate 6 is fixedly connected to a groove plate 7. The inner wall of the groove plate 7 can be connected to an external reflector. The right side of the bottom of the top plate 6 is connected to a control structure 3. The right side of the top of the top plate 6 is fixedly connected to a level bubble 8. The model of the level bubble 8 is selected according to usage requirements.

[0024] The lifting structure 2 includes a first screw rod 201 and a sleeve 202. The outer wall of the first screw rod 201 is threadedly connected to the inner wall of the column 1. The upper part of the outer wall of the first screw rod 201 is fixedly connected to the inner wall of the sleeve 202. The sleeve 202 is a rubber sleeve. A disc 203 is fixedly connected to the top of the first screw rod 201. A vertical rod 204 is fixedly connected to the right side of the bottom of the disc 203. The outer wall gap of the vertical rod 204 matches the curved plate 205. The vertical rod 204 is forced to move up and down through the inner wall of the curved plate 205. The left side of the curved plate 205 is fixedly connected to the right top of the column 1. A circular groove is processed on the outer side of the top of the disc 203. The top of the disc 203 is movably connected to the bottom of the outer wall of the ball column 5. The ball column 5 is forced to rotate at multiple angles through the notch on the top of the disc 203.

[0025] By holding the sleeve 202 in the lifting structure 2 and rotating it upward, the rotating sleeve 202 causes the first screw 201 to move upward on the inner wall of the column 1, and the moving first screw 201 moves the disc 203 upward. When the disc 203 moves upward, the vertical rod 204 moves upward on the inner wall of the curved plate 205. The vertical rod 204 cooperates with the curved plate 205 to limit the disc 203, preventing the disc 203 from rotating with the first screw 201, thereby reducing the operating difficulty of the surveying and mapping fixed-point device and ensuring the working efficiency of the surveying and mapping fixed-point device.

[0026] The control structure 3 includes a second screw 301 and a cylinder 302. The upper part of the outer wall of the second screw 301 is rotatably connected to the bottom right side of the top plate 6. The second screw 301 is rotated by the pin on the inner side of the convex plate at the bottom of the top plate 6. At the same time, the pin connected to the second screw 301 can slide on the inner wall of the convex plate, so as to avoid the restriction that the second screw 301 can only move vertically when the top plate 6 rotates. The outer wall of the second screw 301 is threadedly connected to the inner wall of the cylinder 302. The lower part of the outer wall of the cylinder 302 is threadedly connected with a ring 303. The ring 303 is rotated up and down by the outer wall of the cylinder 302 under force. The bottom of the outer wall of the cylinder 302 is plugged into the top circular groove of the disk 203.

[0027] Working principle:

[0028] Installation of survey and mapping fixed-point device:

[0029] Make the bottom of the bottom plate 4 fit with the ground, and then check the position of the level bubble 8. At this time, rotate the cylinder 302 in the top circular groove of the disk 203, adjust the cylinder 302 and the second screw 301 to a position where they can be raised and lowered, and then rotate the cylinder 302 to move the second screw 301 upward. The moved second screw 301 moves upward, and at the same time, the top plate 6 moves upward, and the control of the cylinder 5 at the bottom of the top plate 6 will make the top plate 6 rotate and adjust the angle at the center position to check whether the level bubble 8 is in the center. Then, the ring 303 rotates downward on the outer wall of the cylinder 302, so that the bottom of the ring 303 is pressed against the top of the disk 203, and then the reflector is inserted into the groove plate 7.

[0030] Lifting and adjustment of survey and mapping fixed-point device:

[0031] Hold the sleeve 202 and rotate it upward. Rotating the sleeve 202 causes the first screw 201 to move upward on the inner wall of the column 1. The moving first screw 201 moves the disc 203 upward. When the disc 203 moves upward, the vertical rod 204 moves upward on the inner wall of the curved plate 205. The vertical rod 204 cooperates with the curved plate 205 to limit the disc 203, preventing the disc 203 from rotating with the first screw 201.

[0032] Embodiment 2:

[0033] See also Figure 1-6 : In this embodiment, a surveying and mapping fixed-point device also includes pins 9, and the outer walls of multiple pins 9 are respectively plugged into the top of the base plate 4.

[0034] Working principle:

[0035] When the surveying and mapping fixed-point device is connected to the ground, the bottom plate 4 is brought into contact with the ground, and then the pins 9 pass through the bottom plate 4 from top to bottom and are plugged into the ground, thereby completing the positioning and reinforcement of the bottom plate 4 .

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
