DETAILED DESCRIPTION

[0031] The following is a combination of specific implementation cases and attached Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0032] See Figures 1 to 5 As shown, a topographic surveying pole includes a pole body, which includes a plurality of first pole bodies 1 and a plurality of second pole bodies 2. The first pole body 1 is arranged above the second pole body 2, wherein a tip portion 3 is installed below the bottom end of the second pole body 2; the first pole body 1 and the second pole body 2 are detachably connected by a connecting assembly; Figure 5 As shown, the connecting assembly includes a bolt 26 fixedly installed at the bottom end of the first rod body 1, and also includes a threaded groove 27 opened on the top of the second rod body 2. The thread of the bolt 26 is embedded in the inner cavity of the threaded groove 27. When the benchmark is stored after use, the first rod body 1 can be rotated and adjusted relative to the second rod body 2 to cause the bolt 26 at the bottom end of the first rod body 1 to disengage from the inner cavity of the threaded groove 27, thereby realizing the separation of the first rod body 1 and the second rod body 2, and then adjusting the entire device to a multi-stage type for easy storage; a top seat 4 is installed at the top of the benchmark body, and a mounting rod 5 is fixed and vertically installed at the middle of the top of the top seat 4. A fixing plate 6 is fixedly installed on the side wall of the mounting rod 5, and a plurality of positioning components are equidistantly arranged on the fixing plate 6 along the circumferential direction. A rotating seat 12 is rotatably provided on the mounting rod 5 through a bearing, and a first indicator plate 13 is fixedly installed on the side wall of the rotating seat 12. A fixed seat 14 is fixedly installed, and a second indicator plate 15 is fixedly installed on the side wall of the fixed seat 14. The rotating seat 12 is arranged below the fixed seat 14; each group of positioning components includes a positioning rod 7 that passes through the fixed disk 6 in the vertical direction, and a positioning seat 8 is installed on the top of the positioning rod 7. The left and right side walls of the positioning seat 8 are respectively provided with inclined ends 9. The bottom end of the positioning seat 8 is sleeved with a spring 10, and the two ends of the spring 10 are respectively connected to the lower surface of the fixed disk 6 and the outer wall of the positioning seat 8; the inclined end 9 is arranged to be inclined downward from the middle of the positioning seat 8 to the edge of the positioning seat 8, so as to ensure that the first indicator plate 13 entering the inner cavity of the positioning seat 8 from the side can move along the inner wall of the inclined end 9, prompting the positioning seat 8 to automatically move downward to compress the spring 10 at the corresponding position, and then ensure that the subsequent positioning seat 8 can automatically move upward to position the first indicator plate 13;

[0033] When the angle of the first indicator plate 13 needs to be adjusted relative to the second indicator plate 15, the positioning rod 7 corresponding to the bottom end of the first indicator plate 13 is pressed downward, causing the positioning seat 8 here to disengage from the limit of the first indicator plate 13, and the first indicator plate 13 is rotated. The first indicator plate 13 will cause the rotating seat 12 to rotate along the mounting rod 5 to adjust the angle of the first indicator plate 13 relative to the second indicator plate 15. When the side wall of the first indicator plate 13 rotates to touch the inclined end 9, the first indicator plate 13 that continues to rotate will cause the inclined end 9 and the positioning seat 8 to move downward. At this time, the positioning seat 8 drives the positioning rod 7 to move downward and causes the spring 10 to be forced to stretch. When the first indicator plate 13 is rotated to be completely embedded in the inner cavity of the positioning seat 8, the elastic force of the spring 10 causes the positioning rod 7 and the positioning seat 8 to move upward, realizing the limiting effect of the positioning seat 8 on the first indicator plate 13, so as to realize the positioning of the first indicator plate 13 after rotation, and ensure that the angle between the first indicator plate 13 and the second indicator plate 15 after the angle adjustment is stable.

[0034] In order to facilitate the downward movement of the positioning rod 7, a pressing piece 11 is installed on the bottom side wall of the positioning rod 7. By pressing the pressing piece 11, the positioning rod 7 can be driven to move downward synchronously, so that the positioning seat 8 can be disengaged from the positioning of the first indicator plate 13 downward.

[0035] Main references Figure 2 As shown, the top end of the mounting rod 5 is rotatably connected to a rotating cylindrical seat 16 through a bearing, an insert block 17 is inserted into the rotating cylindrical seat 16, and a positioning bolt 18 is provided through a thread on the side wall of the rotating cylindrical seat 16, and the free end of the positioning bolt 18 is abutted against the side wall of the insert block 17. By rotating the rotating cylindrical seat 16 circumferentially relative to the mounting rod 5, the direction of the reflector 23 can be adjusted, thereby realizing the use requirements of reflective indication in different directions.

[0036] Main references Figure 2 and Figure 3As shown, the side wall of the plug 17 is provided with a clearance groove 19, and the inner cavity of the clearance groove 19 is provided with a rotating shaft 20 through a bearing, and the front end of the rotating shaft 20 extends out of the side wall of the plug 17, and a connecting block 21 is fixedly installed on the rotating shaft 20, and a placement frame 22 is fixedly installed on the top of the connecting block 21. A reflector 23 is slidably inserted in the placement frame 22. Rotating the rotating shaft 20 causes it to drive the connecting block 21, the placement frame 22 and the reflector 23 to rotate together, thereby realizing the adjustment of the pitch angle of the reflector 23; a positioning pin 25 is provided through the outer wall of the rotating shaft 20, and a plurality of positioning holes 24 are provided on the side wall of the plug 17 along the circumferential direction, and the positioning pin 25 is embedded in the inner cavity of one of the positioning holes 24; wherein, the positioning hole 24 is fixed with the rotating shaft 20 The center of the circle is arranged equidistantly along the circumference of the axis; the indicated direction is marked with the help of the reflection principle of the reflector 23. When the reflection angle of the reflector 23 needs to be adjusted, the positioning pin 25 is pulled out of the corresponding positioning hole 24 to the front side, and the rotating shaft 20 is rotated to drive the connecting block 21, the placement frame 22 and the reflector 23 to rotate together, thereby realizing the adjustment of the pitch angle of the reflector 23. After adjustment, the positioning pin 25 is reinserted into the corresponding positioning hole 24 to realize the positioning of the reflector 23 after the pitch adjustment; in addition, the rotating cylindrical seat 16 is rotated circumferentially relative to the mounting rod 5, so that the direction of the reflector 23 can be adjusted, thereby realizing the use requirements of reflective indication in different directions.

[0037] The working principle of a topographic surveying and mapping pole in this embodiment when in use is as follows:

[0038] When in use, the tip portion 3 is inserted into the ground, and the first rod body 1 and the second rod body 2 are made perpendicular to the ground, and the first indicator plate 13 is rotated relative to the second indicator plate 15 to indicate the synchronous angle; when the angle of the first indicator plate 13 relative to the second indicator plate 15 needs to be adjusted, the corresponding pressing piece 11 at the bottom end of the first indicator plate 13 is pressed downward to cause the positioning seat 8 here to break away from the limit of the first indicator plate 13, and the first indicator plate 13 is rotated. The first indicator plate 13 will cause the rotating seat 12 to rotate along the mounting rod 5 to adjust the angle of the first indicator plate 13 relative to the second indicator plate 15. When the side wall of the first indicator plate 13 is rotated to touch the inclined end 9, The first indicator plate 13 that continues to rotate will cause the inclined end 9 and the positioning seat 8 to move downward. At this time, the positioning seat 8 drives the positioning rod 7 to move downward, and causes the spring 10 to be forced to stretch. When the first indicator plate 13 is rotated to be completely embedded in the inner cavity of the positioning seat 8, the elastic force of the spring 10 causes the positioning rod 7 and the positioning seat 8 to move upward, realizing the limiting effect of the positioning seat 8 on the first indicator plate 13, so as to realize the positioning of the first indicator plate 13 after rotation, and ensure that the angle between the first indicator plate 13 and the second indicator plate 15 is stable after the angle adjustment. The first indicator plate 13 can be flexibly converted and positioned by 90 degrees, 180 degrees and 270 degrees relative to the second indicator plate 15, that is, it can mark the above angles;

[0039] The direction of the indication is marked by means of the reflection principle of the reflector 23. When the reflection angle of the reflector 23 needs to be adjusted, the positioning pin 25 is pulled out of the corresponding positioning hole 24 to the front side, and the rotating shaft 20 is rotated to cause it to drive the connecting block 21, the placement frame 22 and the reflector 23 to rotate together, thereby achieving the adjustment of the pitch angle of the reflector 23. After the adjustment, the positioning pin 25 is reinserted into the corresponding positioning hole 24 to achieve the positioning of the reflector 23 after the pitch adjustment. In addition, the rotating cylindrical seat 16 is rotated circumferentially relative to the mounting rod 5 to adjust the direction of the reflector 23, thereby achieving the use requirements of reflective indication in different directions.

[0040] When the pole is stored after use, the first pole body 1 can be rotated relative to the second pole body 2 to disengage the bolt 26 at the bottom end of the first pole body 1 from the inner cavity of the thread groove 27, thereby separating the first pole body 1 and the second pole body 2, and then adjusting the entire device into a multi-stage type for easy storage;

[0041] The present invention can provide auxiliary indication for the measured angle. Compared with the existing method of relying solely on surveying and mapping benchmarks, it can more quickly and conveniently effectively mark and record the angles in the measurement process, thereby improving the efficiency of surveying and mapping operations and the accuracy of data, and is more conducive to the smooth implementation of complex surveying and mapping tasks and the high-quality presentation of surveying and mapping results. It can also adjust and position the pitch angle of the reflector 23 to achieve precise positioning of the reflector 23 at different heights on the three-dimensional plane, and stably perform accurate indication functions, thereby expanding the adaptability and practicality of the reflector 23 in space application scenarios, and providing more reliable and diversified indication solutions for related operations or observation tasks.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
