[0001] The invention relates to a geographical measuring ruler, in particular to a multifunctional measuring ruler for geographical surveying and applied in the technical field of measuring rulers. Background Art

[0002] During the geographical survey, surveyors need to carry various measuring rulers with them to collect data and measure the geographical features in order to draw geological survey maps.

[0003] The specification of Chinese patent CN202322041735.6 discloses "A measuring ruler for outdoor use", which is used by pushing the guard plate downward, compressing the spring, and exposing the scale plate. When the pressure on the guard plate is lost, the guard plate moves upward and resets under the action of the spring, thereby shielding and protecting the scale plate. Moreover, a gap is formed between the guard plate and the scale plate, so that the guard plate will not cause friction to the surface of the scale plate when moving up and down, thereby improving the protection of the scale plate.

[0004] The existing measuring ruler and the measuring ruler of the above invention are mostly a long strip of board with measuring scales drawn on the board. When the measuring ruler is used outdoors, the scales on the ruler are easily worn due to friction, which affects the measuring accuracy of the measuring ruler and is not conducive to carrying the measuring ruler in the field. In addition, the traditional measuring ruler needs to be handheld by the staff and set up at the measuring position. However, the field environment is complex and the surveyors cannot reach the designated measuring position, such as the coastal mudflat position, which affects the environmental adaptability of the measuring ruler.

[0033] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1-3The figure shows a multifunctional measuring ruler for geographical survey, comprising a measuring rod 1, wherein the measuring rod 1 is made of a plurality of pipe fittings connected in sequence, and the measuring rod 1 is made of a carbon fiber material, which is convenient for telescopic adjustment of the measuring rod 1, and effectively improves the adaptability range of the measuring ruler. The measuring rod 1 made of the carbon fiber material has a light overall weight, which is convenient for hand-held operation of the measuring rod 1. An operating handle 101 is fixedly connected to the bottom end of the measuring rod 1, and a winding wheel 102 is rotatably connected to the middle part of the operating handle 101. A measuring line 103 is wound inside the winding wheel 102, and the measuring line 103 extends through the measuring rod 1, and a positioning anchor rod is fixedly connected to the extended end of the measuring line 103. 2. A line marker 104 is fixedly connected between the operating handle 101 and the reel 102 (the line marker is a prior art, used to record the length of the line released, and is widely used in the length measurement of the fishing line. Those skilled in the art can fully select a line marker of a suitable model according to actual needs). The line marker 104 corresponds to the measuring line 103. The line marker 104 also includes a zeroing function, which is convenient for zeroing the length data of the measuring line 103. The top end of the measuring rod 1 is rotatably connected to a rod end sleeve 201, and the top end of the positioning anchor rod 2 is sleeved with the rod end sleeve 201. One end of the rod end sleeve 201 is rotatably connected to a vertical angle sensor 202;

[0036] When measuring the length of a geographic survey, a worker holds the measuring rod 1 through the operating handle 101, presses and inserts the positioning anchor rod 2 to the specified position first, especially for use in a tidal flat environment, and then swings the top of the measuring rod 1 to the measuring position, and the winding wheel 102 releases the measuring line 103. The line recorder 104 is used to record the released length of the measuring line 103, and the length data of the two points is easily obtained. The vertical orientation angle of the measuring line 103 is obtained through the vertical angle sensor 202, and the horizontal straight line distance between the two points is obtained by calculating the trigonometric function of the obtained straight line length data. This is convenient for workers to perform geographic survey measurements at locations that cannot be reached, adapts to various complex geographical environments, and effectively improves the accuracy of geographic survey data. During the measurement process, there is no need to judge the length by a scale. Compared with traditional measuring rulers, the environmental adaptability of the measuring ruler is effectively improved.

[0037] Figure 4-7As shown, the internal rotation of the positioning anchor rod 2 is connected with a movable shaft 203, and the two ends of the bottom of the movable shaft 203 are fixedly connected with telescopic teeth 3. Both ends of the bottom of the positioning anchor rod 2 are provided with telescopic holes 204, and the telescopic teeth 3 are correspondingly plugged into the telescopic holes 204. The top of the positioning anchor rod 2 is provided with an extrusion ring 205, and the bottom end of the rod end sleeve 201 corresponds to the extrusion ring 205. The inner ring of the extrusion ring 205 is fixedly connected to the top of the movable shaft 204. The middle part of the positioning anchor rod 2 is fixedly connected with a fixing ring 206, and the fixing ring 206 and the extrusion ring 205 are connected. The sleeve is provided with a spring 207, the telescopic teeth 3 are bent in an arc shape, and the telescopic teeth 3 are made of spring steel material, so that the telescopic teeth 3 can extend out of the telescopic hole 204 during the rising process, thereby improving the stability of the positioning anchor rod 2. The telescopic teeth 3 include upper teeth 301 and lower teeth 302. The bending angle of the upper teeth 301 is greater than the bending angle of the lower teeth 302. The top of the lower teeth 302 is in contact with the middle of the upper teeth 301. The upper teeth 301 and the lower teeth 302 are extended and combined, which effectively improves the structural stability of the telescopic teeth 3 and facilitates the telescopic teeth 3 to withstand greater tension.

[0038] When the positioning anchor rod 2 is inserted and fixed, the top end of the positioning anchor rod 2 is sleeved on the rod end sleeve 201, so that the positioning anchor rod 2 and the measuring rod 1 are combined into an L-shaped hoe state. The staff swings the measuring rod 1 to insert the positioning anchor rod 2 deeply into the specified position, which is particularly suitable for use in the muddy mudflat environment. After the positioning anchor rod 2 is inserted and fixed, the winding wheel 102 releases the measuring line 103, and the rod end sleeve 201 at the top of the measuring rod 1 is separated from the positioning anchor rod 2. The movable shaft 203 rises under the thrust of the spring 207, so that the telescopic teeth 3 extend out of the telescopic holes 204, and the upper teeth 301 and the lower teeth 302 extend out and combine together. The top end of the lower teeth 302 contacts the middle part of the upper teeth 301 to form a triangular support structure, which effectively improves the structural stability of the telescopic teeth 3 and facilitates the telescopic teeth 3 to withstand greater tension, thereby effectively improving the tensile stability of the positioning anchor rod 2 and effectively improving the reliability of the measuring ruler.

[0039] The second implementation method:

[0040] Compared with the first embodiment, this embodiment mainly adds a leveling rod 4. The specific newly added structure is as follows, and the remaining structures are consistent with the first embodiment.

[0041] Figure 8-9As shown, a leveling rod 4 is provided between the rod end sleeve 201 and the positioning anchor rod 2, a sleeve link 401 is fixedly connected to the back of the leveling rod 4, and the sleeve link 401 is sleeved with the measuring line 103, so as to realize setting up the leveling rod 4 at the position of the positioning anchor rod 2, which is convenient for leveling observation of geographical survey, and the sleeve link 401 is arranged in a spiral shape, and the sleeve link 401 is made of spring steel material, which is convenient for the measuring line 103 to be wound into and out of the sleeve link 401, thereby facilitating the disassembly of the leveling rod 4, and the cross section of the leveling rod 4 is arranged in an arc shape, and the scale of the leveling rod 4 is drawn on the outer surface of the arc, and the leveling rod 4 is made of aluminum alloy material, which effectively improves the observation angle of the leveling rod 4, and is convenient for the wide-angle observation of the leveling rod 4;

[0042] When constructing the leveling rod 4, the leveling rod 4 is arranged between the rod end sleeve 201 and the positioning anchor rod 2. Compared with the first implementation mode, the leveling rod 4 increases the length of the positioning anchor rod 2 without destroying the L-shaped hoe state of the positioning anchor rod 2 and the measuring rod 1. The positioning anchor rod 2 is swung and inserted in the same way, and the leveling rod 4 is fixed at the same time, which facilitates the long-distance observation of the leveling rod 4 and effectively improves the efficiency of geographical survey.

[0043] Figure 10-12 As shown, the outer part of the rod end sleeve 201 is rotatably connected with an adjustment ring 402, and the lower surface of the adjustment ring 402 and the upper surface of the extrusion ring 205 are both provided with directional holes 403. The top and bottom ends of the leveling rod 4 are fixedly connected with a plug-in shaft 404, and the plug-in shaft 404 is plugged into the directional hole 403. By rotating and adjusting the adjustment ring 402, the top of the leveling rod 4 is restricted, and the orientation angle of the leveling rod 4 is changed, which is convenient for observing the leveling rod 4 at a suitable position. The outer thread of the adjustment ring 402 is connected with a tightening bolt 405, which is tightened The tightening bolt 405 is in contact with the rod end sleeve 201, and the nut end of the tightening bolt 405 corresponds to the same plane as the directional hole 403. By tightening the tightening bolt 405, the angle of the adjustment ring 402 is easily fixed, which effectively improves the angle adjustment stability of the leveling rod 4. A mounting hole 406 is provided inside the nut end of the tightening bolt 405, and an observation laser light 407 is fixedly inserted inside the mounting hole 406. The laser light extended by the laser light 407 can be observed by observing the inside of the mounting hole 406, which is convenient for setting up the leveling rod 4 in a dim environment.

[0044] When arranging the leveling rod 4 between the rod end sleeve 201 and the positioning anchor rod 2, first rotate and adjust the adjustment ring 402, and use the tightening bolt 405 to tighten and fix the adjustment ring 402. The plug-in shafts 404 at the top and bottom ends of the leveling rod 4 are respectively inserted into the directional holes 403 on the adjustment ring 402 and the extrusion ring 205 to limit the orientation angle of the leveling rod 4. After the positioning anchor rod 2 is installed and fixed, the angle limit of the leveling rod 4 is limited by the extrusion ring 205 on the positioning anchor rod 2. The staff can lift the measuring rod 1 so that the rod end sleeve 201 is separated from the positioning anchor rod 2 as in the first embodiment, which is convenient for the staff to remotely observe the leveling rod 4 at a specified angle and tighten the measuring line 103 at the same time, effectively preventing the plug-in shaft 404 from being separated from the directional hole 403, thereby effectively improving the assembly stability of the leveling rod 4.

[0045] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
