Description

Technical Field

[0001] This utility model relates to the field of land and resources surveying and mapping technology, and more specifically, to a land surveying device. Background Technology

[0002] In land and resources surveying, accurate land information measurement is crucial for land planning and resource management. Land surveying includes cadastral surveying, topographic surveying, land use status measurement, land flatness measurement, and investigation of reserve land resources such as barren hills and wastelands. When surveying land and resources, land surveying equipment is used, typically a ruler and tape measure to measure the area of ​​a specific section of land.

[0003] Based on the above, current land surveying devices typically involve inserting the measuring tape into the ground, and then the surveyor moves the tape by pulling it with a pole. However, this method has been found that during movement, the surveyor is prone to pulling on the end of the tape inserted into the ground, causing it to tip over or tilt, which in turn affects the progress of the surveying work. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure relates to a land surveying device that solves the issue of existing land surveying devices easily tilting or leaning due to the pull of the measuring rod. By setting up a stable structure, it effectively avoids the problem of the device tilting at the end inserted in the soil due to the surveyor holding the measuring rod and pulling the measuring rod, thus preventing measurement errors caused by tilting. This eliminates common factors that cause measurement deviations at their source, ensuring the reliability of measurement data. At the same time, it makes the measurement process smoother, reduces repetitive operations caused by equipment instability, and greatly improves work efficiency.

[0040] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0041] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0042] This utility model provides a land surveying device, including a stable base plate 1 and a stable structure 3;

[0043] A support pole 101 is fixedly connected to the top of the stable base plate 1. A stabilizing structure 3 is provided on the outer side of the support pole 101. The stabilizing structure 3 includes:

[0044] Assembly corner block 301: It is located on the outside of the support column 101, and there are three sets of it. The opposite end of the assembly corner block 301 is provided with a mating screw hole 3011, and an assembly bolt 3012 is installed in the mating screw hole 3011.

[0045] The bottom block 302 is fixedly connected to the bottom of the assembly corner block 301. The inner side wall of the bottom block 302 is provided with a connecting groove 3021. The outer side of the support rod 101 is fixedly connected with a connecting ring 3022, which is located inside the connecting groove 3021.

[0046] The hinge frame 303 is fixedly connected to the bottom of the assembly corner block 301. The hinge frame 303 is hinged to the hinge ear 3032 by the shaft pin 3031. The bottom of the hinge ear 3032 is fixedly connected to the connecting top block 3033. The connecting top block 3033 is fixedly connected to the connecting bottom block 3035 by the connecting slide rod 3034.

[0047] A connecting sleeve 305 is slidably installed on the outside of the connecting slide rod 3034. A stabilizing support rod 3051 is fixedly connected to the middle of the connecting sleeve 305. A locking hole 3052 is provided on the stabilizing support rod 3051. A foot pedal 3053 is fixedly connected to the stabilizing support rod 3051.

[0048] A connecting support cylinder 304 is fixedly connected to the connecting base block 3035. A sliding support hole 3041 is provided inside the connecting support cylinder 304. A locking rod 3042 is slidably installed inside the sliding support hole 3041. A compression protrusion ring 3043 is fixedly connected to the outside of the locking rod 3042.

[0049] The connecting support cylinder 304 has a reset cavity 3044 inside. The inner side wall of the reset cavity 3044 fits against the outer side wall of the extrusion ring 3043. The reset cavity 3044 is provided with a spring 3045. One end of the locking rod 3042 is fixedly connected to a pull handle 3046, and the other end of the locking rod 3042 is inserted into the locking hole 3052.

[0050] By placing the stable base plate 1 on a point to be measured, and then unfolding the stable support rod 3051 through the hinge lug 3032, and then pulling the handle 3046 to drive the locking rod 3042 out of the locking hole 3052, so that it drives the stable support rod 3051 through the foot pedal 3053 to pull out the connecting sleeve 305, so that it forms a triangular shape to provide stable support for the support rod 101. After adjusting, release the handle 3046, because when the locking rod 3042 moves, it squeezes the convex ring 3. 043 compresses the spring 3045 in the reset cavity 3044, causing the spring 3045 to undergo elastic deformation. When the pressure is lost, the spring 3045 pushes the compression protrusion 3043 to move. The compression protrusion 3043 drives the locking rod 3042 to reset and be inserted into the locking hole 3052. Because there are multiple sets of locking holes 3052, the length of each set of stabilizing support rods 3051 can be adjusted according to the terrain. In places with high terrain, the stabilizing support rods 3051 can be shortened.

[0051] Example 2: Based on Example 1, wherein, as Figure 2 and Figure 3 As shown, a connecting column 102 is fixedly connected to the top of the supporting column 101, and a fastening screw 1021 is fixedly connected to the top of the connecting column 102. A measuring structure 2 is provided on the outside of the fastening screw 1021. The measuring structure 2 includes a measuring disc 201 and a rotating shaft column 2011. The measuring disc 201 is provided on the outside of the fastening screw 1021, and the rotating shaft column 2011 is provided in the middle of the measuring disc 201.

[0052] A connecting handle 2012 is fixedly connected to the rotating shaft 2011, and a rotating handle 2013 is fixedly connected to the other end of the connecting handle 2012. A through hole 2014 is opened on the rotating shaft 2011, and a fastening screw 1021 extends through the rotating shaft 2011 to engage with the nut 103.

[0053] A measuring scale 2015 is provided on the outer side of the rotating shaft column 2011, and a measuring rod 202 is provided at one end of the measuring scale 2015.

[0054] By holding the measuring rod 202 and pulling the measuring scale 2015, the measuring rod 202 is inserted into another point on the ground. Then, the nut 103 is turned to press the rotating shaft 2011 to prevent the rotating shaft 2011 from rotating. Finally, the distance between the points can be known by reading the data on the measuring scale 2015. After the measurement is completed, the pressing of the rotating shaft 2011 is released by turning the nut 103. Then, one person holds the measuring rod 202 and walks close to the support pole 101, while another person turns the handle 2013 to make the measuring scale 2015 roll up through the rotating shaft 2011.

[0055] The specific usage and function of this embodiment are as follows:

[0056] In this invention, the stabilizing base plate 1 is placed on a point to be measured. The stabilizing support rod 3051 is then unfolded via the hinge ear 3032. Pulling the handle 3046 causes the locking rod 3042 to disengage from the locking hole 3052. This allows the foot pedal 3053 to pull out the connecting sleeve 305, forming a triangular shape to provide stable support for the support rod 101. After adjustment, the handle 3046 is released. As the locking rod 3042 moves, it compresses the spring 3045 within the reset cavity 3044 via the compression ring 3043, causing the spring 3045 to elastically deform. When the pressure is released, the spring 3045 pushes the compression ring 3043, which in turn moves the locking rod 3042 back into the locking hole 3052, thus reinforcing the support rod 101 and effectively preventing... Because the surveyor held the measuring rod and pulled the measuring tape, the device tilted at one end when inserted into the ground. To prevent measurement errors caused by tilting, this common factor causing measurement deviation was eliminated at its source, ensuring the reliability of the measurement data. Then, the measuring rod 202 was pulled by hand to move the measuring tape 2015, so that the measuring rod 202 was inserted into another point on the ground. Then, the nut 103 was turned to press the rotating shaft 2011 to prevent the rotating shaft 2011 from rotating. Finally, the distance between the points can be known by reading the data on the measuring tape 2015. After the measurement is completed, the pressing of the rotating shaft 2011 is released by turning the nut 103. Then, one person held the measuring rod 202 and walked close to the support pole 101, while another person turned the handle 2013 to make the measuring tape 2015 roll up through the rotating shaft 2011.
