[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a portable measuring rod for topographic surveying.

[0026] This utility model provides, for example Figure 1-3 A portable measuring rod for topographic surveying is shown, comprising a base rod 1, a middle rod 2, and a top rod 3. A receiver 4 is fixedly mounted on the top of the top rod 3, and a pin 5 is fixedly mounted on the bottom of the base rod 1. The pin 5 is a pointed conical pin. Rotary connecting assemblies are provided between both ends of the middle rod 2 and the base rod 1 and the top rod 3. The rotary connecting assemblies include two symmetrically arranged connecting plates 8. Two symmetrically arranged first connecting rods 9 are fixedly mounted on both ends of the middle rod 2. Two symmetrically arranged second connecting rods 10 are fixedly mounted on the sides of the two adjacent first connecting rods 9 and second connecting rods 10. The connecting plates 8 are rotatably sleeved on the outside of the two adjacent first connecting rods 9 and second connecting rods 10.

[0027] Both ends of the middle rod 2 are provided with grooves, and the positioning rod 6 slides through the grooves. The bottom rod 1 and the top rod 3 are both provided with positioning grooves 7 at their close ends, and the positioning rod 6 is inserted into the positioning groove 7.

[0028] When the measuring rod is needed, it is taken out from its folded state. Since the connecting plate 8 is rotatably sleeved on the outside of the first connecting rod 9 and the second connecting rod 10, it can rotate around the connection point. The middle rod 2 is unfolded relative to the bottom rod 1 and the top rod 3, so that they are in a straight line. At this time, the positioning rods 6 in the grooves at both ends of the middle rod 2 will align with the positioning grooves 7 on the bottom rod 1 and the top rod 3, preparing for subsequent positioning and splicing. The pointed conical pins 5 facilitate insertion into the ground, allowing the measuring rod to stand stably during measurement and ensuring the accuracy of the measurement data.

[0029] To ensure that the positioning rod 6 can be easily pressed into the positioning slot 7, and to guarantee that multiple parts of the measuring rod can be quickly assembled, such as... Figure 1 and Figure 3As shown, both ends of the rod wall of the middle rod 2 are provided with sliding grooves 11. The sliding grooves 11 are connected to the grooves. A pull rod 12 slides through the inside of the sliding groove 11. The pull rod 12 is fixedly connected to the positioning rod 6. A spring 13 is fixed between the pull rod 12 and the inner wall of the sliding groove 11. A guide rod 14 is fixedly provided on the inner wall of the sliding groove 11. The guide rod 14 slides through the inside of the pull rod 12 and passes through the inside of the spring 13.

[0030] When unfolding and assembling the various parts of the measuring rod, press the pull rod 12. The pull rod 12 slides along the guide rod 14 in the slide groove 11, compressing the spring 13. At this time, the positioning rod 6 will retract into the groove along with the pull rod 12. When the bottom rod 1, middle rod 2, and top rod 3 are unfolded to the appropriate position through the rotating connecting assembly, and the positioning rod 6 is aligned with the positioning groove 7, release the pull rod 12. Under the elastic force of the spring 13, the pull rod 12 drives the positioning rod 6 to pop out towards the positioning groove 7 and insert it into the positioning groove 7, thereby firmly splicing the bottom rod 1, middle rod 2, and top rod 3 together, completing the assembly of the measuring rod, which can be immediately put into topographic surveying work.

[0031] In order to stably bind the folded measuring rod and reduce the space occupied by the measuring rod during transportation, such as Figure 1 As shown, a connecting ring 15 is fixedly sleeved on the lower end of the bottom rod 1, and a first hook and loop tape 16 and a second hook and loop tape 17 are fixedly mounted on the outer wall of the connecting ring 15. The first hook and loop tape 16 and the second hook and loop tape 17 are bonded together.

[0032] When the measurement work is finished and the measuring rod needs to be folded up, first press the pull rod 12 to disengage the positioning rod 6 from the positioning groove 7. Then, fold the bottom rod 1, middle rod 2, and top rod 3 by rotating the connecting assembly. After folding, glue the first Velcro strap 16 and the second Velcro strap 17 together to tightly bind the folded measuring rod and prevent the parts from loosening and shaking. In this way, the measuring rod occupies less space and is more convenient to carry and transport. It can be easily put into a measuring tool bag or other carrying equipment, making it easier for the measuring personnel to move to the work site.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
