[0036] Please see Figures 1-8 This utility model provides an embodiment of a surveying and demarcation measuring device, comprising a handle 1 and a central beam 2. The central beam 2 is mounted on the bottom end of the handle 1. A central seat 3 is symmetrically mounted on the outer wall of the central beam 2. A traveling shaft 4 is movably fitted inside each central seat 3. Traveling wheels 5 are fitted on the surface of the traveling shaft 4, and a winding drum 6 is provided between the two sets of traveling wheels 5. A scale rope body 8 is provided on the outer wall of the winding drum 6. A connecting plate 32 is mounted on the bottom end of the central beam 2, and a baffle 7 is mounted on the bottom end of the connecting plate 32. A positioning rod 9 is provided on the outer side of the handle 1 away from the connecting plate 32, and the scale rope body 8 extends to the positioning rod. On the surface of the position rod 9, a top cover 11 is provided between the two sets of traveling wheels 5 above the center beam 2, and the top cover 11 is connected to the center seat 3. An angle dial 10 is installed on the top of the top cover 11, and a pointer 31 is movably installed on the top of the angle dial 10. A laser light 30 is installed on the top of the pointer 31. A ring gear 12 is installed inside each of the traveling wheels 5. A drive shaft 14 is installed at both ends of the winding drum 6.

A planetary gear 13 is fitted on the surface of the drive shaft 14 on one side of the ring gear 12, and the planetary gear 13 meshes with the ring gear 12.

[0037] Positioning rod 9 is placed at the bend in the ground. The ruler rope body 8 is passed through guide tube 25 and support ring 26 and fixed to positioning rod 9. Handle 1 is manually pulled, causing the traveling wheel 5 to rotate. Handle 1 supports center beam 2, which in turn supports center seat 3. Center seat 3 supports traveling wheel 5 via traveling shaft 4. Traveling wheel 5 drives ring gear 12 to rotate around traveling shaft 4. With ring gear 12 meshing with planetary gear 13, ring gear 12 drives planetary gear 13 to rotate. Planetary gear 13 drives transmission shaft 14 to rotate under the support of support arm 15. Transmission shaft 14 drives winding drum 6 to rotate. Supported by positioning rod 9, the rotation of winding drum 6 releases ruler rope body 8. Ruler rope body 8 passes through guide tube 25 and support ring 26 and is led out to the outside. The distance is easily observed by monitoring the release of the scale rope body 8, which facilitates the measurement of the distance between two corners. When it is necessary to measure the angle between two corners, the laser beam emitted by the laser lamp 30 is parallel to the initial boundary. The pointer 31 is moved and adjusted according to the direction of the laser beam emitted by the laser lamp 30 until the laser beam is parallel to the next boundary. The corner angle is obtained by reading the number on the angle dial 10. After completion, the positioning rod 9 is placed at the corner, and then the above steps are repeated until the entire edge is measured. This realizes the convenient manual pushing and moving of the measuring device, which facilitates the recording of the length based on the amount of manual pushing. It also facilitates the stable transmission drive of the mechanical structure, reduces the cost of later damage and maintenance by eliminating the need for electrical components, and improves the convenience and efficiency of the measuring device in surveying and boundary determination.

[0038] A front bevel gear 16 is fitted onto the surface of the drive shaft 14 near the support arm 15. Support frames 22 are installed on the outer walls of both sides of the top cover 11. Connecting arms 19 are installed at the bottom of each support frame 22, and a central connecting shaft 18 is movably installed at the bottom of each connecting arm 19. A central bevel gear 17 is installed at one end of the central connecting shaft 18, meshing with the front bevel gear 16. A rear bevel gear 20 is installed at the other end of the central connecting shaft 18. A reciprocating threaded rod 23 is installed between the two sets of support frames 22, and a first bevel gear 21 is fitted onto the surface of the reciprocating threaded rod 23. The first bevel gear 21 meshes with the rear bevel gear 20. A reciprocating threaded sleeve 29 is fitted on the surface of the reciprocating threaded rod 23. A limit rod 24 is slidably installed inside the reciprocating threaded sleeve 29 near the reciprocating threaded rod 23. Both ends of the limit rod 24 are connected to the support frame 22. A universal shaft 28 is installed at the top of the reciprocating threaded sleeve 29. A universal sleeve 27 is movably installed at the top of the universal shaft 28. A guide tube 25 is installed at the top of the universal sleeve 27. The scale rope body 8 extends to the outside of the guide tube 25. A support ring 26 is installed on the outer wall of the guide tube 25.

[0039] The drive shaft 14 drives the front bevel gear 16 to rotate. Under the meshing of the front bevel gear 16 and the middle bevel gear 17, the front bevel gear 16 drives the middle bevel gear 17 to rotate. Supported by the center seat 3 on the top cover 11, by the top cover 11 on the support frame 22, and by the support frame 22 on the connecting arm 19, the middle bevel gear 17 drives the middle connecting shaft 18 to rotate. The middle connecting shaft 18 drives the rear bevel gear 20 to rotate. The rear bevel gear 20 drives the first bevel gear 21 to rotate. Supported by the support frame 22, the first bevel gear 21 drives the reciprocating threaded rod 23 to rotate. With the reciprocating threaded rod 23 threadedly connected to the reciprocating threaded sleeve 29, the reciprocating threaded rod 23 drives the reciprocating threaded sleeve 29 to reciprocate. The reciprocating threaded sleeve 29 drives the universal joint 28, the universal sleeve 27, and the support ring 26. The guide cylinder 25 and the scale rope body 8 reciprocate. During the release of the scale rope body 8, the guide cylinder 25 rotates due to the movable connection between the universal joint 28 and the universal sleeve 27, facilitating the stable release of the scale rope body 8. This achieves guided release of the scale rope body 8 by the measuring device, preventing the scale rope body 8 from tangling during release or rewinding. It facilitates rapid land surveying and demarcation of different lengths and convenient angle measurement of different corners, improving the ease of use of the measuring device. After the measurement is completed, the handle 1 is manually pulled in the opposite direction, and the traveling wheel 5 drives the winding drum 6 to reverse. The scale rope body 8 is wound around the surface of the winding drum 6, achieving guided release of the scale rope by the measuring device. This facilitates smooth lead-out of the scale rope and avoids tangling.

[0040] In this embodiment, the following steps are taken: First, the positioning rod 9 is placed at the bend in the ground. The ruler rope body 8 is passed through the guide tube 25 and the support ring 26 and fixed to the positioning rod 9. The handle 1 is pulled manually, and the walking wheel 5 rotates under human drive. The handle 1 supports the center beam 2. The walking wheel 5 drives the annular gear ring 12 to rotate around the walking shaft 4. Under the meshing of the annular gear ring 12 and the planetary gear 13, the annular gear ring 12 drives the planetary gear 13 to rotate. The planetary gear 13 drives the transmission shaft 14 to rotate under the support of the support arm 15. The transmission shaft 14 drives the winding... As the cylinder 6 rotates, supported by the positioning rod 9, the rotation of the winding cylinder 6 releases the scale rope body 8. The scale rope body 8 passes through the guide cylinder 25 and the support ring 26 and extends to the outside. The amount of release of the scale rope body 8 is observed manually to facilitate the observation of the distance, which is convenient for measuring the distance between two corners. When it is necessary to measure the angle between two corners, the direction of the laser beam emitted by the laser lamp 30 is parallel to the initial boundary. The pointer 31 is adjusted according to the direction of the laser beam emitted by the laser lamp 30 until the laser beam is parallel to the next boundary. The angle is then read from the angle dial 1. The number on 0 gives the turning angle measurement. After completion, the positioning rod 9 is placed at the corner. Then, the above steps are repeated until the entire edge is measured. The transmission shaft 14 drives the front bevel gear 16 to rotate, the front bevel gear 16 drives the middle bevel gear 17 to rotate, the middle bevel gear 17 drives the middle connecting shaft 18 to rotate, the middle connecting shaft 18 drives the rear bevel gear 20 to rotate, the rear bevel gear 20 drives the first bevel gear 21 to rotate, and under the support of the support frame 22, the first bevel gear 21 drives the reciprocating threaded rod 23 to rotate, and the reciprocating threaded rod 23 drives the reciprocating threaded sleeve 2... 9. The reciprocating threaded sleeve 29 drives the universal joint 28, universal sleeve 27, support ring 26, guide cylinder 25, and scale rope body 8 to reciprocate. During the release of the scale rope body 8, the guide cylinder 25 rotates due to the movable connection between the universal joint 28 and the universal sleeve 27, which facilitates the stable release of the scale rope body 8. This enables the measuring device to guide the release of the scale rope body 8, preventing the scale rope body 8 from getting tangled when released or rewound. This facilitates the rapid surveying and demarcation of land of different lengths, thus completing the use of the measuring device.
