[0002] Land survey is an important foundation for land management work. It is based on cadastral survey and uses surveying technology to accurately measure the location and size of various types of land, boundaries, coordinates of ownership boundary points, plot area and cadastral map to meet the needs of land management departments and other national economic construction departments. During surveying, the surveyor is usually supported by a tripod as a surveying bracket.

[0003] A portable survey support for land space planning is disclosed in a Chinese utility model patent with announcement number CN217208768U, including a mounting platform, a tripod is provided at the bottom of the mounting platform, a supporting platform is provided on the top of the mounting platform, a survey support is provided on the top of the supporting platform, a debugging mechanism is provided inside the supporting platform, the survey support is connected to the debugging mechanism, a survey port is provided on one side of the survey support, a survey device is provided inside the survey support, a heat dissipation mechanism is provided on the survey support, and a protective mechanism is provided inside the survey port of the survey support.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device supports the mounting platform through three telescopic brackets. During the installation of the telescopic brackets, the staff needs to adjust the length of the telescopic brackets in sequence and keep the length of the telescopic brackets stable through the locking bolts set on the telescopic brackets. During this process, the staff needs to turn the locking bolts many times, which is complicated to operate and is not conducive to improving the staff's user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a portable survey bracket for national land space planning.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a portable survey bracket for land space planning, comprising a mounting platform, a support platform arranged on the upper surface of the mounting platform, and a surveying device arranged on the support platform, three support rods are rotatably arranged on the bottom surface of the mounting platform, a slide groove is provided on the bottom surface of the support rod, a slide rod is slidably arranged in the slide groove, the bottom surface of the slide rod is provided with fixed bevel teeth for improving the stability of the slide rod, and a limit assembly for limiting the slide rod is provided on the support rod.

[0007] By adopting the above technical solution, when the staff needs to explore the target area, the staff needs to move the mounting platform to the target area and connect the fixed bevel gear to the ground. Then, the staff needs to adjust the height of the support rod. At this time, the staff only needs to close the limit assembly to move the exploration device to the lowest point under the action of gravity. Furthermore, the staff needs to reopen the limit assembly and pull the mounting platform upwards, so that the three support rods can move upward synchronously, and the slide rod can support the support rod when the staff releases the support rod, thereby reducing the difficulty of operation for the staff.

[0008] Furthermore, a limiting groove is opened on the inner wall of the slide groove, and the limiting assembly includes a limiting plate slidably set in the limiting groove, a plurality of first limiting blocks evenly distributed on the limiting plate near the side wall of the slide rod, and a second limiting block fixed on the slide rod near the side wall of the limiting groove.

[0009] Furthermore, a first inclined surface is provided on the edge where the side wall of the first limit block away from the limit plate intersects with its upper surface, and a second inclined surface is provided on the edge where the side wall of the second limit block close to the limit plate intersects with its bottom surface.

[0010] Furthermore, a return spring is fixed on the side wall of the limit plate away from the first limit block, and the other end of the return spring is fixed on the inner wall of the limit groove away from the slide rod.

[0011] By adopting the above technical solution, when the staff connects the fixed bevel gear with the ground and moves the limit plate in the direction away from the second limit block, the exploration device automatically moves to the lowest point under the action of gravity. Furthermore, the staff needs to loosen the limit plate to automatically reset the limit plate. At this time, the staff only needs to pull the mounting table upward to make multiple first limit blocks pass over the second limit block, thereby making the three support rods move upward synchronously. Subsequently, when the staff loosens the mounting table, the second limit block supports the adjacent first limit block, so that the mounting table remains stable, thereby reducing the difficulty of operation for the staff.

[0012] Furthermore, a connecting rope is fixed on the side wall of the limiting plate away from the sliding rod, and the other end of the connecting rope extends to the outside of the supporting rod and is slidably connected.

[0013] By adopting the above technical solution, when the staff needs to move the limit plate away from the second limit block, the staff only needs to pull the connecting rope to make the limit plate move with the connecting rope, thereby reducing the operating difficulty of the staff.

[0014] Furthermore, a placement groove is provided on the side wall of the support rod, a rotating rod is rotatably provided on the inner wall of the placement groove, a seesaw is fixed on the rotating rod, and the other end of the connecting rope is fixed to the upper end of the seesaw.

[0015] By adopting the above technical solution, when the staff needs to pull the connecting rope, the staff only needs to press the lower end of the seesaw to make the lower end of the seesaw rotate around the rotating rod, and then the connecting rope moves with the upper end of the seesaw, thereby reducing the operating difficulty of the staff.

[0016] Furthermore, a magnet block is arranged at the lower end of the seesaw, and an iron sheet is embedded on the inner wall of the placement groove.

[0017] By adopting the above technical solution, when the staff presses the lower end of the seesaw, the magnet block and the iron sheet are attracted to each other, thereby keeping the seesaw stable. The staff does not need to press the seesaw continuously, thereby reducing the difficulty of operation for the staff.

[0018] Furthermore, the connecting rope is made of nylon.

[0019] By adopting the above technical solution, polyamide, commonly known as nylon, is a general term for thermoplastic resins containing repeating amide groups — [NHCO] — on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its name is determined by the specific number of carbon atoms in the synthetic monomer. Nylon has good wear resistance, and the connecting rope made of nylon has good wear resistance, which is conducive to extending the service life of the connecting rope.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to explore the target area, the staff needs to move the mounting platform to the target area and connect the fixed bevel gear to the ground. Then, the staff needs to adjust the height of the support rod. At this time, the staff only needs to close the limit assembly to move the exploration device to the lowest point under the action of gravity. Furthermore, the staff needs to reopen the limit assembly and pull the mounting platform upwards to move the three support rods upward synchronously, and enable the slide rod to support the support rod when the staff releases the support rod, thereby reducing the difficulty of operation for the staff;

[0022] 2. In the present application, when the staff connects the fixed bevel gear with the ground and moves the limit plate in the direction away from the second limit block, the exploration device automatically moves to the lowest point under the action of gravity.

At this time, the staff only needs to pull the mounting table upward to make multiple first limit blocks pass over the second limit block, thereby making the three support rods move upward synchronously. Subsequently, when the staff loosens the mounting table, the second limit block supports the adjacent first limit block, so that the mounting table remains stable, thereby reducing the difficulty of operation for the staff;

[0023] 3. In the present application, when the staff needs to move the limit plate away from the second limit block, the staff only needs to pull the connecting rope to make the limit plate move along with the connecting rope, thereby reducing the difficulty of operation for the staff.

[0032] A limiting groove 41 is provided on the inner wall of the slide groove 3. The limiting assembly 5 is arranged on the support rod 21 and is used to limit the slide rod 31. The limiting assembly 5 includes a limiting plate 51, a first limiting block 52 and a second limiting block 53. The limiting plate 51 is a rectangular plate-shaped structure, and the limiting plate 51 is slidably arranged in the limiting groove 41. The first limiting block 52 is a rectangular block-shaped structure. A plurality of first limiting blocks 52 are provided and evenly spaced on the side wall of the limiting plate 51 close to the slide rod 31, and a first inclined surface 6 is provided on the edge where the side wall of the first limiting block 52 away from the limiting plate 51 intersects with its upper surface. The second limiting block 53 is a rectangular block-shaped structure. The second limiting block 53 is fixed on the side wall of the slide rod 31 close to the limiting groove 41, and a second inclined surface 61 is provided on the edge where the side wall of the second limiting block 53 close to the limiting plate 51 intersects with its bottom surface. One end of the return spring 7 is fixed to the side wall of the limit plate 51 away from the first limit block 52 , and the other end of the return spring 7 is fixed to the inner wall of the limit slot 41 away from the slide rod 31 .

[0033] When the staff connects the fixed bevel gear 4 with the ground and moves the limit plate 51 away from the second limit block 53, the exploration device automatically moves to the lowest point under the action of gravity. Further, the staff needs to loosen the limit plate 51 to automatically reset the limit plate 51. At this time, the staff only needs to pull the mounting platform 1 upward to make the multiple first limit blocks 52 pass over the second limit block 53, thereby making the three support rods 21 move upward synchronously.

The iron sheet 9 is a sheet structure, and the iron sheet 9 is embedded in the inner wall of the placement groove 8. When the staff presses the lower end of the seesaw 82, the magnet block 83 and the iron sheet 9 are attracted to each other, so that the seesaw 82 remains stable, and the staff does not need to continuously press the seesaw 82, thereby reducing the difficulty of operation for the staff.

[0037] In order to extend the service life of the connecting rope 71, the connecting rope 71 is made of nylon. Polyamide, commonly known as nylon, is a general term for thermoplastic resins containing repeating amide groups - [NHCO] - on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms in the synthetic monomer. Nylon has good wear resistance, and the connecting rope 71 made of nylon has good wear resistance, which is conducive to extending the service life of the connecting rope 71.

[0038] The use principle of a portable survey bracket for land space planning in this embodiment is as follows: when the staff needs to explore the target area, the staff needs to move the mounting platform 1 to the target area and connect the fixed bevel gear 4 to the ground.
