In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or embodiments in a suitable manner.

[0021] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0022] An embodiment of the present invention provides a surveying and mapping device for urban and rural road planning, comprising: a rod body 1; a connecting mechanism 2, wherein the connecting mechanism 2 is arranged between adjacent rod bodies 1, and the connecting mechanism 2 has a first locking state and a second locking state. When the connecting mechanism 2 is in the first locking state, a plurality of rod bodies 1 can be connected end to end to form a straight-line benchmark. When the connecting mechanism 2 is in the second locking state, adjacent rod bodies 1 are disconnected from each other in pairs, so that the benchmark forms a continuous broken-line structure.

[0023] Specifically, Figure 1 When the connecting mechanism 2 is in the first locking state, the rod body 1 can be connected end to end to form a straight pole, so that the pole can stand on the ground. Figure 2 When the connecting mechanism 2 is in the second locking state, the pole forms a continuous broken-line structure, allowing the worker to tow it.

[0024] It should be noted that when planning urban and rural roads, field surveying is required in the early stage in the wild environment. The wild environment includes mountainous areas, fields, etc. The surveying environment is harsh, and staff often need to carry benchmarks on foot to multiple predetermined surveying points. Benchmarks are not easy to carry. Even if the benchmarks are designed to be telescopic, foldable, or other structural forms, staff still need to carry them on their backs or in their hands, which is particularly laborious. If the benchmarks are dragged directly, dragging will also be more laborious due to the higher center of gravity when the benchmarks are tilted.

[0025] In this optional embodiment, combined with Figure 1 and Figure 2 As shown, by arranging a connecting mechanism 2 between adjacent rod bodies 1, and the connecting mechanism 2 has two states, a first locking state and a second locking state, when the connecting mechanism 2 is in the first locking state, a plurality of rod bodies 1 can be connected end to end to form a straight-line benchmark, and by setting the benchmark on a surveying point on the ground, the surveying work of the surveying point can be carried out. After the surveying of the surveying point is completed, by putting the connecting mechanism 2 in the second locking state, the adjacent rod bodies 1 are disconnected from each other to form a continuous broken-line structure of the benchmark, thereby lowering the center of gravity. In this way, the staff can drag it labor-savingly, so that the staff can carry it in the field.

[0026] Optionally, the connecting mechanism 2 includes a first sphere 21, a connecting rod 22 and a second sphere 23, the corresponding end faces of each adjacent rod body 1 are provided with a second opening groove 14, the bottom end of the second opening groove 14 is provided with a ball groove 11, the first sphere 21 and the second sphere 23 are respectively arranged in the two ball grooves 11, the first sphere 21 and the second sphere 23 are respectively provided with a first socket 211 and a second socket 231, the two ends of the connecting rod 22 are respectively slidably inserted in the first socket 211 and the second socket 231, and a locking structure is provided in the first socket 211 and the second socket 231, and the locking structure is used to lock the corresponding end of the connecting rod 22 so that the connecting mechanism 2 can switch between the first locking state and the second locking state.

[0027] In this optional embodiment, combined with Figure 1 and Figure 3 As shown, the locking structure puts the connecting mechanism 2 in a first locking state, and the first sphere 21, the connecting rod 22 and the second sphere 23 cannot rotate. At this time, the multiple rods 1 are stably connected end to end. Figure 2 and Figure 4 As shown, two adjacent rod bodies 1 are disconnected from each other, and the first sphere 21 and the second sphere 23 can rotate in the corresponding ball groove 11, so that the connecting rod 22 can move within the range of the second opening groove 14, so that the two adjacent rod bodies 1 can rotate relative to each other. When the staff constantly bypasses obstacles such as trees in the mountains, the rod body 1 held by the staff can drive other rod bodies 1 to turn in the direction of the bypass path, thereby improving the convenience in actual use.

[0028] Furthermore, the locking structure includes a buckle and a slot. The buckle is connected to the inner walls of the first plug hole 211 and the second plug hole 231. Two slots are respectively provided at both ends of the connecting rod 22. The buckle is used to engage with the slots.

[0029] In this optional embodiment, combined with Figure 3 and Figure 4 As shown, the buckle and the slot are not shown in the figure. Two slots are respectively provided at both ends of the connecting rod 22. In other words, each end of the connecting rod 22 is provided with two slots, one in front and one in the back. The buckle is connected to the inner wall of the first plug hole 211 and the second plug hole 231 near the hole opening, as shown in FIG. Figure 3 As shown, the buckle is snapped into the slots near the center at the two ends of the connecting rod 22, and forces in opposite directions are applied to the two adjacent rod bodies 1, so that the two ends of the connecting rod 22 slide in the first plug hole 211 and the second plug hole 231 respectively, until the buckle is snapped into the slots far from the center at the two ends of the connecting rod 22, so as to achieve the following effect. Figure 4 Status shown.

[0030] In other optional embodiments, the buckle can be replaced by other fasteners, and the slot can be a corresponding buckle position to achieve the above-mentioned equivalent effect.

[0031] Furthermore, the surveying and mapping device for urban and rural road planning also includes a positioning mechanism 3, which includes a plurality of soil insertion units, and the plurality of soil insertion units are all arranged at the bottom of the lowest rod body 1.

[0032] In this optional embodiment, combined with Figure 1 and Figure 8 As shown, the stability of the pole is improved by inserting the soil-inserting unit into the soil layer.

[0033] Optionally, the soil insertion unit includes a pin 31, a first spring 33 and a pressure plate 34. The bottom end surface of the rod body 1 is provided with a slot 12, the pin 31 is slidably inserted in the slot 12, one end of the first spring 33 is connected to the top end of the pin 31, the other end of the first spring 33 is connected to a side surface of the pressure plate 34, and the other side surface of the pressure plate 34 is detachably connected to the bottom end surface of the rod body 1.

[0034] In this optional embodiment, combined with Figure 5As shown, it should be noted that the first spring 33 is a spring with high stiffness, high elastic modulus, and high spring constant, which has the characteristics of not easily generating compression deformation when pressure is applied. In other words, it can enable the pin 31 to be normally inserted into the soil layer. When there are obstacles such as tree roots and stones in the soil layer, the corresponding pin 31 is blocked. At this time, pressure continues to be applied, and the remaining pins 31 continue to penetrate into the soil layer, and the blocked pins 31 will squeeze the bottom end of the corresponding first spring 33. At this time, the top of the first spring 33 is also subjected to the downward squeezing force of the pressure plate 34, thereby forcing the first spring 33 to be compressed. In this way, the remaining pins 31 can be normally inserted into the soil layer to avoid affecting the normal surveying and mapping work of the surveying and mapping point. The pressure plate 34 can be detachably connected to the bottom end face of the rod body 1 by magnetic attraction. When towing, the pressure plate 34 is magnetically attracted to the bottom end face of the rod body 1, so that it can position the pin 31 in the slot 12 through the first spring 33.

[0035] Furthermore, the soil insertion unit also includes a pressure rod 32, the bottom end surface of the rod body 1 is provided with a through hole, the bottom circumference of the rod body 1 is provided with a first open groove 13, one end of the pressure rod 32 is connected to the pressure plate 34, and the other end of the pressure rod 32 passes through the through hole into the first open groove 13.

[0036] In this optional embodiment, combined with Figure 5 , Figure 6 and Figure 7 As shown, the pressing rod 32 can guide the pressing plate 34 . In other words, the pressing plate 34 can only move in the vertical direction, thereby preventing the first spring 33 from being laterally offset.

[0037] Optionally, the surveying and mapping device for urban and rural road planning also includes a walking mechanism 4, which includes a first roller 41, a mounting rod 42, a pin 43, a torsion spring 44 and a wheel mounting frame 45. One end of the mounting rod 42 is connected to the bottom of the rod body 1, and the other end of the mounting rod 42 is rotatably connected to one end of the wheel mounting frame 45 through the pin 43. The other end of the wheel mounting frame 45 is rotatably installed with the first roller 41. The torsion spring 44 is sleeved on the pin 43, and the two ends of the torsion spring 44 are respectively connected to the mounting rod 42 and the wheel mounting frame 45.

[0038] In this optional embodiment, when the nail 31 is inserted into the soil layer, the ground will exert a reaction force on the first roller 41, causing the wheel mounting frame 45 to rotate relative to the mounting rod 42, causing the first roller 41 to gradually roll in a direction away from the nail 31. At this time, the torsion spring 44 gradually twists, and the first roller 41 exerts pressure on the ground until multiple first rollers 41 are spread out on the ground, thereby allowing the first roller 41 to play an auxiliary supporting role, further improving the stability of the benchmark, especially in high-altitude mountainous areas with strong winds, and has a strong use effect.

[0039] Furthermore, the walking mechanism 4 also includes an L-shaped rod 47, the first roller 41 includes a rim 411, a wheel disc 412 and a second spring 413, the wheel disc 412 is arranged at the center of the rim 411, the outer circumference of the wheel disc 412 and the inner circumference of the wheel rim 411 are connected by a plurality of second springs 413, the wheel disc 412 is rotatably connected to the corresponding end of the wheel mounting frame 45 through a rotating shaft, one end of the L-shaped rod 47 is connected to the wheel mounting frame 45, and the other end of the L-shaped rod 47 is used to abut against the top end of the pressure rod 32.

[0040] In this optional embodiment, combined with Figure 5 , Figure 6 and Figure 7 As shown, when the pin 31 is inserted into the soil layer, the ground will apply a reaction force to the first roller 41, causing the wheel mounting frame 45 to rotate relative to the mounting rod 42. At this time, the L-shaped rod 47 will apply pressure to the top of the pressure rod 32, causing the pressure rod 32 to move downward, forcing the pressure plate 34 to separate from the bottom end surface of the rod body 1, thereby applying pressure to the pin 31 through the first spring 33, thereby increasing the force of the pin 31 when inserted into the soil layer. For some harder soil layers, it also has a better insertion effect. When a pin 31 encounters an obstacle, the pin 31 cannot continue to move downward, forcing the corresponding pressure rod 32 to be unable to move downward. Since the rod body 1 is still moving downward as a whole, the L-shaped rod 47 applies pressure to the wheel disc 412, and the wheel disc 412 squeezes and moves toward the bottom of the wheel rim 411, and compresses the corresponding second spring 413, so that the L-shaped rod 47 will not have motion interference.

[0041] Furthermore, the walking mechanism 4 further includes a second roller 46 , and the second roller 46 is rotatably connected to the inflection point of the L-shaped rod 47 via a rotating shaft.

[0042] In this optional embodiment, if Figure 2 As shown, during towing, when the bottommost rod body 1 is relatively horizontal, the second roller 46 can roll in contact with the ground, so that the turning point of the L-shaped rod 47 will not contact the ground, thereby improving the towing effect.

[0043] Optionally, the outer circumferential surface of the rim 411 and the outer circumferential surface of the second roller 46 are both covered with rubber rings.

[0044] In this optional embodiment, the friction with the ground is increased by coating the outer circumference of the wheel rim 411 and the outer circumference of the second roller 46 with a rubber ring.

[0045] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
