Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping equipment technology, and in particular to a portable surveying and mapping device. Background Technology

[0002] Surveying devices are specialized equipment used to accurately acquire geospatial data. Their technological evolution and industry applications are deeply integrated, making them an indispensable tool in modern engineering construction, urban planning, environmental monitoring and other fields. Surveying devices have evolved from traditional tools into intelligent, multimodal data acquisition and processing platforms. With the deep integration of AI, 5G and IoT technologies, they will play a more critical role in fields such as digital twins and carbon neutrality monitoring.

[0003] In order to make the existing surveying equipment more convenient to carry, casters are usually installed directly on the support legs of the surveying equipment to facilitate its movement. However, when the surveying equipment is in operation, the casters are not stable enough in contact with the ground in some areas, which affects the surveying operation. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a portable surveying device to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a portable surveying device, including a base. A surveying instrument body is mounted on the top of the base, and three rotating seats are rotatably connected to the bottom of the base. Support legs are slidably connected inside the rotating seats. An adjusting plate is slidably connected to one side of each support leg, and an extension plate is rotatably connected to one end of the adjusting plate. A caster wheel is fixedly mounted on one side of the extension plate. A first positioning structure for positioning the adjusting plate is provided on one side of the support leg, and a second positioning structure for positioning the extension plate is provided on one side of the adjusting plate. An opening is provided on one side of the support leg. With a storage slot, the technical effect achieved by the above solution is as follows: by operating the pull plate, the positioning rod is separated from the inside of the positioning hole. Then, the sliding plate is pulled to move it so that one side contacts the bottom of the inner wall of the chute. Then, another set of pull plates is pulled to insert the positioning rod into the inside of the positioning hole for positioning. Then, the second positioning structure is rotated to release the limit on the extension plate, and the extension plate is rotated to make it 90 degrees with the sliding plate. The second positioning structure is rotated to limit the position of the extension plate, so that the caster wheel contacts the ground for movement, making movement easier and more convenient. At the same time, when conducting surveying work.

[0007] Preferably, in any of the above solutions, the adjusting plate includes a sliding plate, two connecting seats are fixedly connected to one side of the supporting leg, a sliding groove is provided on one side of the connecting seat, the sliding plate is slidably connected to the sliding groove, a connecting plate is fixedly connected to one side of the sliding plate, and four positioning holes are provided on one side of the sliding plate. The technical effect achieved by the above solution is that the position of the caster wheel can be adjusted by the sliding plate sliding inside the sliding groove, so that it contacts the ground or is stored inside the storage groove, thereby allowing the position of the caster wheel to be adjusted as needed.

[0008] Preferably, in any of the above solutions, the first positioning structure includes a positioning rod, which is slidably connected to the connecting seat and penetrates the connecting seat. A pull plate is fixedly connected to one side of the positioning rod, and a return spring is fixedly installed on one side of the pull plate. One end of the return spring is connected to the connecting seat. The positioning rod and the positioning hole have the same size. There are two first positioning structures, which are symmetrically distributed on one side of the connecting seat. The technical effect achieved by the above solution is that by operating the pull plate, the positioning rod is separated from the inside of the positioning hole, thereby relaxing the limit on the sliding plate, thereby enabling the vertical positioning of the caster wheel, so that it can stably drive the surveying device to move.

[0009] Preferably, one end of the connecting plate is provided with a groove, which is rotatably connected to the extension plate. An auxiliary groove is provided on one side of the connecting plate, and the second positioning structure is located inside the auxiliary groove. The technical effect achieved by the above solution is that the second positioning structure can be stored in the auxiliary groove, thereby preventing the second positioning structure from colliding with the connecting seat when the caster wheel is being retracted.

[0010] Preferably, in any of the above solutions, the second positioning structure is a bolt, the second positioning structure is threadedly connected to the connecting plate, and one end of the second positioning structure is tangent to one side of the extension plate's rotating shaft. The technical effect achieved by the above solution is: by rotating the second positioning structure, the limitation on the extension plate is relaxed, and the extension plate is rotated to make it 90 degrees with the sliding plate, and the position of the extension plate is limited by rotating the second positioning structure, so that the caster wheel contacts the ground and moves.

[0011] Preferably, the size of the storage slot is larger than the size of the caster wheel. The technical effect achieved by adopting the above solutions is that the storage slot can be used to store the caster wheel when it is not in use.

[0012] Preferably, the inner wall of the slide groove is provided with a plurality of ball bearings, one side of which is tangent to one side of the sliding plate. The technical effect achieved by adopting the above solution is that the ball bearings can reduce the friction of the sliding plate during movement, making adjustment easier and more convenient.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. This portable surveying device, through the cooperation of the base, surveying instrument body, rotating base, support leg, adjustment plate, extension plate, caster wheel, first positioning structure and second positioning structure, enables the surveying device to move by contacting the caster wheel with the ground, making movement easier and more convenient. At the same time, when performing surveying work, the caster wheel can be stored, and the tip of the support leg at the bottom contacts the ground for support, making the support more stable. It can flexibly select the appropriate movement or operation mode according to the required scenario.

[0015] 2. This portable surveying device, through the cooperation between the adjustment plate and the extension plate, enables the omnidirectional wheels to extend and become perpendicular to the support legs when in contact with the ground. This effectively increases the distance between the three omnidirectional wheels, making the surveying device more stable when moving. Attached Figure Description
