Description

Technical Field

[0001] This utility model relates to the field of search and rescue device manufacturing technology, and in particular to a rangefinder for cadastral surveying. Background Technology

[0002] A cadastral surveying rangefinder is a precision measuring instrument specifically designed for the field of cadastral surveying. It accurately measures the horizontal or slant distance between points on the ground by emitting and receiving light waves (such as lasers or infrared rays), and combines this with angle measurement data to determine information such as land boundaries, area, and location, providing an accurate geometric data basis for land management, property registration, and urban planning.

[0003] In cadastral surveying, rangefinders need to be stably placed in complex terrain in the field. Traditional supports rely on manually adjusting the height of multiple legs, which is cumbersome, time-consuming, and difficult to ensure accurate leveling. In particular, uneven ground can easily introduce measurement errors. Existing equipment lacks an efficient mechanism for simultaneous deployment and retraction, and the handling and preparation work is arduous.

[0004] Therefore, how to provide a rangefinder for cadastral surveying is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a cadastral surveying rangefinder that uses a motor-driven threaded rod and linkage mechanism to automatically and synchronously unfold and retract the support legs, quickly forming a stable support. Its independently adjustable support leg structure can adapt to uneven ground, ensuring the equipment is level and stable, significantly improving leveling efficiency and measurement accuracy. At the same time, the folding design facilitates transportation, thus solving the problems mentioned in the background art.

[0006] A cadastral surveying rangefinder according to an embodiment of the present utility model includes a base plate and a platform plate. A level is provided at the center of the front side of the platform plate. A rotating disk is rotatably connected to the center of the top of the platform plate. The rangefinder body is provided at the top of the rotating disk. A rotating motor is fixedly connected to the center of the bottom end of the platform plate. A threaded rod is fixedly connected to the output end of the rotating motor.

[0007] As a preferred embodiment of this utility model: the outer wall of the threaded rod is threadedly connected to a threaded sleeve, and the outer wall of the threaded sleeve is fixedly connected to a plurality of second hinge members.

[0008] As a further preferred embodiment of this utility model: one end of a connecting rod is hinged to the inner wall of the second hinge member, and the end of the connecting rod away from the second hinge member is hinged to a hinge member.

[0009] As a further preferred embodiment of this utility model: a first connecting rod is fixedly connected to the outer wall of the hinge, and a rotating rod is fixedly connected to the outer wall of the top end of the first connecting rod.

[0010] As a further preferred embodiment of this utility model: the rotating rod is rotatably connected to the platform plate, and a second connecting rod is slidably connected to the inner wall of the first connecting rod.

[0011] As a further preferred embodiment of this utility model: a support rod is fixedly connected to the top center of the base plate, the inner wall of the support rod is rotatably connected to a threaded rod, and a brake wheel is fixedly connected to the bottom end of the base plate.

[0012] As a further preferred embodiment of this utility model: multiple protective sleeves are fixedly connected to the bottom of the outer wall of the support rod, and the inner wall of the protective sleeve is provided with a connector.

[0013] As a further preferred embodiment of this utility model: a plug is fixedly connected to the bottom end of the second connecting rod, and a plug-in fastener is fixedly connected to the bottom of the outer wall of the first connecting rod.

[0014] The beneficial effects of this utility model are:

[0015] This cadastral surveying rangefinder uses a rotating motor to drive a threaded rod, which in turn moves a threaded sleeve. This movement is then synchronized through a hinged linkage mechanism, which unfolds multiple sets of first and second connecting rods to form a stable support structure. Combined with independently adjustable plug-in fasteners, it can adapt to uneven ground, effectively improving the stability and leveling accuracy of the rangefinder. The overall structure is electrically controlled for unfolding and folding, making operation simple and quick, reducing the time spent on manual leveling in traditional surveying, and improving surveying efficiency. Furthermore, its folding design facilitates transport and storage, making it highly practical and applicable to engineering projects. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a cadastral surveying rangefinder includes a base plate 1 and a platform plate 7. A level 10 is installed at the center of the front side of the platform plate 7. A rotating disk 8 is rotatably connected to the center of the top of the platform plate 7. The rangefinder body 9 is installed on the top of the rotating disk 8. A rotating motor 16 is fixedly connected to the center of the bottom of the platform plate 7. A threaded rod 12 is fixedly connected to the output end of the rotating motor 16. A threaded sleeve 19 is threadedly connected to the outer wall of the threaded rod 12. A plurality of second hinge members 15 are fixedly connected to the outer wall of the threaded sleeve 19. One end of a connecting rod 5 is hinged to the inner wall of the second hinge member 15. A hinge member 4 is hinged to the end of the connecting rod 5 away from the second hinge member 15. A first connecting rod 4 is fixedly connected to the outer wall of the hinge member 4. The first connecting rod 6 has a rotating rod 17 fixedly connected to its top outer wall, which is rotatably connected to the platform plate 7. The second connecting rod 3 is slidably connected to the inner wall of the first connecting rod 6. The support rod 2 is fixedly connected to the top middle of the base plate 1, and the inner wall of the support rod 2 is rotatably connected to the threaded rod 12. The bottom of the base plate 1 is fixedly connected to a brake wheel 14. The bottom of the outer wall of the support rod 2 is fixedly connected to multiple protective sleeves 13, and the inner wall of the protective sleeves 13 is provided with a plug connector 18. The bottom of the second connecting rod 3 is fixedly connected to a plug connector 18. The bottom of the outer wall of the first connecting rod 6 is fixedly connected to a plug-in fastener 11. The device is also equipped with a brake wheel 14 at the bottom for easy movement.

[0024] Working principle:

[0025] First, the rotation motor 16 is started to drive the threaded rod 12 at its output end to rotate. The rotation of the threaded rod 12 drives the threaded sleeve 19 on the outer wall to move. The movement of the threaded sleeve 19 drives the multiple second hinges 15 on the outer wall to move. The movement of the second hinges 15 drives the connecting rod 5 to move towards one end of the second hinge 15. The first connecting rod 6, and the rotating rod 17 at the top of the first connecting rod 6, rotate with the platform plate 7. The movement of the connecting rod 5 causes the first connecting rod 6 and the second connecting rod 3 to rotate outward with the rotation point between the rotating rod 17 and the platform plate 7 as the center. Then, by adjusting the plug-in fixing piece 11, the height of a single second connecting rod 3 and the first connecting rod 6 can be adjusted to prevent uneven ground from affecting the test data. Conversely, starting the rotation motor 16 to rotate in the opposite direction can achieve the retraction.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
