Description

Technical Field

[0001] The utility model relates to the technical field of laser rangefinders, in particular to a laser rangefinder for surveying and mapping. Background Art

[0002] In the field of surveying and mapping, laser rangefinder has become an indispensable measuring equipment with its high precision and high efficiency. It uses the emission and reception of laser beams to accurately measure the distance of the target object by calculating the time difference of the laser's round trip. Laser rangefinder can not only provide accurate measurement data in indoor environments, but also operate stably in complex outdoor environments. It is suitable for multiple scenarios such as building measurement, topographic surveying and mapping, and environmental monitoring. Its non-contact measurement method not only improves work efficiency, but also avoids the errors that may be caused by traditional measurement methods. With the continuous advancement of technology, the performance of laser rangefinders has been continuously improved, which has brought great convenience to surveying and mapping work.

[0003] However, traditional laser rangefinders often have many inconveniences in angle adjustment. The traditional adjustment method usually requires the overall rotation of the device, which not only easily causes the position of the device to shift, but also requires staff to recalibrate, greatly reducing work efficiency. In addition, uneven ground is also a common problem, which may cause the angle of the laser rangefinder to be unable to remain horizontal, thereby affecting the accuracy of the measurement results.

By pressing the pressure plate 14 and rotating the rotating handle 11, the angle adjustment of the laser rangefinder 7 can be achieved, which reduces the trouble of calibration and effectively avoids the problem of device position offset. The original laser rangefinder adopts an overall rotation method to adjust the angle, which not only easily causes the device position to offset, but also requires the staff to recalibrate, which greatly reduces the traditional method of working efficiency. Moreover, the laser rangefinder 7 is a known technology and its internal structure is not improved.

[0029] The supporting mechanism includes a fixed block 18, a connecting rod 19, a slider 20, a threaded rod 21, a knob 22, a base 23 and a slide 24. The base 23 is provided with a slide 24, and the slide 24 is slidably connected to the slider 20. The base 23 is rotatably connected to the threaded rod 21, and the threaded rod 21 is fixedly connected to the knob 22. The threaded rod 21 is threadedly connected to the slider 20. The slider 20 is hinged with the connecting rod 19, and the connecting rod 19 is hinged with the fixed block 18. The fixed block 18 is fixedly connected to the lower end of the bottom plate 1. The rotating shaft 5 is fixedly connected to the chassis 6, and the chassis 6 is fixedly connected to the laser rangefinder 7. The laser rangefinder 7 is arranged at the upper end of the chassis 6, and there are four groups of connecting rods 19, which are arranged between the fixed block 2 18 and the slider 20. The turntable 1 8 is fixedly connected to the turntable 2 10, and the turntable 2 10 is fixedly connected to the rotating handle 11. The limiting groove 9 is arranged at the lower end of the rotating shaft 5, and the turntable 2 10 is arranged at the lower end of the limiting groove 9. The rotating handle 11 is evenly arranged on the turntable 2 10. There are two groups of supporting mechanisms, and the supporting mechanisms are evenly arranged at the lower end of the main mechanism. The threads on the threaded rod 21 are arranged in reverse, and the slider 20 is symmetrically arranged inside the slide groove 24.

[0030] Working principle: First, the user presses the upper end of the pressure plate 14 to drive the guide shaft 13 to slide into the inside of the fixing frame 4, and the guide shaft 13 squeezes the spring 12 to compress the spring 12, and the other end of the pressure plate 14 rises, and the pressure plate 14 drives the connecting shaft 16 to move, and the connecting shaft 16 drives the limit block 17 to disengage from the inside of the limit groove 9, and then the rotating handle 11 is turned by hand, and the rotating handle 11 drives the turntable 2 10 to rotate, and the turntable 2 10 drives the turntable 1 8 to rotate, and the turntable 1 8 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the chassis 6 to rotate, and the chassis 6 drives the upper laser rangefinder 7 to rotate. At this point, the angle of the laser rangefinder 7 is adjusted, and the original traditional method of directly fixing the laser rangefinder 7 is changed. If necessary To rotate the angle of the laser rangefinder 7, the entire device needs to be rotated, which can easily cause the position of the device to shift, so that the staff needs to recalibrate the position of the laser rangefinder 7, which brings inconvenience to use. Finally, by rotating one of the sets of knobs 22, the threaded rod 21 is driven to rotate. Because the threads on the threaded rod 21 are set in opposite directions, the slider 20 can only slide inside the slide groove 24 in the back or opposite directions. The sliding of the slider 20 rotates the angle of the connecting rod 19. The rotation of the connecting rod 19 raises or lowers one end of the bottom plate 23, which is convenient for adjusting the laser rangefinder 7 to a horizontal angle according to the site, so as to avoid the uneven ground causing the angle of the laser rangefinder 7 to be not in a horizontal state, resulting in inaccurate measurement results.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
