Description

Technical Field

[0001] This utility model relates to the field of laser rangefinder technology, and more specifically, to a laser rangefinder calibration device. Background Technology

[0002] A laser rangefinder is an instrument that measures the distance to a target by modulating a specific parameter of a laser beam. A pulsed laser rangefinder emits one or more short pulses of laser light towards the target. A photoelectric element receives the reflected laser beam, and a timer measures the time from emission to reception to calculate the distance from the observer to the target. However, laser rangefinders require calibration before measurement. Existing laser rangefinders often lack sufficient calibration data, making it difficult to calculate the ranging accuracy using calibration data from multiple locations. This results in an inaccurate fitting calibration curve.

[0003] Existing technologies have poor clamping effects when clamping laser rangefinders. To solve the above problems, we have introduced the following device. Utility Model Content

[0026] By adopting the above technical solution, the laser rangefinder calibration device, through the setting of the fixing mechanism 5, when people need to fix the laser rangefinder body 4, they only need to snap the laser rangefinder body 4 into the limiting groove 3, and then rotate the turntable 504, thereby driving the first threaded post 505 to rotate. With the cooperation of the first threaded post 505 and the threaded tube 506, the connecting plate 501 carrying the pressure plate 508 is moved. After the pressure plate 508 has fixed the laser rangefinder body 4, people only need to stop rotating the turntable 504, ensuring that the laser rangefinder body 4 maintains a stable state during the test.

[0027] Specifically, a fixed platform 7 is fixedly connected to the upper surface of the base 1, a motor base 8 is fixedly connected to the side of the fixed platform 7, a forward and reverse motor 9 is fixedly connected to the upper surface of the motor base 8, a second rotating shaft 11 is fixedly connected to the other end of the output shaft of the forward and reverse motor 9, a second bearing 10 is provided through the surface of the fixed platform 7, the second rotating shaft 11 is provided through the second bearing 10, a second threaded post 12 is fixedly connected to the other end of the second rotating shaft 11, a third rotating shaft 13 is fixedly connected to the other end of the second threaded post 12, a third bearing 14 is fixedly connected to the side of the support platform 2, the other end of the third rotating shaft 13 is provided through the third bearing 14, a threaded cap 15 is threadedly connected to the surface of the second threaded post 12, a movable platform 16 is fixedly connected to the side of the threaded cap 15, and a reflector 6 is fixedly connected to the upper surface of the movable platform 16.

[0028] By adopting the above technical solution, this laser rangefinder calibration device, through the setting of a forward and reverse motor 9, a second threaded post 12, and a threaded cap 15, allows users to calibrate the laser rangefinder body 4 by simply controlling the forward and reverse motor 9 via the control switch 20. This drives the second threaded post 12 to rotate, and with the cooperation of the second threaded post 12 and the threaded cap 15, the movable platform 16 carrying the reflector 6 moves. By repeatedly adjusting the position of the reflector 6, the laser rangefinder body 4 can be calibrated, reducing the workload of users.

[0031] The working principle of this utility model is as follows: In use, users simply need to move the device to a suitable position and connect it to an external power source. When fixing the laser rangefinder body 4, users simply need to engage it in the limiting groove 3, then rotate the turntable 504, thereby rotating the first threaded post 505. With the cooperation of the first threaded post 505 and the threaded tube 506, the connecting plate 501 carrying the pressure plate 508 moves. Once the pressure plate 508 has fixed the laser rangefinder body 4, users simply need to stop rotating the turntable 504. To ensure the laser rangefinder body 4 remains stable during testing, when calibration is required, the user only needs to control the forward and reverse motors 9 via the control switch 20, which in turn drives the second threaded column 12 to rotate. With the cooperation of the second threaded column 12 and the threaded cap 15, the movable platform 16 carrying the reflector 6 moves. By repeatedly adjusting the position of the reflector 6, the laser rangefinder body 4 can be calibrated, reducing the user's workload. At the same time, with the cooperation of the slide rod 19 and the sliding sleeve 18, the movable platform 16 carrying the reflector 6 moves in a directional manner.
