[0002] Laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. According to the distance measurement method, it is divided into phase method rangefinder and pulse method rangefinder. Pulse laser rangefinder emits a beam or a series of short pulse laser beams to the target during operation. The laser beam reflected by the target is received by the photoelectric element. The timer measures the time from the emission to the reception of the laser beam and calculates the distance from the observer to the target. Phase method laser rangefinder detects the distance by detecting the phase difference between the emitted light and the reflected light when they propagate in space.

[0037] By rotating the threaded mounting seat 42 and under the action of the thread of the threaded column 3 41 , the lower protective shell 44 and the rangefinder body 2 are driven to move up and down, and the anti-sliding block 43 is used to prevent the threaded mounting seat 42 from slipping when rotating.

[0038] The distance measuring device is fixed and protected by the lower protective shell 44 and the upper protective shell 45, and the level meter 46 is used to display whether the device is level, thereby ensuring the accuracy of horizontal distance measurement. The level meter 46 is an existing mature product.

[0039] The motor 47 drives the gear column 48 to rotate, and the gear column 48 drives the gear ring 49 to rotate, thereby realizing the synchronous rotation of the lower protective shell 44 and the rangefinder body 2, so that the detection end of the rangefinder body 2 rotates horizontally to sweep a specific angle, thereby performing accurate laser ranging of the surroundings.

[0040] The anti-sliding block 43 is prevented from colliding with the mounting plate 1 when the threaded mounting seat 42 is rotated, and the distance is measured through the rangefinder body 2 .

[0041] If it is necessary to measure the distance on an uneven ground, the position of the second threaded barrel 313 relative to the mounting plate 1 is adjusted according to actual needs to achieve the angle adjustment of the second support frame 310 and the first support frame 33. At the same time, the position of the threaded barrel 38 relative to the threaded column 37 is adjusted to adapt to the uneven ground and ensure the horizontal posture of the mounting plate 1 as much as possible, thereby achieving leveling.
