Description

Technical Field

[0001] The utility model relates to a positioning carrier for assembly, in particular to a positioning carrier for assembly of a laser rangefinder, belonging to the technical field of laser rangefinders. Background Art

[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 when working. 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 propagating in space.

[0003] When the upper cover on the top of the laser rangefinder needs to be fixed to the laser rangefinder by screws, the upper cover needs to be aligned with the top of the laser rangefinder first. However, the existing operation method is manual positioning by personnel, which may cause deviation when screwing, and the personnel need to position and align again, which is troublesome. Therefore, a positioning carrier for assembling the laser rangefinder is designed. Utility Model Content
