Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire-fighting laser rangefinders, in particular to a laser rangefinder for fire-fighting detection. Background Art
[0002] Laser rangefinders are divided into phase method rangefinders and pulse method rangefinders according to the distance measurement method. When working, the pulse laser rangefinder emits a beam or a series of short pulse laser beams to the target. 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. The 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.
[0003] The existing Chinese patent with publication number CN212060573U discloses a laser rangefinder, including a display screen, function buttons, a handle, a shell, a control system, two laser emitting holes and two laser receiving mirrors. The display screen is arranged on one side of the shell, the handle is fixed to the lower end of the shell, the function buttons are arranged on the shell, one laser emitting hole and a laser receiving mirror are arranged on the left side of the shell, and the other laser emitting hole and a laser receiving mirror are arranged on the right side of the shell. The laser emitting holes on the left and right sides emit lasers at the same time, and the laser receiving mirrors on the left and right sides receive lasers at the same time.
[0004] With regard to the above-mentioned related technologies, the inventor's laser rangefinder needs to be constantly moved when used in fire detection, so most of the distance measurement operations are performed manually by hand. Handheld distance measurement requires that the rangefinder be kept in a horizontal state at all times, and this measurement method is likely to cause hand fatigue of the staff over a long period of time.
