Description
Technical field
The present invention relates to a kind of stadimeter, particularly a kind of laser range finder carries out range observation by laser beam.
Background technology
Laser range finder is the instrument that utilizes laser that the distance of target is accurately measured.Laser range finder penetrates a branch of very thin laser to target when work, by light activated element receiving target laser light reflected bundle, timer is measured laser beam from being transmitted into the time of reception, calculates the range-to-go from the observer.
As shown in Figure 1, sending signal to time of laser instrument from laser controller is t1, and being mapped to the time that target is back to light activated element again from laser instrument is t2, and the time from the light activated element to the signal receiver is t3.In measurement, being mapped to the time t2 that target is back to light activated element again from laser instrument is light signal, and light signal postpones affected by environment hardly.Is electric signal and send signal from laser controller to the time t1 of laser instrument and the time t3 from the light activated element to the signal receiver, and electric signal postpones affected by environment bigger.In order to eliminate the uncertainty of electric signal, a movable reflector is set before laser instrument, when movable reflector is opened, the light directive target that laser instrument sends.Movable reflector rotates to angle among the figure, and the light that laser instrument sends is directly reflected to light activated element, and the time of light flight is t4.Switch two light paths by movable reflector, contrast t2 and t4 can calculate the accurate distance from observer to the target.
On March 12nd, 2008, Granted publication number is the Chinese utility model patent of CN 201035148Y, a kind of laser range finder is disclosed, comprise body and be installed in interior optical path component on the body, in the interior optical path component, reflector is installed on the armature spindle of micromachine, and an end of reflector is pulled on the fixed pin by extension spring, and micromachine is fixed on the interior optical path component by clip.There is following technical matters in this laser range finder:
1, reflector is installed on the armature spindle of micromachine, and the part of stretching out motor because of armature spindle is a cantilever design, and reflector is heavier with respect to the weight of armature spindle, will make armature spindle generation deflection, influences the accuracy of reflector position; The shake of rotor axis of electric itself also can influence the accuracy of reflector position in addition.
2, reflector is installed on the armature spindle of micromachine and an end is pulled on the fixed pin by extension spring, and the deadweight of reflector own requires the staring torque of motor big; Add when the motor-driven reflector rotates, at first will overcome the tension force of extension spring, bring difficulty for the initial start of motor.
3, a coaxial and end tractive has extension spring to reflector with armature spindle, and along with the variation of seasonal temperature, the elasticity of extension spring will change; And the influence very big to the stressed generation of reflector of the service orientation of stadimeter as is in level or plumbness, because the influence of extension spring deadweight, will change to the pulling force of reflector.
4, interior optical path component is not an absolute construction, and it is spacing that the rotational travel of reflector needs other device, otherwise will freely rotate, and angle is excessive.
5, on the optical path component, because the power of micromachine is very little, the gap between rotor and the stator was very little in micromachine was fixed on by clip, and the clip tension will make motor local deformation, and rotor can not rotate; Cross pine, will make the positional misalignment of reflector.Even when debugging, clip is adjusted to suitable elasticity,, stuck or loosening phenomenon still can occurs along with the variation of seasonal temperature.
Summary of the invention
For overcoming problems of the prior art, the invention provides a kind of laser range finder, simple in structure, reliable in action, test result is accurate.
For solving above technical matters, a kind of laser range finder provided by the present invention, comprise body and be installed in interior optical path component on the body, optical path component seat in optical path component comprises in described, micromachine, cylindrical gear, sector gear and movable reflector, described movable reflector is arranged in the cavity of described optical path component seat, its root is provided with the reflector rotating shaft and can rotates to an angle around described reflector rotating shaft, the axle head of described reflector rotating shaft is equipped with described sector gear, described sector gear is meshed with described cylindrical gear, described cylindrical gear is installed on the output shaft of described micromachine, and described micromachine is installed in the motor mounting groove of described interior optical path component seat.
