Abstract
The utility model relates to a laser perpendicularity and horizontality indicator, which can display a light vertical line, a horizontal line, a cross line and a light spot. The utility model is formed by orderly connecting a base, a main body and an optical head, wherein, the inside of the main body is provided with a laser source with a red wave length and a green wave length, an auxiliary circuit and a motor, and the optical head is a rotor and is fixed on the main body. The optical head is provided with four light emitting holes which respectively form the light vertical line, the horizontal line, the cross line and the light spot.
Description
The utility model relates to multiple geometric luminous ray instruments such as the vertical light of a kind of demonstration, horizontal light, cross light, luminous point.Be particularly related to and utilize laser as showing various geometric instruments.
Adopt semiconductor laser quite universal as the instrument of geodetic surveying, engineering construction.Such as Geoplane is exactly to obtain horizontal line by rotation, but this scanner function is too simple, and owing to adopt single long wavelength laser as light source, its brightness is not high.The application scenario is restricted, can only light than the darkroom in or specific environment use.Occasion outdoor or that light is stronger then can not be used, and reason is that bias light is too strong, and the wavelength of light of emission is long partially, and power is again little, so do not see the red light that scanner is launched in occasion outdoor or that light is stronger, can't use.
The purpose of this utility model provides the high green laser of a kind of human eye sensitivity and does light source and have red light source simultaneously concurrently, realizes that promptly double-wavelength light source is with the laser vertical that adapts to different occasions, horizontal indicator.These light source scioptics pool a branch of directional light, and directional light forms light vertical line, light horizontal line, light cross curve, luminous point figures respectively by catoptron and four light-emitting windows of shaven head.The irradiation that utilizes luminous point simultaneously can be measured the surface level of any occasion by a cooperation light target, and the operation diameter can reach more than 200 meters.
The utility model is finished like this:
This instrument is made up of support, fuselage, bare headed three parts, and is furnished with a cooperation light target.Fuselage is installed on the support, shaven head is positioned at the fuselage top, four light holes that can carry out 90 ° and 360 ° rotations are arranged on the shaven head, the light source of being made up of laser instrument and driving circuit is screwed in fuselage interior, this light source and light conducting cylinder, catoptron, light hole are formed light-source system, and the motor and gearing, bearing, the shaven head that are screwed in fuselage connect to form rotary system.The cooperation light target is made up of three photodetectors, circuit, lens, batteries.
The shaven head LASER Light Source adopts red, green double-colored wavelength.
The green laser and the red laser of semiconductor laser emission shine on the catoptron by light conducting cylinder, and light forms reflection at this, and this light penetrates through shaven head.
Shaven head is rounded, and inside is equipped with four in order to produce the lens of different optical pattern, and moving 90 degree of its revolution promptly produce a kind of figure, make figure be respectively light vertical line, light horizontal line, light cross curve, luminous point.Specifically be when producing an elongated vertical light during by a horizontal wide-angle cylindrical mirror through the directional light of catoptron.When directional light will produce an elongated horizontal line during by a vertical wide-angle cylindrical mirror.When directional light will produce the light cross curve during by a cross wide-angle cylindrical mirror.
The utility model is compared its advantage with other existing instruments and is:
1, change over green, red two kinds of visible light sources by single red laser, especially green laser is short because of its wavelength, the brightness height can be used on outdoor and high light under.
2, form light vertical line, light horizontal line, light cross curve, luminous point by the wide-angle cylindrical mirror, can satisfy various requirement of engineering.Particularly owing to adopt its emission angle maximum of wide-angle cylindrical mirror can reach 90 degree, minimum also can be no more than 40 degree and have the general emission angle of scanner now more than 40 degree.
3, because the cooperation light target is arranged, so can measure 200 meters of diameters with interior any surface level.
4, this apparatus structure is simple, is convenient to operation, and function is many, and cost is low.
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 is the utility model diagrammatic cross-section.
See Fig. 1, the utility model is an integral body by support (summary), shaven head 1, light conducting cylinder 5, and is fixing with fuselage 6 through bearing 7.Shaven head 1 can rotate flexibly, and the directional light of light source 9 emissions is mapped on the catoptron 4 through light conducting cylinder 5, and this light beam forms the geometric figure light that needs along unthreaded hole 3 outputs of reflection angle through shaven head 1.Motor 8 drives i.e. shaven head 1 rotation of light conducting cylinder 5 by gearing 10, makes its spot scan by the non-spherical lens of shaven head become the light of one 360 degree.
Lasing light emitter of the present utility model is high green laser of human eye sensitivity and red laser.This light source forms light perpendicular line, light horizontal line, light cross curve and luminous point respectively by four wide-angle cylindrical mirrors.And can form one 360 ring of light line of spending by the rotation of shaven head.
The green laser of LASER Light Source employing wavelength 500nm-560nm of the present utility model and emission wavelength are greater than the red laser of 651nm.
Its emission angle of wide-angle cylindrical lens of the present utility model is the 60-90 degree.
