Abstract

The utility model discloses a direct-irradiating type optical lever indicating device. A stand column is vertically arranged on a base of the indicating device, a lifting platform is installed on the stand column, a fastening screw is used for adjusting the height of the lifting platform, a visible light laser is arranged on the lifting platform in parallel mode, the front end of the visible light laser is connected with the lifting platform through an elastic sheet fixed by the laser, the rear end of the visible light laser is raised or lowered through a high-low dip angle screw, the height of the rear end of the visible light laser is changed so as to adjust the dip angle of an optical axis of the whole visible light laser, a focusing lens is directly fixed at the front end of the visible light laser, and focusing is performed through threads. A semi-transparent scale is fixed on the lifting platform and parallel to the axis of the stand column. The direct-irradiating type optical lever indicating device is provided with visible light for directly indicating scale readings, is wide in view, convenient to debug and operate and strong in result displaying readability, and causes no phenomena of chaos in reading caused by difference in ability of different observers.

Description

A kind of direct-injection type optical lever indicating device

Technical field

The utility model belongs to instrument field, relates to a kind of direct-injection type optical lever indicating device.

Background technology

Optical lever is amplified to observable level through the light path amplification with micro-displacement, is the strong testing tool and the technological means of micro-displacement, deformation.Existing instrument adopts the scale in the catoptron that adheres on the telescope observation optical lever to look like to locate, and this method is because telescopical visual field is very narrow, and the scale reflection image is very dim, and adjustment, focusing be difficulty very; The focusing ability of refractive diopter and eyes that adds everyone is different, causes the eyepiece image-forming range different, and whether if be used for teaching purpose, the inspection of teacher and student and judge condition are inconsistent, cause to exchange difficulty, sometimes be difficult to define and really seen clearly.The scheme that adopts the CCD/CMOS image device to replace the scale image position in the human eye Direct observation telescope is also arranged in recent years, disturb new problems such as observation but on display screen, present sweep trace shake, the noise spot that the imaging of graticule horizontal line is tilted and CCD/CMOS forms in actual the use easily.

Summary of the invention

The utility model is to the deficiency of existing optical lever imaging system, and the catoptron that the laser direct irradiation optical lever of the low intensity visible light wave band that the employing collimation is good is adhered to directly forms the position guidance light on scale label after the reflection.

The technical scheme that the utility model technical solution problem is taked:

A kind of direct-injection type optical lever indicating device comprises visible laser, focusing lens, translucent rule, column, hoistable platform, height inclination angle screw, laser instrument fixedly flexure strip, base and trip bolt.

Vertically be provided with column on the base; Column is equipped with hoistable platform, and trip bolt is used for regulating the hoistable platform height, on described hoistable platform, is arranged with visible laser in parallel; The front end of visible laser through laser instrument fixedly flexure strip link to each other with hoistable platform; The rear end of visible laser changes the rear end height of visible laser through the rising or the reduction of height inclination angle screw, thereby adjusts the inclination angle of whole visible laser optical axis; Focusing lens directly is fixed on the front end of visible laser, and through the screw thread focusing; Translucent rule is fixed on the hoistable platform, with the parallel axes of column.

The utlity model has following advantage: laser technique is ripe; The direct indicating graduation reading of the low intensity visible light laser that is adopted, broad view, debugging, easy to operate; The result shows readable strong, the reading confusion phenomena that does not exist different observers profile difference to cause; Do not rely on external environment light, illumination is strong and weak minimum to observing influence; Used parts are few, and technology is reliable, and is with low cost.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the number of division sign method synoptic diagram of the translucent rule of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Column 4 among Fig. 1 is fixed on the base 9; Hoistable platform 5 is fixed on the column 4 through trip bolt 6; But and oscilaltion, the front end of visible laser 1 through laser instrument fixedly flexure strip 8 link to each other with hoistable platform 5, the rear end of visible laser 1 is through the perhaps reduction of rising of height inclination angle screw 7; Change the rear end height of visible laser 1; Thereby adjust the inclination angle of whole visible laser 1 optical axis, focusing lens 2 directly is fixed on the front end of visible laser 1, and through the screw thread focusing; Translucent rule 3 is fixed on the hoistable platform 5, with the parallel axes of column 4.

Fig. 2 provides the figure notation characteristics of the graduated scale of translucent rule 3, and method simultaneously arranged side by side behind arabic numeral employing regular and the horizon glass picture makes no matter see that from the front still reverse side is seen, all can directly read the arabic numeral of regular.

During use; Rotate the direction adjustment laser beam horizontal level of column 4 slightly; Adjustment hoistable platform 5 is got to the catoptron (being positioned at deformable object) that optical lever is adhered at the height of column 4 with height inclination angle screw 7 control laser beam, and makes laser-bounce arrive the correct position of translucent rule 3.

In the utility model, the reference parameter of each parts is following:

Visible laser 1-" one " word is "+" word (semiconductor) laser instrument perhaps, the red or green beam of emission, the threaded lens in focusing lens 2-edge; Translucent rule 3-transparent hard plate+milky counterdie, band mm or 0.5mm scale, the arabic numeral of scale are made up of as two parts regular and horizon glass; Promptly all can see the arabic numeral of roman in the pro and con both sides of translucent rule 3; Area is bigger to be good, column 4-thicker metal tube, and hoistable platform 5-can be along column 4 metal tube adjustable heights and fixing; The screw that the suitable hand of trip bolt 6-metric thread is twisted; The screw that the suitable hand of height inclination angle screw 7-metric thread is twisted, laser instrument is flexure strip 8-phosphorus bronze sheet fixedly, the Steady base that base 9-quality is big.
