Abstract
The utility model provides a novel parallel light tube. An aperture optical shutter is adopted to make parallel light beams better, thereby making an object clearer. An eye lens group is increased. A unique fine tuning mechanism is adopted to realize horizontal and vertical fine tuning of the parallel light tube when the parallel light tube is adopted as an infinite object or a multi-object. The novel parallel light tube in the utility model can be applied to aspects of the assembly, correction and adjustment of optical instruments.
Description
Technical field
The utility model relates to a kind of novel parallel light pipe, and infinite distance target or multiple goal can be provided.Being the important tool of dress school adjustment optical instrument, also is the important component part in the optics metering equipment.
Background technology
Provided infinite distance target parallel light tube commonly used now adopts and directly graticule is positioned over objective lens focus face, and the back connects lighting lamp device, directly adopts the adjustment adjusting screw to finely tune graticule.The assembling adjustment there are a lot of undesirable defectives to better parallel beam, when using parallel light tube, also have inconvenience in the time of need carrying out adjusting about graticule reaches up and down to parallel light tube adjustment such as spirit-leveling instrument, total powerstation for example.
The utility model content
The purpose of the utility model: aim to provide a kind of target clear, proofread and correct infinite distance target or multiple goal parallel light tube can be provided more easily.
The utility model, adopting aperture optical gate (13,15), making parallel beam more superior is that target is more clear; Increase eyepiece group (11), adopt unique micro-adjusting mechanism, make when utilizing parallel light tube as the infinite distance target; About can carrying out parallel light tube in real time, about fine setting, it is characterized in that: the different aperture optical gate (13,15) of the one or more bores of increase between objective lens (1) and graticule (8); Increase eyepiece group (11) at graticule (8) rear side, illuminating lamp (13) places illuminating lamp holder (12) to be enclosed within on the mirror pipe bonnet (10), adopts connecting rod (14; 15) and two bases (19,22) but and fine motion band circular arc pillar (20), fine setting seat (16) mechanism.
Description of drawings
Figure is a structural representation.
1. objective lens among the figure, 2. trim ring, 3. fore-stock holding screw, 4. the aperture optical gate 1,5. the mirror pipe; 6. the aperture optical gate 2,7. after-poppet holding screw, 8. graticule, 9. graticule adjusting screw, 10. mirror pipe bonnet; 11. the eyepiece group, 12. illuminating lamp holders, 13. illuminating lamps, 14. connecting rods, 1,15. connecting rod 2; 16. fine setting seat (being with adjusting screw up and down), 17. attachment screws, 18. after-poppets, 19. base plates 1, but 20. fine motion band circular arc pillars; 21. fore-stock, 22. base plates 2 (front and back support 21,18 is fixed on this plate), 23. mirror pipe front shrouds, 24. lighting lamp power lines, 25. base plates 1 and base plate 2 attachment screws
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment
In said structure; Between objective lens (1) and graticule (8), increase the different aperture of one or more bores and explain (13; 15); Increase eyepiece group (11) at graticule (8) rear side, change aperture optical gate quantity and aperture sluice gate footpath, increase graticule quantity can provide many focal lengths target by a parallel light tube.
In said structure, illuminating lamp (13) places illuminating lamp holder (12) to be enclosed within on the mirror pipe bonnet (10) of eyepiece group (11) through hole.
In said structure; Adopt two connecting rods (14; 15) and two bases (19; 22) but and fine motion band circular arc pillar (20), fine setting seat (16) mechanism through adjustment fine setting seat (16) to parallel light tube graticule (8) accurately adjustment up and down; Wherein connecting rod 1 (14) is connected with mirror pipe (5), connecting rod 2 (15) is connected with after-poppet (18); Connecting rod 1 (14) and connecting rod 2 (15) are screwed, and fore-stock (21) and after-poppet (18) are screwed respectively and are contained on the base plate 2 (22), and front end fine motion band circular arc pillar (20) also can be made of one with base plate 2 (22) but fine motion band circular arc pillar (20) is positioned at base plate 1 (19); Base plate 1 with base plate 2 attachment screws (25) but be connected base plate 1 (19) and base plate 2 (22) through fine motion band circular arc pillar (20), fine setting seat (with adjusting screw up and down) (16) downside and base plate 1 (19) with attachment screw (17) fix, upside and base plate 2 (22) are connected, finely tune spacing base plate 2 (22) connecting portions of screw up and down of (with adjusting screw up and down) (16).
Claims (1)
1. novel parallel light pipe; It is characterized in that: between objective lens and graticule, increase the different aperture optical gate of one or more bores; Increase the eyepiece group at differentiation plate rear side; Illuminating lamp places illuminating lamp holder, be enclosed within on the mirror pipe bonnet of eyepiece group through hole, but package unit adopts two connecting rods and two bases and fine motion band circular arc pillars and finely tunes seat mechanism the parallel light tube graticule is accurately adjusted up and down.
