Abstract
The utility model particularly relates to a compound focusing device of telescope, the purpose provides a simple structure, graticule scale adjustable compound focusing device of telescope. This focusing device includes the lens cone, and the one end in the lens cone sets up fixed objective group, and the other end sets up fixed eyepiece group, sets up focusing lens group between objective group and the eyepiece group, and focusing lens group is formed apart from adjustable convex lens and concave lens composition by a plurality of each other, set up the graticule between eyepiece group and the focusing lens group, the graticule is the parallel display HUD of transparent, near of graticule sets up miniature projecting lens. Use the projecting lens with scale mark and scale interval projection on the graticule, can be when observing different object adjustment scale mark and scale interval, facilitate the use, in the time need not using the scale mark, can close the projecting lens, the convenient observation more, the while also can be clear when use the telescope night sees the scale interval.
Description
Technical field
This utility model relates to telescope apparatus field, particularly to a kind of telescope compound focusing device.
Background technology
Conventional arrangement have focussing mechanism telescope, owing to its focus adjustment is to be realized by eyepiece group anterior-posterior translation, in eyepiece group moving process, the graticle imaging focal length arranging and being individually fixed on eyepiece group front can not change therewith, therefore, graticle graduation mark is only capable of under specific focal length that blur-free imaging is in visual field, under remaining focal length, plate graduation mark image blur is drawn in differentiation, it is impossible to by graticle scale, observing object picture is carried out graduation measurement.
Scale on graticle of the prior art is usually and uses etching method scale value to be imprinted on graticle, can only change graticle when observing different objects and needing and change scale value or need not graticle, so make telescopical use process bother very much；And when using telescope night, also cannot see the scale on graticle, make telescope be difficult with at night.
Summary of the invention
For the problems referred to above, this utility model purpose is to provide a kind of simple in construction, graticle scale adjustable telescope compound focusing device.
For achieving the above object, this utility model be the technical scheme is that a kind of telescope compound focusing device, including lens barrel, one end in lens barrel arranges fixing objective lens, the other end arranges fixing eyepiece group, arranging focusing lens group between objective lens and eyepiece group, focusing lens group is combined apart from adjustable convex lens and concavees lens each other by multiple；Arranging fixing graticle between described eyepiece group and focusing lens group, described graticle is transparent parallel display HUD, arranges Miniature projection lens near described graticle.
Preferably, arranging flexible solar plate outside described lens barrel, solar panels are connected with accumulator.
Preferably, arranging capacitance touch type adjustment plate outside described lens barrel, adjustment plate is connected with Miniature projection lens.
This utility model has the advantages that graduation mark and scale value are projected on graticle by use projection lens, graduation mark and scale value can be adjusted when observing different objects, convenient use, when need not use graduation mark, projection lens can be closed, more convenient observation, can also be clearly visible that scale value when using telescope night simultaneously.

Fig. 3 is telescope compound focusing device circuit schematic diagram.
Detailed description of the invention
"front", "rear" used herein etc. carry directive vocabulary all for convenience of describing this utility model structure, and this utility model does not do the restriction in any structure.
A kind of telescope compound focusing device as shown in Figure 1-Figure 3, including lens barrel 1, one end in lens barrel 1 arranges fixing objective lens 2, the other end arranges fixing eyepiece group 3, it is characterized in that: arrange focusing lens group 4 between objective lens 2 and eyepiece group 3, focusing lens group 4 is combined apart from adjustable convex lens and concavees lens each other by multiple；The adjustment of focusing lens group 4 can be to arrange gear, leading screw, the manual adjustment mechanism of slide block composition on lens barrel, it is also possible to the automatic mechanism being made up of motor, guide rail, slide block.
Arranging graticle 5 between described eyepiece group 3 and focusing lens group 4, described graticle 5 is transparent parallel display HUD, arranges Miniature projection lens 6 near described graticle 5；Arranging capacitance touch type adjustment plate 9 outside lens barrel 1, adjustment plate 9 is connected with Miniature projection lens 6.
When using telescope focusing, owing to the position of graticle is fixed, therefore the graticle scale moment in eyepiece keeps clear state, convenient observation.Graduation mark and scale value are projected on graticle 5 by Miniature projection lens 6, when needing to adjust scale value or graduation mark precision, can change the image of projection lens 6 projection in adjustment plate 9, to reach to change the purpose of the scale of graticle 5.When need not scale display during observation, close projection lens 6.Due to graduation mark be the ray cast that sends of projection lens 6 on graduated tile 5, the scale on graticle 5 can also be clearly visible that when therefore using telescope night, use more convenient.
In order to make telescope can also use projection lens 6 in the wild, more preferable embodiment is: arrange flexible solar plate 7 outside described lens barrel 1, and solar panels 7 are connected with accumulator 8.Utilize solar energy to provide the electric energy that projection lens 6, adjustment plate 9 need, expand telescopical range.
