Abstract
The utility model relates to an optical telescope, in particular to a binocular telescope, comprising a shell, the upper end of which is provided with two parallel eyepiece frames and the lower end of the shell is provided with two objective lens frames. The objective lens is arranged inside the objective lens frame. The shell is provided with a main lens and a regulating device. The utility model is characterized in that: an eyepiece regulating disk connected to the shell through a rotating axis is arranged on the eyepiece frame; a plurality of groups of eyepiece lenses are arranged corresponding to a disc, wherein, the position of the eyepiece lenses corresponds to the position of the eyepiece frame. The utility model mainly solves the technical problems that the prior binocular telescope can only regulate the focal length through a regulating mechanism; the regulating range is limited by the eyepiece, objective lens and the main lens. The utility model further enlarges the focal length regulating range of the telescope through the changeable eyepiece structure.
Description
Technical field
The utility model relates to optical telescope, particularly a kind of binoculars.
Background technology
Binoculars are called binocular again, and it is clear bright that it has imaging, and advantages such as the visual field is big, easy to carry, low price are suitable for the astrophile and are used for touring the heavens and observe planar celestial bodies such as nebula, cluster, comet very much.When observing with binocular the sunny night of not having month, visible among wide visual field an array of stars gather, have one, two nebula, cluster to intersperse once in a while, it is proper to make us the spacious god of the heart.
What binocular adopted is dioptric system, can be divided into two kinds of Galileo formula and Kepler's formulas.Galileo formula binocular is simple in structure, and optical energy loss is little, lens barrel is short, price is also lower, and still, its magnification generally can not surpass 6 times, and magnification increases again, and the visual field will reduce rapidly, the field of view edge deepening.Image quality also can descend, so this binocular is used less.Kepler's formula binocular commonly now, its visual field is bigger than Galileo formula, and imaging is more clear, but what Kepler's formula binocular became is the picture that stands upside down, in order to obtain erect image, be added with image rotation prism or image rotation lenses in its light path, these image rotating devices are absolutely necessary in ground observation.But falling of picture is unimportant over against astronomy, but erect image telescope can look for star braid to come conveniently to the beginner.
As Chinese utility model patent instructions (Granted publication number: CN2758802Y) provide a kind of binoculars, comprised eyepiece, governor motion and main mirror, main mirror lid, lower cover have respectively been arranged on two main mirrors and the object lens frame of object lens is housed; Main mirror is hinged by axis; Governor motion contains regulates picture frame, adjusting screw(rod), steel band, belt, handwheel, axis, belt pulley, sliding sleeve, sealing foreskin, slide-bar etc.; Main mirror lid and main mirror constitute power train casing and optical texture part seal isolation; Two main mirrors cover and are equipped with left and right adjusting screw(rod) and have steel band to connect, and fast accent spanner handle is housed on right adjusting screw(rod); Be fixed with handwheel and belt pulley on the axis; Belt pulley has the belt of connection with right adjusting screw(rod); The right side main mirror cover along in axis be equipped with sliding sleeve and slide-bar; The adjusting picture frame of eyepiece is housed by screw fit on the adjusting screw(rod), regulates picture frame and be connected with slide-bar.Because governor motion and optical system seal isolation, waterproofly can not cause bite again; Focusing adopts steel band, belt and multi-step thread to conduct fast, divides general handwheel and fast two modes of transferring, and can focus fast.
From existing product structure, the adjusting of focal length mainly is to realize by governor motion, is under the situation of fixing len for eyepiece, object lens and main mirror, and the scope of adjusting is exactly in the adjustable extent of these eyeglasses, does not further regulate leeway.
The utility model content
The purpose of this utility model is to provide a kind of binoculars, mainly solve existing binoculars and can only realize the adjusting of focal length by governor motion, and the scope of regulating will be subjected to the technical matters of eyepiece, object lens and the restriction of main mirror range of adjustment, by removable goggle structure, further increased telescopical focus adjustment scope.
For addressing the above problem, the utility model is achieved in that
A kind of binoculars, it comprises a housing, this housing upper end two eyepiece frames that be arranged in parallel, the lower end two object lens frames that be arranged in parallel are provided with object lens in the object lens frame; Polygonal mirror main body and governor motion are set in this housing, it is characterized in that: an eyepiece is set on this eyepiece frame regulates disk, this disk is connected on the housing by turning axle, and this disk correspondence is provided with some groups of eyepiece eyeglasses, and the position of this eyepiece eyeglass is just corresponding to the aperture position of eyepiece frame.
Described binoculars is characterized in that: the area of this eyepiece eyeglass is more than or equal to the eyepiece frame opening.
Described binoculars is characterized in that: this eyepiece eyeglass presents circular array and arranges.
By technique scheme, the beneficial effects of the utility model are:
The utility model be except can being undertaken the focus adjustment by governor motion, can also rotate eyepiece and regulate disk and change the eyepiece group and further regulate, and so just can increase the adjustable extent of focal length.

Embodiment
See also Fig. 1,2, the utility model discloses a kind of structural representation of binoculars.As shown in the figure: it comprises a housing 1, this housing 1 upper end two eyepiece frames 21,22 that be arranged in parallel, and the lower end two object lens frames 31,32 that be arranged in parallel are provided with object lens 311,321 in the object lens frame 31,32; Polygonal mirror main body 4 and governor motion 5 are set in this housing 1, it is characterized in that: an eyepiece is set on this eyepiece frame 21,22 regulates disk 6, this disk 6 is connected on the housing 1 by turning axle 7, and these disk 6 correspondences are provided with some groups of eyepiece eyeglasses 211,221, and the position of this eyepiece eyeglass 211,221 is just corresponding to the aperture position of eyepiece frame 21,22.The area of this eyepiece eyeglass 211,221 is more than or equal to eyepiece frame 21,22 openings, and this eyepiece eyeglass 211,221 presents circular array and arranges.
During use, except can being undertaken the focus adjustment, can also rotate eyepiece and regulate disk 6 and change the eyepiece group and further regulate, so just can increase the adjustable extent of focal length by governor motion 5.
