Abstract

The utility model relates to a reflection astronomical telescope, which is a new popular telescope. The diameter of an objective lens is 50-80, and a focal distance is 300-600. Scene light in the distance is reflected by an object lens with a concave spherical face to a roof ridge lens, and after the scene light is reflected to a plane mirror by means of diversion. Then the scene light is reflected into an observer's pupil through an eyepiece. The direction of eye light is coincident with the direction of an object, and scenes far and near uniformly become clean positive images. The utility model is characterized in portable use and low fabrication cost, being suitable for being used by primary and secondary school students teachers of a nature lesson in primary schools, teachers of middle school geography, football fans, idolaters, hunters, plantation safeguards, herdsmen, high-voltage wire inspectors and amateur astrophiles.

Description

Reflective astronomical sightseeing telescope

The utility model relates to telescope, particularly reflective astronomical sightseeing telescope.

Existing reflective astronomical telescope bore is all more than 100, and heavy, eye direction and target direction are inequality, and sightseeing is carried in inconvenience; Existing sightseeing telescope all is a refraction type, though the details that can not see moonscape clearly easy to carry promptly enables to see also be that price is higher, is difficult for popularizing.

The purpose of this utility model is: design a kind of bore less, portable, can go sightseeing also can see clearly the telescope that is easy to the popularize moonscape details, that price is lower,

The utility model is by eyepiece stalk, eyepiece, the plane microscope base, level crossing, first lid, first tube, the ridge microscope base, the ridge mirror, landolsring, body tube, end cap, objective tube, object lens, foresight ring and unitor etc. are partly formed, its architectural feature is: the big end of first tube has first being covered with, first tube internal fixation is connecting the ridge microscope base, the ridge microscope base is fixedly being put the ridge mirror, the minute surface of forming two facet mirrors of ridge mirror intersects vertically in opposite directions, its intersection and the first tube that intersects vertically, the center line angle of cut all at 45 of first tube light hole, intersection point overlaps, first tube light hole, the center line of eyepiece stalk is all with the level crossing angle of cut at 45 and be vertically intersected on the minute surface of level crossing, ridge microscope base and first tube are whole naturally two parts, the transverse section of the ridge microscope base by the light hole center line is the planar graph of " people " shape, the one angle is the right angle, all the other two angles are isogonisms, one headgear of body tube is followed the small end of first tube, add a headgear and follow objective tube, object lens are concave spherical mirrors, diameter is between 50～80, focal length is between 300～600, reflecting surface is towards first tube, its optical axis and body tube, the central lines of first tube, the back side of object lens is by the end cap compression set, unitor is connected in center of gravity of the present utility model place, landolsring and foresight ring branch occupy two of body tube, landolsring and foresight ring can be to make so that take out or be inserted in of spring foil metal, also can be to make an integral body naturally simultaneously with first tube and objective tube respectively, make it to be fixedly connected respectively on first tube and objective tube, adjust and promptly can be used for aiming at observed object.

Further specify the utility model below in conjunction with accompanying drawing.

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

The title of each several part among the figure: eyepiece stalk 1, eyepiece 2, plane microscope base 3, level crossing 4, first lid 5, first tube 6, ridge microscope base 7, ridge mirror 8, landolsring 9, body tube 10, end cap 11, object lens 12, objective tube 13, foresight ring 14, unitor 15.

At first by the foresight of foresight ring 14 and the breach aiming distant object of landolsring 9, open first lid 5 again, allow the center line of the parallel first tube 6 of light (a branch of directional light) at a distance inject by end cap 11 and compress the object lens 12 of having had good positioning through the body tube 10 that connecting unitor 15 and objective tube 13, object lens 12 reflect light focusing, reflective taper changes 90 ° direction when arriving ridge mirror 8 on the ridge microscope base 7 penetrates the direction that changes 90 ° when light hole reaches level crossing 4 on the plane microscope base 3 and penetrates eyepiece 2 in the eyepiece stalk 1, goes among observer's the pupil.

The utility model keeps reflective astronomical telescope advantage: achromatism, far and near scenery becomes Picture is clear, and cost is lower, has overcome its shortcoming: the direction of eye and the direction of target be phase not With, imaging is inverted image, heavy; The advantage that has also kept refractor: lighter, The direction of eye is identical with target direction, becomes erect image, and it is clear to observe nearly thing, has overcome it and has lacked Point: or see distant view thing edge blurry, aberration is arranged, see that the details imaging on moon surface is not enough clear Clear, or cost is higher. The utility model is furnished with one ten times go sightseeing eyepiece and one The eyepiece of 40 times observation celestial body. Go sightseeing and when observing the moon, only need this practicality The novel target that on right shoulder, just can watch at the moment of putting; If when observing five stars, can with The screw at coupling of the present utility model center is tightened in the connection of common camera tripod Bolt, so comparatively convenient observation behind the location. The utility model is fit to students in middle and primary schools, primary school Nature teacher, middle school geography teacher, the person of going sightseeing, football fan, star fan, hunter, Plantation bodyguard, shepherd, high-voltage line inspector and amateur astronomer use
