Abstract
The utility model discloses a finderscope support of an astronomical telescope. The finderscope support comprises a sleeve arranged at the outer ring of the finderscope and a support seat connected to the lower side of the sleeve. One end of the sleeve is provided with a plurality of notches that are distributed along the circumference of the outer surface of the sleeve; and the end portion of the sleeve is segmented to form a plurality of branch blocks by the notches. And the other end of the sleeve is provided with a plurality of threaded through holes that are distributed along the circumference of the outer surface of the sleeve; and adjusting screws are arranged in the threaded through holes. Because the end portion of the sleeve is segmented by the notches to form the plurality of branch blocks, the adjusting screws of the sleeve are adjusted and the end portion, with the threaded through holes, of the sleeve is lifted; the end portions of the branch blocks of the sleeve are clamped by the finderscope; and the adjusting screws are selected for adjusting according to demands. Therefore, the finderscope can be conveniently adjusted to be synchronous with the main telescope; the adjustment can be carried out easily, conveniently, and rapidly; the direction is clear; and the structure is simple.
Description
Technical field
The utility model relates to a kind of support, relates in particular to a kind of supporting structure of astronomical telescope finder.
Background technology
Heavy caliber telescope is because multiplying power is high, and visual field is little, searches object observing, especially Celestial Objects difficulty especially, so must add small-bore, low range, the finder of visual field greatly on primary telescope lens barrel, is used for searching celestial body to be observed.The effect of finder is that celestial body to be observed is directed to primary telescope visual field central authorities.In order promptly to search celestial body to be observed, need to regulate its optical axis parallel with primary mirror optical axis by finder bracket, the congruence that finder and primary mirror are observed.The bracket adjustment method of prior art is, finder is inserted to finder bracket, by the set screw on adjusting pole, finder cross differentiation plate overlapped with the interior center of selected primary telescope range of observation target.But this method is unfixing on support because of finder, is difficult to finder to adjust to primary telescope and synchronize, and during adjusting, direction is indefinite, sometimes cannot realize synchronous at all.
Utility model content
Problem to be solved in the utility model is, for prior art finder, be difficult to adjust to primary telescope and synchronize, the indefinite defect of direction during adjusting, when a kind of adjusting is provided, direction is clear and definite, conveniently finder is adjusted to the astronomical telescope finder bracket of synchronizeing with primary telescope.
The purpose of this utility model is achieved through the following technical solutions.Astronomical telescope finder bracket, comprise the carrier base that is arranged on the sleeve of finder outer ring and is connected to sleeve downside, one end of described sleeve is provided with some notches that circumferentially distribute along sleeve outer surface, some pieces of rear formation are cut apart by notch in the end of sleeve, the other end of sleeve is provided with some tapped through holes that circumferentially distribute along sleeve outer surface, is provided with set screw in tapped through hole.Because being cut apart some pieces of rear formation by notch in the end of sleeve, adjust the set screw on sleeve, make sleeve have the end of tapped through hole upwards to lift, the end that sleeve props up piece clamps finder, then select as required set screw adjustment, can easily finder be adjusted to primary telescope and be synchronizeed, regulate easy and convenient quick, direction is clear and definite, and simple in structure.
As preferably, the inner side of described piece end is provided with circular arc projection, makes to adjust set screw more easy and convenient.
As preferably, described tapped through hole has three, circumferentially uniform along sleeve outer surface.
As preferably, the outside that described tapped through hole is positioned at sleeve is provided with pad, and pad and sleeve are one-body molded, prevent the wearing and tearing of set screw to sleeve.
As preferably, described sleeve and the carrier base structure for adopting plastic material to make, the structure of set screw for adopting nylon material to make.The sleeve good springiness that plastic material is made, convenient adjustment, quality is light, and the set screw that nylon material is made is little to sleeve wearing and tearing, long service life.
Main beneficial effect of the present utility model is, can easily finder be adjusted to primary telescope and be synchronizeed, and regulates easy and convenient fast, and direction is clear and definite, and simple in structure, wear and tear little, and long service life.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the cut-open view of Fig. 1.
Fig. 3 is the structural representation of the utility model sleeve.
Embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Figure 1 to Figure 2, astronomical telescope finder bracket, comprise the sleeve 2 that is arranged on finder 1 outer ring and the carrier base 5 that is fixedly connected on sleeve downside, one end of sleeve is provided with 6-8 the notch circumferentially distributing along sleeve outer surface, a rear formation 6-8 piece 6 is cut apart by notch in the end of sleeve, each piece end is provided with the projection of circular arc towards the inner side of sleeve interior surface, the other end of sleeve is provided with 3 along the equally distributed tapped through hole of the same circumference of sleeve outer surface, is provided with set screw 3 in each tapped through hole.The outside that described tapped through hole is positioned at sleeve is provided with circular pad 4, and pad and sleeve are one-body molded.Sleeve and the carrier base structure for adopting plastic material to make, the structure of set screw for adopting nylon material to make.During use, adjust the set screw on sleeve, make sleeve have the end of tapped through hole upwards to lift, the end that sleeve props up piece clamps finder, then select as required set screw adjustment, can easily finder be adjusted to primary telescope and be synchronizeed, regulate easy and convenient quick, direction is clear and definite, and simple in structure.
The above is preferably embodiment of the utility model, not with this, limits practical range of the present utility model.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
