Abstract
The utility model discloses a refracting telescope, comprising a lens hood, a focusing component and a cylinder arranged between the lens hood and the focusing component. The focusing component comprises a focusing seat, and is characterized in that one end of the focusing seat is sleeved with a focusing seat ferrule and a locking ring, and the locking ring is sleeved on the focusing seat ferrule in a freely rotatable manner. An object lens frame provided with a lens is arranged in the lens hood, and the object lens frame is connected to the cylinder through an object lens connecting frame. In such a way, a user can adjust the equipment at any degree, so that great convenience in use is provided. In addition, the object lens frame provided with the lens is connected to the object lens connecting frame and a mechanical optical axis can be adjusted, a lens can be rotated through an opening in the object lens frame and can be adjusted through a threaded hole, and micro deviation can be adjusted in a processing procedure, so that good pictures of celestial objects can be obtained.
Description
Technical field
The utility model relates to a kind of refractor that is applied in the optical system.
Background technology
Needing to arrange refractor in the optical system of the compositions such as astronomical telescope focuses in order to see celestial body clearly.Existing refractor generally comprise light shield, focusing component and be installed on light shield and focusing component between cylindrical shell.Yet existing focusing component can not rotate freely, and can not adapt to the user at arbitrarily angled use focusing handwheel, eyepiece and camera, thereby has brought great inconvenience for the user when the equipment of adjustment angle; In addition, be fixed between existing light shield and the cylindrical shell, thereby the length of whole refractor is changeless, so convenient, flexible not in the use.And, the at present bad adjusting of optical axis of refractor, for the In level, asterism and edge star in the middle of the picture that the celestial body photo that obtain must camera CCD imaging are ordered the same, this just need optics optical axis and mechanical optical axis be will same axis on.
Summary of the invention
The purpose of this utility model is to propose a kind of refractor easy to use.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme: a kind of refractor, comprise light shield, focusing component and be installed in described light shield and described focusing component between cylindrical shell, described focusing component comprises focusing mount, it is characterized in that: an end of described focusing mount is arranged with focusing mount lasso and clamp ring, and described clamp ring is set on the described focusing mount lasso free to rotately.
In addition, the utility model also comprises following attached technical scheme:
Described clamp ring is provided with the tight screw of the first system.
The other end of described focusing mount is arranged with rotary sleeve, and described rotary sleeve can rotate freely with respect to described focusing mount.
Described rotary sleeve is provided with the tight screw of the second system.
Described light shield telescopically is set on the described cylindrical shell.
Described light shield is provided with the tight screw of the 3rd system.
Be provided with in described light shield lensed objective lens frame is installed, described objective lens frame is connected on the cylindrical shell by the object lens connection box.
The surface of described objective lens frame is provided with perforate, can rotate lens by described perforate.
Also be provided with threaded hole on the surface of described objective lens frame, in the described threaded hole set screw be installed.
Compared with prior art, the utility model has the advantage of: the clamp ring of freely rotating and rotary sleeve that the place, two ends by focusing mount arranges can adapt to the arbitrarily angled adjustment equipment of user, for use provides great convenience.In addition, fill lensed objective lens frame and be connected on the object lens connection box capable of regulating machinery optical axis, the perforate on the objective lens frame can be rotated eyeglass and threaded hole can be regulated eyeglass, is adjusted at the little deviation in the process, thus the celestial body photo that can obtain.
Description of drawings
Fig. 1 is the plan view corresponding to the refractor of the utility model preferred embodiment.
Fig. 2 is the cut-open view of A-A line in Fig. 1.
Fig. 3 is the planimetric map after the light shield among Fig. 1 removes.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the technical solution of the utility model is elaborated.
Referring to figs. 1 through Fig. 3, a kind of refractor comprises light shield 1, focusing component 3 and is installed in cylindrical shell 5 between described light shield 1 and the described focusing component 3.
Above-mentioned focusing component 3 comprises focusing mount 31, and an end of described focusing mount 31 is arranged with focusing mount lasso 33 and clamp ring 35, and described clamp ring 35 is set on the described focusing mount lasso 33 free to rotately.In addition, in clamp ring 35, also be provided with focusing handwheel 37; And the other end of described focusing mount 31 is arranged with rotary sleeve 39, and described rotary sleeve 39 can rotate freely with respect to described focusing mount 31 equally.As seen, the clamp ring of freely rotating 35 and rotary sleeve 39 that place, focusing mount 31 two ends arranges can adapt to the arbitrarily angled use focusing handwheel 37 of user, eyepiece 38 and camera (not shown), and the angle of adjusting equipment to the user provides great convenience.
In addition, described clamp ring 35 is provided with that the first system tight screw 32, described rotary sleeve 39 is provided with the second tight screw 34 of system and described light shield 1 is provided with the tight screw 12 of the 3rd system.Like this, when being adjusted to correct position, clamp ring 35, rotary sleeve 39 or light shield 1 can be fixed it by the tight screw 32 of the system that goes up separately, 34 or 12.
It is to be noted; above-mentioned preferred embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
