Abstract
The utility model discloses a convenient regulation type mounting device for a primary mirror of a reflecting telescope. The mounting device comprises a bottom pate, a primary mirror mounting plate, a screw, a nut and a spring which are fixedly connected with a lens barrel, wherein the primary mirror is installed at one side of the primary mirror mounting plate, one end of the screw is installed at the other side of the primary mirror mounting plate, the other end of the screw penetrates through the bottom plate and is connected with the nut, and the spring is sleeved on the screw and located between the bottom plate and the primary mirror mounting plate. The convenient regulation type mounting device enables the screw to be installed on the primary mirror mounting plate directly through additionally arranging the primary mirror mounting plate, and the screw and the spring are not contacted with the primary mirror directly, thereby preventing the primary mirror from being scratched by the screw and the spring and avoiding a problem of cracking caused by scratches, protecting the primary mirror from being scratched and damaged under the premise of not influencing the performance of the primary mirror, and prolonging the service life of the primary mirror.
Description
Technical field
The utility model is related to a kind of autocollimator primary mirror, more particularly to a kind of convenient regulating type erecting device of autocollimator primary mirror.
Background technology
The operation principle of autocollimator is different from refractor, and it utilizes a recessed parabolic mirror（That is primary mirror）By into the light collection back reflection of camera lens to a level crossing positioned at lens barrel front end（That is secondary mirror）On, then light is reflexed in the eyepiece outside lens barrel by this level crossing again, so we just can observe the image of starry sky.Existing autocollimator, its primary mirror is installed on the base plate in lens barrel, in order to adjust（Fine setting）The angle of primary mirror, is generally provided with screw rod on primary mirror, and the other end of screw rod is connected through base plate with nut, and spring housing is loaded on screw rod and positioned between base plate and primary mirror installing plate.The defect of this structure is：Spring keeps a lasting local pressure to primary mirror, and the pressure may make primary mirror deformation until rupture, shortens the life-span of primary mirror；In addition, screw rod is directly contacted with primary mirror, there is also scratch primary mirror or make the problem of primary mirror ruptures.
Utility model content
The purpose of this utility model, which is that, provide a kind of convenient regulating type erecting device of autocollimator primary mirror to solve the above problems, and this device does not produce direct local pressure to primary mirror, so can prevent that primary mirror is scratched and destroyed, extends the life-span of primary mirror.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The convenient regulating type erecting device of autocollimator primary mirror described in the utility model includes base plate, primary mirror installing plate, screw rod, nut and the spring being fixedly connected with the lens cone, the primary mirror is installed on the side of the primary mirror installing plate, one end of the screw rod is installed on the opposite side of primary mirror installing plate, the other end of the screw rod is connected after passing through the base plate with the nut, and the spring housing is loaded on the screw rod and positioned between the base plate and the primary mirror installing plate.
Preferably, being connected between the primary mirror installing plate and the primary mirror by annular edge cover strip.
The primary mirror installing plate is plastic plate or plank.
The beneficial effects of the utility model are：
The utility model is by increasing primary mirror installing plate; screw rod is set to be directly mounted on primary mirror installing plate; screw rod and spring are not directly contacted with primary mirror; splintering problem caused by avoiding screw rod and spring to the scuffing of primary mirror and therefore; protect primary mirror not to be scratched and destroy on the premise of primary mirror performance is not influenceed, extend the life-span of primary mirror.
Brief description of the drawings
Fig. 1 is the main structure diagram of autocollimator primary mirror described in the utility model；
Fig. 2 is the application state figure of autocollimator primary mirror described in the utility model；
Fig. 3 is the front view of the convenient regulating type erecting device of autocollimator primary mirror described in the utility model；

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, autocollimator primary mirror described in the utility model includes lens barrel 1, primary mirror 2, secondary mirror 3, eyepiece 5 and the focusing mount 4 for installing eyepiece 5, using when, light is injected by the front end of telescope as shown by arrows in FIG., deflecting projects the reflective surface of secondary mirror 3 after being reflected by primary mirror 2, eyepiece 5 is re-reflected into, observer observes starry sky scene from the top of eyepiece 5.
As shown in Figure 3 and Figure 4, the convenient regulating type erecting device of autocollimator primary mirror described in the utility model includes base plate 11, primary mirror installing plate 7, screw rod 9, nut 10 and the spring 8 being fixedly connected with lens barrel 1, primary mirror 2 is installed on the side of primary mirror installing plate 7, is connected between primary mirror installing plate 7 and primary mirror 2 by annular edge cover strip 6（This structure is common binding structure）, one end of screw rod 9 is installed on the opposite side of primary mirror installing plate 7, and the other end of screw rod 9 is connected after passing through base plate 11 with nut 10, and spring 8 is set on screw rod 9 and positioned between base plate 11 and primary mirror installing plate 7, the inner side of nut 10 is additionally provided with packing ring 12.According to needs are applied, primary mirror installing plate 7 is plastic plate or plank.
With reference to Fig. 2 and Fig. 3, in use, the front end of telescope is inclined upwardly, the angle of primary mirror 2 is adjusted if desired, then the different nut 10 of turn, under the drive of screw rod 9, primary mirror installing plate 7 drives primary mirror 2 to move, and reaches the purpose for changing angle.
