Abstract
The utility model discloses an anti-deformation installation device for a primary mirror of a reflecting telescope. The anti-deformation installation device comprises a base plate fixed connected with a lens cone, a plurality of upright columns, a plurality of block pieces and a plurality of bolts, wherein the plurality of the upright columns are uniformly arranged at the edges of the base plate, the primary mirror is arranged at the middle of the plurality of the upright columns, the plurality of the block pieces are correspondingly installed at the top ends of the upright columns respectively, the inner ends of the block pieces exceed the inner side surfaces of the upright columns and can block the primary mirror, the plurality of the bolts are uniformly installed at the edges of the base plate respectively, the front end of threaded rods of the bolts penetrate through the base plate and are contacted with the primary mirror. As the periphery of the primary mirror is limited by the upright columns, the inner side is limited by the block pieces, the outer side is limited by the bolts, and the bolts are installed on the base plate, thereby being capable of adjusting the position of the top part of the threaded rod relative to the base plate, and realizing fine adjustment of the angle of the primary mirror. The overall installation device does not form compulsory pressure for the primary mirror, so that the pressure born by the primary mirror is small, thereby being capable of preventing the primary mirror from deforming, and prolonging the service life of the primary mirror.
Description
Technical field
The utility model relates to a kind of autocollimator, relates in particular to a kind of anti-deformation erecting device of autocollimator primary mirror.
Background technology
The principle of work of autocollimator is different with refractor, its light that utilizes a recessed parabolic mirror (being primary mirror) will enter camera lens converges back reflection to a level crossing (being secondary mirror) that is positioned at the lens barrel front end, and then by this level crossing light is reflexed in the outer eyepiece of lens barrel, we just can observe the image of starry sky like this.Existing autocollimator, its primary mirror is installed on the interior base plate of lens barrel, in order to regulate the angle of (fine setting) primary mirror, at primary mirror screw rod is installed usually, the other end of screw rod passes base plate and is connected with nut, and spring housing is loaded on the screw rod and between base plate and primary mirror installing plate.The defective of this structure is: spring keeps a lasting local pressure to primary mirror, and this pressure may make the primary mirror distortion until breaking, and has shortened the life-span of primary mirror; In addition, screw rod directly contacts with primary mirror, also has the problem that scratches primary mirror or primary mirror is broken.
The utility model content
The purpose of this utility model just is to provide in order to address the above problem a kind of anti-deformation erecting device of autocollimator primary mirror, and this device does not produce pressure to primary mirror, so can prevent the primary mirror distortion and break the life-span of prolongation primary mirror.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The anti-deformation erecting device of autocollimator primary mirror described in the utility model comprises the base plate of fixedlying connected with lens barrel, column, catch and bolt, described column is a plurality of, evenly be arranged at the edge of described base plate respectively, described primary mirror places the centre of a plurality of described columns, described catch is a plurality of, correspondence is installed on the top of described column respectively, the inner of described catch exceeds the medial surface of described column and can block described primary mirror, described bolt is a plurality of, evenly be installed on the edge of described base plate respectively, the screw front end of described bolt passes described base plate and contacts with described primary mirror.
As preferably, the quantity of described column, described catch and described bolt is three.
The screw front end of described bolt is provided with rubber, can avoid primary mirror to be scratched by screw rod.
The beneficial effects of the utility model are:
Because it is spacing by column around the primary mirror, inboard spacing by catch, the outside is spacing by bolt, bolt is installed on base plate, can regulate its screw rod top with respect to the position of base plate, realizes the angle fine setting of primary mirror, the whole erection device does not all form enforceable pressure to primary mirror, so the primary mirror pressure is little, can prevent its distortion, prolonged the life-span of primary mirror.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, autocollimator primary mirror described in the utility model comprises lens barrel 1, primary mirror 2, secondary mirror 3, eyepiece 5 and the focusing mount 4 of eyepiece 5 is installed, during application, light is injected by telescopical front end shown in arrow among the figure, project the reflective surface of secondary mirror 3 by primary mirror 2 reflection back break-ins, reflex to eyepiece 5 again, the observer observes the starry sky scene from the top of eyepiece 5.As shown in Figure 2, during practical application, telescopical front end is inclined upwardly, and there is the gravity to the telescope rear end in primary mirror 2, and structure of the present utility model has also been utilized this point, specifically acts on as described below.
As shown in Figure 3 and Figure 4, the anti-deformation erecting device of autocollimator primary mirror described in the utility model comprises the base plate 10 of fixedlying connected with lens barrel 1, column 7, catch 6 and bolt 9, column 7 is three, evenly be arranged at the edge of base plate 10 respectively, primary mirror 2 places the centre of three columns 7, catch 6 is three, correspondence is installed on the top of column 7 respectively, the inner of catch 6 exceeds the medial surface of column 7 and can block primary mirror 2, bolt 9 is three, evenly be installed on the edge of base plate 10 respectively, the screw front end of bolt 9 passes base plate 10 and contacts with primary mirror 2, and the screw front end of bolt 9 is provided with rubber 8.
In conjunction with Fig. 2 and Fig. 3, when using, near the rubber 8 of the screw front end of bolt 9, primary mirror 2 is not subjected to any external pressure to primary mirror 2, and can not influence the reflection to light fully under its gravity effect.By regulating the nut of bolt 9, can change the angle of primary mirror 2, to realize the optimal viewing effect.
