Specific implementation mode
Attached drawing 1-7 is described in detail below the utility model sextant verticality decision maker below.
Embodiment 1
The present embodiment is a kind of sextant verticality judgement mirror for marine sextant, with reference to figure 1, attached drawing mark therein
Note is described as follows：1, auxiliary mirror, 1-1, frame, 1-2, eyeglass, 2, rotating device, 2-1, rotary axle box, 2-3,2-2, shaft turn
Dynamic holder, 3, handle, 4, drum wheel, 5, frame body, 6, telescope, 7, index glass, 8, optical filter, 9, fixed mirror.
A kind of sextant verticality decision maker is fixed on sextant by the frame 1-1 and rotary components 2 of auxiliary mirror 1
On holder 5, whether the axis for being used for intuitive judgment sextant handle 3 when altitude of the heavenly body angle observation is vertical with sensible horizon face；
The auxiliary mirror 1 uses rectangular preceding plated film plane mirror；The frame 1-1 of the auxiliary mirror 1 is installed on shaft 2-2,
And it is parallel to shaft axis, auxiliary mirror 1 is fixed on by 3 torsion springs on frame 1-1, and the back sides frame 1-1 of auxiliary mirror 1 are equipped with
2 positive screws of rule, can be finely adjusted the angle of auxiliary mirror 1, the bottoms frame 1-1 of auxiliary mirror set 3 screw holes, such as Fig. 2 institutes
Show；
The rotary components 2 include shaft 2-2, rotary axle box 2-1 and rotating bracket 2-3, and the rotating bracket 2-3 is fixed
In on the sextant frame body 5；The shaft 2-2 uses brass material, and top is equipped with 3 screw holes, for fixing auxiliary mirror
Frame 1-1, as shown in Figure 3；
The rotary axle box 2-1 uses brass material, and axle sleeve axis is parallel with handle axis, and auxiliary mirror can be around axle sleeve axis
It is rotated, keeps auxiliary mirror parallel with handle axis always in rotary course, auxiliary mirror reflection not Tongfang can be made by rotation
To the sky-line, as shown in Figure 4.
The rotating bracket bottom is equipped with 2 screw holes, perpendicular to sextant frame body Plane Installation in sextant front, such as
