Embodiment
Reaching by reference to the accompanying drawings embodiment is illustrated optical filter pitching regulating device structure of the present invention.
Optical filter pitching regulating device of the present invention, this device includes regulates part and optical filtering part, described adjusting portion is divided and is included driving lever 1, adjusting bracket 2, adjusting knob 3 supports 4, described adjusting knob 3 connects by the threaded hole of adjusting bracket 2, adjusting bracket 2 one sides are connected with scale dish 8, driving lever 1 and swivel mount 9 are threaded connection and pass through the rail groove of support 4 upper ends, top at driving lever 1 is provided with pointer 7 by screw, threaded hole lower springs hole at adjusting bracket 2, spring eye is equipped with an end of spring 12, and the other end of spring 12 movably withstands in the hole of driving lever 1.
Described filter unit is divided and is included support 4, fix two turning axles 5 at the central axis of circular holes two ends of support 4, the turning axle 5 of take is fixed with the swivel mount 9 around turning axle 5 rotation as back shaft, be fixed with filter holder 10 in swivel mount 9, optical filter is fixed in filter holder 10 threadably by trim ring 11, be provided with a groove in the lower end of support 4, orienting lug 6 is housed in groove, make the optical filter can single direction rotation.
The surface of described index dial 8 is semicircular arc, and the center of circle of semicircular arc is concentric with the axle core of described turning axle 5.Described support 4 is connected with the upper end rectangular shape for the lower end semi-circular shape, and the width of rectangular shape is greater than the diameter of semi-circular shape.
Optical filter pitching regulating device of the present invention, by the main body rack 4 of optical filter, is grouped together other functional parts; The horizontal diameter of the axle core of turning axle 5 and optical filter and filter holder 10 point-blank, is fixed on the diameter axis that support 4 lower end circular holes are vertical with upper plane; And the vertical center axis of driving lever 1 is overlapped with the vertical center axis of support 4, guarantee pointer 7 and optical filter synchronizing moving, adjusting knob 3 be by with support 4 on threaded adjusting, make driving lever 1 drive filter holder 10 and take turning axle axle core as axle rotates, can read the angle that optical filter rotates by pointer 7 and index dial 8 simultaneously.
