Detailed description of the invention
By reference to the accompanying drawings and embodiment optical filter pitching regulating device structure of the present invention is illustrated.
Optical filter pitching regulating device of the present invention, this device includes and regulates part and optical filtering part, described adjusting portionDivide and include driving lever 1, adjusting bracket 2, adjusting knob 3 supports 4, described adjusting knob 3 connects by the screwed hole of adjusting bracket 2, adjusting bracket 2One side is connected with scale dish 8, and driving lever 1 and swivel mount 9 are threaded connection and pass through the rail groove of support 4 upper ends, at driving lever 1Top is provided with pointer 7 by screw, and in the screwed hole lower springs hole of adjusting bracket 2, spring eye is equipped with one end of spring 12, spring12 the other end movably withstands in the hole of driving lever 1.
Described filter unit is divided and is included support 4; Fix two rotating shafts 5 at the central axis of circular holes two ends of support 4, to rotateThe swivel mount 9 that axle 5 rotates around rotating shaft 5 for back shaft is fixed with is fixed with filter holder 10 in swivel mount 9, and optical filter is logicalCross trim ring 11 and be fixed on threadably in filter holder 10, be provided with a groove in the lower end of support 4, guide pad is housed in groove6, make the optical filter can single direction rotation.
The surface of described scale dish 8 is semicircular arc, and the center of circle of semicircular arc is concentric with the axle core of described rotating shaft 5. InstituteState support 4 and be connected with upper end rectangular shape for lower end semi-circular shape, 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 combined to other functional partsTogether; The horizontal diameter of the axle core of rotating shaft 5 and optical filter and filter holder 10, is fixed on support 4 lower ends point-blankOn the circular hole diameter axis vertical with upper plane; And the vertical center axis of driving lever 1 is overlapped with the vertical center axis of support 4, protectCard pointer 7 and optical filter synchronizing moving, adjusting knob 3 be by with support 4 on threaded adjusting, make driving lever 1 drive filter holder10 rotate taking rotating shaft axle core as axle, can read the angle that optical filter rotates by pointer 7 and scale dish 8 simultaneously.
As Figure 1-4, the structure of optical filter pitching regulating device of the present invention is, filter holder 10 and support 4 cylindersRing structure is concentric, is connected by knob 5, in order being that Stability Analysis of Structures is rotated, knob 5 to be sticked with glue and connects the peace that is fixed on support 4On dress hole; In order to make, optical filter is single to be rotated around rotating shaft 5, and lower end is furnished with guide pad 6; In addition one of structure spring 12 of the present inventionEnd is fixed on support 4, and the other end is slidably connected with driving lever 1, ensures the accurate impatient good mechanical performance of structure; From figureIn 1, can see its overall appearance.
Optical filter pitching regulating device of the present invention, the adjusting of described swivel mount 9 is by twisting adjusting knob 3, drives and dialsBar 1 moves, then rotate by driving lever 1 driven rotary frame 9, in this process, the effect that driving lever 1 is resetted is played in extension spring 12, leadsPlaying to piece 6 is the effect that swivel mount 9 can offset direction while rotating, and pointer 7 moves with driving lever 1, on scale dish 8, drawsCross, can determine accurately the angle that the optical filter on filter holder 10 turns over by original position.
The junction of lower end semi-circular structure and upper end rectangular configuration in support 4, the width of rectangular shape is greater than semicircleThe diameter of shape, thus while facilitating structure to combine use with other structures, play fixing position-limiting action; This device also has pointer 7 and markChi dish 8, can accurately determine the angle that the optical filter in filter holder 10 turns over by original position. Apparatus of the present invention wholeBody profile lower end is semicircular structure, can save space, and range of application is more extensive.
Fix two rotating shafts 5 at the central axis of circular holes two ends of support 4, swivel mount 9 is taking rotating shaft 5 as back shaft, around axleRotation, thus drive the filter holder 10 being fixed in swivel mount 9 to rotate around rotating shaft 5, thus reach the optical filter anglec of rotationObject. The adjusting of swivel mount 9 is by twisting adjusting knob 3, drives driving lever 1 to move, then turns by driving lever 1 driven rotary frame 9Move, in this process, the effect that driving lever 1 is resetted is played in extension spring 12, and it is that swivel mount 9 can not be offset while rotating that guide pad 6 playsThe effect of direction, adjusting knob 3 is threaded with the adjusting bracket 2 being screwed on support 4; Pointer 7 moves with driving lever 1,Scale dish 8 streaks above, can determine accurately the angle that in filter holder 10, optical filter turns over by original position.
By said process, whole device adjustment process is complete.
Fig. 5 is the reference part Local map that coordinates this device overall structure to match, in figure upper end open profile can withDevice perfectly coordinates, and can not rock skew can make this device busy time; Lower ending opening can make this install dismounting easilyUnload; Intermediate thread can be used jackscrew, or hand button etc. is fixing, increases this device stability in use; This is with reference to joining in additionThe two ends of closing parts may be extended to other structures, make this device be suitable for application scope more extensive.
