Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of periscopic optics proposed
Zoom lens mould group.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of periscopic Zoom optic lens mould group, including lens barrel, the lens barrel is L-shaped, the both ends inner wall difference of lens barrel
It is connected with supplementary lens group and postposition lens group, and lens barrel is connected with photosensitive element close to one end of postposition lens group, lens barrel
Right angle inner wall is connected with the prism group being obliquely installed, and the horizontal segment inner wall of lens barrel is connected with outer ring lens group, outer ring lens group
Inner ring is equipped with inner ring lens group, and inner ring lens group and outer ring lens group pass through regulating device adjustable range.
Preferably, the regulating device includes the external inflator for being connected to lens barrel outer wall, and the threaded one end of external inflator connects
Be connected to adjusting screw rod, and adjusting screw rod is located at one end in external inflator and is rotatably connected to piston, the outer ring lens group it is interior
Circle is equipped with sliding slot, is equipped with link block in sliding slot, the two sides of link block pass through two inner walls of spring and miniature air bag and sliding slot respectively
Connection, the link block are connected to the outer ring of inner ring lens group, and miniature air bag is connected to external inflator by gas-guide tube.
Preferably, the key light overlapping of axles of the supplementary lens group and postposition lens group.
Preferably, the key light overlapping of axles between the outer ring lens group, inner ring lens group and postposition lens group, and its key light
Axis is overlapped with the center line of photosensitive element.
Compared with prior art, the utility model has the beneficial effects that the utility model structure is simple, rotation adjusts spiral shell
Bar, band piston are moved to the left, and compress external inflator, provide gas-guide tube air guide into miniature air bag, and miniature air bag expansion reduces
The distance between outer ring lens group and inner ring lens group adjust image-forming range, adjusting screw rod are rotated backward, in recoil of spring masterpiece
Under, it is possible to increase distance between outer ring lens group and inner ring lens group, thus realize that tuning up for spacing is turned down, it is different to be applicable in
Photography environment, and adjusting is also extremely convenient.
Detailed description of the invention
Fig. 1 be the utility model proposes structural schematic diagram.
In figure: supplementary lens group 1, regulating device 3, miniature air bag 301, external inflator 302, piston 303, is adjusted lens barrel 2
Screw rod 304, photosensitive element 4, prism group 5, outer ring lens group 6, inner ring lens group 7, postposition lens group 8.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, a kind of periscopic Zoom optic lens mould group, including lens barrel 2, lens barrel 2 is L-shaped, in the both ends of lens barrel 2
Wall is connected separately with supplementary lens group 1 and postposition lens group 8, and lens barrel 2 is connected with photosensitive member close to one end of postposition lens group 8
Part 4, the right angle inner wall of lens barrel 2 are connected with the prism group 5 being obliquely installed, and the horizontal segment inner wall of lens barrel 2 is connected with outer ring lens group
6, the inner ring of outer ring lens group 6 is equipped with inner ring lens group 7, inner ring lens group 7 and outer ring lens group 6 and is adjusted by regulating device 3
Distance.
Regulating device 3 includes the external inflator 302 for being connected to 2 outer wall of lens barrel, and the threaded one end of external inflator 302 is connected with
Adjusting screw rod 304, and one end that adjusting screw rod 304 is located in external inflator 302 is rotatably connected to piston 303, outer ring lens group 6
Inner ring be equipped with sliding slot, be equipped with link block in sliding slot, the two sides of link block pass through spring and miniature air bag 301 and sliding slot respectively
The connection of two inner walls, link block are connected to the outer ring of inner ring lens group 7, miniature air bag 301 and external inflator 302 and are connected by gas-guide tube
It is logical, by adjusting the distance between outer ring lens group 6 and inner ring lens group 7, change imaging focal length.
The key light overlapping of axles of supplementary lens group 1 and postposition lens group 8, outer ring lens group 6, inner ring lens group 7 and postposition are saturating
Key light overlapping of axles between microscope group 8, and its primary optical axis is overlapped with the center line of photosensitive element 4, convenient for imaging.
