Description
Technical field
The utility model relates to physics classes, for the Liar that infrared applications specially design, espespecially a kind of double vision field lens
Head zoom focusing driving mechanism.
Background technique
In the use process of camera lens, it usually needs it is adjusted focal length to obtain good visual angle or clearly image,
The lens focusing of the prior art is linked by guide pin, is in simple terms exactly to be equipped with guide pin on focusing drum, is processed on lens barrel
There is helicla flute, guide pin and helicla flute, which are formed, to be cooperated, and drives guide pin that the rotation of handwheel is become focusing drum by the straight trough on handwheel
Linear motion, such focus adjusting mechanism be the prior art use common focusing patterns, this is that most of architects examine
The problem of worry, and the entire main operation mode of industry, but can focus again zoom when obtain different visual fields,
This problem was not suggested always.
Summary of the invention
The purpose of this utility model is to provide a kind of double-view field camera lens zoom focusing driving mechanisms, increase the length of helicla flute
Degree, increases the running length of focusing drum, has obtained two different visual fields, monoscopic can only be realized by solving infrared focusing lens
The problem of.
In order to achieve the above purposes, the technical solution adopted by the utility model is:
A kind of double-view field camera lens zoom focusing driving mechanism, including camera lens, lens barrel, focusing drum, guide pin, it is characterised in that:
It is provided with lens barrel outside camera lens middle section, three sections of helicla flutes are provided on lens barrel, rack gear, camera lens upper right end is arranged in lens barrel right part
It is provided with motor, motor right part is provided with gear, and gear and gear ring, which are formed, to be cooperated, and lens barrel is internally provided with focusing drum, focusing drum
On be provided with guide pin, guide pin is arranged in helicla flute and can move along helicla flute, and helicla flute lower part is 25 ° of visual fields, on helicla flute
Portion is 100 ° of visual fields.
The beneficial effects of the utility model embody a concentrated reflection of, by reasonably designing and increasing spiral slot length, in spiral shell
25 ° of visual field is realized in spin slot bottom, and rotates to helicla flute top in focusing drum and realize 100 ° of visual fields, reaches at same one
Two visual fields are combined in infrared lens, reach more convenient and fast observing effect.
Detailed description of the invention

Apply example, based on the embodiments of the present invention, those of ordinary skill in the art without making creative work, institute
The every other embodiment obtained, belongs to scope of protection of the utility model.
A kind of double-view field camera lens zoom focusing driving mechanism, including camera lens 1, lens barrel 2, focusing drum 7, guide pin 3, feature exists
In: it is provided with lens barrel 2 outside 1 middle section of camera lens, three sections of helicla flutes 8 are provided on lens barrel 2, rack gear 4, mirror is arranged in 2 right part of lens barrel
First 1 upper right end is provided with motor 6, and 6 right part of motor is provided with gear 5, and gear 5 and gear ring 4, which are formed, to be cooperated, and sets inside lens barrel 2
It is equipped with focusing drum 7, guide pin 3 is provided on focusing drum 7, guide pin 3 is arranged in helicla flute 8 and can move along helicla flute 8, helicla flute
8 lower parts are 25 ° of visual fields, and 8 top of helicla flute is 100 ° of visual fields, by reasonably designing and increasing spiral slot length, in spiral
Trench bottom realizes 25 ° of visual field, and rotates to helicla flute top in focusing drum and realize 100 ° of visual fields, reaches red at same one
Two visual fields are combined in outer camera lens, reach more convenient and fast observing effect.
