Description
Technical field
The utility model is related to optical field, specially a kind of adjustable camera lens.
Background technology
Optical lens is requisite part in NI Vision Builder for Automated Inspection, directly affects the quality of image quality, and impact is calculated
The realization of method and effect, optical lens can be divided into short-focus lens, middle zoom lens, telephoto lens from focal length；From visual field, size is divided
There are wide-angle, standard, long shot；Dividing in structure has fixed aperture tight shot, manual iris tight shot, and auto iris focuses
Camera lens, manual zoom camera lens, automatic zoom camera lens, auto iris motorized zoom lenses, electronic three variable (aperture, focal length, focusing
All variable) camera lens etc..Wherein convex lens are to be made according to the refraction principle of light.Convex lens are that central authorities are thicker, and edge is relatively thin
Lens, convex lens are divided into the forms such as biconvex, plano-convex and concavo-convex (or positive falcate), convex lens play the role of to assemble light thus also known as
Convergent lens, thicker convex lens such as are then looked in the distance, assemble at the effect, and this is relevant with the thickness of lens, and spectacles for long sight are convex lens,
Conventional lenses are all so that the focal length of camera lens is changed by the threaded adjusting lens on knob camera lens and the distance between lens, its
The camera lens bulky screwing, increased the volume of camera, makes camera carry inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of adjustable camera lens, to solve to carry in above-mentioned background technology
The problem going out.
For achieving the above object, the utility model provides a kind of following technical scheme: adjustable camera lens, including
Knob fixed plate, is provided with internal thread at the fixing hole of described knob fixed plate, the outer surface of threaded rod is provided with external screw thread, described rotation
The internal thread of button fixed plate passes through external screw thread connection screw thread bar corresponding thereto, and the top of described threaded rod is provided with knob, described
The bottom of threaded rod is provided with baffle plate, and the bottom of described baffle plate is provided with connecting rod, and described connecting rod extends into the inner chamber of ram pot, institute
State and between baffle plate and ram pot, accompany spring, the end of described connecting rod is provided with piston, described piston be slidably connected at hydraulic pressure
The inner chamber of cylinder, described ram pot is fixed on lens holder, and the end of described ram pot connects transparent gasbag, described transparent
Inside air bag is provided with retainer ring.
Preferably, the side wall of described knob is provided with anti-slip veins.
Preferably, the upper surface of described knob is provided with pointer, and the surrounding of described knob is provided with scale.
Preferably, the section of described transparent gasbag is concave or convex shape.
Compared with prior art, the beneficial effects of the utility model are: a kind of adjustable camera lens, by work
Transparency liquid in ram pot can be pressed into or extract the transparent gasbag of lenticular lens type out by the regulation of plug, be that transparent gasbag becomes
Shape, makes convex lens deform, thus changing focal length, substituted for traditional screw-on camera lens and saved camera lens screwing body used
Long-pending.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure: 1 transparent gasbag, 2 retainer ring, 3 ram pots, 4 lens holders, 5 pistons, 6 connecting rods, 7 springs, 8 baffle plates,
9 threaded rods, 10 knob fixed plates, 11 internal threads, 12 knobs, 13 anti-slip veins, 14 scales, 15 pointers and 16 external screw threads.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of a kind of technical scheme: adjustable camera lens, including knob
Fixed plate 10, the outer surface of threaded rod 9 is provided with external screw thread 16, is provided with internal thread 11 at the fixing hole of described knob fixed plate 10,
The internal thread 11 of described knob fixed plate 10 passes through external screw thread 16 connection screw thread bar 9 corresponding thereto, the top of described threaded rod 9
It is provided with knob 12, the bottom of described threaded rod 9 is provided with baffle plate 8, for fixing spring 7, the bottom of described baffle plate 8 is provided with connecting rod
6, described connecting rod 6 extends into the inner chamber of ram pot 3, accompanies spring 7 between described baffle plate 8 and ram pot 3, and convex lens can be made multiple
Position, the end of described connecting rod 6 is provided with piston 5, the inner chamber being slidably connected at ram pot 3 of described piston 5, described ram pot 3
It is fixed on lens holder 4, the end of described ram pot 3 connects transparent gasbag 1, is provided with fixation inside described transparent gasbag 1
Ring 2, for fixation balloon shape.
Specifically, the side wall of described knob 12 is provided with anti-slip veins 13, facilitates knob 12 to rotate.
