The locking device of the two locking.
Varifocus lens device as above, it is characterised in that: described locking device includes being located in frontal lens group 1
Multiple screw holes 31, described rear lens group 2 is provided with the connection through hole 32 that multiple with described screw hole 31 is corresponding, institute
It is equipped with in the connection through hole 32 stated and can coordinate with screw hole 31 and frontal lens group 1 and rear lens group 2 are locked together
Screw 33.
Varifocus lens device as above, it is characterised in that: described screw hole 31 is four, with described screw hole
The connection through hole 32 of 31 correspondences and screw 33 are also four.
Varifocus lens device as above, it is characterised in that: described frontal lens group 1 is provided with circular first and sinks
Hole 4 and the second that communicate therewith and rounded counterbore 5, the aperture of the first described counterbore 4 is more than the aperture of the second counterbore 5,
Described rear lens group 2 is provided with the first boss 6 and the second boss 7, and the first described boss 6 coordinates with the second counterbore 5, institute
The second boss 7 stated coordinates with the first counterbore 4.
Compared with prior art, the present invention has the following advantages:
1, frontal lens group and the rear lens group of the present invention is to separate, and can relatively turn both when assembly connection
Dynamic, during rotating, i.e. complete aligning, thus have adjusted axiality, after being adjusted to put in place, incite somebody to action the two by locking device
Lock, overcome the axiality of lens group in zoom high-rate lens and do not reach the defect of requirement, make lens construction
Image quality reaches optimum state, and the present invention effectively improves zoom high magnification image quality and produces low the asking of yield
Topic.It is applicable to security protection, number etc. and needs to be made up of multiple groups the camera lens product of optical system.
2, the frontal lens group of the present invention and rear lens group to use multiple screws to be connected fixing, in the rotation of rear lens group
And during aligning, rear lens group can the most repeatedly rotate, such as in frontal lens group, it is provided with 4 screw holes,
Therefore, rear lens group can rotate 4 times and aligning when rotating aligning, and the angle every time rotated is 90 degree.It is said that in general,
Rotate in the chance of aligning, the most once can frontal lens group is adjusted to excellent with the axiality of rear lens group for these 4 times
Degree so that the optical axis center of frontal lens group and rear lens group as much as possible with the optical axis center weight of whole lens construction
Close, thus improve image quality, it is ensured that camera lens entirety optical property, and facilitate eyeglass and assemble and be effectively increased product
Quality.
3, frontal lens group of the present invention is provided with the first counterbore of circle and communicate therewith and rounded the second counterbore,
The aperture of the first counterbore is more than the aperture of the second counterbore, and rear lens group is provided with the first boss and the second boss, the first boss
Coordinating with the second counterbore, the second boss and the first counterbore coordinate.Coordinated with the version of counterbore by circular boss,
Without arranging other location structure such as locating dowel and hole, location again, the most more convenient in the repairing of mould, also compare during measurement
Convenience, only need to ensure the axiality that the mirror cell that each eyeglass coordinates justifies.And the first boss and the second counterbore coordinate, second
Boss and the first counterbore coordinate, and have employed the fit structure of double polarizing keys and double counterbores so that rear lens group relatively rotates more flat
Surely, and the accuracy of aligning is the highest.
4, present configuration is simple, easy to assembly, is suitable for popularization and application.
