After the locking device that the two can be locked.
The Zoom lens structure of adjustable core as above, it is characterised in that: described locking device is saturating before including being located at
Multiple screw holes 31 in lens group group 1, described rear lens group 2 is provided with the connection that multiple with described screw hole 31 is corresponding
Through hole 32, is equipped with in described connection through hole 32 and can coordinate with screw hole 31 and frontal lens group 1 and rear lens group 2 be locked
It is scheduled on screw 33 together.
The Zoom lens structure of adjustable core as above, it is characterised in that: described screw hole 31 is four, with described
The connection through hole 32 of screw hole 31 correspondence and screw 33 be also four.
The Zoom lens structure of adjustable core as above, it is characterised in that: described frontal lens group 1 is provided with circle
The first counterbore 4 and communicate therewith and rounded the second counterbore 5, the aperture of the first described counterbore 4 is more than the second counterbore 5
Aperture, described rear lens group 2 is provided with the first boss 6 and the second boss 7, the first described boss 6 and the second counterbore 5
Coordinating, the second described boss 7 coordinates with the first counterbore 4.
Compared with prior art, this utility model has the following advantages:
1, frontal lens group of the present utility model and rear lens group are to separate, can be relative both when assembly connection
Rotate, during rotating, i.e. complete aligning, thus have adjusted axiality, by locking device by two after being adjusted to put in place
Person locks, and overcomes the axiality of lens group in zoom high-rate lens and does not reaches the defect of requirement, makes lens construction
Image quality reach optimum state, this utility model effectively improve zoom high magnification image quality and produce yield low
Problem.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, frontal lens group of the present utility model and rear lens group use multiple screws to be connected to fix, in rear lens group
Rotate and during aligning, rear lens group can the most repeatedly rotate, such as be provided with 4 screws in frontal lens group
Hole, therefore, rear lens group can rotate 4 times and aligning when rotating aligning, and the angle every time rotated is 90 degree.General and
Speech, in the chance of these 4 times rotation aligning, the most once can be adjusted to the axiality of frontal lens group with rear lens group
Excellent degree so that the optical axis center of frontal lens group and rear lens group as much as possible with in the optical axis of whole lens construction
The heart overlaps, thus improves image quality, it is ensured that camera lens entirety optical property, and facilitates eyeglass and assemble and be effectively increased
Product quality.
3, this utility model frontal lens group be provided with the first counterbore of circle and communicate therewith and rounded 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, and first
Boss and the second counterbore coordinate, and the second boss and the first counterbore coordinate.Carried out by the version of circular boss with counterbore
Coordinate, it is not necessary to other location structure such as locating dowel and hole, location is set again, the most more convenient in the repairing of mould, during measurement also
More convenient, 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 steady, and the accuracy of aligning is the highest.
4, this utility model simple in construction, easy to assembly, it is suitable for popularization and application.

Fig. 2 is generalized section of the present utility model；
Fig. 3 is the zoomed-in view in Fig. 2 at A.
[detailed description of the invention]
Below in conjunction with the accompanying drawings this utility model is further described:
A kind of Zoom lens structure of adjustable core, including frontal lens group 1 with can relative to frontal lens group 1 rotate rear
Lens group group 2, be provided with between described frontal lens group 1 and rear lens group 2 the two relatively rotate and after aligning can by the two
The locking device of locking.Frontal lens group 1 and rear lens group 2 are to separate, and can relatively rotate both when assembly connection,
During rotating, i.e. complete aligning, thus have adjusted axiality, by locking device, the two is locked after being adjusted to put in place
Fixed, overcome the axiality of lens group in zoom high-rate lens and do not reach the defect of requirement, make the one-tenth of lens construction
Picture element amount reaches optimum state, and this utility model 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
Described locking device includes the multiple screw holes 31 being located in frontal lens group 1, in described rear lens group 2
Being provided with the connection through hole 32 that multiple with described screw hole 31 is corresponding, being equipped with in described connection through hole 32 can be with screw hole 31
The screw 33 coordinated and frontal lens group 1 and rear lens group 2 are locked together.Frontal lens group 1 adopts with rear lens group 2
Connect fixing with multiple screws 33, therefore, rotate and during aligning, rear lens group 2 can order in rear lens group 2
Ground repeatedly rotates, such as be provided with 4 screw holes 31 in frontal lens group 1, and therefore, rear lens group 2 can when rotating aligning
To rotate 4 times and aligning, the angle every time rotated is 90 degree.It is said that in general, in the chance of these 4 times rotation aligning, always have one
Secondary the axiality of frontal lens group 1 with rear lens group 2 can be adjusted to excellent degree so that frontal lens group 1 and after
The optical axis center of lens group 2 optical axis center with whole lens construction as much as possible overlaps, thus improves image quality, it is ensured that
Camera lens entirety optical property, and facilitate eyeglass and assemble and be effectively increased product quality.
Described frontal lens group 1 is provided with the first counterbore 4 of circle 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, and described rear lens group 2 is provided with the first boss 6 He
Second boss 7, the first described boss 6 coordinates with the second counterbore 5, and the second described boss 7 coordinates with the first counterbore 4.Pass through
Circular boss coordinates with the version of counterbore, it is not necessary to arrange other location structure such as locating dowel and hole, location again,
In the repairing of mould the most more convenient, the most more convenient during measurement, only need to ensure the axiality that the mirror cell that each eyeglass coordinates justifies
?.And the first boss 6 coordinates with the second counterbore 5, the second boss 7 coordinates with the first counterbore 4, have employed double polarizing keys heavy with double
The fit structure in hole so that rear lens group 2 relatively rotates more steady, and the accuracy of aligning is the highest.
