Description
Technical field
The present invention has longer bushing about a kind of optical facilities, in particular to a kind of group's frame of carrying lens
And bushing overlaps the optical facilities of setting each other.
Background technology
In known optical lens, each group's frame by the guiding of main shaft and along the main axle moving, with generate zoom with
The effect of focusing.
Referring to Fig. 1, it indicates the combination of each the group's frame and main shaft in known optical facilities.Optical facilities 10 have base
The 12, first main shaft 14 of seat, the second main shaft 16,18, first groups of frames 13 of countershaft and second group of frame 15.First main shaft 14, second is led
Axis 16 and countershaft 18 are set on pedestal 12, and the first group of frame 13 carry the first lens group (not shown), the second group of carryings of frame 15 the
Two lens groups (not shown), the first group of frame 13 can be moved by the guiding of the first main shaft 14 and countershaft 18, similarly, second group
Frame 15 can be moved by the guiding of the second main shaft 16 and countershaft 18.In above-mentioned construction, because distinct group frame is configured with each
From main shaft, opposite coaxial precision is bad between group's frame, especially during group is vertical, since different group's frames is assembled to difference
Main shaft and component otherness itself, directly influence the depth of parallelism and position degree between group frame so that opposite between group's frame
Coaxial precision is bad, and affects optical property quality.
Fig. 2,3 are please referred to, indicate the combination of each the group's frame and main shaft in another known optical facilities.Optical facilities 20
With pedestal 22, main shaft 24,26, first groups of frames 23 of countershaft and second group of frame 25.Main shaft 24 is set to pedestal 22 with countershaft 26
On, first group of frame 23 carries the first lens group (not shown), and second group of frame 25 carries the second lens group (not shown), first group of frame
23 move with second group of frame 25 by the guiding of main shaft 24 and countershaft 26.As shown in figure 3, the bushing 27 of first group of frame 23 and master
There must be gap 29 to be moved on main shaft 24 in order to first group of frame 23 between axis 24, if gap 29 is too small or gapless feelings
Under condition, first group of frame 23 is not easy even move on main shaft 24.It is identical in gap size, the length of bushing compared with
Length can be to avoid gap there are caused beat, in construction shown in Fig. 2, since first group of frame 23 and second group of frame 25 are total
Enjoy same main shaft 24, opposite coaxial precision is good between group's frame, if but the length of bushing is shorter, the stability of each group's frame is had
It influences, therefore, it is desirable to the bushing Design of length of group's frame at longer, but the longer bushing of length is easy the row of each group's frame of influence again
Journey.
