Abstract

The utility model relates to a Fourier camera lens, it includes picture frame 8, lens 7, and inner chamber 3 of picture frame 8 is the stairstepping, and each ladder in situ of stairstepping inner chamber 3 is arranged respectively in to lens 7. The utility model provides a Fourier camera lens that exists among the background art easily produce stress strain, the unstable and poor technical problem of camera lens reliability of image quality.

Description

The Fourier camera lens
One, technical field
The utility model relates to a kind of Fourier camera lens.
Two, background technology
There is following shortcoming usually in present Fourier camera lens:
1, easily produces ess-strain, the picture element instability.Common Fourier eyeglass compactness, after each sheet, group were inserted lens barrel, spacer ring placed between each eyeglass, can make eyeglass produce stress.Trim ring directly is pressed on the logical light face edge of glass simultaneously, makes the contact position produce local stress, causes glass deformation poor, finally causes the picture element variation.
2, camera lens poor reliability.There is the gap between present Fourier camera lens spacer ring, glass and the lens barrel, under certain vibrations condition, can be loosening between mirror, eyeglass can produce error at interval, and whole camera lens poor reliability descends system index.
Three, utility model content
The utility model has solved the technical matters that the Fourier camera lens that exists in the background technology easily produces ess-strain, picture element instability and camera lens poor reliability.
Technical solution of the present utility model is: the utility model comprises picture frame 8, eyeglass 7, and its special character is: the inner chamber 3 of described picture frame 8 is stepped appearance, and eyeglass 7 places respectively in each flight of stepped appearance inner chamber 3.
Mounting platform 1 in Di Yanchu in each flight of above-mentioned stepped appearance inner chamber 3 is provided with.
Above-mentioned eyeglass 7 is arranged in the independent interior picture frame 5, and independent interior picture frame 5 is arranged in each flight of stepped appearance inner chamber 3.
Be provided with between the flight upper edge in the above-mentioned independence in picture frame 5 and the stepped appearance inner chamber 3 to repair and cut pad 4 and outer mounting platform 2, and be provided with outer trim ring 6 between the flight lower edge.
Trim ring 10 in above-mentioned eyeglass 7 and independent interior 5 on picture frame are provided with.
Trim ring 10 is pressed on the eyeglass 7 by flexible member 9 in above-mentioned.
The utility model adopts staged trim ring structure that eyeglass rationally is fixed, and every (group) eyeglass can independently be debug, and makes the adjustment of eyeglass more flexible, therefore, it has improved system's right alignment and picture element, and can guarantee that precision index is constant behind the special jerk of experience.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, embodiment
Referring to Fig. 1, the utility model mainly by eyeglass 7, picture frame 8, interior trim ring 10, repair cut pad 4, independent in picture frame 5, outer trim ring 6 and flexible member 9 form.Eyeglass 7 can be divided into monolithic mirror, gummed mirror eyeglass, process the eyeglass mounting platform 1 vertical according to the edge of actual interval situation beyond two effectively logical light faces of outermost of each monolithic mirror, gummed mirror eyeglass with optical axis, with eyeglass 7 one side platforms is that reference for installation is placed on eyeglass 7 in the independent interior picture frame 5, interior trim ring 10 is pressed on the platform of eyeglass 7 opposite sides by flexible member 9, eyeglass 7 is pressed on 5 li on independent interior picture frame, realize the function of axial compression, guarantee simultaneously that when temperature variation is arranged eyeglass 7 also has the snap-in force of appropriateness.At the cylindrical injecting glue of eyeglass 7, realize that eyeglass 7 is in radially flexible fastening.Picture frame 5 designed high-precision separately outer mounting platform 2 and cylindrical is arranged in each was independent, was provided with to repair between independent interior picture frame 5 and the picture frame 8 and cut pad 4, in order to adjust the axially spaced-apart of eyeglass 7 in each independent interior picture frame 5, can do radially between each independent interior picture frame 5 and the picture frame and adjust.And the cylindrical injecting glue of picture frame 5 is fixed each independent picture frame 5 with interior trim ring 10 simultaneously in independent.
