Description
Technical field
The utility model relates to a kind of eyeglass bracing or strutting arrangement, relates in particular to a kind of eyeglass flexible supporting device.
Background technology
Existing lens edge bracing or strutting arrangement is in order to adapt to bigger range of temperature, such as positive and negative one or two hundred degree, usually choose three points on the outer circumference surface of supported optical mirror slip, two some places therein adopt the fixed support pad, adopt spring-loaded radial support at the 3rd some place.This supporting way is when temperature variation, and optical axis moves in a face, can't guarantee that the optical axis of eyeglass overlaps all the time with the central shaft of picture frame.And because Area of bearing is little, the stress of the strong point is bigger, damages eyeglass easily.
Summary of the invention
The purpose of this utility model provides a kind of lens edge flexible supporting device, and it has solved, and existing lens edge bracing or strutting arrangement stress is big, the technical matters of low precision.
Technical solution of the present utility model is:
A kind of lens edge flexible supporting device, comprise picture frame and the fixture that is used for fastening eyeglass, its special character is: described picture frame comprises the annular boss that female cylinder is set and is used for the eyeglass radial location, wherein boss is positioned at an end of cylinder, internal thread is positioned at the other end of cylinder, the annular trim ring that described fixture comprises annular gasket and is threaded with cylinder, described pad is provided with M pad radial slot, M 〉=3 wherein, described pad is divided into M pad claw that stretches to the center of circle by M pad radial slot; Described trim ring with spacers in picture frame, described pad claw and boss respectively from the both sides of eyeglass along eyeglass axial compression eyeglass.
Above-mentioned boss is provided with N boss radial slot, N 〉=3 wherein, described boss is divided into N boss claw that stretches to the center of circle by N boss radial slot, described pad claw and boss claw respectively from the both sides of eyeglass along eyeglass axial compression eyeglass.
One of them parallel with eyeglass on above-mentioned boss side is provided with annular groove.
The radial section of above-mentioned annular groove is rectangle or circular arc.
Above-mentioned M=32, described N=16.
Two parallel with eyeglass on above-mentioned boss sides all are provided with an annular groove, and the annular groove position of ipsilateral does not interlock.
The radial section of above-mentioned annular groove is rectangle or circular arc.
Above-mentioned M=32, described N=16.
Technique effect of the present utility model is:
1, low stress.The utility model provides reliable low stress clamping, avoids when temperature variation is big because supporting construction material and the inconsistent contact stress that causes of lens materials thermal expansivity are excessive.
2, precision height.The utility model device has adopted pad and trim ring, and pad and eyeglass force in pad by trim ring again to contact than large tracts of land, can make eyeglass contact all the time with raised head face, and retainer shaft is to bearing accuracy in big temperature range.Adopt the outer circumference surface of boss claw clipped lens, can make the optical axis of eyeglass overlap all the time, in big temperature range, keep the radial location precision with the central shaft of picture frame.
3, flexible good.After the utility model boss increased annular groove and is divided into a plurality of boss claws by radial slot, radial rigidity and axial rigidity significantly reduced, and have guaranteed good flexibility.
4, compact conformation.

Reference numeral is as follows: 1-picture frame, 2-pad, 3-trim ring, 4-eyeglass, 5-boss claw, 6-boss, 7-annular groove, 11-boss radial slot, 12-pad radial slot, 13-cylinder, 14-pad claw.
Embodiment
The utility model comprises by boss 6 and has picture frame 1, pad 2 that the cylinder 13 of internal thread constitutes, is with externally threaded trim ring 3, picture frame 1 carries out axial elasticity by boss 6 to be supported at eyeglass 4 edges, and threaded trim ring 3 carries out axial compression by 2 pairs of eyeglasses of pad 4.
As improvement of the present utility model, one or two parallel with eyeglass 4 on the boss 6 in the picture frame 1 side is processed with annular groove 7, and referring to Fig. 3 or Fig. 4, the radial section of annular groove 7 can adopt rectangle or circular arc.Also can on boss 6, process boss radial slot 11, make boss 6 be divided into N equal portions (N 〉=3) equably, form N boss claw 5 by boss radial slot 11; Radial location is carried out by N boss claw 5 clampings in the excircle side of supported eyeglass 4; At pad 2 inboard processing pad radial slots 12, the part that pad 2 contacts with eyeglass 4 is divided into M equal portions (M 〉=3) equably by pad radial slot 12, forms M pad claw 14; The edge on a surface of supported eyeglass 4 contacts with the end face of boss 6 and carries out axial location; M pad claw 14 touches with another surperficial side edge of supported eyeglass 4, compresses with the internal thread with externally threaded trim ring 3 precession picture frames 1.
After adopting such structure, the radial rigidity and the axial rigidity of picture frame boss significantly reduce, the flexible increase; Bonding pad and trim ring can keep bearing accuracy in big temperature range, reliable low stress clamping is provided, and avoid when temperature variation is big because supporting construction material and the inconsistent excessive or excesssive gap of contact stress that causes of lens materials thermal expansivity; Compact conformation.
With reference to Fig. 1, radial location and clamping are carried out by boss 6 clampings of picture frame 1 in the excircle side of supported eyeglass 4; The edge on a surface of eyeglass 4 contacts with the end face of boss claw 5, and another surperficial edge of eyeglass 4 contacts with pad claw 14, thereby eyeglass 4 carries out axial location by boss claw 5 and pad claw 14 to it.Opener groove by trim ring 3 outer ends can compress the internal thread of the external thread precession picture frame 1 of trim ring 3 to pad 2.When two sides of the boss 6 on the picture frame 1 all are processed with the staggered annular groove 7 in position, the flexible support better effects if.With reference to Fig. 3 and Fig. 4, the shape in annular groove 7 cross sections can be a rectangle, also can circular arc.
With reference to Fig. 2, boss 6 is divided into 16 equal portions equably by boss radial slot 11, forms 16 boss claws 5.
With reference to Fig. 5, the pad 2 inboard parts that contact with eyeglass 4 are divided into 32 equal portions equably by pad radial slot 12, form 32 pad claws 14.
