Abstract
The utility model relates to a miniature stereo-magnifier whose interpupillary distance and visibility are both adjustable, comprising a spectacle frame and a magnifying glass. The spectacle frame is fixed with a bracket, and two reeds are installed whose one side ends are respectively connected with the magnifier and whose other side ends are fixed on the bracket. The middle of the reed is provided with an interpupillary adjustment wheel, and the interpupillary distance of the magnifier can be adjusted after the interpupillary adjustment wheel is adjusted. The optical axis of the miniature stereo-magnifier always maintains consistent after the interpupillary distance is changed, and the utility model has the characteristics of light weight and strong versatility, suitable for operation, archaeological fine carving, and precision instrument & meter assembling and repairing.
Description
The utility model relates to particularly a kind of interpupillary distance of a kind of miniature stereoscopic magnifier, miniature stereoscopic magnifier that diopter is all adjustable.
At present miniature stereoscopic magnifier has two kinds, and one be interpupillary distance and all fixing miniature stereoscopic magnifier of diopter, and it is suitable for individual's application, and according to user's interpupillary distance, diopter customizes, so versatility does not have, and the technology of production is relatively poor, and cost is also higher.Two is all adjustable miniature stereoscopic magnifier of interpupillary distance and diopter, because the interpupillary distance gap is big (generally at 50-70mm), adopt the guiding rail formula to adjust machinery, though solved the adjustment of above-mentioned interpupillary distance, highly versatile, but in interpupillary distance change process, optical axis will rock, the consistance of destroying optical axis makes resembling of observing visually fuzzy, user's eyes tire easily.And mechanism's complexity, it is a lot of that weight is increased.
The purpose of this utility model is the deficiency in view of above-mentioned miniature stereoscopic magnifier, designs a kind of interpupillary distance, and diopter is all adjustable, and in the process that changes interpupillary distance, optical axis is difficult for change, and is simple in structure, the miniature stereoscopic magnifier that cost easy to use is low.
The utility model is a kind of miniature stereoscopic magnifier, and it has mirror holder, magnifier, it is characterized in that fixing a support on mirror holder, has two reeds, one end to fix a magnifier respectively, and the other end is fixed in support, establishes an interpupillary distance regulating wheel in the centre of reed.Regulating wheel rotates, make the chucking nut synchronous backward motion of regulating wheel two sides, it is identical making magnifier interpupillary distance regulating wheel rotational synchronization oppositely transport elastic force, when the interpupillary distance regulating wheel is regulated, two reeds are always with respect to the displacement of mirror holder symmetry, magnifier is fixed on the reed, after in case the optical axis of left and right sides magnifier is corrected and makes the reed setting, because even reed has good recovery capability thereby is subjected to external impacts left and right sides magnifier in elastic limit optical axis is difficult for change, guarantee like this to remain unanimity in the adjustment of optical axis.And because mechanism is simple, in light weight, it is also easy to produce, cost is lower.
Be elaborated with reference to the accompanying drawings below:
Fig. 1 is the synoptic diagram of miniature stereoscopic magnifier;
Fig. 2 is the magnifier synoptic diagram.
Miniature as can be seen from Figure 1 stereoscopic magnifier has mirror holder 1, a support 2 is fixed in the upper end in the middle of mirror holder 1, two reeds, 3 one ends respectively fixedly magnifier 4 other ends be fixed on 2a in support 2 pickup grooves, fix with screw, establishing a regulating wheel 5 between two reeds, 3 middle-ends has two chucking nut 5a, 5b, reed 3 that outside tension force is arranged at two ends of regulating wheel 5, and fixing chucking nut 5a, 5b, when adjusting regulating wheel 5, the motion of reed 3 synchronous backwards drives magnifier 4 and moves the interpupillary distance of adjusting magnifier 4 like this.
Fig. 2 is that it of magnifier is made up of eyepiece 6 and object lens 7, and eyepiece 6 can be regulated by screw thread with the spacing of object lens 7, like this our the different diopter of adjusting that just can pass through.
The utility model is one to be applicable to medical operating, the historical relic archaeology, the precision optical instrument that industries such as precision instrumentation assembling, repairing, hand work engraving are used, its interpupillary distance, the all adjustable versatility of sighting distance is very strong, the optical axis unanimity, lightweight energy user obtains the miniature stereoscopic magnifier of promising result.
Claims (3)
