Abstract
The utility model relates to a reading microscope. In the utility model, a base bracket of the microscope is fixed with a cantilever which is fixed with a drawtube; a moving mechanism is arranged between the cantilever and the drawtube which is divided into an eye lens connecting cylinder part and an objective lens connecting cylinder part; the objective lens connecting cylinder is arranged at the vertical direction; the upper part of the objective lens connecting cylinder is connected with a prism cylinder; the prism cylinder is fixed with the eye lens connecting cylinder; the axis of the eye lens connecting cylinder has an angle alpha relative to the axis of the objective lens connecting cylinder; the inner part of the prism cylinder is provided with a turning prism. The eye lens connecting cylinder of the utility model is sloping towards horizontal direction causing people to observe sitting on chairs, and the utility model has the advantages of comfort work and convenient adjustment.
Description
The utility model belongs to optical instrument.
Reading microscope is an optical metrological instrument, and its range of application is wider, and present this microscope is a straight barrel type, and the people must be the posture of standing when observation, and is very uncomfortable.And the straight barrel type microscope lens barrel moves up and down uses friction wheel mechanism, adjusts inconvenient.
The purpose of this utility model is to provide a kind of reading microscope that can sitting posture observation.
The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises a Microscope base, a support is arranged on the base, fix a cantilever on the support, fixed lens barrel on the cantilever, be provided with travel mechanism between cantilever and lens barrel, lens barrel of the present utility model is divided into eyepiece extend neck and object lens extend neck two parts, the 5 vertical direction settings of object lens extend neck, object lens extend neck top connects a prism tube 4, fixed eyepiece extend neck 1 on the prism tube, the axis of eyepiece extend neck has an angle [alpha] with respect to object lens extend neck axis, is provided with one in the prism tube and turns to prism 9, makes light refraction to eyepiece, transverse moving mechanism between the utility model cantilever and lens barrel adopts screw structure, leading screw 6 is fixed on the cantilever by the leading screw support, and the object lens extend neck is fixed on by contiguous block 8 on the screw 7 that is enclosed within on the leading screw, adopts rack and pinion axle construction to adjust moving up and down of eyepiece extend neck between the object lens extend neck, gear shaft 3 is fixed on the contiguous block of object lens extend neck, and tooth bar 2 is fixedly on the object lens extend neck.
Eyepiece extend neck of the present utility model tilts to horizontal direction, the people can be sitting on the chair observe, and it is pleasant to work, and microscopical adjusting mechanism is provided with rationally, and is easy to adjust.
Accompanying drawing 1 is the utility model structural front view;
Accompanying drawing 2 is the utility model screw structure cut-open view;
Accompanying drawing 3 is the utility model prism tube cut-open view.
Embodiment
Eyepiece extend neck axis and object lens extend neck axis angle α are 45 °, 45 ° at prism vergence angle, 50 millimeters of the horizontal mobile ultimate ranges of microscope, 50 millimeters of vertical mobile ultimate ranges.The eyepiece extend neck can be with the axial rotation of prism tube around the object lens extend neck.
