Description
Technical field
The utility model relates to a kind of stereomicroscope eyesight adjustment device, especially a kind of built-in cross-graduation plate
Stereomicroscope diopter adjustable mechanism.
Background technique
Common stereomicroscope eyepiece diopter structure type can be divided into fixed and adjustable, fixed eyepiece diopter knot
Structure is simple, and shock resistance, shock resistance are good, and leakproofness easily guarantees；Diopter is generally located at by fixed eyepiece diopter structure to be made just
In the range of the people of normal eyesight can clearly observe and the focal length of its binocular eyepiece is fixed；But the eyesight of different people is thousand
Poor ten thousand is other, even the same person, binocular vision is also possible to be different, thus uses fixed eyepiece diopter structure
Stereomicroscope cannot will see simultaneously that sample does not feel good because of eyes and answer；In order to solve this problem, stereoscopic aobvious
The eyepiece diopter structure of micro mirror be made into it is adjustable, adjust diopter when its eyepiece focal length be also variation, to better adapt to
The focal power of various human eyes improves instrument service precision, a kind of utility model patent " stereomicroscope eyepiece of my company's application
Diopter adjustable mechanism " (application number: 201720542362.2) be exactly it is adjustable, the structure is easy to use, but this adjustable side
Formula cannot be in the application of the wherein built-in auxiliary member such as cross-graduation plate measured size, because wanting built-in cross-graduation plate must
Need ask it with respect to eyepiece be it is motionless, i.e., with respect to eyepiece, there is no rotating and cross-graduation plate and eyepiece cross-graduation plate
The distance between require be constant；It such as wants built-in cross-graduation plate or cross-graduation plate is placed on its movable component,
It is placed on the component of its fixation；And this structure is when rotating its diopter ring, movable component is that opposite eyepiece is rotation
Turn and drive eyepiece mobile, if be placed in movable component, be unsatisfactory for cross-graduation plate with respect to eyepiece there is no
The condition of rotation；But if being placed in fixed component, then being unsatisfactory for the requirement of the distance between cross-graduation plate and eyepiece is
Constant condition；The application of built-in cross-graduation plate thus can not be all carried out inside it.
Summary of the invention

It is moved in the helicla flute 5 on straight-line groove 12,4 inner hole hole wall of helicla flute diopter focusing drum on groove drum 3；Force tight nut 6 and straight line
The lower end outer-diameter threads of groove drum 3 connect, and clamp helicla flute diopter focusing drum 4, but helicla flute diopter focusing drum 4 can freely turn
It is dynamic；Design has helicla flute 5 on the inner hole hole wall of helicla flute diopter focusing drum 4, and the size of slot and the head sizes of pin 11 match
It closes, rotates helicla flute diopter focusing drum 4, helicla flute 5 of the pin 11 on its inner hole hole wall can be made to move；Straight line groove drum 3 passes through
The screw thread of its bottom diameter is connect with the outer diameter of connecting cylinder 7, to be attached with microscope body 8；It opens 3 side of straight line groove drum
There is the straight-line groove 12 of a up and down direction, the size of straight-line groove 12 is matched with the head sizes of pin 11；The side of moving cylinder 13
Be provided with threaded hole, connect by it with the screw rod of pin 11, can make moving cylinder 13 with pin 11 in straight line groove drum 3 on move down
It is dynamic, mobile range by straight-line groove 12 length limitation；Helicla flute diopter focusing drum 4 is rotated, pin 11 can be made along its inner hole hole
Helicla flute 5 on wall is mobile, and pin 11 is then forced to move up and down and moving cylinder 13 in the straight-line groove 12 of straight line groove drum 3 simultaneously
And then it can only move up and down and cannot rotate, then with eyepiece connect cylinder 14, eyepiece 1, eyepiece stalk 2 is upper and lower together for the movement of moving cylinder 13
It is mobile；Due to being equipped with the cross-graduation plate 10 locked by graticle retaining ring 9 in 14 lower end of eyepiece connect cylinder, thus rotate spiral
Slot diopter focusing drum 4, cross-graduation plate 10 can follow eyepiece 1 to move up and down and cannot rotate and keep at a distance from eyepiece 1
It is constant, meet the requirement of built-in cross-graduation plate 10.
The beneficial outcomes of the utility model are, which can respectively be self-regulated left and right eyepiece
Diopter is suitable for the different eyesights of different stereomicroscope users, can easily make up to optimal visual effect
Fruit, and the structure can built-in cross-graduation plate, the application of stereomicroscope can be expanded, improve instrument service precision and effect
Rate.
