Abstract

The utility model aims at providing a microscope focusing mechanism that focusing precision is high, simple structure, convenient to use, its lens cone is connected with the bull thread bush, and bull thread bush and bull thread seat are with bull thread connection, bull thread seat and focusing seat threaded connection, and the axial of bull thread bush is opened there is the guide way, sets up the locating plate that stretches into in the guide way on the focusing seat.

Description

Focusing of microscope mechanism
Technical field
The utility model relates to the particularly focus adjusting mechanism of digit microscope of a kind of microscope.
Background technology
At present, the gear that is equipped with on the microscopical lens barrel of known Photobiology is connected with focusing knob, is equipped with on the brandreth of lens barrel and is provided with tooth bar.By rotating focusing knob, make gear move up and down at the moving realization of tooth bar Shang Roll lens barrel.The digit microscope of having announced does not still break away from the traditional structure of optical microscope, and its volume is big, and heaviness is not easy to the meticulous focusing of digit microscope, has influenced the sharpness of imaging.
Summary of the invention
The purpose of this utility model provides a kind of focusing accuracy height, focusing of microscope mechanism simple in structure, easy to use.
Focusing of microscope of the present utility model mechanism, lens barrel is connected with the multi-step thread cover, and the multi-step thread cover is connected with multi-step thread with the multi-step thread seat, and the multi-step thread seat is threaded with focusing mount, multi-step thread cover axially have a gathering sill, the location-plate that extend in the gathering sill is set on focusing mount.
Its course of work: the multi-step thread seat rotates (with respect to focusing mount), because of the multi-step thread that cooperates with the multi-step thread seat overlaps because the location-plate restriction can not be rotated, so the multi-step thread cover is merely able to move up and down vertically.Multi-step thread puts the connection lens barrel again, and lens barrel just moves up and down, and realizes the focusing function.
As the further improvement to above-mentioned focus adjusting mechanism, the upper surface of described multi-step thread seat has arc groove, and the register pin that extend into arc groove is housed on the focusing mount.Because the register pin on the focusing mount stretches in the arc groove on the multi-step thread seat, the multi-step thread seat can only rotate in the arc chord angle scope of arc groove correspondence with respect to focusing mount.
As the further improvement to above-mentioned focus adjusting mechanism, it also comprises the focusing ring that is arranged on multi-step thread seat outside and is connected with the multi-step thread seat; Focusing ring top is provided with cover plate, and lens barrel passes cover plate and is connected with the multi-step thread cover.This structure makes multi-step thread seat, multi-step thread cover be enclosed in focusing ring and cover plate inside, prevents that dust from entering multi-step thread seat, multi-step thread cover.Focusing ring can be fixedlyed connected with the multi-step thread seat by the screw that radially is provided with.
As the further improvement to above-mentioned focus adjusting mechanism, the mode that multi-step thread seat and focusing mount are rotationally connected is a thread connecting mode.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Focusing of microscope mechanism shown in Figure 1, preceding lens barrel 1 screws in multi-step thread cover 3 and connects with STRTHD.Multi-step thread cover 3 screws in multi-step thread seat 6 inside and connects with multi-step thread, and the upper surface of multi-step thread seat has arc groove 12.Three screws 10 of radially packing into from 7 the side of focusing are fixedlyed connected focusing ring 7 with the lower end of multi-step thread seat 6.The STRTHD that focusing mount 8 tops screw in multi-step thread seat 6 and multi-step thread seat 6 outsides is connected, rotates focusing ring 7 and makes multi-step thread overlap 3 lower end and focusing mount 8 upper ends at grade.Insert on the multi-step threads cover 3 two to two location-plates 9 along in the axial gathering sill of opening 11 of multi-step thread cover this moment, and with two screws location-plate 9 is fixed on the focusing mount 8.With a location screw 5 and two common screws focusing mount 8 is fixed on the microscopical main body then, rotation focusing ring 7 is loaded onto register pin 4 at the other end of the arc groove 12 of multi-step thread seat and is fixed on the focusing mount 8.Rotate focusing ring 7, locate the angular range that screw 5 and register pin 4 rotate at multi-step thread seat arc groove inner control focusing ring 7 respectively this moment, just controlled the scope that moves up and down of lens barrel.Connect with STRTHD the inside of being inserted in precession focusing ring 7, the upper end of lens barrel 1 with cover plate 2 at last in the past.Rotate focusing ring 7 and become rotatablely move into moving up and down of lens barrel, because multiple-threaded effect reliable and stable purpose when reaching moving up and down of accurate focusing and preceding lens barrel.
Preceding lens barrel and multi-step thread cover connect into one, and the multi-step thread cover screws in the multi-step thread seat.Multi-step thread seat external diameter is a STRTHD, and this screw thread is connected with focusing mount internal diameter STRTHD, and overlaps moving direction with location-plate control multi-step thread.On the multi-step thread seat, have the arc groove of certain angle scope in addition, the two ends installing and locating pin of groove and location screw, focusing ring is connected with screw with the multi-step thread seat, rotate focusing ring and drive the rotation of multi-step thread seat, the scope of the anglec of rotation of register pin and location screw control focusing ring, so just can make that lens barrel moves up and down, and the distance that lens barrel moves up and down is controlled at also in certain scope, makes lens barrel can not run into the glass of biologic slice on the objective table.By the multi-step thread focus adjusting mechanism focusing ring is rotatablely moved and to become the rectilinear motion up and down of lens barrel.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts the multiple thread focusing structure both to solve lens barrel move mode problem, has improved again focusing accuracy, The digital micrograph image stabilization is clear. The utility model is skillfully constructed, volume is little, compact simple and practical, the adjusting essence of reliable in structure Degree height, good stability and manufacturing cost are low. Be applicable to the accurate machine construction of simple microscope and digit microscope, should Extensive with prospect.
