Be a kind of integral type refraction of the utility model light microscope as shown in Figure 1, be wholely set.Top cover 11 and bottom 12 are harmonious, and form shank 1.Top cover is also provided with battery cover 13, can be microscope and change battery after removing.
Fig. 2 shows microscopical inner structure, omits top cover 11.Microscope comprises eyepiece component 3, objective lens unit 4 and rotary cover 2, and rotary cover 2 is arranged at microscope shank 1 near objective lens unit 4 one end, for shielding extraneous veiling glare, avoids impacting user.
Objective lens unit 4 is connected with focusing tooth bar 41, and is limited can move along the optical axis of objective lens unit 4 and eyepiece component 3 by the track arranged in shank 1.Focusing handwheel 42 has part edge to penetrate top cover 11 and bottom 12 respectively, and user can carry out rotation to it and regulate, thus rotation followed by the focusing gear of setting coaxial with it.And gear of focusing engages with focusing tooth bar 41, thus the rotation of focusing handwheel 42 drives focusing tooth bar 41 to move, and then drives objective lens unit 4 along the movement of optical axis direction, changes its distance relative to eyepiece component 3, thus realizes focusing.
Fig. 3 shows the microscopical illuminator of this refract light, and mainly comprise coaxial-illuminating lamp 51, oblique illumination lamp 52, coaxial-illuminating knob 53, oblique illumination knob 54, two joint dry cell 55, the annexes such as wire are not shown.
Composition graphs 2, coaxial-illuminating lamp 51 is arranged for ring-type, be evenly distributed with 12 pieces of light emitting diodes, and microscopical optical axis (line of eyepiece component 3 and objective lens unit 4 optical centre) is by its center.The coaxial-illuminating lamp 51 that ring-type is arranged decreases the formation of shade, and coaxial-illuminating lamp 51 by coaxial-illuminating knob 53 gauge tap and brightness, thus is supplied to the lighting condition that user is suitable for from the front of observing object.
In addition, microscope is also other in optical axis side is provided with oblique illumination lamp 52 at angle, is also light emitting diode, in order to from the direction tiltedly entered at observed surperficial projecting light, in order to highlight the concavo-convex situation on observed surface, and help to observe the situation through observing object inside behind surface.Oblique illumination knob 54 controls switch and the brightness of oblique illumination lamp 52, provides suitable lighting condition.
In some cases, also coaxial-illuminating lamp 51 and oblique illumination lamp 52 can be combined, more clearly observational study object.
It should be noted that, in order to provide stable lighting condition, coaxial-illuminating lamp 51 and oblique illumination lamp 52 are set to be fixedly connected with shank 1, thus constant relative to irradiated surface location, do not move in microscopical focussing process with objective lens unit 4.
Fig. 4 shows the installation site of rotary cover 2 on shank 1, and wherein in order to be described clearly, still omit top cover 11 and show the annexation of rotary cover 2 and bottom 12, rotary cover 2 is consistent therewith with the connection of top cover 11.Only illustrate for schematic structure herein.
Rotary cover 2 offers relative two main locating slots 21 and two locating slots 22, and bottom 12 is correspondingly provided with main locating shaft 24 and time locating shaft 25, and main locating shaft 24 stretches in main locating slot 21, secondary locating shaft stretches in time locating slot 22.Top cover 11 has identical structural design with bottom 12, repeats no more.
Fig. 5 shows the structure of rotary cover 2.
When needs change microscopical viewing angle, rotate rotary cover 2, main locating slot 21 and time locating slot 22 slide relative to main locating slot 24 and time locating shaft 25 respectively.The benefit not arranging fixed rotating shaft is, less on the impact of light path in the process of adjustment rotary cover 2.
In addition, in order to rotary cover 2 can be rotated, the motion stepping of rotary cover 2 can be made again, thus can not automatically change position due to factors such as self gravitations, also be provided with gear mechanism, be not difficult to find out by Fig. 6.Wherein, spring leaf 26 and main locating slot 21, secondary locating slot 22 are similar, are also symmetrically arranged, and are provided with contact, namely protruding, coordinate gear hole 23 to realize stepping.
Rotary cover 2 in Fig. 5 is provided with discrete gear hole 23 on its movement locus relative to spring leaf 26 projection, and gear hole 23 is blind hole.Further, the quantity of every side gear hole 23 is 7, and every flat spring sheet projection quantity is 2.With the situation explanation of side.Operationally, projection blocks two gear hole that mesophase spherule separates 1 gear hole, and the quantity due to gear hole 23 is 7, and whole adjustment process has altogether 5 gears.Every side arranges two projections, can reducing each projection stress in contact site of gear hole 23 reducing wear when regulating, increasing the service life; Also can reach better position-limiting action simultaneously, strengthen result of use.
Interval gear hole is also nonessential.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
