Abstract

The utility model relates to a microscope, comprising an insertion type eye lens and a rotary lens mount. The rotary lens mount is provided with two rotary and changeable object lenses. When only the object lenses are used for observation, an observed object can be magnified by 50 times and 100 times. When the object lenses and the eye lens are combined for observation, an observed object can be magnified by 250 times to 450 times. When an upper lens tube is stretched, an observed object can be magnified by 500 times. A specimen frame is provided with a longitudinally and horizontally regulating handle which enables a specimen to move around. A reflective mirror can freely select an optimum angle. A base can be provided with a 3V power source inside. In dark, the reflective mirror is rotate to enable a bulb which is arranged at the back to direct to an object to be observed and then the object can be observed.

Description

Pocket microscope

The utility model relates to a kind of microscope.

Present commercially available microscope camera lens system combines with the multi-disc concave-convex lens, and the camera lens consumption is big, require high, produce complexity, cost high, cost an arm and a leg, common people and student are difficult to bear, and volume carries difficulty greatly.

The purpose of this utility model be exactly for to people especially to students in middle and primary schools provide a kind of with low cost, superior performance, volume little, can and make the pocket microscope of the usefulness of overview for teaching.

Technical solution of the present utility model:

A kind of pocket microscope, it includes base 1 and microscope base 2, it is characterized in that being provided with in the trapezoidal microscope base 2 reflective mirror 10 that can radially freely adjust angle, the microscope base outer wall of corresponding reflective mirror mirror position has into optical gate, there is draw-in groove both sides, but are provided with the sample frame 5 that portraitlandscape is regulated on the top of microscope base 2, and microscope base upwards is connected with the mirror holder 16 that can regulate lifting, mirror holder 16 centers are provided with single lens camera lens 19, and the open-work 23 on this camera lens 19 and the microscope base 2, reflective mirror 10 are on same axial line.

The utility model only adopts a slice eyepiece and a slice object lens, and object lens mirror holder and base, microscope base, reflective mirror are formed one, can observe use separately, with scalable 250 to 500 times of lens barrel combination back, superior performance, complete machine adopts moulding except that individual part, and structure is also simplified greatly, its cost is very cheap, only need several yuans, and volume is little, is easy to carry, be that articles for use are popularized in inexpensive science and education, good market outlook are arranged.

Fig. 2 is a side of the present utility model diagrammatic cross-section.

Fig. 3 is a sample frame schematic perspective view of the present utility model.

Fig. 4 is that reflective mirror of the present utility model is adjusted the handle synoptic diagram.

Fig. 5 is the utility model schematic perspective view.

Two-layer about in the of 5 minutes as Fig. 1-Fig. 5 sample frame of the present utility model, there is the slot 24 of placing cover glass 20, microslide 21 on the upper strata, there is semicircular steep-pitch thread 25 lower left, the lower floor center is except that having square opening 26, little shelves limit 27 is arranged above the both sides, there is semicircle groove 28 on the lower floor upper left side, and the coarse pitch screw rod of transverse screw handle 9 promptly installs in groove 28.The lower floor bottom has two short cylindrical pins 30 to vertically move along the groove about 29 on microscope base 2 tops, and there is steep-pitch thread 32 lower floor bottom fluted 31 and microscope base 2 upper ends, and the screw rod setting of longitudinal screw handle 4 wherein.

Base 1 of the present utility model and microscope base 2 are adjusted handle 3 by two side bayonet slots and reflective mirror and are linked together, and a side of these handle 3 middle part cydariform parts is provided with reflective mirror 10.Opposite side is provided with 2.5V spot light lamp bulb 22, and microscope base 2 bottom circular arcs and base 1 top circular arc kiss connect, and is that axle center microscope base 2 can tilt forward and back about 35 degree with handle 3.

The utility model is furnished with telescopic lens barrel 8 and the following lens barrel 7 gone up, and the upper end of last lens barrel 8 is provided with monolithic eyepiece camera lens 17.The coarse pitch groove is arranged on the external diameter, and the lower end of following lens barrel 8 has the endoporus of step and mirror holder 16 to plug.

When the utility model product uses sample or observing object are placed between cover glass 20 and the microslide 21, be placed on presser feet 6 times, adjust reflective mirror handle 3, make reflective mirror aim at observing object, adjust focal length handwheel 14 again, till focal length the best.Screw 15 can drive mirror holder 16 liftings, and spring 13 can make mirror holder 16 up and down balance systems.When using separately object lens to observe scalable 50 and 100 times, patch and will descend lens barrel 7 to insert in the shrinkage pool of mirror holders 16 when eyepiece is observed, adjust focal length handwheel 14, this moment can be with mark

This amplification 250-450 doubly if it is moving to go up the lens barrel counterclockwise rotation, when elongating the extreme higher position along coarse pitch, can increase to enlargement factor 500 times.Mobile can the adjustment of sample vertically moves screw handle 4 and horizontal mobile screw handle 9, and the 5 commercially available sections of sample frame are general, made things convenient for teaching and user.Two single lens camera lenses can be according to pin 18 rotation transposings.Microscope base 2 and base 1 binding site person's needs according to the observation tilt about 35 degree, can use 3V battery 12 when light is dark.Open switch 11 and adjust handle 3, make spot light lamp bulb aim at observing object, very easy to use.
