Description

Multifunctional building blocks type simple optical teaching aid

A kind ofly can observe various optical phenomenas and teaching aid--the simple and easy optics teaching aid of multifunctional building-block that carries out Experiments of Optics by making up some optical elements.

General geometrical optics and Optical-Physics Experiment are carried out on optical bench and optical bench, because costing an arm and a leg, be limited to the laboratory uses, be difficult to popularize, learn optical knowledge to the student and bring difficulty, press for that a kind of convenience is simple and easy can carry, and inside and outside the classroom built at any time, to carry out the teaching aid of some Experiments of Optics.

The object of the present invention is to provide a kind of simple in structure, a tractor serves several purposes, directly perceived visual good, the instruments used for education of middle school Experiments of Optics class had both been can be used as, can be used as the toy of the intelligence development in the student second classroom again, finishing the experiment of whole Experiments of Optics in middle school and part university ordinary optical, and then the building blocks of doing it yourself make up the optics teaching aid of multiple simple optical instrument.

The utility model is to implement like this: partly be made up of rectangular box and basic optical components and parts two.Custom-designed multi-functional box body mainly is made of with going to the bottom loam cake, and the same optical bench of class on this box body function is a matrix with this box body, both can be used as the guide rail of horizontal optical system, the support of vertical optical system, also can be used as the instrument box.Limited several optical components are the lens of five kinds of different focal and the lens-mount adaptive with it, and lens place to compress in this dismountable framework and with the lens pressing plate and promptly constitute lens combination, then are a support and aperture when being not interposing at lens; Custom-designed multi-functional target diaphragm can constitute slit, aperture and object; Also have plane mirror, polaroid, diascope and frosted slide etc.Purpose of design can be satisfactorily finished in the apolegamy combination of above-mentioned components and parts and box body.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

The loam cake of Fig. 1, box body (a) and (b) structural representation of going to the bottom;

Lens (the T of Fig. 2, five different focal ₁-T ₅);

Fig. 3, plane mirror, diascope and frosted glass;

Fig. 4, lens frame structure synoptic diagram;

Fig. 5, target diaphragm structural representation;

Fig. 6, focal length of lens measurement mechanism synoptic diagram;

Fig. 7, polarized light phenomena demonstration testing figure;

Fig. 8, simple and easy spectrometer device synoptic diagram.

Wherein, 1 loam cake, 2 go to the bottom, 3 edge strips, 4 scales, 5 box bodys, 6 five lens, 7 plane mirrors, 8 diascopes, 9 frosted glass, 10 prisms, 11 polaroids, 12 frameworks, 13 lens pressing plates, 14 target diaphragms, 15 plate washers, 16 slide plates, 17 light sources, 18 graduated scales.

As shown in Figure 1, constitute by the identical loam cake 1 of structure and go to the bottom 2 box bodys that match 5 that constitute and cover basic optical components and parts, and

loam cake

1 and 2 the long margin frame internal fixation of going to the bottom are wear-resisting, resilient edge strip 3, so that translation therein and energy clamping optical component,

loam cake

1 and 2 the inner bottom surface long axis direction of going to the bottom are provided with graduated scale 4, comprehensively play the usefulness of optical bench or optics guide rail, there are semicircle orifice A and B in the

loam cake

1 and 2 two the long end face central authorities that go to the bottom, use as the optical window of instrument container when coincideing into box body 5 with going to the bottom as the light hole of optical system or when loam cake, also be provided with C and D semicircle orifice on the

loam cake

1 and 2 long margin frames of going to the bottom, during as vertical optical path go into perforation or perforation hole is used.Two distance of center circle summits of the semicircle orifice of nearest neighbor (as A and C) (as the O point) are equidistant, and the ratio of the length and width height of box body is 3:1:1.The certain flexible rubber elastomeric material of above-mentioned edge strip 3 usefulness is made.

The basic optical components and parts are to be carved with the square diascope 8 of cross curve and plane mirror 7 each two, 9 one in frosted glass, the quadra 12(that five focal lengths (f) are respectively 5,10,15 ,-10 ,-15 optical lens 6 and suitable with it five lens sees Fig. 4), a prism 10, polaroid or three-dimensional film glasses 11 and a target diaphragm 14(see Fig. 5).Above-mentioned optical component putter in box body, its frame yardstick should match with box body.Said frame 12 is round-meshed structures in the foreign side that has a dovetail groove, the lens pressing plate 13 that central authorities also are provided with circular hole can slide on dovetail groove, and can compress the lens that are placed in one, 14 of target diaphragms are by framework 12, be provided with thereon the slide plate 16 of aperture and object " 1 " and fixedly plate washer 15 constitute, slide plate 16 slidably also can take off on dovetail groove, fixedly plate washer then can not, should guarantee in the design that object " 1 " is positioned at the central part of whole framework, and when slide plate 16 during along optical axis Rotate 180 °, aperture on it also is in framework central authorities, to adapt to the light path requirement.

Be not difficult to be assembled into periscope, microscope, Galileo and Kepler telescope, slide projector, camera, projector, polariscope by above optical component and box body, and can demonstrate pinhole imaging system, single slit diffraction, Newton ring, the checking reflection law carries out the focal length of lens and measures, and then the composite design periscope of looking in the distance, reflecting telescope, the blank of multiple optical instrument such as spectrometer, Fig. 6～8 are as typical example.

The utility model is rational in infrastructure, and is simple for production, with low cost, be easy to popularize, intuitive is good, can be combined into enough Experiments of Optics with minimum optical component, being the good optical block toy of the senior intelligence development of student, also is the indispensable demonstration teaching aid of middle school Experiments of Optics class.
