Abstract

The utility model relates to an optical instrument of a grouping experiment for the nature study of primary schools. The light source of the utility model is composed of electric beads, a lamp socket and a collecting lens which are matched with a battery supporting rack and a switch to form integration. The electric beads are installed in the lamp socket. The collecting lens is installed in a lens barrel. The lens barrel is sheathed on the front end of the lamp socket and is matched with the inside diameter of the lamp socket in a slide mode. The end part of the battery supporting rack is connected with a bracket upward. Both ends of the arc-shaped piece of the upper end of the bracket are hinged with both ends of a circular ring. The circular ring is tightly sheathed on the outer ring of the lamp socket. The light source of the utility model can be adjusted discretionarily. The utility model is reliable in performance and very ideal in experiment effect.

Description

Primary optical experiment box

The utility model relates to the optical instrument that a kind of nature study student experiment in group is used.

At present, nature study requires the student to do some the most basic Experiments of Optics, for example does converging action, the convex lens imaging of refraction, the convex lens of rectilinear propagation, shadow, pinhole imaging system, reflection of light, periscope light path, the light of light, the experiments such as chromatic dispersion of light.The Experiments of Optics box of usefulness is mainly by level crossing, convex lens, post lens, prism, single seam light hurdle now, optical element and a plurality of corresponding light tool socket and light source compositions such as many seam light hurdle, aperture plate, optical screen, candle stick, in actual experiment, the performance of light source is one of key factor that influences experiment effect, the light source of existing optics box only is contained in Spot light bulb on the lamp socket, there is not collector lens, because the main application of Spot light bulb is in the tourism torch, as illumination, only need optically focused, do not want directional light, so the experiment effect of this light source is undesirable.In addition, the optical parametric of Spot light bulb is very inconsistent, and it is a consumable accessory also, is difficult for being fitted on the suitable small electric bulb of parameter after the damage, influences experimental result, and, being unworthy of battery case in the existing optics box, also need join in addition during use, very inconvenient.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of primary optics easy to use, that experiment effect is good to test box.

Technical solution of the present utility model:

A kind of primary optics experiment box, it includes box body, level crossing, convex lens, the post lens, prism, single seam light hurdle, many seam light hurdle, aperture plate, optical screen, optical element and light tool socket and light sources such as candle stick, it is characterized in that wherein light source is by common small electric bulb 4, lamp socket 1, collector lens 5 is formed, and form a whole with battery carrier 7 and switch 8, small electric bulb 4 is contained in the lamp socket 1, collector lens 5 is contained in the lens barrel 3, lens barrel 3 is enclosed within the front end of lamp socket 1, be slidingly matched with lamp socket 1 internal diameter, make that lens barrel 3 can be elastic in lamp socket 1, outgoing beam is adjusted to directional light; Upper surface upwards is connected with support 6 in the end of battery carrier 7, the two ends of the arc-like sheet 10 on support 6 tops and the symmetrical two ends of annulus 2 are hinged, annulus 2 just tightly is enclosed within on the outer ring of lamp socket 1, make lamp socket 1 can rotate around the pin joint of arc-like sheet 10 with annulus 2 together with collector lens tube 3, to adjust the elevation angle of irradiating light beam, battery carrier 7 is also used as light source base.

The utility model organically is combined into one battery carrier and light source, small electric bulb and collector lens are connected as a single entity, its light source dependable performance, can adjust light source by collector lens, experimental result is very good, the utility model is simple and compact for structure, only adopts a light tool socket that can insert various optical elements, uses convenient.

Fig. 1 is a light-source structure synoptic diagram of the present utility model;

Fig. 2 is a smooth tool socket synoptic diagram of the present utility model.

As Fig. 1, battery 9 is installed on the battery carrier 7, closes a switch 8, then small electric bulb 4 is luminous, before and after regulate lens barrel 3 and promptly regulate the focal length of collector lens 5 and make the light of small electric bulb 4 become parallel beam to penetrate, collector lens 5 with also can be the collector lens group of forming by two lens, they also are installed in the lens barrel 3.In the light source, lamp socket 1 can rotate in annulus 2, makes the filament of small electric bulb 4 can be adjusted at easily on level, the vertical or any direction, guarantees the dependable performance of light source.The utility model only adopts a light tool socket 11, there is the circular hole 12 of a projection at its upper surface center, to insert lens or candlestick, and the centre of upper surface and a side are provided with two group slots 13 of projection, to insert optical elements such as light hurdle, optical screen, be provided with a group slot 14 in the opposite side side of light tool socket 11, be used to insert level crossing, this light tool socket 11 inserts different optical elements can make different Experiments of Optics with light source cooperation of the present utility model, and effect is very desirable.
