Description
Technical field
The utility model belongs to teaching aid field, particularly a kind of telescope image-forming principle demonstration device.
Background technology
In junior middle school, we all learned Galileo telescope image-forming principle, the object lens of Galileo telescope are convergent lens and eyepiece is the telescope of divergent lens.Light is through the formed real image of object lens refraction in rear (near the people's object rear) focus of eyepiece, and this picture is a virtual image to eyepiece, therefore after its refraction, becomes a upright virtual image of amplifying.But in teaching process, this abstract concept is not easily understood by student, easily has a negative impact to quality of instruction.If can abstract concept is existing by certain teaching aid tool in teaching process, student can be convenient on the one hand and understand, also can cause the interest of Students ' Learning on the other hand.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of telescope image-forming principle demonstration device is provided, in teaching process, by demonstration, the image-forming principle of Galileo telescope is vivo presented in face of student, excite the enjoyment of Students ' Learning, be also convenient to the understanding of student to abstract concept simultaneously.
The technical scheme in the invention for solving the above technical problem is:
A kind of telescope image-forming principle demonstration device, comprise the first carrier base and the second carrier base, be arranged with two coupling shafts between described first carrier base and the second carrier base in parallel, the middle position of two coupling shafts is provided with the 3rd carrier base; First Mobile base that can move freely on coupling shaft is provided with between described first carrier base and the 3rd carrier base, be provided with second Mobile base that can move freely on coupling shaft between first Mobile base and the 3rd carrier base, between described 3rd carrier base and the second carrier base, be provided with the 3rd Mobile base that can move freely on coupling shaft; Described 3rd Mobile base is provided with candlestick, candlestick is provided with candle; Described first Mobile base is provided with imaging cardboard, the second Mobile base is provided with concavees lens, the 3rd carrier base is provided with convex lens.In teaching process, by demonstration, the image-forming principle of Galileo telescope is vivo presented in face of student, excites the enjoyment of Students ' Learning, be also convenient to the understanding of student to abstract concept simultaneously.
As preferably, described second movable stand is provided with concave mirror frame, described concavees lens are embedded in concave mirror frame; Described 3rd carrier base is provided with convex lens frame, and described convex lens are embedded in convex lens frame; Described first movable stand is provided with imaging cardboard deck, the lower end of described imaging cardboard embeds in imaging cardboard deck.
As preferably, described first Mobile base, the second Mobile base and the 3rd Mobile base are located on coupling shaft; The center, upper surface of the first Mobile base, the second Mobile base, the 3rd Mobile base and the 3rd carrier base all offers blind hole; The lower end of described imaging cardboard deck, concave mirror frame, convex lens frame and candlestick is plugged in each blind hole successively, thus is fixed on successively on the first Mobile base, the second Mobile base, the 3rd carrier base and the 3rd Mobile base.
The utility model compared with prior art, have the following advantages and effect: in teaching process, by demonstration, the image-forming principle of Galileo telescope is vivo presented in face of student, excites the enjoyment of Students ' Learning, be also convenient to the understanding of student to abstract concept simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
