Abstract
The utility model relates to a kind of novel throwing face demonstrator, and it comprises two the throwing face be arranged symmetrically with mirrors, and two throwing face mirrors are linked together by a telescopic rod; On described telescopic rod, corresponding two focus places of throwing face mirror are respectively equipped with a light source and dash receiver, and described light source can send a branch of directional light from the focus of the face of throwing mirror; The inside surface of described throwing face mirror is smooth mirror surface structure; Described light source is rotatable, is convenient to the angle regulating incident light.The utility model is convenient to the optical property that student understands its focal point, all brings a lot of convenience in teaching process Faculty and Students, can demonstrate intuitively, also make student understand the principle of reflection of light fully, is convenient to understand and memory.
Description
Technical field:
The utility model relates to teaching aid apparatus field, relates to a kind of novel throwing face demonstrator in particular.
Background technology:
The reflection law of light was gone to school in junior physics, an optical property is had: any reflected light of light after parabolic reflective passing through focus is all parallel with parabolical axis of symmetry for its focal point, otherwise any light parallel with para-curve axis of symmetry all passes through its focus after parabolic reflective.For the optical property of its focal point, in teaching, all just need student to accept stiffly, can only memorize mechanically, and can not understand from sense organ, all bring a lot of inconvenience in teaching process Faculty and Students.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, a kind of novel throwing face demonstrator is provided, has been had the understanding on sense organ by the optical property of demonstrator to the face of throwing mirror, thus made the connection between theory and practice, deeper understand the reflection law of light, make student increase learning interest.
Technology solution of the present utility model is as follows:
A kind of novel throwing face demonstrator, it comprises two the throwing face be arranged symmetrically with mirrors, and two throwing face mirrors are linked together by a telescopic rod; On described telescopic rod, corresponding two focus places of throwing face mirror are respectively equipped with a light source and dash receiver, and described light source can send a branch of directional light from the focus of the face of throwing mirror.
As preferably, the inside surface of described throwing face mirror is smooth mirror surface structure.
As preferably, described light source is rotatable, is convenient to the angle regulating incident light.
The beneficial effects of the utility model are:
A branch of directional light that the utility model sends through light source, because light source is positioned at the focus place that face mirror is thrown in left side, after the reflection of throwing face, left side mirror, reflected in parallel is thrown on the mirror of face to right side, then through the secondary reflection of throwing face, right side mirror, because dash receiver is positioned at the focus place that face mirror is thrown on right side, light can display on dash receiver.The utility model is convenient to the optical property that student understands its focal point, all brings a lot of convenience in teaching process Faculty and Students, can demonstrate intuitively, also make student understand the principle of reflection of light fully, is convenient to understand and memory.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Embodiment, see accompanying drawing 1, a kind of portable throwing face demonstrator, it comprises two the throwing face be arranged symmetrically with mirrors 1, and two throwing face mirrors are linked together by a telescopic rod 2, telescopic rod is scalable, is convenient to taking of demonstrator, and adjustable two distances of throwing between the mirror of face understand the reflexive property of throwing face mirror; On described telescopic rod, corresponding two focus places of throwing face mirror are respectively equipped with a light source 3 and dash receiver 4, and described light source can send a branch of directional light from the focus of the face of throwing mirror.
The inside surface of described throwing face mirror is smooth mirror surface structure, prevents the scattering of light.
Described light source is rotatable, is convenient to the angle regulating incident light, is convenient to adjustment angle to understand throwing face mirror reflexive property.
Above-described embodiment is the specific descriptions of carrying out the utility model; just the utility model is further described; can not be interpreted as the restriction to the utility model protection domain, those skilled in the art makes some nonessential improvement according to the content of above-mentioned utility model and adjustment all falls within protection domain of the present utility model.
Claims (3)
1. a novel throwing face demonstrator, is characterized in that: it comprises two the throwing face be arranged symmetrically with mirrors, and two throwing face mirrors are linked together by a telescopic rod; On described telescopic rod, corresponding two focus places of throwing face mirror are respectively equipped with a light source and dash receiver, and described light source can send a branch of directional light from the focus of the face of throwing mirror.
