Abstract

A light-reflection-proof blackboard belongs to teaching aids and mainly solves the problem that a traditional blackboard reflects light and damages eyesight of students. The blackboard is structurally formed by an installation seat, a main board face, hinges and light reflection boards. The reflection boards capable of rotating through 180 degrees around the axial direction of corresponding hinges are in hinge connection with the left side and the right side of the main board face, the area of the light reflection boards is about half of that of the main board face, and the installation seat used for installing and fixing the blackboard is arranged on the back of the main board face. The blackboard has the advantage of avoiding light reflection harm.

Description

A kind of reflection prevention blackboard

Technical field

The utility model relates to a kind of teaching aid, specifically is a kind of reflection prevention blackboard.

Background technology

Class hour on to the student, for ease of understanding and memory, for key content, teacher can write at blackboard with chalk every now and then, because the design feature of traditional blackboard, defectives such as reflective can appear when being in different angles, the phenomenons such as hypopsia that light pollution causes have endangered the healthy of students greatly, especially be sitting in the student in classroom periphery or corner, so in order to reduce the reflective defective of bringing, sometimes teacher can take a bigger plate object to block light source, and this just gives lessons to teacher and brings very big inconvenience, also influences students and learns normally.

The utility model content

The purpose of this utility model is to provide a kind of reflection prevention blackboard, and this blackboard has the advantages that to avoid reflective harm.

The technical scheme in the invention for solving the technical problem is: a kind of reflection prevention blackboard, its structure is made of mount pad, mainboard face, folding and reflector, what be respectively equipped with in the left and right sides of mainboard face that folding connects can be around the reflector of folding axial rotation 180 degree, described reflector area is about half of mainboard face, is provided with at the mainboard face back side for installing and the fixing mount pad of blackboard.

The beneficial effects of the utility model are: before the use, utilize mount pad that blackboard is fixed on the wall, this moment, the reflector of both sides can freely overturn, when teacher carries out writing on the blackboard, reflector can be turned to parallelly with the mainboard face, mainboard face and reflector were in the same plane and were fitted on the wall this moment; As be positioned at which side student of classroom and feel blackboard reflective light, teacher can suitably rotate the reflector of this side, makes reflector and mainboard face form certain included angle, to block light source, reduces reflective harm; For the grasp degree of course in court, teacher also can turn to the reflector of both sides the place ahead of mainboard face as need examinations student, so that whole mainboard face is blocked, and then the student is putd question to; The utility model is simple in structure, does not hinder carrying out smoothly of teaching, and uses safely, is convenient to operation, and is environment friendly and pollution-free.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Among the figure: 1 mount pad, 2 mainboard faces, 3 foldings, 4 reflectors.

The specific embodiment

As shown in Figure 1.A kind of reflection prevention blackboard, its structure is made of mount pad 1, mainboard face 2, folding 3 and reflector 4, be respectively equipped with the reflector 4 that folding 3 connects in the left and right sides of mainboard face 2, this reflector 4 is made for opaque material, can be around folding 3 axial rotation 180 degree, reflector 4 areas are about half of mainboard face 2, are provided with at mainboard face 2 back sides for installing and the fixing mount pad 1 of blackboard.

Before the use, utilize mount pad 1 that blackboard is fixed on the wall, this moment, the reflector 4 of both sides can freely overturn, when teacher carries out writing on the blackboard, reflector 4 can be turned to parallelly with mainboard face 2, mainboard face 2 was in the same plane with reflector 4 and was fitted on the wall this moment; As be positioned at which side student of classroom and feel blackboard reflective light, teacher can suitably rotate the reflector 4 of this side, makes reflector 4 and mainboard face 2 form certain included angle, to block light source, reduces reflective harm; For the grasp degree of course in court, teacher also can turn to the reflector 4 of both sides the place ahead of mainboard face 2 as need examinations student, so that whole mainboard face 2 is blocked, and then the student is putd question to; The utility model is simple in structure, does not hinder carrying out smoothly of teaching, and uses safely, is convenient to operation, and is environment friendly and pollution-free.

Claims

1. reflection prevention blackboard, it is characterized in that, constituted by mount pad, mainboard face, folding and reflector, what be respectively equipped with in the left and right sides of mainboard face that folding connects can be around the reflector of folding axial rotation 180 degree, described reflector area is about half of mainboard face, is provided with at the mainboard face back side for installing and the fixing mount pad of blackboard.
