Abstract

The utility model relates to an anti-reflection blackboard. An original complete blackboard is uniformly divided into two pieces. Small wheels are arranged below the blackboards at both sides. The middle blackboard is fixed on a wall surface. A fixed rail is arranged at the lower sides of the blackboards so that the blackboards at both sides can freely move to the middle position on the rail. The anti-reflection blackboard has simple structure and low manufacturing cost. When a teacher writes on the blackboards at both sides, in the case of excessively strong reflection light outside, when students do not see content written on the blackboards due to light reflection, the blackboards at both sides can be slided to the middle position, so that the reflection light is eliminated and the students sitting at both sides can see the contents written on the blackboards clearly, thereby improving the learning effect of the students in class and the teaching quality of the teacher.

Description

Reflection prevention blackboard

Technical field

The utility model relates to a kind of reflection prevention blackboard.

Background technology

At present, school's blackboard commonly used all is fixed blackboard.In the time of at school, be sitting in the student of both sides, classroom, because blackboard reflective light, it is bright especially to understand some blackboard surface, causes teacher to can't see the content avris student of this position writing on the blackboard, thereby has influenced student's listen to the teacher effect and teacher's quality of instruction.

The utility model content

The purpose of this utility model is to provide a kind of anti-reflective blackboard, and that this design has is simple in structure, with low cost, easy to use, be beneficial to teaching.

The utility model for achieving the above object, the technical solution of employing is:

Reflection prevention blackboard is that an original monoblock blackboard is divided into three, installs small wheels below the blackboard of both sides, and a middle blackboard is fixed on the metope.Downside at blackboard is installed trapped orbit, makes the blackboard of both sides can be free to travel to the centre position in orbit.

The beneficial effects of the utility model: this blackboard structure is simple, low cost of manufacture, teacher is when the writing on the blackboard of blackboard both sides, if outside light is too strong, owing to when reflective student can't see the writing on the blackboard content, can slide into the centre position to the blackboard of both sides, thereby eliminate reflective, can make the student who is sitting in both sides also can see writing on the blackboard clearly, improve student's listen to the teacher effect and teacher's quality of instruction.

Fig. 4 is the enlarged drawing of reflection prevention blackboard left view Fig. 2 bottom

Fig. 5 is the right-hand member enlarged drawing of track vertical view Fig. 3 of reflection prevention blackboard

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 5 the utility model is elaborated.

Reflection prevention blackboard, comprise a fixed plate 4 and two active plates 2, groove 7 is arranged at the top of blackboard, groove 3 is arranged at the bottom, both sides have 1, two active plate 2 of frame can slidably reciprocate on track 6 by small wheels 5, and track 6 is fixed on groove 3 inside, fixed plate is fixed on the holddown groove 8, can not slidably reciprocate.

During use, teacher is when the writing on the blackboard of blackboard both sides, if outside light is too strong, because when reflective student can't see the writing on the blackboard content, can slide into the centre position to the blackboard of both sides, thereby eliminate reflectively, can make the student who is sitting in both sides also can see writing on the blackboard clearly, improved student's listen to the teacher effect and teacher's Teaching Quality.

Claims

1. reflection prevention blackboard, it is characterized in that: be that an original monoblock blackboard is divided into three, below the blackboard of both sides, install steamboat, a middle blackboard is fixed on the metope, downside at blackboard is installed trapped orbit, makes the blackboard of both sides can be free to travel to the centre position in orbit.
