Abstract

The utility model relates to a novel blackboard, comprising a board surface in a rectangle structure whose two short edges are respectively in rotation shaft connection with the small board surface. An elongated lower opening box is arranged on top of the board surface. A motor and a rotation shaft are arranged in the box. The rotation shaft extends from the motor. The power cord of the motor extends out of the box. A shielding cloth is wound on the rotation shaft. A suspension loop is arranged at the bottom end of the shielding cloth. A hook is movably connected with the board surface bottom end. A flat mirror is arranged on top of two small board surfaces. People can adjust the angle between two small board surfaces based on the requirement, thus avoiding the light interference to the board surface, facilitating the students to view the blackboard and facilitating the teacher to observe the students when writing on the blackboard through the flat mirror on the small board surface. When shielding parts of questions, the shielding cloth is pulled down for covering the board and the hook is connected with the suspension loop. After using, the power is on, the motor drives the shaft to rotate and the shielding cloth is retracted. The utility model has simple structure, easy operation, various function and wide applicability.

Description

New blackboard

Technical field

The utility model relates to a kind of teaching aid, especially a kind of new blackboard.

Background technology

In the daily teaching process, blackboard is very important educational aid, and the student understands the content of courses by writing on the blackboard, but because existing blackboard mostly is plate-like structure, can't adjust angle, occur reflective phenomenon easily, have a strong impact on normally watching of student, reduced learning efficiency, and because the needs of teaching, the teacher often needs the shield portions exercise question, existing blackboard structure is fairly simple, favourable help can't be provided, and in order to address the above problem, we provide a kind of new blackboard very necessary.

Summary of the invention

The purpose of this utility model has overcome above-mentioned said deficiency, and a kind of convenient and practical new blackboard is provided.

For achieving the above object, the utility model new blackboard, comprise the plate face, the plate face is a rectangular structure, and its two minor face rotating shaft respectively connects the platelet face, plate face top is provided with strip under shed box body, box body inside is provided with motor and rotating shaft, and rotating shaft is stretched out from motor, and the power line of motor stretches out outside the box body, twine in the rotating shaft and block cloth, block the cloth bottom and be provided with link; Plate face bottom flexibly connects hook, and two platelet face tops are provided with level crossing.

After adopting said structure, people can adjust the angle of two platelet faces and plate face as required, avoid the interference of light to the plate face, and writing on the blackboard convenient for student viewing effectively improves results of learning; The teacher can observe student's situation by the level crossing on the platelet face, the thing of avoiding the student to do and learning to have nothing to do when writing writing on the blackboard; When the needs shielding part divides exercise question, can leave behind blocking cloth, cover plate body, and will link up with link and link to each other, when finishing using, can connect power supply, the driven by motor rotating shaft is rotated, and will block cloth and pack up.

The utility model has the advantages that: simple in structure, easy to use, diverse in function, controllability are strong, applied widely etc.
