Description

Interactive blackboard of angularly adjustable

Technical Field

The utility model belongs to the technical field of the teaching equipment, in particular to interactive blackboard of angle-adjustable formula.

Background

The blackboard is not particularly a black board, but is a plane which can be repeatedly written in the traditional sense, and the board is hard and is mainly used for teaching. Along with the development of the technology, the electronic blackboard gradually appears, the existing electronic blackboard cannot be combined with the traditional blackboard for integrated teaching, the single electronic blackboard or the blackboard are limited in use, the adjustment and the expansion of the writing area of the blackboard are not convenient, although the electronic blackboard is popularized, the traditional blackboard writing blackboard still generally exists in class, the blackboard is generally made of wood boards, ground glass and the like, and specific writing materials such as chalks can be used for writing on the blackboard. Mostly black, greenish black, white or beige.

The traditional blackboard is fixed on the wall surface when writing, the blackboard can only face the student when the teacher writes, after the teacher writes, the blackboard writing area of the panel is limited, and the blackboard writing can only be erased and written with other contents after the student finishes reading; however, some content is not convenient for teachers to explain after being erased, so that certain limitations exist. And the traditional blackboard is inconvenient for students to interactively communicate with teachers when the teachers write on the blackboard. In addition, the panel with an unadjustable angle wastes a lot of physical strength when writing due to long-time writing.

Some blackboards are configured to be capable of writing on both sides and to rotate around a horizontal middle shaft (for example, a blackboard of patent No. CN 94219600.7), but when a single blackboard is used for writing on both sides, the rotation angle of the blackboard around the horizontal middle shaft of two front and rear users can only be used by one person, and the other person can cause writing obstacle. And this kind of structure can cause the typeface to invert after rotating 90 degrees around horizontal jackshaft the blackboard of side around the blackboard writing back, need just can not make the typeface take place to invert the direction with whole device when mr and student's interactive communication, and is very hard during the use.

In order to solve the problems, the angle-adjustable interactive blackboard with the angle-adjustable panel can be used for writing on both sides.
