Abstract

The invention provides a multifunctional teaching blackboard, and relates to the field of teaching facilities. The multifunctional teaching blackboard comprises a plate frame, a bottom plate and a push-pull plate surface, wherein three groups of layered fixing grooves are formed in the inner side wall of the plate frame, the bottom plate is fixed inside the plate frame through the fixing grooves,close to the side wall of the frame, on one side of the plate frame, a touch screen is fixed at the upper part of the middle bottom plate of the plate frame through the middle fixing groove, a gap isreserved between the touch screen and the bottom plate, magnetic drawing plates are arranged in the plate frame on the two sides of the touch screen, a sliding rail is transversely arranged in the fixing grooves in the plate frame on the upper portion of the touch screen, the push-pull plate surface is provided with two blocks which are arranged on the plate frame through the sliding rail, and a computer host is installed inside the hollow structure of the lower frame of the plate frame. According to the multifunctional teaching blackboard, the touch screen is installed in the middle of the plate frame, and the magnetic drawing plates are installed on the two sides of the touch screen, so that a traditional chalk plate is replaced, dust cannot be generated in the writing process, and the blackboard is environment-friendly and convenient to use.

Description

technical field [0001] The invention relates to the field of teaching facilities, in particular to a multifunctional teaching blackboard. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be repeatedly written with chalk. The board surface is hard and is mostly used for teaching. Blackboards are generally made of wood or frosted glass, and can be written on with specific writing materials such as chalk. Mostly black, dark green, white or beige. [0003] Traditional classrooms use computer projection as a blackboard during teaching. During the projection process, due to the influence of light factors and projection equipment, the imaging effect is likely to be unclear, which is not conducive to teaching. In addition, when using traditional blackboards, chalk is required Writing on the blackboard, the dust produced by chalk is likely to cause occupational disease hazards, and ...
