Abstract

The invention discloses a blackboard with multiple combination types. The blackboard comprises a frame, wherein a first movable plate and second movable plates which can move in the front-back direction are arranged in the frame, the second movable plates are located on the two sides of the first movable plate, the outer surface of the first movable plate is flush with the outer surfaces of the second movable plates, the second movable plates on the two sides can be close to each other or far away from each other, push plates are arranged on the back surfaces of the second movable plates, the push plates are hinged to the frame, and the push plates are rotated to drive the second movable plates to rotate towards the first movable plate. According to the blackboard, the first movable plate capable of moving in the front-back direction is arranged, so that the first movable plate and the second movable plates can be located on the same plane, and writing of a teacher is facilitated; the movable and rotatable second movable plates are arranged, so that writing of the teacher is facilitated, the physical waste of the teacher is reduced, the influence of light reflection can be reduced, and the learning quality of students is improved; and the structure is simple and reasonable, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a blackboard with multiple combinations. Background technique [0002] Most of the existing blackboards for teaching are divided into two types, one is fixed, and the other is composed of two mutually moving blackboards. The first type has a smooth surface of various combination types, which is convenient for overall Writing, but due to reflections, students sitting on the far side of the classroom often cannot see the content on the blackboard clearly, which affects students' learning. Moreover, the size of the blackboard is long, and the teacher needs to walk back and forth when writing on both sides of the blackboard, which increases the teacher's The physical strength of the blackboard reduces the teaching efficiency; the advantage of the second type of blackboard is that the teacher only needs to move two blackboards to write on both sides of the edge of the black...
