Problems solved by technology

Due to the popularization of multimedia teaching and the wide application of computers and projectors, the space utilization rate in classrooms is very high, and many blackboards are designed too large to easily get in the way, while blackboards are too small, sometimes not enough to write content
The existing blackboards are simple in design, unable to change the volume freely and flexibly, and are not suitable for use in multimedia classrooms

Abstract

The invention discloses a deformable blackboard, and relates to the field of teaching equipment. The deformable blackboard comprises a fixed blackboard which is in the shape of a rectangular plate, wherein a rectangular pulling slot is formed in one side of the fixed blackboard; the bottom of one side, with the pulling slot, of the fixed blackboard is perpendicularly equipped with a support bottom; three layers, without the pulling slot, of the fixed blackboard are covered with a fixed side frame; the top of the fixed side frame is perpendicularly equipped with two ring-shaped lifting rings; the rectangular plate shaped movable blackboard is inserted into the insertion slot of the fixed blackboard; the side surface of the movable blackboard is covered with a movable side frame; and the position, away from center of the one side of the insertion slot of the fixed blackboard, of the movable side frame is perpendicularly equipped with a pulling handle. The deformable blackboard is delicate in design, can freely and flexibly change the size, is free in extension and retraction, is strong in reliability, and is suitable for being used in a multimedia classroom.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to a deformable blackboard. Background technique [0002] The blackboard is a plane that can be repeatedly written with chalk. The board 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. Due to the popularization of multimedia teaching and the wide application of computers and projectors, the space utilization rate in classrooms is very high, and many blackboards are designed too large to easily get in the way, while blackboards are too small to be used for writing content. The existing blackboards are simple in design, unable to change the volume freely and flexibly, and are not suitable for use in multimedia classrooms. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a deformable blackboard, which is ...
