Abstract

The invention discloses a teaching blackboard with a large amount of writing, comprising a soft blackboard body, a hard backing board, an upper support roller and a lower support roller. On the surface, the back of the front layer of the soft blackboard body is a hard backing board. The soft blackboard body also includes a writing storage board surface. The writing storage board surface is located between the front layer and the rear layer of the soft blackboard body. The writing storage board The surface of the soft blackboard is formed by multiple reversing rollers to fold the cloth surface of the soft blackboard body for many times. One side of the lower support roller is provided with a hand wheel for rotating the lower support roller; the support of at least one reversing roller is adjustable. The sliding support, the slidable support is connected with the tension spring, the invention can avoid the loose and incoherent teaching and writing content, and can greatly increase the reserved content of the board surface.

Description

technical field [0001] The invention relates to the field of school teaching appliances, in particular to a teaching blackboard with a large amount of writing. Background technique [0002] In teaching, teachers often need to use chalk to write on the blackboard.
