Problems solved by technology

[0002] Most of the existing blackboard mechanisms are fixed blackboards, and there are also push-pull blackboards. The push-pull blackboards mainly use the mechanism of fixed pulleys and ropes, but the transmission of this mechanism is unstable.
In addition, teachers often need to erase the blackboard when teaching, and the chalk dust generated will fly in the classroom, which is a serious threat to the health of teachers and students

Abstract

The invention discloses a novel lift type blackboard capable of changing front and back positions and quickly wiping off dust, which consists of two blackboards, flexible racks, fixed supporting frames, one-way gear mechanisms, a front and back position changing device and a board wiper device, wherein the front sides of the left and the right of the blackboards are provided with the flexible racks, the two side faces of the left and the right of the blackboards are provided with common racks, the fixed supporting frames are provided with the one-way gear mechanisms, and gears and tensioning wheels are arranged between the supporting frames in a crossing manner. The novel blackboard is mainly used for being cooperated with the teaching activities of a teacher, front and back position changing and lift movement of the blackboards are realized, the function of quickly and automatically wiping off dust during lifting is realized, the time of wiping the whole blackboard is saved, the teaching efficiency of the teacher is improved, and chalk dust generated in the wiping process is distributed between the two blackboards without flying in a classroom, so that chronic damage of the chalk dust to the teacher and students is reduced, the teaching environment is improved, and the teaching quality is enhanced.

Description

technical field [0001] The invention belongs to the technical field of teaching appliances, in particular to a new type of blackboard which can quickly erase dust by shifting front and back. Background technique [0002] Existing blackboard mechanism great majority all is fixed blackboard, also has up and down push-pull type blackboard, and up and down push-pull type blackboard mainly adopts the mechanism of fixed pulley and rope, but this mechanism transmission is unstable. In addition, teachers often need to erase the blackboard when teaching, and the chalk dust generated will fly in the classroom, which is a serious threat to the health of teachers and students. Contents of the invention [0003] The object of the present invention is to provide a new type of blackboard with front and rear transposition lift type for quickly erasing dust. [0004] For realizing the above-mentioned purpose of the invention, the technical scheme that the present invention adopts is: [...
