Manual integral dry wiping writing board

Abstract

The invention discloses a manual integral dry wiping writing board, and relates to the technical field of writing boards. The manual integral dry wiping writing board comprises a writing board body and further comprises an integral board wiper and a sliding device for the board wiper to move left and right, wherein the integral board wiper corresponds to the writing board body in width. The sliding device comprises a transverse moving mechanism. The transverse moving mechanism comprises transverse linear slide rails arranged on an upper frame and a lower frame of the writing board body respectively. Transverse sliding blocks are in sliding fit with the transverse linear slide rails. The two ends of the board wiper are fixedly connected with the upper transverse sliding block and the lower transverse sliding block respectively. The board wiper is pushed and can move left and right in the length direction of the writing board body, and chalk traces on the board face of the writing board body are erased away. The integral board wiper with the width equal to that of the board face of the writing board is adopted, accordingly, the integral wiping of the whole board face can be achieved, wiping is fast, time and labor are saved, flying dust is greatly reduced, and the teaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of writing boards, in particular to a manual integral dry-erase writing board. Background technique [0002] At present, most of the wiping boards on the market are directly wiped by ordinary small board erasers. When wiping the entire board surface of a large area, the wiping amount is relatively large, and the wiping efficiency is low. At the same time, the chalk dust generated during the wiping process is serious. , bringing extremely adverse effects on the health of teachers and students in the front row. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manual integrated dry-erase writing board, which uses an integrated eraser with the same width as the writing board surface, which can realize the overall wiping of the entire board surface, wipe quickly, save time and effort, and greatly reduce Dust flying, improve teaching efficiency.
