Abstract

The utility model relates to the technical field of teaching appliances, in particular to a novel teaching board. The novel teaching board comprises a blackboard and a blackboard eraser. An upper frame and a lower frame of the blackboard are respectively provided with a groove, the blackboard eraser is in a long bar shape, the two ends of the blackboard eraser are respectively provided with a pulley, and the pulleys are inlaid into the grooves. A dust suction hood is arranged on the periphery of the blackboard eraser. A rotating shaft is arranged on the blackboard edge of the lower groove, a telescopic rod is arranged on the rotating shaft in a sleeved mode, a spring is fixedly arranged in the telescopic rod, and a pull ring is arranged at the tail end of the telescopic rod. The novel teaching board has the advantages of being simple in structure, convenient to use, large in wiping area of the blackboard eraser, saving in time and labor, capable of improving work efficiency, and capable of preventing dust from scattering in all directions and flying upwards in the blackboard wiping process due to the arrangement of the dust suction hood, thereby protecting the good health of teachers and students and lowering the drawing difficulty of teachers.

Description

A kind of new teaching plate

Technical field

The utility model relates to teaching aid technical field, is specifically related to a kind of new teaching plate easy to use.

Background technology

Along with the raising of scientific and technological progress and teaching requirement, the requirement of teaching stationery is also being improved, at present, the blackboard that school of China is used is still take traditional blackboard as main, the wiping method of this blackboard is hand-held blackboard eraser, wiping repeatedly on blackboard, the area of the each wiping of blackboard eraser is little, with traditional blackboard eraser blackboard wiping, not only time-consuming but also require great effort, and traditional blackboard eraser, dust from flying after nuzzling up, the respiratory tract of the Faculty and Students that erase the board is caused to very large impact, be unfavorable for that people's is healthy, teacher holds on the other hand fixing ruler high in the time drawing, one hand-held chalk mapping, very trouble of operation like this, waste time and energy, increase work difficulty to teacher.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, and a kind of new teaching plate easy to use is provided.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of new teaching plate described in the utility model, comprise blackboard and blackboard eraser, the upper and lower frame of blackboard is respectively provided with a groove, and blackboard eraser is elongated, and the two ends of blackboard eraser are respectively provided with a pulley, pulley is embedded in groove, described blackboard eraser is arranged with dust shield outward, and the blackboard edge of low groove is provided with rotating shaft, is arranged with expansion link in rotating shaft, in expansion link, be installed with spring, the end of expansion link is provided with draw ring.

As preferably, described dust shield is for to make semicircular arc rubber peel by rubber.

As preferably, described dust shield bottom is provided with pore.

Adopt after said structure, the utility model beneficial effect is: simple in structure, easy to use; blackboard eraser erasing area is large, time saving and energy saving, increases work efficiency; arrange and when dust shield makes to erase the board, avoided dust to scatter flying upward, protected the healthy of teachers and students, alleviated teacher's difficulty of drawing.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
