Abstract

The utility model discloses a novel blackboard capable of automatically erasing chalk dust by switching, which belongs to the technical field of teaching appliances. The blackboard consists of a blackboard surface, pulleys, an inner guide rail, an outer guide rail, a handle and hairy brushes, wherein the blackboard surface consists of four glass boards with the same size; a pair of pulleys is respectively arranged on the upper side and the lower side of each glass board; the pulleys are installed inside the guide rails fixed on the upper side and the lower side of the blackboard; a hairy brush of which the width is equal to that of the blackboard is arranged between every two glass boards; a dust box is arranged below the hairy brush; and each hairy brush is connected with a manual adjusting device. The blackboard overcomes the defects that the blackboard erasing in the prior art is high in labor intensity and low in speed and generates much dust, so that the automatic erasing function is realized; and part of the contents on the blackboard is erased or kept, so that the flexibility and freedom for the layout of a teacher are improved.

Description

Novel changeable automatic erasing blackboard
Technical field
The utility model relates to a kind of educational aid; In particular; Be particularly related to a kind of novel changeable automatic erasing blackboard, the utility model has overcome blackboard eraser and has removed the shortcoming that labour intensity is big, speed is slow, dust is many, has realized automatic erase feature; And the part of plate face content is wiped or is kept, and has improved the flexibility ratio and the free degree of teacher's plate face design greatly.
Background technology
Blackboard is the important media of knowledge dissemination in the daily teaching work, and present blackboard pattern also is varied, can be divided into Glass blackboard, cement blackboard by the material that constitutes; Be divided into fixed and portable by manner; Be divided into automation formula, semi-automatic formula, non-automaticization formula by automaticity.But for a long time, wiping of blackboard all is manual erase, like this since, not only labour intensity is big, speed is slow, and can produce serious dust pollution, serious harm Faculty and Students healthy.Therefore, the dust pollution of blackboard is a problem demanding prompt solution.
