Abstract

The utility model relates to a blackboard eraser comprising a blackboard and a connecting frame, vertical chutes are respectively formed at the left and the right sides of the blackboard, the left and the right ends of the connecting frame are respectively embedded in the chutes for connection; a cross shaft at the bottom side of the connecting frame is connected with an erasing frame, the erasing frame adopts a three-dimensional structure with a side opening, two transverse partition boards are arranged in the erasing frame to divide the erasing frame into three parts, namely an upper part, a middle part and a lower part, while a dry erasing pad, a semi-dry erasing pad and a wet erasing pad are respectively inserted in the upper, the middle and the lower parts. When in use, a user turns over the erasing frame to ensure that various erasing pads are in contact with the surface of the blackboard, then the erasing frame is moved up and down along the chutes and the erasing pads are utilized to erase the blackboard, and the erasing task can be completed by once sliding; furthermore, the different erasing pads can play different erasing effects, thereby avoiding dust pollution. The blackboard eraser has the advantages of reasonable structure, simple operation, high efficiency, high speed, convenience, practicality, etc.

Description

Device erases the board

Technical field

The utility model relates to a kind of burnisher, especially a kind of blackboard wiping instrument.

Background technology

As everyone knows, blackboard eraser is a most important blackboard eraser wiping instrument in the present school instruction.But present blackboard eraser volume is less, needs wiping repeatedly during blackboard wiping, the waste plenty of time, and also dust floats in air in the wiping process, causes the air dirt, and it is healthy to influence teachers and students.In order to address the above problem, we provide a kind of slidingtype wiping instrument, but the quick blackboard wiping of large tracts of land, and reduce and pollute.

Summary of the invention

The purpose of this utility model provides a kind of device that erases the board, and is used to solve problems such as normal blackboard wiping instrument elapsed time, wiping effect difference.

For achieving the above object, the utility model device that erases the board comprises blackboard and link, offers vertical slideway respectively at the right and left of blackboard, and the two ends, the left and right sides of link embed in the slideway respectively and connect; Connect wiping stand at link base transverse axis, described wiping stand is the side opening stereochemical structure, and opening surface is towards blackboard, in two lateral partitions of the inner installation of wiping stand, wiping stand is divided into upper, middle and lower three parts, in upper, middle and lower three parts, assigns dry and comfortable cleaning pad, half-dried cleaning pad and moist cleaning pad respectively.

After adopting said structure, during use, user's wiping stand that overturns, guarantee that various cleaning pads contact with blackboard surface, move up and down wiping stand along slideway then, utilize the cleaning pad blackboard wiping, just can finish the wiping task by once slip, and different cleaning pads can bring into play different wiping effects, avoid dust pollution.

Compared with the prior art, the beneficial effects of the utility model are: rational in infrastructure, easy and simple to handle, efficiently quick, convenient and practical, blackboard wiping improves efficiency of teaching fast.
