Abstract
The utility model provides a multifunctional blackboard, comprising a net writing surface inlaid in a frame; a back cover plate arranged at the backside of the frame, an electromotor fixed in the back cover plate, a belt pulley arranged at the four corners of the back cover plate, a transmission belt connected with the electromotor after crossly wound the belt pulley; an eraser clinging to the writing surface, with both ends fixed on the transmission belt, an electric button fixed on the two sides of the lower frame to control the eraser, a plurality of knightheads arranged between the upper and the lower blackboard frames, and a drawer-type chalk dust collection box arranged at the bottom of the blackboard. When in use, the black mental fine net surface can efficiently prevent the reflection of the blackboard and make writing more fluent. The electric eraser saves labor and improves the efficiency of manual blackboard wiping, efficiently solves the dust pollution problem by the centralization collection to the chalk dust, and has the advantages of simple structure and convenient usage.
Description
Technical field
The utility model relates to a kind of multi-functional blackboard.
Background technology
Blackboard is an instrument commonly used in teaching and the office, but in use exists many shortcomings.Usually we impart knowledge to students the blackboard writing surface of usefulness exist reflective, write slack problem.Manually erasing the board, not only efficient is low, and the eminence less than blackboard is wiped because of of short and small stature by regular meeting often, and the chalk dust that disperses everywhere when erasing the board can cause dust pollution, and health is brought very big harm.
Summary of the invention
The utility model provides a kind of multi-functional blackboard, can effectively solve writing surface write not smooth, reflective, manually low the and chalk dust of efficient that erases the board can't be concentrated and takes in the pollution problem that is caused.
The technical solution of the utility model is as follows: the described writing surface that is embedded in the frame that comprises, and its writing surface is a wire side; Back at frame is provided with back shroud, and motor is installed in the back shroud, is provided with belt pulley at back shroud four jiaos, and driving-belt intersects that the back is connected with motor on the belt pulley; A wiping board device is close on the writing surface, and wiping board device two ends are fixed on the driving-belt, and the lower frame both sides of frame are equipped with the electronic button of control wiping board device, are provided with a plurality of support bars between the upper and lower frames of blackboard frame, and the blackboard bottom is provided with the drawer type chalk dust and collects box.
To improvement of the technical scheme: the support bar between the blackboard upper and lower frames is a triangular prism.
To further improvement in the technical proposal: netted of the blackboard writing surface is the ferrous metal thin net.
Beneficial effect:
Multi-functional blackboard described in the utility model, the ferrous metal thin net can effectively prevent the reflective of blackboard, and can make write more smooth.Electronic wiping board device is not only laborsaving can also to improve the efficient that manually erases the board, and can effectively solve the dust pollution question that chalk dust causes to concentrated the taking in of chalk dust.
