Abstract
The utility model discloses a non-steel blackboard convenient for map hanging, relating to a special blackboard for solving the problems of non-steel blackboard for map hanging or using magnetic teaching aids. The back side of the non-steel blackboard is provided with an iron sheet or a magnetic block, the relevant position of the front side of the non-steel blackboard is marked with the position of the iron sheet or the magnetic block by a color similar to but different from that of the surface of the blackboard, and the marking signs can be dashed lines, real lines, dots, etc. The blackboard solves the problem of using non-steel blackboard to hang charts and using magnetic teaching aids.
Description
The utility model relates to a kind of non-steel blackboard of being convenient to school wall map.
The many kinds of using in the teaching of blackboard have wooden blackboard, bamboo matter blackboard, synthetic resin blackboard, metal blackboard, Glass blackboard or the like.The metal blackboard divides steel blackboard and other non-ferrous metal blackboard again.In a word, various types of blackboards can be summarized as steel blackboard and non-steel blackboard.Can use the magnetic teaching aid for the rigidity blackboard, also available magnetic nail " wall chart, very convenient in teaching; But not the steel blackboard is then insensitive to the magnetic teaching aid, also can't use " magnetic nail " wall chart, and this is the weak point that is extensive use of non-steel blackboard at present.
The purpose of this utility model provides a kind of non-steel blackboard of being convenient to wall chart, also can use the magnetic teaching aid.
Technical solution of the present utility model is: on the basis of non-steel blackboard, at its back side iron plate or magnetic patch are set, use color close with the blackboard surface color and don't that be same as the blackboard surface color to mark the position of back side iron plate or magnetic patch in its positive relevant position, so both be convenient to seek its position, and do not influenced again and write and vision.But its mark with dashed lines, solid line or some note all can.Its iron plate or magnetic patch are fixed in the blackboard back side, and available stickup, rivet clasp or way such as inlay realize.
Owing to adopted technique scheme, make the wall chart of non-steel blackboard become possibility with using the magnetic teaching aid, and also very convenient.
Description of drawings:
