Detailed description of the invention
The utility model is elaborated preferred embodiment below in conjunction with accompanying drawing.
A kind of blackboard for education, comprise blackboard body, the napex of described blackboard body is provided with chute, pulley is provided with in described chute, described pulley is fixedly connected with support bar, described support bar is provided with locating piece, described support bar passes and is slidably connected with it from locating piece, described locating piece is provided with altitude location button, described locating piece bottom is provided with the cored slab of lateral opening, bottom, described cored slab surface is provided with supporting plate, described cored slab surface is also provided with two transparent fixed bands of elasticity from top to bottom, spring is provided with in described cored slab, the termination of described spring is provided with and pushes away bar, the Ban Kou both sides of described cored slab are provided with slot, plate is provided with in described slot, describedly also comprise base, described base lower surface is provided with runner, described base upper surface is provided with expansion link termination described in expansion link and is provided with blackboard body bottom described in external screw thread and is provided with the sleeve pipe matched with external screw thread, described base avris is provided with blind hole, disc spring is provided with in described blind hole, described disc spring is connected with movable axis, described movable axis both sides are provided with flexible card, inserted lamp socket in described movable axis connects, described lamp socket is provided with shot-light.Teaching lattice chi, grid plate, set square is provided with in described cored slab.
During use, not only teacher can with two transparent fixed band textbooks of elasticity, and transparent fixed band is to fix textbook simultaneously but also do not affect teacher and see word, like this on blackboard during writing Chinese characters, teacher just need not frequently turn one's head to consult bookish content, decreases the damage to teacher's cervical vertebra; Have spring to be connected with in cored slab and push away bar, upwards pull plate along chute, teaching aid oneself ejects.Take so that do not spend dais when teacher's book uses, alleviate the workload of teacher, provide the classroom teaching efficiency of teacher.Supporting plate can be put blackboard eraser and teacher's pointer use.Floor installation runner Convenient blackboard moves, expansion link and external screw thread match sleeve pipe play blackboard lifting, conveniently be sitting in student viewing below, when using shot-light, by the flexible card of movable axis both sides, movable axis is stuck in outside blind hole, is upwards rotationally connected the lamp socket of movable axis, can throw light on, flexible card when not using on contraction movement axle, puts into blind hole by shot-light.Shot-light is to space, and color, actual situation impression is all very strongly unique, is conducive to the eyes protecting student.
The utility model is reasonable in design, multiple functional, effectively can either support textbook, again can teaching aid easy to use, effectively raises the classroom teaching efficiency of teacher.
