Description
technical field:
the utility model relates to a kind of mathematics classroom curve course dedicated presentation device.
background technology:
in mathematics classroom teaching, when study is to curve knowledge such as para-curve hyperbolic curves, teacher needs to paint curve on blackboard, carry out vivid explaining to student specifically, but curve is not easily painted, teacher needs to mark various vector data, needs to expend for a long time, delay classroom progress, now need a kind of can facilitate mathematics teacher on classroom rapid drawing trace and demonstration equipment.
summary of the invention:
the purpose of this utility model is to provide a kind of mathematics classroom curve course dedicated presentation device.
above-mentioned object is realized by following technical scheme:
a kind of mathematics classroom curve course dedicated presentation device, its composition comprises: apparatus main body, hanging platform is provided with above described apparatus main body, described hanging platform is placed with one group of vector identification A.O., described apparatus main body side is provided with controller, described controller is provided with battery and on & off switch, described apparatus main body is provided with translot and vertical slot, one group of LED lamp bead is provided with in described translot and described vertical slot, described apparatus main body arranges Turbogrid plates, described Turbogrid plates are provided with transverse axis vector magnetic support and vertical pivot vector magnetic support, described apparatus main body bottom is provided with rubber bound edge.
described mathematics classroom curve course dedicated presentation device, described hanging platform offers A.O. standing groove, described vector identification A.O. is placed in described A.O. standing groove; Described LED lamp bead is electrically connected with described controller, and described Turbogrid plates can be pulled down from described apparatus main body; Described vector identification A.O. is provided with vector title labeling, described vector identification A.O. and described transverse axis vector magnetic support and described vertical pivot vector magnetic support adaptive.
the beneficial effects of the utility model:
1. can be coordinated with blackboard coboundary by hanging platform when the utility model uses, apparatus main body is hung on blackboard, apparatus main body is provided with Turbogrid plates, accurate reference can be provided to teacher's curve of painting, precisely can be painted curve by the mode of multiple spot line, vector identification A.O. and transverse axis vector magnetic support and vertical pivot vector magnetic support adaptive, can be adsorbed on magnetic support, A.O. posts such as speed, the labeling of the different vector such as time, the variable that teacher can relate to according to curve carries out choice for use, LED lamp bead can be luminous by powered battery, curve is shone clear, after convenient, row classmate also can see clearly.
the utility model structure is simple, and easy to use, each several part parts can be changed, when device breaks down, only need to change the parts broken down, save cost, the rubber bound edge of device body frame bottom can play cushioning effect, anti-locking apparatus be badly shaken in put procedure knock bad.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
