Abstract
The utility model provides an electronic type economic management learns teaching device, includes the frame of rectangle, characterized by: the base frame in the front side inlay and have the panel, be provided with the multiseriate LED lamp array of multirow on this panel, respectively be equipped with an inductive switch on each LED lamp next door, this inductive switch respectively establishes ties on the circuit of each LED lamp to be connected with DC power supply's both ends. DC power supply's return circuit on establish ties and have switch and power indicator. The LED lamp be three -colour LED, inductive switch passes through control circuit and is connected with three -colour LED's three electrode and common port respectively. The beneficial effects of the utility model are that: arbitrary any LED lamp can be lighted through pressing inductive switch, stock tendency curve is drawn out, it is convenient, swift, the transform is easy, has saved a large amount of pen association's time, has increased the time of explanation.
Description
Technical field
The utility model relates to a kind of electronic type science of economic management instructional device, replaces mechanical device.
Background technology
Saying that stock class hour all needs curve plotting figure at every turn, after several curves drawn by one piece of blackboard, just there will be more random phenomenon, compare and be not easy to see clearly, and every class is being lost time all very much, incuring loss through delay teaching process, reduce lecture time.In order to solve the problem, occur a kind ofly adopting the science of economic management instructional device of physical construction curve plotting (if Authorization Notice No. is the utility model patent of CN204066501U), its shortcoming is complex structure, uses inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of electronic type science of economic management instructional device, connects the complex structure that prior art exists, inconvenient problem with use.
The technical solution adopted in the utility model is: a kind of electronic type science of economic management instructional device, comprise the frame of rectangle, it is characterized in that: the front side in described boundary frame area is inlaid with panel, this panel is provided with the LED array of many row's multiple rows, an inductive switch is respectively provided with on each LED side, each series connection this inductive switch on the circuit of each LED, and be connected with the two ends of direct supply.
The loop of described direct supply is in series with power switch and power light.
Described LED is three-color LED, and inductive switch is connected with three electrodes of three-color LED and common port respectively by control circuit.
Link is provided with on the top of described frame.
The beneficial effects of the utility model are:
Can be lighted the LED of any point by touch press sensing inductive switch, draw out shares changing tendency curve map, convenient, fast, conversion easily, saves a large amount of Pen Association's time, adds the time of explanation.
Accompanying drawing explanation
Fig. 1 is overall frontside structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
See Fig. 1 and Fig. 2, a kind of electronic type science of economic management of the utility model instructional device, comprise the frame 1 of rectangle, it is characterized in that: the front side in described boundary frame area 1 is inlaid with panel 3, this panel 3 is provided with the array of the LED 4 of many row's multiple rows, respectively be provided with an inductive switch 5 on each LED 4 side, each series connection this inductive switch 5 on the circuit of each LED 4, and be connected with the two ends of direct supply 10.Direct supply 10 can adopt battery, also can adopt power supply adaptor mains-supplied.
The loop of described direct supply 10 is in series with power switch 8 and power light 9.
Link 2 is provided with, for hanging over body of wall or support on the top of described frame 1.
LED 4 described in the utility model can also adopt three-color LED, and inductive switch 5 is connected with three electrodes of three-color LED and common port respectively by control circuit.Often press an inductive switch 5, namely LED 4 limit converts a kind of color (circulation variable color, routine techniques).Like this, the curve of three different colours can just be drawn.
Using method of the present utility model is, after hanging up properly, and power-on switch 8, power light 9 is lighted; Select the inductive switch 5 on corresponding LED 4 side of pressing according to curve shape, corresponding LED 4 is lit, and the multiple LED 4 be lit form the curve needed.
