Description
Technical field
The utility model belongs to teaching field, relates to a kind of teaching aid, especially economics and management science teaching aid, specifically a kind of economic management column diagram exhibiting device.
Background technology
The teacher of economics and management science is in the process of teaching; often can run into statistics and the contrast of some data; and the form of only giving an oral account is told about to students; be difficult to understand and analyze; therefore instructors all needs drafting column diagram carry out displaying to the statistics of data and contrast and particularly separate; it is the hand drawn that teacher carries out repeatedly on blackboard that traditional column diagram draws mode; can be wiped after explanation terminates; cannot retain; and also need when needing to repaint; with the addition of burden to the teaching of teacher, and incur loss through delay the classroom limited time.
Summary of the invention
For solving in teachers' instruction process the hand drawn column diagram needed repeatedly, and can not retain, burden is with the addition of to the teaching of teacher, and incur loss through delay the problem of time in classroom, the utility model proposes a kind ofly does not need loaded down with trivial details hand drawn, and the column diagram exhibiting device of Reusability between column diagram that can be different, its concrete technical scheme is as follows:
A kind of economic management column diagram exhibiting device, comprise backboard and be fastened on the front panel on backboard, on described front panel, longitudinally having promise does window parallel to each other, window place connects light-passing board, backboard is provided with LED lamp panel with each window opposite position, in described LED lamp panel, each LED feeder ear of horizontal a line is in parallel, longitudinally do not connect, the feeder ear of every a line connects wire, each wire order be arranged on contact plate, contact plate is fixed on backboard, contact plate contacts with power supply board and power supply board can at contact plate surface sliding, power supply board is connected with power circuit, power circuit comprises accumulator, power supply board is connected with insulated slide bar, the longitudinal length slip gap identical with window longitudinal length is offered near window corresponding on front panel, slip opening position is provided with scale value, described insulated slide bar is through slip gap, insulated slide bar is in the connection Handheld Division, one end outside front panel, the side relative with window, Handheld Division connects transparent sign slot.
Described backboard top middle portion is connected with carry hand, and carry hand stage casing is provided with annular link.
Described window is all in front panel upper part, and front panel lower part is provided with blackboard.
The beneficial effects of the utility model: in use, teacher not only can drive power supply board by slip insulated slide bar, power supply board is connected by the conductive contact with diverse location on contact plate thus with the LED of different rows in LED lamp panel, and recycling power supply board is connected with power circuit thus is that the LED of different rows is powered; And then manipulate the bright height of each window place LED lamp panel, thus show corresponding column diagram data; And can by indicating in slot the data attribute novel markings inserting this cylindricality and indicate, be connected on insulated slide bar owing to indicating slot, therefore while slip insulated slide bar, indicate slot can along with LED lamp panel bright LED rising and raise, with the bright LED of LED lamp panel reduction and reduce, simultaneously, conveniently the moving and carrying of this device, set up carry hand, and owing to comprising accumulator in circuit, can also can not for plug or when outdoor in classroom; Consumable quantity is few, structure simply makes cost low, simple to operate easy to use and practical.
Accompanying drawing explanation
Fig. 1 of the present utility modelly faces structural representation;
Fig. 2 is right side of the present utility model combination structural representation;
Fig. 3 is LED lamp panel and contact plate syndeton principle schematic.
In figure: 1-backboard, 2-front panel, 3-window, 4-light-passing board, 5-LED lamp plate, 6-contact plate, 7-power supply board, 8-power circuit, 9-insulated slide bar, 10-slip gap, 11-scale value, 12-Handheld Division, the transparent sign groove of 13-, 14-carry hand, 15-annular link, 16-blackboard.
Embodiment
For the ease of understanding, be further illustrated below in conjunction with Fig. 1-3 pairs of the utility model:
Embodiment 1: a kind of economic management column diagram exhibiting device, comprise backboard 1 and be fastened on the front panel 2 on backboard 1, on described front panel 2, longitudinally having promise does window 3 parallel to each other, window 3 place connects light-passing board 4, light-passing board 4 can the light of effective printing opacity LED lamp panel 5 while protection LED lamp panel 5, so that student can see the bright height of LED lamp panel 5 clearly; Backboard 1 is provided with LED lamp panel 5 with each window 3 opposite position, in described LED lamp panel 5, each LED feeder ear of horizontal a line is in parallel, longitudinally do not connect, the feeder ear of every a line connects wire, each wire order be arranged on contact plate 6, when that is powering to a wire on contact plate 6, LED lamp panel 5 only have a line LED bright; Contact plate 6 is fixed on backboard 1, and contact plate 6 contacts with power supply board 7 and power supply board 7 at contact plate 6 surface sliding, in order to better make power supply board 7 have slip on contact plate 6, can arrange chute, so that the slip of contact plate 6 on contact plate 6; Power supply board 7 is connected with power circuit 8, and power circuit 8 comprises accumulator, sets up accumulator and device can be made to use when not powering environment; Power circuit 8 provides electric power for power supply board 7, thus makes power supply board 7 can provide electric power for LED lamp panel 5; Power supply board 7 is connected with insulated slide bar 9, the longitudinal length slip gap 10 identical with window 3 longitudinal length is offered, so that teacher can to slide the line number that power supply board 7 determines that in LED lamp panel 5, LED is bright by manipulating insulated slide bar 9 outside front panel 2 near window 3 corresponding on front panel 2; In order to improve operation of teacher precision, slip gap 10 place is provided with scale value 11; Described insulated slide bar 9 is through slip gap 10, and insulated slide bar 9 is in the connection Handheld Division, one end 12 outside front panel 2, handled easily; The side relative with window 3, Handheld Division 12 connects transparent sign slot 13, play labeled effect, simultaneously because transparent sign slot 13 is connected on Handheld Division 12, thus make the designation card placed in transparent sign slot 13 can clock point to LED in LED lamp panel 5 the position of bright height.
Embodiment 2: further, conveniently move and carry, described backboard 1 top middle portion is connected with carry hand 14, in addition, in order to can effectively conveniently hang when being not easy to place, carry hand 14 stage casing is provided with annular link 15.
Embodiment 3: further, when power supply board 7 adopts copper coin or other plate of conductive material of hard, because it can not be effectively curling and stretch out, therefore it needs to take portion, therefore the longitudinal length value of front panel 2 will approximate greatly the twice of window 3 longitudinal length value, in order to not cause the waste of position and material, described window 3 is all in front panel 2 upper part, front panel 2 lower part is provided with blackboard 16, this does not only cause waste, and be more convenient for teacher to carry out detailed analysis and explanation to data, and by analysis with say that solution preocess is write on blackboard 16, or other guide is write on blackboard 16, it is worth mentioning that, this position also can arrange clock or miscellaneous part, in addition also power supply board 7 can be designed to the conductive material bent and stretched of similar clockwork spring structure, this just no longer needs this device to lengthen.
