Description
Technical field
The utility model is related to a kind of display board more particularly to a kind of differential equation display boards.
Background technology
The differential equation refers to the equation of the relationship between the derivative and independent variable of description unknown function.The Xie Shiyi of the differential equation
The function of a Composite Equations.And in the algebraic equation of elementary mathematics, solution is constant value.
The application of the differential equation is very extensive, can solve the problems, such as many related with derivative.Many is related to becoming in physics
The kinematics of power, dynamics problem, as air resistance be velocity function falling the problems such as, can much use differential side
Journey solves.In addition, the differential equation has application in fields such as chemistry, engineering science, economics and demographics.
Multimedia teaching display board in teaching is powerful, disclosure satisfy that needed for teaching, can show various complexity
Differential formulas, but expensive, high energy consumption, maintenance cost is high, and ordinary university will not use such equipment, due to differential
Formula comparison is complicated, and traditional chalk-writing is cumbersome, easily generates a large amount of dust, now lacks a kind of simple in structure, appearance
The display board easily shown.
Utility model content
In order to solve above-mentioned prior art problem, the utility model provides a kind of differential equation display board, can improve
Above deficiency.
The utility model is related to a kind of differential equation display board, including showing plate body, the display board body surfaces point
For sign field and show area, displaying plate body top both sides setting connects quarter butt, described connection quarter butt one end and display board
Main body is hinged, and one of the other end and thin steel rope is fixedly connected, and the other end of the thin steel rope is connect with link, the thin steel rope
On be provided with a flexible group box, the symbol area is pasted with patch, with ordinary differential equation symbol, the symbol on the patch
Area and show area surface, which all contain, to be magnetic.
Further, the flexible group of box includes magnetic upper cartridge body and magnetic lower box body, and there are recessed between their contact surfaces
Slot is provided with elastic rope in the groove, and described elastic string one end connect with magnetic upper cartridge body concave surface, the other end under magnetism
Box body concave surface connects.
Further, on the patch withCosx, sinx, dx, x, y, z, ∫ ,+,-,=, ex, c.
Further, contain irony in the patch, its one jiao of tilting, raised portion is with patch other parts not same
In one plane.
Further, displaying plate body back side lower edge is arranged in parallel with horizontal stripe.
The utility model is novel in design, simple in structure, is capable of the quick aobvious of real display board using the pattern of combination adhesive sheet
Show function, due to not needing to writing complexity symbolic differential equation repeatedly, the use of chalk can be reduced.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is suspended on schematic diagram on wall for display board.
Fig. 3 is paster structure schematic diagram.
A kind of service condition figure of Fig. 4 display boards.
1 displaying plate body, 2 sign fields, 3 show areas, 4 patches, 5 connection quarter butts, a 6 flexible group boxes, 61 magnetic upper cartridge bodies,
62 magnetic lower box bodies, 7 thin steel ropes, 8 links, 9 elastic ropes, 10 horizontal stripes.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of differential equation display board, including showing plate body 1,1 surface of the displaying plate body
It is divided into sign field 2 and show area 3, in 1 top both sides of displaying plate body setting connection quarter butt 5, described connection 5 one end of quarter butt and exhibition
Showing that plate body 1 is hinged, the other end is fixedly connected by one of thin steel rope 7, is connect in the other end of thin steel rope 7 with link 8,
It is provided with a flexible group box 6 among thin steel rope 7, installation when hangs over entire display board on metope by link 8；In symbol
2 domain of area is pasted with patch 4, contains irony in patch 4, as shown in figure 3, one jiao of tilting of patch 4, raised portion and patch 4 are not
In the same plane, horizontal stripe 10 is arranged in parallel in displaying 1 back side lower edge of plate body, horizontal stripe 10 and wall when display board is installed
Face contacts, and horizontal stripe 10 plays supporting ＆ stablizing to display plate body 1.
With ordinary differential equation symbol on the patch 4, such asCosx, sinx, dx, x, y, z, ∫ ,+,-,
=, ex, c.The sign field 2 and 3 surface of show area, which all contain, to be magnetic.It should be noted that the symbol on patch 4, general
The symbol of ordinary differential equation, such as differential equation of first order symbol and second order differential equation symbol pass through different 4 energy of combination adhesive sheet
Enough form the different differential equations.
The flexible group of box 6 includes magnetic upper cartridge body 61 and magnetic lower box body 62, and there are groove, institutes between their contact surfaces
It states and elastic rope 9 is provided in groove, described 9 one end of elastic rope is fixedly connected with magnetic upper cartridge body 61, the other end and magnetism
Lower box body 62 is fixedly connected.
When display board uses, corresponding symbolic differential equation can be selected in sign field 2, so according to teaching needs
After be pasted onto in show area 3 (as shown in Figure 4), since one jiao of patch 4 has and tilts, hand pinches raised portion and is easy to patch
Piece 4 is moved.
After display board is fixed on wall, flexible group box 6, magnetic upper cartridge body 61 and magnetic lower box body 62 can also be adjusted
By it is magnetic together when, the shortening of thin steel rope 7, the spacing of display board and link becomes smaller, on the suspension height of display board
It is mobile, after magnetic upper cartridge body 61 is separated with magnetic lower box body 62, due to being provided with elastic rope 9 in groove, at this point, thin steel
The length of rope 7 increases, and the spacing of display board and link becomes larger, and is moved under the suspension height of display board.
The utility model is novel in design, simple in structure, is capable of the quick aobvious of real display board using the pattern of combination adhesive sheet 4
Show function, due to not needing to writing complexity symbolic differential equation repeatedly, the use of chalk can be reduced.
