Description
Technical field
The utility model is related to a kind of higher mathematics special-purpose multifunctional curved surface demonstration teaching aid.
Background technology
Higher mathematics is one of basic subject in colleges and universities, and many subjects be unable to do without higher mathematics, therefore learn high number well
Learn very necessary.But have many concepts very abstract in higher mathematics, therefore student is difficult to understand for, especially in higher mathematics
Curvature portion.Students are allowed more intuitively to understand that curved surface is teachers' very concern.
Embodied the problem of can often make abstract by teaching aid during teaching.Existing curved surface demonstration teaching aid is big
All there is the problem of function is single, existing teaching aid can only demonstrate a kind of curved surface, it is impossible to realize that teaching aid is drilled multifunctional curved comprehensively
Show, be unfavorable for the understanding of students.Therefore, a kind of curved surface demonstration teaching aid of multi-functional automation is developed very necessary.
Utility model content
There is problem in the utility model, propose a kind of higher mathematics special-purpose multifunctional curved surface demonstration teaching aid for more than.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of higher mathematics special-purpose multifunctional is bent
Face demonstration teaching aid, is broadly divided into housing, fore shell control panel and driving exhibiting device three part composition,
The housing includes rear shell and fore shell, and it is aluminum alloy material, and intensity is high and lightweight；
The fore shell control panel includes liquid crystal display, and direction of rotation controller and device start stop control group
Into；The control panel it is integrated with fore shell in；The liquid crystal display is located on the left of fore shell；The direction of rotation controller and dress
Startup stop control is put up and down and column distribution, on the right side of liquid crystal display；
The driving exhibiting device is by central shaft, connection outer bar, connection interior bar, fixator, fixing nut and curved surface bar structure
Into.The central shaft is driving core axis body, by housing drive motor；It is described connection outer bar be embedded in central shaft top and under
Portion；The connection interior bar is embedded in connection outer bar, and connection interior bar is freely stretched in connection outer bar, with adjustment length；The fixation
Device is placed in boom end in connection, and curved surface bar is fixed on into fixator end by fixing nut.
The utility model beneficial effect：
1. automaticity is high, one, which builds startup, stops control；
2. diversified forms teaching curved surface can be shown；
3. equipment is light, it is easy to carry.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the utility model local structural graph.
Embodiment
The utility model is described in further detail below in conjunction with Fig. 1 and 2.
A kind of higher mathematics special-purpose multifunctional curved surface demonstration teaching aid, is broadly divided into housing, fore shell control panel and driving exhibition
The part of showing device three is constituted,
The housing includes rear shell 1-1 and fore shell 1-2, and it is aluminum alloy material, and intensity is high and lightweight；
The fore shell control panel includes liquid crystal display 2-1, and direction of rotation controller 2-2 and device, which start, stops control
Device 2-3 is constituted；The control panel it is integrated with fore shell 1-2 in；The liquid crystal display 2-1 is located on the left of fore shell 1-2；It is described
Direction of rotation controller 2-2 and device start stop control 2-3 up and down and column distribution, on the right side of liquid crystal display 2-1；
The driving exhibiting device is by central shaft 3-1, connection outer bar 3-2, connection interior bar 3-7, fixator 3-3, fixed spiral shell
Female 3-5 and curved surface bar 3-4 is constituted；The central shaft 3-1 is driving core axis body, by the drive motor of housing 1；The connection
Outer bar 3-2 is embedded in central shaft 3-1 tops and bottom；The connection interior bar 3-7 is embedded in connection outer bar 3-2, and connection interior bar 3-7 is even
Connect in outer bar 3-2 and freely stretch, with adjustment length, the fixator 3-3 is placed in connection interior bar 3-7 ends, by fixing nut 3-5
Curved surface bar 3-4 is fixed on fixator 3-3 ends.
Operation principle：
During utility model works, enclosure interior motor, which is rotated, drives central shaft 3-1 to rotate, meanwhile, central shaft 3-1 drives
Connection outer bar 3-2 is rotated with being connected interior bar 3-7, and the fixator 3-3 positioned at connection interior bar 3-7 ends will be used for curved surface displaying curved surface
After bar 3-4 is fixed, rotated with central shaft 3-1, face is formed of a wire in rotation process.Wherein, the utility model is equipped with a variety of
Shape curved surface bar 3-4 is used for the displaying for realizing a variety of curved surfaces.
The above describes embodiment of the present utility model, those skilled in the art by reference to Fig. 1 and Fig. 2
It will be appreciated that product of the present utility model is not only only limited to embodiment described above, without departing from spirit of the present utility model
In the case of various modifications may be made, it is described modification also should be included in the utility model within the scope of.It is of the present utility model
Scope should be limited by appended claims and its equivalent.
