Abstract
The utility model relates to a parabolic demonstration teaching aid of college mathematics teaching, including base, support frame, pivot, parabola, be provided with the support frame on the base, the pivot is passed from the support frame, and the pivot is provided with the bearing with the junction of support frame, and the pivot is rotated with the support frame and is connected, is provided with parabola in the pivot, parabola summit and pivot one end head are connected, and the pivot other end is the crank type structure of connecting rod and handle constitution, through turning handle, drive pivot and parabola to make parabola move in succession, form the parabola in the vision, this teaching aid simple manufacture, it is with low costs.
Description
Technical field
The utility model relates to teaching aid field, specifically relates to a kind of College Mathematics Teaching parabola demonstration teaching aid.
Background technology
Higher Mathematics Teaching comprises the special surfaces such as parabola, and in reality, paraboloidal application also widely, and parabola, in teaching process, also do not have special teaching aid, and this partial knowledge is very abstract, brings inconvenience therefore to the explanation of this partial knowledge.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of College Mathematics Teaching parabola demonstration teaching aid.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of College Mathematics Teaching parabola demonstration teaching aid, comprise base, bracing frame, rotating shaft, para-curve, described base is provided with bracing frame, described rotating shaft is passed from bracing frame, the junction of rotating shaft and bracing frame is provided with bearing, rotating shaft and bracing frame are rotationally connected, rotating shaft is provided with para-curve, described para-curve summit is connected with rotating shaft one end head, the rotating shaft other end is the crank-type structure of connecting link and handle composition, described connecting link is vertical with rotating shaft to be arranged, connecting link two ends are connection rotating shaft and handle respectively, described handle is vertical with connecting link to be arranged.
Further scheme: described base is provided with fixing parcel tray.
Further scheme: described handle overlaps rubber sleeve, described rubber sleeve is the lines of surface band depression.
The beneficial effect that the utility model compared with prior art has is: by turning handle, drives rotating shaft and para-curve, thus para-curve is moved continuously, visually form parabola.
Accompanying drawing explanation
Fig. 1 is a kind of College Mathematics Teaching parabola of the utility model demonstration teaching aid.
Number in the figure is: 1-base, 2-bracing frame, 3-rotating shaft, 4-para-curve, 5-bearing, 6-connecting link, 7-handle, 8-parcel tray, 9-rubber sleeve.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Known with reference to Fig. 1, a kind of College Mathematics Teaching parabola demonstration teaching aid, comprise base 1, bracing frame 2, rotating shaft 3, para-curve 4, described base 1 is provided with bracing frame 2, described rotating shaft 3 is passed from bracing frame 2, rotating shaft 3 is provided with bearing 5 with the junction of bracing frame 2, rotating shaft 3 realizes being rotationally connected with bracing frame 2 by bearing 5, rotating shaft 3 is provided with para-curve 4, described para-curve 4 summit is connected with rotating shaft 3 one end head, rotating shaft 3 other end is the crank-type structure be made up of connecting link 6 and handle 7, described connecting link 6 one end is vertically connected at rotating shaft 3, the other end is vertically connected at handle 7, by turning handle 7, drive rotating shaft 3 and para-curve 4, thus para-curve 4 is moved continuously, visually form parabola.
Further: described base 1 to be provided with fixing parcel tray 8, the instrument such as chalk, white board marker can be placed.
Further: described handle 7 overlaps rubber sleeve 9, the lines that described rubber sleeve 9 caves in for surface band, skids when preventing from holding handle 7.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
