Abstract
The utility model relates to a kind of mathematics cycloid demonstration teaching aid.Cycloid is that a circle is when rolling along straight line, on circle point of fixity the track of process, in the simulation of traditional mathematical education, teacher by drawing multiple circle with instrument on blackboard, in the rule by looking for the form of a line to embody cycloid, so virtually affect efficiency of giving lessons.A kind of mathematics cycloid demonstration teaching aid, its composition comprises: magnetically support bar (1), magnetic lower support bar (5), between inside described magnetically support bar and magnetic lower support bar, there is disk rolling body (3), on inside described magnetically support bar and magnetic lower support bar, there is semicircle positioning convex (7), described disk rolling body has groove (8), described semicircle positioning convex is stuck in groove, and described magnetically support bar and magnetic lower support bar two ends have baffle plate (4).The utility model is applied to mathematics cycloid demonstration teaching aid.
Description
technical field:
the utility model relates to a kind of mathematics cycloid demonstration teaching aid.
background technology:
cycloid is that a circle is when rolling along straight line, on circle point of fixity the track of process, in the simulation of traditional mathematical education, teacher by drawing multiple circle with instrument on blackboard, in the rule by looking for the form of a line to embody cycloid, so virtually affect efficiency of giving lessons, student understands neither be very thorough, some teachers are by carrying out picture in the process of giving lessons in displaying under class, although solve the situation without the need to picture circle of attending class to a certain extent, but classmate's study is not very directly perceived, can not observe the stroke of cycloid intuitively.Therefore need to design a kind of teaching aid being applied to mathematical pendulum line formation demonstration and carry out auxiliary mathematical education.
summary of the invention:
the purpose of this utility model is to provide a kind of mathematics cycloid demonstration teaching aid.
above-mentioned object is realized by following technical scheme:
a kind of mathematics cycloid demonstration teaching aid, its composition comprises: magnetically support bar, magnetic lower support bar, between inside described magnetically support bar and magnetic lower support bar, there is disk rolling body, on inside described magnetically support bar and magnetic lower support bar, there is semicircle positioning convex, described disk rolling body has groove, described semicircle positioning convex is stuck in groove, and described magnetically support bar and magnetic lower support bar two ends have baffle plate.
described mathematics cycloid demonstration teaching aid, described disk rolling body one side has handle, described disk rolling body another side has one group of chalk standing groove, described chalk standing groove corresponding position has stop means, and described baffle plate is connected with the threaded hole on semicircle positioning convex by screw.
described mathematics cycloid demonstration teaching aid, described stop means comprises postive stop baffle, and described postive stop baffle has gag lever post, described gag lever post overlaps limited location spring.
the beneficial effects of the utility model:
1. the utility model designs a kind of mathematics cycloid demonstration teaching aid, first employing property upper support bar and magnetic lower support bar, can be used for magnetic absorption carries out cycloid demonstration on blackboard, during operation, groove on disk rolling body and the semicircle positioning convex on magnetically support bar and magnetic lower support bar are blocked, then baffle plate is buckled, pass through screw-driving, in the side of disk rolling body, there is chalk standing groove and stop means, load onto chalk, by the handle on rotary disk rolling body, along magnetically support bar and magnetic lower support bar move, blackboard will stay the track of cycloid, simultaneously when use operates, because chalk constantly weares and teares, chalk is constantly ejected the contact that ensure that with blackboard by stop means by spring principle, ensure that cycloid draws smoothly.
the utility model structure is simple, and easy to operate, when teacher gives lessons, classmate can observe the process that cycloid is formed intuitively, more convenient student's rational learning, also substantially increases efficiency of giving lessons simultaneously.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is the utility model magnetically support bar and magnetic lower support bar and disk rolling body schematic diagram.
accompanying drawing 3 is the utility model disk schematic diagram.
