Description
Technical field
The utility model belongs to teaching technique with the apparatus field, is specifically related to a kind of mathematical education curved surface demonstrating model.
Background technology
Give lessons in practice long-term, teaching is demonstrating in surface model process for student, common surface model can only demonstrate outer arc surface or interior arc surface, teacher needs to prepare multiple surface model before giving lessons, and can waste hours of instruction when changing multiple surface model, inconvenient teacher uses and increases careful preparation work.
Summary of the invention
The purpose of this utility model is: demonstrating in surface model process for student in order to solve to teach, teacher can demonstrate outer arc surface and inner arc surface model at any time, and teacher can be reduced in preliminary work before the class, teacher can be saved and change model time, facilitate teacher to use and save hours of instruction, its technical scheme is as follows:
A kind of mathematical education curved surface demonstrating model, it comprises fixed underpan 1, curved slab 2, puller strap 3, fixedly take over a business 4, vertical columns 5, fixing snap ring 6, tension rope 7, jam 8, it is characterized in that: on described firm banking 1, top end surface edge is evenly distributed and is fixedly connected with several curved slabs 2, puller strap 3 is fixedly connected with between each corresponding described curved slab 2, on described curved slab 2, top end surface is fixedly connected with and fixedly takes over a business 4, on described firm banking 1, top end surface circle centre position is fixedly connected with vertical columns 5, and top penetrates and describedly fixedly takes over a business 4 on described vertical columns 5, top end surface top edges place, described vertical columns 5 side is fixedly connected with fixing snap ring 6, on described vertical columns 5, top end surface circle centre position is fitted with tension rope 7, on described tension rope 7, top end surface is fixedly connected with jam 8, on described vertical columns 5, top end surface circle centre position is hollow shape, and puller strap 3 is inserted into described vertical columns 5 inside described in every root, and puller strap 3 is fixedly connected with described tension rope 7 described in every root, describedly fixedly take over a business top end surface circle centre position on 4 and be provided with through hole, and described vertical columns 5 is inserted into described through hole inside, described through hole inside diameter is identical with described vertical columns 5 overall diameter, described vertical columns 5 side top end surface is provided with several spring stacks.
The beneficial effects of the utility model are: demonstrating in surface model process for student in order to solve to teach, teacher can demonstrate outer arc surface and inner arc surface model at any time, and teacher can be reduced in preliminary work before the class, teacher can be saved and change model time, facilitate teacher to use and save hours of instruction.
accompanying drawing illustrates:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
embodiment:
With reference to a kind of mathematical education curved surface demonstrating model described in Fig. 1, it comprises fixed underpan 1, curved slab 2, puller strap 3, fixedly take over a business 4, vertical columns 5, fixing snap ring 6, tension rope 7, jam 8, it is characterized in that: on described firm banking 1, top end surface edge is evenly distributed and is fixedly connected with several curved slabs 2, puller strap 3 is fixedly connected with between each corresponding described curved slab 2, on described curved slab 2, top end surface is fixedly connected with and fixedly takes over a business 4, on described firm banking 1, top end surface circle centre position is fixedly connected with vertical columns 5, and top penetrates and describedly fixedly takes over a business 4 on described vertical columns 5, top end surface top edges place, described vertical columns 5 side is fixedly connected with fixing snap ring 6, on described vertical columns 5, top end surface circle centre position is fitted with tension rope 7, on described tension rope 7, top end surface is fixedly connected with jam 8, on described vertical columns 5, top end surface circle centre position is hollow shape, and puller strap 3 is inserted into described vertical columns 5 inside described in every root, and puller strap 3 is fixedly connected with described tension rope 7 described in every root, describedly fixedly take over a business top end surface circle centre position on 4 and be provided with through hole, and described vertical columns 5 is inserted into described through hole inside, described through hole inside diameter is identical with described vertical columns 5 overall diameter, described vertical columns 5 side top end surface is provided with several spring stacks.
When demonstrating positive camber, first fixedly take over a business 4 by fixedly taking over a business 4 simultaneously slide to pressing down at vertical columns 5, curved slab 2 is bent outwardly and pulls puller strap 3 and tension rope 7 simultaneously, finally using spring stack to block fixedly taking over a business 4, pressing through the hole place that large jam 8 may be stuck in top on vertical columns 5 as follows.
When demonstrating negative camber, first pull tension rope 7 to drop puller strap 3, curved slab 2 is curved inwardly, fixedly take over a business 4 simultaneously and slide to fixed underpan 1, finally same spring stack blocks fixedly taking over a business 4.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
