Abstract
The utility model provides a bookshelf for mathematical teaching, which belongs to the field of the auxiliary teaching tool. The structure of the bookshelf comprises suckers and a supporting plate, and also comprises a sucker support, wherein the suckers are respectively arranged on the upper end and the lower end of the back part of the sucker support, the upper end and the lower end of the front side of the sucker support are respectively provided with a retractable rod which is connected with the bottom end of the sucker support, and the top ends of the retractable rods are respectively hinged with the back part of the supporting plate. Compared with the prior art, the bookshelf has characteristics of reasonability in design, simpleness in structure, convenience in use, capability of alleviating the labor intensity of the teacher and improving the teaching efficiency, and the like.
Description
Technical field
The utility model relates to a kind of teaching appurtenance, and specifically a kind of mathematical education is with putting bookshelf.
Background technology
In the mathematical education classroom, need teacher on the blackboard of being everlasting, to write formula and drawing etc., when writing again through drawing instrument if desired, just need be placed on teaching notes on the lectern, painting turns round after the something again checks the content on the teaching notes; Even if when not needing drawing instrument to write, also want hand-held teaching notes, the another hand is write with chalk, thus, lets teacher feel like hell, and efficiency of teaching is low, brings very big inconvenience to teaching.
Summary of the invention
The technical assignment of the utility model is the deficiency to prior art, provides a kind of reasonable in design, mathematical education that result of use is good with putting bookshelf.
The utility model solves the technical scheme that its technical problem adopted: comprise sucker and supporting plate; Also comprise sucker stand; Said sucker is separately positioned on the two ends up and down at sucker stand back; The positive two ends up and down of sucker stand are respectively arranged with expansion link and are connected with its bottom, and the expansion link top is hinged with said supporting plate back respectively.
Expansion link is divided into expansion link and following expansion link, and last expansion link bottom is fixedly connected with sucker stand, and following expansion link bottom and sucker stand are hinged.
The supporting plate lower end is provided with book clamp.
A kind of mathematical education of the utility model is with putting bookshelf compared with prior art, and the beneficial effect that is produced is:
Have characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, it is comparatively convenient to operate, and lets teacher have more energy to go to write, and has both reduced teacher's labour intensity, has improved efficiency of teaching again.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: 1, sucker, 2, sucker stand, 3, go up expansion link, 4, supporting plate, 5, book clamp, 6, expansion link down.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done following the detailed description.
Shown in accompanying drawing; A kind of mathematical education of the utility model is with putting bookshelf; Its structure comprises sucker 1 and supporting plate 4, also comprises sucker stand 2, and said sucker 1 is separately positioned on the two ends up and down at sucker stand 2 backs; Sucker stand 2 positive two ends up and down are respectively arranged with expansion link and are connected with its bottom, and the expansion link top is hinged with said supporting plate 4 backs respectively.
Expansion link is divided into expansion link 3 and following expansion link 6, and last expansion link 3 bottoms are fixedly connected with sucker stand 2, and following expansion link 6 bottoms and sucker stand 2 are hinged.Supporting plate 4 lower ends are provided with book clamp 5.
Can this bookshelf be adsorbed on the blackboard panel through sucker 1, the position of absorption can be regulated according to the personal considerations voluntarily.Teaching notes are placed on the supporting plate 4, are fixed with book clamp 5, prevent its page turning, the front and back position of supporting plate 4 can be regulated through expansion link, and the angle of supporting plate 4 also can be regulated through following expansion link 6, so that the teacher checks teaching notes.
A kind of mathematical education of the utility model is simple and convenient with putting its processing and fabricating of bookshelf, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be this professional's known technology.
Claims (3)
1. a mathematical education is with putting bookshelf; Comprise sucker and supporting plate; It is characterized in that also comprising sucker stand; Said sucker is separately positioned on the two ends up and down at sucker stand back, and the positive two ends up and down of sucker stand are respectively arranged with expansion link and are connected with its bottom, and the expansion link top is hinged with said supporting plate back respectively.
