Abstract
The utility model discloses a bookrack for mathematical education. The bookrack for mathematical education comprises a base and two supports inserted in the base. A supporting board body is movably connected between the two supports. The supporting board body can be detached to be used as a drawing board. An upper supporting board extending forwards is arranged on the upper portion of the supporting board body. A lower supporting board extending forwards is arranged on the lower portion of the supporting board body. A magnifying lens is clamped between the upper supporting board and the lower supporting board so that when a teacher is far away from the bookrack or a teacher with weak vision uses the bookrack, the magnifying lens can be clamped in a clamping groove, characters on a textbook can be magnified, and the teacher can use the bookrack conveniently. A scale is arranged on the supporting board body so that measurement or drawing can be facilitated. A circular gap is formed in the supporting board body so that chalk can be placed in the circular gap and a circle can be drawn along the track of the circular gap. The supports comprise the long support and the short support so that the height of each support can be adjusted and the bookrack can be used by teachers with different heights conveniently. The bookrack for mathematical education is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of bookshelf for mathematics teaching.
Background technology
Math teacher need to be drawn auxiliary view at blackboard in teaching process, yet the picture auxiliary view generally all is a hand-held drawing board takes chalk on the other hand, this moment, teacher's textbook or teaching materials just can only be placed on the desktop, textbook keeps flat the inconvenient teacher of desktop and uses, therefore need bookshelf that textbook is supported, although existing bookshelf angle is adjustable, but teacher from bookshelf away from the time or the weak teacher of eyesight when using, writing on the textbook will blur and not see, use very inconvenient, and existing bookshelf can only use function singleness as bookshelf.
The utility model content
The technical problems to be solved in the utility model is for defects, and a kind of textbook writing, multi-functional bookshelf for mathematics teaching of amplifying is provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of bookshelf for mathematics teaching with following structure, comprise base and the two stands that is inserted on the base, be connected with poppet body between the described two stands, its design feature is that the top of described poppet body is provided with the mounting plate that protracts, the bottom of supporting plate is provided with the bottom plate that protracts, and is connected with magnifying glass between described mounting plate and the bottom plate.
The lower surface of described mounting plate is provided with upper groove, and the upper surface of bottom plate is provided with the low groove corresponding with upper groove.
Described poppet body is provided with scale, but subsidiary or mapping.
Described poppet body is provided with circular void, and the width of described circular void is greater than the maximum gauge of chalk.
Described support comprises long stent and short support, and described short support is provided with the through hole that can supply bolt to pass, and described long stent is provided with a plurality of installing holes corresponding with through hole.
Described base is provided with storage trough.
Adopt the bookshelf for mathematics teaching of such scheme compared with prior art to have the following advantages: poppet body is movably connected between the two stands, therefore poppet body is detachable, drawing board uses separately, be connected with magnifying glass in the draw-in groove between poppet body mounting plate and the bottom plate, when teacher is far away apart from bookshelf or the weak teacher of eyesight when using bookshelf, magnifying glass can be snapped fit onto in the draw-in groove, amplify the writing on the textbook, make things convenient for teacher to use; But the scale subsidiary or the mapping that arrange on the poppet body; Poppet body is provided with circular void, chalk can be placed in the circular void and draw circle along its track; Support comprises long stent and short support two parts, so that the height of support is adjustable, the teacher of convenient different heights uses; Can place the educational aids such as chalk in the storage trough on the base, and the utility model is simple in structure, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment
As depicted in figs. 1 and 2, this bookshelf for mathematics teaching comprises base 1 and the two stands 9 that is inserted on the base 1, be connected with poppet body 2 between the described two stands 9, the inboard of two stands 9 is respectively equipped with jack, two outsides of poppet body 2 are respectively equipped with two the square inserted blocks corresponding with jack, two inserted blocks are inserted in two jacks, realize being flexibly connected between poppet body 2 and the two stands 9.Poppet body 2 in the utility model can have sweptback angle, makes things convenient for teacher to use.The top of poppet body 2 is provided with the mounting plate 3 that protracts, the bottom of supporting plate 2 is provided with the bottom plate 4 that protracts, the lower surface of described mounting plate 3 is provided with upper groove 6, the upper surface of bottom plate 4 is provided with the low groove 7 corresponding with upper groove 6, be connected with magnifying glass 5 between described mounting plate 3 and the bottom plate 4, can amplify the writing of textbook on the poppet body 2 so that the teacher uses.Distance between the mounting plate 3 that protracts and bottom plate 4 and the poppet body 2 can stretch into for hand, makes things convenient for the textbook page turning.Poppet body 1 is provided with scale 10, but subsidiary or mapping.Poppet body 2 is provided with circular void 8; the width of circular void 8 is greater than the maximum gauge of chalk; can be placed in the circular void 8 and along the track of circular void 8 for chalk and draw circle; owing to being flexibly connected between poppet body 2 and the two stands 9; therefore poppet body 2 can disassemble, and measures, draws separately the uses such as circle when drawing board.Support 9 comprises long stent 11 and short support 12, described short support 12 is provided with the through hole 13 that can supply bolt to pass, long stent 11 is provided with installing hole 14 corresponding to a plurality of and through hole 13, bolt is passed through hole 13 and installing hole 14, by locking nut long stent 11 and short support 12 are fixed as one, make support 9 highly adjustable.Also be provided with storage trough 15 on the base 1, the educational aids such as chalk can be placed in the storage trough 15.
During use textbook is placed on the poppet body 2, the bottom plate 4 of poppet body 2 is held the textbook bottom, magnifying glass 5 can be snapped fit onto in upper groove 6 and the low groove 7 according to demand, regulate according to demand again the correspondence position of installing hole 14 and through hole 13, realize that support 9 is highly adjustable.Because between support 9 and the base 1, be the plug-in mounting relation between poppet body 2 and the two stands 9, so the utility model integral body is dismountable, makes things convenient for mobile and carries.
