Description
Technical field：
The utility model is related to a kind of expansible multi-media whiteboard of the plate face used in teaching.
Background technology：
, it is necessary to show lively model dynamic menu by multi-media whiteboard in the physics teaching of university.These
If the broadcasting ratio of picture selects the wide ratio display screen best results of prolate, the viewing feature of human eye is also best suitable for.However,
Traditional multi-media whiteboard is all slightly longer than high, close to square curtain plate, and the rectangle of prolate curtain plate floor space
Greatly, inconvenience storage and transport.
Utility model content：
The purpose of this utility model is to provide a kind of expansible multi-media whiteboard of the plate face used in teaching.
Above-mentioned purpose is realized by following technical scheme：
A kind of expansible multi-media whiteboard of plate face used in teaching, its composition includes：The electronic whiteboard of square
Mainboard, described electronic whiteboard mainboard is rack-mount, and multimedia projector, described electronics are provided with described support
Blank mainboard surface is covered with the expansion board for being similarly square, and described expansion board includes four square platelets, and two just
Square platelet is one group；
Described square platelet includes two set squares, and the set square described in two passes through gemel connection at right-angle side
Together, the apex of the apex of one of set square and described electronic whiteboard mainboard is by spacing ball chain connection,
The apex of another set square and the set square apex sphere chain connection with the square platelet of group；Described spacing spherical hinge limit
Set square processed, can with plane where electronic whiteboard mainboard while limiting set square around the axis rotation perpendicular to electronic whiteboard mainboard
10 degree are no more than with the inclination angle of formation；
Described support has two extension poles, and the end points of described extension pole has magnet, after expansion board expansion,
The magnet of described extension pole is fixedly connected with the pin joint absorption of set square.
The expansible multi-media whiteboard of plate face used in described teaching, described pedestal lower end is provided with universal
Wheel.
The beneficial effects of the utility model：
The utility model provides a kind of brand-new electronic whiteboard mode of extension, ingenious just with spherical hinge and hinge
The geometrical feature of plate has been used, without slideway, the same expansion for laterally expanding plate of similar slideway has been achieved that.Not deployed electricity
Sub- blank is square, and progress storage transport in the chests such as luggage case can be placed on folding shrinking by adding whiteboard bracket.Exhibition
Electronic whiteboard depth-width ratio after opening is especially suitable for the display of widescreen picture, and multiple continuous transverse directions can be shown in physics teaching
Picture, significantly facilitates the observation habit of people（Usual pitching viewing is easiest to produce fatigue）.Wide high energy of the present utility model
Reach 2, it might even be possible to electronic whiteboard mainboard is adjusted for rectangular slab, so as to increase the ratio of width to height to more than 2.
Spreading principle of the present utility model is as described below：During expansion, square platelet group is with identical principle each to side
To expansion, now illustrated by taking the square platelet group in right side as an example.Above and below two square platelets of right side square platelet group
Arrangement, a respective summit and the summit of electronic whiteboard mainboard pass through spacing ball chain connection.Square platelet is by two piece three
Gusset is constituted, and is connected two set squares using hinge at diagonal, is realized that set square can be rotated around diagonal（Obviously not
Set square can be allowed to hit the rotation of electronic whiteboard mainboard）.Connected between upper and lower square platelet in apex by spherical hinge,
There is spherical hinge connection so as to ultimately form catercorner two summits of square platelet, only one is to want spacing company
Connect so that square platelet is only capable of forming small angle of inclination with electronic whiteboard mainboard.When needing, expansion right side square is small
During plate group, at hand-held spherical hinge, spherical hinge is pulled to perpendicular to the direction of electronic whiteboard mainboard plate face（Obviously can not to perpendicular to
The direction of electronic whiteboard mainboard plate face promotes spherical hinge to hit electronic whiteboard mainboard）, the set square of square platelet is started, logical
Cross hinge drives another set square to be started slightly again, and at this moment hand-held spherical hinge is pulled along horizontal linear to the right, set square
It can just be rotated around spacing spherical hinge, the rotation will not be hindered by other set squares, and hand-held spherical hinge is straight along level to the right
Line is pulled until the square platelet group in right side is thoroughly unfolded, and the rectangle plate face that formation is expanded, spherical hinge is extended pole
Magnet adsorption is fixed.The technical scheme of the application is ingenious to make use of spacing spherical hinge and hinge, during square platelet rotation just not
It strictly can planar rotate, but three-dimensionally rotate.Extension pole is hinged on support, when two groups of squares of expansion board
After platelet expansion in place, at rotation extension pole to set square apex sphere hinge position, spherical hinge is adsorbed by magnet, so that
Expansion board is fixed, so as to form the electronic whiteboard that width is doubled.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is rearview of the present utility model.
Accompanying drawing 3 is structural representation when the utility model electronic whiteboard mainboard is not deployed.
