The demonstration board is applied to the education field.
Description
Technical field
the utility model relates to a kind of pedagogy demonstration board.
Background technology
now in upper pedagogy class hour needed key content and emphasis knowledge, all need to be at the enterprising andante book of blackboard, a large amount of writings on the blackboard are lost time very much, also incur loss through delay the teaching time simultaneously, affect teaching progress.
Summary of the invention
the purpose of this utility model is to provide a kind of a kind of pedagogy demonstration board that can reuse, reduce the writing on the blackboard time.
above-mentioned object realizes by following technical scheme:
a kind of pedagogy demonstration board, its composition comprises: middle link plate, the back side of described middle link plate is connected and fixed bar, the left side of described fixed strip, right side, middle part all has inserting groove, the described inserting groove on left side and right side is connected and fixed supporting leg, the bottom of the described inserting groove of middle part has positioning port, the top of the described inserting groove of middle part connects left slideway and right slideway, described left slideway connects left axle sleeve, described left slideway connects right axle sleeve, the rotating shaft of all pegging graft of described left axle sleeve and described right axle sleeve, described rotating shaft connects telescopic outrigger, described telescopic outrigger is through the described inserting groove of middle part.
described a kind of pedagogy demonstration board, described left slideway, described right slideway, described left axle sleeve, described right axle sleeve are ferrous material, between described left slideway and described left axle sleeve, locate by magnetic patch, between described right slideway and described right axle sleeve, locate the magnetic patch described in the afterbody adhesive of described left slideway and described right slideway by magnetic patch.
described a kind of pedagogy demonstration board, the equal connection hinge in the left side of described middle link plate and right side, described hinge connects respectively left folding lamination and right folding lamination, described left folding lamination, described right folding lamination, described middle link plate all connect grafting frame, the top of described grafting frame has interface, described interface grafting pedagogy courseware card.
described a kind of pedagogy demonstration board, the fixed supporting leg described in 2 and the distribution triangular in shape of described telescopic outrigger, the equal connecting sucker in bottom of described fixed supporting leg and described telescopic outrigger.
beneficial effect:
1. when telescopic outrigger and the fixed supporting leg support of middle the link plate that the utility model adopts, distribution triangular in shape, the stablizing of support, result of use is good.
telescopic outrigger of the present utility model, in the time not using, does not take up room on link plate in the middle of being attached to, and deposits and carry all to facilitate.
in the middle of of the present utility model, link plate, left folding lamination and right folding plate development formula become a plane, and the different courseware of can pegging graft is convenient to teaching, and courseware is pegged graft convenient, changes easily.
when in the middle of of the present utility model, link plate, left folding lamination and right folding lamination do not use, left folding lamination and right folding lamination are folded on middle link plate, easy to carry.
