Description

Two-face combined blackboard with box

A kind of pin-connected panel Dual-side blackboard with placing box belongs to the school supply and stationery technical field, is mainly used in teaching and propaganda.

In prior art commonly used having be fixed on the teaching on teaching or the propaganda place wall or the usefulness of running a newspaper blackboard, be used for office's account or write the movably suspension type blackboard of notice, and the practise handwriting small blackboard etc. of usefulness of rural elementary school life.These blackboards are monoblock entirely, except that the pupil practise handwriting usefulness, mostly be single face, need have two people to lift at least during indivedual two-sided change-over panel face and turn-take and could realize; Fixed plate face is big, and information capacity is big, but heavy, can not move and can not make full use of; Usefulness has to carry and deposits convenient advantage though the pupil practises handwriting, and the palette face is too little, and practicality is little; Though movably the suspension type blackboard is more flexible, certain information capacity is arranged, if be used for teaching and propaganda, that its plate face seems again comparatively speaking is not enough and mobile, it is also not too convenient to deposit.

The purpose of this utility model be to provide a kind of portable and smart, removable, information capacity is big, writing on the blackboard is convenient, can keep flat to hang, the time spent assembly unit, the time spent is not taken the pin-connected panel Dual-side blackboard of the band placing box deposited of vanning apart.

According to teaching and propaganda work to the actual requirement of blackboard, subject matter at the prior art existence, basic design of the present utility model is: a big blackboard panel is divided into the some two-sided rectangular slab faces that all can write, on a gossamery support plate, install to turn and above-mentioned small piece plate face can be connected the frid formula framework that is assembled into the bulk blackboard with folding, be equipped with a chest that adapts with above-mentioned plurality of small blocks plate face again, be assembled into the bulk blackboard again after the time spent piecemeal writing on the blackboard, the time spent is not converted into fritter and puts into case.

The pin-connected panel Dual-side blackboard that is characterised in that described band placing box of the present utility model, the metal matter bound edge of the band arc chord angle of being inlayed by the identical two-sided rectangle assembly unit plate faces that all can write of at least three thickness size, every rectangular slab face periphery, at least six plate face assembly units connect the framework frid of usefulness, above-mentioned frid assembling support plate, at least four limiting plates, at least four connect connecting axle and placing box that above-mentioned frid and limiting plate use and constitute.The framework frid meta that above-mentioned six plate face assembly units connect usefulness is parked in when three assembly units of above-mentioned support plate bottom and is the single face frid on the horizontal level, promptly groove is arranged above only, remaining is two-sided frid, promptly up and down or about face groove is all arranged, be positioned at above-mentioned support plate up and down a single face frid (following) at horizontal sides middle part and the front that a two-sided frid (top) directly is fixedly mounted on support plate, all the other four are being installed on above-mentioned frid assembling support plate with four above-mentioned limiting plates respectively by four above-mentioned connecting axles and are just locating for four jiaos, (frid is in the front on the back of the body two sides, limiting plate overleaf), the frid that is horizontal during assembly unit is vertical mutually with the corresponding limiting plate in the support plate back side, and the axis hole on the support plate that passes of their connecting axle inside; Axis hole on the support plate that the corresponding limiting plate of the frid that is in vertical position during assembly unit and the support plate back side is parallel to each other and their connecting axle passes outside, so that not the time spent can both turn back support plate surrounding place, fixedly connected with limiting plate with above-mentioned frid respectively in all above-mentioned connecting axle two ends, the axis holes at four jiaos of places of these and support plate then are and are slidingly matched, so that frid and limiting plate all can rotate in the support plate plane around this axle, every limiting plate side has a spacing breach, after frid and limiting plate turn over 90 ° synchronously, this breach is stuck on the limited post that is positioned at the support face back side, to reach spacing purpose.Plate face above-mentioned during assembly unit inserts in the above-mentioned spacing corresponding groove of framework frid, and the time spent does not take each plate face apart and puts into above-mentioned placing box.Above-mentioned placing box is by a backplate, an active clapboard, a band is got the front panel in book hole, two soft sidewalls of fold formula (each only is equivalent to a half-breadth of flank wall after drawing back), four bolts, two blocks, the drawer of two (each one at each sidewall forward lower comer place) spacing breach of base band, four springs and two semi-enclosed casings of rectangle that limited post constitutes, above-mentioned backplate and front panel are fixedly connected into cabinet shell by above-mentioned bolt at the Si Jiaochu of plate, above-mentioned active clapboard and bolt are and are slidingly matched, the above-mentioned soft sidewall of fold formula is fixedlyed connected with above-mentioned front panel and active clapboard, above-mentioned spring housing is on the screw rod of each bolt at place, four angles, their end is fixed on the angle of front panel correspondence, the other end is fixed on the corresponding angles of above-mentioned active clapboard, this active clapboard is divided into the whole box body inner chamber the back chamber and the cup of putting book of the above-mentioned blackboard surface of placement of variable size, cup has the soft sidewall of fold formula, back chamber does not have sidewall paneling and does not also have base plate, whole box body does not all have loam cake, and the top of above-mentioned backplate and active clapboard central authorities and dual-side central authorities respectively establish a breach that picks and places blackboard surface.

The utility model has the advantages that: because the dismantled and assembled not time spent is put into case, so this blackboard is easy to carry, dismounting is simple to operate, can lie in the well later assembly unit again of writing on the blackboard on the desktop, and the big I of plate face is adjusted the writing on the blackboard convenience according to actual needs, the plate face is rationally distributed, can make full use of the plate face, tow sides can be used, and information capacity is big, can be when preparing lessons writing on the blackboard good, save time in classroom, improve teaching efficiency, writing on the blackboard once can be used repeatedly and can maintain secrecy for the comparison convention.Be provided with case chamber of putting book and the drawer of putting chalk and blackboard eraser, the many usefulness of a tool are made easily, and raw material are easy to get, and cost is low, and purposes is wide.
