Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
(coiling stake and elasticity bundling belt in Fig. 2, is eliminated as Suo Shi Fig. 1 ~ 8, Fig. 6 eliminates elasticity bundling belt, ), a kind of Folding blackboard of the present utility model, comprise blackboard main body 1 and two supporting legs 2, blackboard main body comprises the frame 3 being arranged on plate face surrounding, wherein, blackboard main body is divided into the separate substrates 101 that four block sizes are equal in their length direction, linked together by the first hinge 102 between adjacent separate substrates, four separate substrates are mutually superimposed after can fold as shown in Figures 2 and 3 equally, and blackboard front protecting is got up, blackboard front can not be worn and extrude, the two pieces of separate substrates back sides being positioned at both sides in four pieces of separate substrates are all fixed with a circular sleeve 4 set up and down, supporting leg is " Shang " shape supporting leg connected to form by a cross bar 201 and a montant 202, the cross section of montant is circular, montant can be pipe and also can be round bar, montant slides up and down to be socketed in described circular sleeve, when montant upward sliding, rotating horizontal pole makes it parallel with blackboard panel, therefore cross bar can be moved upward to the blackboard back side, and then make whole supporting leg be hidden in the blackboard back side, the upper portion side wall of circular sleeve and lower sides are provided with tapped through hole, and two equal adaptations of tapped through hole have set bolt 5, the upper portion side wall of montant offers two set bolts of two screwed holes, 6, two screwed holes respectively described in correspondence, and two screwed holes to offer direction orthogonal, one of them screwed hole offer the plane of direction perpendicular to described cross bar and montant composition.
Cross bar is divided into two independent cross bars 2011 by itself and montant junction, two independent cross bars are connected to montant lower end respectively by two the second hinges 2012, second hinge is can meet described independent cross bar to be rotated down to 90 ° of hinges with montant parallel position, and namely hinge makes independent cross bar can keeping rotating in the scope of 90 ° and 180 ° with montant.
When four separate substrates strut completely, the latch 7 by arranging on frame between two adjacent separate substrates links together, and between adjacent two separate substrates, one is provided with bolt rod, and another is provided with slotting nose, connects to realize latch.
The substrate back being fixedly installed circular sleeve is disposed with four coiling stakes 8 from top to bottom, and topmost is all fixedly connected with hook 10 with the other end coiling stake of foot being all fixedly connected with an elasticity bundling belt 9, two elasticity bundling belts.
Two independent cross bars 2011 are expansion link, independent cross bar forms by interior bar 2013 with the outer tube 2014 that interior bar is slidably matched, one end of interior bar and montant are hinged, outer tube is provided with fastening bolt 2015, after outer tube pull-out certain distance, interior bar and outer tube are fixed up by available fastening bolt.The substrate back being fixedly installed circular sleeve is fixedly installed cross bar container cavity 11 below circular sleeve, this cross bar container cavity upper end is communicated with circular sleeve, lower ending opening, cross bar container cavity and the cross bar after folding are slidably matched, and namely slidably coordinate after cross bar is folding and push cross bar container cavity.
When the utility model is deposited, as Fig. 3, blackboard is folded into four pieces of separate substrates mutually superposed, the montant of supporting leg and cross bar are enclosed in circular sleeve and cross bar container cavity, now the tapped through hole on top aligns with a screwed hole on montant top, and the set bolt on top is screwed in this screwed hole, thus is fixed on by whole supporting leg in circular sleeve and cross bar container cavity, and then tie four pieces of separate substrates mutually superposed with elasticity bundling belt, as described in Figure hook extension is got back in coiling stake, when the utility model uses, as Fig. 6 and 7, elasticity bundling belt is untied, and two elasticity bundling belts are wrapped in coiling stake to prevent elasticity bundling belt at random, then four separate substrates are launched, fix to prevent adjacent separate substrates from rotating with latch, the set bolt on two circular sleeve tops is screwed out screwed hole, again supporting leg is extracted out downwards and two independent cross bars under opening montant, rotating montant makes two independent cross bars perpendicular to blackboard panel, another screwed hole that supporting leg continues the tapped through hole and montant top being drawn to bottom downwards aligns, the set bolt of bottom is screwed in this screwed hole with fixed supporting leg.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
