Description

Standard school wall map device
Technical field
The utility model relates to the daily teaching appliance of a kind of middle and primary schools, i.e. standard school wall map device.
Background technology
1. Chinese primary and secondary teaching material is synthetic by textbook content and teaching figure content two parts, and the teaching figure is divided into electronic edition under the multimedia environment and the paper dielectric printing version under traditional classroom again.Investment is big because " central machine room-computer-projecting apparatus-electric projection screen system " is equipped with, security maintenance and operation and maintenance cost is higher, the teacher is individual courseware development and courseware teaching level are difficult to the qualified synchronously reasons such as (directly the basis are the professional application level of relative computer software) of integral body, thereby it is also quite little to realize that at present the hardware system configuration can use the classroom of electronic edition teaching figure to account for the ratio of middle and primary schools of whole society classroom sum.Even (for the classroom of equipping the computer projection system, under the situation that possesses outstanding wall chart device, paper medium school wall map is as the still rational arrangement of the nimble alternative means of graphic rendition.) paper medium school wall map is crucial aided education articles for use, it has content, and precisely intensive, the design specification of the authorization of teaching material level of national primary and secondary teaching material examination board (by), information, suitable large-scale collective read and observation; Especially the acquisition of considering paper medium school wall map is easy, use flexibly, be convenient to characteristics such as multiplexing, for the computer projection system is difficult to surmount and substitute comprehensively; Finance from basic education drops into feasibility again, in a following long term, the common classroom of domestic most of middle and primary schools may will not possess the condition of teaching of use figure electronic edition, promptly still needs fully to use paper medium teaching figure to guarantee the daily teaching standard.
Middle and primary schools classroom slim irony blackboard or cement blackboard or the fiberglass blackboards etc. of adopting more.Using wall chart to carry out classroom instruction is the conventional means that many courses are given lessons, and almost all needs to use wall chart every day in the standard teaching, and paper medium teaching figure to hang up difficulty be generality in middle and primary schools' teaching at present.Because it is inconvenient to hang up, teacher even cancelled the use of teaching figure on considerable classroom has caused China's primary school and middle school teaching quality large tracts of land to descend, and causes the deep internal injury of student at aspects such as cognitive generation type, integrity of knowledges.
At present paper medium teaching figure (hereinafter to be referred as paper figure) in the classroom, comparatively commonly adopt paste stickup, adhesive tape stickup, magnetic patch pressure holding, with drawing pin by hanging up in the first-class method of wall.The dirty hand of sticking hand (as paste, adhesive tape) that these wall chart methods have, have inconvenient unreliable (as drawing pin want that powerful wall, adhesive tape will be cut off by advancing, blackboard has the chalk dust adhesive tape easily to come off), the difficult preservation that has (as the magnet piece in classroom), being taken off by the student easily of having played and damaged (as T-plate), the also damage drawing that has and wall (as the drawing pin mode) or the like.Be example with the magnetic patch adhesive pressure holding paper figure that uses slim irony blackboard, many paper figure drawings big (as high 110cm * wide 90cm and bigger drawing) should hang from above from the blackboard upper edge and descend (blackboard height 1.2-1.0m), but the teacher that stature is not really high (particularly including most of schoolmarm) is difficult to magnetic patch is lifted to the blackboard upper edge, also inconvenience was mobile after paper figure hung up, moreover magnetic patch loses nothing to be surprised in the classroom, and is also very inconvenient as carried by the teacher at every turn; Being example at blackboard panel with adhesive tape adhesive paper figure, paper figure generally fixedly is taking the blackboard stage casing again, can not move conveniently after the paper figure stickup, and promptly blackboard is write with paper figure and is difficult to be used alternatingly easily the blackboard stage casing of favourable students ' reading; And the above various most time spent of method that hangs up paper figure is longer, and the teaching of long period pauses and influence the coherent of Faculty and Students' state of mind, undermines the instruction effect.
For many years, Chinese patent discloses the many designs that are the theme with the wall chart device, they generally can both finish the wall chart task, but all improve inadequately and optimization, what wherein have the more outstanding pattern of dealing with problems is that (Chinese patent CN87200735U can skip movable wall chart device, designer: Ge Jiayu) and Chinese patent 200620046025.6 (portable blackboard hanger, patentee: Shanghai Shangyin Yangpu School, designer: encourage and goodly ooze).Chinese patent CN87200735U has noticed that the conventional method that hangs up paper figure obviously expends time in classroom, save the coherent and good effect easy to use of the time in classroom maintenance state of mind for playing, its structural design is to have an elongated Rod for hanging picture or map can be no more than 180 ° rotation around the frame that is placed in the blackboard upper side frame, the a pair of road wheel of configuration can move horizontally full device along the track that places the blackboard upper side frame on the frame, and this device also has elevating function.Though the design focal point of CN87200735U be utilize its device to stir Rod for hanging picture or map to make it to horizontally rotate 180 ° be replaceable one page paper figure, but still for we provide a kind of valuable wall chart device infrastructure mode.The ZL200620046025.6 purpose is to make things convenient for moving of paper figure (frame) to reach assembly and disassembly conveniently in order to avoid too much block blackboard panel.Specifically: it comprises first track that is fixedly arranged on the blackboard avris, combine with first track and have the sliding part of second track and combine with second track and establish part for the folder that folder is established paper figure.Wherein: first track is wherein one of slide rail and a fluting, and described sliding part is rollered plate body, have the plate body of ball or for having the plate body of draw ring; Second track is one of them person of slide rail and fluting, described folder establish part by embed second track and with externally threaded cylinder and be provided with folder establish the plate body of the clip of described object, in order to described plate body be fixed on described cylinder and have the nut of internal thread and formed at the bayonet lock of described second track so that described cylinder is fixed in order to place the two through hole that is located at described sliding part both sides.In its another embodiment, described folder establish part by embed second track and be provided with folder establish described object clip the bending body of rod and in order to place the two through hole that is located at described sliding part both sides with described bending cylinder is fixed the bayonet lock of described second track institute form.
