Summary of the invention
The purpose of this utility model is a kind of opening and closing left and right Rimless push-and-pull clipboard of design, the both sides Rimless on draw back plate both sides, be interconnected to form profile specification by special left and right integral runners corner support pin, push-and-pull clipboard in left and right can slide by the pulley being fixed on clipboard in upper and lower integral runners; In the time that clipboard is opened, can expose and be positioned at draw back plate middle electronic whiteboard or TV integrated machine, by the folding of clipboard, both can realize the light conversion of electronic instruction and conventional teaching, also can complete the organic unity of conventional teaching and electronic instruction.
The technical solution of the utility model: opening and closing left and right Rimless push-and-pull clipboard of the present utility model comprises left and right pillar, upper and lower integral runners, push-and-pull clipboard, be fixed on the upper lower sheave on push-and-pull clipboard, at left and right pillar, connect upper and lower integral runners by slideway corner support part up and down, push-and-pull clipboard slideway district and the left and right pillar bonding pad before and after integral runners comprises, arranged, the front upper lateral part in push-and-pull clipboard slideway district connects pulley district, the front side of slideway corner support part flushes with top, integral runners push-and-pull clipboard slideway district, push-and-pull clipboard slideway district is sealed, the rear side of slideway corner support part seals the left and right pillar bonding pad of integral runners and has upwards extension to be connected with left and right pillar, push-and-pull clipboard is each one around, at each push-and-pull clipboard, two pulleys is respectively installed up and down, and two pulley arrangements are at inner side and the middle part of push-and-pull clipboard, and upper lower sheave is arranged on the upper and lower side above of push-and-pull clipboard.
Electronic whiteboard or TV integrated machine are installed on the wall of the rear middle part of described integral runners.
There is the spacing end socket of pulley at two ends, integral runners pulley district.
Advantage of the present utility model: the utility model does not resemble traditional draw back plate two clipboards of left and right side frame restriction.The utility model is guaranteed draw back plate structural strength by left and right pillar, and left and right clipboard can slide into outside left and right pillar by pulley in upper and lower integral runners; At two clipboards, all in when locking, frame is concordant with the side frame of draw back plate outside clipboard, can on clipboard, carry out traditional traditional instruction; In the time that clipboard is opened, can expose and be positioned at draw back plate middle electronic whiteboard or TV integrated machine, to carry out audio-visual education programme teaching, and can in carrying out audio-visual education programme teaching, on clipboard, carry out traditional traditional instruction, by the folding of clipboard, can realize the light conversion of electronic instruction and conventional teaching, also can complete the organic unity of conventional teaching and electronic instruction, clipboard has larger writing on the blackboard size simultaneously, can make writing on the blackboard more have continuity, globality.
