Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-10, a chinese language and literature vocabulary division show shelf, comprising a base plate 1, 1 top fixedly connected with riser 2 of bottom plate, 2 top fixedly connected with roofs 3 of riser, 2 lateral wall fixedly connected with cleaning plates 15 of riser, 1 bottom of bottom plate is equipped with first sliding tray 4, 3 bottoms of roof are equipped with second sliding tray 16, first sliding tray 4 is connected with show board 5 through slide mechanism, show board 5 is polymer alloy granule and epoxy through once only suppressing flexible composite sheet, consequently show board 5 has the smoothness of writing, the clear permanence of writing is not skidded, it is not glistened, do not have the residue after wiping, visual effect splendid effect, the flat panel face is level and smooth, the cambered plate face is the curved surface, have the effect of preventing the reflection of light, enable the student who sits in each corner also can see clearly the writing of board.
Slide mechanism includes a plurality of annular ball grooves 12 of establishing in show board 5 bottom, and ball groove 12 inside wall rotates and is connected with ball 13, ball 13 lateral wall and the 4 lateral walls sliding connection of first sliding tray, and ball 13 diameter is greater than the notch diameter in ball groove 12, therefore ball 13 is difficult for breaking away from ball groove 12, and 4 notches of first sliding tray are lighter to be guaranteed can make things convenient for ball 13 rolling while can not collect up the dust simultaneously.
5 tops of show board are passed through coupling mechanism and are connected with roof 3, coupling mechanism includes the rotation axis 17 of fixed connection at 5 tops of show board, rotation axis 17 lateral wall rotates and has cup jointed plectane 18, 18 lateral walls of plectane are equipped with circular slot 19, 19 inside wall sliding connection of circular slot has a plurality of rolling pearls 20, 20 diameters of rolling pearls are greater than 19 notches of circular slot, 20 lateral walls of rolling pearls and 16 lateral wall sliding connection of second sliding slot, 17 diameters of rotation axis and 16 notches phase-matches of second sliding slot, 18 diameters of plectane are greater than the sliding notch width.
The working principle is as follows: after the mr writes on show board 5 surface, when needing to change new show board 5, only need the pulling to insert and establish board 9, insert and establish board 9 rebound and driving installation piece 8 rebound, installation piece 8 rebound can drive meshing board 24 rebound, thereby extrude gas pushing plate 23, make gas pushing plate 23 rebound, make the air in the cavity 10 outwards blow from gas blowing hole 11, the gas that blows out blows to the dust removal groove, the chalk dust in the dust removal groove blows out.
Meanwhile, as the inserting plate 9 moves upwards, the inserting plate 9 is separated from the collecting groove 14, and the inserting plate 9 is pulled, so that the display plate 5 rotates around the supporting plate 22, the wiped display plate 5 rotates to the front, and meanwhile, the display surface with the written characters rotates to the back.
Wherein the board 9 of inserting of left and right sides is reversed the change each other, when the show board 5 at the back passes through cleaning plate 15, cleaning plate 15 cleans the characters on the show board 5, the powder of wiping chalk seal of a government organization in old china produces drops to collection groove 14 owing to having the stopping of riser 2, left board 9 of inserting inserts under the expanding spring 21 effect and collects in the groove 14 simultaneously, along with show board 5 rotates together, from a left side right with the chalk powder in the collecting groove 14 promote to the dust removal groove in, when the board 9 of inserting of front pulling moves the leftmost end, another board 9 of inserting also is located collecting groove 14 tip, show board 5 has been restricted to rotate by the effect of collecting groove 14, loosen board 9 of inserting, left board 9 of inserting inserts to collecting groove 14.
The display board 5 is changed and then written again, and only repeated operation is needed when the writing surface needs to be changed.
