| titleOfInvention | A kind of English teaching blackboard and application method |
| abstract | The invention discloses a kind of English teaching blackboard and application methods, including several magnet strips being arranged in blackboard and the sliding rail in blackboard left and right ends is set, slide plate of the setting with idler wheel in the sliding rail, bare electromagnet is equipped on the upside of the slide plate, bottom plate is equipped on the downside of the slide plate, one end that the bottom plate is contacted with blackboard is equipped with fur, the slide plate both ends are equipped with baffle, the baffle, bottom plate, bare electromagnet forms iron particle accommodating chamber after being contacted with blackboard, the iron particle of white coating is coated in iron particle accommodating chamber equipped with several peripheries, the blackboard top is equipped with the driving mechanism for driving slide plate to move up and down, blackboard-cleaning mechanism is set on the slide plate, blackboard-cleaning mechanism connection vibration dust-collection mechanism, the blackboard has collecting tank.Teacher can carry out setting-out at a distance, draw four line lattice specifications, while setting-out can blackboard wiping, and dust can absorb, and dust descends slowly and lightly seldom, and device is stable will not to damage blackboard. |
