| titleOfInvention | A kind of stable English teaching system for being conducive to teachers and students' health |
| abstract | The invention discloses a kind of stable English teaching systems for being conducive to teachers and students' health, including several magnet strips being arranged in blackboard and the sliding rail that blackboard left and right ends are arranged in, setting has the slide plate of idler wheel in the sliding rail, scraper plate 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, scraper plate forms iron particle accommodating chamber after contacting 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 on the slide plate, the blackboard-cleaning mechanism connects vibration dust-collection mechanism, the vibration dust-collection mechanism is equipped with dust non-proliferation mechanism.Teacher can draw lines at a distance, draw four line lattice specifications, can wipe blackboard while setting-out, and dust can absorb, dust descends slowly and lightly seldom, and device is stable will not to damage blackboard. |
