An intelligent business English polysemous word identification and analysis learner

Abstract

The invention relates to the technical field of English learning devices, and discloses an intelligent business English polysemous word discrimination and analysis learner, comprising a base box, the bottom of the base box is fixedly installed with a non-slip pad, and the inside of the base box is respectively provided with a first installation A slot and a second installation slot, a first connecting rod is fixedly installed inside the first installation slot, a first compression spring and a first sliding block are movably installed on the outside of the first connecting rod, and the first sliding block is installed. The top of the block is movably installed with a first rotating rod, which rotates by controlling the motor inside the first pin block. When the motor rotates, it will drive the second rotating shaft to rotate through its output shaft. A fixed tooth block drives the transmission belt to rotate. When the transmission belt rotates, the second fixed tooth block drives the third rotating shaft to rotate. When the third rotating shaft rotates, the connection block changes the inclination angle of the display screen.

[0003] After searching, Chinese Patent No. CN107331217B discloses an intelligent business English polysemous word discrimination learner, which includes a first brace, a second brace and a backboard, and the backboard includes a first folding board hinged by a second rotating shaft and a second folding board. Two folding plates, the second folding plate is hinged to the second support plate through the third rotating shaft, the first folding plate is hinged to the second supporting plate through the first rotating shaft; a flexible display screen is arranged above the front of the back plate; The height of the display of the learner can be adjusted appropriately, thereby reducing visual fatigue and increasing the convenience of the learner. At the same time, the display screen of the intelligent business English polysemous word discrimination learner can be folded. After the whole device is stored It occupies a small space and is easy to carry; however, it cannot support the learner when in use, and the learner cannot adjust the angle during use, which is inconvenient for the user and affects the efficiency of the use of the learner. low
