Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, English is carved in a kind of English teaching board convenient for adjusting, including board of education 1,1 upper surface of board of education
Letter 2 and three line lattice 3,1 bottom middle position of board of education are fixedly connected with link block 4, and 1 outer wall two sides of link block are fixedly connected with
There is fixed link 5,5 upper end of fixed link is fixedly connected on 1 lower end of board of education, it should be noted that link block 4 and upper flipping block 16 are logical
Bearing rotation connection is crossed, reaches when two sides be can't see by the student of wall in teacher, makes left side or right side by rotating board of education
Student can see, the downside of link block 4 is equipped with inner cylinder 6, and the lower end of link block 4 passes through the upper end of turnover mechanism 7 and inner cylinder 6
Rotation connection, it should be noted that turnover mechanism 7 includes the upper flipping block 16 being fixedly connected with 4 lower end of link block, upper flipping block
16 are equipped with through-hole, and 6 upper end of inner cylinder is fixedly connected with lower flipping block 17, and lower flipping block 17 is equipped with through-hole, the through-hole of upper flipping block 16
It after corresponding with the through-hole of lower flipping block 17, is secured with nuts after being connected to by bolt 20 with block, bolt 20 includes bolt, gear
Block, nut.
In the present invention, 6 lower end of inner cylinder is fixedly connected with limited block 8, and limited block 8 is equipped with upper and lower perforative threaded hole 9, spiral shell
9 internal screw thread of pit is connected with threaded rod 10, slides outside inner cylinder 6 and is equipped with outer cylinder 11, it should be noted that 11 inner wall of outer cylinder is equipped with limit
Position slot 12, limiting slot 12 is corresponding with limited block 8, when making limited block 12 move up and down under driving of the board of education in motor 14, outside
The limiting slot 12 that 11 inner walls of cylinder are equipped with avoids limited block 8 from rotating, and board of education 1 is caused to rotate, and 11 lower end of outer cylinder is fixed to be connected
It is connected to pedestal 19, particularly, the lower end of pedestal 19 is fixedly connected with sinker 18, prevents board of education 1 whole due to pedestal 19
It kicks the beam and topples over, mounting groove 13 is equipped in pedestal 19, is fixedly connected with motor 14 and battery 15, motor in mounting groove 13
It is electrically connected between 14 and battery 15, particularly, motor 14 selects 42 stepper motors, is adjusting height to limit board of education
When limiting altitude, the present invention, which has, to be solved to study English not convenient, and the height adjustment inconvenience of board of education 1 and angular adjustment are not
Just the problem of.The drive shaft of motor 14 and the lower end of threaded rod 10 are fixedly and coaxially connected.
Use process of the invention, when the student on classroom both sides can't see, horizontally rotates board of education 1, makes when giving lessons
The student on the left side or the right can see；When light makes board of education 1 occur reflective, by adjusting bolt 20, first by bolt
Cause relaxation is rotated counterclockwise, makes to turn to suitable position before and after board of education 1, then rotates clockwise bolt, bolt is in block
