technical field

The invention relates to a teaching device, in particular to a mechanical interactive teaching device.

Background technique

When doing machinery, the answers in mechanical teaching are essential. Most teachers will list many mechanical problems on the blackboard, and then the teacher will directly point students to answer them. Students are in a passive state and lack of interest, which indirectly leads to It is very important that students do not want to learn and the quality of teaching is not high. However, the current classroom teaching is weak in interaction, which leads to low interest of students in listening to the class, and at the same time, there are fewer places where students need to do it, which will reduce the efficiency of students' listening , thereby reducing the quality of teaching.

To further illustrate, it also includes a fourth strut and pads, the left and right sides of the top of the bottom plate are provided with a fourth strut, the top of the fourth strut is connected with a pad, and the pads on the left and right sides are connected with the left and right two respectively. Side pedal bottom contact.

When the device needs to be used for teaching, the teacher will tell the two students the questions that the students need to answer, and then the two students will stand on the left and right pedals respectively. After the students stand firmly, the teacher will control the motor to rotate counterclockwise to drive the left side The first gear on the right side rotates counterclockwise, which in turn drives the first gear on the right side to rotate clockwise. The students on it move upwards. When the students move upwards to a suitable height, the user controls the motor to stop working. Then the students open the cover through the handle and take out the chalk from the chalk box. After the chalk is taken out, the student puts the cover Put the cover on, when the students are ready, the teacher says to start, and the two students can start to answer. At the same time, the teacher controls the motor to rotate clockwise slowly, driving the first gear on the left to rotate clockwise, thus driving the first gear on the right The gear rotates counterclockwise, the rotation of the first gear drives the rack to move down, and then drives the guide sleeve to move down, thereby driving the pedal to move down, so that the student moves down. When the pedal moves down to the initial position, it is already When the time specified by the teacher arrives, the user controls the motor to stop working, and then the teacher looks at the students' answers, and then the teacher judges whether the students win or lose according to the students' answering speed and whether the answers are correct.

Because it also includes a completion reminder device, the base plate is provided with a completion reminder device, and the completion reminder device includes a hollow tube, a button, a spring, a connecting block, a push rod, a horn and a first bulb, and the left and right sides of the base plate are provided with a hollow tube.
