There are 4 balance bars on the upper part of the lifting control plate, the upper part of the balance bar is connected to the lifting platform, the middle part of the lifting control plate has a threaded sleeve connecting hole, and the threaded sleeve connecting hole is connected to the threaded sleeve, and the position of the threaded sleeve and the position of the rotation hole Correspondingly, the threaded sleeve is internally connected to the rotating shaft, the top of the rotating shaft is inserted into the rotating hole, the middle part of the rotating shaft has threads, and the threads mesh with the threaded sleeve, and the bottom of the rotating shaft is connected to the rotating motor. The rotating motor is connected to the power supply through the control line.

There is a control column at the bottom of the main body of the test bench, and there is a square control groove inside the control column. The structure of the square control groove is adapted to the lifting control plate, and the lifting control plate moves inside the square control groove.

The middle part of the main body of the test bench has a fixed plate connecting groove, and the fixed plate connecting groove is connected to the fixed plate, and the bottom of the square control groove has a motor slot, and the motor slot is connected to a rotating motor.

Beneficial effect:

The main body of the test bench is connected to the lifting platform through the lifting device. The bottom of the lifting platform has a fixed plate, and the middle part of the fixed plate has a supporting sleeve connection groove. Control panel, the upper part of the lifting control panel has 4 balance bars, the upper part of the balance bar is connected to the lifting platform, and the joint action of the 4 balance bars ensures the stability and high stability of the lifting platform during the lifting process. The middle part of the lifting control board has a threaded sleeve connecting hole, the threaded sleeve connecting hole is connected to a threaded sleeve, and the threaded sleeve is internally connected to a rotating shaft. The top of the rotating shaft is inserted into the rotating hole. The thread and the threaded sleeve are engaged with each other, the bottom of the rotating shaft is connected to a rotating motor, and the rotating motor is connected to a power supply through a control line. The motor drives the rotating shaft to rotate, and the lifting control panel moves up and down due to the mutual engagement of the thread and the threaded sleeve. There is a control column at the bottom of the main body of the test bench, and there is a square control groove inside the control column, and the lifting control plate moves inside the square control groove. When the lifting platform does not need to be lifted, the fixed plate returns to the connecting groove of the fixed plate, and the top surface of the lifting platform is kept on the same level as the top surface of the main body of the experimental table, forming an integrated body, which is beautiful and practical. This new type of physical experiment platform that is easy to lift is convenient for students to operate according to the experimental requirements, and the height of the lifting platform can be changed. The operation is simple, the experiment is convenient, and the experimental effect is improved.
