The invention relates to the radio communication major teaching experiment auxiliary equipment technical field, and specially relates to a radio communication major teaching experiment shielded box; the radio
communication device can be conveniently placed in the box body, so teachers can easily carry out radio communication major teaching experiments, thus improving practical values. After long term usage, a dirty transparent observation board can be easily wiped, thus allowing teachers to observe the radio
communication device in the work chamber, and improving the usage reliability; the shielded box comprises a box body, a storage plate, a base plate, a left electric telescoping cylinder, a right electric telescoping cylinder, a left stay
rope, a right stay
rope, a left first guide wheel, a left second guide wheel, a left guide ring, a right guide ring, a right first guide wheel, a right second guide wheel, four sets of reset springs, a driving shaft, a front driving rod, a rear driving rod, and a slide column; a rotary through hole penetrating back and forth is arranged in middle of the front end of the box body, and arranged in the lower middle portion of the transparent observation board; a mechanical seal is arranged in the rotary through hole.
